Raw material inventory is the company\u27s largest investment. So that raw materials must be managed optimally in order to maximize corporate profits. Mismatch in the management of raw materials can affect the smoothness of production, which resulted in cessation of the production process. Excess inventory of raw materials may result in high inventory costs in storing and maintaining these raw materials. This study aims to obtain the needs of optimal raw materials in accordance with production needs. The approach used in this research use deterministic model with Silver Meal method. Using Heuristic Silver Meal in chemical control planning planning in January - July 2015 resulted in total raw material inventory cost less than the total cost of inventory applied by the company. Cost savings of Rp 263,137,813 and total inventory efficiency of raw material needs can be done this is because the quantity pemems done optimal
