The effect of the land cover plant on infiltration rate in Alas Bromo, Karanganyar

Abstract

Forest management is a way to keep the forest well-preserved. Forest management can mitigate the impacts of climate change. It will affect the balance of the environment such as the balance in the hydrological or water systems aspect. Infiltration is one of the water system factors in hydrology. This research aims to determine the value and classification of the infiltration rate. This research was conducted using a descriptive exploratory method to determine the infiltration rate of each land cover plant. This research is in Alas Bromo, Karanganyar, Central Java which has Alfisol soil types with six land uses: seasonal mixed, annual mixed, mahogany, pine, pine-mahogany, and renewal. Different types of land cover and plant characteristics affect the soil condition and the ability to absorb water into the soil. The calculation of the infiltration rate uses the Philip method. According to the classification of the infiltration rate in Alas Bromo, four classes were obtained including: moderately rapid 9.15 cm.h-1 (Mahogany), moderate 3.72, and 2.77 cm.h-1 (Pine and Pine-Mahogany), moderately slow 0.87 cm.h-1 (annual mixed), slow 0.28 and 0.265 cm.h-1 (seasonal mixed and renewal). Therefore, the presence of land-cover plants increases the infiltration rate.
