Abstract

Soil is geological material that is in the earth's crust that is used as a working medium or to build buildings on it. Construction on peatlands has the potential to be damaged because the carrying capacity of peat is very low and has high water content, resulting in a very large subsidence. Efforts to be made are chemical stabilization using coal waste from combustion, namely bottom ash. This study used peat soil samples taken from Tanjung Palas, Dumai City. Then the peat soil samples were tested for their physical and mechanical properties in the geotechnical laboratory. There have been many studies using chemicals as peat soil stabilizers, but the use of bottom ash for peat soil in Dumai City has never been done. From the results of this study, it turns out that bottom ash can increase the bearing capacity of peat up to 2.4% in a mixture of 40% bottom ash 60% peat.
