ANALISIS BIAYA PENGADAAN MATERIAL PADA PEKERJAAN STRUKTUR PROYEK PEMBANGUNAN FLYOVER GELUMBANG DENGAN METODE MATERIAL REQUIREMENT PLANNING (MRP)

Construction projects frequently face material management issues, such as stockouts (material shortages) and overstock (excess inventory). These problems can lead to cost overruns, delays in work progress, and decreased project productivity. Implementing the Material Requirement Planning (MRP) method with lot-sizing techniques, such as Lot for Lot (LFL) and Economic Order Quantity (EOQ), can help optimize the timing and quantity of material orders. This research analyzed primary data from relevant literature and secondary data from the Gelumbang Flyover Project, including its time schedule, cost estimates (RAB), bill of quantities (BOQ), unit price analysis (AHSP), as well as material unit prices and labor wages. The data processing stages involved developing a product structure, calculating procurement costs, analyzing material requirements, and determining the optimal procurement cost using both LFL and EOQ techniques. The cost analysis revealed that the LFL technique yielded a more optimal total procurement cost compared to EOQ. The total cost using LFL was Rp 45,919,982,716.29, whereas EOQ resulted in a cost of Rp 45,940,186,904.03. The superiority of LFL is attributed to its order quantity, which matches the exact periodic demand, thereby eliminating inventory holding costs despite a higher ordering frequency. In contrast, the EOQ technique, while having a lower order frequency, incurred significantly higher storage costs due to maintained inventory levels.
