Abstract : Phytoremediation is one of the effective methods in the treatment of water pollutant. In this study, Colocasia esculenta, Pistia stratiotes, and Limnocharis flava were used in this study to remediate the contaminated aquaculture wastewater. The removal efficiency of parameter elements (Fe, Cd, and P), ability to increase DO, as well as accumulation of parameter elements (Al, Fe and Cd) were evaluated. Aquaculture wastewater taken from tilapia pond was used as influent to be treated in constructed wetland reactor tank with the selected plants. The HRT was set as 2 days for each of 6 batches. The plant sample analysis was carried out using Bruker S2 Ranger Energy Dispersive X-Ray Fluorescence (EDXRF) at the beginning and end of the whole set experiments, while the wastewater analysis was carried out using EDXRF and YSI 556 MPS before the experiment and for each batch. This study has shown the suitability to be used in phytoremediation of aquaculture wastewater was arranged ascending as Limnocharis flava < Pistia stratiotes < Colocasia esculenta.
