Perencanan Perawatan Pada Mesin Screw Press dengan menggunakan RCM (Reliability centered Maintenance) Pada PT.PP.London Sumatera Turangie Palm Oill Mill

Abstract

A maintenance plan of machine is required in every month for every company. However, PT. PP. London Sumatra Indonesia Turangie Palm Oil Mill still runs the non-scheduled maintenance and not in a comprehensive way. The study aims to conduct a schedule for screw press machine maintenance in order to improve the product quality and decrease the production failure risk. Also, the research aims to giva an aid to decrease the workload while carrying out the routine maintenance. The RCM method includes several phases, namely: Fault Tree Analysis (FTA), Failure Mode and Effect Analysis (FEMA), the component replacement interval, the determination of failure consequences, Condition Direct (CD), and Time Direct. Through these phases, the level of failure risk can be decreased. According to the damage frequency as much as 44.86% and the lost work time caused by the machine breakdown as much as 56.12%. RCM also can be utilized to increase the product quality, and prevent or detect the failure or hidden failure at once. Thus, the double failure with a serious consequence can be decreased
