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 study is developed as a conceptual paper that analyzes halal marketing practices through a maqashid shariah lens across three operational domains: digital marketing, customer service and business administration. The paper is motivated by recent developments in the global halal economy, the stronger linkage between halal assurance, governance quality and digital transparency, and Indonesia's policy acceleration toward mandatory halal implementation in October 2026. Methodologically, the study uses a structured literature review and conceptual synthesis of international reputable journals and relevant Indonesian journals, complemented by policy and industry reports. The analysis maps prior findings into maqashid dimensions (protection of religion, life, intellect, wealth and dignity) and translates them into practical indicators of honesty, transparency, fairness, consumer protection and procedural reliability. The paper argues that credible halal marketing depends not only on promotional messages but also on service conduct and disciplined administrative governance. It contributes a conceptual framework and practical propositions for evaluating halal marketing practices in MSMEs and service businesses.

This study was conducted at Alok Market, Sikka Regency. The objectives of this study werw to identify the sources and utilization of traders’ business capital and to determine the influence of business capital on the income of market traders. The type of research employed was quantitative research. The population of this study consisted of traders at Alok Market, Sikka Regency. The research sample was selected using purposive sampling, with a total of 30 respondents. Data collection techniques used in this study included structured interviews (numerically based) and direct observation. The data analysis techniques applied were descriptive quantitative analysis and simple linear regression analysis. The results of the study indicated that 50-70% of business capital was obtained from traders’ own capital, while 30-45% originated from loan capital. In terms of capital utilization, 89% of the capital was used for asset investment and 80% for operational cost requirements. The findings of this study also confirmed that business capital had a significant influence on the income of traditional market traders.

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.

Micro, Small, and Medium Enterprises (MSMEs) are highly vulnerable to a wide range of business risks that may threaten their operational continuity and long-term sustainability. These risks include financial instability, market fluctuations, supply chain disruptions, regulatory changes, and limited managerial capacity. This study aims to describe the implementation of risk management practices in MSMEs by examining the processes of risk identification, analysis, evaluation, and control in accordance with the specific characteristics and limitations of MSME operations. The research applies a qualitative method using a document study approach to explore and analyze the phenomenon of risk management within MSMEs. The data utilized consist of secondary sources, including scholarly journal articles, previous empirical research findings, official publications from relevant institutions, government reports, and other publicly accessible documents related to MSME development. The findings reveal that although MSME actors generally recognize the existence of various business risks, the practical implementation of structured and systematic risk management remains suboptimal. Many MSMEs still apply informal, reactive, and experience-based strategies rather than comprehensive risk management frameworks, indicating the need for improved awareness, training, and institutional support.

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.

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.

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 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.

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.  

Employee work discipline is one of the important aspects of human resource management, especially in service companies that heavily rely on their employees' performance.

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.

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.

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.

The retail industry is currently facing increasingly intense competition, requiring optimal supply chain efficiency. Warehouses play a strategic role in controlling inventory flows and supporting a company’s operational performance.

This research employs a quantitative method by distributing questionnaires to 40 respondents from the warehouse, purchasing, and procurement divisions using a saturated sampling technique. The research instrument uses a Likert scale. Data analysis was conducted using validity and reliability tests, classical assumption tests, multiple linear regression analysis, t-test, F-test, and coefficient of determination with the assistance of SPSS software. The results show that supplier compliance with SLA and delivery timeliness have a positive and significant effect, both partially and simultaneously, on warehouse operational performance. Therefore, improving supplier compliance with SLA and delivery timeliness can enhance optimal warehouse operational performance.

The Indonesian hospitality industry is currently facing a post-pandemic "profitability paradox," a phenomenon where increased occupancy rates do not guarantee a proportional increase in net profit margins due to persistent operational cost inflation. This study aims to evaluate operational cost efficiency strategies and their impact on profitability across three star-rated hotels with contrasting locational and market characteristics: @Hom Hotel Kudus (Central Java), Grand Verona Samarinda (East Kalimantan), and FUGO Hotel Banjarmasin (South Kalimantan). This research adopts a descriptive qualitative approach with a comparative multiple-case study design. Data were collected through in-depth interviews with top management, participant observation, and financial document analysis. The results reveal that geographical characteristics and market segments are the primary determinants in selecting efficiency strategies. (1) Hom Hotel Kudus, located in a secondary industrial area, implements Lean Operations strategies through workforce multi-skilling to address market price sensitivity. (2) Grand Verona Samarinda, in the East Kalimantan business hub, focuses on Supply Chain Engineering by localizing raw materials to mitigate high logistical costs. (3) FUGO Hotel Banjarmasin, in the lifestyle segment, adopts Technology-Driven Efficiency to suppress utility costs without degrading the guest experience. The study concludes that sustainable profitability is achieved not through aggressive cost-cutting, but through strategic cost management adaptive to local contexts. These findings provide a new managerial framework for the hospitality industry to shift from a revenue-centric orientation to value optimization.

Drug stockouts in hospitals pose significant risks to service quality, patient safety, and operational efficiency. This study aimed to analyze how drug demand planning and procurement processes at Johar Baru Regional General Hospital contribute to stockout occurrences and to develop data-driven recommendations based on supply chain management principles. A qualitative descriptive design was employed using data triangulation. Data were collected through in-depth interviews with the Head of the Pharmacy Installation, procurement staff, and warehouse pharmacists, complemented by direct observation and analysis of 2024 planning and procurement documents. Thematic analysis was conducted with the support of NVivo software to identify patterns and relationships among key variables, including drug demand planning, procurement, and inventory management.Findings reveal that stockouts stem from interconnected weaknesses in planning accuracy, procurement coordination, and inventory control systems. Effective stock management depends not only on increasing supply but also on improving data quality, integrating inventory information systems with operational workflows, and enhancing cross-functional collaboration. Recommended strategies include implementing a minimum stock alert system integrated with the Hospital Management Information System (HMIS), strengthening standard operating procedures for stockout response and procurement confirmation, improving integration between HMIS, the National Formulary, and budgeting systems, and applying consumption based planning methods combined with ABC VEN analysis to optimize inventory control.

This study examines the influence of memorable tourism experiences and operational risk management in tourist train transportation on positive Word of Mouth (WOM), with tourist satisfaction serving as a mediating variable. A quantitative approach was employed, and data were processed using SEM-PLS 4. The research sample consisted of 247 respondents who had used tourist train services within the past year. The results reveal that both effective risk management practices and memorable tourism experiences perceived by tourists significantly impact tourist satisfaction. Additionally, tourist satisfaction plays a crucial mediating role in generating positive WOM. The study highlights that memorable tourism experiences, including aspects such as comfort, scenic views, and the quality of service, significantly enhance tourist satisfaction. Furthermore, operational risk management, which includes ensuring passenger safety, maintaining service reliability, and handling emergencies effectively, is essential for cultivating satisfaction and positive WOM. The findings suggest that businesses in the tourism industry, particularly those operating tourist trains, should prioritize both risk management and creating memorable experiences to foster customer loyalty and enhance WOM. This study contributes to understanding the dynamic relationship between risk management, customer satisfaction, and WOM in the tourism sector, providing valuable insights for improving service strategies in tourist train transportation.

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 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.
