Abstract

Abstrak Salah satu faktor mempengaruhi kelancaran dalam pelaksanaan suatu proyek konstruksi adalah pengadaan material ke lokasi. Keterlambatan datangnya material konstruksi yang menyebabkan stockout persediaan material saat akan digunakan membuat pekerjaan menjadi tertunda. Hal ini secara tidak langsung dapat mempengaruhi total waktu pelaksanaan serta biaya proyek. Penentuan tingkat persediaan yang tepat dapat diaplikasikan dengan mengunakan metode Material Requirement Planning (MRP). Tujuan dari penelitian adalah untuk mengetahui ukuran pemesanan dan biaya pengadaan material yang paling efisien dari dua teknik lotsizing yaitu teknik Period Order Quantity (POQ) dan teknik Economic Order Quantity (EOQ) pada Gedung Laboratorium Kebencanaan Universitas Syiah Kuala (USK) di Kota Banda Aceh. Proses yang terdapat dalam MRP meliputi netting, lotting, offsetting, dan explosion. Metode MRP diterapkan pada proyek Gedung Laboratorium Kebencanaan USK, dengan menghitung jumlah kebutuhan material berdasarkan data Rencana Anggaran Biaya (RAB), Analisis Harga Satuan (AHS), dan jadwal pelaksanaan terhadap 28 (dua puluh delapan) material di lokasi proyek. Berdasarkan dari teknik yang dianalisa, teknik lotsizing yang menghasilkan biaya total paling ekonomis untuk semua material adalah teknik Periodic Order Quantity (POQ) dengan biaya sebesar Rp. 9.850.848.30, Sedangkan yang mempunyai biaya pengadaan material sangat tinggi ditunjukkan oleh teknik EOQ, Rp. 9.852.102.40, artinya biaya yang dikeluarkan lebih kecil yaitu Rp. 1.234.00 (97%). Kata Kunci: Gedung Universitas Syiah Kuala, Material Requirement Planning, Lotsizing, Period Order Quantity, Economic Order Quantity  Abstract One of the factors influencing the continuity running of a construction project is material procurement to the site. The delay in the arrival of construction materials which causes a stockout of material supplies when they will be used makes the work delayed. This can indirectly affect the total implementation time and project costs. by using the Material Requirement Planning method. The purpose of this study was to determine the order size and the most efficient material procurement costs from the two lotsizing inventory control techniques, namely the Period Order Quantity (POQ) and the Economic Order Quantity (EOQ) at Disaster Laboratory Building University of Syiah Kuala in Banda Aceh city. The processes contained in MRP is netting, lotting, offsetting, and explosion. The MRP method is applied to the Disaster Laboratory Building University of Syiah Kuala project, by calculating the amount of material needed based on the Budget Plan data, Unit Price Analysis, and the project schedule which includes its 28 materials. Based on the analyzed technique, the lotsizing technique that produces the most economical total cost for all materials is the Periodic Order Quantity (POQ) technique with a cost of Rp. 9,850,848.30, while those who have very high material procurement costs are indicated by the EOQ technique, Rp. 9,852.102.40, meaning that the costs incurred are smaller, namely Rp. 1.234.00 (97%). Keywords: Building University of Syiah Kuala, Material Requirement Planning, Lotsizing, Period Order Quantity, Economic Order Quantity
