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

This research aims to analyze the strategic cooperation between PT. Pindad, an Indonesian defense company, and MBDA (Matra Bae Dynamics Alenia), a leading missile systems company from France, in the development and production of the Mistral Atlas platform. This cooperation represents a crucial step in enhancing Indonesia's national defense capacity, particularly in addressing increasingly complex aerial threats. The research examines the collaboration process, technical challenges encountered, and the impact of this partnership on product innovation, competitive advantage, and company performance. The results of Structural Equation Modelling (SEM) analysis indicate that the strategic alliance between PT. Pindad and MBDA has a significant positive impact on enhancing product innovation, as manifested in product value. This alliance not only improves PT. Pindad's employees' skills through technology transfer but also contributes to greater product differentiation, which directly strengthens the company's competitive advantage. Product differentiation, in turn, has a significant impact on PT. Pindad's financial performance, thereby boosting the company's competitiveness in the global defense industry market. This research identifies key factors influencing the success of this strategic cooperation, including alliance quality, goal alignment, and employee skills. Based on these findings, the research provides recommendations for further development in the defense industry, particularly in enhancing product innovation and strengthening competitiveness through effective strategic collaboration. Thus, this research is expected to contribute significantly to understanding strategic cooperation in the defense industry and to support efforts to increase Indonesia's defense self-reliance.

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

Small and Medium Enterprises (SMEs) in the metal industry in Mekarmaju Village, Bandung Regency, have great potential to support the local economy and the manufacturing industry supply chain. However, in practice, metal SMEs still face various structural problems. This study aims to examine financial performance due to the development of a business and operational model for a material center for SMEs in the metal industry. This study uses a qualitative descriptive approach. The data collection techniques used in this study are literature review, field observation, and focus group discussion. The data obtained was analyzed using qualitative descriptive analysis through the stages of data reduction, data presentation, and conclusion drawing. The results of the study show that the establishment of a material center with an integrated business model is an effective strategy to strengthen and develop metal SMEs. Through improvements in the supply chain, raw material management, logistics, warehousing, and the implementation of coordinated quality control, this model increases the efficiency, consistency of quality, and competitiveness of SME products. Its success is highly dependent on operational readiness, commitment to cooperation among stakeholders, and continuous assistance from the government, especially the role of the Ministry of Industry.
