Abstract

Waterlogging that occurs continuously and the groundwater level rises can cause iron reduction which has an impact on the binding of phosphorus in the soil so that phosphorus is not available for plant growth. The purpose of this study is to test the underground drainage system using rice husks, to reduce the groundwater level and to determine the optimal number and spacing of drainage pipes for use on a macro scale. The research method used is an experimental method on an area of 2x1 meters by observing the time it takes for rice husks to lower the groundwater level, and calculating the water discharge that is not accommodated by rice husks and soil. The results obtained indicate that the average water discharge in Alluvial soils is 2.2 liters/second and in Ultisols 2.5 liters/second. The difference in the value of the sample point is influenced by the different sampling points from where the water exits from the of underground drainage. With sampling points, there are differences in texture, structure, and total pore space which results in differences in the permeability of each sample point. The trial of the of underground drainage in alluvial soil in the first to third trials, the time required to lower the groundwater level is getting faster. Ultisols require less time to lower the water table than alluvial soils because of the larger total pore space compared to alluvial soils and the soil permeability test in the laboratory showed that ultisols were faster than alluvial soils. So, the trial of the of underground drainage using rice husks can be categorized as a successful trial. Keywords : Sub Surface Drainage, Rice Husk, Ultisol Soil, Alluvial Soil
