Abstract
Sistem counterweight pada proyek konstruksi memiliki potensi bahaya tinggi akibat energi potensial gravitasi yang dapat menyebabkan kecelakaan serius apabila terjadi kegagalan mekanis. Penelitian ini bertujuan menerapkan metode House of Risk for Safety, Health, ETC. (HORshe) untuk mengidentifikasi risk event dan risk agent, menentukan prioritas risiko berdasarkan nilai Aggregate Risk Potential (ARP), serta merumuskan tindakan mitigasi yang sesuai. Data diperoleh melalui observasi lapangan selama 48 jam, wawancara terhadap 12 informan, dan kuesioner expert judgment kepada delapan ahli. Hasil penelitian mengidentifikasi 12 risk event dan 10 risk agent. Interaksi Liveware–Environment (L–E) dan Liveware– Hardware (L–H) merupakan kategori yang paling dominan (33,3%). Nilai ARP tertinggi diperoleh risk agent A3 (pekerja melintas di bawah lintasan counterweight) sebesar 2.940. Enam risk agent prioritas berkontribusi sebesar 86,2% terhadap total nilai ARP. Berdasarkan analisis ETDk, tindakan prioritas adalah eliminasi akses permanen di bawah lintasan counterweight. Evaluasi risiko residual secara simulatif menunjukkan potensi penurunan risiko A3 sebesar 95%. Hasil penelitian menunjukkan bahwa metode HORshe dapat digunakan untuk mendukung penentuan prioritas mitigasi risiko pada sistem counterweight di proyek konstruksi.

Counterweight systems in construction projects pose a high safety risk due to the large amount of gravitational potential energy they store, which may lead to serious accidents in the event of mechanical failure. This study aimed to apply the House of Risk for Safety, Health, ETC. (HORshe) method to identify risk events and risk agents, prioritize risks based on the Aggregate Risk Potential (ARP) value, and develop appropriate mitigation measures. Data were collected through 48 hours of field observation, interviews with 12 informants, and expert judgment questionnaires involving eight experts. The results identified 12 risk events and 10 risk agents. Liveware–Environment (L–E) and Liveware–Hardware (L–H) interactions were the most dominant categories, each accounting for 33.3% of the identified risk events. The highest ARP value was obtained by risk agent A3 (workers passing beneath the counterweight path), with a score of 2,940. The six highest-priority risk agents accounted for 86.2% of the total ARP value. Based on the ETDk analysis, permanent access elimination beneath the counterweight path was identified as the highest-priority preventive action. A simulated residual risk evaluation indicated a potential 95% reduction in the risk associated with A3. The findings indicate that the HORshe method can support risk prioritization and mitigation planning for counterweight systems in construction projects.
