Abstract
Production process flows are often the obstacles caused by production machine not functioning. Maintenance policies applied today are corrective maintenance and plan maintenance/time direct. Reliability centered maintenance (RCM) it’s method that can be used optimal maintenance action for every part of machine in galvanizing wire system. Steps above method planning consist of a functional block diagram (FBD), system function and function failure (SFFF), failure mode and effect analysis (FMEA), logic tree analysis (LTA), and task selection (TS). The results of analysis RCM method obtained 392 failure mode divided into 83 failure mode which is classified as critical and obtained 59 critical type part. Furthermore, the most appropriate maintenance action for 83 failure critical mode is 55 failure mode in condition directed (CD), 28 failure mode in failure finding (FF) category. Based on design of RCM, this research can reduce the frequency of machine breakdown on galvanizing wire system by 80.98%.

Summary
Info Naskah: Naskah masuk: 13 Juni 2020 Direvisi: 2 Agustus 2020 Diterima: 13 Agustus 2020. Kebijakan pemeliharaan yang diterapkan saat ini adalah corrective maintenance dan plan maintenance/time direct. Reliability centered maintenance (RCM) suatu metode yang dapat digunakan dalam tindakan perawatan yang optimal bagi setiap part mesin pada system galvanizing wire. Tahapan dalam perencanaan metode di atas terdiri dari functional block diagram (FBD), system function and function failure (SFFF), failure mode and effect analysis (FMEA), logic tree analysis (LTA), dan task selection (TS). Hasil analisis dengan menggunakan metode RCM diperoleh 392 failure mode terbagi 83 failure mode yang tergolong kritis dan diperoleh 59 part jenis kritis. Selanjutnya diperoleh juga tindakan perawatan yang paling tepat untuk 83 failure mode kritis yaitu 55 failure mode masuk kategori condition directed (CD), 28 failure mode masuk kategori failure finding (FF). Berdasarkan perancangan RCM, maka penelitian ini dapat menurunkan frekuensi breakdown mesin pada system galvanizing wire sebesar 80,98%
