Abstract
PT Industri Kereta Api (Persero) is a national railway vehicle manufacturer that is highly dependent on the Reliability of its production machinery, particularly The Gas Metal Arc Welding (GMAW) XD350S machine at PT Industri Kereta Api (Persero) recorded 30 failure incidents with 4,550 minutes of total downtime in 2025, contributing 77% of overall welding machine downtime. The existing three-month preventive maintenance policy has proven insufficient in reducing unplanned breakdowns. This study aims to identify critical components and determine optimal maintenance intervals using the Reliability Centered Maintenance II (RCM II) method, through FMEA analysis, Weibull distribution testing, and MTTF and MTTR calculations. Four critical components were identified: Wire Feeder, Welding Control PCB, Feed Roller, and Inner Liner, with optimal maintenance intervals of 2,115.05, 3,900.67, 1,598.39, and 1,975.42 hours, respectively. Implementation of this RCM II-based schedule is expected to minimize unplanned downtime and improve machine reliability at PT INKA (Persero).
