ABSTRACT
The effectiveness analysis of slope reinforcement design is essential to ensure stability and safety in landslide-prone areas, such as Jugo Village, Mojo Subdistrict, Kediri Regency. This region has steep topography and saturated soils due to high rainfall, increasing landslide risks that threaten infrastructure and community safety. To address these issues, appropriate slope reinforcement methods were implemented based on the site’s geotechnical characteristics and field conditions. The analysis aimed to assess how well each method could improve slope stability while remaining efficient and cost-effective. Soil investigation data, including laboratory test results and slope geometry measurements, were used in the study. Existing conditions were analysed using Slope/W software with the Bishop method to evaluate slope safety levels in each segment. Two reinforcement alternatives—Mechanically Stabilised Earth Wall (MSE Wall) and soil nailing—were selected based on their suitability. Of the two, soil nailing was found to be more effective due to its higher safety factor values and greater cost-efficiency in material usage. Overall, the study demonstrated that soil nailing provided a better solution for improving slope stability in the area, making it the preferred method for mitigating landslide risks at the study site.
