SINTESA GEOMORFOLOGI ANTROPOSEN KAWASAN CAGAR ALAM GEOLOGI KARANGSAMBUNG BAGIAN SELATAN

Abstract

The earth's surface is experiencing dynamic developments, not only in changes in land use types but also in detailed geomorphological landforms. This dynamic change is caused by the human need for land. Java Island has a diverse physiography, this is due to volcanic activity and uplifting as well as erosion and sedimentation. Karangsambung area is an area with hilly topography and exposed many rocks which are evidence of tectonic processes. A lot of rock outcrops and in a relatively large area, resulted in agriculture not being dominant. The community tends to take advantage of the location as a place for mining. Mining carried out by the community in the Karangsambung area including rocks that have commercial functions. In addition, high erosion and sedimentation training in sand mining in the deposition area. Mining is carried out widely and gradually causes environmental problems. This study aims to see the impact of human activities on natural conditions in the southern part of Karangsambung Nature Reserve. The spatial approach uses remote sensing image data as an early indication. The results obtained are that in the Karangsambung area there are 3 human activities that cause changes in land shape, namely changes from alluvial plains to floodplains and fluvial plains. Changes in sinuosity due to sedimentation and landslides damage due to slope cutting, as well as changes from hills of diabas intrusion to degraded land with flat topography. These changes have a bad impact on the environment, resulting in handling from various sector.
