Abstract

Open-pit coal mining causes the formation of acid mine drainage (AMD) which has a low pH and high metal solubility. Efforts to absorb heavy metals and neutralize the pH of AMD can be done by phytoremediation. This research aims to monitor the effectiveness of Water chestnut (Eleocharis dulcis (Burm.f.) Trin. ex Henschel) in the accumulation of iron (Fe) and manganese (Mn) in AMD phytoremediation and to determine the mechanism. E. dulcis was taken from the constructed wetlands of wastewater treatment pond Air Laya 02 PTBA Tanjung Enim, South Sumatra, Indonesia with a convenience sampling method. Measurement of iron (Fe) and manganese (Mn) content using (AAS)-flame. The results showed that E. dulcis was able to improve the quality of effluent from inlet, wetland to outlet by increasing the pH from 5.6 to 7.7 and reducing Fe content from 7.89 ppm to 0.25 ppm, Mn from 1.72 ppm to 0.76 ppm, and sulfate (SO4) from 531.33 ppm to 405 ppm. The accumulation of Fe and Mn by the roots of E. dulcis were 890.00 ppm and 63.37 ppm with BioConcentration Factor (BCF) values of 18.56 and 1.77, respectively, indicating that E. dulcis has potential as a hyperaccumulator plant because the BCF value is more than 1. The mechanism accumulation of Fe and Mn metals by E. dulcis is phytostabilization because of the value of Translocation Factor (TF) less than 1. Phytoremediation by E. dulcis in constructed wetland system can manage AMD waste so that it fully fills the quality standards of wastewater from coal mining activities
