Life Cycle Cost Analysis on the Maintenance of Road Reservation Works in Kanasan – Capital of Gunung Tabur Subdistrict, Berau Regency

Abstract

Road infrastructure plays a vital role in connecting regions, supporting public mobility, and driving economic growth across multiple sectors. Well-maintained roads improve accessibility, enhance the efficiency of goods distribution, and accelerate the flow of goods and services. In Berau Regency, the quality of road infrastructure is a crucial factor in supporting community economic activities, particularly in remote areas such as Gunung Tabur. However, road maintenance in these regions often faces significant challenges, including limited budgets, difficult geographical conditions, and extreme weather. These conditions complicate road management and maintenance, requiring efficient cost allocation strategies. In the context of the Kanasan Road in the Capital of Gunung Tabur Subdistrict (IKK), proper maintenance can help extend the lifespan of the road and reduce the need for more costly repairs in the future. This study aims to analyse the total Life Cycle Cost (LCC) of the road reservation maintenance project on Kanasan Road over a 12-year period. The primary focus is to determine the total LCC and the contribution of each cost component, namely the Initial Cost and Maintenance Cost. A quantitative descriptive approach was employed, involving a systematic analysis of road construction and maintenance cost data. The results show that the total LCC of the project is IDR 22,811,802,000, consisting of an Initial Cost of IDR 19,528,342,000 and a Maintenance Cost of IDR 3,283,460,000, adjusted for an annual inflation rate of 3.1%. The Initial Cost accounts for 85.6% of the total LCC, while the Maintenance Cost contributes 14.4%. These findings highlight the importance of incorporating maintenance costs into long-term infrastructure budget planning, even though their proportion is smaller compared to the initial construction cost.
