IDENTIFIKASI RISIKO KONSTRUKSI PADA PEKERJAAN STRUKTUR BAJA WORKSHOP PT. INKA BANYUWANGI DENGAN METODE ANALYTICAL HIERARCHY PROCESS (AHP)

Railway factory PT. Industri Kereta Api (Persero) in Banyuwangi was built by PT. Adhi Karya (Persero) Tbk. as the main contractor. The main construction used in the project is a steel structure (pre-engineered steel building). The work is not free from the emergence of risks, because of the significant weight of the work carried out. Risk cannot be eliminated, but it can be minimised by implementing risk management. One of the risk management processes is risk identification. This research aims to identify the possible risks that can occur, and the category of emergency for the project. Data were collected by distributing questionnaires to four respondents, namely the contractor’s project manager. Furthermore, the data from the questionnaire was processed using the Analytical Hierarchy Process (AHP) method to find the risk weights. The analysis process is continued by assessing the risk level for each sub-risk variable, and the most significant result is considered the dominant risk. The identification resulted in 3 high risks, three medium risks, and 18 low risks. The three most increased risks are as follows: the availability of materials with a weight of 2.581, the transfer of potential senior workers with a weight of 0.989, and changes in the work schedule with a weight of 0.779.
