The Study of the Rate of Infiltration and Soil Permeability on Different Land Cover in Watershed Maluka Province of South Kalimantan

Abstract

—Infiltration is part of the hydrologic cycle, namely the process of entering water from the surface into the soil. Infiltration is affected by vegetation, slope and soil type. This study aims to analyze the amount of capacity and volume of infiltration in open land, shrubs and rubber plantations in the watershed Maluka. This research method using the formula Horton with point observation using a purposive sampling by observing the various land closure. The results showed that the highest infiltration capacity value on the secondary forest land cover of 5,945 mm/hour and the lowest is the reeds with a value of 0,687 mm/hour. The value of the highest volume of infiltration in the secondary forest of 3,249 mm³ whereas the lowest on the Palm of 0,153 mm³
