PT Apparel One Indonesia implements raw material inventory control system closes to JIT concept which is based on the buyer's order. This concept is used by the company with the consideration that it can minimize the inventory costs. The company enhances only 10% of total quantity to cover the demand of sample product. But the fact, the application of this method does not work well due to the delay of raw material arrival which disrupts production process. The company has to alternate the shipment mode of importing raw material from maritime to airline and it does not spend a little cost. This study aims to forecast the polyester usage for the following 12 months and to find out the suitable method of imported raw material inventory control in PT Apparel One Indonesia by comparing and analyzing the implementation of JIT concept and EOQ method as well as to determine the safety stock and reorder point in inventory procurement of the company. The data used in this study are secondary data of 2015-2016 obtained from the company. Polyester becomes the imported fabric raw material which observed due to the main fabric raw material. The polyester usage predicted by regression is continuously increases per month. The forecasting result can be accepted because the tracking signal value is not more than ± 4. Whereas, EOQ method is more suitable to be used by the company since the inventory cost is lower than the cost applying JIT concept. It is possible to save 13% or 9,512,693.3 IDR. Moreover, by applying EOQ method, it also determines the reorder point (ROP) and safety stock inventory to guarantee the smoothness of production activities. The company can purchase raw materials when the quantity of inventory which is available in warehouses amounted to 375.547 yards (ROP), while the safety stock of polyester fabric is 43,006yards.
