Description
Summary:The main objective of this paper is to determine the performance of the KRL Komuter maintenance system at the Depok depot. The approach used is DMAIC to identify the main causes of failure to repair the maintenance process with a Failure Mode and Effects Analysis (FMEA). The research has identified the main factors that have caused the disruption of the electric trains handled by Depo Depok namely 1) The high level of disturbances that occur without prior warning, 2) The unavailability of spare parts, 3) The decrease of operational capability of component, 4) The deviation of the repair and maintenance activities compared to the SOP, and 5) The lack of knowledge and work experience of the technicians, inparticular the new ones. In general, it has been found that the main cause of the disruption of the commuter trains are the failure of the propulsion system, both concerning the electrical and mechanical parts. Therefore, this research has suggested that improvement should be done mainly in the propulsion maintenance including a better compliance to the maintenance procedure/manual, a better spare parts availability in the depo, and a more adequate technicians in terms of numbers and skill.
