Risk Analysis Of Bogie Maintenance TB 1014 Using FMEA Method

ABSTRACTThe bogie is a vital component in the railway system that functions to support the load, maintain stability, and ensure the smooth running of the train. Damage to the bogie can cause safety problems and reduce passenger comfort. This study aims to analyze the risk of failure of the TB 1014 bogie component on the K3 01430 train using the Failure Mode and Effect Analysis (FMEA) method as a case study at the Surabaya Pasar Turi (SBI) Train Depo. Data were collected through field observations, technician interviews, and bogie component inspections. The analysis was carried out by assessing the Severity, Occurrence, and Detection parameters to obtain the Risk Priority Number (RPN) value for each component. The results showed that the shock absorber, block brake sprinkler, and wheels had the highest RPN values of 140, 120, and 108, respectively, which were maintenance priorities. All components had RPNs below 200 so the recommended maintenance strategy was corrective maintenance. The FMEA method has proven effective in helping to identify, assess, and prioritize failure risks, so that it can be used as a basis for developing more targeted maintenance strategies and increasing train operational reliability.
