Acid mine drainage (AMD) contains high concentration of various heavy metals and low pH levels, ranging between 2-4. The water samples used for this research are an artificial AMD, with varying concentration levels of copper (5 and 7 mg/l). The pH level is designed to be 4, where the designed pH level illustrates the actual characteristics of an AMD. The data for this research-pH and copper levels-are taken for 14 days. This research shows that exposure of the artificial AMD causes physiological effects to Pistia stratiotes, indicated by chlorosis of the plant starting from day 3 of the research. Furthermore, the result of this research illustrates that Pistia stratiotes is able to alter the artificial AMD's pH level from 4 to 7,3 in 14 days. This plant is also capable of reducing the copper content as much as 92,45% and 88,00% with initial concentrations of 5,3 mg/l and 7,5 mg/l respectively in 14 days, with peak removal at day 3. It can be concluded that Pistia stratiotes is able to neutralize pH level and decrease copper contents in artificial AMD.
