    Abstract
    Rice is the food of the majority of the Indonesian people who have not been replaced, hence production and quality have become a system of national security. Recently and most surprising and worrying thing is that rice turns out to be a hyper accumulator plant, which is a plant that can accumulate heavy metals in parts of the plant tissue without disturbing its physiological processes, it has become concerned about the accumulation of heavy metals in the grain to be consumed in the form of rice . The establishment of a factory in the rice field area complements the concern. Lead (Pb) is a heavy metal that is commonly used in various industries and is always present in various wastes. The purpose of this study was to obtain a technology package for increasing production of paddy rice without Lead (Pb) on polluted land using biochar and azolla. This research consists of 3 stages of research. The first study was the identification of the potential of biochar in absorbing Lead from 4 types of biomass sources, namely; rice straw, rice husk, coconut fiber and oil palm empty bunches. This potential is based on the analysis of biochar morphology, surface area, biochar porosity and functional groups and the chemical properties of biochar. This research was conducted at McGill University Mc Donald campus, Faculty of Agricultural and Environmental Science, Saint Anne De Bellevue Canada, in September - December 2013 as a comparison of azolla compost used. The results of the study, showed that biochar and azolla are very potential as absorbers of Pb, the most potent biochar in Pb uptake is rice husk biochar.
     
    Beras merupakan makanan mayoritas masyarakat Indonesia yang belum dapat tergantikan, sehingga produksi dan kualitasnya telah menjadi sistem dalam ketahanan nasional. Hal yang terbaru dan sangat mengejutkan serta mengkhawatirkan adalah bahwa padi ternyata merupakan tanaman hiperakumulator, yaitu tanaman yang dapat mengakumulasi logam berat pada bagian jaringan tanamannya tanpa menganggu proses fisiologisnya, sehingga telah menjadi kehawatiran akan adanya akumulasi logam berat pada bagian gabah yang akan dikonsumsi dalam bentuk beras. Berdirinya pabrik di kawasan persawahan melengkapi kerisauan tersebut. Timbal (Pb) merupakan logam berat yang umum digunakan pada berbagai industri dan selalu hadir dalam berbagai limbah. Tujuan penelitian ini adalah untuk mendapatkan paket teknologi peningkatan produksi padi sawah tanpa Timbal (Pb) di lahan tercemar dengan menggunakan biochar dan azolla . Penelitian ini terdiri atas 3 tahap penelitian. Penelitian pertama adalah identifikasi potensi biochar dalam menjerap Timbal dari 4 jenis sumber biomassa yaitu; jerami padi, sekam padi, serabut kelapa dan tandan kosong kelapa sawit. Potensi ini didasarkan pada analisis morfologi biochar, luas permukaan, porositas biochar dan gugus fungsional serta sifat sifat kimia pada biochar. Penelitian ini dilaksanakan di Universitas McGill kampus Mc Donald, Fakultas Agricultural and Environmental Science, Saint Anne De Bellevue Kanada, pada bulan September - Desember 2013 sebagai pembanding digunakan kompos azolla. Berdasrakan hasil penelitian dapat diketahui secara fisik bahwa biochar dan azolla sangat berpotensi sebagai penjerap Pb, biochar yang paling berpotensi dalam penjerapan Pb adalah biochar sekam padi.
