Time Analysis of the Karangnongko Dam Construction Package 2 in Bojonegoro and Blora Regencies

Abstract

As part of a strategic infrastructure development effort, the construction of the Karangnongko Dam is not only intended to strengthen food security but also expected to increase investment and economic growth in the Bojonegoro and Blora regencies. During its construction period, the project encountered various technical and administrative challenges that led to delays in project completion. Therefore, this study aims to analyze the time required to effectively complete the entire construction work. To determine the most effective and efficient relationship between project cost and duration, this study use the Time Cost Trade-Off (TCTO) method. The analysis focuses on primary activities located on the critical path, as these activities have a significant impact on the overall project completion time. Acceleration strategies are simulated through two simulation: increasing the number of heavy equipment units with a two-shift working system, and increasing the number of heavy with an additional four hours of overtime. The two simulated scenarios proved to be effective in reducing project completion time compared to execution without acceleration strategies. The results of this analysis can serve as a technical basis for stakeholders in formulating decisions to control delays during the construction phase.
