Abstract

This research was conducted in Kreo Sub-watershed in Semarang and aimed to
examine the difference of soil physical characteristic in various land utilization
typical and to examine the relationship among soil physical characteristic, soil
cover and trees stand conditions to infiltration capacity. In this research, the
picking out of the soil specimens and the test of infiltration was conducted in 10
(ten) kinds of land utilization in the same condition of slope, soil, land use, and
distribution of precipitation. The result of this research showed that there is a
significant difference among the condition of the texture, the porosity, and the
permeability, whereas the organic matter and the early capacity of water have no
significant difference. Whereas adequate correlation was found among the
permeability, the early capacity of water and the soil cover condition, mean while
the trees stand condition, the texture, the organic matter, and the porosity have no
strong correlation with infiltration capacity.
