Phytoremediation is an emerging technology nowadays due to demand in environmental sustainability which requires cost-effective solutions in terms of capital and operational cost. The treatment gain attention due to their potential in wastewater treatment especially in organics, nutrients, and heavy metal removal of domestics, agricultural, and industrial wastewater treatment. Plant functions in phytoremediation make the plant selection as an essential element. The plant should have the ability to tolerate with the toxic effluent and able to uptake the contaminant. Cyperus alternifolius (umbrella grass) was chosen as aquatic plant due to the ability to tolerance in municipal and industrial effluent sources with strong and dense root systems. Thus, the objectives of this study are to determine the potential and effectiveness of Cyperus alternifolius in the palm oil mill effluent treatment especially in the removal of organics (COD), nutrients (NH3-N and TP) and suspended solid. The batch experiment was run using Cyperus alternifolius to determine their potential of aerobic pond effluent for 21 days of treatment. Cyperus alternifolius treatment shows the great removal of COD and TSS with 96% and 91%, respectively at the end of 21 days of treatment. Nutrients removal achieved the maximum removal of 92% NH3-N and 99% TP shows after 11 days of treatment and percentage slowly decrease until the end of 21 days of treatment. Cyperus alternifolius had shown potential in the palm oil mill effluent treatment and can be combined with ponding treatment to enhance to water quality prior discharge.
