IDENTIFIKASI WASTE PROYEK KONSTRUKSI GEDUNG MENGGUNAKAN METODE BORDA DAN METODE ROOT CAUSE ANALYSIS (RCA)

Introduction

Identifikasi waste proyek konstruksi gedung menggunakan metode borda dan metode root cause analysis (rca). Identifikasi waste proyek konstruksi gedung menggunakan metode Borda dan Root Cause Analysis (RCA). Temukan jenis pemborosan dominan dan solusi efektif untuk meningkatkan efisiensi proyek.

Abstract

Proyek konstruksi sering menghadapi kendala yang disebabkan oleh aktivitas yang tidak memberikan nilai tambah atau dikenal sebagai pemborosan (waste). Penelitian ini bertujuan untuk mengidentifikasi jenis pemborosan, penyebabnya hingga merumuskan solusi pada proyek Rumah Sakit Umum Mulia Medika Ramadhan Tegal dan DP Mall Expansion Semarang. Identifikasi waste pada kedua proyek konstruksi gedung ini menggunakan metode Borda dan metode Root Cause Analysis. Pengambilan data dilakukan melalui pengisian kuesioner, wawancara, observasi lapangan, dan dokumen proyek. Dari identifikasi waste, didapatkan bahwa pada proyek Rumah Sakit Mulia Medika Ramadhan Tegal waste yang paling dominan adalah overprocessing 200 poin, waiting 165 poin dan motion 163 poin. Sedangkan pada proyek DP Mall Expansion Semarang waste paling dominan adalah waiting 226 poin, defect 215 poin dan overprocessing 192 poin. Serta didapatkan beberapa solusi yaitu, memberikan arahan SOP sebelum bekerja, meningkatkan pengawasan, mengatur jadwal dan tata letak material dengan baik, serta mendorong keterlibatan semua pihak. Penelitian ini diharapkan dapat membantu proyek sejenis dalam mengenali pola pemborosan dan menentukan langkah perbaikan secara lebih tepat dan efisien.

Review

This paper tackles the critical issue of waste identification and mitigation within the construction industry, an area of significant concern given its impact on project cost, time, and quality. The study's objective to identify waste types, their root causes, and propose solutions across two distinct building projects using the Borda method for prioritization and Root Cause Analysis (RCA) is well-defined and highly relevant. By employing a mixed-method approach involving questionnaires, interviews, observations, and document analysis, the research sets a solid foundation for a practical investigation into construction inefficiencies. A key strength of this research lies in its dual-methodological application, effectively combining a quantitative method (Borda) for ranking waste types with a qualitative analytical tool (RCA) for uncovering underlying causes. The abstract clearly presents project-specific findings, identifying dominant wastes such as overprocessing, waiting, and motion in the hospital project, and waiting, defect, and overprocessing in the mall expansion. The proposed solutions—ranging from SOP implementation and enhanced supervision to improved material logistics and stakeholder engagement—are practical and directly address the identified inefficiencies, offering valuable actionable insights for practitioners and project managers. While the abstract outlines a commendable effort, a more comprehensive review would typically seek further details on certain aspects. It would be beneficial for the full paper to elaborate on whether the inherent differences between a healthcare facility and a commercial mall project significantly influenced the observed variations in dominant waste types, or how these differences were accounted for in the analysis. Furthermore, while the proposed solutions are logical, their generic description suggests a need for more detailed, project-specific implementation strategies within the full manuscript. Lastly, a deeper dive into the specific criteria and scoring mechanisms of the Borda method, as well as the particular techniques applied within the Root Cause Analysis, would enhance the methodological transparency and replicability of the study.
