The current implementation of adaptive behavior training for students at risk of mild intellectual disabilities at SMP Negeri 3 Kaubun remains suboptimal due to the absence of specialized support teachers. This study was motivated by the importance of adaptive behavior training in enabling students with mild intellectual disabilities to function more independently in their daily lives within the school environment. The study examined how the school fostered adaptive behavior through the role of homeroom teachers in addressing students’ cognitive and social limitations. A qualitative case study approach was employed. Data were collected from three key informants—the parents, the homeroom teacher, and the school principal—through observation, in-depth interviews, and document analysis. Data were analyzed using an interactive qualitative analysis model comprising data collection, data reduction, data display, and conclusion drawing. The findings revealed three main results: students experienced difficulties in processing complex explanations and demonstrated limited social interaction; homeroom teachers implemented seven adaptive strategies, including classroom responsibility agreements, attendance-based rewards, and empathetic communication; and parents reported that their children interacted less socially at home but consistently completed their homework. The study concluded that homeroom teachers played a crucial role in fostering adaptive behavior through structured routines and active school–parent collaboration. However, the lack of inclusive educational infrastructure, limited specialized training, and persistent social stigma remained significant barriers requiring systematic policy intervention.

Annisa Camalia Anjani, Bambang Iskandriawan — Thu, 06 Aug 2026 00:00:00 +0700

Private hospitals in Indonesia face a dual challenge: serving a high proportion of BPJS patients while maintaining organizational sustainability through services for non-BPJS patients. However, negative public perceptions of the BPJS system may affect a hospital's brand image and obscure its differentiation in the minds of consumers. This study formulates a differentiation-based brand image strategy to increase non-BPJS patient utilization at Private Hospital X in Jember—a Type C hospital with approximately 80% of its patients covered by BPJS—using the Double Diamond Design Thinking framework. Employing a qualitative case study approach, data were collected from internal stakeholders through in-depth interviews, digital observation, and document analysis. Thematic analysis identified key themes related to determinants of hospital selection, internal challenges in brand image management, and potential differentiation strategies. Strategic recommendations were developed through market segmentation, the formulation of Points-of-Parity (POP) and Points-of-Difference (POD), a desired brand image framework, and the implementation of the 7Ps Marketing Mix. The findings reveal that non-BPJS patients are predominantly price-sensitive consumers who prioritize value for money, while the hospital's internal challenges include limited human resource competencies and an unstructured branding system. The study concludes that Hospital X possesses strong functional and symbolic advantages, including humanistic service, affordable pricing, and a wide range of non-BPJS services, but requires a more strategic communication approach to strengthen its differentiation. This research contributes an applied strategic framework to support managerial decision-making for the development of non-BPJS services within the field of Strategic Brand Management.

The Effectiveness of Contract Control for the Procurement of Goods and Services at the Secretariat General of the Constitutional Court

Muhammad Rizki, R. Luki Karunia — Thu, 06 Aug 2026 00:00:00 +0700

Contract control in government procurement is a critical determinant of the quality of public expenditure. However, recurring audit findings related to volume shortages, overpayments, and non-compliance indicate persistent weaknesses in contract control across Indonesian public institutions. This study aims to analyze the effectiveness of contract control in the procurement of goods and services at the Secretariat General of the Constitutional Court. Contract control is essential for ensuring that procurement activities are conducted in accordance with applicable regulations while meeting requirements related to time, quality, cost, and organizational objectives. In practice, effective contract control extends beyond administrative compliance to include monitoring contract implementation, verifying compliance with technical specifications, mitigating risks, and addressing issues that arise during contract execution. This study employed a qualitative descriptive approach, with data collected through observation, interviews, and document analysis. The analysis examined the effectiveness of contract control throughout the procurement process, including the planning, implementation, monitoring, evaluation, and contract completion stages. The findings indicate that effective contract control is strongly influenced by comprehensive planning, competent human resources, effective inter-unit coordination, regulatory compliance, and the use of a structured monitoring system. Well-implemented contract control minimizes project delays, non-compliance with technical specifications, contractual disputes, and the risk of financial losses to the state. Therefore, contract control within the procurement of goods and services at the Secretariat General of the Constitutional Court should be implemented consistently, transparently, and accountably to support the principles of good governance.

The Effect of Performance on Reinsurance Decisions of Indonesian General Insurance Companies: An Empirical Review of the Pandemic and Post Pandemic Period

Helena Nadine Hapsari, Lukman Hanif Arbi — Thu, 06 Aug 2026 00:00:00 +0700

This research aims to analyze the effect of ROE on REINS of general insurance companies in Indonesia, comparing the pandemic period (2020–2022) and the post-pandemic period (2023–2024). Using panel data from 50 companies over the 2020–2024 period (250 observations), this study employs three empirical models: Model 1 (2SLS two-way fixed effect with insurance leverage as instrument), Model 2 (OLS one-way fixed effect with contemporaneous ROE), and Model 3 (OLS one-way fixed effect with a one-period lag of ROE). Estimation results show that in Model 1 and Model 2, ROE has no significant effect on REINS. In Model 3, the lag of ROE has a positive coefficient (0.01967) and is significant at the 10% level (p = 0.074), which does not support the underinvestment hypothesis. Financial leverage consistently shows a positive effect, while premium growth consistently shows a negative effect. Comparative period analysis reveals that during the pandemic, the lag of ROE is not significant, whereas in the post-pandemic period, the lag of ROE becomes positive (0.199) and significant (p = 0.009). The Chow test yields a p-value of 0.05758, significant at the 10% level. Model 3 is selected as the main model as it better reflects the real-world decision-making process. This study concludes that the effect of ROE on REINS in Indonesia differs from previous findings, and that the relationship pattern changed after the pandemic. These findings have implications for insurance company management and regulators in formulating reinsurance strategies based on past performance, leverage, and premium growth.

This research aims to analyze the tendency of growth mindset and fixed mindset and their relationship with the chemistry learning process in the perspective of educational psychology. The research used a mixed method approach, namely a descriptive quantitative and qualitative approach with a total sampling technique for 34 students of SMAS Bhaktyarsa Maumere. The instrument used was a Likert scale-based mindset questionnaire that has been tested for validity and reliability. Data analysis was carried out through simple descriptive and correlational statistics. The results showed that 55.9% of students were in the fixed mindset category and 44.1% in the growth mindset category. The validity test showed most of the instrument items were feasible for use in the study, while reliability was in the category of sufficient. The findings indicate a tendency to have a positive relationship between growth mindsets and the quality of the chemistry learning process, especially in the aspects of perseverance, response to difficulties, and learning motivation. However, the strength of the relationship obtained in this study has not fully demonstrated a causally significant influence, so further research with a stronger inferential design is needed.

Optimization of Preventive Replacement of Critical Components in the Komatsu PC2000-8 Excavator to Minimize Downtime at PT XYZ

Imam Nur Soleh, Mokh Suef — Thu, 06 Aug 2026 00:00:00 +0700

The availability of primary loading equipment, particularly the Komatsu PC2000-8 excavator, is a key determinant of operational efficiency in open-pit mining. Failures of critical components directly affect downtime, maintenance costs, and key performance indicators, including physical availability (PA), mean time between failures (MTBF), and mean time to repair (MTTR). Current preventive maintenance practices, which largely follow generic original equipment manufacturer (OEM) replacement intervals, often fail to prevent actual breakdowns, highlighting the need to optimize preventive replacement intervals based on cost and downtime minimization. This study aims to determine the optimal preventive replacement intervals for the critical components of the Komatsu PC2000-8 excavator to minimize downtime and maintenance costs while improving equipment availability. The study employed a quantitative comparative optimization approach. Critical components were identified using a Pareto diagram based on failure frequency and cumulative downtime. Reliability analysis was performed by selecting the most appropriate time-between-failures distribution using Relyence Weibull software to estimate the distribution parameters. Reliability, hazard rate, MTBF, and cost analyses comparing preventive and corrective replacement—including spare parts, labor, supporting equipment, and lost production or contractual implications—were subsequently performed. An Age Replacement policy was then optimized to determine replacement intervals that minimized the long-run average cost per unit time while satisfying equipment availability constraints. The results indicated that the optimal preventive replacement intervals based on cost minimization were 11,545 hours for the Boom Cylinder, 16,820 hours for the Turbocharger, 7,366 hours for the Water Pump, 20,026 hours for the Final Drive, and 19,624 hours for the Radiator.

Impact of Net Zero Emission 2060 Initiatives to the Commercial Electric Vehicle Adoption in Indonesia: A System Dynamic Model Approach

Abdu Robbi — Thu, 06 Aug 2026 00:00:00 +0700

Indonesia has committed to achieving Net Zero Emissions (NZE) by 2060, with transport electrification identified as one of the key mitigation strategies. This study investigates the impact of government policies on commercial electric vehicle adoption, particularly electric buses, in Indonesia using a System Dynamics approach. A simulation model was developed in Vensim® PLE 10.3.1 based on Causal Loop Diagrams (CLDs) and Stock-and-Flow Diagrams (SFDs) to evaluate 17 policy scenarios over the 2026–2060 period. The scenarios represent combinations of value-added tax (VAT) incentives, fuel price reforms, and electricity tariff policies under Indonesia’s Enhanced Nationally Determined Contribution (ENDC). The findings indicate that, under business-as-usual conditions, commercial electric bus adoption remains limited, reaching only approximately 8,925 units by 2060. The Total Cost of Ownership (TCO) is identified as the primary determinant of adoption, with fuel prices exerting the strongest influence on market competitiveness. Among the evaluated scenarios, the combination of a 10% VAT incentive and fuel subsidy removal produces the best outcome, enabling the market to reach the projected saturation level of 132,000 electric buses while expanding domestic manufacturing capacity to more than 20,500 units annually. This scenario is also projected to reduce approximately 8,785 Gg CO₂ emissions in 2060, contributing 18–22% of the annual emissions reduction target under Indonesia’s Second Nationally Determined Contribution (SNDC). The results highlight that fuel price reform is the most effective policy instrument, while VAT incentives and affordable electricity tariffs play complementary roles in accelerating commercial electric vehicle adoption.

The Relationship Between Energy Intake, Protein Intake, and the Albumin-To Globulin Ratio and Stunting in Toddlers Aged 24–59 Months

Hafsha Rizki — Thu, 06 Aug 2026 00:00:00 +0700

Stunting remains a global public health problem characterized by chronic growth failure resulting from long-term undernutrition and recurrent infections. This study aims to analyze the relationship between energy intake, protein intake, and the albumin-to-globulin (A/G) ratio and the incidence of stunting in toddlers aged 24–59 months. The study synthesized evidence from 18 expert-validated variables derived from the literature in the fields of nutrition, public health, and immunometabolism. Energy and protein intake were assessed alongside serum biomarkers, including albumin, globulin, and the A/G ratio, while stunting status was determined based on the Height-for-Age Z-score (HAZ) according to World Health Organization (WHO) standards. The literature review findings demonstrated that low energy and protein intake, together with a decreased A/G ratio, were significantly associated with the incidence of stunting. These findings indicate that inflammatory and metabolic imbalances, as reflected by serum protein biomarkers, play an important role in growth disorders in addition to inadequate nutritional intake. Stunting is not solely caused by an energy deficit but also involves complex biological mechanisms, including chronic inflammation and disturbances in protein metabolism. This study contributes to a more integrative understanding of stunting by combining nutritional and biomolecular perspectives while supporting the development of more precise and multidimensional intervention strategies.
