dc.description.abstractThe aquaponic system is principly a culture technique combining an aquaculture and hydroponic in which fish and plant are reared together in a one system to improve the productivity and benefit of fish culture. In this research, the aquaponic system is made up of nine (9) units of ponds with vegetables substrate as biofilter. Ipomea aquatica ( Kangkung ) used as a economic vegetable in this system. The test used Multiple location of land tophografis which is : a).High, b) midle and c) low land. Differences of land tophografis apparently biodiversity of water plankton and water invertebrate which is important in food chain and ecologis balanced. In this research, plankton and macrobenthos samples taken regulary each week. 4% formaldehide use to conserved sample for laboratoies identification. Species identification, Diversity index (H’) and Heterogeneous species (E) from Shannon-Weaner use as indicator of biodiversity. All data experiment are analyzed descriptively. Nile tilapias (Oreochromis niloticus) were stocked 100/m2, feeted with dry pellet in dosis of 5% to the total biomass, was given two times a day. Fish rearing done on 2 moths. Result shown that plankton species from all test location are similar which is Chlorophyceae dominated the fitoplanton. Zooplanton was found in low number such as Rotifer and Enteromostraca. Plankton density in range of mesotrophic to eutrophic (2000-5000 cel /l). , Diversity index (H’) 0.75-1.57, Heterogeneous species (E)indicated low while Lemnaea sp dominated species of macrobenthos in range of 1 – 6 ind/m2 in size of 2 – 14 cm length. Aquaphonic system be stable at each location. Key word : multiple location, plankton and macrobenthosen_US
