Abstract

Maintenance has an important role in the industrial sector as it maintains efficiency and productivity and extends the life of the equipment and machinery used. Mold is one of the important components in the manufacture of mosquito coils where the readiness of the forming and supporting components affects the quality and if damaged will have a detrimental effect on productivity. This research aims to reduce mold breakdown on the 901-line stamping machine so that OEE increases by using a combination of the Fault Tree Analysis (FTA) and Failure Modes and Effect Analysis (FMEA) methods and the Pokayoke method. In the analysis of the FTA and FMEA methods, 7 points were found to cause mold breakdown, including uncontrolled bronbos usage period, loose teflon mold pole lock bolt, worn teflon mold, loose mold shaft lock bolt, worn mold shaft lock bolt, worn endless belt, loose mold nut asbolt. The result of the development of the Pokayoke method, which changes the round end face of the mold shaft to a square one, is an error-proof design. With a square mold shaft end, the mold can be mounted directly to the cross section of the mold post, which is also square, without the need to rotate the machine to change its position.
