Abstract

High-plasticity clay soil commonly exhibits low bearing capacity and therefore requires an effective, economical, and applicable reinforcement method. This study aims to analyze the effect of bamboo pile length variation on the unconfined compressive strength of clay soil from Kedungdandang Hamlet, Tapanrejo Village, Muncar District, Banyuwangi Regency. Disturbed soil samples were collected at a depth of 70 cm and characterized through sieve analysis, water content, specific gravity, unit weight, and Atterberg limit tests. Mechanical performance was evaluated using the Unconfined Compression Test on untreated clay and clay reinforced with bamboo piles measuring 3 mm in diameter, 1.25 cm spacing, and lengths of 3.5, 5, and 7.5 cm. The soil was classified as high-plasticity clay, with a liquid limit of 81.81% and plasticity index of 46.96%. The average UCS increased from 26.60 kPa to 32.66, 36.61, and 47.19 kPa. The 7.5 cm piles provided the highest improvement, 77.41% over untreated soil.

Abstract

Songgon District is one of the areas in Banyuwangi Regency that has a high vulnerability to landslides due to steep slope topography, high rainfall, and tectonic and volcanic activity from Mount Raung. This study aims to analyze slope stability, identify landslide-prone zones, and develop an appropriate disaster mitigation strategy matrix in the area. The research method used is an integrative approach that combines numerical modeling based on the 3D Finite Element Method, and Geographic Information System (GIS)-based spatial mapping with Kriging interpolation techniques. Slope stability analysis was conducted at 15 critical review points spread across the Songgon area. The modeling results show significant variations in slope stability levels, where several critical points show safety factors below the safety limit FK < 1.25. Based on the spatial zoning generated through GIS Kriging, the study area is mapped into three vulnerability zones: low, medium, and high vulnerability zones. As an output of the mapping and analysis of geotechnical parameters, a comprehensive disaster mitigation matrix was prepared, including structural recommendations (such as slope reinforcement and drainage improvements) and non-structural recommendations (such as community-based early warning systems and evacuation route mapping) to minimize the risk of future disaster impacts.
