Abstract

Effective inventory management is vital for companies in competitive industries, particularly in the technology sector, where timely material availability can significantly impact project execution. This paper examines the inventory challenges faced by PT Pratama Persada Teknologi, a contractor in Indonesia's technology sector, highlighting issues of overstocking and stock shortages that lead to high carrying costs and project delays. By applying Material Requirements Planning (MRP) techniques, specifically Lot-for-Lot (LFL), Period Order Quantity (POQ), and Economic Order Quantity (EOQ) methods, this study aims to optimize material inventory control for network installations. The analysis reveals that the POQ method yields the lowest cost for UTP Cat 6 Cable, while the LFL method is optimal for Patch Cord Cat 6. For Modular Jack Cat 6, both LFL and POQ methods are cost-effective. Implementing MRP not only provides critical scheduling and reordering information but also minimizes delays, enhancing project efficiency and profitability. This research contributes valuable insights for similar companies seeking to improve their inventory management practices and maintain competitiveness in the technology installation market.
