Raw material inventory plays an important role in the smooth operation of a company, but inefficient management can cause wasted costs and disrupt the production process. The EOQ method is used to determine the optimal order quantity, so as to reduce storage and ordering costs for raw materials. The data used in this research was obtained through direct observation, interviews with business owners, and analysis of raw material purchase documents.

The research results show that the application of the EOQ method at Rumah Kopi Baik has succeeded in reducing storage costs and reducing order frequency. The total cost savings achieved are more significant compared to previously applied conventional methods. Implementing EOQ at Rumah Kopi Baik not only increases operational efficiency, but also has a positive impact on the company's profitability.
