Pengaruh Variasi Dosis Penambahan Biochar Sekam Padi Terhadap Efisiensi Penyisihan Logam Berat Cd Dan Pb Pada Tanah Tercemar

---

ABSTRACT
Biochar has a large surface area, and a high capacity to absorb heavy metals and
can potentially be used to reduce bioavailability and leach of heavy metals as well
as organic pollutants in the soil through adsorption. This study aims to determine
the effect of adding biochar from rice husks to removal of heavy metals Cd and Pb
in contaminated soil. Biochar is made using a pyrolysis apparatus with a burning
temperature of 500oC for 1 hour. The dose variation used in this study was 10% ;
12.5% ; and 15% with 30 days incubation periods. Biochar from rice husks in this
study has met the requirements for activated carbon based on SNI 06-3730-1995,
with 2% of water content, 9.2% of ash content, 20.4% of volatile content, and
68.4% of fixed carbon. The results showed that the highest Cd and Pb removal
occurred at the addition of a 15% dose of biochar, so that the concentration of
heavy metal Cd became 10.85 mg/kg with a removal efficiency of 45.45%, and
heavy metal Pb concentration became 95.97 mg/kg with a removal efficiency of
51.71%.
Key words: biochar, rice husk, biochar dose, polluted soil, heavy metals
