Three-phase induction motors are essential components in industrial cooling systems that require reliable overcurrent protection to maintain operational continuity and prevent equipment damage. In the Cooling Tower Pump panel at PT DongJin Indonesia, a limitation was identified where the terminal of the Electronic Overcurrent Relay (EOCR) could not accommodate the 50 mm² power cable, preventing direct current measurement. This study aims to analyze the effectiveness of integrating a 200:5 A Current Transformer (CT) with the EOCR as an adaptive protection solution that is both safe and efficient. The research employs a case study approach through field observation, motor current measurement using a Fluke 303 Clamp Meter, and descriptive analysis of the recorded data. The results indicate that the three motors operate under stable load conditions, with current values ranging from 236.7 A to 275.7 A, while the secondary current detected by the EOCR ranges from 3.7 A to 3.9 A, consistent with the CT transformation ratio. During the starting phase, the current surged to 600.4 A without causing false tripping, demonstrating that the EOCR effectively distinguishes temporary inrush current from actual fault conditions. Therefore, the integration of CT–EOCR is proven to enhance measurement safety, maintain motor operational stability, and support efficient system maintenance in industrial environments.

This research benchmarks multiple machine learning (ML) algorithms for large-scale loan default prediction using a real-world dataset of 255,000 borrower records, where default cases represent only ~9–12% of total observations. The study addresses the persistent gap in comparative analyses of ML models that balance predictive accuracy, interpretability, and computational efficiency for credit risk assessment. Six algorithmic families were evaluated Logistic Regression, Random Forest, XGBoost, LightGBM, CatBoost, Artificial Neural Networks (ANN), and Stacked Ensemble—using standardized preprocessing, hybrid imbalance handling (SMOTE, class weighting, under-sampling), and comprehensive evaluation metrics (AUC, F1, Recall, Precision, PR-AUC, and Brier Score). Empirical results show Logistic Regression achieved the highest AUC of 0.732, outperforming nonlinear models under the baseline configuration, while LightGBM attained perfect recall (1.0) but low precision (0.116), indicating over-prediction of defaults. Gradient boosting models demonstrated robust calibration (Brier ≈ 0.114–0.116) and the best computational efficiency, with LightGBM showing the fastest training and lowest memory use. CatBoost exhibited strong recall but the slowest computation, and ANN underperformed on tabular data (AUC ≈ 0.56). The Stacked Ensemble delivered balanced results with AUC = 0.664 and improved overall stability. These findings confirm that boosting-based models, particularly LightGBM and CatBoost, offer superior scalability and calibration, whereas Logistic Regression remains a valuable interpretable baseline. The study concludes that effective default prediction requires integrating rebalancing, calibration, and threshold optimization to enhance recall and operational deployment reliability in large-scale credit ecosystems.

The PESIAR Program (Petakan, Sisir, Advokasi, dan Registrasi Map, Screen, Advocate, and Register) is an operational instrument of BPJS Kesehatan designed to accelerate the achievement of Universal Health Coverage (UHC) by increasing National Health Insurance (JKN) membership at the local level. However, the effectiveness of this program’s implementation is strongly determined by the institutional capacity and configuration that support it. This article aims to reposition institutional determination not only as a factor influencing program effectiveness, but as a model of administrative governance in achieving UHC. The study uses a mixed methods approach with a sequential explanatory design. Quantitative data were obtained through a survey of PESIAR Agents in Semarang City, while qualitative data were collected through open-ended questionnaires and interviews. The results show a strong, positive relationship between institutional determination and the effectiveness of the PESIAR Program. Qualitative findings further clarify that issues of program effectiveness largely originate from institutional capacity, the quality of cross-sector coordination, and the role of PESIAR Agents as field implementers. This study concludes that institutional determination deserves to be positioned as an administrative governance model for the PESIAR Program in promoting the achievement of UHC at the local level.

This research aims to design an Information Systems and Information Technology (IS/IT) strategic plan for Wyndham OPI Hotel Palembang to support operational efficiency and enhance the quality of five-star hotel services. The study applies the Ward and Peppard framework, supported by analytical methods including Value Chain,PEST,SWOT,Critical Success Factors (CSF), MOST and McFarlan Strategic Grid. Through these approaches, the current IS/IT condition, challenges, and opportunities for digital system development within the hotel environment were mapped. The analysis reveals that although the hotel has implemented technologies such as SiteMinder and the Rhapsody management system, there is a need to improve self-service check-in capabilities, strengthen IT infrastructure, and maximize digital technology utilization. The proposed strategy recommends the development of an integrated self check-in system, enhancement of network infrastructure, and employee training through an LMS platform. This strategic plan is expected to support the hotel’s digital transformation to remain competitive in the modern hospitality industry.

This study aims to analyze the implementation of the Free Nutritious Meal Program through a collaborative governance framework in Kendal Regency using a mixed-methods approach with a convergent parallel design. Quantitative data collected from 34 respondents were analyzed using descriptive statistics and Pearson correlation analysis, while qualitative data obtained from five key informants were analyzed thematically. The results reveal very strong and statistically significant correlations (p < 0.001) among cross-sectoral coordination, stakeholder roles, community participation, and accountability–transparency, indicating that collaborative synergy is a decisive factor in successful policy implementation. The Kruskal–Wallis test indicates consensus across professional groups (p> 0.05). However, qualitative findings uncover a paradox of coordination without communication: implementers internalize coordination as a functional operational reality, while beneficiaries experience informational alienation. The resulting collaborative configuration can be characterized as technocratic–instrumentalist—technically effective yet weak in terms of social legitimacy. This study underscores that implementing social policy requires collaborative governance that is not only coordinative but also communicative and deliberative. Policy implications include strengthening dialogic public communication, transforming consultative participation into deliberative engagement, and promoting participatory transparency to foster shared understanding between bureaucratic systems and program beneficiaries.

This study aims to describe the form of multi-stakeholder collaboration in the management of the Bojonegoro Geopark using the Pentahelix approach. This study employed a qualitative method with data collected through interviews, observations, and documentation, while informants were selected purposively to represent the government, academia, business actors, community groups, and media. The findings indicate that although the five helixes are involved, their roles have not yet been integrated into a systematic collaborative framework. The government contributes through infrastructure provision and regulatory support but lacks a coordinating institution dedicated to geopark management. Academics provide research input, yet it has not formed a comprehensive basis for geosite interpretation. Business actors grow predominantly in recreational destinations, while community groups play essential operational roles but with uneven capacities. The media participates in promoting activities, although it has not succeeded in building a consistent geopark identity. Overall, this study concludes that weak inter-helix integration remains the primary challenge in developing the Bojonegoro Geopark. Therefore, strengthening institutional coordination, improving community capacity, and establishing an integrated communication strategy are essential for achieving sustainable geopark governance.

Industrial development in coastal areas through the construction of a Steam Power Plant (PLTU) has significant economic implications for the sustainability of fishermen's livelihoods. This study aims to analyze the impact of PLTU operations on the socio-economic conditions of fishermen in Teluk Sepang Village, Bengkulu City. This study used a qualitative descriptive approach with a snowball sampling technique, involving 26 small-scale and traditional fishermen directly affected. The results indicate that damage to the coastal ecosystem due to PLTU activities reduces water quality and the availability of fish resources, resulting in decreased catches and income instability. Fishermen are forced to venture farther out to sea, incurring increased operational costs, further putting pressure on household economic conditions. This economic pressure exacerbates fishermen's vulnerability due to limited capital and high dependence on marine resources. Fishermen's adaptation strategy involves diversifying their livelihoods into non-fishing sectors, such as laboring to supplement household income. Changes in social conditions are reflected in the decline in fishermen's solidarity, marked by a weakening of mutual cooperation (gotong royong) and a reduction in collective cooperation due to economic pressures. This study demonstrates that PLTU operations impact the socio-economic structure of fishermen, necessitating sustainable protection and empowerment policies for coastal communities.  

This study aims to analyse the implementation of the Village Operational Funds (VOF) distribution policy as an instrument for realising good governance principles in the Government of Sorong City. The research focuses on the implementation of fund distribution and the application of transparency, accountability, participation, and effectiveness in managing Village Operational Funds. A quantitative approach with a descriptive design was employed. Data were collected through questionnaires administered to 20 respondents and in-depth interviews with five key informants, including village officials and local government representatives. Additional data were obtained through observations of planning and fund utilisation processes, as well as through analysis of regulatory documentation and accountability reports. Data analysis was conducted through data reduction, data presentation, and conclusion drawing. The findings indicate that the implementation of the Village Operational Funds distribution policy in Sorong City has not been carried out in accordance with existing regulations, particularly regarding administrative procedures and fund disbursement mechanisms. This condition is primarily caused by the absence or non-disbursement of operational funds at the village level. Furthermore, the application of good governance principles has not been fully optimised due to limited human resources, weak supervision, and low community participation in planning and evaluation. The study concludes that Village Operational Funds have strategic potential as an instrument for promoting good governance if managed transparently and accountably. Therefore, strengthening institutional capacity, supervision systems, and community participation is essential to support effective village governance in Sorong City.  

Economic empowerment of rural communities through the strengthening of Micro, Small, and Medium Enterprises (MSMEs) is a crucial pillar in achieving national economic independence. One of the fundamental obstacles faced by MSMEs in rural areas is financial exclusion due to low digital literacy and dependence on conventional cash transaction systems. The Community Service Program (KKN) of students from the State Islamic University of North Sumatra (UIN SU) in Pematang Tengah Village was designed to bridge this gap by optimizing the Indonesian Standard Quick Response Code (QRIS). Through an intensive participatory mentoring approach, students acted as agents of digital transformation who educated, trained, and facilitated 10 local MSME actors in adopting non-cash payment technology. The results of the program show a significant shift from digital skepticism to digital trust. The implementation of QRIS has been proven to increase operational efficiency, financial management accuracy, and strengthen the image of business modernity in the eyes of consumers. This article emphasizes that the role of students is not merely as information deliverers, but as catalysts of social capital that is crucial for the sustainability of digitalization at the village level.

Employee work discipline is one of the important aspects of human resource management, especially in service companies that heavily rely on their employees' performance. PT CAI, as an event organizer company, still faces issues related to employee work discipline, such as tardiness, absenteeism without notice, and low consistency in completing work responsibilities. This activity is a form of Community Service by students aimed at increasing employees' understanding and awareness of the importance of work discipline through educational and practical approaches. The implementation methods of the activity include observation, interviews, discussions, documentation, and the implementation of an educational program in the form of work discipline posters as well as providing recommendations for a simple reward and punishment system. The results of the activity show that internal educational media serve as an effective visual reminder in increasing employee awareness of punctuality and work responsibility. This community service activity is expected to support the improvement of employee performance, service quality, and the operational sustainability of PT CAI.

This study aims to estimate coal resources using the kriging method at PT. Inti Bara Perdana, Taba Penanjung, Bengkulu. Geostatistical analysis was applied to evaluate spatial variability of coal quality parameters, including total moisture (TM), inherent moisture (IM), ash content (ASH), volatile matter (VM), fixed carbon (FC), and calorific value (CV). The research utilized drilling data with an average spacing of 80 meters. Variogram modeling was conducted using SGeMS software, employing spherical models to determine nugget, sill, and range parameters. The results show a low nugget effect (0%) indicating strong spatial continuity. The obtained ranges vary between 180–1296 meters depending on the parameter. Blo./ck kriging estimation was performed using block dimensions of 25 × 25 × 8 meters and a coal density of 1.3 ton/m³. The total estimated coal resource up to an elevation of 230 m is 253,500 tons. These findings demonstrate that kriging provides reliable resource estimation and supports mine planning optimization. This research contributes to improving coal resource evaluation accuracy and operational decision-making in open-pit mining.

This study uses an integrated analysis of positive law and Islamic law at Polres Bungo to investigate the reconstruction of sanctions for juvenile offenders during the investigation stage. Empirical trends suggest a procedural and administrative orientation that may restrict substantive rehabilitation, even though Undang-Undang Nomor 11 Tahun 2012 tentang Sistem Peradilan Pidana Anak (Juvenile Criminal Justice System Act) formally adopts restorative justice, diversion, and the best interests of the child as guiding principles. Using a multidisciplinary approach that integrates statutory, theological-normative (shar‘i), and historical considerations, this study uses a normative qualitative design based on library research. The theoretical framework incorporates maqāṣid al-sharīʿah as a normative evaluation instrument, legal effectiveness theory, and punishment theories. The findings reveal a conceptual convergence between Indonesian positive law and Islamic criminal jurisprudence in differentiating criminal responsibility based on maturity and prioritizing rehabilitation over retribution. There are still differences, nevertheless, when it comes to age criteria and the classification of sanctions: Islamic law places more emphasis on moral and biological maturity (baligh and tamyīz), whereas positive law focuses on strict legislative boundaries. The predominance of formal legality over psychosocial assessment at the investigative level runs the risk of undermining rehabilitative goals. In order to maintain proportionality and child protection, this study suggests a reconstructive paradigm that operationalizes maqāṣid-based principles, combines thorough psychological evaluation, and improves diversion measures. In addition to realistically advancing the creation of a more equitable, rehabilitative, and child-centered investigative framework, the research theoretically advances the conversation about harmonizing state and Islamic law.

This study aims to develop a strategic plan for Information Systems and Information Technology (IS/IT) at KR Hotel Palembang by applying the Ward and Peppard methodology. The analysis began with external environment assessment using the PEST framework and internal analysis through the MOST method and Value Chain model. The results were synthesized into a SWOT analysis to identify the organization's strengths, weaknesses, opportunities, and threats. From this, Critical Success Factors (CSF) were formulated to guide the determination of key information system needs. Application portfolio mapping was then conducted using the McFarlan Strategic Grid to classify systems based on their strategic impact. Findings indicate that KR Hotel has strong potential in leveraging digital technologies but faces challenges such as the absence of integrated systems across departments and limited IT training for staff. To address these issues, an integrated system named ZKBiolock was proposed, encompassing modules such as hotel management, financial management, customer relationship management (CRM), human resource training systems, digital promotion, and internal network monitoring and control. This strategic plan is supported by a comprehensive database design, network topology, human resource and infrastructure analysis, investment budgeting, and Return on Investment (ROI) evaluation. The proposed strategy aims to enhance the efficiency and effectiveness of the hotel's operational management.

The police institution is a law enforcement agency whose operational effectiveness heavily depends on the management of human resources to support organizational development and sustainability. The Directorate of Special Criminal Investigation (Ditreskrimsus) holds a strategic role in handling specialized and complex crimes. Its duties involve addressing various forms of criminal activity with high levels of risk and uncertainty. Such risks are often unpredictable and may arise suddenly. Continuous readiness and sustained vigilance in diverse situations can serve as significant sources of work-related stress. One strategy to mitigate work stress is by enhancing Quality of Work Life (QWL). This study aims to examine the relationship between QWL and work stress among members of the Ditreskrimsus of Polda Jambi. A quantitative approach with a correlational research design was employed, involving 115 members selected through purposive sampling. Data were collected online using questionnaires consisting of a QWL scale and a Work Stress scale. Correlation analysis conducted using SPSS indicated that the majority of respondents were in the moderate category. The findings revealed a significant negative relationship between QWL and Work Stress, with a correlation coefficient of r = -0.549 and a significance level of p < 0.001. These results underscore the importance of continuously improving various aspects of QWL as an effective strategy to prevent and reduce work-related stress.

The conversion of agricultural land to non-agricultural land continues to increase along with the pressures of urbanization, industrialization, and settlement expansion. This condition poses risks to food security, environmental sustainability, and farmer welfare. This article reviews literature based on 25 abstracts/research results on LP2B in Indonesia to map policy implementation patterns, the relationship between LP2B and regional spatial planning, inhibiting factors, and the direction of policy strengthening. The method used is a narrative review with thematic synthesis of normative legal studies, juridical-empirical, qualitative, mixed methods, and spatial-quantitative approaches. The results of the review indicate: (1) LP2B is highly dependent on the harmonization of spatial planning policies, especially RTRW/RDTR and licensing mechanisms based on KKPR-OSS; (2) many regions are still stuck at the land inventory-identification stage, not yet reaching the determination and operational protection through LP2B Regional Regulations; (3) dominant obstacles include regulatory asynchronous, weak law enforcement, minimal cross-agency coordination, limited data by name by address, suboptimal socialization, and conflicts of interest in non-agricultural development; (4) incentive-disincentive instruments have not been implemented consistently, although socially farmers tend to accept LP2B protection; and (5) quantitative evidence at the national level shows that LP2B policies have a positive effect on the percentage of rice fields, despite being suppressed by population density and real estate sector growth. This article emphasizes the need for an integrated spatial governance approach, strengthening regional institutions, and designing policies that are socially and environmentally just to ensure that LP2B is effective in maintaining regional food security.

The healthcare sector is increasingly confronted with a VUCA environment (Volatility, Uncertainty, Complexity, and Ambiguity), requiring hospitals to adopt adaptive, resilient, and innovative strategies. This study aims to systematically review the evidence on smart hospital strategies in responding to uncertainty, particularly in improving service quality, operational efficiency, and patient satisfaction. A systematic literature review was conducted using major academic databases, including Scopus-indexed sources, Google Scholar, and Semantic Scholar, covering publications from 2020 to 2026. Articles were selected based on predefined inclusion criteria focusing on hospital management strategies in dynamic and uncertain environments. A total of 10–15 relevant studies were included and analyzed using thematic synthesis. The findings indicate that key strategies in addressing VUCA challenges include digital transformation (e.g., electronic medical records and telemedicine), adaptive and transformational leadership, agile management approaches, and patient-centered care. Digital technologies significantly improve efficiency and decision-making processes, while agile and adaptive leadership enhances organizational responsiveness and resilience. However, several studies highlight that technological advancement alone is insufficient without integrating humanistic values such as empathy, communication, and trust. In conclusion, the most effective hospital strategies in a VUCA world are those that integrate technological innovation with human-centered care. Hospitals must develop flexible, data-driven, and patient-oriented systems to ensure sustainability and competitiveness in uncertain environments. Future research should focus on longitudinal and experimental designs to strengthen causal evidence and explore the integration of digital systems with humanistic healthcare values.

Healthcare organizations are increasingly required to preserve the sustainability of their institutional values by ensuring high-quality services, operational efficiency, and rigorous adherence to risk governance frameworks. RSUD dr. Chasbullah Abdulmadjid Bekasi City continues to face considerable challenges in this regard, particularly due to the limited internalization of core organizational values, disparities in the cultivation of an adaptive culture, and inconsistent employee compliance with established risk management procedures. These issues highlight the necessity for a leadership paradigm grounded in service, empathy, and empowerment.This study investigates the extent to which servant leadership influences the creation and protection of corporate values, while examining the mediating roles of strong adaptive culture and employee compliance doing the implementation of risk management. Employing a quantitative explanatory survey design, the research collected responses from 153 hospital employees, and data were analyzed through Structural Equation Modeling (SEM) to evaluate both direct and mediated causal pathways among variables.The findings reveal that servant leadership significantly strengthens creation and protection of corporate values, not only through direct influence but also by enhancing cultural adaptability and reinforcing compliant behavior in risk-related practices. Leaders who embody service-oriented principles are shown to cultivate work environments that foster mutual trust, organizational learning, and value-based decision-making.This study contributes meaningful empirical evidence to the discourse on leadership, organizational culture, and compliance within public hospital settings. Institutional strategies should prioritize continuous leadership development and comprehensive risk governance training to secure long-term performance excellence and reputational resilience.
