Cost Aspect in the Stability Analysis of an Earthfill Dam with Respect to Variations in Embankment Materials and Water Levels (Case Study: Cibeet Dam Project, Bogor Regency)

2026-04-24T07:45:57+00:00

Stability analysis was carried out using PLAXIS 2D based on the Finite Element Method with the Shear Strength Reduction (SSR) approach. Two design alternatives were evaluated: Model 1 with a complete material zoning system consisting of sand–gravel, sandstone, and coarse filter layers, and Model 2 with a simplified configuration dominated by sandstone material. The evaluation was performed under Low Water Level (LWL), Normal Water Level (NWL), and Flood Water Level (FWL) conditions, as well as under static loading, Operating Basis Earthquake (OBE), and a design earthquake with a magnitude of 7.5. The results indicate that increasing reservoir water levels and seismic loading lead to a reduction in the Safety Factor (SF); however, all analyzed conditions still satisfy the required stability criteria. Model 2 exhibits higher SF values under static conditions, while Model 1 demonstrates superior stability performance under strong earthquake loading and long-duration seismic events. Cost analysis shows that the total construction cost of Model 1 is IDR 566.85 billion, whereas Model 2 requires IDR 558.86 billion, resulting in a cost saving of 1.41% for Model 2. The integrated analysis reveals a clear trade-off between stability and cost, where Model 1 provides higher technical safety, while Model 2 offers greater economic efficiency.

Information Management Behavior Related to the Self-Diagnosis of Mental Health Disorders by the Generation

2026-04-24T06:22:41+00:00

The rapid growth of social media, particularly TikTok, has significantly influenced how Generation Z accesses and manages mental health information, leading to an increasing trend of self-diagnosis. However, previous studies have primarily focused on the impacts of self-diagnosis rather than the underlying information management process, creating a research gap. This study aims to explore how Generation Z manages mental health information on TikTok and how this process contributes to self-diagnosis behavior. Using an interpretive paradigm with a qualitative phenomenological approach, data were collected through in-depth interviews with Generation Z TikTok users and an expert informant, selected through purposive sampling. The data were analyzed using thematic analysis supported by NVivo 12. The findings reveal that information exposure initially occurs passively through TikTok’s algorithmic For You Page, which later develops into active information seeking. The interpretation and selection of information are largely influenced by emotional validation rather than scientific reasoning, while social interaction reinforces perceived credibility. This process leads to the formation of self-perception and self-diagnosis decisions. The study concludes that self-diagnosis is a subjective and gradual outcome of information management driven by media dependency. Theoretically, this research extends information behavior and media dependency frameworks, while practically emphasizing the need for improved digital mental health literacy and professional guidance.

Pkpu in Indonesia and its Comparison with the United Arab Emirates (Difc Insolvency Law)

2026-04-05T18:09:45+00:00

Debt restructuring is a key legal instrument to prevent liquidation and support debtor recovery. Indonesia applies the PKPU mechanism, while the DIFC uses the Insolvency Law No. 1 of 2019, reflecting different legal approaches that require comparative analysis. This research aims to analyze and compare the debt restructuring mechanism in the PKPU system in Indonesia and the Insolvency Law of DIFC, as well as assess its effectiveness in providing legal protection for debtors and creditors. This study uses normative legal methods with a statutory approach and a comparative approach. Data were obtained through literature studies and analyzed descriptively-analytically and comparatively. The results show that PKPU in Indonesia focuses on a peace mechanism through the approval of the majority of creditors with a certain time limit, while the DIFC Insolvency Law provides greater flexibility through a modern restructuring scheme with an international principles-based approach. The DIFC also provides stronger protection for creditors through transparency and more structured court oversight. In general, both systems have the same goal of saving the debtor's business and providing legal certainty for creditors. However, the restructuring mechanism in the DIFC tends to be more adaptive to international business practices, while PKPU in Indonesia still has some limitations in terms of efficiency and legal protection. Regulatory reform in Indonesia is needed to increase competitiveness and legal certainty in debt settlement.

Management of Kapuas River Water as a Sustainable Raw Water Source for Drinking Water Supply in Pontianak City

2026-04-24T08:23:30+00:00

The Kapuas River in Pontianak City plays a vital role as a source of raw water for drinking water supply and various other needs. However, the quality of the river water is under increasing pressure due to the activities of surrounding communities. A sustainable management strategy is therefore necessary to maintain both water quality and availability, for human consumption as well as ecosystem sustainability. This study employed a mixed-methods approach encompassing descriptive analysis, regression analysis, and a SWOT framework. The findings indicate that the water quality of the Kapuas River is generally still within the applicable quality standards. Communities residing along the river generally collect and treat water prior to use, representing a form of adaptive response to prevailing water quality conditions. The analysis further reveals that fluctuations in basic drinking water tariffs are influenced by the rate of water loss, or Non-Revenue Water (NRW), which constitutes one of the primary challenges in the provision of clean water services. Based on the SWOT analysis, the recommended sustainable management strategy falls within the WO (Weakness–Opportunity) quadrant, signaling the need for increased funding, enhanced resource capacity, and stronger policy support to reinforce the water management system. Furthermore, regular water quality monitoring and consistent follow-up measures are essential steps to ensure that the Kapuas River remains a safe and reliable source of water for the population of Pontianak City.

Anti-Inflammatory Potential of Active Compounds in Moringa Leaves (Moringa Oleifera) Against Osteoarthritis Through in Silico Methods

2026-04-24T04:30:12+00:00

Osteoarthritis (OA) is a degenerative joint disease with a high global burden. Available therapies remain palliative, and selective COX-2 inhibition risks shifting arachidonic acid metabolism to the 5-lipoxygenase (5-LOX) pathway, which increases proinflammatory leukotrienes. Furthermore, no approved 5-LOX inhibitors exist for OA. This study aims to analyze the anti-inflammatory potential of active metabolites in moringa leaves as 5-LOX inhibitors in osteoarthritis using in silico methods. This study was conducted using in silico methods, including preparation of ligand and target protein structures, identification of binding sites, docking validation, molecular docking, and visualization of molecular interactions. Molecular docking was performed using AutoDock Vina software via PyRx to evaluate binding energy (ΔG). All moringa leaf metabolites bound stably to both the orthosteric and allosteric pockets of 5-LOX, with binding affinities competitive with those of the reference ligands particularly ellagic acid (ΔG = −7.7 kcal/mol) at the orthosteric site and isorhamnetin (ΔG = −8.3 kcal/mol) at the allosteric site. Docking validation confirmed the reliability of the method, supporting the feasibility of active metabolite compounds from moringa leaves as potential 5-LOX inhibitor candidates in osteoarthritis. Active metabolites of moringa leaves show potential as 5-LOX inhibitors with competitive affinity at orthosteric and allosteric sites, and may thus be developed as complementary anti-inflammatory agent candidates in osteoarthritis. However, further validation through in vitro and in vivo testing is required.

The Effect of the Combination of Tempeh Flour and Kepok Banana Peel Flour (Musa paradisiaca Linn.) on the Chemical and Organoleptic Quality of Butter Cookies

2026-05-01T10:56:00+00:00

Butter cookies are one of the most popular food products due to their crispy texture and distinctive flavor. Tempeh flour, as a source of plant-based protein, and kepok banana peel flour (Musa paradisiaca Linn.), as a source of dietary fiber, have significant potential to be utilized as functional ingredients in cookie product development. This study aimed to determine the effect of combining tempeh flour and kepok banana peel flour on the chemical and organoleptic quality of butter cookies. This research employed a laboratory experimental method using a Completely Randomized Design (CRD) with one factor, namely variations in flour combination concentrations: T1P1 (90% : 10%), T2P2 (80% : 20%), T3P3 (70% : 30%), and T4P4 (50% : 50%), each with three replications. The observed variables included chemical quality (moisture content, ash content, protein content, and fiber content) and organoleptic quality (color, aroma, taste, texture, and overall acceptability) of butter cookies. Parametric data were analyzed using Analysis of Variance (ANOVA) with the assistance of Statistical Product and Service Solutions (SPSS) software, while non-parametric data were analyzed using Duncan’s Multiple Range Test (DMRT). Based on the effectiveness test using the De Garmo method, treatment T2P2 was selected as the best treatment with a total score of 0.626, producing the most optimal physicochemical and organoleptic characteristics.

Business Development Strategy for Mechanical Electrical Plumbing Contractor at PT Vastorindo Djaya Semesta

2026-04-24T08:21:52+00:00

The mechanical, electrical, and plumbing (MEP) construction industry faces external pressures in the form of tightening infrastructure budgets, price-based tender competition, and the accelerated adoption of digitalisation such as Building Information Modelling (BIM), which demands an increase in contractors' internal capabilities. This study aims to formulate a business transformation strategy for PT Vastorindo Djaya Semesta (PT VDS) as a MEP contractor through a comprehensive analysis of the external-internal environment and an industry foresight approach. The research uses primary data (observations, in-depth interviews, and internal-external expert questionnaires) and secondary data (literature studies). The analysis was conducted through industry foresight, PESTEL and Porter's Five Forces for the external environment, value chain analysis and VRIO for the internal environment, followed by the preparation of IFE–EFE, IE Matrix, and SWOT/TOWS matrices to produce alternative strategies, and priority determination using AWOT (a combination of SWOT and AHP). The analysis results placed PT VDS in Cell V of the IE Matrix (hold and maintain), indicating the need to maintain core performance while selectively strengthening internal capabilities. This study provides priority strategy guidelines that PT VDS can use to strengthen its competitiveness and business sustainability through capability transformation and refinement of its service value proposition in the MEP construction market.

A Systematic Review of Continuance Intention to Use Mobile Health (2020–2024)

2026-05-01T11:05:29+00:00

The rapid advancement of digital technologies in healthcare has led to the widespread adoption of mobile health (mHealth) applications, offering users convenient access to health services. However, despite increasing downloads, many users discontinue usage after initial adoption, highlighting the issue of low continuance intention. This paper aims to systematically review the empirical literature to identify the key factors influencing users’ continued use of mHealth applications. A systematic literature review (SLR) was conducted using the PRISMA 2020 protocol and structured with the PICO framework. A total of 20 peer-reviewed studies published between 2020 and 2024 were analyzed. The review identified that perceived usefulness, satisfaction, ease of use, and trust are the most frequently studied and influential factors. Several theoretical models, such as the Technology Acceptance Model (TAM), Expectation-Confirmation Model (ECM), Unified Theory of Acceptance and Use of Technology (UTAUT), and Self-Determination Theory (SDT), were also widely applied. Additionally, the findings suggest that contextual elements like age, digital literacy, and chronic health conditions significantly affect continuance intention, especially among the elderly and specific user groups. The results of this study provide a comprehensive understanding of the multidimensional determinants of sustained mHealth usage and offer valuable insights for application developers, healthcare providers, and researchers to design more user-centered and effective digital health solutions.

Implementation of Narcotics Eradication Policy to Reduce Narcotics Circulation at Class IIA Tanjung Raja Correctional Facility

2026-04-24T04:12:12+00:00

This study aims to analyze the implementation of the narcotics eradication policy at the Tanjung Raja Class IIA Correctional Facility (Lembaga Pemasyarakatan Kelas IIA Tanjung Raja) and to identify the factors influencing the effectiveness of its rehabilitation program. A qualitative research design was employed, utilizing in-depth interviews with inmates and correctional officers, participant observation, and document analysis as data collection methods. The findings indicate that although positive steps have been undertaken such as the establishment of a dedicated task force and the implementation of a rehabilitation program the outcomes achieved have not been satisfactory. A reduction in narcotics circulation from 30% to 25% following one year of implementation does not reflect significant progress. Inhibiting factors, including budget constraints, human resource shortages, social stigma, and insufficient inter-agency coordination, contributed to weaknesses in policy implementation. These findings underscore the importance of improving rehabilitation facilities, providing capacity-building training for correctional officers, and strengthening collaboration among relevant agencies. Consequently, achieving effective narcotics eradication requires a more holistic and integrated approach involving all relevant stakeholders, including the government, the community, and the families of inmates. This study is expected to provide actionable recommendations for future policy improvement.

The Effect of Bajakah Wood Extract on Collagenase Activity of Glycated Proteins in Rats and its Review from an Islamic Perspective

2026-04-24T07:02:46+00:00

Skin aging is a biological process that is influenced by oxidative stress and the accumulation of advanced glycation end products (AGEs) that can increase the activity of the collagenase enzyme so that it causes collagen degradation. Red logan wood (Spatholobus littoralis Hassk.) is known to have antioxidant content that has the potential to inhibit this process. This study aimed to determine the effect of administration of ethanol extract of red logs on collagenase activity in male white rats of the Sprague-Dawley strain induced by D-galactose. This study is a laboratory experimental research with a post-test only control group design. A total of 36 rats were divided into six groups, namely the blank group, negative control, positive control, and three treatment groups given red bajakah wood ethanol extract with doses of 25 mg/kgBB, 50 mg/kgBB, and 100 mg/kgBB. Induction of aging was carried out using D-galactose, then serum collagenase activity was measured using the ELISA method. Data were analyzed using a one-way ANOVA test followed by an LSD test with a significance level of p < 0.05. The results showed that the administration of ethanol extract of red logs was able to significantly reduce collagenase activity compared to the negative control group (p < 0.05). Doses of 100 mg/kgBB showed the greatest decreasing effect and were close to positive control groups. This suggests that red logwood extract has the potential to be a natural anti-aging agent through a mechanism of inhibition of collagen activity.

Marketing Strategy and the Role of Public Relations in the Fintech Lending User Acquisition Process: A Case Study of Bantusaku in Indonesia

2026-04-24T07:44:28+00:00

The rapid growth of the financial technology (fintech) industry in Indonesia has led to the emergence of various lending platforms that provide easy access to financing. However, public trust dynamics, strict regulations, consumerist behaviors, and increasing competition require companies to implement integrated and ethical communication strategies. This study aims to analyze the marketing strategies and public relations (PR) roles in the user acquisition process of the BantuSaku fintech lending platform in Indonesia, as well as to identify the challenges encountered. Employing a qualitative approach with a constructivist paradigm, data were collected through in-depth interviews with BantuSaku internal teams, active users, and industry observers, supported by secondary data including company documents, OJK regulations, and digital content. Analysis was conducted using Miles & Huberman’s (2014) interactive model, covering data reduction, data display, and verification. Findings indicate that marketing strategies emphasizing financial education and transparency, combined with PR efforts focused on building a positive image and managing reputation, significantly contribute to user acquisition and retention. Nevertheless, the effectiveness of these strategies is influenced by low financial literacy, competition with illegal lending services, and default risks. This study highlights the importance of integrating education-based and ethical marketing and PR strategies as a key factor for sustainable growth in fintech lending.

Public Innovation Governance in Regional Data Integration: An Analysis of the Simata Policy in South Sumatra

2026-05-01T11:02:57+00:00

Regional data integration is a crucial element in the digital transformation of bureaucracy, but its implementation is often faced with structural tensions between technical regulatory demands and strong sectoral egos. In South Sumatra Province, the One Data Information System (SIMATA) was initiated as a form of public innovation to break the information fragmentation impasse between Regional Apparatus Organizations (OPDs). This study aims to examine the implementation of SIMATA policies using the analytical framework of Public Innovation Governance. Through a qualitative method with a policy analysis approach, this study dissects strategic documents, regulatory instruments managed by the South Sumatra Provincial Diskominfo, and data governance practices at the regional level. The results of the analysis show that the effectiveness of SIMATA implementation is not solely determined by technological determination, but is highly dependent on the capacity of actor orchestration and administrative regularization. It was found that there is a contradiction between the formal data integration mandate and the institutional readiness of OPDs in the field. In this context, the Public Innovation Governance model serves as a bridging instrument capable of shifting passive bureaucratic compliance patterns into proactive network collaboration. This study concludes that the sustainability of SIMATA requires governance adaptation that goes beyond traditional hierarchical approaches, leading to a more adaptive innovation ecosystem. This study makes a theoretical contribution to the digital governance policy literature and offers practical recommendations for strengthening the One Data governance architecture at the local government level.

2026-04-24T04:13:21+00:00

This study aims to examine students' perceptions of the Basic Discipline and Leadership Training Program (Latihan Dasar Kedisiplinan dan Kepemimpinan/LDKK) from the perspective of Psychological Capital among students of Universitas Jenderal Achmad Yani (UNJANI). A quantitative explanatory research design was employed. The sample consisted of 240 undergraduate students who had participated in the LDKK program, selected through purposive sampling. Data were collected using a Psychological Capital questionnaire encompassing four dimensions self-efficacy, hope, optimism, and resilience as well as a scale measuring students' perceptions of LDKK. Data analysis was conducted using multiple linear regression with SPSS. The results indicate that Psychological Capital has a significant simultaneous effect on students' perceptions of LDKK (R² = 0.42; p < 0.001). Partially, self-efficacy, hope, optimism, and resilience each exerted a positive and significant effect on students' perceptions of LDKK (p < 0.05). These findings suggest that students with higher levels of Psychological Capital tend to perceive the LDKK program more positively. This study highlights the importance of positive psychological resources in shaping students' perceptions of leadership and discipline training in higher education. Practically, the findings suggest that integrating Psychological Capital development into the design and implementation of LDKK may enhance program effectiveness and students' overall learning experience.

Economic Feasibility Study of the Multi-Utility Tunnel (MUT) Project in the New Capital City of Nusantara (IKN) During the Budget Efficiency Period

2026-04-24T04:33:21+00:00

The development of Ibu Kota Nusantara (IKN) has faced considerable uncertainty following the implementation of government budget efficiency policies in 2025, which may affect the feasibility of key infrastructure, including the Multi-Utility Tunnel (MUT). This study aims to evaluate the feasibility of MUT development under budget efficiency conditions by analyzing its economic, social, and environmental dimensions to support informed decision-making by relevant stakeholders. The Life Cycle Cost (LCC) method is applied using structural design data and applicable regulations, while project implementation is assessed through scenario-based simulation and forecasting. Economic feasibility is analyzed using Net Present Value (NPV) and sensitivity analysis, whereas social and environmental impacts are evaluated through systematic observation. The analysis identifies three possible development scenarios: optimistic, moderate, and pessimistic. The moderate scenario exhibits the highest initial and operational costs when cash inflows are excluded. To achieve economic feasibility at an NPV of zero, the pessimistic scenario requires the highest total cash inflow, amounting to IDR 1.074 trillion during the operational phase. Among the three variables analyzed, initial cost is the most sensitive parameter, recording the highest sensitivity value of 24.34 under both the pessimistic and moderate scenarios. In contrast, the discount rate is the least sensitive variable, with a sensitivity value of −9.00 across all scenarios. In terms of social impact, budget efficiency may affect public trust in the project, while environmentally, it may reduce immediate adverse impacts but risk prolonging long-term environmental effects.

The Implications of Supreme Court Circular Letter No. 3 of 2023 on the Application of the Paritas Creditorium Principle in the Bankruptcy of Apartment Developers

2026-04-27T03:52:32+00:00

This study examines the implications of the Supreme Court Circular Letter (SEMA) No. 3 of 2023 on the application of the paritas creditorium principle in bankruptcy cases involving apartment developers in Indonesia. The regulation has created a normative tension between the universal nature of bankruptcy law under Law No. 37 of 2004 on Bankruptcy and Suspension of Debt Payment Obligation and the judicial restriction imposed by SEMA, which states that bankruptcy petitions against apartment developers do not fulfill the requirement of simple proof. Using a normative juridical methodology with descriptive-analytical specifications, this research is grounded in literature studies of primary, secondary, and tertiary legal sources, supported by case analysis and expert interviews. The findings reveal that SEMA No. 3 of 2023 substantially degrades the implementation of the paritas creditorium principle, limits creditors’ access to collective debt resolution mechanisms, and creates legal uncertainty through dualism of norms between statutory provisions and judicial circulars. As a result, creditors—particularly consumer creditors—are compelled to seek alternative legal remedies through civil litigation, including class action lawsuits accompanied by conservatoir beslag and execution mechanisms. This study contributes to the development of bankruptcy law discourse and offers practical recommendations to restore fairness, certainty, and effectiveness in resolving debt disputes involving apartment developers.

Designing Policies for the Empowerment of Older Adults Through Used Cooking Oil Management Within the Social Protection Framework

2026-05-01T10:49:42+00:00

The increasing number of the elderly population in Indonesia demands a transformation of social protection policies that are not only protective, but also productive and sustainable. This research aims to formulate a policy design for the empowerment of the elderly through the management of used cooking oil in the framework of social protection based on collaborative governance. The research uses a qualitative approach with literature study methods and conceptual analysis of circular economy-based empowerment policies and practices. The results of the study show that the social protection policy of the elderly in Indonesia is still dominated by a charitable approach, so it has not been able to optimize the potential of the elderly as economic actors. On the other hand, used cooking oil management has significant economic and ecological potential, but has not been systematically integrated into policy design. The integration of these three dimensions allows for effective cross-sectoral collaboration between government, society, and the private sector. Therefore, this study recommends the transformation of the role of the government, especially the Ministry of Social Affairs, as a metagovernor who is able to orchestrate collaboration between actors in developing policies for the empowerment of the elderly based on the circular economy. This policy design is expected to improve the welfare of the elderly, strengthen social inclusion, and support sustainable development.

The Relationship Between Parenting Styles and Speech Delay in Children Under 5 Years Old at YARSI Hospital and Its Review in Islam

2026-04-24T07:27:46+00:00

This study aimed to determine the relationship between child parenting styles and the incidence of speech delay in children under 5 years old at YARSI Hospital. A quantitative analytical cross-sectional design was used with total sampling of 102 children diagnosed with speech delay over 6 months. Parenting styles were assessed for seven caregiver types (father, mother, grandfather, grandmother, uncle, aunt, domestic assistant/ART). Speech delay was classified as functional (environmentally-driven) or non-functional (biologically-linked). For fathers, permissive indulgent parenting was dominant (35.3%). For mothers, authoritarian parenting was dominant (39.2%). Functional speech delay occurred in 72 children (70.6%), while non-functional speech delay occurred in 30 children (29.4%). Bivariate analysis using Chi-Square showed a significant relationship between maternal parenting style and speech delay (p = 0.027). Notably, all non-functional speech delay cases occurred in the authoritarian parenting group, while authoritative parenting had zero non-functional cases. Domestic assistant (ART) parenting also showed a significant relationship with speech delay (p = 0.046). These findings underscore the importance of verbal stimulation in parenting settings, including from domestic assistants, in supporting children's language development. From an Islamic perspective, children are a trust (amanah), and parents bear responsibility for responsive, communicative child-rearing.

The Role of Logistics Service Quality in Mediating the Influence of Air Cargo Packaging, Digital Information, and Air Cargo Tariff on Logistics Customer Retention at Silkargo Cikarang

2026-04-21T19:54:02+00:00

This research aims to analyze the influence of air cargo packaging, digital information, and air cargo tariffs on logistics customer retention through logistics service quality at SIL Kargo Cikarang. The background of this research is based on the decline in air cargo revenue from 2021 to 2025, the increasing rate of goods damage, digital misinformation, and relatively higher shipping rates compared to competitors. The research employed a quantitative approach using a survey method involving 125 customers of SIL Kargo Cikarang. The data analysis technique used was Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results of the study show that air cargo packaging, digital information, and air cargo tariffs have a positive and significant effect on logistics service quality. Logistics service quality also has a positive and significant effect on logistics customer retention and is able to mediate the influence of the three exogenous variables on logistics customer retention. These findings confirm that improving logistics service quality is a key strategy in retaining customers in the competitive air cargo industry.

The Effect of n-Butanol Extract of Dewandaru Fruit (Eugenia uniflora L.) on the Leukocyte Count in Mice Exposed to Cigarette Smoke

2026-04-24T07:33:43+00:00

Dewandaru (Eugenia uniflora L.) is a medicinal plant that has been widely used in traditional medicine. Cigarettes are addictive substances that pose a significant threat to health and life sustainability. The principal toxic constituents of cigarettes are nicotine, tar, and carbon monoxide (CO). Long-term smoking can increase the total leukocyte count, particularly the number of polymorphonuclear neutrophils (PMN) in the peripheral blood circulation, due to free radical generation and inflammatory reactions. Dewandaru fruit (Eugenia uniflora L.) contains antioxidant and anti-inflammatory compounds that may inhibit leukocyte activation induced by oxidative stress associated with cigarette smoke exposure, thereby contributing to a reduction in the total leukocyte count. This study employed an experimental design with a posttest-only control group, using a sample of 30 male mice (Mus musculus) divided into three groups. Group I served as the negative control and received cigarette smoke exposure and distilled water. Groups II and III were designated as treatment groups and received 30 minutes of cigarette smoke exposure per day for 30 days, along with oral administration of n-butanol extract of dewandaru fruit at doses of 100 mg/kgBW and 200 mg/kgBW, respectively. On day 31, peripheral blood samples were collected from all subjects. The findings of this study indicate that administration of n-butanol extract of dewandaru fruit (Eugenia uniflora L.) resulted in a reduction in the total leukocyte count in male mice receiving the extract compared to the control group.

The Impact of EWOM, Brand Image, and Content Marketing on Purchase Decision with Country of Origin as a Moderating Variable

2026-04-28T22:14:14+00:00

The increasing need for clean water in industrial areas demands a reliable and sustainable water supply system. This study aims to determine the optimal strategy for meeting clean water supply through optimizing the operational and maintenance costs of the water utility network at WTPs in industrial areas. The strategies analyzed include O&M strategies, small CAPEX strategies through the implementation of Streaming Current Monitors (SCMs) and supporting instrumentation, and large CAPEX strategies in the form of WTP construction or expansion. The research method uses Present Value (PV) and Life Cycle Cost (LCC) based financial analysis with a 20-year analysis period and a discount rate of 8%, based on historical WTP operational data and investment estimates. Scenario and sensitivity analysis were conducted to strengthen decision making. The results showed that the O&M strategy is the most optimal strategy and is the main priority because it provides the highest cumulative cost savings without initial investment, with PV Saving OPEX and MEX of IDR 230.07–677.51 million, and IDR 495.26 million in the moderate scenario. Small CAPEX strategy produces a positive NPV Saving of IDR 51.48 million but is sensitive to initial investment and the level of chemical savings. Meanwhile, the large CAPEX strategy has a Total Life Cycle Cost of IDR 57,415.00 million and is more appropriate as a medium to long-term solution to increase capacity and supply reliability. This study recommends implementing the strategy in stages to maintain the sustainability of clean water services and the efficiency of industrial area operational costs.

Evaluation and Prediction of Land Cover Changes in the Jangkok Watershed Using the Approach Ca-Ann

2026-04-24T06:54:52+00:00

This study addresses the increasing concern over deforestation and land cover changes in watershed areas, particularly in the Jangkok Watershed, West Nusa Tenggara, Indonesia. Rapid land conversion driven by population growth, agricultural expansion, and accessibility has contributed to forest degradation, potentially disrupting hydrological functions and ecosystem stability. Therefore, this research aims to evaluate land cover changes from 2019 to 2024 and to predict future changes until 2039 using an integrated modeling approach. The study employs remote sensing data derived from Landsat-8 OLI (2019) and Landsat-9 OLI-2 (2022 and 2024), processed through image pre-processing, classification, and accuracy assessment using ground checks, error matrix, and Kappa statistics. Furthermore, land cover change analysis is conducted using transition matrices, while the direction of change is evaluated using Curve Number (CN) and Soil Hydrology Group (KHT). Future predictions are generated using the Cellular Automata–Artificial Neural Network (CA–ANN) model based on driving factors such as distance to roads, rivers, and slope. The results indicate a significant decrease in primary and secondary dryland forests, accompanied by a substantial increase in mixed garden areas. Negative land cover changes dominate, leading to increased surface runoff and reduced infiltration capacity. The CA–ANN model demonstrates good predictive performance (Kappa = 0.78), projecting continued forest decline until 2039. In conclusion, land cover changes in the Jangkok Watershed are predominantly driven by human activities and pose risks to environmental sustainability. Strategic land management and conservation policies are essential to mitigate further degradation and preserve watershed functions.

ICD Coding Automation Model of Retinal Detachment Case Using Support Vector Machine and Random Forest

2026-04-24T04:33:34+00:00

Health Information Management (HIM) professionals are responsible for maintaining the consistency of ICD-based clinical codes for the health reimbursement and health analytics through the review of medical documentation. The complexity of coding rules and clinical pathways increases the risk of miscoding, but the implementation of Electronic Medical Record (EMR) opens opportunities for the development of automation of ICD coding. This study aims to build an ICD code automation model for retinal detachment cases from eye referral hospital using artificial intelligence through clinical text classification with Natural Language Processing (NLP) and Machine Learning (ML) algorithms. The dataset includes disease resumes, physical examinations, diagnoses, medical procedures, surgical records, and therapies from 300 inpatients. Text preprocessing uses the NLTK library through sentence splitting, abbreviation expansion, case folding, stop word removal, and tokenization functions. Data preparation involves splitting data (80:20 ratio), feature extraction with TF-IDF Vectorizer, and 5-fold cross validation. Classification modeling uses Support Vector Machine (SVM) and Random Forest (RF). Evaluation of the SVM model showed an accuracy of 0.82 (precision 0.84; recall 0.82; F1-Score 0.82), while the RF model achieved an accuracy of 0.87 (precision 0.88; recall 0.87; F1-Score 0.87). Based on confusion metrics, the correct predictions for classes H33.0, H33.2, and H33.4 on SVM are 79, 87, and 80, while RF reaches 83, 88, and 91. The development of this automation requires HIM professional’s role in ensuring the quality of EMR data and accuracy of ICD code as well as intensive model training to handle the complexity of clinical data.

Juridical Analysis of Online Gambling Crimes from the Perspective of the Criminal Code (KUHP) and the ITE Law: A Study of Decision No. 36/Pid.Sus/2025/PN MJY

2026-01-24T08:47:58+00:00

The development of information technology has expanded the forms and modes of gambling conducted through electronic systems, thereby requiring adjustments in the framework of regulation and the application of criminal law. This research aims to analyze the regulation of gambling offenses from the perspectives of the KUHP and the UU ITE, as well as to examine the application of Article 45 paragraph (3) in conjunction with Article 27 paragraph (2) of the UU ITE to the defendant in the said decision based on the prevailing legal normative construction. The research method used was normative legal research with a statutory approach and a case approach, conducted through the examination of statutory regulations, criminal law doctrines, and legal considerations contained in court decisions. The results of the research show that the KUHP as lex generalis regulates gambling by emphasizing acts of providing, giving opportunities, as well as participating in gambling activities as regulated in Article 303 and Article 303 bis of the KUHP. Meanwhile, the UU ITE as lex specialis contains regulations concerning acts of distributing, transmitting, or making accessible electronic information containing gambling content as regulated in Article 27 paragraph (2), which conceptually are directed at parties who act as providers, operators, or facilitators of online gambling. This research affirms that the differences in regulatory character between the KUHP and the UU ITE require a systematic legal interpretation of the function and purpose of each norm.

Technological Pedagogical and Content Knowledge (TPACK) Based Learning to Improve Student Learning Achievement at SDN Pekojan 03 and SDN Pekojan 05 Tambora, West Jakarta

2026-04-24T03:36:05+00:00

Technological Pedagogical and Content Knowledge (TPACK)-based learning is a strategic agenda for improving the quality of education in primary schools. Teachers, as the main implementers of instruction, require systematic management support to effectively integrate technology, pedagogy, and content. This study aims to describe the management of TPACK-based learning through the POAC (Planning, Organizing, Actuating, Controlling) framework in enhancing student achievement at SDN Pekojan 03 and SDN Pekojan 05 Jakarta Barat. The research employed a qualitative approach with a case study design through observations, interviews, and document analysis involving principals, teachers, and students. The findings reveal that planning for TPACK-based learning has been incorporated into instructional documents, yet its implementation remains inconsistent; organizing is still simple with limited ICT management teams; actuating involves the use of digital applications and interactive media, though not evenly across all classrooms; and controlling tends to focus more on administrative compliance rather than in-depth reflection on TPACK effectiveness. Limited facilities, teachers’ digital literacy, and unstable internet connectivity emerge as the main challenges, although both principals and teachers demonstrate strong commitment to sustaining digital learning innovation. The study concludes that applying POAC in TPACK-based learning has the potential to enhance teacher creativity, student engagement, and learning achievement, provided that it is supported by needs-based planning, structured team organization, collaborative implementation, and reflective as well as continuous supervision. It is expected that this study contributes to the development of adaptive, innovative, and sustainable TPACK-based learning policies and practices in primary schools.

Hedging Energy Security through Infrastructure Diplomacy: The Pursuit of Economic Sovereignty in Azerbaijan-Indonesia Energy Cooperation Post-COP29

2026-05-01T11:01:23+00:00

In the wake of COP29 in Baku, the geopolitical landscape of energy has transitioned toward a "hybrid" cooperation model that balances fossil fuel reliability with green innovation. This study analyzes the strategic partnership between Azerbaijan and Indonesia (2024–2026), examining how infrastructure diplomacy serves as a mechanism for economic sovereignty. Amidst a 2026 global oil surplus and a 2.5 mb/d supply increase buffer, the research identifies a significant pivot toward sustainable infrastructure. The findings highlight the "Baku Legacy": a Joint Task Force on Green Energy acting as a "special vehicle" to bypass bureaucratic hurdles in the Waste-to-Energy (WtE) sector. Data validates that while the Baku-Tbilisi-Ceyhan (BTC) pipeline remains a critical artery for Indonesia’s oil stability—mitigating the $6/bbl price spikes seen in early 2026—the cooperation has expanded into "Pragmatic-Progressive" ESG standards. By integrating Neorealist and Constructivist frameworks, the paper concludes that this bilateral synergy allows both nations to hedge against global volatility and supply chain shocks. This "Middle-Power Standard" offers a balanced alternative to stringent Western mandates, securing strategic autonomy within the South-South green transition.

The Role of Teachers in Implementing the Problem Based Learning Model Comic Education in Reading of Elementary School Students

2026-04-24T07:46:12+00:00

This study addresses the persistent issue of low reading comprehension among elementary school students, which remains a critical challenge in achieving effective literacy learning. In many classrooms, reading instruction is still dominated by teacher-cantered approaches, resulting in limited student engagement and superficial understanding of texts. To overcome this problem, innovative learning strategies that integrate interactive models and engaging media are needed. This research aims to examine the implementation of the Problem-Based Learning (PBL) model assisted by educational comic media and its impact on students’ reading comprehension. This study employed a descriptive qualitative approach supported by simple quantitative data. The subjects were 26 fourth-grade students of an elementary school. Data were collected through observation, reading comprehension tests, and documentation. The implementation followed PBL stages, including problem presentation, group discussion, exploration, and reflection, using educational comics as learning media. The results indicate that the integration of PBL and educational comics significantly improved students’ reading comprehension and engagement. The percentage of students achieving the minimum competency standard increased from 65% in the pre-implementation phase to 84% after the intervention. Students demonstrated better ability to identify characters, interpret text, analyze content, and draw conclusions. In conclusion, the PBL model assisted by educational comic media is effective in enhancing reading comprehension and fostering active learning. This approach can serve as an alternative strategy to improve literacy instruction in elementary schools.

Challenges of Integrating Green Skills in the Indonesian Vocational Training System

2026-04-24T04:31:17+00:00

The transition toward a green economy necessitates a workforce equipped with green skills as a core competency to support industrial sustainability and competitiveness. However, the integration of green skills into the vocational training system in Indonesia continues to face various structural challenges and has yet to be managed in a systematic manner. This study aims to analyze the concept of green skills through the lens of the most recent literature, identify the challenges of their integration within vocational training institutions, and examine early practices of green skills implementation through a case study at the LPP Quantum Sampit Vocational Training Institute (Lembaga Pelatihan Profesi Quantum Sampit). The research employed an integrative literature review combined with an explanatory case study approach, utilizing policy document analysis, international reports, and graduate tracer data from LPP Quantum Sampit for the period 2022–2025. The findings reveal six principal challenges in the integration of green skills: limitations in the existing policy framework; a curriculum that is not yet oriented toward green principles; insufficient instructor competence; inadequate training facilities and equipment; increasingly complex industry demands; and the absence of established green skills certification standards. These findings serve as the basis for the formulation of conceptual recommendations in the form of a five-pillar green skills integration framework, proposed as a strategic effort to strengthen the vocational training system in supporting Indonesia's transition to a green economy.

Gender Gap in Workforce Participation in West Nusa Tenggara Province

2026-04-27T03:51:13+00:00

Gender participation gap in the workforce is influenced by various factors, including income, age, education, marital status, family size, culture, and social norms. In Nusa Tenggara Barat (NTB), understanding these factors is crucial to addressing gender disparities in employment participation. Despite widespread acknowledgment of cultural and social norms affecting gender roles, their actual impact on workforce participation remains unclear. This study aims to analyze the impact of income, age, education, marital status, family size, culture, and social norms on the gender participation gap in the workforce in NTB. This explanatory research uses a survey sampling method, with 140 respondents. The data is analyzed using multiple linear regression to test and estimate the hypotheses. The hypothesis testing reveals that income significantly affects the gender participation gap in the workforce. However, age, education, marital status, family size, and the cultural and social norm control factors were not found to have a significant impact on the gap in NTB. Culture and social norms, although expected to influence gender roles and household work division, did not significantly contribute to the differences in work hours between men and women. The study concludes that while income plays a significant role in gender workforce participation in NTB, cultural and social norms are not as influential as anticipated. Further research may explore the deeper effects of these norms on gender roles and expectations in the workforce.

Analysis of High School Students' Perceptions of Continuing Studies at State Universities

2026-04-22T21:13:38+00:00

This research aims to analyze high school students' perceptions of continuing their studies at state universities based on internal and external factors. This research employed a survey approach involving Grade XII students from public and private high schools in Karawang Regency. The research instrument consisted of a questionnaire with 40 statement items covering internal and external indicators, supported by interviews with selected respondents. Data were analyzed using descriptive percentage analysis to determine the level of students' interest and the influencing factors. The results of the study indicate that both internal and external factors fall into the "very low" category, showing that students' interest in continuing to higher education is generally weak. Internal factors such as motivation, self-confidence, and career planning were found to be low, while external factors including family economic conditions, parental support, peer influence, and limited access to information significantly affect students' decisions. Interview findings also reveal that many students prefer to enter the workforce immediately after graduation to support their families financially, although some still aspire to pursue higher education in the future. In conclusion, students' low interest in continuing to higher education is influenced by a combination of internal and external factors, with economic conditions being the most dominant. Therefore, it is recommended that schools, the government, and relevant stakeholders strengthen guidance programs, provide access to scholarships, and raise awareness of the long-term benefits of higher education to encourage students to pursue further studies.

Evaluation of Hypertension Treatment in Patients Who Have Received mRNA-based Covid-19 Vaccines

2026-04-24T03:43:53+00:00

Hypertension remains one of the leading global public health problems and is a major risk factor for cardiovascular disease. The widespread implementation of COVID-19 vaccination, particularly mRNA-based vaccines, has raised concerns regarding potential cardiovascular effects, including transient blood pressure changes. This study aimed to evaluate hypertension treatment outcomes in patients who had received mRNA-based COVID-19 vaccines and to analyze the influence of sociodemographic factors on clinical outcomes. A quantitative analytic study with a retrospective cross-sectional design was conducted using electronic medical records from 400 adult hypertensive patients who received Pfizer or Moderna vaccines. Data included blood pressure measurements before and after vaccination, number of antihypertensive medications, comorbidities, and sociodemographic characteristics. Statistical analysis was performed using non-parametric tests. The results showed no statistically significant difference in the number of antihypertensive drugs before and after vaccination (median 2.00; p = 0.451). There were also no significant associations between sociodemographic variables and post-vaccination blood pressure, except a limited association with systolic blood pressure in patients with comorbidities. Overall, mRNA COVID-19 vaccination did not significantly affect antihypertensive therapy requirements or blood pressure control. These findings support the safety of mRNA vaccination in hypertensive patients, although continued monitoring, particularly of systolic blood pressure in patients with comorbid conditions, remains recommended.

Speech delay is one of the most common developmental issues in early childhood, affecting 5-10% of preschool children in Indonesia with an increasing trend annually. This study aims to identify internal and external factors influencing speech delay in children under 5 years old at YARSI Hospital. Using a quantitative observational analytic approach with a cross-sectional design, data were collected from 102 children diagnosed with speech delay through total sampling over a 6-month period. Results showed that speech delay was more prevalent in boys (69.6%) and children aged 49-59 months (31.4%). Internal factors identified include genetic and family history (29.4%), intelligence level, physical disability (15.7%), and prematurity (6.9%). External factors include parental education, parenting style with permissive pattern being dominant (44.1%), socioeconomic status with most families in low to medium categories (46.1% and 44.1%), gadget use, parental employment, and foreign language exposure (29.4%). This study concludes that speech delay is a multifactorial condition influenced by the interaction between internal biological factors and external environmental factors. From an Islamic perspective, children are an amanah from Allah SWT, and speech delay should be addressed through comprehensive efforts involving medical, educational, social, and spiritual approaches with patience and consistent stimulation.

The Effect of Depression Level on Quality of Life in the Elderly at Nursing Homes

2026-04-24T04:08:31+00:00

As individuals age, they experience a natural decline in physical and cognitive function, increasing their vulnerability to various health problems, including depression. This condition may lead to reduced cognitive ability, diminished physical functioning, social withdrawal, poor sleep quality, and an elevated risk of suicide. Depression is more prevalent among older adults residing in nursing homes compared to those living with their families, and has been shown to negatively affect nearly all dimensions of quality of life. In Islamic teachings, caring for the elderly is a moral and spiritual obligation that emphasizes respect, compassion, and the fulfillment of their rights. This study aims to analyze the effect of depression level on the quality of life of older adults living in nursing homes and to examine these findings from an Islamic perspective. A quantitative cross-sectional design was employed, involving 77 respondents selected through simple random sampling. Of these, 16 respondents experienced depression and 5 were identified as having poor quality of life. The chi-square test yielded a p-value of 0.000, indicating a statistically significant association between depression level and quality of life. These findings highlight the impact of depression on the well-being of older adults and underscore the importance of providing humane, person-centered care aligned with religious values.

Using a hedonic test, the results of the study are expected to show the optimal formulation of gluten-free dry noodles that have a significant increase in protein content without sacrificing texture quality and public acceptance. Based on the effectiveness test of the De Garmo method, the A2 treatment was selected as the best treatment with a total result value of 0.642.

Police–Government Collaboration in MSME Empowerment: Evidence from Bangka Belitung

2026-04-24T08:21:42+00:00

This study discusses the economic growth paradox without security in the Bangka Belitung Islands Province, where reported crimes have increased by 37.6 (1,566 to 2,155 cases) over the period between 2021 to 2023, despite the 12.8 growth in MSMEs amid an economic transition not based on tin mining. The study dwells on the police-local government cooperation in the empowerment of MSMEs as a Crime Prevention Through Social Development (CPSD) measure. Using qualitative case study research approach and interviewing the stakeholders of ABCGM (Academy, Business, Community, Government, Military/Police) by using in-depth interviews and focus groups, this study develops the Community-Based Empowerment Model (Model BBM). The results illustrate the multidimensional aspect of MSMEs in security, which constitutes surveillance networks, economic stabilization, social capital formation, and situational crime prevention. The BBM Model works out Bhabinkamtibmas (community police officers) as ecosystem orchestrators in five functions: assessment, bridging, capacity-building, governance, and monitoring. The paper is an addition to the theoretical synthesis of procedural justice developed by Tyler, community policing developed by Bayley and economic criminology, as it provides a practical road map of the 17,000 Indonesian island communities shifting to extractive ones.

The Effect of Cephalic Arch Stenosis Location on Angioplasty Success and Patency at 3 and 6 Months in Patients with Brachiocephalic Fistula

2026-05-01T10:44:56+00:00

Failure of maturation and stenosis are major obstacles to arteriovenous fistula patency in hemodialysis patients. The cephalic arch commonly develops vascular dysfunction and can be divided into four domains. However, no study in Indonesia has evaluated the effect of cephalic arch stenosis location on angioplasty outcomes. This study aimed to determine the relationship between the location of cephalic arch stenosis and angioplasty success, as well as 3- and 6-month patency in patients with brachiocephalic fistulas, and to identify influencing factors. This retrospective cohort study included 68 patients with cephalic arch stenosis and brachiocephalic fistulas treated in outpatient clinics or inpatient wards at Cipto Mangunkusumo Hospital (RSCM) from January 2022 to December 2024. Data were obtained from medical records. Bivariate analysis was performed using the Chi-square or Fisher’s exact test, and multivariate analysis was conducted using Firth logistic regression. The angioplasty success rate was 91.2%, with 3-month patency of 87.1% and 6-month patency of 66.7%. Multivariate analysis showed that stent use was significantly associated with reduced 3-month patency after angioplasty (OR 0.12; 95% CI 0.02–0.93; p = 0.042), and a cephalic arch insertion angle ≥60° was associated with decreased 6-month patency after angioplasty (OR 0.23; 95% CI 0.06–0.77; p = 0.017). Stenosis location, age, sex, degree and length of stenosis, cephalic arch insertion angle, number of balloons, balloon size, balloon pressure, balloon type, stent use, hypertension, and diabetes were not associated with residual stenosis or with 3- and 6-month patency after angioplasty.

2026-04-24T04:12:06+00:00

Sleeper bus services are becoming increasingly inseparable from the long-distance travel experience in Indonesia, especially on the Malang-Jakarta route. This study aims to analyze the characteristics of sleeper bus consumers as well as service strategies that can be applied to meet user expectations. With a survey and interview approach, data is collected from passengers with different demographic backgrounds. The results of the analysis show that the majority of users are private employees with an income above IDR 5,000,000 per month, who use this service for vacations, family visits, and business trips. While sleeper buses offer convenience, there are a number of gaps in terms of cleanliness, punctuality, and responsiveness of service. The study recommends several improvement strategies, including improved cleanliness of facilities, better time management, and interpersonal skills training for bus crews. By implementing this strategy, bus companies are expected to improve customer satisfaction and strengthen their position in the transportation market.

Analysis of Project Performance and the Selection of Mitigation Strategies for Fiscal Disruptions Due to Government Budget Relaxation Policies

2026-05-01T10:52:42+00:00

Changes in budget allocation mechanisms and delays in fund disbursement have adversely affected project schedules, cost efficiency, and cash flow stability. This study aims to quantitatively evaluate the impact of fiscal disruption on project performance using Earned Value Management (EVM) indicators—namely the Schedule Performance Index (SPI) and Cost Performance Index (CPI)—and to identify the most feasible managerial mitigation strategy under constrained fiscal conditions. The research adopts a quantitative-dominant mixed-methods approach utilizing secondary data derived from official project documents, including S-curves, progress reports, cash flow statements, and government fiscal policy regulations. Project performance is assessed through EVM, while financial conditions are evaluated using Net Cash Flow (NCF) and Net Profit (NP) analysis. Several alternative funding strategies are analyzed using Discounted Cash Flow (DCF) techniques such as Net Present Value (NPV), Internal Rate of Return (IRR), Discounted Payback Period (DPP), and Debt Service Coverage Ratio (DSCR). The alternatives are subsequently ranked using a Multi-Criteria Decision Making (MCDM) approach based on a Weighted Scoring Model (WSM). The results indicate that fiscal adjustment policies significantly deteriorated project performance, as reflected by an SPI of 0.669 and a CPI of 0.957 as of June 2025. Among the evaluated mitigation strategies—internal funding, external funding, partial PPP, and a combination of internal–external funding—the combined strategy yields the most balanced technical and financial performance. Although it does not generate the highest profit, this strategy demonstrates superior overall feasibility and resilience under fiscal pressure.

2026-04-24T03:43:47+00:00

This study explores the role of academic supervision conducted by school supervisors within the Merdeka Belajar paradigm and its contribution to improving high school students’ learning achievement in East Manggarai Regency, Nusa Tenggara Timur. Using a mixed-method approach with the CIPP evaluation model, this research combines quantitative and qualitative data to obtain comprehensive insights regarding the implementation, impact, and challenges of academic supervision. The findings reveal that academic supervision has been carried out systematically and contextually, beginning with needs analysis, collaborative planning, and implementation through coaching, mentoring, observation, and reflective dialogue. Supervision contributes to improving the quality of teaching practices, classroom management, teacher professionalism, student engagement, and the tendency of improved learning outcomes. Teachers also perceive academic supervision positively, acknowledging its role in strengthening planning, instructional strategies, and formative assessment. However, the study also identifies several constraints, including varied teacher understanding of Merdeka Belajar, limited facilities, administrative burden, uneven implementation, and insufficient follow-up support, resulting in learning achievements that have not yet been evenly improved across schools. Overall, academic supervision remains a strategic instrument to support the implementation of Merdeka Belajar and enhance student learning achievement, but it requires more consistent, contextual, and sustainable strengthening through improved mentoring, capacity building, and policy support.

Analysis of the Impact of the Mining Sector on Regional Competitiveness in West Nusa Tenggara Province

2026-04-24T04:37:41+00:00

The existence of mineral and coal resources in an area is often considered an advantage that can increase the competitiveness of the area. However, regions with large mining sector GDP do not always show high economic growth. For example, West Sumbawa Regency, which has a significant mining sector, only recorded an average economic growth rate of 3.19% between 2010 and 2023, placing it in the second lowest position in West Nusa Tenggara Province (NTB). This research aims to analyze the economic structure and sector shifts in each district in NTB using Location Quotient (LQ) and Shift Share analysis, as well as to form a Regional Competitiveness Index model with a Geographically and Temporally Weighted Regression (GTWR) approach. The results of the study show that the majority of districts in NTB have a base sector in the agricultural sector, except for West Lombok Regency in the transportation sector and West Sumbawa Regency in the mining sector. Sector shifts show different potentials, but the mining sector in areas that have not been massively exploited still has opportunities to be developed. The Regional Competitiveness Index model shows that the influence of the mining sector on competitiveness is not significant between regions with high and low mining sectors. In conclusion, excessive dependence on the mining sector can hinder economic growth and reduce regional competitiveness. It is important to maintain a balance between the development of the mining sector and other more sustainable sectors for stable and diversified economic growth.

Risk Management in Redesigning Main Dam for the Tiu Suntuk Dam Implementation

2026-05-01T10:45:05+00:00

The redesign of the Tiu Spara Dam main dam was carried out in response to changes in technical conditions and operational needs of the project, but this process has the potential to pose various risks that can affect the stability, safety, and performance of the dam. This study aims to identify risk indicators, analyze risk levels and priorities, and formulate risk control strategies in the redesign of the Tiu Suntuk Dam main dam. The method used is a descriptive quantitative approach based on ISO 31000:2018 risk management, with data collection through field observations, interviews, literature studies, and questionnaire dissemination to experienced respondents. Risk analysis was conducted using the Severity Index method to assess the probability and impact of the risk, which was subsequently mapped into a risk matrix. The results showed that the highest risk came from the technical aspects, namely changes in soil carrying capacity, availability of materials for new designs, and suitability of dam design with actual slope conditions, all of which fall under the category of extreme risk. Therefore, it is necessary to strengthen technical investigations, design adjustments, improve work quality control, and implement systematic and integrated risk management. This research is expected to be a reference in risk management in similar dam projects to improve structural safety and the sustainability of dam functions.

Analysis of the Potential Cost of Damage Due to Liquefaction on Two-Story Residential Buildings in North Jakarta

2026-04-27T03:53:20+00:00

This study is motivated by the high seismic activity in Indonesia due to the interaction of three major tectonic plates, as well as the geological conditions of coastal areas such as North Jakarta, which are dominated by soft, water-saturated alluvial soils prone to liquefaction. This phenomenon can lead to severe structural damage and significant economic losses, particularly for two-story residential buildings. This research aims to analyze the liquefaction potential and estimate the economic losses caused by building damage in North Jakarta. The study employed a quantitative descriptive approach using Standard Penetration Test (N-SPT) data from 26 drilling points. Key geotechnical parameters, including Cyclic Stress Ratio (CSR), Cyclic Resistance Ratio (CRR), Magnitude Scaling Factor (MSF), and Safety Factor (SF), were calculated. Earthquake acceleration (amax) was also analyzed using Donovan, McGuire, and Matuschka methods. The results indicate that liquefaction potential increases with earthquake magnitude, with critical conditions occurring at a magnitude of 5.5 Mw, where all points experience liquefaction in shallow layers. Cilincing and Ancol are identified as the most vulnerable areas due to low N-SPT values and shallow groundwater levels. The estimated total economic loss reaches IDR 4.734 trillion, with per capita losses ranging from IDR 3.4 million to IDR 6.3 million. In conclusion, North Jakarta faces high liquefaction risk with substantial economic impacts, highlighting the need for mitigation strategies in urban planning and structural design.

An Analysis of the Effects of Competence, Internal Locus of Control, and Work Culture on Employee Organizational Commitment: A Case Study at Kraton Regional General Hospital, Pekalongan Regency

2026-04-27T03:50:51+00:00

This study aims to analyze the effects of employee competence, internal locus of control, and work culture on organizational commitment at Kraton Regional General Hospital (Rumah Sakit Umum Daerah/RSUD Kraton), Pekalongan Regency, both partially and simultaneously. A quantitative approach with multiple linear regression analysis was employed. The study population comprised 232 employees of RSUD Kraton. Data were analyzed to measure the effect of each independent variable on organizational commitment. Internal locus of control was found to exert the most dominant influence on organizational commitment, with a regression coefficient (B) = 0.346, t = 11.097, p = 0.000. Employee competence also had a significant effect, with B = 0.245, t = 6.888, p = 0.000. Work culture, however, did not demonstrate a statistically significant effect, with B = 0.010, t = 0.246, p = 0.807 (p > 0.05). Simultaneously, the three variables jointly and significantly influenced organizational commitment. Among the predictors, internal locus of control emerged as the most dominant factor, followed by employee competence, both of which significantly affected organizational commitment. Competence was found to support the enhancement of employee engagement, whereas work culture, although positively directed, did not yield a statistically significant effect. These findings suggest that strengthening internal locus of control and developing employee competence are more effective strategies for enhancing organizational commitment at RSUD Kraton than improving work culture alone.

2026-04-24T07:47:58+00:00

The background of this study is to examine how transformational leadership and school climate influence teacher job satisfaction. This study aims to analyze the influence of transformational leadership and school climate variables on job satisfaction and analyze the influence of transformational leadership on school climate. The method in this study is a quantitative research type with an explanatory approach with data sources used in the form of numbers from survey results given to a number of samples. The results of this study are that there is a positive and significant influence between transformational leadership on job satisfaction, then there is a positive and significant influence between school climate on teacher job satisfaction, meaning that a mutually supportive school environment, and a principal who provides motivation can increase teacher job satisfaction. The results of descriptive analysis with a normality test on the transformational leadership variables of school principals using the one sample Kolmogorov Smirnov test, were obtained by Asymp.

Spheroidization and Its Effect on the Decrease in Mechanical Strength of Steel SA210 Gr. A1

2026-04-24T07:00:25+00:00

SA210 Gr. A1 is an important material used in piping systems and boiler components due to its high mechanical strength and resistance to high temperatures. However, long-term exposure to high temperatures can cause microstructural degradation through the spheroidization process, which results in a decrease in mechanical properties. This study aims to evaluate the effect of the spheroidization process on the mechanical strength and microstructure of SA210 steel Gr. A1. The methods used include spheroidization heat treatment at 660°C with time variations of 3, 10, and 100 hours, followed by Vickers hardness testing and tensile testing per ISO 6892-1. After 100 hours of spheroidization, ultimate tensile strength (UTS) decreased from ~51.5 to ~43.9 kgf/mm² (15% reduction), yield strength (YS) decreased from ~44.7 to ~28.4 kgf/mm² (36% reduction), and Vickers hardness decreased from ~169 to ~141 VHN (17% reduction). Elongation increased from 28% to 47% (68% increase), indicating significantly improved ductility at the cost of strength. Results show that spheroidization contributes to a decrease in tensile strength (UTS) and yield strength (YS), but increases the ductility (elongation) value and decreases the hardness of the material. This transformation makes the material more ductile, but at the cost of reduced mechanical durability.

Estimating the Need for Infiltration Wells to Support Groundwater Conservation and Surface Runoff Control in Enggal Subdistrict

2026-04-18T02:31:23+00:00

Urban areas frequently encounter environmental challenges such as the reduction of green open spaces, water shortages during the dry season, and water ponding during the rainy season. These problems are mainly caused by rapid urbanization and the expansion of impervious surfaces, which reduce natural infiltration capacity and increase surface runoff. As a result, groundwater recharge decreases while the potential for urban flooding becomes higher. Similar conditions are observed in Enggal District, located in the central area of Bandar Lampung City, Indonesia. Therefore, effective stormwater management strategies are required to mitigate surface runoff while improving groundwater conservation. This study aims to estimate the required number of infiltration wells needed to achieve zero run-off conditions in Enggal District. The study area covered approximately 2.80 km² and consists of six urban villages with a population of 24,611 in 2025 based on the Enggal District Report. Land-use analysis indicates that the area has a surface runoff coefficient of 0.55. Hydrological analysis was conducted using 20 years of rainfall data (2005–2024) to determine rainfall characteristics and runoff potential. The rainfall intensity analysis for a 10-year return period produced a peak discharge of 15.88 m³/s with a rainfall intensity of 37.23 mm/h. Several designs with 2 scenarios were developed by considering variations in infiltration well dimensions and land availability within the study area.

Optimization of Clean Water Supply Fulfillment Strategies at Water Treatment Plants in Industrial Areas

2026-04-22T21:15:33+00:00

The growing demand for clean water in industrial areas requires a reliable and sustainable supply system. However, water treatment plants are operating near capacity due to tenant growth, while high energy consumption, chemical cost fluctuations, and reactive maintenance increase operational and maintenance costs. This study aims to identify optimal strategies for meeting clean water demand in industrial water treatment plant service areas by optimizing operational costs and maintaining utility networks, including operations and maintenance (O&M) improvements, small capital expenditure (CAPEX) through supply chain management (SCM) implementation, and large CAPEX such as water treatment plant expansion or new construction. The research employed financial analysis based on present value (PV) and life cycle costing (LCC) with an analysis period of 20 years and a discount rate of 8%, based on historical water treatment plant operational data and investment estimates. Scenario and sensitivity analyses were conducted to strengthen decision-making. The results show that the O&M strategy is the most optimal and highest-priority strategy, as it provides the highest cumulative cost savings without upfront investment, with PV savings on OPEX and MEX of Rp230.07–677.51 million and Rp495.26 million in the moderate scenario, respectively. The small CAPEX strategy yielded a positive net present value (NPV) saving of IDR 51.48 million but was sensitive to initial investment levels and the degree of chemical cost savings. Meanwhile, the large CAPEX strategy has a total life cycle cost of IDR 57,415.00 million and is more appropriate as a medium- to long-term solution for increasing supply capacity and reliability.

The Role of Co-Creation in Visual Strategies for Social Campaigns on Food Waste Issues on Instagram: A Case Study of Foodcycle Indonesia

2026-04-22T21:14:36+00:00

Food waste is a significant issue in Indonesia affecting social, economic, and environmental sectors, requiring active public participation to address it. Although social media is widely used by organizations to raise awareness, audience engagement remains relatively low. This research aims to analyze the factors influencing audience engagement in FoodCycle Indonesia’s Instagram campaigns and develop a visual campaign strategy based on a co-creation approach. This research uses a mixed method approach with quantitative data collection through questionnaires to 166 Instagram audience respondents, as well as qualitative data through semi-structured interviews, Instagram content observation, and a co-creation process involving 10 selected participants. Quantitative data was analyzed descriptively, while qualitative data was analyzed using Miles and Huberman's interactive analysis model. The results show that even though the audience is interested in the issue of food waste and finds the FoodCycle Indonesia campaign message relatively clear, the level of audience interaction with the content is still moderate. Qualitative findings reveal a gap between the campaign's informative visual strategy and the audience's preference for more relevant, participatory, and contextual content. Through a co-creation approach, the audience is actively involved in the campaign's visual design process, resulting in content concepts that are more in line with the audience's needs and expectations. This study contributes by showing that the co-creation approach can be a relevant strategy in increasing audience engagement in social campaigns on social media, especially in the context of food waste issues in Indonesia.

Nurses' Perception of Career Development and Organizational Commitment and Its Components in Private Hospitals in Indonesia

Career development and organizational commitment are critical factors in improving nurses’ performance and retention in private hospitals. However, understanding how nurses perceive career growth and its influence on their commitment remains essential, particularly in the Indonesian healthcare context where workforce stability is a key concern. This study aims to explore nurses’ perceptions of career development and organizational commitment, as well as to examine how demographic factors influence these relationships in private hospitals in Indonesia. The study employs a mixed-method approach with an explanatory sequential design. It begins with quantitative analysis identifying career growth and demographic factors (age, gender, work experience, and work location) as predictors of organizational commitment. This is followed by a qualitative phase using virtual focus group discussions (FGDs) with 30 purposively selected nurses from private hospitals in North Sulawesi. Data were collected through semi-structured interviews and analyzed using Reflexive Thematic Analysis. The findings reveal three main themes: a positive work environment, emotional involvement at work, and challenges faced in the hospital. These results confirm that career development significantly influences nurses’ organizational commitment, supported by both quantitative and qualitative evidence. Career development plays a vital role in strengthening nurses’ commitment to their organizations. Hospitals are recommended to design structured career development and counseling programs to enhance employee engagement and long-term retention.
