Optimalisasi Sistem Pemeliharaan pada Mesin Bagging Phonska 5 melalui Pendekatan Reliability Centered Maintenance di PT XYZ

Abstract

Mesin bagging Phonska 5 berperan penting dalam proses pengantongan pupuk, namun tingginya gangguan operasional menunjukkan adanya permasalahan keandalan, khususnya pada dump door. Penelitian ini bertujuan mengoptimalkan sistem pemeliharaan menggunakan pendekatan Reliability Centered Maintenance (RCM) dengan analisis keandalan melalui parameter Mean Time Between Failure (MTBF) dan Mean Time To Repair (MTTR). Hasil menunjukkan bahwa dump door memiliki kontribusi gangguan terbesar, dengan sliding gate, solenoid valve, dan pneumatic piston sebagai komponen dengan risiko kegagalan tertinggi. Nilai MTBF tertinggi terdapat pada sliding gate sebesar 6.243,71 jam dan terendah pada load cell sebesar 328,62 jam, sedangkan MTTR tertinggi terjadi pada solenoid valve sebesar 20,93 jam. Strategi Condition Directed Maintenance (CD) direkomendasikan melalui pengembangan RCM Decision Worksheet, checksheet preventive maintenance, dan One Point Lesson (OPL) untuk meningkatkan efektivitas pemeliharaan, mengurangi downtime, dan meningkatkan keandalan mesin.

The Phonska 5 bagging machine plays an important role in fertilizer packaging, but frequent disruptions indicate reliability issues, particularly in the dump door unit. This study aims to optimize the maintenance system using a Reliability Centered Maintenance (RCM) approach with reliability analysis based on Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR). The results show that the dump door contributes the highest failure rate, with the sliding gate, solenoid valve, and pneumatic piston as the highest-risk components. The highest MTBF is observed in the sliding gate (6,243.71 hours), while the lowest is in the load cell (328.62 hours), and the longest MTTR occurs in the solenoid valve (20.93 hours). A Condition Directed Maintenance (CD) strategy is recommended through the development of an RCM Decision Worksheet, preventive maintenance checksheets, and One Point Lessons (OPL) to improve maintenance effectiveness, reduce downtime, and enhance reliability.
