Summary: | Abstract
Liquefaction is an event in which the soil loses shear strength due to increased pore water stress by the presence of cyclic loading. As a result of this incident, a number of paddy fields and housing estates in Jono Oge village experienced liquefaction. There is mud vomiting and the movement of a number of soils, causing eroded areas and some of them experiencing hoarding Research aims to identify the chemical properties of soils affected by liquefaction. The study was conducted using the survey method, soil sampling was carried out by purposive sampling. Soil samples were taken on three categories of affected land: eroded land, landfilled land, and surrounding land that was not liquefied. The results showed that the areas affected by liquefaction in the three categories of land had a soil pH relative to the same criteria, namely neutral (pH 6.52-6.77). Then C-organic levels in both eroded and hoarding fields are moderate status (2.50-2.70%) and in non-liquefied lands is low status (1.52%), while N-Total all three have low status (0.12-0.19%). Sodium content is generally medium status (0.41-0.60 me/100g), Calcium is generally high status (11.88-13.42 me/100g) and Magnesium is generally moderately. This research was conducted after more than 2 years of liquefaction and the most affected soil chemical properties in the respected area is the increasing of C-organic content. |
