This study aims to investigate the characteristics of acid mine water from the water layer inside one of the existing voids in the coal mine site will be passive processing performed by using water as a medium phytoremediasi plants. Shingga be known acidity and heavy metal content of the surface layer, colloid (float), as well as sediment. Expected later found that plant species used as media bias wetlands in accordance with the characteristics of acid mine drainage in the area tersebut.Hasil showed the characteristics of each layer of the water into the acid mine water is different. More precipitate containing heavy metals Fe, Mn deposition is proportional to the number of parameters TSS. Result analysis show that characteristics of acid mine water at 4 void on the bottom layer (sludge) contains more heavy metals than the type of Fe and Mn in the middle layer (colloidal) and upper layer (surface), namely: 0.97-1,97 ppm for Fe and 12.12 to 12.40 ppm for Mn. But to the degree of acidity/pH on the third layer is more or less the same at the rate of 3:03 to 3.04 ppm. Especially for Void M2W was found that the water quality parameters of pH for the better in depth. Fe and TSS increasingly lower quality in comparison to the surface, except for Mn lower water quality in the middle/drift - colloid (50 - 75 cm) compared with the inside and the surface (25 cm and 100 cm). Recommended for the management of acid mine drainage passive phytoremediation method chosen variations in root crops, drift and surface in order to reduce heavy metals from acid mine drainage each layer.
