Reduce Machine Downtime using Reliability and Root Cause Analysis for Sustainable Industry

Abstract

This research aims to find the level of reliability of the main engine of boats, to find the root causes of downtime problems of the main engines of boats, and to obtain corrective and preventive mitigation proposals. The research uses the Weibull distribution, Root Cause Analysis (RCA) supported by Fault Tree Analysis (FTA), Pareto diagram, and Five-Whys Analysis, as well as corrective action and preventive action. The results show a level of engine reliability is fifty-three percent, and the dominant root cause of the problems is the oil and tank type. The corrective suggestion is to use more experienced technicians and Pertamina quality of oil and filters. In addition, making additional Standard Operating Procedures (SOP) for preventive mitigation using standard Pertamina oil, routine tank cleaning, and various activities to strengthen employee relations.
