Total Productive Maintenance (TPM) Analysis on Lathe Machines using the Overall Equipment Effectiveness Method and Six Big Losses

Abstract

C.V. Oni Jaya is a company engaged in manufacturing by producing / modifying motorcycle parts. This company is inseparable from problems related to the effectiveness of equipment or machinery. One of the causes of the disruption of the production process is the lack of maintenance management on the machine. Measurement of the level of effectiveness of the machine by using the Overall Equipment Effectiveness (OEE) method, the OEE calculation starts from January 2017 until December 2017. In the data processing, it can be seen that the set up and adjustment factors, Reduced Speed Loss and Breakdown Loss have the largest percentage of the six factors causing losses that affect the effectiveness of the machine. Analysis is done by looking at the cumulative percentage of six big losses factors against the total time loss caused by each factor of the six big losses.
