Economic Production Quantity (Epq)Di Pt Likuid Pharmalab Indonesia (PT LKPI)

The Economic Production Quantity (EPQ) model aims to minimize production inventory costs by minimizing inventory costs. The component of "production-cost of production" (TIPC) according to EPQ theory is composed of components of costs: 1) production costs; 2) setup costs, 3) saving costs; and 4) shipping costs. However, in reality, the company not only has a continuous demand, but also has a discrete demand whose fulfillment is in a certain time interval. PT Likuid Pharmalab Indonesia (PT LKPI) as a manufacturer of medical devices and household health supplies has two types of demand. This research uses the calculus method. From the results of quantitative calculations using the EPQ method, it is obtained the optimum delivery time (T) of 13 days with a frequency of delivery (m) 2 times per cycle, the cost of production inventory is Rp. 22,093,072,258.1. With the delivery time that has been used by the company T 14 days and 1 times, the production inventory cost (TIPC) is Rp. 22,505,185,180.6. So compared to the EPQ method, there is a decrease in production inventory costs (TIPC) of Rp. 412,112,922.5 or saving 2%
