Abstract

Penelitian ini bertujuan untuk menganalisis risiko Keselamatan dan Kesehatan Kerja (K3) pada pekerjaan konstruksi core wall di Proyek Menara Komunikasi yang telah mencapai progres 70%. Pekerjaan didominasi oleh vendor maupun subkontraktor lebih dari 80%, yang menghadirkan tantangan koordinasi dan standarisasi K3. Metode yang digunakan meliputi Job Safety Analysis (JSA), Hazard Identification, Risk Assessment, and Determining Control (HIRADC), Analytical Hierarchy Process (AHP), serta Cost-Benefit Analysis (CBA). Data diperoleh melalui observasi, kuesioner, dan wawancara terhadap lima belas responden dari berbagai posisi, mulai dari pekerja lapangan hingga manajer proyek. Hasil penelitian menunjukkan bahwa pekerjaan dengan risiko tertinggi adalah climbing formwork dan reforming roof dengan nilai risiko tinggi. AHP digunakan untuk menetapkan prioritas mitigasi berdasarkan kriteria severity, likelihood, dan cost, di mana severity menjadi faktor dominan. CBA menunjukkan bahwa meskipun biaya mitigasi cukup tinggi, pengendalian tersebut efektif dalam menurunkan eksposur risiko secara signifikan, khususnya pada aktivitas kerja di ketinggian dan penggunaan alat berat. Integrasi keempat metode menghasilkan strategi mitigasi yang objektif, efisien secara biaya, dan relevan untuk diterapkan pada proyek konstruksi berskala besar dan kompleks.

This study aims to analyze Occupational Health and Safety (OHS) risks in the core wall construction work of the Communication Tower Project, which has reached 70% progress. Over 80% of the work is carried out by vendors and subcontractors, presenting challenges in coordination and standardization of OHS practices. The methods employed include Job Safety Analysis (JSA), Hazard Identification, Risk Assessment, and Determining Control (HIRADC), Analytical Hierarchy Process (AHP), and Cost-Benefit Analysis (CBA). Data were collected through field observations, questionnaires, and interviews with fifteen respondents ranging from field workers to project managers. The results show that the highest-risk activities are climbing formwork and reforming roof, both classified as high-risk. AHP was used to prioritize mitigation actions based on three criteria: severity, likelihood, and cost, with severity identified as the most dominant factor. CBA indicated that despite the relatively high mitigation costs, the proposed controls are effective in significantly reducing risk exposure, especially for activities at height and heavy equipment operation. The integration of these four methods provides a mitigation strategy that is data-driven, cost-efficient, and applicable to large-scale and complex construction projects.
