Kajian Laju Infiltrasi Tanah pada Berbagai Penggunaan Lahan di Desa Tanjung Putus Kecamatan Padang Tualang Kabupaten Langkat

Abstract

SRI PUSPITA SARI : Study of infiltration soil ratein some lands using at Desa Tanjung Putus Kecamatan Padang Tualang Kabupaten Langkat, guide by Sumono and Nazif Ichwan. The aim of this research was to know infiltration rate in some lands using that are field, rubber field, and bush at Desa Tanjung Putus Kecamatan Padang Tualang Kabupaten Langkat using Phiips equation model. Parameter that perceived were moisture content, soil texture, bulk density, particle density, porosity, and organical matter. This research 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. The results showed that the biggest infiltration was found in rubber field, and bush, the smallest was found in field. The biggest influence to infiltration rate are soil texture and porosity.
