PENJADWALAN PREVENTIVE MAINTENANCE MESIN DRY VACUUM PUMP DI PT XYZ BATAM

Abstract

In the manufacturing industry, ensuring a smooth production process is crucial for maintaining company performance. Machines play a vital role as a production factor that significantly affects the continuity of these processes. At XYZ Batam, frequent machine downtimes disrupt production targets. This study aims to determine the optimal machine maintenance intervals to reduce downtime. The Reliability Centered Maintenance II (RCM II) approach was applied using methods such as Failure Mode and Effect Analysis (FMEA), Mean Time to Failure (MTTF), and Mean Time to Repair (MTTR). The downtime data analyzed covers the period from April 2024 to September 2024. The results indicate that thermal overload repairs on dry vacuum pump no.1 and dry vacuum pump no.2 are the most frequent maintenance activities based on Risk Priority Number (RPN) calculations from the FMEA analysis. Preventive maintenance intervals for machines with the highest downtime rates were determined as follows: dry vacuum pump no.1 requires maintenance every 129,12 hours, and dry vacuum pump no.2 every 151,83 hours.
