Soil of Sukodono is clay has value of LL 85,73%, PL 24,69%, and PI 61,04% (Prasetyo, 2016). The main problem of soil in Sukodono district is when dry season is very hard and in rainy season is very tarnish which is easy to damage condition and easy to crack with building on it. According to Karaseran (2015) with using shell charcoal can improve circulation water and air in soil, as media which increased carbon, and can decrease the shrinkage and swelling on soil because it reduces induction of plasticity of soil. Based on the research above, wood charcoal is used for stabilization material in this research with mixture of 5% and 7,5% with treatment 0, 3, and 7, where the day to know effect of soil with physical characteristic and mechanical soil. Test of physical mixture soil with content and plastic limit increased whereas density, liquidity limit, shrinkage limit, plasticity index, and passing sieve of No. 200 decreasing. Based on AASHTO method, the original soil includes group of A-7-5 and soil mixture includes group of A-7-6 whereas based on USCS the original soil and soil mixture including CH, it is organic clay with high plasticity. Standard Proctor with adding percentage of mixture and the length of treatment value of weight in maximum dry condition decreasing whereas the optimum water content increasing. Volume weight value the smallest maximum dry and the biggest optimum water content of soil percentage with 7,5% with treatment 7 days as big 1,213 gr/cm3 and 33,10%. Whereas volume weight value of the biggest on the original soil with 1,265 gr/cm3. CBR result test showed increasing with adding mixture percentage and the long treatment. The biggest value of CBR on soil mixture of 7,5% with treatment of 7 days of 27% whereas the smallest CBR of 12% on soil mixture of 5% with treatment 0 day.
