KEMAMPUAN DAYA HAMBAT BEBERAPA MACAM SABUN ANTISEPTIK TERHADAP PERTUMBUHAN STAPHYLOCOCCUS AUREUS DAN ESCHERICHIA COLI
ABSTRACT: This research
is aimed to find out ability some kind antiseptic soaps inhibiting the
growth of Staphylococcus aureus and Eschericia coli bacteria. The research
method used Randomized Completely Block Design Sub Sampling with 6 treament and
3 replication, they are: antiseptic soap A, B, C, D, phenol 2% and aquadest.
The group consist of S. aureus and E. coli bacteria. The inhibit experiment was
done by using Kirby-Bauer methode. The parameter analyzed by using Analysis of
Variance (ANOVA) continue with the Duncan’s Multiple Range Test (DMRT). The
result showed that there were
significant differences of inhibit zone that formed from both bacterias
. The result of the antiseptic soap suspend inhibit zone, S. aureus bacteria
has larger diameter than E. coli. Soap A, B, C and D with 50% concentrate
toward both bacteria, each has average diameter 25, 16 mm, 15,6 mm, 11,5 mm and
9,83 mm while phenol has 15,0 mm. This
result showed that soap A, B, and C has the equal ability to phenol 2%. Base on
Duncan Multiple Range Test (DMRT), it is found out that the real differences of
the inhibit zone between the two bacteria as well the real differences of
treatment forward those bacteria (P<0,05).
