Abstract
Domestic wastewater containing ammonia and phosphate are the main pollutants of toxin. Its affects the growth of aquatic plants, including of Eichhornia crassipes and Pistia stratiotes. The plants were placed outlet in anaerob, facultative, and maturation ponds in Wastewater Treatment Plant (WWTP) Bojongsoang, Bandung. Each of them consists of 9 individuals, during 14 days, from July to November 2012, with 6 replicates. The results was showed the growth of E. crassipes higher than P. stratiotes, in anaerobic and facultative ponds. The growth all part are increasing, except the root length. On E. crassipes, the range of growth of wet weight of 99.39–99.49 g, stolon length of 13.28–15.97 cm, leaf area of 1.12–8.56 cm2 and number of petiole of 17.58–18.84, relative growth rate (RGR) of 0.069–0.072 g/day, and doubling time (DT) of 9.7–10.5 day, and its sequentially on P. stratiotes 14.09–25.58, 4.58–6.69 cm, 1.50–2.43 cm2, 10.73–18.78, 0.044–0.073 g/day, and 10.0–17.0 day. Most of the highest values its found in the anaerobic pond, that is change of total chlorophyll which increased on E. crassipes (96.31 mg/L), but decreased in P. stratiotes (-6.03 mg/L).
