Abstract

The increasing global prevalence of overweight and obesity, combined with limitations in conventional Body Mass Index (BMI) measurement practices, underscores the need for secure, automated, and cloud-integrated monitoring systems. Existing IoT-based BMI devices primarily focus on measurement accuracy but rarely integrate secure user authentication, longitudinal cloud tracking, usability validation, and formal technology readiness assessment within a single framework. This study aims to design, implement, and evaluate an IoT-based automatic BMI monitoring system equipped with RFID authentication and real-time cloud synchronization. The proposed system integrates an ESP32 microcontroller, ultrasonic and load-cell sensors, and an RFID PN532 module. Measurement data are transmitted to a Firebase Realtime Database and visualized via a web-based dashboard. Accuracy was evaluated using mean error analysis and linear regression (R²). Usability was assessed using the System Usability Scale (SUS) and End-User Satisfaction (ESU) questionnaire. Technology maturity was analyzed using the Technology Readiness Level (TRL) framework. Experimental testing with 25 participants demonstrated high measurement accuracy, with mean errors of 0.38% for height (R² = 0.952) and 0.35% for weight (R² = 0.9993). BMI computation showed strong agreement with manual calculation (R² = 0.9938). The average measurement cycle required 15.2 seconds. The system achieved a SUS score of 82.5 (Excellent), ESU score of 4.6/5 (Very Satisfied), and TRL 6 classification. The novelty of this study lies in integrating secure RFID authentication, cloud-based longitudinal monitoring, dual-layer usability evaluation, and formal TRL assessment into a single IoT BMI ecosystem.

Abstract

Developing a regional resilience index for natural disasters is essential for systematically monitoring resilience performance and supporting evidence-based policymaking. Strengthening regional resilience is particularly critical for West Java Province, given its high exposure and vulnerability to multiple hazards. This study aims to construct a comprehensive framework of regional disaster resilience indicators and to assess the level of resilience across the province. The research employs a Systematic Literature Review (SLR) and the PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) for multi-criteria analysis. Secondary data were obtained from Statistics of West Java Province, while the SLR was conducted using the Scopus database complemented by manual searches. A total of 77 selected articles yielded 22 principal indicators of regional disaster resilience, classified into five dimensions: economic, social, ecological, infrastructure, and institutional. The assessment reveals that several indicators—particularly within the ecological, infrastructure, and institutional dimensions—demonstrate relatively low performance across districts and cities. Based on 17 equally weighted indicators, the ranking results identify Cimahi City, Bandung City, and Cirebon City as the three most resilient regions in the province. Meanwhile, Tasikmalaya City, Cianjur City, and Indramayu City ranked lowest in terms of disaster resilience. These findings provide an empirical basis for stakeholders and policymakers to evaluate regional resilience capacity and formulate integrated action plans and targeted mitigation strategies to support sustainable and adaptive regional development.

Abstract

Fraud in public procurement remains a persistent governance problem despite the widespread implementation of digital systems in the public sector. Although prior studies confirm that e-procurement and e-government enhance transparency, empirical evidence integrating digital governance and organizational culture in explaining fraud detection effectiveness remains limited, particularly at the ministerial level in developing countries. This study aims to examine the impact of e-procurement and e-government on fraud detection and to analyze the moderating role of BerAKHLAK organizational culture within the Indonesian Ministry of Immigration and Corrections. This research employs a quantitative approach using survey data collected from 320 procurement and budget officials across 33 provinces in 2024-2025. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) to evaluate both direct and moderating effects. The results indicate that e-procurement (β=0,451; p<0,001) and e-government (β=0,357; p<0,001) have positive and significant effects on fraud detection. Furthermore, BerAKHLAK organizational culture significantly strengthens the influence of both e-procurement (β = 0,307, p<0,001) and e-government (β = 0,315, p < 0,001). The structural model explains 63,6% of the variance in fraud detection, demonstrating substantial explanatory power. This study offers novelty by developing an integrated moderated model that positions organizational culture as a contextual enhancer of digital fraud control mechanisms. The findings extend Agency Theory, the Theory of Planned Behavior, and fraud hexagon theory within a digital governance context. Practically, the results highlight that technological sophistication alone is insufficient; effective fraud detection requires the simultaneous strengthening of ethical organizational values to ensure sustainable and accountable public governance.

Abstract

Non-tax state revenue (NTSR) strengthens Indonesia’s fiscal capacity; however, research on governance mechanisms for service-based NTSR optimization, especially the Ministry of Finance's role, remains scarce. This study fills this gap by exploring fiscal supervision's moderating effect on the NTSR management-revenue optimization link. A qualitative systematic literature review (SLR) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework synthesizes 28 articles (2010–2025) and relevant reports. Thematic content analysis identifies patterns linking planning accuracy, service execution, governance quality, and supervisory mechanisms to revenue performance. The findings show that NTSR optimization is driven by integrated managerial functions (planning, actuating, and controlling), with realistic targets and effective service delivery boosting revenue. However, these factors alone do not ensure optimal outcomes. Fiscal supervision moderate governance by enhancing accountability, reducing information asymmetry, improving internal controls, and ensuring compliance across ministries. Effective supervision amplifies the impact of planning and execution on NTSR optimization, supporting sustainable revenue. This study uniquely conceptualizes supervision as a moderating institutional mechanism in service-based NTSR governance. It contributes to public financial management and revenue governance literature by integrating state revenue theory and managerial function perspectives into a unified model. Practically, the findings offer policy insights for adaptive, performance-oriented NTSR supervisory systems. This study is limited to service-based NTSR and qualitative synthesis; future research should use quantitative methods to test the moderating framework across broader NTSR sectors.

Abstract

Non-Tax Revenue (NTR) from the coal sector constitutes an important component of fiscal resources in resource-dependent economies. However, existing studies tend to examine tariff policy and digitalization as separate instruments, with limited synthesis on how their interaction shapes revenue optimization within extractive governance frameworks. This study aims to address this gap by systematically reviewing the literature on the role of tariff policy and digital governance in optimizing coal-sector NTR. This study employs a non-empirical qualitative SLR. Relevant national and international journal articles, policy reports, and academic publications published within the last decade were identified through structured database searches and screened using predefined inclusion and exclusion criteria. The selected literature was analyzed using narrative and thematic synthesis to identify recurring patterns, governance mechanisms, and conceptual linkages related to NTR optimization. The results indicate that tariff policy remains a central fiscal instrument in coal-sector NTR management, particularly when tariff structures are adaptive, transparent, and aligned with administrative capacity. The literature also shows that digitalization enhances NTR management indirectly by improving administrative efficiency, data accuracy, compliance assurance, and inter-agency coordination. Importantly, the findings suggest that digitalization alone is insufficient to optimize NTR outcomes without coherent institutional frameworks and effective governance coordination. The integrated synthesis reveals that tariff policy and digitalization are mutually reinforcing when implemented in a coordinated manner. Digital governance mechanisms strengthen the credibility and enforceability of tariff policy, while sound tariff design provides the fiscal foundation for effective digital implementation. This interaction constitutes the main conceptual contribution of the study.

Abstract

The rapid growth of digital media exposure has transformed adolescents’ daily interactions, particularly through online gaming. While prior studies have explored gaming and aggression, limited research has specifically examined verbal aggressive behavior within Junior High School settings. This study investigates the relationship between online game usage and verbal aggressive behavior among adolescents in a Junior High School context and identifies its educational implications for school-based behavior management. A quantitative correlational design with a cross-sectional approach was employed. The participants consisted of 60 eighth-grade students at a Junior High School during the 2024/2025 academic year. Data were collected using validated Likert-scale questionnaires measuring online game usage intensity and verbal aggressive behavior. Instrument validity was confirmed using Corrected Item Total Correlation, and reliability analysis yielded Cronbach’s Alpha coefficients of 0.898 (online game usage) and 0.880 (verbal aggressive behavior). Data were analyzed using the Pearson Product Moment correlation test at a significance level of 0.05. The analysis revealed a moderate and statistically significant positive correlation between online game usage and verbal aggressive behavior (r = 0.534, p < 0.05). The findings indicate that higher gaming intensity is associated with increased tendencies toward verbal aggression, including shouting, arguing, and using harsh language. This study contributes novelty by specifically focusing on verbal aggression in Junior High School adolescents within the context of digital media exposure. The results suggest that online gaming intensity is a meaningful predictor of school-based behavior patterns.

Abstract

Dairy products are known for their non-cariogenic properties and have even been reported to inhibit the attachment of cariogenic bacteria such as Streptococcus spp. on dental plaque. Dangke, a traditional dairy product from Enrekang, South Sulawesi, with a high protein content of up to 17.20%, dangke is considered a non-cariogenic food. This study aimed to evaluate the in vitro efficacy of Dangke in reducing Streptococcus levels in dental plaque. The evaluation of Dangke implicates the use of traditional dairy products in oral health. This quasi-experimental study used a post-test-only control-group design with 15 subjects selected via simple random sampling. Subjects were divided into two groups: a treatment group that consumed Dangke and a control group that consumed cheddar cheese. Plaque samples were collected twice from each subject—immediately after consumption (T1) and two hours later (T2)—resulting in 30 samples per group. The Streptococcus colony counts were analyzed at the Microbiology Laboratory, Faculty of Medicine, Hasanuddin University. At T1, the mean colony counts were 19.44 CFU/mL for the Dangke group and 31.56 CFU/mL for the Cheddar group. At T2, the counts were 2.44 and 27.56 CFU/mL, respectively. A statistically significant reduction was observed in the Dangke group (p = 0.028), while no significant change was seen in the Cheddar group (p = 0.746). Dangke demonstrated a significant antimicrobial effect against Streptococcus in dental plaque and may serve as a natural cariostatic agent, providing new insights into the potential of local food products for caries prevention.

Abstract

Although the macroeconomic determinants of growth are studied at length, there is still a lack of study on many aspects of the BRICS, which now includes the new members Egypt, Ethiopia, Iran, Saudi Arabia, the UAE, and Indonesia, especially about the simultaneous consideration of unemployment along with FDI, trade openness, and inflation in a single panel model. The objective of this paper is to investigate the short- and long-run influence on GDP growth by accounting for heterogeneity within this community. Method: Quantitative panel data analysis employing Panel ARDL with PMG estimator on secondary annual data (1991–2023) of 11 BRICS countries obtained from World Bank World Development Indicators. While FDI is positive and significant in the long run, unemployment is negative and significant (-0.217, p=0.008). Trade openness and Inflation are positive but not statistically significant. In the short run, unemployment is negative (-1.528, p=0.002); the error-correction term is -0.681 (p < 0.001), implying that 68% of the adjustment occurs annually. FDI and unemployment are identified as major long-run determinants, with rapid equilibrium adjustment. The innovation lies in the extended BRICS panel and the more recent disclosure of more potent effects of unemployment on structural turns. To this end, policies should be oriented toward promoting FDI and reducing unemployment to ensure sustained and inclusive growth, and institutional improvements would further enhance the gains from trade.

Abstract

As schools rapidly adopt Education Management Information Systems (EMIS), data-driven decision-making, and technology-enhanced instruction, there is growing interest in understanding how digital education management shapes students’ readiness for Industry 4.0. This study aims to clarify the systemic role of digitalization in developing students’ cognitive, digital, and socio-adaptive competencies by proposing a comprehensive evaluation framework. A qualitative, theory-driven design was employed, synthesizing literature on digital education management, evaluation models, and readiness theory. The study developed the Adaptive-Integrated Readiness Index (AIRI), integrating concepts from CIPP, TPACK, and existing digital readiness indices to assess the combined influence of infrastructure, managerial processes, technological integration, instructional innovation, and institutional policies on multidimensional student readiness. Analysis indicates that current digitalization initiatives are fragmented and that prevailing evaluation approaches often focus narrowly on technology tools or user acceptance. AIRI demonstrates that students’ readiness is best understood as a dynamic capability shaped by interconnected digital management processes rather than isolated interventions. By reconceptualizing readiness as an emergent property of integrated digital management, AIRI provides policymakers and practitioners with a diagnostic framework to assess the impact of digital initiatives, identify areas for improvement, and align technology investments with Industry 4.0–oriented learning outcomes. The study highlights the importance of systemic evaluation to ensure that digitalization efforts translate into meaningful, holistic student competencies.

Abstract

Technological advancement is now a part of everyday human existence. A good example of this is the field of education. It is now widely understood that learning must be adaptable and accessible at all times in order to meet the needs of diverse learners. This level of flexibility is provided by the Blended instruction paradigm, which mixes in-person and online instruction. This study aims to determine the effect of the blended learning model assisted by QR codes on student learning outcomes in the Matrix Algebra course. The study took a quantitative approach and used a quasi-experimental design with one group pretest-posttest. The study included 34 Mathematics Education Program students from Universitas Muhammadiyah Metro in Indonesia. The researchers created and administered a series of verified and reliable (0.86) test instruments to the students, then evaluated the results with a paired sample t-test. Based on the findings, it is possible to conclude that implementing the blended learning approach with QR codes had a considerable favorable impact on students' academic progress in the Matrix Algebra course. This research innovatively proposes a blended learning framework involving qualitative data and advanced theoretical mathematics with the use of QR codes. The research shows that a blended learning framework with integrated QR codes can be effective and useful in improving university students' conceptual understanding and learning outcomes in mathematics courses.
