Abstract. Hospital waste can pollute the environment if it is not managed properly. There is a
special installation to treat wastewater from the hospital before it flows into the aquatic
environment. Each hospital must have a Wastewater Treatment Plant in accordance with its
standard provisions. Waste from a hospital in Bireuen was sampled in this study because it has
a characteristic blackish cloudy color and strong odor. This study aims to see the ability of water
plants Lemna minor L. and Pistia stratiotes L to have an effect on reducing COD, BOD, and
TDS in hospital waste. This research was conducted using experimental methods. Result data
show the effect of aquatic plants as phytoremediation in hospital waste. The results of this study
indicate that the Lemna minor L. and Pistia stratiotes L. have different tolerances to hospital
wastewater. Pistia stratiotes L. was able to adapt to high concentrations of waste while Lemna
minor L. was only able to survive at a waste concentration of 70%.
