Track: Maintenance and Reliability

Abstract

PT XYZ is a leading distributor of heavy equipment in Indonesia. During Covid-19 pandemic situation some heavy equipment has stopped operating, but inspection are still required. With excellent inspection and follow-up performance the potential for failure can be reduced so that the Physical Availability (PA), Mean Time Between Failure (MTBF) and scheduled breakdown hours performance of the unit are better. PT XYZ has three basic principles of maintenance strategy namely preventive management, predictive management and corrective maintenance. Based on the results, the percentage of inspection follow up with the percentage of PA shows a moderate positive correlation, and the correlation within the percentage of inspection follow up and the performance of MTBF is a weak correlation. Scheduled breakdown hours and the percentage of PA level shows no correlation between those two variables. The correlation between scheduled breakdown hours and MTBF performance is a weak negative correlation. The top three of Risk Priority Number (RPN) values are owned by the electrical system (500), brake system (400), and engine components (256). The Risk Severity Number (RSV) values for the top priority components are 50, 50, and 64 respectively.
