Bioremediasi untuk Menurunkan Kadar Insektisida Klordan di Lahan Sawah
Abstract: Bioremediation is
one of the effective ways
to remediate pesticide-contaminated land,
in order to reduce environmental
pollution problems. Bacillus substillis, Heliothrix oregonensis, Catenococcus
thiocycli,and Achoromobacter sp are soil microbes which are capable of lowering
the levels of chlordanein the fields. These microbes derived from preliminary
research results indigenous soil insulation in the Laboratory of Microbiology LIPI
Cibinong. This research is aimed to determine the decrease levels of chlordane
in paddy fields cultivated with rice Ciherang variety using bioremediation
treatment. The soil used for the planting medium is taken from Cilamaya
village, District CilamayaWetan,
Karawang. This research is conducted at
Jakenan Research Station from January to December 2013. This research
uses activated carbon coated urea and
biochar enriched by indigenous microbes with
a dose 250 kg/ha. This research is designed by using complete
randomized block design
which is repeated
three times with for 40 ml microbial concorcia populations 109 in 1 kg
of urea coated by biochar or activated carbon. The microplot size 1 x 1 m with
spacing of 20 x 20 cm. Insecticide residue analyzes carried out in Balingtan
Laboratory in Bogor by gas chromatography, using the SNI 06-6991.1-2004method.
The result shows biochar
coconutshell-coated urea enriched
with microbes in
rice farming can
reduce pesticide residues
chlordane amountedto 27.10%
