Pengendalian Persediaan Bahan Baku Batu Bara Menggunakan Metode Min-Max Di PT. XYZ

Abstract

Inventory is an important factor in carrying out a production. Many companies experience problems in terms of inventory control, one example is inventory scarcity. The purpose of this study is to optimize the need for goods so that the company will not experience problems with inventory shortages or inventory buildup. This study uses  the Min-Max method  by collecting data in the form of inventory of goods needs, ordering costs, and storage costs. The result of this study  is that the safety stock value  of 80,887-tons is useful for protecting and anticipating inventory shortages, so companies must be on guard when they are at that value. Then, the Reorder Point value was obtained at 108,165 tons. Furthermore, the value of the Minimum Inventory  is 269,879-tons and the Maximum Inventory is  378,044-tons so that companies are not recommended to have more inventory than that value.
