PENGKAYAAN MIKROBA KONSORSIA PADA UREA BERLAPIS ARANG AKTIF DAPAT MEMPERCEPAT PENURUNAN INSEKTISIDA ALDRIN DI LAHAN SAWAH
Abstract: The challenge for
the Indonesian nation in the future is globalization which demands a very tight
competition. Three factors that support this are increased efficiency,
productivity and quality of agricultural products. The use of pesticides has
contributed most to the increase in agricultural production since 1970. The
amount of pesticides circulating in Indonesia from year to year increases. In
2006 there are as many as 1336 registered formulations, in 2008 the amount of
pesticide formulations are 1702, in 2010 there are as many as 2048
formulations, and in 2011 as many as 2247 formulations. Microbial enrichment is
expected to accelerate the degradation of residual insecticides aldrin . The
research is conducted at the Experiment Jakenan Station February 2012 to
September 2012. The soil which is used as the planting medium is brought from
the village of the District Sukamenak Rawagempol Wetan, Karawang. The
experiment was conducted in field scale microplot with lysimeter, and using a
randomized block design ( RBD ) 3 replications 6 fertilizer treatments (
control , prill urea , urea activated carbon maize cobs ( UAATJ ) , urea
activated carbon coconut shell ( UAATK ) , urea activated carbon cob corn +
microbes ( UAATJM ) , urea activated carbon coconut shell + microbes ( UAATKM
). The plants used are rice varieties inpari 13. The insecticide residue analysis
is performed in the Residu Bahan Agrikimia (RBA) laboratory Balingtan. The
purpose of this study is to obtain urea technology with activated carbon
enriched with insecticide degrading microbes that can degrade POPs aldrin
insecticide residues. microplot scale research results by using a lysimeter
showed the highest reduction of residual insecticides aldrin in the treatment
of urea -coated coconut shell activated carbon enriched microbial consortia
that degrade POPs is 36,17 % . It is suspected that coconut shell activated
carbon microbial favored as its home and the microbes utilize carbon sources of
aldrin as food for growth.
