Abstract
Platycerium bifurcatum is an epiphytic fern, which belongs to the family polypdiceae and
genus platycerium. P. bifurcatum has been tested for phytochemistry and contains
secondary metabolite compounds. Several studies have been reported on this fern plant
for antibacterial activity testing. In this study, Gram-positive (Staphylococcus aureus
ATCC 6538, Bacillus subtillis ATCC 19659) antibacterial activity tests were carried out
from P. bifurcatum fern plant extracts. The results showed clear zone values from
dichloromethane extract and ethyl acetate extract in Gram-positive bacteria. Based on
antibacterial tests with diffusion methods in order to show moderate antibacterial activity
with the largest clear zone in ethyl acetate extract, which is 16.58±1.70 in B. subtilis
bacteria.
