Abstract : In the implementation of inventory, the company's purchase of raw materials is still based on the number of requests from customers. Production at PT X occurs when there is an order only not based on regular scheduling. The supply of raw materials for production is only limited to 30 tons / hour per day, but if it is insufficient, no production process occurs or is temporarily stopped. This study aims to compare and analyze the control of raw material inventory costs at palm oil mills in minimizing costs between the company's current policy and if using the Just In Time (JIT) method. One of the goals of Just In Time is to make cost savings so that there is no waste. This study shows that the total inventory costs incurred by PT X at this time are still quite large, namely Rp. 2,096,575,200, while if using the Just In Time method, the total cost of raw material inventory issued is only Rp.1,266,822,846. This means that the company is able to save costs of Rp. 829,752,354. By scheduling and making regular deliveries, the company can reduce the amount of costs incurred.
