Abstract

Penerapan teknologi Building Information Modeling (BIM) memiliki peran yang krusial dalam meningkatkan efisiensi proyek konstruksi, khususnya dalam hal pengelolaan material seperti besi tulangan, yang berpengaruh besar terhadap biaya dan struktur proyek. Di wilayah seperti Tulungagung, penggunaan BIM dalam proyek konstruksi berskala kecil dan menengah masih terbatas. Oleh karena itu, kegiatan pengabdian masyarakat ini dirancang untuk mengedukasi dan melatih pelaku konstruksi lokal dalam pemanfaatan teknologi BIM, dengan fokus pada perencanaan material tulangan besi. Pelatihan ini memanfaatkan perangkat lunak Autodesk Revit untuk membuat model struktur 3D serta menerapkan metode Bar Bending Schedule (BBS) guna menghitung volume, berat, dan estimasi material dengan lebih presisi. Hasil pelatihan menunjukkan bahwa penerapan BIM dapat menurunkan pemborosan material besi tulangan hingga 18,7% dan mempercepat estimasi waktu pengerjaan dari 9 jam menjadi 3 jam. Peserta pelatihan, mayoritas pelaku konstruksi lokal, menunjukkan antusiasme yang besar untuk mengintegrasikan BIM dalam proyek mereka di masa depan. Temuan ini menegaskan bahwa pelatihan berbasis studi kasus lokal tidak hanya meningkatkan efisiensi dan ketepatan dalam perencanaan, tetapi juga memperkuat kapasitas sumber daya manusia di sektor konstruksi. Oleh karena itu, disarankan untuk memperluas inisiatif serupa di daerah-daerah lain yang memiliki karakteristik serupa serta menyediakan infrastruktur digital yang mendukung guna memperkuat dampak positif dari adopsi BIM dalam industri konstruksi di Indonesia

Abstract

The rapid development of construction technology demands building systems that are efficient in terms of cost, time, and quality. In the context of light infrastructure such as perimeter fencing, the choice of construction method significantly affects the total project cost over its service life. This study aims to compare the economic efficiency of precast concrete panel fences and conventional concrete block (batako) fences using a Life-Cycle Cost (LCC) analysis approach. This research adopts a quantitative–comparative method based on the Life-Cycle Costing Manual (Fuller & Petersen, 1995) and ISO 15686-5:2017 standards. Data were obtained from an actual fencing project in Kediri City, including cost estimates (RAB), material volumes, construction duration, and maintenance costs. The analyzed parameters include Capital Expenditure (CAPEX), Operational Expenditure (OPEX), and Event Costs, using an 8% discount rate and a 20-year project service life. The results show that the precast fence system yields a total Net Present Cost (NPC) of IDR 608.88 million, while the concrete block fence reaches IDR 848.12 million, indicating a cost efficiency of approximately 39%. In addition, the precast system requires only 14 days for installation, which is 58.8% faster than the concrete block system that requires 34 days. In terms of dimensions, the precast fence uses 63.9% less material volume and has a lighter structural weight. Overall, the precast concrete panel fence demonstrates higher cost efficiency, faster construction time, and better material durability under the humid tropical climate of Kediri.

Abstract

High-rise building construction projects involve a high level of hazards and uncertainty, requiring the systematic implementation of occupational safety risk management. This study aims to identify and classify occupational health and safety (OHS/K3) risk levels and to formulate control measures for high-rise building construction projects. The research method employs a quantitative approach through the distribution of questionnaires to 39 respondents, with risk analysis based on the standard AS/NZS 4360:2004 risk matrix. The results indicate that 8% of the variables fall into the high-risk category, 40% into the medium-risk category, and 52% into the low-risk category. High risks are primarily associated with structural work activities and field operations that have the potential to cause serious accidents. The contribution of this study lies in the presentation of measurable and applicable OHS risk mapping, along with risk-level-based control recommendations, which can serve as a practical reference for project managers in improving the effectiveness of OHS management system implementation in sustainable building construction projects.
