PT Kimia Farma, Tbk. is a publicly owned company (BUMN) which undertakes the business in the Pharmaceutical Industry. PT Kimia Farma, Tbk. has six production units, one being PT Kimia Farma Plant Banjaran which is located in the area of Bandung Regency of West Java. In the course of its operations, there is a need to procure raw materials and packaging materials to PT Kimia Farma Plant Banjaran produces enough products to meet customer requests. However, there is a challenge of too much stock in hand on most occasions for instance in the case of raw materials and packaging materials. This stock up is aggravated by the fact that most of these materials are perishable and have a set period to be used within. Thus, any element of stock which has exceeded its use by date is classified as expired stock, cannot be utilized in any production activities as well as meeting any thorough usage. In this case, the purposes of the research are to analyze inventory control for raw materials and the packing materials taking their shelf life into consideration at PT Kimia Farma Plant Banjaran. The conceptual framework of the research used a combination of the Shelf Life Adjustment Model Q by Hidayat & Fauzi (2015) and Perishable Inventory Adjustment Model by Muriana (2016) using both the Original and Revised Algorithms. As the main activity of this research, the expected total inventory costs includes purchasing costs, ordering costs, shortage costs, and expiration costs. From the study conducted at PT Kimia Farma Plant Banjaran, the proposed model for raw materials is the Revised Algorithm of Muriana’s Adjustment Model (2016), which provides a saving of 45.06% in expected total inventory costs (from IDR 1,974,479,087,155 to IDR 1,084,804,352,512) and an average increase in service level by 10.06% (from 90.43% to 99.53%). Meanwhile, the proposed model for packaging materials is the Revised Algorithm of Hidayat & Fauzi’s Adjustment Model (2015), resulting in a 21.92% saving in expected total inventory costs (from IDR 34,477,907,950 to IDR 26,920,832,513) and an average increase in service level by 3.32% (from 96.56% to 99.77%).
