Soil is the material on which the structure built.. Soil conditions on the site greatly affect the type of foundation used. Clay is a bad type of soil if it has poor soil properties such as high plasticity, low shear strength, high swelling, and large shrinkage potential. Soil stabilization is an effort to improve the quality of the soil by using certain materials to increase soil strength. Soil improvement by using mixture materials are mostly done to stabilize the soil. The mixing material used is Lapindo mud. A number of soil improvement techniques are offered to overcome problems in soft soil. The selection of soil improvement techniques is generally based on the formation of soil geology, soil characteristics, and costs. The stabilization used is emulsion asphalt which is locked of 8% and Lapindo mud variation of 3%, 6%, 9% and 12%. The results of physical and mechanical properties on soil material with stabilization of Lapindo mud and emulsion asphalt were obtained that the specific gravity increased by about 68%, with the density value of 16% and the dry weight content of 6%. In the compressive strength testing, the more Lapindo mud mixture, the less compressive strength (qu) value.
