Acid mine water refers to resulted from the oxidation of sulphide mineral a mining process and exposed water, it has high acid level which is indicated by low value pH that below 6. Therefore, must be treated so does not cause pollution in area around mine. In this research, treatment applied active method using jar test with neutralizer media powerbase. This research only calculated dosage necessity cost powerbase laboratory scale as well field scale. The need for was 80 kg Rp 752,000.00 once neutralization/hour. With 7,520,000.00 application 0.6 gram/1000 ml could increase 4.3 7.62.
