Usulan Penjadwalan Perawatan Mesin Roasting dengan Menggunakan Metode Failure Mode Effect Criticality Analysis (FMECA) dan Reliability Centered Maintenance (RCM)

Abstract

Broad Coffee and Roastery is a cafe that produces coffee beans. This research was carried out on a machine that produces roasted coffee beans. The maintenance policy implemented at this time is corrective maintenance where repairs are only carried out when the machine is damaged, this results in sudden machine damage and causes machine reliability to decrease accompanied by large machine downtime, causing losses in terms of time and costs, because hampered the production process. The aim of this research is to provide suggestions for scheduling machine maintenance by implementing preventive maintenance on roasting machines using the Reliability Centered Maintenance and Failure Mode Effect and Criticality Analysis methods with the expected output being to prevent machine damage so that machine reliability is maintained and lower repair costs. optimal based on the maintenance interval obtained. The critical component of the roasting machine is the barrel with preventive maintenance is scheduled discard task for damaged/perforated barrel components with a maintenance interval of once every 13,21 days and scheduled restoration task, namely the barrel component does not rotate with a maintenance interval of once every 13,72 days. Implementing preventive maintenance using the RCM method results in optimal maintenance costs of Rp 58.780.864 by comparing the cost of losses caused by damage to the machine of Rp 83.750.000, resulting in a difference of Rp 21.219.136
