Abstract
Waste from the tofu industry produced the pollutant like NH3, NO2, NO3 with high content that caused environmental pollution. Hence, the processing of tofu liquid waste was needed. The purpose of this research was to determine the effect on the levels of pH, NH3, NO2, NO3 and to determine the biomass of water hyacinth. This research was an experimental research with three research namely tofu liquid waste 100% (control), sedimentation process and the phytoremediation of water hyacinth with 9 duplicates. Parameters measured include pH, NH3, NO2, NO3, and biomass. The Data were analyzed using the one-way ANAVA then continued with Duncan Test at 5% level and analogous to the quality standard of East Java Governor Decree Number 45 of 2002. The results showed that the phytoremediation of water hyacinth by sedimentation was able to increase pH levels from 4.21 to 7.37; reduce NH3 levels from 6.41 to 1.83; decrease NO2 levels from 1.94 to 0.61; decrease NO3 levels from 15.91 to 12.66; and increase the biomass of water hyacinth. The Phytoremediation of water hyacinth (Eichornia crassipes) by sedimentation can be used to improve the quality of liquid waste in accordance to the standard of quality for the parameters of pH, NO2 and NO3, NH3.
