UJI AKTIVITAS ANTIBAKTERI EKSTRAK HERBAL TERHADAP BAKTERI ESCHERICHIA COLI
ABSTRACT: Several herbs have
been evaluated as feed additive for chicken, namely tumeric, white tumeric,
javanese ginger and black ginger. The purpose of the research was to examine
antibacterial activity (inhibition diameter zone and minimum inhibition
concentration test) on several herbs extract toward Escherichia coli. In the
experiment, there were 6 treatments namely aquadest 100% (A0), antibiotic
tetracycline (A1), tumeric extract (A2), white tumeric extract (A3), javanese
ginger extract (A4) and black ginger extract (A5) in response to inhibit
Escherichia coli. Variables measured were inhibition diameter zone and minimum
inhibition concentration test against challenge on Escherichia coli. The
experiment was arranged in one way nested ANOVA based on completely randomized
design and if there were different effects among variables it would be tested
by Duncan’s multiple range test. The result showed that the use of turmeric
extract gave highly significant inhibition diameter zone for Escherichia coli
(P<0,01), further test indicated that as low as 50% (w/v) concentration of
turmeric extract was enable to show as minimum concentration of inhibition
against Escherichia coli. The conclusion of this research was among the herbs,
selected turmeric extract showed the highest inhibition diameter zone if
challance against Escherichia coli with minimum inhibition concentration of 50%
(w/v).
