Abstract

The manufacturing company in this study is a company engaged in the automotive sector that produces pistons and non-pistons. The problem that occurs in the company is that the average percentage of defects exceeds the company's standard limit of 5% while the maximum defect limit is set by the company at 1%. Identify the dominant type of defect, identify the biggest factors causing the dominant type of defect and make suggestions for improvement. In this study using the DMAIC method (Define, Measure, Analyze, Improve and Control) in the production process of the type x gasoline piston, there are several types of defects, namely monoiri, misrun, coating loss. The types of defects that occur are based on the Pareto diagram, namely the type of defect monoiri with a percentage of 56%, misrun 28% and coating loss 16%, and the causal factors are known using a fishbone diagram, there are 5 factors, namely material, people, methods, machines and environment. Based on the results of the identification of FMEA and the calculation of the highest RPN, it is known that the monoirritic defects that occur in the causative factor of the material with an RPN value of 175. For proposed improvements, namely monitoring and creating monitoring forms to facilitate cleaning of materials on a scale, and to facilitate cleaning of larger materials. scheduled.
