Abstract

This study aims to analyze the relationship between technology, organization, and human resources variables and the effectiveness of the Planning Information System (SISFOREN) usage at the Army Headquarters (MABESAD), assess the impact of SISFOREN effectiveness on the performance of the planning department, and identify obstacles faced during implementation. A quantitative approach using the Technology Acceptance Model (TAM) was employed, with data collected through structured surveys distributed to planning and budgeting staff members. The findings reveal that technology does not significantly influence effectiveness (), attributed to implementation challenges and users' limited technical understanding. In contrast, organization positively impacts effectiveness (), highlighting the importance of structured communication and organizational support. Human resources also significantly affect effectiveness (), emphasizing the critical need for comprehensive training programs. Furthermore, the effectiveness of SISFOREN significantly enhances planning performance (), demonstrating improvements in data monitoring, decision-making speed, and administrative efficiency. However, obstacles such as inadequate technology integration, user skill gaps, and unsupportive organizational structures persist. The study contributes to understanding information system implementation in military contexts and provides practical recommendations for optimizing SISFOREN's deployment. Addressing these identified issues is essential for maximizing SISFOREN's implementation success and improving its overall efficiency in supporting the Indonesian Army's planning and budgeting operations.

Abstract

In the competitive oil and gas industry, equipment reliability and operational efficiency are critical success factors. The availability of effective spare parts presents a significant challenge that must be addressed to prevent downtime and financial losses. The current problem involves a loss of approximately 100 barrels of oil per day (bopd) due to the failure of one water injection pump (WIP) unit. Therefore, an optimal WIP spare parts planning method is required to maintain operational reliability. This study addresses this issue by determining the reliability condition of WIP units, optimizing maintenance schedules, and selecting appropriate failure data distribution tests using time-to-failure (TTF) analysis. Maintenance optimization for WIP at PT. Z was conducted using Monte Carlo simulation with distribution selection methods, specifically the Bayesian Information Criterion (BIC) and Akaike Information Criterion (AIC). The simulation results revealed that WIP A is in the wear-out phase, whereas WIP B, C, D, and E are in the useful-life phase (WIP D and E with extended operational periods). Based on Monte Carlo simulation results for five WIP types operated over 15 years, optimal maintenance intervals were determined: day 1691 for WIP A, day 1729 for WIP B, day 2160 for WIP C, day 3629 for WIP D, and day 3629 for WIP E from initial operation. Implementing planned maintenance has the potential to significantly reduce costs associated with each WIP unit failure. These research findings can be applied to other equipment to achieve potential cost savings from unplanned maintenance.

Abstract

Construction projects often face the risk of delays, which can affect cost, quality, and schedule performance. This research aims to analyze the factors causing delays in the Engineering, Procurement, and Construction (EPC) Gas Engine Power Plant (PLTMG) project in Sumbawa and to formulate improvement recommendations. The research employs the Partial Least Squares – Structural Equation Modeling (PLS-SEM) method with 67 respondents consisting of the project owner, contractor, and supervision consultant. The research variables include design, financial, resources, contractor, material, external, and owner as independent variables and time overrun as the dependent variable. The results show that the external factor has a positive and significant influence on project delays (? = 0.534; p = 0.000), which includes regulatory changes, extreme weather, permit delays, and socio-cultural influences. The owner factor shows a nearly significant effect (p = 0.092), while design, financial, contractor, material, and resource factors have no significant impact. The research model demonstrates good predictive capability (R² = 0.696; Q² = 0.516). Improvement recommendations focus on mitigating external factors, including establishing a legal team to monitor regulations, developing a flexible work schedule adapted to weather conditions, expediting permits through a dedicated liaison officer, and enhancing communication with the local community. These findings are expected to serve as a reference for stakeholders in managing delay risks in similar construction projects.

Abstract

The availability of safe and sustainable drinking water is a vital necessity for boarding educational institutions. Madrasah Aliyah Negeri Insan Cendekia (MAN IC) Paser faces limitations in the quantity and continuity of clean water supply from external providers, while at the same time possessing a potential surface water source in the form of a lake with a large storage volume. However, the quality of the lake water does not yet meet drinking water standards, as indicated by high turbidity levels and potential microbiological contamination. This study aims to analysis of investment of the design a lake water treatment system into drinking water that complies with the Indonesian Ministry of Health Regulation No. 492 of 2010, as well as to design an efficient and sustainable water management supply chain and ecosystem. The research methods include raw water quality analysis, jar test experiments using several types of coagulants, the design of a water treatment plant (WTP) employing a conventional treatment system, and supply chain analysis based on a systems thinking approach. The results show that a complete water treatment system consisting of presedimentation, coagulation–flocculation, sedimentation, filtration, and disinfection is able to reduce turbidity to meet drinking water quality standards. In addition, the integrated supply chain design supports the operational sustainability of drinking water provision within the MAN IC Paser environment. This study is expected to serve as a model for drinking water self-sufficiency based on local resources in educational institutions.

Abstract

Background: The pulp and paper industry is capital-intensive and operates continuously, making equipment availability a critical determinant of corporate performance. Preventive maintenance is often regarded merely as a cost center, despite its significant potential as a strategic value-creating activity. Objective: This study aims to analyze the influence of preventive maintenance on the financial performance of PT Indah Kiat Pulp and Paper Serang Mill through the serial mediation of Overall Equipment Effectiveness (OEE) and paper machine productivity, offering a novel chain-mediation framework that connects maintenance activities to corporate financial outcomes. Methods: A quantitative approach was employed using Structural Equation Modeling Partial Least Squares (SEM-PLS) with SmartPLS, based on data from 120 internal respondents collected through a five-point Likert-scale questionnaire and triangulated with company operational and financial data. Results: All six hypotheses are statistically supported. Preventive maintenance positively affects OEE (β = 0.570); OEE affects productivity (β = 0.601); and productivity affects financial performance (β = 0.514). Serial mediation is confirmed: OEE mediates preventive maintenance → productivity, while productivity mediates OEE → financial performance. Full serial mediation yields an indirect effect of 0.176. Conclusion: These findings confirm a complete value-creation chain through a novel serial mediation model (preventive maintenance → OEE → productivity → financial performance), extending maintenance management theory by repositioning preventive maintenance as a strategic mechanism for sustainable corporate value creation in capital-intensive manufacturing industries.
