Sensitivity of pathogenic bacteria to buah merah (Pandanus conoideus Lam.)

Research has been conducted on the sensitivity of pathogenic bacteria to buah merah (Pandanus conoideus Lam.). The method used are the Kirby-Bauer method. The results showed that all test bacteria sensitive to the antibiotic chloramphenicol 30 µg, 10 µg streptomycin, vancomycin 30 µg, gentamicin 10 µg and sulfonamide 300 µg. Bacterial sensitivity test results showed that fraction of water from buah merah can inhibit Salmonella typhi (14.78 mm), Bacillus cereus (15.72 mm) and Streptococcus pyogenes (14.44 mm), hexane fraction can inhibit S. typhi (9.94 mm), Escherichia coli (8.94 mm), B. cereus (9.33 mm), S. pyogenes (9.94 mm), Butanol fraction can inhibit E. coli (14.56 mm), Fraction ethylacetate can inhibit K. pneumoniae (14.56 mm), Staphylococcus aureus (14.39 mm) and ethanol extracts can inhibit Klebsiella pneumoniae (8.28 mm), S. aureus (8.67 mm), The effective concentration of buah merah in inhibiting bacterial growth is 80 %, on S. typhi (32 mm), E. coli (20.87 mm), K. pneumoniae (20.27 mm), S. aureus (21.13 mm) and S. pyogenes (19.47 mm). There are differences in sensitivity between buah merah and antibiotics against bacteria, where the buah merah inhibitory zone was smaller than the antibiotics.
