| dc.description.abstract | This research discusses the maintenance system of crude palm oil production
machines at the PT Sawita Inter Perkasa palm oil mill. In producing crude oil, the
company uses a corrective maintenance system that repairs the machine if damage
occurs first. However, this method is not optimal because it takes a long time to
repair, losses in high maintenance costs and production will decrease. Therefore,
another method is needed to optimize the maintenance system. In this research, a
preventive maintenance system is carried out. The method used in this research is
the Failure Mode Effect Criticality Analysis method to determine critical
components on the machine and the Reliability Centered Maintenance method to
determine preventive task policies on machine components. Obtained critical
components on the screw press machine as a machine with the greatest frequency
of damage are worm screw and presscage components with a preventive
maintenance policy of 5, 1 scheduled discard task, namely on broken worm screw
components with a maintenance time interval of 26, 74 days, 4 scheduled
restoration tasks, namely on sompel and curved worm screw components with a
maintenance time interval of 26, 73 days, broken and worn presscage components
with a maintenance time interval of 21.51 days and perforated presscage
components with a maintenance time interval of 21.51 days once. The results of the
application of preventive maintenance with the RCM method are obtained
