Analysis of Rice Inventory Control Using The Silver Meal and Economic Order Quantity Method: Case Study of Perum Bulog Kolaka Regency

Abstrak

This study aims to analyze rice inventory management at Perum Bulog Kolaka and to compare the effectiveness of the Economic Order Quantity (EOQ) and Silver Meal methods in ensuring optimal logistics availability. The research employs a quantitative approach by analyzing demand data, ordering costs, and holding costs. The results indicate that the EOQ method produces an optimal order quantity of 849,000 kg per cycle with a purchasing frequency of 36 times per year. The associated costs include an ordering cost of IDR 11,340,892 and a holding cost of IDR 90,725,756. Meanwhile, the Silver Meal method results in a total inventory cost of IDR 10,555,555, calculated based on the average cost per period. However, the EOQ method is proven to be more efficient in inventory control as it determines an optimal order quantity and is supported by a safety stock of 8,163 kg, thereby minimizing the risk of stockouts. Furthermore, the implementation of the EOQ method is capable of reducing total inventory costs significantly by up to IDR 289,345,727 per year compared to the previously applied method. Therefore, the EOQ method is recommended as a more effective approach for rice inventory management at Perum Bulog Kolaka.
