Abstract—The objective of this research is to reduce the breakdown for the gas turbine in a combined cycle power plant through the collected gas turbine breakdown. The use of Pareto diagram is apply to select the issues. The electricity production in the current condition is then studied by focusing on the operation, equipment, and other machinery that affect breakdowns. The breakdown causes are then analyzed using be cause and effect diagram. The failure mode and effect analysis (FMEA) is then performed to determine the cause of the breakdown. The criteria are set and evaluated to calculate the risk priority number (RPN) to prioritize the selection of the breakdown causes that need to be improved. It is found that the current availability increased by 1.47% and the amount of breakdowns cost in power generation decreased by 79%.
