Abstract

Pekerjaan Horizontal Directional Drilling (HDD) pada konstruksi pipanisasi BBM memiliki risiko K3 yang kompleks karena melibatkan pekerjaan bawah permukaan, penggunaan rig HDD, pekerjaan galian, utilitas eksisting, pengelolaan drilling fluid, serta proses pullback pipa. Penelitian ini bertujuan untuk mengidentifikasi aktivitas kerja, potensi bahaya, dan zona kerja pada pekerjaan HDD-X, menilai tingkat risiko menggunakan metode HIRADC, menganalisis penyebab dominan risiko kritis dengan Fault Tree Analysis (FTA), serta menyusun pengendalian risiko berdasarkan prinsip ALARP, residual risk, Bow Tie Analysis, dan visualisasi ArcGIS. Penelitian ini menggunakan pendekatan deskriptif analitis pada satu studi kasus pekerjaan HDD-X. Data diperoleh dari dokumen proyek, dokumen teknis, layout pekerjaan, serta kuesioner penilaian risiko kepada 14 responden yang memahami pekerjaan HDD, K3, atau pelaksanaan proyek. Pekerjaan HDD-X dikelompokkan ke dalam 10 workflow utama dan 65 sequence pekerjaan utama. Penilaian risiko dilakukan melalui 76 aktivitas kuesioner yang dipetakan ke dalam 110 sequence HIRADC akhir. Pada tahap ALARP dan residual risk, sequence tersebut dirinci menjadi 550 baris detail analisis berdasarkan lima kategori potensi bahaya. Hasil penelitian menunjukkan bahwa risiko awal pekerjaan HDD-X terdiri atas 395 baris risiko Tinggi atau 71,82% dan 155 baris risiko Ekstrem atau 28,18%. Risiko dominan yang diperoleh meliputi kegagalan perizinan dan interface eksternal, ketidaksiapan manpower dan komunikasi kerja, review engineering yang belum memadai, Utility Strike, ketidaksiapan area kerja, kegagalan pengendalian drilling fluid dan slurry, serta Pullback Failure. Dua risiko kritis yang dianalisis menggunakan FTA adalah Utility Strike dan Pullback Failure. Setelah pengendalian diterapkan, residual risk berubah menjadi 10 baris risiko Rendah, 399 baris risiko Sedang, 141 baris risiko Tinggi, dan tidak terdapat risiko Ekstrem. Hasil ini menunjukkan bahwa integrasi HIRADC, FTA, Bow Tie, ALARP, residual risk, dan ArcGIS dapat membantu menurunkan tingkat risiko serta memperjelas lokasi prioritas pengendalian pada pekerjaan HDD-X

Horizontal Directional Drilling (HDD) work in fuel pipeline construction has complex Occupational Health and Safety risks because it involves subsurface activities, HDD rig operation, excavation work, existing utilities, drilling fluid management, and pipe pullback operations. This final project aims to identify work activities, hazards, and work zones in HDD-X, assess the risk level using the HIRADC method, analyze the dominant causes of critical risks using Fault Tree Analysis (FTA), and develop risk controls based on the ALARP principle, residual risk, Bow Tie Analysis, and ArcGIS visualization. This research applies a descriptive analytical approach to a single case study of HDD-X work. The data were obtained from project documents, technical documents, work layout, and risk assessment questionnaires completed by 14 respondents who understand HDD work, occupational safety, or project execution. The HDD-X work was classified into 10 main workflows and 65 main work sequences. Risk assessment was conducted through 76 questionnaire activities, which were then mapped into 110 final HIRADC sequences. In the ALARP and residual risk assessment stage, these sequences were detailed into 550 analysis rows based on five hazard categories. The results show that the initial risk of HDD-X work consisted of 395 High-risk rows or 71.82% and 155 Extreme-risk rows or 28.18%. The dominant risks identified include failure of permitting and external interface control, inadequate manpower readiness and work communication, insufficient engineering review, Utility Strike, inadequate work area readiness, failure of drilling fluid and slurry control, and Pullback Failure. Two critical risks were further analyzed using FTA, namely Utility Strike and Pullback Failure. After risk controls were applied, the residual risk changed into 10 Low-risk rows, 399 Medium-risk rows, 141 High-risk rows, and no Extreme-risk rows. These results indicate that the integration of HIRADC, FTA, Bow Tie, ALARP, residual risk, and ArcGIS can help reduce the risk level and clarify priority control locations in HDD-X work
