Steel Agent Welding Workshop is a business engaged in welding services with a focus on manufacturing and assembling iron-based products. There are significant losses due to waste in the production process, which encourages the need for inventory cost efficiency. This study aims to determine the efficient control of raw material inventory using the Just In Time (JIT) method. A quantitative descriptive method is used, including the calculation of the total cost of inventory. The results showed that JIT streamlined inventory costs from Rp2,475,215 to Rp931,378, saving Rp1,543,837. The total savings reached Rp9,324,837, consisting of cost efficiency and waste reduction of Rp7,781,000. The implications of this study provide suggestions to management to review existing inventory control methods.
