The company where the author conducted research is a company engaged in the automotive sector that produces various seals for motor vehicles and heavy equipment. The raw material used is rubber (synthetic rubber). This company has difficulty determining the amount of Rubber inventory by the needs so that there is no excess inventory stock that can cause excess inventory costs. The method used in this research is Economic Order Quantity (EOQ) and Just In Time (JIT). The author intends to compare the two methods to the cost efficiency of raw material inventory and choose which method is more appropriate for this company. From the research, it is known that the inventory costs incurred by the company are Rp. 6,048,000, while the result of the cost calculation using the EOQ method is Rp. 3,678,175 and Rp's JIT method. 1,320,945. It can be concluded that the JIT method has the smallest total cost of inventory compared to the EOQ method and the company method.
