Abstract

Pesatnya perkembangan sektor konstruksi di berbagai daerah tercermin dari banyaknya proyek yang dilaksanakan. Namun, dalam prosesnya, sering muncul permasalahan berupa waste material yang dapat merugikan proyek serta membahayakan kelestarian lingkungan jika tidak dikelola dengan baik. Penelitian ini menganalisis waste material dalam Proyek Pembangunan dengan mengidentifikasi jenis waste material yang dominan, menghitung besarnya waste cost, serta menentukan faktor utama penyebabnya. Material dominan ditentukan menggunakan Pareto Principle untuk mengidentifikasi material yang berkontribusi terhadap 80% nilai waste cost, sementara analisis faktor penyebab dilakukan dengan Fishbone Diagram, yang dikembangkan melalui validasi hasil penelitian sebelumnya serta wawancara dengan narasumber terkait. Sehingga, hasil penelitian ini akan memberikan output mengenai jenis material, waste cost, serta faktor-faktor utama yang menyebabkan pemborosan material pada Proyek Tower 3 Institut Teknologi Sepuluh Nopember. Identifikasi faktor penyebab waste material dilakukan dengan merujuk pada penelitian terdahulu, kemudian divalidasi dan dikembangkan melalui wawancara dengan narasumber terkait. Hasil analisis menunjukkan bahwa jenis material yang menghasilkan kuantitas waste terbesar adalah Baja Tulangan Polos (BjTP), Beton Ready Mixed K-500, Beton Ready Mixed K-400, ACP Seven PVDF 4 mm Alloy 5005 0,5 mm, serta Mortar Siap Pakai (Semen Instan). Total waste cost yang timbul dari material-material tersebut mencapai Rp 886.804.496. Waste material tersebut disebabkan oleh
beberapa faktor, antara lain faktor manpower berupa kesalahan pekerja, faktor manajemen yang berkaitan dengan kesalahan pihak manajemen, faktor metode yang meliputi kesalahan dalam penyimpanan material, faktor desain yang dikarenakan oleh desain yang rumit, serta faktor
lingkungan (mother nature) berupa cuaca buruk.

The rapid development of the construction sector in various regions is reflected in the many projects being implemented. However, during the process, problems often arise in the
form of material waste that can harm the project and threaten environmental sustainability if not managed properly. This study analyzes material waste in a construction project by identifying the dominant types of waste materials, calculating the amount of waste costs, and determining the main factors causing them. Dominant materials are identified using the Pareto Principle to pinpoint those contributing to 80% of the total waste cost, while causal factors are analyzed using a Fishbone Diagram developed through validation of previous research results
and interviews with relevant sources. Thus, the results of this study provide information regarding the types of materials, waste costs, and the main factors causing material waste in the Tower 3 Project at the Sepuluh Nopember Institute of Technology. Identification of factors
causing material waste is conducted by referring to previous research, then validated and expanded through interviews with related sources. The analysis results show that the materials producing the largest quantities of waste are Plain Reinforced Steel (BjTP), Ready Mixed Concrete K-500, Ready Mixed Concrete K-400, ACP Seven PVDF 4 mm Alloy 5005 0.5 mm, and Ready-to-Use Mortar (Instant Cement). The total waste cost from these materials reached Rp 886.804.496. The material waste was caused by several factors, including manpower factors such as worker errors, management factors related to management mistakes, method factors including errors in material storage, design factors due to complicated designs, and environmental factors in the form of bad weather.
