Abstract – This research study was conducted to determine the potency of the Santan
flowers to inhibit the growth of the two selected bacteria. It underwent the processes:
collecting, washing, weighing, and extracting of Santan flowers, preparation of culture
media, paper discs distribution to the plate of bacteria, incubating the plate of bacteria, and
measuring of inhibition zone.
The researcher used the Complete Randomized Design (CRD) to identify and find
out its capability. The components of each treatment were as follows: Treatment 0 contains
the control variable which is the Cloxacillin and Ceftazidime; Treatment 1 contains 50%
concentration of Santan flowers extract; Treatment 2 contains 75% concentration of santan
flowers extract; and Treatment 3 contains 100% pure concentration of santan flowers
extract.
Data revealed in terms of zone of inhibition (mm) that the Fcomp (1.33 and 4.33) is
less than Ftab, it implies that there is no significant difference between the 3 experimental
treatments there they are comparable to each other. Moreover, Tcomp value of (10.9961
and 10.0060) for Treatment 3 which yielded the highest mean value of (14.67 and 15.33) is
greater than the Ttab value of (2.776), it implies that there is a significant difference between
the experimental treatment and the commercial available in inhibiting the growth of
Staphylococcus epidermidis and Acinetobacter baumannii. Therefore, Santan flowers
extract is effective in inhibiting the growth of skin-infectious bacteria Staphylococcus
epidermidis and Acinetobacter baumannii.
Keywords: Santan flowers, Staphylococcus epidermidis, Acinetobacter baumannii
