Abstract

The development of the manufacturing industry requires companies to maintain product quality while ensuring sustainable operational efficiency. One critical factor in production continuity is the implementation of an appropriate machine maintenance strategy. This study was conducted at PT SGE on the Center Bearing Case (CBC) production line, which frequently experienced sudden breakdowns, leading to downtime and production delays. The objective of this research is to analyze machine failure patterns using the Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) methods to design an optimal preventive maintenance schedule. Machine failure data were collected from July to December 2024. The analysis revealed variations in MTBF values, ranging from 181 hours on the Fuji Auto Lathe to 2,358 hours on the Kiwa Drilling machine. MTTR values ranged from 1.6 hours on the Radial Drill to 5 hours on the NC Takisawa Lathe. Machine availability was recorded between 98.31% and 99.87%. Based on these results, a preventive maintenance schedule was proposed with intervals ranging from 8 to 98 days, tailored to each machine’s characteristics. The proposed schedule is expected to reduce downtime, extend machine life, and enhance the company’s operational efficiency. Keywords: Downtime, MTBF, MTTR, Preventive Maintenance
