Usulan Perbaikan Sistem Perawatan Mesin dengan Preventive Maintenance Menggunakan Metode Failure Mode Effect Criticality Analysis (FMECA) dan Reliability Centered Maintenance (RCM)

Abstract

PT. Mutiara Mukti Farma is a pharmaceutical industry engaged in the production of medicines. This research was conducted on factory machines that produce tablet-type drugs. The current maintenance policy is corrective maintenance where repairs will only be carried out if a machine is damaged, this results in sudden machine damage and causes machine reliability to decrease accompanied by large machine downtime resulting in losses in terms of time and costs due to delays in the production process. The purpose of this study is to propose improvements to the maintenance system through the application of preventive maintenance on coating film machines using the Reliability Centered Maintenance and Failure Mode Effect and Criticality Analysis methods with the expected output being able to prevent engine damage so that the reliability of the machine is maintained and obtain repair costs. optimal based on the treatment interval obtained. The critical components obtained in the coating film machine as the machine with the greatest frequency of damage are the electric motor components and the spray nozzle with a preventive maintenance policy of 4, namely 1 scheduled discard task, namely the electric motor components that die with maintenance intervals of 107.06 days once and 3 Scheduled restoration task, that is, the electric motor component emits foreign sounds with a maintenance interval of 48.33 days and the spray nozzle component with a maintenance interval of 22.37 days. The application of preventive maintenance with the RCM method produces optimal maintenance costs to be incurred, namely Rp. 51,361,532,925. By comparing it with the cost of losses caused by damage to the machine, a difference of Rp. 105,385,908,509 is obtained.
