A river buffer strip is a vegetated area along river water bodies that protect and conserve river functions and eco-drainage of watershed. Currently, buffer strip quality has degraded by many land use conversion to settlement area. The critical condition of river buffer strip is more vulnerable in urban areas. Urbanization is also a driving factor for emergence of settlements at the banks of river in urban area. This land conversion may disrupt ecological functions of river buffer strips as well as river functions. The disruption of river functions may increase flooding risk that would be harmful to human community as well. Cisadane River is a large river that crosses many cities - one of them is South Tangerang City. This study aims to map and analyse land use changes in Cisadane river buffer strip. Land use change analysis based on satellite image data coverage in 2010 and 2015 using Geographic Information System. Source of land use data from google earth image. The result showed that in 5 years period, land built up has increased up to 1.04%, agricultural land has decreased up to 2.24%, the shrubs has increased up to 13.40%, open field has increased to 2.49%, stands vegetation has decreased to 15.73%, and water bodies has increased to 1.04%. The land use changes of Cisadane River buffer strips show a negative change - there is increasing built up land, open field, and shrubs; but declining stands vegetation. Changes in land use also do not disregarding river buffer designation; therefore those changes can disrupt ecological functions and give negative impact to river and watershed.
