School bag company types of raw materials including polyester, canvas, synthetic leather, foam, and supporting accessories. Based on the company's historical data, it was found that raw material overstock conditions in several periods with excess inventory ranging from 30%–35% of actual production needs. This condition has the potential to increase storage costs, tie up working capital, and reduce the quality of raw materials due to excessive storage. This study aims to analyze the overstock conditions of all raw materials based on the Bill of Material (BOM) structure and plan material requirements using the Material Requirement Planning (MRP) method with the Lot Sizing Lot For Lot (LFL) technique. The data used include the Master Production Schedule (MPS), BOM, initial inventory, scheduled receipts, and supplier lead times. The results of the study indicate that the implementation of MRP is able to reduce overstock conditions in all raw material components
