Analysis of Physical Properties and Soil Uplift by Searching for Swelling Values in Barbate Quarry Soil for Earthquake Disaster Mitigation Efforts

Abstract

Aceh Besar District is part of the Province which is located on the tip of the island of Sumatra and this area is on the Sumatra Fault fault as well as the local fault. Areas that are on active faults can result in the possibility of an earthquake being quite high, this is because the area is quite close to the epicenter. The purpose of this study was to determine the value of the physical properties and uplift of the quarry soil in the Barbate area of Kurma-Paya Kameng Gardens so that if the PI value of the soil is >17%, the soil needs to be stabilized with coffee husk ash as a mixed ingredient. The research research method was testing soil samples at the Soil Mechanics Laboratory at Syiah Kuala University. The results of the study show that this soil is of the clay type and has a PI value of 38.42% so stabilization is carried out, the soil uplift value also shows that the value is increasing and the highest point of the calculation results is at a 25% mixture of 22.37 kg.
