Abstract

PT. MTUI is a manufacturing company engaged in the production of gas cylinders. One critical aspect of its operations is inventory management. PT MTUI faces challenges in managing the inventory of its main raw material, Steel Plate. Issues of stock shortages or surpluses frequently occur due to a suboptimal inventory control system, which can disrupt production flow and lead to delays in order fulfillment. To address this, an analysis was conducted using the Economic Order Quantity (EOQ) method to determine the optimal procurement policy. The results show that the optimal order quantity for Steel Plate is 261.37 tons with an order frequency of 17 times per year. Additionally, a safety stock of 712 units and a reorder point of 1,226 tons were established. Financially, the previous procurement cost amounted to Rp5,331,083, while the EOQ method reduced the cost to Rp3,983,185. This resulted in savings of Rp1,347,898, demonstrating that EOQ implementation not only enhances inventory efficiency but also significantly reduces operational costs for PT. MTUI. Keywords: EOQ, Inventory, Procurement, Safety Stock, Total Inventory Cost
