Water quality is very important for human life. On the other hand, human activity can make the quality of river water getting worse especially on heavy metal content. The heavy metals which commonly contain in water are Zinc, Manganese and Iron. Then, to reduce the concentration of heavy metal, people can use quatic plants namely water hyacinth and water lettuce. Based on the result, the heavy metal contain already reduce into <0.05 for Fe, <0.03 for Mn and <0.005 for Zn in Day 4 with water hyacinth; moreover the amount of Fe, Mn and Zn already decreased to <0.05 for Fe, <0.03 for Mn and <0.005 for Zn in Day 4. Both of the aquatic plants showed similar performance of Fe, Mn and Zn. It can be proven from the result of T test. Therefore, there is no significant different between water hyacinth and water lettuce on heavy metal concentration in water.
