Analysis of Double indian Ballbreaker Net Sorter Machine Based on Overall Equipment Effectiveness Method Cases in Tea Plantation Plants

摘要

In a factory, the position of the production machine plays an important role because if the engine is damaged it will disrupt the production target. This study analyzes the performance of Double Indian Ballbreaker Net Sorter (DIBN) machines, one of the machines used to produce orthodox tea which in the fact, this machine often damaged and has high downtime. This leads to a low level of machine availability in the Production Department. For that, we need an Overall Equipment Effectiveness (OEE) method to measure the performance and the level of effectiveness of the machine and six big losses factor analysis to find out what factors cause low of OEE value. Based on the OEE calculation results, the value of OEE DIBN machine is 53.98%. The result is still far from the standard set by the Japanese Institute of Plant Maintenance of 85%. From six big losses, it is known that the most influencing factors to decrease the effectiveness of DIBN machines are rework losses (23.33%), reduced yield losses (20.17%) and reduced speed of 19.49%.
