Aktivitas Antibakteri Ekstrak Bronok (Acaudina molpadioides) terhadap Pertumbuhan Bakteri Staphylococcus aureus dan Escherichia coli

Bronok (Acaudina molpadioides) is a type of marine biota the phylum Echinoderms class Holothuroidea that can empirically increase stamina and have positive effects on health. One infectious diseases such as diarrhea caused by Escherichia coli Staphylococcus aureus bacteria which are still major problem in public health potential to cause death. Most these developed resistance antibiotics This study aims determine antibacterial activity extracts bronchus against growth bacteria. In addition, this uses disc diffusion method with concentrations 25%, 50% 75% sample used bronchoconstriction extract. The results bland zone diameter showed methanol extract was able inhibit an average 4.1 mm, 5.3 5.8 ethyl acetate 4.7 6.2 15.2 mm. Methanol 3.7 4.5mm, 5 bronok had extracts. has By looking at inhibition each solvent where larger zone, stronger activity.
