Abstract

Coal is the largest source of 38% coal-fired power plants globally, the most growth in Asia. In Indonesia, coal-fired power plants dominate, with the total installed power reaching 48.43%. A Belt conveyor is leading equipment for transporting coal to the boiler. The phenomenon of conveyor belt damage such as tearing, peeling, and rupture is an event that occurs in many industries in the world. The purpose of this study was to determine the effects of belt damage, OEE values, and productivity using structural equation modeling (SEM) analysis methods, as well as identify and evaluate the causes of damage to belts, using failure mode and effect analysis (FMEA) methods. The results showed a significant influence between damaged belts with OEE, OEE productivity, and damaged belts on productivity through OEE. FMEA analysis three leading causes of belt damage based on the highest risk priority number (RPN).
