Aktivitas Antibakteri Ekstrak Etanol Daun Harendong Bulu (Clidemia Hirta) asal Maluku terhadap Staphylococcus Aureus

Abstract

<p><em>Pleroma urvilleanum (Clidemia hirta) is a plant that is widely found in Maluku, which contains chemical compounds, including tannins (catechols and pyrogalotanins), dioxyanthraquinones, steroids, saponins, glycosides and phenols which of these contents can function as antibacterial. This study aimed to determine the antibacterial activity of the ethanol extract of Pleroma urvilleanum(Clidemia hirta) leaf from Maluku with various concentrations of 5%, 25%, 50% and 75% against the growth of Staphylococcus aureus bacteria. The research design used is an experimental laboratory using the agar diffusion method by means of wells. The results of the study showed that at a concentration of 5%, it has an inhibitory power of 20 mm with a strong category. While at a concentration of 25% it has an inhibitory power of 29 mm, at a concentration of 50% it has an inhibitory power of 34 mm and at a concentration of 75% has an inhibitory power of 35 mm with a very strong category. Conclusion: ethanol extract Pleroma urvilleanum (Clidemia hirta) leaf from Maluku has antibacterial activity against the growth of Staphylococcus aureus bacteria and the higher the concentration, the greater the antibacterial activity.</em></p><p><em>Keywords: Antibacterial activity</em>, <em>Harendong bulu (Clidemia hirta)</em>, <em>Staphylococcus aureus, Moluccas</em></p>

The Potential of Sea Urchin (Diadema Setosum) Extracts as Antibacterial Against Staphylococcus Aureus

“…The results of the study [37] are nearly identical to those of the study [39], where the ethyl acetate extract from sea urchin shells as a whole exhibits antibacterial activity against the growth of Staphylococcus aureus with an inhibition zone diameter of 7.67 mm, as opposed to the study Hardani et al [40] , where the inhibition zone formed with sea by earlier research, Staphylococcus aureus growth is reported to be inhibited by ethyl acetate extract from sea urchin shells. This is a manifestation of the flavonoids, alkaloids and tannins found in sea urchin shells, which have antibacterial properties [41][42][43].…”
