Abstract

Road maintenance is a strategic effort to support community mobility and economic development. This study aims to determine the optimal duration and analyze the cost impacts of implementing the Time Cost Trade Off (TCTO) method. The method is applied through critical path analysis and adding overtime hours to reduce the project duration. Data is collected from project documents such as daily reports, S-curves, and cost budget plans, then analyzed using Microsoft Project software. The results show that the project duration can be shortened to 117 days with an additional cost of IDR 176,614,724.00, which is lower than the potential delay penalty of 1% per day. This adjustment leads to a time savings of 8.6% without causing significant changes to the project's organizational structure. The TCTO method proves to be a practical solution for addressing delays while maintaining a balance between time and cost.

Abstract

Prolonged road damage disrupts community mobility, logistics activities, and reduces road user safety. The road maintenance project on Jl. Ir. Soekarno in Blitar City, which was planned to be completed in 120 days with a budget of Rp1.16 billion, experienced a delay of 8 days due to time management constraints. This study aims to evaluate the use of the Time Cost Trade Off (TCTO) method to accelerate project completion without reducing the quality of work. The TCTO method is used to analyze the relationship between time and cost. This research proposes additional overtime working hours of 2 hours per day with the assumption of resources according to the Cost Budget Plan (RAB). The results show that with this method, the project can be completed in 117 days at a total cost of Rp1,342,177,724. Although it requires additional costs, this acceleration allows the project to be completed faster than the previous condition
