Analysis of Cost and Time Performance in the Drainage Channel Construction Project of Laju Lor Village, Tuban Regency, using the Earned Value Method

Abstract

The drainage construction project in Laju Lor Village, Tuban Regency, faced significant schedule deviations, with delays occurring at various stages. These deviations were attributed to challenges such as resource allocation issues, coordination inefficiencies, and unforeseen external factors. This research aims to assess the effectiveness of the Earned Value Method (EVM) in managing project performance, particularly in mitigating delays and cost overruns during the construction process. The research employs the Earned Value Method (EVM), which integrates time and cost indicators: Actual Cost of Work Performed (ACWP), Budgeted Cost of Work Performed (BCWP), and Budgeted Cost of Work Schedule (BCWS). Additionally, key performance indices such as the Cost Productivity Index (CPI), Schedule Performance Index (SPI), Estimated Cost at Completion (EAC), and Estimated Time for Completion (ETC) were calculated to evaluate the project's performance. The findings reveal that the project's estimated cost at completion (EAC) was Rp1,040,304,209.89, providing a cost-saving of Rp20,726,358.11 compared to the initial budget of Rp1,061,030,568. However, the project experienced an extended completion time, reaching 81 days, exceeding the original schedule by 21 days. The research demonstrates that the Earned Value Method is an effective tool for identifying project performance issues and guiding corrective actions. The results emphasize the importance of efficient resource management, proactive scheduling adjustments, and stringent supervision to minimize delays and cost overruns. The findings offer valuable recommendations for future infrastructure projects, particularly in rural areas, where similar challenges may arise.
