Abstract
<jats:p>On September 28, 2018, an earthquake shook Palu-Sigi-Donggala (Pasigala), resulting in the destruction of several buildings. Another disaster that came at that time was like liquefaction. Liquefaction itself is a process in which non-cohesive materials from solid properties turn into liquid properties due to increased air pressure and pore water in the soil. In the rice field area, liquefaction occurs, so this study aims to determine the potential for liquefaction in the rice field area and to find out how the infiltration of soil after the earthquake is caused by changes in soil characteristics after the earthquake. For this study, the researcher used a liquefaction potential analysis method based on soil grains and liquefaction safety factors and for hydraulic conductivity using the horton method. From the results of field and laboratory research that has been carried out, the results of this study show that in Petobo and Jono-Oge villages, Sibowo and Sidondo villages and Sidera villages have the lowest change in conductivity values so that in laboratory tests it was found that in the area of the two villages there is a type of clay soil and when the liquefaction potential in the village is analyzed it is stated that there is no liquefaction potential due to the soil density in the village Included in the dense category. Then in the village of Pandere-West Sibalaya and Maranata village has a high hydraulic conductivity value and when laboratory testing is carried out it is identified that the soil type of the two villages is sandy soil, then when the liquefaction potential analysis is carried out the two soils have the potential for liquefaction and the density of the soil is not solid..</jats:p>
