IMPLEMENTASI METODE EOQ DAN POQ PADA PENGENDALIAN PERSEDIAAN BAHAN BAKU ALAT UJI KESEHATAN PT. X

Abstract

Manufacturing companies essentially transform raw materials into finished products through various production operations. This research aims to evaluate the inventory control of raw materials for health diagnostic test device products (HBSAG & HIV) at PT X. The method used is Material Requirement Planning (MRP) with lot sizing techniques using EOQ and POQ methods. The calculated actual inventory costs for the company are Rp 25,357,043 (HBSAG) and Rp 23,973,320 (HIV). The research results using the EOQ lot sizing method show reduced costs to Rp 17,486,791 (HBSAG) and Rp 13,243,617 (HIV). Meanwhile, the POQ lot sizing method yields inventory costs of Rp 16,403,312 (HBSAG) and Rp 12,556,514 (HIV). In the final analysis, the most optimal inventory control method is the Period Order Quantity (POQ) method, as it can save inventory costs by Rp. 8,953,731 (HBSAG) and Rp. 11,346,116 (HIV) annually.
