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

The local-brand mineral water industry faces intense market competition with the national mineral water industry. In order to be competitive, the local-brand mineral water industry must make various efficiency efforts to reduce production costs, including by planning short product distribution channels. CV. XYZ is a mineral water distributor company in Jember Regency which is also required to make efficient product distribution routes. The purpose of this research is to optimize to determine the shortest distribution route in order to save on the cost of distributing mineral water products. The method used is the Traveling Salesman Problem (TSP), namely the Nearest Neighbor and Cheapest Insertion Heuristic (CIH) methods. The two methods differ only in the exploration program, where Nearest Neighbor explores from any adjacent point, while CIH explores from a certain point and then traces through sub tours to find the shortest route. Based on the survey results, the distribution route currently covers the longest distance of 106.1 km. With the Nearest Neighbor method, the route can be shortened to 72.34 km with a distance saving percentage of 31.82% from the initial route. Meanwhile, the Cheapest Insertion Heuristic (CIH) method produces a total distance of 72.14 km with a distance saving percentage of 32.01%. Fuel savings with the first method of Rp. 1,043,184 while the second method is Rp. 1,049,376. These results indicate that the TSP method can help companies shorten time and save distribution costs.
