Pendugaan Laju Infiltrasi Menggunakan Parameter Sifat Tanah Pada Kawasan Berlereng

Abstract

The infiltration measure in the cycle area is seldom done , because it is difficult to putting the tools and getting the water . It needs a research to forecast the number of infiltration rate in cycle area without have to measure infiltration directly . The aim of this research is to find out infiltration rate model to based on soil properties in hilly forested area by double ring infiltrometer method . The research result showes that the best forecast model is using soil properties that clays fraction , bulk density , porosity and soil organic material to the maximum infiltration rate with determination coefficient 0,567 and the time to get constant with R² 0,760 and the pattern for minimum infiltration rate model is not suistable to use because it only has the low determination coefficient with 0,162 .
