One of the products produced is Fuji seat, based on the data collected there are 3 parts of the process. The 3 parts of the process are repair 1, repair 2, repair 3. With each there is a check parts & packing table. The method used in companies to manage raw material inventories is still conventional, namely by making continuous purchases without estimating according to needs. So that there is often an excess of raw materials or a shortage of raw materials at a certain time, this makes the costs incurred inefficient and often disrupts the production process. A review of the inventory capacity of Fuji Seat products in this study was carried out using the Economic Order Quantity (EOQ) model. The main raw material inventory data used is Fuji Seat in the 2016-2019 period. Holding cost raw materials is set by PT.
