Selection of organic matter as a wetland substrate for acid mine drainage treatment

Acid mine drainage (AMD) is one of the problems arising from mining activities. formed due to oxidation sulfide minerals such as pyrite (FeS2) by water and oxygen. Alternative management AMD in a sustainable eco-friendly way constructed wetland. Therefore, this study was conducted determine type composition potential organic matter that can improve quality. The consisted three stages: screening matter, combination two matters, cow manure empty fruit bunches (EFB) various compositions. Types matters used are cow, goat, chicken manure, types compost, EFB, sawdust, wood chips, chopped hyacinth, cocopeat, fresh waste compost cajuputi leaf, citronella distillation, baglog waste, bagasse. results showed several could increase pH AMD. EFB with ratio 2:1 best result because it pH, reduce dissolved heavy metals sulfates, availability raw materials abundant nature, especially Indonesia.
