Abstract

STRONG SHEAR VALUE OF CLAY SOIL BAYAT KLATEN STABILIZED WITH LIME AND COCONUT SHELL CHARCOAL POWDER ABSTRACT Based on Desanta (2017) research, the physical properties of soil in the Bayat. w = 75%, Gs = 2.638, LL = 63.90%, PL = 30.76%, SL = 12.38%, PI = 33.14%. And for the distribution of soil grains obtained, pass No. sieve. 200 = 75%. Land in the Bayat area is notoriously unfavorable and is easily damaged and many potholes, cracks, bumps and collapsed and according to AASHTO belong to the A-7-5 and USCS groups in the CH group. In this final project will use bayat soil as a sample and stabilization materials are charcoal and lime with a percentage of 0%, 2.5%, 5%, 7.5%, 10% and 5% lime. Physical properties test of charcoal mixed soil including water content, specific gravity, atterberg boundaries from the original soil test obtained atterberg boundaries with LL values 64.00%, PL 24.13%, PI 39.87% and SL 20, 82%. This shows that the land of Beluk Village, Bayat District, Klaten Regency is clay soil with high plasticity and has cohesive properties. According to the ASSHTO method included in group A-7-6 including bad and bad clay soil, according to the USCS method included in the CH group that is non-organic clay soil with high plasticity. The DST test shows the percentage addition of 0%, 2.5%, 5%, 7.5%, and 10% charcoal and 5% lime that the value of cohesion and internal friction angle tends to increase. The largest cohesion value is 1,236 kg / cm2 and the largest friction angle value is 21.10 °. Normal voltage values are 4.47 kg / cm2 and shear stress tends to increase. The biggest shear stress value is 2.957 kg / cm2 in soil with 10% charcoal mixture and 5% lime and the smallest shear stress value is 1.848 kg / cm2 in the original soil. Keywords: Charcoal, Lime, Shear Strength, Physical Properties, Stabilization, Clay Soil.
