Abstract

This research was conducted in a factory that produces polypropylene, polyethylene, and high density plastics located in North Sumatra Province, Indonesia. Based on the characteristics of its products, the company implements a make to stock system. However, the products experience quite high damage reaching 20% ​​of its total production. Therefore, this study will analyze the causes of defective products during storage in a plastic factory. In this study, historical data of damage that occurred and Pareto Diagram were used to obtain the main causes and analyze them so that defective products when stored in the warehouse can be reduced. Based on the Pareto Diagram, it was found that sticky and discolored plastics dominate the number of defective products. To prevent this, it is necessary to manage the temperature of the storage room, provide a good understanding for operators and inspect materials according to standards

Therefore, the Standardization and Industrial Services Center (BSPJI) Medan as a public service unit that has a Product Certification Agency (LSPro) is needed. The problem is the length of the LSPro BSPJI Medan service process to complete the company's SPPT SNI starting from the application until the issuance of the SPPT SNI. This causes losses for business actors both in funds and time. The purpose of this study is to provide suggestions for improvement and optimize time by maintaining value-added activities and reducing non-value-added activities. The methods used are Lean Service, Waste Analysis and for design using the FVSM Method. The results showed that there was waste that occurred in the LSPro BSPJI Medan service.
