Cost Control Analysis Using the Critical Path Method in the Construction of Disaster Emergency Response Handling Projects in the Sumber Pasinan River, Mojokerto Regency

Abstract

The landslide on the banks of the Sumber Pasinan River in Mojokerto Regency, East Java, has caused significant damage, including the displacement of river rocks and exacerbated erosion due to frequent flooding during the rainy season. As a Swakelola project, the construction of the river stone pair must be completed efficiently within a minimal timeframe and cost. This study aims to estimate the costs associated with accelerating the construction project using the Critical Path Method (CPM). A quantitative approach was employed, applying project management theories to address practical challenges in the Disaster Emergency Response Handling Project. Based on the results of the acceleration of the working days analyzed using the Critical Path Method (CPM), there was an acceleration of 24 days, which required the addition of 11 workers. The cost of acceleration caused an increase in labor costs (cost slope) of Rp16,486,500.00 compared to the previous cost budget plan. The findings demonstrate the effectiveness of the CPM in optimizing project timelines while highlighting the need for careful cost management. This research provides valuable insights for contractors and project managers, offering strategic recommendations to enhance time and cost efficiency in similar construction projects. The implications of this study extend to improved disaster response planning and resource allocation, ensuring timely and cost-effective project completion.
