Soil Permeability Zonation in Rabak Village and Surroundings, Rumpin District, Bogor Regency, West Java

Permeability is the ability of fluids to flow in the soil either through cavities with macro or micro sizes in horizontal and vertical directions. Soil is the result of weathering of a rock where the soil consists of a collection of solid particles with interconnected cavities. It is because of these voids that water can flow in the particles through the voids from one point to another in the direction of lower elevation. The property possessed by the soil is what allows fluids to pass through which is called soil permeability. The purpose of this study was to identify the permeability value of the soil in Rabak Village and its surroundings, Rumpin District, Bogor Regency, West Java. This study uses the constant head permeability method which was carried out at the Geological Engineering Laboratory, Trisakti University, Jakarta. The results of the permeability measurement will be related to the classification of soil type parameters (Department of Soil Science, USU, 2003). Permeability testing using the Constant Head Permeability method used 8 soil samples with the results of 5 samples classified as very fast (>25.4 cm/hour), 2 samples classified as fast (12.7 – 25.3 cm/hour), and 1 sample classified as medium (6.3-12.6 cm/hour) . Based on the results of these measurements can be made a permeability map in the research area.
