Abstract

Landslide management on national road infrastructure requires construction methods that can ensure slope stability while accelerating project completion time, especially on sections with high traffic such as the Niam–Lubuk Kambing intersection STA 17+070. The change in method from borepile retaining walls to geotextiles as a result of budget efficiency policies has created a need for analysis of the duration of implementation. This study aims to compare the implementation times of the two methods in order to obtain a more effective alternative to support project acceleration. The research methods include technical data processing, work item compilation, project scheduling, and progress analysis using the S-Curve. The analysis results show that the bored pile method requires 120 calendar days, while the geotextile method can be completed in 90 calendar days. There is a time acceleration of 30 days or 25% faster in the geotextile method. Based on these results, the geotextile method is considered more efficient in terms of duration and contributes significantly to the optimization of project implementation time for landslide mitigation.

Abstract

Landslides are one of the geotechnical problems that often occur in slopes and soft soil areas, especially on roads with peat soil conditions and high traffic volumes, such as the Simpang Niam–Lubuk Kambing STA 17+070 National Road. Changes in the 2025 budget efficiency policy have resulted in the landslide mitigation method, which was originally planned to use Borepile retaining walls (DPT), being changed to a Geotextile method, thus requiring a comparative study of the cost aspects. This study aims to analyze and compare the cost effectiveness of the bored pile retaining wall and Geotextile methods at the location. The research methods include collecting technical field data, calculating the volume of work, analyzing the unit price of work (AHSP), and preparing a Budget Plan (RAB) for each alternative. The analysis results show that the total cost of work using the DPT Borepile method is IDR 7,808,047,000, while the Geotextile method is IDR 7,151,225,000. There is a cost difference of IDR 656,822,000 or about 8.4% more economical in the Geotextile method. Based on these results, the Geotextile method is considered more economically efficient and contributes to the optimization of budget utilization in landslide management projects on peatlands.
