PEMETAAN DAERAH RESAPAN AIR DI KABUPATEN MAJALENGKA PROVINSI JAWA BARAT DENGAN MENGGUNAKAN GIS
Abstract
Water catchment area is basically not to be explored excessively because
it will have an impact on soil structure that previously fertile and stable then it
will turn into fragments that will not be able to hold water when it rains, so that
the land that was previously categorized fertile into arid land and it’s nutriens
element content is reduced. Potential damage to forests and water catchment
areas in the Majalengka Regency highly increases in line with the medium-long

Catchments in Majalengka. The research has been conducted in Majalengka from

technical implementation of map overlaying and scoring using a Geographic
Information System (GIS). The data used is secondary data. The data used is the
Land Use Map, Map of Precipitation 2013-2017, Soil Texture Map, Slope-Land
Map and Spatial Planning and Administration (RTRW) Majalengka 2011-2031
Kabupaten Majalengka 2011-2031. The results showed that Majalengka has three
