Kajian Laju Infiltrasi Tanah pada berbagai Penggunaan Lahan di Desa Sempajaya Kecamatan Berastagi Kabupaten Karo

Abstract

RIKA ISNAINI : Study of Soil Infiltration Rate in Some type of Lands at Desa Sempajaya Kecamatan Berastagi Kabupaten Karo, supervised by Sumono and Ainun Rohanah. The aim of this research was to know the infiltration rate in some type of lands in edition chili field, coffee field, and bush at Desa Sempajaya Kecamatan Berastagi Kabupaten Karo using Philips equation model. Parameters observed were moisture content, soil texture, bulk density, particle density, porosity, and organical matter was used. Double ring infiltrometer that pressed into the soil, and filled with water. The decreased of water was observed with interval 0, 5, 10, 20, 30, 45, 60, 120, 180, 240 minutes. The results showed that the highest infiltration rate was found in bush, followed by chili field, and the smallest was found in coffee field. The biggest influence on the infiltration rate were soil texture and porosity.
