摘要：Lead (Pb) is an element that is commonly used in various industries and is always present in various forms of the pollution, whether solid, liquid or gas (air), efforts to reduce Lead levels are very necessary considering this metal has many sources both naturally and as factory residue, fertilizers and pesticides. This research aims to restore and increase the productivity of the polluted rice fields by producing Pb-free rice. This study used a 2-factor randomized block design with 4 replications, the first factor was Biochar application; without Biochar (B0) and with Biochar rice husk (B1). The second factor using Azolla, namely; without Azolla (A0), with Azolla pinnata (A1) and Azolla mycrophylla. The results showed that giving Biochar rice husk and Azola was able to increase production up to 7.10 tons / ha, up 10% from control and reduce lead to 43.9% and the best azolla for paddy lead contaminated was Azolla mycrophylla.
