Abstract

Soil that has low bearing capacity has a bad impact on the construction that is built on it as a result of which the building is easily damaged such as lifting the foundation on the building and causing cracks and shifting on the road. Therefore, it is necessary to improve the soil. Soil improvement can be done through chemical stabilization. Stabilization can use added materials such as fiber and charcoal ash. In this research, using corncob ash, palm fiber and sodium silicate. The purpose of this study was to determine the bearing capacity of the soil by mixing palm fiber, corncob ash and sodium silicate. This research uses experimental laboratory methods. Soil samples used were taken from Lembang Tondon Siba^ta, Tondon District. Corn cobs were taken from Sa^dan Marante, Sodium silicate is obtained from chemical figures and palm fiber taken from Buntu Tagari and then tested for soil physical characteristics and soil bearing capacity in soil samples with a mixture of sodium silicate, corncob ash, palm fiber and soil without mixture. know the bearing capacity of the soil. The results of the research on stabilized soil by adding 0.2% palm fiber, 2% corncob ash and 3% sodium silicate obtained an increase in soil bearing capacity of 9.73% from the original soil and the addition of 0.2% palm fiber, 4% corncob ash and 3% sodium silicate. experienced an increase in soil bearing capacity of 19.91% from the original land. The addition of 0.2% palm fiber, 6% corncob ash and 3% sodium silicate increased the carrying capacity of the soil by 22.30% from the original soil The resulting mixing results were analyzed to determine the bearing capacity of the soil. The results of the research on stabilized soil by adding 0.2% palm fiber, 2% corncob ash and 3% sodium silicate obtained an increase in soil bearing capacity of 9.73% from the original soil and the addition of 0.2% palm fiber, 4% corncob ash and 3% sodium silicate. experienced an increase in soil bearing capacity of 19.91%
