Kajian Rehabilitasi Lahan Dengan Aplikasi Analisa Citra Satelit dan GIS untuk Mitigasi Bencana

Abstract

Land rehabilitation is the reconstruction of the disaster areas to support disaster mitigation , can be carried out by the method of vegetative soil conservation . Rehabilitation and management of sloping lands by means of utilizing the right plants as a means of conservation , according to the geographical and topographical conditions This could be an alternative for land rehabilitation Glagahwero sub watershed area , Panti district , Jember regency , which in 2006 experienced flash floods . From the study before are known , flooding is caused due to erosive soils and land use change . The purpose of this study was to determine the suitability of the area function and physiological condition of the plants for support the rehabilitation process . Primary data used is the 2008 Aster satellite imagery and other supporting data , such as soil type maps, slope maps , maps of erosion , rainfall data and others. Analysis performed with Geographic Information Systems ( GIS ) . The results of the study are known , the protected forest area , covering an area of 1,000 ha that potentially critical and annual crop cultivation area covering 4200 ha , 50 % is potentially critical . Rehabilitation efforts must be made , by vegetative conservation methods , the plant is adapted by the area function and physiological conditions . The study showed that , as erosion control on protected forest areas can be selected sengon laut and kemlandingan . Teak , mahogany and sono keling for buffer zones and plant coffee , cacao , rambutan , durian , avocado , jackfruit , interspersed with salam and mahogany , for annual cultivation area . As for the edge of the river , as the amplifier terrace , can be planted with bamboo , salak and kaliandra .
