Abstract

PT. Vale Indonesia Tbk. is a company engaged in the mining industry, particularly in nickel processing (Ni). The company operates a power plant at Balambano Hydroelectric Power Plant (2x68.5 MW). The company's usual maintenance practice is limited to corrective maintenance, which involves replacing or repairing components only when they are damaged. The aim of this research is to determine the optimal replacement time for preventive maintenance on turbine machines in order to minimize downtime. The age replacement method is used to calculate the replacement interval for components based on their usage life. The research findings show that the mean time to failure (MTTF) of the wicket gate is 2217.824 hours or 92.41 days, which means that the component may experience failure again after operating for that MTTF duration. Therefore, the recommendation is to replace the component every 85 days of operation and perform inspections every 15 days.

Abstract

This study presents an evaluation of supply chain reliability strategies in the garment industry by utilizing the SCOR 14.0 Racetrack Framework. The research was conducted at Raja Konveksi Kaos Makassar, a garment manufacturing company that has encountered recurring issues related to delayed deliveries, inaccurate order documentation, and poor product conditions upon customer receipt. To identify the underlying causes, a Fishbone Diagram was employed for structured root cause analysis. Based on the insights gained, a portfolio of ten improvement projects was formulated, adopting best practices outlined by the Association for Supply Chain Management (ASCM). These projects were classified according to SCOR process categories and then prioritized using a Prioritization Matrix to ensure alignment with organizational goals and resource allocation. Each prioritized project was executed using a Project Charter approach, supported by a Gantt Chart to track implementation timelines and manage activities efficiently. The evaluation phase indicated significant improvements in key SCOR reliability metrics: RL.3.3 improved by 9.23%, RL.3.5 by 2.07%, and RL.3.10 by 3.54%. These results demonstrate that the implemented strategies effectively enhanced supply chain reliability, operational performance, and service quality. Overall, this study affirms the value of the SCOR 14.0 Racetrack Framework as a practical and data-driven tool for evaluating and improving supply chain reliability in the garment industry, offering relevant insights for both academics and practitioners.

Abstract

Lingkungan kerja PT. Mitra Karsa Utama, karyawan dihadapkan pada tingginya beban kerja dan tekanan waktu yang berkaitan dengan maintenance jaringan serta target pencapaian perusahaan. Kelambatan dalam mencapai target dapat berakibat pada teguran dari pimpinan dan pengguna jaringan, menimbulkan kecemasan dan stres berlebih yang menghambat proses kerja. Penelitian ini bertujuan mengevaluasi beban kerja mental karyawan menggunakan metode Rating Scale Mental Effort (RSME) dan National Aeronautics and Space Administration Task Load Index (NASA-TLX). Hasil penelitian menunjukkan bahwa metode RSME lebih efektif dalam mengukur beban kerja, menyoroti variabel seperti Beban Kerja, Kelelahan, Kegelisahan, Performansi, Usaha Mental, dan Kesulitan Kerja. Rekomendasi termasuk peningkatan pemahaman pekerja terhadap tugas, klarifikasi deskripsi pekerjaan, shift kerja terstruktur, dan perekrutan tenaga berpengalaman. Dengan implementasi rekomendasi ini, diharapkan PT. Mitra Karsa Utama dapat meningkatkan kesejahteraan dan kinerja karyawan melalui pemahaman yang lebih baik terhadap faktor-faktor beban kerja mental.
