The study area is a part of Lojing and it lies between latitude 4° 45’ 30” N – 49’ 0” longitude 101° E 48’ 30”E. This was focused on assessing vulnerable locations landslide based satellite imageries different years (2006, 2014 2015) which selected for visual interpretation vegetation indices (VIs). As result, there were 18 determined had occurred. With the aid historical imagery obtained quant...

Remote sensing has frequently been employed to monitor extreme climatic events, especially droughts, by identifying the anomalies of vegetation activity from regional global scale. However, limited research addressed performance remote on detecting precipitation events. By using Middle and Lower Reaches Yangtze River (MLR-YR) in China as an example, this paper examines application satellite-der...

An unmanned aerial vehicle (UAV), widely known as a drone, proves very effective in assessing cropping or crop cultivation. Its practical use evaluating corn cultivation technology systems is feasible when based on farmer participation. UAV can generate the Normalized Difference Vegetation Index (NDVI) algorithm that reflects greenness of leaves, which parameter related to photosynthesis and pl...

Mangrove ecosystem in Semarang City has an important role for survival of the coastal area. This is due to function mangroves as a barrier erosion, wave barrier, carbon producer, habitat biota areas, well improving water quality. However, time goes by, condition decreasing every year and causing disasters such erosion tidal flooding which have identically occurred on coast Semarang. area 2020 1...
