Abstract

Dalam praktik operasional PT. XYZ aktivitas perawatan Air Separation Plant (ASP) belum dilaksanakan berdasarkan interval terjadwal sehingga masih didominasi oleh corrective maintenance. Penelitian ini bertujuan untuk menentukan strategi dan penjadwalan perawatan yang optimal dengan menggunakan metode Reliability Centered Maintenance II (RCM II). Penelitian dilakukan dengan mengidentifikasi kegagalan dasar yang menyebabkan kerusakan total pada mesin melalui Fault Tree Analysis (FTA), menganalisis penyebab kegagalan menggunakan Failure Mode and Effect Analysis (FMEA) untuk menentukan komponen prioritas berdasarkan nilai Risk Priority Number (RPN), serta menetapkan kebijakan perawatan dan interval penggantian melalui RCM II decision worksheet. Selain itu, pendekatan Maintenance Value Stream Mapping (MVSM) digunakan untuk memetakan aliran aktivitas perawatan pada kondisi existing dan usulan guna mengidentifikasi aktivitas value added dan non-value added. Analisis FMEA menghasilkan total RPN sebesar 2.149 dengan Expansion Turbine, Storage Tank, dan Turbine Compressor sebagai penyumbang resiko kerusakan utama. Pemetaan melalui MVSM menghasilkan rata rata peningkatan efisiensi sebesar 28,11%. Melalui RCM II decision worksheet diperoleh interval perawatan optimal dan peningkatan Reliability berturut-turut sebesar 1400 jam dan 97,0 % untuk Expansion Turbine, 1444 jam dan 62,93% untuk Storage Tank, 1265 jam dan 53,19% untuk Turbine Compressor.
