Abstract

Jakabaring is an area in the Palembang City which has been growing rapidly for over last ten years. Most of this area has been developed for sport center, government office, business and commercial district, school, and residential areas since early 2000; which was formerly large lowland. Due to the rapidly increasing development, the lowland areas decreased which might lead to an increased risk of flooding. This study aims to analyze the land cover change within Jakabaring sub basin and its impact on surface runoff. Land cover change analysis was done using Semi-Automatic Classification plug-in installed on QGIS to Landsat images for year 2002 and 2013. The rational method was used in this study to estimate the peak runoff rate. The results of this study show that the vegetated area has decreased by as much as 527.83 ha (26.37%), while the built-up area increased by as much as 540.38 ha (27.00%). The decrease of vegetated area mostly due to the area was converted into built-up area. The land cover change within Jakabaring sub basin was estimated to increase the peak runoff rate about 30.23%. Hence, this condition could make the area become more risky to flood.
