Inventory control of premix plastic is a major operational challenge for PT XYZ. Despite its status as a production auxiliary material, the lack of a measurable ordering method results in recurring stockouts. To overcome this problem, the research applies the Economic Order Quantity (EOQ) method. The calculation results show adjustments to the order quantity to make it more efficient. Previously, the average order for 25x45 cm plastic was 325 kg, which was then optimized to 400.58 kg per order. For the 40x60 cm plastic size, the average actual order of 450 kg was adjusted to 466.15 kg. By integrating a Safety Stock of 100.46 kg for 25x45 cm plastic and 136.12 kg for 40x60 cm plastic, as well as a Reorder Point of 316.68 kg for the 25x45 cm plastic and 429.10 kg for the 40x60 cm plastic, the company now has systematic inventory protection. The application of this proposed method is not only able to prevent stockout risks but also results in savings in Total Inventory Cost (TIC) of 2.14% for 25x45 cm plastic and 0.06% for 40x60 cm plastic compared to the actual policy.
