Abstract

Wickered-constructed floating wetland in the Gedebage pond was built as an integrated tourist attraction with the floating mosque. According to the governing ordinance, it should conform to the quality standard requirements. This study aimed to assess the pollutant removal efficiency of constructed floating wetland from domestic waste in the Cinambo river as an influent on the pond and the pond's ecological status. The assessment of ecological status was based on three methods: 1) the physicochemical index using the pollution index (PI) and the water quality index (WQI), 2) the biological index using phytoplankton diversity including the trophic index, and 3) canonical correspondence analysis (CCA) describes the multivariate correlation between the physicochemical index and the biological index. The results indicated a pollutant removal efficiency of total dissolved solids (TDS) was 46.5-49.5%, of total suspended solids was (TSS) 33.5-39.8%f biochemical oxygen demand (BOD) was 34.0-37.3%, of chemical oxygen demand (COD) was 11.8-17.5%, of total nitrogen (TN), was 76.3-79.6%, of total phosphate (TP) 89.1-89.9%, of boron (B) was 29.7-54.5%, of detergent (MBAS) was 72.9-82.2%, and of dissolved oxygen (DO) was 2.8 to 3.6 times. The ecological status indicated the improvement of water quality from heavily polluted in influent to lightly polluted in the pond (PI) and changed from poor to fair (WQI), the same results with biological index were indicated in moderately polluted after treatment. However, trophic index results showed the pond was in eutrophic to hypertrophic condition. CCA indicated eutrophication was correlated to the abundance of Microcystis and Lyngbya genera.
