Analisis Penerapan Material Requirement Planning (Mrp) dengan Mempertimbangkan Lot Sizing dalam Pengendalian Persediaan Kebutuhan Bahan Baku Xoly untuk Pembuatan Alkyd 9337 pada PT. Pjc

Abstract

[Application Analysis of Material Requirement Planning Considering Lot Sizing in Inventory Control for Raw Material Needs (Xoly) for Making Alkyd 9337 in PT. PJC] PT. PJC is one of the companies producing synthetic resin in Indonesia with a current production capacity of 46,110 tons / year, production produced is a semi-finished materials. One of the raw materials that have a problem is xoly. The raw material used to produce Alkyd 9337. The problems that occur in the raw materials xoly is the company booked too many raw materials that do not suit it needs. It certainly lead to overstock raw materials in the warehouse and demanded the company must pay more for storing raw material. The method used for this problem is the lotting from Material Requirement Planning (MRP) method. Based on calculations with 9 existing MRP method is obtained that Wagner Within Algorithm WWA results obtained Rp 3,416,073,100. WWA method is an optimal solution for booking a deterministic number of units during a specified time horizon
