ANALYSIS OF PURE ARGON GAS INVENTORY CONTROL USING MATERIAL REQUIREMENT PLANNING (MRP) METHOD AT PT NOV PROFAB INDONESIA

Abstract

The purpose of this study is to determine the planned amount of inventory and see the level of efficiency before and after using material requirement planning (MRP) with the lot for lot (LFL) technique on pure argon gas. This study uses quantitative research with the MRP approach. Data collection is carried out by means of documentation taken from the company's historical data from 2022 - 2024. The data collected is then processed to calculate storage costs and ordering costs. The results will be used for the calculation of Material Requirement Planning (MRP). MRP calculations are used to determine the amount of gas needed and the costs incurred, as well as to compare costs before and after the implementation of MRP. The results of the study show that the use of material requirement planning (MRP) can determine the planned amount of inventory needed and has proven to be efficient in its use for gas supplies at the NOV Profab Indonesia company.
