XX Milk distributors face the bullwhip effect, which is fluctuations in excess demand due to inaccurate information and a suboptimal ordering system, causing stock inefficiency. This study aims to minimize the bullwhip effect on XX Milk Distributors by applying the Economic Order Quantity (EOQ) method. The research uses a quantitative approach with an explanatory design. The data used includes demand and sales of SGM Eksplor milk from five major retailers in Bekasi during the period from May 2022 to April 2023. The analysis techniques used include the calculation of the variance coefficient to measure the bullwhip effect before and after the implementation of EOQ, as well as inventory cost analysis. The results showed that the implementation of EOQ succeeded in reducing the bullwhip effect by 11% and optimizing inventory costs with an average savings of 1.24%.Although the EOQ method is effective in reducing demand fluctuations, this study recommends the implementation of additional strategies such as Collaborative Planning, Forecasting, and Replenishment (CPFR) and Vendor-Managed Inventory (VMI) to improve supply chain stability. In addition, the integration of artificial intelligence-based technologies can improve the accuracy of demand forecasting. With a more holistic strategy, supply chain management can become more efficient and adaptive to changing market demand. Keywords: Bullwhip effect, Economic Order Quantity, Supply chain
