Abstract
Masalah waste material merupakan isu besar dalam dunia konstruksi. Berdasarkan
penelitian Lean Construction Institute, tingkat waste di proyek konstruksi jauh lebih tinggi
dibanding manufaktur. Waste material struktur bahkan mencapai 6–15%, tertinggi dibanding
jenis lainnya. Kondisi ini merugikan profitabilitas kontraktor dan berdampak pada lingkungan
sekitar proyek. Waste patrol hadir sebagai metode untuk meminimalisir waste material dan
mengoptimalkan sisa material akibat overproduction. Metode ini tidak hanya diterapkan pada
pekerjaan struktur, namun juga arsitektur dan MEP. Meski proyek konstruksi umumnya telah
merencanakan potensi waste, tidak semua pekerja memahami target yang diharapkan. Oleh
karena itu, waste patrol dapat dijadikan tindak lanjut dari perencanaan waste agar hasil lebih
optimal. Penelitian ini bertujuan untuk menganalisis dampak waste patrol terhadap biaya,
waktu, dan lingkungan proyek. Hasil menunjukkan bahwa penerapan metode ini mampu
mempercepat durasi pekerjaan hingga 5 hari dan menurunkan biaya pelaksanaan sebesar
3,27%, seiring turunnya volume waste material di lapangan. Kuisioner juga menunjukkan
bahwa mayoritas pekerja merasakan manfaat metode ini terhadap pengurangan waste dan
dampak positif bagi lingkungan. Dengan demikian, waste patrol terbukti efektif dari segi
waktu, biaya, dan kondisi lingkungan kerja proyek.
============================================================
Material waste is a major issue in the construction industry. According to research by
the Lean Construction Institute, waste levels in construction projects are significantly higher
than in manufacturing. Structural material waste can reach 6–15%, the highest among all
types. This condition harms contractor profitability and affects the surrounding environment.
Waste patrol is a method that helps minimize material waste and optimize leftover materials
caused by overproduction. This method can be applied not only to structural works but also to
architectural and MEP works. Although most construction projects plan for potential waste,
not all workers understand the expected targets. Therefore, waste patrol can serve as a follow
up action to planned waste management for more optimal results. This study aims to analyze
the impact of waste patrol on project costs, duration, and environmental conditions. The results
show that its implementation can shorten project duration by 5 days and reduce implementation
costs by 3.27%, along with a decrease in on-site material waste volume. Survey responses also
indicate that most workers find the method helpful in reducing waste and providing a positive
environmental impact. Thus, waste patrol proves effective in improving time efficiency, cost
savings, and environmental conditions in structural construction projects.
