Abstract

This study is assessing the ecological integrity of landscape condition to maintain freshwater biodiversity at highly urbanized catchment using geographic information system (GIS). GIS tools were used to calculate the percentage of land use types i.e. impervious cover, vegetation cover, and water body at 6 sub-catchments of Universitas Indonesia (UI) Depok campus. In order to evaluate freshwater biodiversity, 478 samples of macroinvertebrates were collected from the cascade-pond system. Each of pond was calculated using macroinvertebrate indices namely Singscore and The Shannon Diversity Index. Nine parameters of water physics-chemistry were also collected from each pond and calculated based on The National Sanitation Foundation - Water Quality Index. The highest percentage of impervious cover is located in the upper of catchment and simultaneously reduce the percentage downward. The impervious cover affects the pattern of freshwater biodiversity and water quality the of cascade-pond system. The most diverse and highest score of aquatic organism was found at Salam sub-catchment that located in the lower part of UI catchment. Integrated assessment of UI catchment area using GIS-based multiple criteria decision analysis shows that the term of "end-of-pipe" at cascade-pond system affecting the ecological status of each catchment.
