    Abstract

    Industri konstruksi memiliki tingkat konsumsi material yang tinggi, di mana baja tulangan menyumbang porsi biaya yang signifikan. Pengelolaan yang kurang optimal dapat menimbulkan waste material yang berdampak pada peningkatan biaya dan limbah konstruksi. Penelitian ini bertujuan untuk menganalisis dan membandingkan hasil optimasi waste material baja tulangan menggunakan Cutting Optimization Pro (COP) dan Excel Solver dengan pendekatan Integer Linear Programming (ILP). Penelitian ini menggunakan metode kuantitatif dengan studi kasus pada Proyek Pembangunan Gedung Perkantoran Bank BTN Soekarno Hatta Bandung. Jenis data yang digunakan adalah data sekunder yang diperoleh dari As Built Drawing, Rencana Anggaran Biaya (RAB), dan Bill of Quantity (BOQ) yang disediakan oleh PT Casa Prima Indonesia. Data tersebut diolah melalui pemodelan 3D menggunakan Autodesk Revit untuk menghasilkan Bar Bending Schedule (BBS) sebagai dasar analisis kebutuhan tulangan. Selanjutnya, proses optimasi pemotongan dilakukan menggunakan dua perangkat lunak, yaitu Cutting Optimization Pro dan Solver Excel, dengan mempertimbangkan variabel kontrol berupa panjang batang, diameter tulangan, kebutuhan potong, serta tipe pemasangan. Hasil penelitian menunjukkan bahwa metode konvensional menghasilkan volume baja tulangan sebesar 182.912,41 kg, sedangkan metode BIM sebesar 181.682,58 kg, dengan selisih 0,67% terhadap volume kontrak. Optimasi menggunakan COP menghasilkan waste sebesar 6,52%, sedangkan Excel Solver sebesar 6,74%. Metode COP memberikan biaya waste yang lebih rendah dengan selisih 5,43% dibandingkan Solver. The construction industry has a high level of material consumption, in which reinforcing steel contributes a significant portion of project costs. Inefficient management may lead to material waste, resulting in increased costs and environmental impact. This study aims to analyze and compare the optimization results of reinforcing steel waste using Cutting Optimization Pro (COP) and Excel Solver with an Integer Linear Programming (ILP) approach. This research employs a quantitative method with a case study on the Bank BTN Office Building Project, Soekarno Hatta, Bandung. The study utilizes secondary data obtained from As-Built Drawings, the Bill of Quantity (BOQ), and the Budget Plan (RAB) provided by PT Casa Prima Indonesia. The data were processed through 3D modeling using Autodesk Revit to generate a Bar Bending Schedule (BBS) as the basis for reinforcement quantity analysis. Subsequently, the cutting optimization process was carried out using two software applications, namely Cutting Optimization Pro and Excel Solver, considering control variables such as bar length, diameter, cutting requirements, and installation type. The results show that the conventional method produced a total reinforcement volume of 182,912.41 kg, while the BIM-based method yielded 181,682.58 kg, with only a 0.67% difference from the contract volume. Furthermore, optimization using COP resulted in a total waste of 6.52%, whereas Excel Solver produced 6.74%. The COP method generated a lower waste cost, with a 5.43% difference compared to Solver.
