Risk and Reliability Improvement Analysis of Boiler System Using FMECA Method. Case Study : PLTU Nii Tanasa Kendari.

A PLTU must carry out operational tasks continuously to meet electricity needs. Based on historical data PT. PJB Service Kendari for the last three years, there has been an increasing trend of downtime and derating at Nii Tanasa Kendari. The boiler system is one systems that often experiences disturbances. purpose this research a risk analysis improve reliability using FMECA method calculations. required find in detail ways mitigating risks, sorting labeling risks critical components based RPN. results calculations MTTF found 9 13 had value below 50%; values could be achieved preventive maintenance (Rm(t)), maintaining above 60% periodic component replacement (R(t-nT)).
