Abstract

Each company wants to improve the efficiency of the production process so that it can compete in terms of price and quality with other companies. The company that is the object of this research is engaged in electronics manufacturing. The problem that occurs is the difference in production results between the company's target and the reality that occurs, with an indication of a decrease in the effectiveness of production machines. The highest reduction in machine effectiveness occurred in primary winding machines. The purpose of this research is to measure the value of the effectiveness of the primary rolling machine using the overall equipment effectiveness (OEE) method and six big losses. Furthermore, to analyze the factors that are the main priority as a basis for improvement proposals to increase production efficiency using a causal diagram. In the calculation, OEE measures effectiveness with 3 points of view, namely availability, performance, and quality. To determine the decrease in machine effectiveness, the six big losses method was used. The results showed that the average effectiveness level of the primary rolling machine during the study period was 80.7%, with an average value of 97.75% availability, 68.15% performance, and 99.65% quality. Meanwhile, the one that most affected the decrease in the effectiveness of the primary rolling machine was reduced speed losses.
