Track: Operations Management

Abstract

This study aims to determine the level of reliability of the gas engine, the root cause of the problem, and propose the implementation of preventive maintenance. Conduct this research on a company that provides electricity to the community. The research method uses Mixed Method with descriptive research type. The analytical tools used are MTBF, MTTR, DMAIC, with supporting methods in Root Cause Analysis and Why-why Analysis. The MTBF and MTTR calculations show that many MTBF and MTTR values do not reach the target. The root causes of downtime problems include dust and dirt—implementation of preventive maintenance including Maintenance Schedule. Thus the company needs to measure Gas Engine Reliability with MTBF, MTTR, root causes of problems with DMAIC, and Preventive Maintenance to reduce downtime in the future.
