Improved YM Laser Machine Performance with Overall Equipment Effectiveness and Fault Tree Analysis Methods Implementation at PT. XYZ

Abstract

Abstract In the development of the shoe-making industry, demanding companies continue to improve the quality and quality of production. PT. XYZ responded by improving the performance of the YM Laser machine which is the main engine in the sports shoe production line. The approach is carried out using the entire Equipment Effectiveness Method and Error Tree Analysis. The purpose of this study is to measure the ratio of value availability, performance ratio, quality ratio, total value of OEE on YM Laser machines, identify the root causes of problems and make improvement plans to improve machine performance. YM Laser Machines have a Overall Average Equipment Effectiveness Value of 75.89%. After researching with the OEE method, it was found that the root of the problem was to reduce speed. Furthermore, the investigation using a cause and effect diagram, obtained the main cause is a machine factor. All problems found were solved using Fault Tree Analysis on engine factors and their improvement efforts to make standard lens replacement so that the lens is always in optimal condition, changing the quality of the switch so that it is not easily damaged again, and regularly updating software and replacing standard bolts.
