Abstract:
Research on phytoremediation of palm oil wastewater by Typha angustifolia within constructed wetland (CTW) as learning source for high school was conducted. The aim of this research is to observe potency of T. angustifolia within constructed wetland in improve palm oil wastewater quality. Free Water Surface of CTW was use in this research, compiled into one set that consist of 4 basin. Palm oil waste water was discharged into basin with Typha angustifolia plant respectively form: (A) Palm oil wastewater pass basin 1st, (B) Palm oil wastewater pass basin 2nd, (C) Palm oil wastewater pass basin 3rd, (D) Palm oil wastewater pass basin 4th. Parameter to be measured are BOD, COD, TSS, oil, and pH, analyzed at 1st, 4th, 8th, and 12th week after discharged. Data were analyzed by description analysis. The experiment results showed that BOD value was decrease attain 95.21%, COD value was decrease attain 91.36%, TSS value was decrease attain 99.07%, oil/grease value was decrease attain 94.09%, while pH value still within the range of quality standard. T. angustifolia could be used for palm oil wastewater treatment by phytoremediation. The results of this research could be used as alternative learning source in the form of Student Assignment Sheet on environmental pollution concept for grade X high school student.
