Abstract: Patikan kerbau leaf contains alkaloid, flavonoid, phenol, and tannin can potentially be an antibacterial. The purpose of this research is to test the resisting potency of patikan kerbau leaf extract against Staphylococcus aureus (ATCC25923) dan Escherichia coli (ATCC11229). This was an experimental laboratory study using modified Kirby-Bauer with well diffusion technique at Research and Microbiology Laboratory of MIPA Faculty, Sam Ratulangi University Manado. Patikan kerbau leaf extract was obtained by using 96% etanol maceration. Extract concentrations used in this study were 50 mg/ml, 25 mg/ml, 12.5 mg/ml and 6.25 mg/ml. Ciprofloxacin was used as the positive control and CMC as the negative control. The CMC showed no inhibition zone. Ciprofloxacin had the widest zone of inhibition. The average of inhibition zone diameters produced by ciprofloxacin was 33,3 mm on S. aureus and 33 mm on E.coli. Euphorbia hirta leaf extract concentration of 50 mg/ml resulted in average inhibition zone diameter of 18.83 mm on S.aureus and 17.83 mm on E.coli. Extract concentration of 25 mg/ml resulted in 17.33 mm on S. aureus and 16.83 mm on E.coli. Extract concentration of 12,5 mg/ml resulted in 15.5 mm on S. aureus and 14.83 mm on E.coli. Then, extract concentration of 6.25 mg/ml resulted in 15.16 mm on S. aureus and 13.3 mm on E.coli. Conclusion: Extract of Euphorbia hirta leaf has potential inhibitory effect towards bacterial growth of S. aureus and E. coli. Moreover, the inhibitory effect of Euphorbia hirta extract is greater towards S. aureus rather than E.coliKeywords: antibacterial, patikan kerbau leaf extract, S. aureus, E. coli Abstrak: Daun patikan kerbau mengandung alkaloid, flavonoid, fenol dan tanin yang berpotensi sebagai antibakteri.

<p>This study aims to determine the antibacterial activity of C-4-methoxyphenylcalix-[4]resorcinarene modified by Hexadecyltrimethylammonium-Bromide (Resorcinarene-HDTMA-Br) against <em>Staphylococcus aureus</em> and <em>Escherichia coli</em> bacteria. The study was conducted by testing the inhibition zone diameter with paper disc diffusion method. Variations in the concentration of the sample used were 10%; 15%; 20%; 25%; and 30% b/v. In this study, Dimethyl sulfoxide (DMSO) (sampel solvent) was used as a negative control and Chloramphenicol as a positive control. It was found that Resorsinarene-HDTMA-Br had higher antibacterial activity than the unmodified C-4-methoxyphenylcalix[4]resorcinarene (CMFKR) against the <em>S.</em><em> </em><em>aureus</em> bacteria. Both CMFKR and Resorcinarene-HDTMA-Br are not active against <em>E. coli</em>.</p>

Nowadays many plants can be used as traditional medicines to overcome various diseases including infections, because the use of traditional medicines is relatively safer compared to drugs derived from chemicals. One of the local plants in Southeast Sulawesi that has been empirically used as a medicine for wounds is a race of plants. Komba-komba leaves (Chromolaena odorata) containcompounds alkaloid, flavonoids, tannins, phenols, triterpenoids, saponins and steroids which have their respective functions in inhibiting the growth of microorganisms or antibacterial. This study aims to determine the inhibition of komba-komba leaf extract (Chromolaena odorata) on the growth ofbacteria Staphylococcus aureus. This type of research is experimental laboratories. The method used was agar diffusion with 5 treatment concentrations, namely komba-sheep leaf extract concentration (Chromolaena odorata) 20%, 40%, 60%, 80% and 100%, positive control (tetracycline) and negative control (aquadest) and repetition . The results showed that there was a inhibition zone of komba-komba leaf extract (Chromolaena odorata) on the growth ofbacteria Staphylococcus aureus at a concentration of 20% at 2 mm, a concentration of 40% at 3.7 mm, a concentration of 60% at 4.7 mm, a concentration of 80% 6.2 mm and a concentration of 100% by 8 mm.

Abstract: In this his study we used endophytic fungi isolated from the roots of mangrove Avicennia marina growing on tidal zone around Tasik Ria Minahasa, North Sulawesi. The fungi were isolated and then tested the antibacterial effect against Staphylococcus aureus and Escherichia coli. Potato Dextrose agar was used in order to isolate the target fungi. The fungi began to grow on the second day after inoculation. Differentiation and purification processes to isolate the fungus obtained by observing fungi mycelia. While, the antibacterial activity test was following agar diffusion assay by planting 10 mm diameter of fungal mycelium together with particular bacteria onto the combination media. Ciprofloxacin was used as a positive control. The results shows a visible bacterial inhibition zone around the growing fungi with a diameter between 18 mm to 20.4 mm. Based on the results, it can be concluded that endophytic fungi isolated from the roots of mangrove Avicennia marina is able to inhibit the growth of S.aureus and E. coli.

The background of this study is Staphylococcus aureus is an anaerobic facultative bacterium and one of the normal microflora in the mouth. However, if it is influenced by predisposing factors, it will become a pathogen. Bidara leaves have antimicrobial activity against Staphylococcus aureus, because Bidara leaves contain various compounds including alkaloids, flavonoids, steroids, tannins and essential oils. The purpose of this study was to determine how much inhibitory power produced by Bidara leaf extract on the growth of Staphylococcus aureus bacteria. This research method is a laboratory experimental research using the diffusion test (wells) method. The sample of this study was Staphylococcus aureus. Dilution of Bidara leaf extract consists of 5 concentrations including: 20%, 40%, 60%, 80%, and 100%. Chlorampheniocol is used for Positive control while Negative control uses aquadest. Based on observations show that the average diameter of inhibitory zone Bidara leaf extract at a concentration of 20% with a diameter of 10.5 mm (R), at a concentration of 60% and 80% with a diameter of 16 mm and 18 mm (I), at a concentration of 100% with a diameter of 24 mm (S). It can be concluded that the higher the concentration of Bidara leaf extract, the inhibition zone formed will increase. So Bidara leaves are good for use in treating infections caused by Staphylococcus aureus bacteria.
