Abstrak
Waste material konstruksi dapat memberikan dampak besar pada proyek pembangunan gedung, terutama pada inefisiensi anggaran proyek dan penurunan kinerja proyek. Faktor penyebab timbulnya waste adalah kurangnya optimalisasi dalam pemakaian besi tulangan karena perencanaan volume dan pola pemotongan yang kurang tepat. Artikel ini mengambil studi kasus pada proyek pembangunan Waron Hospital Women & Children’s Specialist Surabaya. Tujuan artikel ini untuk mengoptimalkan pola potongan besi menggunakan metode Software Cutting Optimization Pro (SCOP) guna mendapatkan pola potongan besi paling optimal untuk mengurangi waste material. Data yang digunakan berupa shop drawing dan bill of quantity. Pemodelan berbasis Building Information Modelling (BIM) menggunakan Software Revit untuk visualisasi 3D, dengan output yang tercapai berupa Quantity Take Off (QTO). Dilanjut dengan menganalisis data QTO menggunakan SCOP untuk menghasilkan pola potongan besi paling optimal. Hasil dari penelitian Berdasarkan hasil analisis waste material besi pada pekerjaan struktur balok plat, dan kolom didapatkan waste terkecil pada pekerjaan kolom sebesar 0,15%, dilanjut dengan pekerjaan plat sebesar 0,22%, dan yang tertinggi pada pekerjaan balok sebesar 0,34%. Hasil optimasi pola potongan ini dapat menghemat biaya sebesar Rp15.426.435,96.

Abstract
Construction waste can have a significant impact on building construction projects, particularly in terms of project budget inefficiency and reduced project performance. The cause of waste is the lack of optimization in the use of reinforcing steel due to improper planning of volume and cutting patterns. This article takes a case study of the Waron Hospital Women & Children’s Specialist Surabaya construction project. The objective of this article is to optimize steel cutting patterns using the Software Cutting Optimization Pro (SCOP) method to achieve the most optimal steel cutting patterns and reduce waste material. The data used includes shop drawings and bills of quantity. Building Information Modeling (BIM)-based modeling was conducted using Revit software for 3D visualization, with the output being a Quantity Take Off (QTO). The QTO data was then analyzed using SCOP to generate the most optimal steel cutting patterns The results of this article show that the lowest waste was found in column work at 0.15%, followed by plate work at 0.22%, while the highest waste was in beam work at 0.34%. This optimization of steel cutting patterns can save costs amounting to Rp15.426.435,96.
