Estimation of Road Repair Costs for the Genengan–Lembeyan Section in Magetan Regency Based on the 2024 Bina Marga Guidelines

Abstract

The Genengan–Lembeyan road section in Magetan Regency is a vital transportation route connecting Magetan with Ponorogo, facilitating mobility and goods distribution. However, the road has experienced significant degradation due to increasing traffic and the passage of heavy vehicles, affecting both safety and comfort for users. This research aims to evaluate the pavement condition using the International Roughness Index (IRI) method, with support from the Roadroid application, which provides real-time road condition data. Additionally, the research calculates estimated repair costs based on the Bina Marga 2024 guidelines. The results indicate an average IRI value of 4.24, with some segments in moderate condition, while the STA 5+000 to STA 8+660 section shows critical damage with an IRI value exceeding 6.5. Immediate rehabilitation is necessary for this section to prevent further damage and ensure road safety. The estimated repair cost for this segment is Rp4,069,031,000.00, covering interventions such as overlay, patching, and structural improvements. This research highlights the effectiveness of the Roadroid application as a cost-efficient alternative to traditional survey methods. The findings provide useful insights for local governments to prioritize repairs, allocate resources effectively, and implement timely maintenance strategies, thereby contributing to the sustainability and functionality of road infrastructure and supporting regional economic growth and community well-being.
