IMPROVEMENT OF WAREHOUSE LAYOUTUSING DEDICATED STORAGE METHOD TO OPTIMIZE STORAGE UTILIZATION OF AUTOMOTIVE COMPONENTS AT PT XYZ
The warehouse has a very important role in the supply chain network to distribute products to consumers. PT XYZ warehouse uses a rack system to store products before they are distributed to the production process. The problem faced is that the placement of products is scattered and irregular depending on the conditions in the field, products that come are placed in empty places which can cause the storage space to become larger so that the warehouse capacity has not been fully utilized with a utilization rate of 105% and causes a decrease in the actual warehouse capacity. It’s necessary to rearrange the placement of products in the storage location to optimize the utilization rate of storage space, with the dedicated storage method. This method is to solve the problems that occur in the warehouse layout which includes product placement in the warehouse by placing only one type of product in one storage room. In this method product storage is more organized, it will be stored in a fixed location. The total storage slot requirement for each product is 19 slots and the highest T/S value is 2.32 activities/slot, and these products are prioritized for storage placement near the warehouse entrance and exit to optimize storage space utilization. The results of the application of the dedicated storage method obtained a storage space utilization rate of 100%, while in the existing condition it was 105% with a percentage decrease of 5%.

This observation aims to identify the types of defects that occur in the powder packaging process at PT. XYZ as an effort to improve product quality. By doing this observation, the benefits obtained include being able to find out what problems cause disability and be able to overcome these defects from the suggestions given by observers. The multi lane machine is a packaging machine that is the object of observation because in the packaging process on this machine there are still many defective products produced. The method used in this observation is Six Sigma with the DMAIC approach which consists of the Define, Measure, Analyze, Improve, Control stages. The results of data processing show that the sigma level value is 4.10, which means that the quality control process carried out by the company has been running well. However, more intense control still needs to be needed to minimize the possibility of defects. The causative factors that cause leakage defects in the primary packaging of xyz powder include four factors, namely Human, Machine, Method and Material factors. Then from the four factors, suggestions for improvement are given.
