Analysis of productivity improvement in hard disc spare parts production machines based on OEE, FMEA, and fuzzy value in Batam

摘要

Increasing productivity is very important for companies to achieve success in their business processes. The company studied in this study was in Batam, a manufacturing company engaged in the manufacture of plastic products. The purpose of this study was to determine the value of OEE from machines that produce Hard Disc Drive products in order to increase the effectiveness of the machine. Knowing the main root causes that often occured damage to the machine and to find out how to solve problems that can increase machine productivity. This study uses the Overall Equipment Effectiveness (OEE) and Fuzzy Failure Mode and Effects Analysis methods. The results of the calculation and discussion get the OEE (Overall Equipment Effectiveness) value for April 2018, which is 63.87%. The difference in OEE values obtained is still below the standard value of the OEE classification that makes OEE not reach the target. The main cause of damage to DC machines is 60 tons, namely the low Performance Rate with an average value of 71.71%, this is due to the value of Reduced Speed Losses which has the largest contribution in the six big losses (losses) with a loss of 91.97 the clock which resulted in a DC 60 ton machine not working optimally. The FRPN value of 277 was obtained in the DC 60 ton machine factor so that repairs were needed.
