Abstract

The Robot Welding machine is one of the primary production equipment at PT. XYZ with a high utilization rate, requiring an effective maintenance system to ensure its operational reliability. The existing maintenance system is predominantly based on corrective maintenance, resulting in recurring failures, increased downtime, and higher maintenance costs. This study aims to identify critical components, determine appropriate maintenance strategies using the Reliability Centered Maintenance (RCM) method, and analyze maintenance cost efficiency. The research employs the Reliability Centered Maintenance (RCM) approach supported by Failure Mode and Effects Analysis (FMEA), Risk Priority Number (RPN), and Logic Tree Analysis (LTA). The analysis identified four critical components: Contact Tip, O-ring, Feeder Roller, and Conduit Cable (Liner). Based on the RCM Decision Worksheet, the Contact Tip is recommended for Time-Based Maintenance (TBM), while the O-ring, Feeder Roller, and Conduit Cable (Liner) are recommended for Condition-Based Maintenance (CBM). The maintenance cost analysis indicates that the total corrective maintenance cost was IDR 5,177,177, whereas the proposed preventive maintenance cost was reduced to IDR 4,650,000, resulting in a cost saving of IDR 527,177 or approximately 10.18%. The findings demonstrate that the implementation of the Reliability Centered Maintenance method can improve the effectiveness of the maintenance system while reducing maintenance costs for the Robot Welding machine at PT. XYZ.

Abstract

This study aims to evaluate the effectiveness of the Punch Hole machine at PT. XYZ using the Overall Equipment Effectiveness (OEE) method, identify the factors causing performance losses through the Six Big Losses analysis, and propose improvement strategies. A descriptive quantitative approach was employed using operational data from January to December 2025, including operating time, downtime, production output, and defective products. Data were collected through observation, interviews, and documentation, then analyzed using the OEE indicators (Availability, Performance, and Quality), followed by Six Big Losses and Fishbone Diagram analyses. The results indicate that the OEE value of the Punch Hole machine ranged from 41% to 63%, which is below the world-class standard of 85%. The dominant factors reducing machine effectiveness were Reduced Speed Losses (35%) and Equipment Failure Losses (12%). The Fishbone Diagram revealed that the primary causes originated from machine, method, and material factors. The novelty of this study lies in integrating OEE, Six Big Losses, and Fishbone Diagram analyses to develop a preventive maintenance strategy for improving machine effectiveness and production productivity.
