ABSTRAK PT. SMART Tbk, Surabaya adalah pabrik pengolahan minyak dan margarin dengan bahan baku Crude Palm Oil (CPO) dari buah kelapa sawit. Dalam melakukan pengolahan margarin didukung oleh mesin pendingin amonia. Tujuan penelitian ini adalah untuk perencanaan kegiatan perawatan sehingga meningkatkan efektifitas kerja alat serta mengurangi angka kecelakaan yang disebabkan oleh kerusakan alat. Metode yang akan digunakan dalam penelitian ini adalah Metode Reliability Centered Maintenance II (RCM II). Failure Mode and Effect Analysis (FMEA) dan Risk Priority Number (RPN) digunakan untuk mengidentifikasi dan menilai resiko kegagalan fungsi yang ditimbulkan oleh peralatan mesin pendingin amonia. Analisa kuantitatif akan dimasukkan dalam penentuan interval waktu perawatan optimal dengan memperhatikan biaya perawatan (CM) serta biaya kerusakan (CR). Dari hasil penelitian diketahui bahwa pada 15 equipment terdapat 18 bentuk failure mode yang dapat mengakibatkan kegagalan pada mesin pendingin ammonia, dan terdapat RPN tertinggi sebesar 27 pada komponen belt fan kondensor dan fan kondensor. Hasil penilaian resiko menunjukkan bahwa terdapat 4 failure mode yang dapat dicegah dengan menggunakan scheduled restoration task. Terdapat 6 failure mode yang dapat dicegah dengan menggunakan scheduled on conditional task. Interval waktu maintenance yang dilakukan pada mesin pendingin amonia adalah solenoid valve 2160 jam, belt fan kondensor 127,4 jam, fan kondensor 2160 jam, starter panel 252,7 jam, motor kompresor 17 jam, pompa kondensor 135,3 jam, filter/strainer 2160 jam, pressure gauge 4320 jam, stop valve 2160 jam, check valve 2160 jam Kata Kunci: FMEA, Interval Waktu Perawatan, Mesin Pendingin Ammonia, RCM II ABSTRACT PT. SMART Tbk, Surabaya is an oil and margarine processing factory with raw materials of Crude Palm Oil (CPO) from palm fruit. In the margarine processing, it is supported by ammonia refrigeration machine. This study purpose is to plan the maintenance activities so it can improve the tool effectiveness and reduce the number of accident cause by equipment damage. The method to be use in this research is Reliability Centered Maintenance II (RCM II) method. Failure Mode and Effect Analysis (FMEA) and Risk Priority Number (RPN) are used to identify and assess the malfunction risk used by ammonia refrigeration equipment. Quantitative analysis will be included in the determination of optimal maintenance time interval with observing to Cost Maintenance (CM) and Cost Repair (CR). Respectively, the result from the research, it is known on 15 equipments that there are 18 failure modes which can cause failure in ammonia refrigeration, and there is the highest RPN with value of 27 on belt fan condenser and fan condenser. Risk assessment results show that 4 failure modes can be prevented by using schedule restoration task. And there are 6 failure modes can be prevented by using schedule on conditional task. Maintenance time interval that performed on ammonia refrigeration is solenoid valve 2160 hours, belt fan condenser 127,4 hours, fan condenser 2160 hours, starter panel 252,7 hours, motor compressor 17 hours, pump condenser 135,3 hours, filter/strainer 2160 hours, pressure gauge 4320 hours, stop valve 2160 hours, check valve 2160 hours. Keywords: FMEA, Maintenance Time Interval, Ammonia Refrigeration Machine, RCM II
