Teknik Penginderaan Jauh dan Sistem Informasi Geografis untuk Identifikasi Potensi Kekeringan

Lukulo Upstream Watershed is watershed which located in Central Java with coordinate 340.000 - 365.000 mT and 916.0000 - 917.5000 mU. Human activities which still immeasurable influence the watershed condition, its exploitation of natural resouces (rocks, sand). In Lukulo Upstream Watershed there are seven sub watershed they are Lukulo sub watershed, Lokidang sub watershed, Maetan watershed, Gebang watershed, Loning watershed, Mondo watershed, and Cacaban watershed. Calculation using GIS (Geographic Information System) for deliberated erosivity index formula found that Lokidang watershed is first priority of watershed criticaly, value the deliberated erosivity index equal to 1082,62 broadly 3602,705 hectare. While from viewpoint land cover (vegetation) with remote sensing method transformation using NDVI (Normalized Difference Vegetation Index) Gebang watershed, Cacaban watershed, and Lukulo watershed is watershed which is very easy of damage (erosion) because the land surfaces which do not closed with vegetatation so erosion is easy.
