Abstract

Industri konstruksi minyak dan gas bumi memiliki tingkat bahaya tinggi karena melibatkan pekerjaan multidisiplin, sistem proses kompleks, penggunaan alat berat, serta kondisi lapangan yang dinamis. Penelitian ini bertujuan mengembangkan Construction Project Hazard Index (CPHI), yaitu model penilaian bahaya berbasis linguistik yang mengonversi penilaian subjektif menjadi indeks kuantitatif untuk mendukung pengambilan keputusan keselamatan proyek. Model CPHI dikembangkan dari model eksisting enam komponen menjadi delapan komponen dan 24 atribut bahaya. Pengolahan data mengintegrasikan Trapezoidal Fuzzy Number (TFN), Fuzzy Risk Index (FRI), Analytical Hierarchy Process (AHP), dan Choquet Fuzzy Integral dalam kerangka Multi-Criteria Decision Making (MCDM). Data diperoleh secara purposive dari 17 responden pembobotan AHP, tiga ahli penilai severity dan frequency pada Proyek EPF X, serta 17 validator yang mewakili fungsi manajerial, teknis, HSE, dan pengawasan lapangan. Model diuji melalui expert judgment dan analisis sensitivitas. Hasil penelitian menunjukkan nilai CPHI sebesar 0,5373 yang termasuk kategori bahaya tinggi. Komponen paling dominan adalah Process and System Complexity sebesar 0,6390, diikuti Construction Method and Sequence sebesar 0,5537 dan Human Resource Competency sebesar 0,5477. Atribut berisiko tertinggi adalah metode pelaksanaan konstruksi dan ketidaksesuaian prosedur kerja, dengan FRI sebesar 0,7144. Validasi ahli menghasilkan nilai 4,70 dari skala 5,00 atau sangat valid. Perubahan bobot global ±10% tidak mengubah kategori bahaya maupun komponen dominan. Namun, penurunan bobot Process and System Complexity sebesar 14,6% menurunkan CPHI hingga batas kategori sedang. Dengan demikian, model CPHI dinilai valid dan stabil untuk mengidentifikasi bahaya dominan, menetapkan prioritas pengendalian, dan mendukung keputusan keselamatan proyek konstruksi migas.

The oil and gas construction industry involves a high level of hazard due to multidisciplinary activities, complex process systems, heavy equipment operations, and dynamic site conditions. This study aims to develop the Construction Project Hazard Index (CPHI), a linguistic-based hazard assessment model that converts subjective judgments into a quantitative index to support project safety decision-making. The CPHI model was expanded from an existing six-component model into eight components comprising 24 hazard attributes. Data processing integrated Trapezoidal Fuzzy Numbers (TFN), the Fuzzy Risk Index (FRI), the Analytical Hierarchy Process (AHP), and the Choquet Fuzzy Integral within a Multi-Criteria Decision-Making (MCDM) framework. Data were purposively collected from 17 respondents for AHP weighting, three experts who assessed severity and frequency in the EPF X Project case study, and 17 validators representing managerial, technical, HSE, and field supervision functions. The model was evaluated through expert judgment and sensitivity analysis. The results indicate a CPHI value of 0.5373, classified as a high-hazard category. The most dominant component was Process and System Complexity at 0.6390, followed by Construction Method and Sequence at 0.5537 and Human Resource Competency at 0.5477. The highest-risk attributes were construction execution methods and non-compliance with work procedures, with an FRI of 0.7144. Expert validation yielded a score of 4.70 out of 5.00, indicating that the model was highly valid. A ±10% change in global weights did not alter the hazard category or dominant component. However, a 14.6% reduction in the weight of Process and System Complexity lowered the CPHI to the threshold of the moderate-hazard category. Therefore, the CPHI model is considered valid and stable for identifying dominant hazards, prioritizing control measures, and supporting safety decisions in oil and gas construction projects.
