Tackling mine acid water has been carried out chemically and physically so it is not efficient because it can cause new pollutants therefore, biologically the AAT prevention can use the bioremediation technique using sulfate reducing bacteria (BPS) which contains abundanthis research was aimed to analyze out the ability of mangrove sediment in water waste neutralization of acid mine, to analyze out the optimum Power of Hydrogen were produced by the mangrove sediment in water waste neutralization of acid mine, to find out the reduction of sulphate degree, heavy metal manganese and iron produced, to analyze out the texture of the best mangrove sediment in water waste neutralization.The sample of water of acid mine was taken from PT. Pasir Walanae, Lamuru Bone, mangrove sediment was taken from destination touristic of tongke-tongke sinjai. This research used analysis with descriptive method such as collecting the data field, sampling and trial at the laboratory.The finding of this research showed that the mangrove sediment was able to increasing the Power of Hydrogen and decreasing the sulphate degree, able to increasing the value of Power of Hydrogen from 2.24 became 7.02, the optimum Power of Hydrogen was achieved by using mangrove sediment with sand texture 7.02 at the tenth day. Decreasing sulphate degree from 1.171 ppm became 0.625 ppm by using mangrove sediment with sand texture 7.02 at the tenth day, but could not decreasing the content of metal manganese (Mn) and iron(Fe) by using mangrove sediment with sand texture and mud texture because the content of metal in that sediment was highest than the water of acid mine. The best texture of mangrove sediment in neutralization of acid mine was sand texture sediment because the time to neutralization of acid mine was more quickly in neutralizing the Power or Hydrogen and to increase the sulphate degree.
