Pengaruh Kelas Kemiringan Lereng dan Penggunaan Lahan terhadap Sifat Fisik Tanah di Kawasan Penyangga Waduk Cirata Kecamatan Cipeundeuy Kabupaten Bandung Barat
Abstrak
Waduk Cirata is one of impormant water reservoir in West Java. This reservoir was used for
supporting power plants for Java and Bali’s area. It’s need more attention to keep the function
continuity of Waduk Cirata. Greenbelt area was one of factor determinant for establishment of
Waduk Cirata. Landuse change in greenbelt area is a great threat for greenbelt area sustainability,
future more to establishment of Waduk Cirata. This research was aimed to study the effect of landuse
and slope combination to physical property of soil. The research was conducted in greenbelt area of
Waduk Cirata, located in Margalaksana and Nenggeleng Village, Cipeundeuy District, Bandung
Barat. The independent variable was three landuse type and two class of slope, so that were six
combination variable that repeated four times, so there was 24 land unit. This land unit determined
with overlay tools in ArcGIs software. Statistical analysis used for determined the effect and
relationship between parameter. Based on analysis data, combination of landuse type and class of
slope not influence bulk density, porosity, and permeability value. Rubber plantation with class of
slope 8-15% has higher bulk density (1.24 g/cm3) and higher porosity (66.7 %), meanwhile, the
higher of permeability (9.31cm/hour) found in cocoa plantation with class of slope 16-25%.
Keywords: greenbelt area, landuse, class of slope, bulk density, porosity, permeability.
