Abstract
PT XYZ is a manufacturing company engaged in the production of plastic sacks. Delays and shortages of raw materials can disrupt production activities, increase operational costs, and cause production downtime. This study aims to determine the most suitable raw material inventory control method for plastic sack production using Material Requirements Planning (MRP) with Economic Order Quantity (EOQ) and Silver Meal Heuristic approaches. The research process began with demand forecasting to predict future raw material requirements, followed by the calculation of safety stock, reorder point, and the application of EOQ and Silver Meal Heuristic methods to determine the optimal order quantity and timing. The results showed that the total inventory cost using the EOQ method was IDR 216,740,485, while the Silver Meal Heuristic method resulted in a total inventory cost of IDR 504,676,144. Based on these findings, the EOQ method was selected because it generated lower inventory costs and was more suitable for relatively stable raw material demand and the company's limited warehouse capacity. The study also identified operational losses due to production and labor downtime amounting to IDR 360,000 caused by delayed raw material deliveries. In addition, a web-based SMART-MRP system was developed and equipped with forecasting, safety stock, reorder point, EOQ, and MRP features to assist the company in invent
