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

Pembangunan bendungan merupakan proyek infrastruktur strategis yang memiliki manfaat besar bagi pengendalian banjir, penyediaan air baku, irigasi, serta energi listrik. Namun, proyek konstruksi bendungan memiliki tingkat kompleksitas tinggi dan rentan terhadap berbagai risiko rantai pasok, seperti keterlambatan pengiriman material, fluktuasi harga, kualitas material yang tidak sesuai, serta kendala komunikasi dan logistik. Penelitian ini bertujuan untuk menganalisis dan meningkatkan kinerja rantai pasok pada Proyek Bendungan Cijurey Paket 1 melalui implementasi metode Supply Chain Operations Reference (SCOR) Digital Standard. Pendekatan yang digunakan adalah metode campuran (mixed methods) dengan analisis kuantitatif untuk mengukur kinerja rantai pasok pada indikator RL.2.6, RL.3.15, RL.3.16, Inventory Turnover (ITO), dan Days of Inventory (DOI), serta analisis kualitatif untuk mengidentifikasi akar penyebab permasalahan menggunakan metode 5 Why dan Fishbone Diagram. Hasil evaluasi awal menunjukkan bahwa skor komposit kinerja rantai pasok berada pada tingkat 62,4% atau kategori “cukup”, dengan kelemahan utama pada aspek keandalan pengiriman dan biaya rantai pasok. Melalui rancangan strategi perbaikan berbasis SCOR Racetrack, House of Risk (HOR), serta simulasi Monte Carlo, penelitian ini menyajikan rekomendasi mitigasi risiko yang dapat meningkatkan keandalan, efisiensi, dan efektivitas rantai pasok proyek. Kontribusi penelitian ini tidak hanya memperluas penerapan SCOR DS dalam konteks proyek konstruksi, tetapi juga memberikan panduan praktis bagi manajer proyek dan pemangku kepentingan dalam mengelola risiko rantai pasok pada proyek infrastruktur skala besar.

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

Abstract Dam construction projects face various challenges in supply chain management that can affect the success of the project. This study aims to analyze the implementation of the SCOR Digital Standard (DS) method in improving supply chain performance in the Cijurey Dam Package 1 Project. The research method uses qualitative and quantitative approaches by implementing SCOR Racetrack including the Engage, Define, Analyze, Plan, and Launch stages. The results showed that the baseline performance of RL.2.6 Delivery Performance to Commit Date only reached 73.33% of the target of 90%, Inventory Turnover (ITO) <1.1 times/year of the target ?2 times/year, and Days of Inventory (DOI) reached ±250 days exceeding the maximum target of 180 days. The root of the problem is identified through the 5 Why Analysis and Fishbone Diagram, namely the absence of consignment inventory and regular reconciliation meetings with vendors. The recommended improvement strategies include four improvement projects: Procurement Terms & Conditions Review, Freight Carrier Delivery Performance Evaluation, Regular Reconciliation Meetings, and Consignment Inventory. The implementation of this strategy is projected to increase RL.2.6 to ?90%, reduce the DOI to ?180 days, increase ITO to ?2 times/year, with financial benefits reaching Rp1.29 billion per year.

Abstract

Defect minimization remains a critical operational challenge in continuous polyester fiber manufacturing, where off-merge defects compromise fiber crystallinity and dye uniformity, leading to material downgrading. This study aims to optimize key heat-setting operational parameters—specifically heat-setter temperature and tow speed—to reduce off-merge defect rates in industrial polyester staple fiber production. Utilizing the Taguchi Design of Experiments (L4 orthogonal array) with three replications under commercial production conditions, process parameters were evaluated through Analysis of Variance (ANOVA) and Signal-to-Noise (S/N) ratio analysis under the “smaller-the-better” criterion. Results indicated that heat-setter temperature was the dominant factor influencing defect variability (39.02% contribution, F = 10.66), followed by tow speed (21.95% contribution, F = 6.00), whereas their interaction effect was statistically insignificant (9.76%). Optimal settings were identified at 200 °C temperature and 260 m/min tow speed. Confirmatory trials validated these parameters, reducing the off-merge defect rate from 11.50% to 8.25%, resulting in a net defect reduction of 3.25%. The findings demonstrate that higher thermal energy and optimized tension enhance molecular alignment and the consistency of dye uptake. Industrially, this study provides synthetic fiber manufacturers with an evidence-based, cost-effective optimization approach that significantly reduces scrap rates, improves yield efficiency, and supports sustainable quality engineering in large-scale production environments.
