Abstract

This study investigates the effectiveness of six milling machines at PT. INKA, a railroad car manufacturing company, focusing on CNC Plano 133 and Horizontal Milling 142. Utilizing Overall Equipment Effectiveness (OEE) and Age Replacement methods, the research aims to optimize machine performance and propose preventive maintenance strategies. Data spanning from January 2021 to December 2022 were collected and analyzed. Results indicate that both CNC Plano 133 and Horizontal Milling 142 exhibit suboptimal OEE values, primarily due to breakdown losses. Applying Age Replacement within 10 days significantly enhances reliability, with post-replacement reliability reaching 100%. The findings underscore the importance of preventive maintenance in improving milling machine reliability and overall productivity, thereby enhancing competitiveness and sustainability in the manufacturing sector. Highlight: Improved productivity: Preventive maintenance boosts milling machines' reliability and effectiveness. Resource efficiency: Analyzing OEE minimizes downtime, optimizes production output. Competitive edge: Enhanced performance sustains competitiveness, strengthens manufacturing sector's sustainability. Keyword: Milling machines, Overall Equipment Effectiveness (OEE), Preventive maintenance, Age Replacement, Manufacturing industry

Abstract

Penumpukan limbah industri herbal menjadi permasalahan karena berdampak pada pencemaran lingkungan, keterbatasan gudang penyimpanan, menyebabkan pembusukan, mengundang hama dan menimbulkan bau tidak sedap. Pendekatan Green Human Resource dengan circular economy dan penerapan teknologi menjadi solusi guna mengatasi permasalahan mitra. Kegiatan abdimas ini kerja sama dengan mitra yaitu Sahabat Mitra Khallaz yang berlokasi di Jalan Al Hidayah, Dusun Pagotan, Keplaksari, Peterongan, Jombang, Jawa Timur. Tim pengabdi memperkenalkan teknologi mesin roasting biji kurma untuk mengolah limbah menjadi produk baru berupa kopi kurma dengan kemasan orisinil yang lebih menarik. Kegiatan pengabdian ini bertujuan membawa pesan kesadaran akan green human resource dengan memadukan teknologi. Tujuan kegiatan untuk meningkatkan pengetahuan tentang makna circular ekonomi dengan pemanfaatan limbah biji kurma menjadi kopi kurma, kesadaran dalam melestarikan lingkungan, menerapkan, serta pengembangan pemasaran dengan digital marketing dan partnership. Metode kegiatan dilakukan dengan 5 tahapan meliputi Sosialisasi Dan Kampanye Internal Green Human Resource; Penerapan Teknologi Upcycle Limbah; Membuat Kemasan Premium; Pelatihan Strategi Marketing; Pelatihan Digital Marketing.  Hasil kegiatan menunjukkan bahwa 95% anggota komunitas memberikan respon positif terhadap peningkatan kesadaran Green Human Resource. Penerapan teknologi upcycle limbah biji kurma berhasil mengalihkan sekitar 80% limbah menjadi produk bernilai ekonomis. Pada aspek pemasaran, 80% peserta menyatakan memahami dan siap memanfaatkan digital marketing, serta 60% menunjukkan kesiapan membangun kemitraan usaha.

Abstract

General Background Inventory management plays a central role in maintaining production continuity and controlling operational costs in manufacturing systems. Specific Background Companies frequently apply Continuous Review and Periodic Review systems to determine optimal order quantities, reorder points, and safety stock levels in order to minimize total inventory cost. Knowledge Gap However, comparative empirical evaluation of both systems within a specific operational context remains limited, particularly in determining which policy generates lower total cost under actual demand conditions. Aims This study aims to analyze and compare the Continuous Review and Periodic Review methods to identify the inventory policy that produces the minimum total cost. Results The findings indicate differences in ordering frequency, safety stock levels, and total inventory cost, with one method demonstrating a lower overall cost based on calculated demand and cost parameters. Novelty The study provides a direct quantitative comparison of two widely applied inventory control systems within a single operational dataset. Implications The results offer practical guidance for managerial decision-making in selecting an appropriate inventory control policy to achieve cost efficiency and operational stability. Keywords: Inventory Management, Continuous Review System, Periodic Review System, Total Inventory Cost, Safety Stock Key Findings Highlights Comparative cost calculations reveal distinct ordering policies between the two control systems. Differences in reorder strategy generate variation in total inventory expenditure. Quantitative evaluation supports selection of a cost-minimizing policy for operational planning.
