Study on Land Cover Change of Ciliwung Downstream Watershed with Spatial Dynamic Approach

Ciliwung watershed has a strategic value in Indonesia. As a watershed ecosystem, the changing of the upper stream, will affects the other part of watershed. The changing of the upper stream is closely related to flooding where the precipitation can’t be absorbed by soil because the decreasing of water catchment area. The condition of land cover is important to identify the watershed condition. The land cover changes data were analyzed from LANDSAT satellite image taken in four different years of 1990, 2000, 2010 and 2014. The land cover types were divided into four areas: water body, green area, bareland and built-up area. Analysis on land cover pattern indicates that water body area decreased 1.49% in 2014 compare 1990, followed by green area (0.28%) and bareland (0.19%) in total. Spatial dynamic approach will be used as an analysis of prediction on land cover change. The concept of dynamic system is to connect all the objects that interact each other to create a trend in the future.
