Efficient and effective pharmaceutical inventory management is crucial to ensure the availability of drugs in pharmacies and minimize operational costs. Permata Satu Pharmacy in Sumedang Regency previously encountered challenges in managing drug inventory due to fluctuating demand and the absence of a suitable inventory management system. This resulted in increased storage costs and potential stockouts or overstocking. This research aims to develop an improved drug inventory control model utilizing the Multiple Items Economic Order Quantity method. The initial step involved classifying drug items using the ABC analysis. Results indicate that category A comprised 239 items (30.06%) contributing to a total revenue of Rp 390,009,500 (80%), category B included 217 items (27.30%) with a total revenue of Rp 73,391,033 (15%), and category C consisted of 339 items (42.64%) with a total revenue of Rp 24,545,125 (5%). Drugs in category A, which contributed the highest revenue, were prioritized for inventory management, and Economic Order Quantity (EOQ) calculations were performed. Subsequently, a multiple items EOQ inventory control model was implemented to determine the optimal order quantity for drugs, aiming to minimize total inventory costs. The findings revealed that the EOQ model with Single Order Multiple Items and varying order frequencies yielded the lowest annual total cost at Rp 5,063,935. Of the 239 items in category A, 123 items with high demand were ordered five times per year, while 116 items with low demand were ordered 2.5 times per year. Furthermore, the implementation of reorder points and safety stock ensured timely replenishment, preventing stockouts or overstocking. This research demonstrates that the application of the Multiple Items EOQ method, preceded by ABC analysis and followed by safety stock and reorder point calculations, can effectively address drug inventory management challenges while minimizing costs.
