PEMODELAN PENINGKATAN KEHANDALAN DENGAN METODE ROOT CAUSE ANALYSIS DAN FMEA PADA PERUSAHAAN PEMBANGKIT LISTRIK

Abstract

XYZ is a company engaged in the generation of electrical energy. Reliability for power generation companies is very vital for the company's performance appraisal is based on the readiness of the unit to generate electricity load demand PLN (State Electricity Company). To support the reliability of the company has designed a system that is based on the reliability maintenance (RCM). RCM application at PT XYZ is dominated by mostly preventive maintenance based on time and baseline. Meanwhile failures still occur marked by numerous corrective maintenance that still occur on critical equipment, causing derating production unit. Besides the efficiency of preventive maintenance is also doubtful, the amount of PM task that has become a waste of maintenance costs. The pattern of effective maintenance necessary to minimize disturbance. As a baseline, the analysis Root Cause Analysis is required to determine the priority maintenance. After that increase reliability by using Failure Mode and Effect Analysis (FMEA) was conducted with a focus on the criteria of occurence, severity, and detection to determine the Risk Priority Number (RPN). To enhance decision-making systems have used system analysis history data interference as well as MTBF and MTTR. Result of the merger of these methods are known to determine the behavior maintenance task-a task that really affect the reliability of the unit.
