The upstream Ciliwung watershed is one of the watersheds which in critically condition and need to be handled seriously. It was indicate that the environmental carrying capacity has been decreased by the land use changing.The method for the carrying capacity calculation was refer to the regulation issued by Ministry of Environment number 17 year 2009.
