Abstract


The practice area for the Banjarbaru State Agricultural Development Vocational School (SMK PP N Banjarbaru) is located in Kemuning Village, South Banjarbaru District, Banjarbaru City, South Kalimantan Province. Regarding the land use in the research location, the majority is used for plantation land, which is one of the lands suitable for water catchment areas in Banjarbaru City. The Practice Land of PPN Banjarbaru Vocational School, is one of the models of good catchment area land from good land use and irrigation systems. This research was conducted to analyze the infiltration rate and its influence on the physical properties of the soil. From the results of the infiltration test using a double ring infiltometer which was then analyzed using the Horton method, the largest infiltration rate was in open land, namely 33.83 cm/hour, rubber plantations of 22.57 cm/hour, then on palawija land it is 15.57 cm/hour and on mahogany land it is 14.47 cm/hour. From the results of the analysis using the linear regression approach, the physical properties of the soil that can affect the infiltration rate include 16.7% bulk density, 75% permeability and 90% moisture content. Meanwhile, particle density and porosity only affect 0.7% and 3.5%.

Keywords: Infiltration, Infiltration Rate, Soil Physical Properties
