P T. Ebara Indonesia is the first domestic manufacturer of water pumps inIndonesia, which was established in 1980 in Jakarta. The study was conducted in GSMoulding line on PT. Ebara Indonesia. GS Moulding Line is used to change sand mix,bentonite, coal and sea water into components or parts of the water pump framework,such as: casing cover, bearing housing and the impeller. The main problem inmaintenance is the occurrence of breakdown because of the damage of the engine or theengine components, thereby it is disrupting the production process and lead to reducingavailable production time and it cause the reduction of the production output at the end.The purpose of this study is to give a suggestion of the engine’s repairmen andmaintenance by using Total Productive Maintenance (TPM) on GS Moulding’s line.This study uses Total Productive Maintenance (TPM) approach as a solution tosolve the problems. Based on the calculation of Overall Equipment Effectiveness (OEE),it was found that some of the value on OEE during the research period is still below worldclass OEE which equals to 85%. Based on the identification result of six big losses, thebiggest losses is caused by reduced speed with 78.67 percent. The next stage is to makeFault Tree Analysis diagram (FTA) to determine the source cause of the damage and theprobability of failure. Based on the calculation result of the failure probability, it wasobtained that conveyors component, bucket elevators, bucket mixer and the hopper arethe components that have high probabilities of failure.The improvement proposed for handling breakdown problems based on eightpillars of TPM by focusing on the pillars of autonomous maintenance, plannedmaintenance, and education & training. The improvement proposal of this study isperforming calculations in determining the preventive maintenance schedule formaintenance, creating autonomous maintenance SOP, and give some trainings forproduction operators.
