Design and Evaluation of a Flutter Node.js Mongo DB System for Hospital Nutritional Inventory Auditing

Raihan Muflih — 2026-09-09

Manual auditing of hospital nutritional supplies often results in delays, transcription errors, and discrepancies between physical stock and system records. This study designed and evaluated a mobile-cloud inventory auditing system for the nutritional installation at RSUD Kraton Pekalongan. The system was developed using the Waterfall Software Development Life Cycle (SDLC) model and implemented with a Flutter mobile application, a Node.js backend, a MongoDB database, and Firebase-based data synchronization. Actual operational data from a one-month deployment in April 2025 were used to evaluate the system against the previous manual workflow. The results showed an input accuracy of 98.47% (1,226 valid entries out of 1,245), a 90% reduction in inventory discrepancies, and an 80% reduction in auditing time, from 4.5 hours to 0.9 hours per section. Furthermore, network latency evaluation showed an average optimized payload ingestion time of 0.8 seconds under stable connectivity, supported by a low database input/output (I/O) footprint of 310.91 B/s for inbound traffic. These findings indicate that the proposed system substantially improved data consistency, reduced the burden of manual transcription, and accelerated hospital logistics auditing without requiring excessive network bandwidth. The study contributes a validated implementation model for mobile-cloud inventory management in healthcare settings and provides a practical foundation for future predictive inventory planning.

Analysis of the Impact of Internal and External Factors on the Financial Performance of Energy Subsector Maritime Transport Companies in ASEAN (2020–2024)

Astrianto Astrianto — 2026-09-09

Maritime transportation supports energy distribution and international trade across ASEAN; however, its financial performance is exposed to both corporate conditions and external market volatility. This study aims to examine the effects of liquidity, capital structure, asset efficiency, firm size, growth, global energy prices, and freight rates on the financial performance of energy-subsector maritime transportation companies in ASEAN during 2020–2024. A quantitative explanatory research design was employed using secondary data obtained from S&P Capital IQ, the IMF Global Price of Energy Index accessed through FRED, and the Baltic Dirty Tanker Index. Purposive sampling was used to select 43 listed companies, resulting in 215 firm-year observations, of which 172 were included in the regression analysis because growth calculations required lagged data. Panel data regression was conducted using R software, supported by the Chow test, Hausman test, and Breusch–Pagan Lagrange Multiplier test, with firm-clustered robust standard errors applied to address potential heteroskedasticity and within-firm correlation. The fixed-effects model results indicate that all internal and external variables simultaneously have a significant effect on operating return on assets. Partially, only total asset turnover has a positive and significant effect, whereas liquidity, leverage, firm size, growth, energy prices, and freight rates do not show statistically significant effects. These findings indicate that efficient asset utilization, particularly fleet productivity, is the primary determinant of financial performance. Therefore, companies should prioritize asset optimization while strengthening financial management and external risk mitigation strategies.

Assessment of Building Damage Levels and Methods to Accelerate the Rehabilitation of Madrasah Schools in North Lombok Regency

Faried Ma’ruf — 2026-09-05

North Lombok Regency remains vulnerable to earthquakes, and damage to madrasah buildings continues to disrupt safe learning environments. This study aimed to assess the level of building damage and formulate priority strategies for accelerating madrasah rehabilitation in the region. A mixed-methods approach was applied to 12 madrasahs comprising 65 buildings. Data were collected through visual assessments of structural, architectural, and utility components based on Circular Letter No. 47/SE/DC/2020. The findings were analyzed using Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, Internal Factor Analysis Summary (IFAS), External Factor Analysis Summary (EFAS), and the Analytic Network Process (ANP) using Super Decisions 2.10. The results showed that 42 buildings (64.62%) were slightly damaged, nine buildings (13.85%) were moderately damaged, and 14 buildings (21.54%) were severely damaged. IFAS and EFAS scores of 0.80 and 0.25, respectively, positioned the rehabilitation strategy in Quadrant I, indicating an aggressive strategic position. The ANP results ranked risk mitigation and prevention of structural failure as the leading strategy (14.87%), followed by industrialized earthquake-resistant construction using modular or prefabricated methods (13.34%). Kendall’s coefficient of concordance reached 1.00, indicating perfect agreement among experts. The study concluded that rehabilitation efforts should prioritize structural safety, earthquake resistance, and accelerated construction processes while supporting administrative efficiency, budget utilization, and cost-effective contracting strategies.

Symbolic Interaction Communication of Traditional Games in Yogyakarta Palace Culture

Ratih Pertiwi — 2026-09-07

Traditional games constitute living cultural heritage that transmits social values, collective memory, and cultural identity; however, their meanings are increasingly threatened by modernization and digitally oriented leisure activities. This study aimed to analyze symbolic interactions in traditional games within the Ngayogyakarta Hadiningrat Palace, identify the meanings attributed to their symbols by abdi dalem, and explain their role in sustaining Javanese culture. The study employed a qualitative design combining phenomenology and communication ethnography. Data were collected through participant observation, in-depth interviews with purposively selected abdi dalem, and documentation, then analyzed through data reduction, data presentation, conclusion drawing, and source, theoretical, and methodological triangulation. The findings revealed that symbolic interactions developed through Mead’s interconnected concepts of mind, self, and society. Game forms, numbers, colors, movements, turns, and customary rules functioned as significant symbols conveying ethical, social, philosophical, and spiritual meanings. Traditional games also facilitated role-taking, value transmission, social cohesion, and the reinforcement of cultural identity. The discussion demonstrates that abdi dalem act simultaneously as players and interpreters who continually negotiate shared meanings within palace norms. Therefore, traditional games are not merely recreational activities but also living communication systems that preserve Javanese values and support intergenerational cultural continuity within contemporary society amid rapidly changing social conditions.
