Abstract

Salah satu faktor yang memengaruhi kelancaran dalam pelaksanaan suatu proyek konstruksi adalah aliran material saat pelaksanaan. Keterlambatan datangnya material konstruksi yang menyebabkan stockout persediaan material saat akan digunakan membuat pekerjaan menjadi tertunda. Hal ini secara tidak langsung dapat memengaruhi total waktu pelaksanaan serta biaya proyek. Tugas akhir ini bertujuan untuk menganalisis persediaan material (inventory) pada Proyek Kompleks Pasar Tradisional dan Plasa Lamongan. Analisis persediaan material dalam tugas akhir ini dilakukan dengan metode MRP. Dalam metode MRP, proses analisis melalui tahap gross material requirements plan (rencana kebutuhan kotor), netting (analisis kebutuhan bersih), lotting (analisis jumlah pesanan), dan explosion. Pada tahap lotting digunakan empat teknik, yaitu Lot for Lot, Economic Order Quantity, Period Order Quantity, dan Part Period Balancing untuk mendapatkan jumlah pesanan optimum dan membentuk biaya persediaan minimum. Dari hasil analisis MRP yang dilakukan, didapat bahwa teknik lotsizing yang membentuk biaya persediaan minimum untuk tiang pancang, Beton K-300, batako, besi D16, dan besi D19 adalah teknik Lot for Lot, Period Order Quantity, dan Part Period Balancing. Teknik lotsizing dengan biaya minimum untuk Semen Portland dan besi D10 adalah teknik Lot for Lot, sedangkan teknik lotsizing dengan biaya minimum untuk pasir pasang adalah teknik lotsizing Period Order Quantity dan Part Period Balancing. Total biaya persediaan material minimum untuk tiang pancang Rp. 568.837.200,00; Beton K-300 Rp. 55.384.200,00; batako Rp. 16.174.800,00; Semen Portland Rp. 4.322.740,00; pasir pasang Rp. 2.698.560,00; besi D10 Rp. 34.337.800,00; besi D16 Rp. 100.508.670,00; dan besi D19 Rp. 71.811.450,00.

One of the factors that affects the smooth implementation of a construction project is the flow of materials during construction. Delays in the arrival of construction materials that cause material inventory stockouts when the materials are needed result in work delays. This can indirectly affect the total implementation time and project costs. This final project aims to analyze material inventory in the Traditional Market Complex and Plaza Lamongan Project. The analysis of material inventory in this final project was performed using the MRP method. In the MRP method, the analysis process involves the stages of gross material requirements planning, netting, lot sizing, and explosion. At the lot-sizing stage, four techniques are used: Lot for Lot, Economic Order Quantity, Period Order Quantity, and Part Period Balancing, to obtain optimum order quantities and minimize inventory costs. The results of the MRP analysis show that the lot-sizing techniques that result in minimum inventory costs for piles, K-300 concrete, concrete blocks, D16 steel bars, and D19 steel bars are Lot for Lot, Period Order Quantity, and Part Period Balancing. The lot-sizing technique with the minimum cost for Portland cement and D10 steel bars is Lot for Lot, while the lot-sizing techniques with the minimum cost for bedding sand are Period Order Quantity and Part Period Balancing. The minimum total material inventory costs are Rp. 568,837,200.00 for piles; Rp. 55,384,200.00 for K-300 concrete; Rp. 16,174,800.00 for concrete blocks; Rp. 4,322,740.00 for Portland cement; Rp. 2,698,560.00 for bedding sand; Rp. 34,337,800.00 for D10 steel bars; Rp. 100,508,670.00 for D16 steel bars; and Rp. 71,811,450.00 for D19 steel bars.
