PERENCANAAN PERAWATAN DAN PERSEDIAAN SUKU CADANG PADA MESIN POMPA MENGGUNAKAN METODE RCM II DAN RCS

Abstract

Manufacturing companies engaged in the processing of lubricating oil are companies that are active in recycling used oil into new oil (recycled oil) and producing various other types of lubricants. One of the processes that has a high risk in this industry is the hydrofinishing process. The P-101A pump machine is the machine that most frequently experiences failure in this process. Failure Mode and Effect Analysis (FMEA) was used to identify the failure mode and risk priority number of each component. Reliability Centered Maintenance II (RCM II) was used to estimate optimal maintenance intervals, and Reliability Centered Spares (RCS) was used to determine efficient spare parts requirements. The results of the FMEA analysis showed there are 27 components with 28 failure modes. The highest RPN is pressure safety with an RPN of 162. RCM II analysis results in three maintenance tasks: a scheduled restoration task for 3 components, a scheduled discard task for 14 components, and a scheduled on-condition task for 1 component. Based on the RCS method, it is estimated that 51 units of non-repairable spare parts and 10 units of repairable spare parts are required every year.
