Comparison of Characteristic Aquatic Local Plants for Phytoremediation with Different Media of Acid Mine Drainage Passive Treatment

Acid mine drainage treament using more passive methods to reduce costs and be more environmentally friendly. This passive method is to drain the acid mine water in wetlands that have been built with a suitable plant to neutralize the acid mine water and also to absorb the dissolved metal. The purpose of this study to determine the types of aquatic local plants suitable as a medium phytoremediasi and also to the extent to which organic matter compost/bokashi can increase pytoremediasi acid mine water compared to using the original medium acid mine drainage. Also to comparison result of the best one aquatic plants for phytoremediation, and than the plants selected will using for aerobic wetland of acid mine drainage passive treatment. The method used is sampling the a aquatic local plants at the mine and planted in acid mine drainage media and using 11 aquatic plants consist of 3 kinds as : Emergent, floating leaf and submersed with 2 design ( with add organic matter and without organic matter). The research results shown the design 2 (with organic matter on media) better than for Imprved pH and reduce metal Fe and Mn from acid compare with design 1 (without organic matter on media. Design 2 can improved pH average 131% from 2.54 to 5.86 and reduced Fe Average 54% from 3.00 ppm to 1.38 ppm, than reduced Mn 76% from 27.1 ppm to 6.48 ppm.This study shows that the local plant in the vicinity of the coal mining could be phytoremediasi plant in the treatment of acid mine drainage passive. Taro red (Colocasia esculenta- red), Kale Water (Ipomea aquatic), Water plants (Hydrilla Sp), Lotus (Nymphaea lotus L.) recommended for aerobic wetland system to passive treatment acid mine drainage for improvement pH level and reduced metal as Fe and Mn on acid mine drainage water.
