Abstract

Maintenance of production machines is the key to success for increasing the efficiency of production machines. The value of OEE (overall Equipment Effectiveness) is an important indicator of the level of effectiveness of production machines. The grinding machine at the cocoa powder company PT ABC Sidoarjo is a production machine that is considered to have the greatest contribution to achieving OEE values. However, up to now, the machine maintenance is only corrective so it has the potential to harm the company. The purpose of this study is to determine the effectiveness of the grinding machine and formulate recommendations for improvement. The method used is the six big losses analysis technique to identify the dominant type of loss, and the FTA (Fault Tree Analysis) technique to determine the root cause. The results of the analysis show that the OEE value of the grinding machine is only 45% (low). The types of losses that contributed greatly to these conditions were reduced speed losses by 41% and were categorized as bad. This is due to the absence of regular replacement of the grinding machine blades so that their performance is less stable. In addition, the values of idling and minor stoppages and set up and adjustment losses are also categorized as bad because of the frequent occurrence of wasted processing time. Only rework losses are categorized as good. A low OEE value indicates that the machine is still not working effectively. Recommendations for improvements that can be done are performing independent maintenance, forming a competent small group, arranging planned maintenance for replacing machine blades and installing vibrators on peripheral pipes

Abstract

One of the subsidiaries of PT Perkebunan Nusantara XII is PT Rolas Nusantara Mandiri (PT RNM). This company is a producer of quality coffee products and was established in 2007, which in terms of experience in processing and managing coffee sales systems is beyond doubt. Packaging workers in the UKB PT RNM complained about the lack of comfortable work facilities and also pain in certain parts of the body. The purposes of this research are to analyze the work posture of packaging workers at UKB PT RNM, analyze the risk level of complaints of musculoskeletal disorders (MSDs) at UKB PT RNM, and design packaging station work facilities according to anthropometric data processing and QFD methods. The data processing stages in this research include processing NBM worksheet data, REBA, then processing QFD data, then processing anthropometric data, and work facility dimensions. The anthropometric data was first tested for data adequacy and uniformity and then redesigned the work facility design with new design dimensions. The results of this research include the results of the NBM, complaints of moderate pain were 77.97%, complaints of pain were 6.78%, and complaints of very pain were 15.25%. Dominant complaints of pain in the neck, wrists, fingers, back, waist, buttocks and thighs. Then the REBA results showed that the three packages of Mount Ijen coffee were included in the very high-risk level category. Work facility design redesign was carried out on work chairs and sliders. Chairs are made to have soft seat backs and cushions and sliders are more practical.
