Analysis of total productive maintenance (TPM) implementation using overall equipment effectiveness (OEE) and six big losses: A case study

Abstract

In improving the productivity of the machine, the management of the decision or maintenance policy must be appropriate. In Spinning II unit at PT Apac Inti Corpora, there are 124 ring frame machines that often have breakdown and cause a high downtime so that the production target is not achieved, so this research was conducted on the ring frame machine. This study aims to measure the value of equipment effectiveness, find the root cause of the problem and provide suggestions for improvement. This research begins with measuring the achievement of overall equipment effectiveness (OEE) value, then identifying the six big losses that occur. The results show that the average value of OEE in the ring frame machine is 79.96%, the effectiveness value is quite low because the standard of OEE value for world class company ideally is 85%. The biggest factor that influences the low value of OEE is performance rate with percentage factor six big losses at reduced speed losses of 17.303% of all time loss. Proposed improvement actions are the application of autonomous maintenance, providing training for operators and maintenance technicians and supervising operators in the workplace.
