Abstract

PT. Wartsila Indonesia, as the manager of the Lombok Gas and Steam Engine Power Plant (PLTMGU) has an obligation to maintain an Equivalent Availability Factor (EAF) above 90%. In 2024, EAF will be recorded at 96.97%, with a total outage of 3,726 hours due to Planned Outage (PO) and Force Outage (FO). For 2025, EAF is predicted to be 90.02% with a PO of 7,958 Hours. The planned duration of the PO for 32,000 hours of maintenance is 18 days or 432 hours. The total number of machines that will carry out maintenance of these 32,000 hours is nine Wartsila machines W20V34DF. This study aims to plan a 32,000-hour maintenance activity schedule using the Work Breakdown Structure (WBS) method, and the Critical Path Method (CPM). The study successfully shortened the planned maintenance duration from 18 days (432 hours) to 15 days (345 hours), saving 87 hours per machine. This reduction in maintenance duration can increase EAF and anticipate FO by providing a UOH allocation of 274 hours. With this allocation, the EAF Prediction in 2025 increased to 90.66% beyond the initial prediction. These results confirm the importance of careful planning and management of maintenance schedules to maintain operational sustainability and improve power plant performance.

Abstract

Gas turbines are internal combustion engines used as a primary energy source in Gas Power Plants (PLTG). To ensure the reliability and quality of gas turbine repair outcomes, effective project management supported by employee capability and technological infrastructure is essential. This study aims to analyze the influence of employee capability and technological support on project management performance and its subsequent impact on product quality at PT Nusantara Turbin dan Propulsi. A quantitative approach was employed using a descriptive and verification research design, involving 80 research samples. The sample consisted of employees from the operations, marketing, and finance divisions involved in the FT8 gas turbine repair project. Data were collected through Likert-scale questionnaires and analyzed using classical assumption tests, path analysis, t-tests, and F-tests. The results indicate that employee capability and technological support have a positive and significant effect on project management performance (Adjusted R² = 61.6%). Furthermore, the three variables—employee capability, technological support, and project management performance—also significantly influence product quality (Adjusted R² = 80%). Project management performance is proven to be a partial mediator in the relationship between internal capabilities and product quality. These findings emphasize the importance of integrated management of human resources and technological support in project execution to achieve high-quality products

Abstract

This study aims to evaluate the implementation of Project Quality Management (PQM) in the First Year Inspection (FYI) milestone of the Muara Tawar Add-On Combined Cycle Power Plant (PLTGU) Block 2 project, and to design an integrated business process using the lean construction approach. A mixed-methods research design was applied, combining observation, in-depth interviews, and document analysis. The findings reveal that the PQM implementation, based on PMBOK 7 principles—namely Quality Planning, Quality Assurance, and Quality Control—was mostly at a “partial fit” level due to non-standardized documentation and delays in corrective actions. The FYI business process was mapped using Value Stream Mapping (VSM) and Big Picture Mapping (BPM) to classify value-added (VA), non-value-added (NVA), and necessary non-value-added (NNVA) activities. Of the 23 total activities analyzed, 14 were identified as value-added, while 2 were classified as wasteful. The main causes of inefficiency included waiting time, unnecessary inventory, and excessive transportation. These were mitigated through the integration of collaborative spreadsheets and improved stakeholder coordination. The study emphasizes the importance of having a single source of truth in defect monitoring among project stakeholders (owner, contractor, consultant) to enable better communication and decision-making. Results demonstrate that the resolution of FYI pending items was completed earlier than the planned schedule, validating the effectiveness of integrating lean construction tools to enhance PQM outcomes in power plant construction projects.

Abstract

This study evaluates the feasibility of implementing Public-Private Partnership (PPP) schemes in the energy conservation sector, specifically for street lighting infrastructure in West Lombok Regency. The research employs Value for Money (VfM) analysis and comprehensive project risk assessment to determine investment viability. Using quantitative methodology, the study analyzes technical specifications, financial projections, and risk allocation strategies for 12,915 street lighting points across 10 sub-districts. Financial feasibility indicators show positive Net Present Value (NPV) of Rp 12.66 billion, Internal Rate of Return (IRR) of 15.81%, and payback period of 4.76 years. The Weighted Average Cost of Capital (WACC) is calculated at 9.34%. Risk analysis identifies 24 critical risks categorized across planning, construction, and operational phases, with appropriate mitigation strategies. The study concludes that PPP implementation for street lighting in West Lombok Regency is technically and financially feasible, offering energy efficiency improvements of up to 60% compared to conventional systems while ensuring sustainable public service delivery through availability payment mechanisms.
