Soft clay is soil that need microscopic to sub microscopic size originating from the chemical weathering of rock compilers. Clay soil is very hard in a dry state and is plastic at moderate water content. At higher water contents the clay soil is sticky (cohesive) and very soft. Soil stabilization is an effort to improve the quality of the soil by using certain materials to increase soil strength. Soil stabilization is the process of mixing soil with certain materials to improve the technical properties of the soil and is an attempt to change or improve the technical properties of the soil to meet certain technical requirements of the soil carrying capacity. This research is an experimental study to determine the carrying capacity of clay soil stability using volcanic ash deposits and tailings instead of cement. The research variables are volcanic ash deposits which is locked of 8% and tailings with the variation of 4%, 5%, 6% and ripening for 3 days, 7 days and 14 days. The benefits of this experimental study are expected to get the carrying capacity of the soil from stabilized soil greater than the carrying capacity of the original soil by the unconfined compression test (UCS).
