Abstract

The purpose of this study was to find the most effective between rough horsetail (Equisetum hyemale) and Mexican sword (Echinodorus paleafolius) as a phytoremediation agent in reducing heavy metal lead (Pb). The method used in the study was an experimental method with a completely randomized design (CRD) consisting of four treatments and three replications using two aquatic plants, namely rough horsetail and Mexican sword. The physical and chemical parameters observed were temperature, degree of acidity (pH), dissolved oxygen (DO), and the concentration of heavy metal lead (Pb). The optimal research results on the combination treatment to reduce the concentration of heavy metal lead (Pb) was 0,0066 mg/L with a decrease proportion of 90,32% for 14 days. The best phytoremediation results in the rough horsetail and combination treatment used for fish with fish survival was 100%.
