The influence of riparian characteristics on the diversity and abundance of macroinvertebrates at cascade-pond system universitas Indonesia Depok

Abstract

At the Universitas Indonesia (UI) there are six cascade-pond water quality decreased from year to year. This can be seen in plain view, on the change of water color, odor, and the amount of solid waste that is in cascade-pond that comes from outside the UI. The decrease of water quality is one of the reasons caused by land use change in UI Water Catchment Area. Previous studies tested the condition of waters with biological parameters. Biological parameters were tested using macroinvertebrate as a biological indicator, with the result of Average Score Per Taxon (ASPT) index proved that Kenanga cascade-pond include in heavy polluted. Agathis, Mahoni, Puspa, and Ulin is moderately polluted, and Salam is lightly polluted, resulting a hypothesis that the conditions of the UI riparian affects most to the diversity and abundance of macroinvertebrates (Fadillah, 2017). In this study to prove the effect of riparian characteristics on macroinvertebrates using Tropical Rapid Appraisal Riparian Condition (TRARC) Version 1 for the riparian, and the Average Score Per Taxon (ASPT) index for macroinvertebrates, the result proves that the value of riparian conditions affects the diversity and abundance of macroinvertebrates, evidenced from the results of R (0.1 - 0.7) with the correlation results (0.1 - 0.5) and the value of riparian pressure also affects the diversity and abundance of macroinvertebrata, this is evidenced from the results of R (0.01 - 0.6 ) with correlation result (0,05 - 0,6)
