Abstract

Quality is important for a product so that it can have more value than other products. To maintain quality, quality assurance (quality) is required. As is the case with silencer products produced by CV. Nyoto Plastik, silencer is a product that must maintain its quality value. Therefore, many defects in silencer products must be repaired by analyzing the causes of the defects. Based on research, the average defect in this silencer product reaches 10% within one year. New Seven Tools is a method for finding out the causes of defects based on humans, methods, materials, machines or the environment by using the seven tools contained in it. Therefore, this research aims to help maintain the quality of silencers by analyzing the causes of defects and providing suggestions for improvements to minimize defects that occur using the New Seven Tools method.

Abstract

Demand is an asset whose value fluctuates. The number of requests can increase or decrease according to consumer wishes. To overcome this fluctuatuing demand, appropriate supplies of raw materials are maintained. Therefore, to calculate inventory can use the EOQ method. PT. MNO is company that operates in marine products. In dealing with raw material supplies, PT.MNO still uses old calculation methods. This research aims to analyze the optimal number of order, the amount of safety stock, reorder points, and compare the costs incurred by the company with the costs calculated based on the EOQ method. The type of research used primary data obtained through field observations. Based on the research results, the costs calculated based on EOQ are lower than the costs incurred by the previous company, in 2022 is Rp. 622.410 and 2023 is Rp. 352.868.
