Analysis of Risk Factors for Delays in the Implementation of the Meninting Dam Construction Project, West Lombok Regency

Abstract

The Meninting Dam Construction Project is part of the National Strategic Project (PSN). Delays can occur in any project, including the construction of the Meninting Dam in West Lombok. This study aims to identify and analyze risk factors impacting the project, determine the risks classified as dominant major risks, and evaluate the residual risks of the Meninting Dam construction project to formulate risk responses that minimize the impact on the project. The study employs the Fault Tree Analysis (FTA) and Probability Impact Matrix (PIM) methods and uses related sources as theoretical foundations. Based on the study results, the Meninting Dam project identified four factors that most significantly affect delays using the FTA method: 1) “Delay in decision-making by the owner,” probability = 17.443%, 2) “Lack of control over work by Construction Management,” probability = 13.771%, 3) “Inadequate planning and control by the Contractor,” probability = 17.207%, and 4) “Weather intensity or high rainfall/heat,” probability = 13.041%. From the identification, four dominant risk variables with high risk levels were obtained using the PIM method: 1) Objections from local residents regarding land acquisition, 2) Delays in material arrival, 3) Delays in procurement of work equipment, and 4) High rainfall causing uncompact soil to become landslides. The risk mitigation category used in this study is risk reduction. The assessment of residual risk shows that of the four risks initially at a high level, these risks decreased after risk mitigation, with two risks becoming moderate and two risks becoming low.
