Skin infections most often found in developing countries, especially in the tropics, are purulent skin inflammation (pyoderma), the main cause of Staphylococcus aureus. The increasing number of cases of bacteria that are resistant to antibacterial can encourage the extraction of sources of antibacterial drugs from natural ingredients. One of the plants that is thought to have the antibacterial activity of Staphylococcus aureus is the Neem plant. In this study an antibacterial activity test was carried out with the well diffusion method from 96% ethanol extract of Mimba leaves extracted by percolation method. Previously 96% ethanol extract from Mimba leaves had been identified by secondary metabolites by phytochemical screening and standardized extract testing. Standarization using non-specific parameters (moisture content, ash content and drying losses) found that 96% ethanol extract of Mimba leaves entered a range of standard parameters and in phytochemical screening tests obtained 96% ethanol extract of Mimba leaves containing alcaloid, saponins, tannins, steroids / terpenoids and flavonoids. The results of the study on the antibacterial activity test showed a concentration of 75% ethanol extract of 96% Mimba leaves classified as having strong activity, at a concentration of 50% and 25% classified as having moderate activity. Based on this study it can be concluded that the three concentrations of 96% ethanol extract of Mimba leaves were able to inhibit the growth of Staphylococcus aureus bacteria.

Brown seaweed is one of the natural resources of the sea which is very abundant and grows naturally on the coast of Indonesia, especially in Madura. Lately, disease due to infection is one of the problems in the health sector that continues to grow. Some microorganisms that cause infections include bacteria, viruses, fungi and protozoa. One of the bacteria that can cause infection is Staphylococcus aureus. Staphylococcus aureus is one of pathogenic bacteria that cause abnormalities and infections to skin. The more infections cause an increase in the use of antibiotics, the greater the risk of increasing the incidence of resistance. This encourages the research of sources for antibacterial medicines from natural materials, namely macro algae. One of the macro algae that have antibacterial activity is brown seaweed from Padina australis species. This study uses laboratory experimental methods aimed at proving the antibacterial activity of 96% ethanol extract of brown seaweed Padina australis from the Madura Islands against Staphylococcus aureus ATCC 25923. The antibacterial activity test was carried out by the well diffusion method. The results of the antibacterial activity test showed that ethanol extract of 96% brown seaweed Padina australis with concentrations of 20%, 15%, 10%, and 5% had antibacterial activity against Staphylococcus aureus ATCC 25923 in the medium to strong category. Statistical test results (Kruskal Wallis) showed that there was a significant difference between the concentration and the inhibited zone produced (p = 0.037).

Five traditional herbal preparations were sampled between May-June, 2009 in Kano. The samples were investigated for invitro antibacterial activities against clinical isolates of Staphylococcus aureus. Likewise, phytochemical screening tests were conducted to determine some of the phytochemicals present in the ethanolic and water extracts of the samples. Various concentrations of the extracts were prepared using serial doubling dilutions (5000=l/ml, 2500=g/ml, 1250=g/ml, 625=g/ml and 312.5=g/ml). All the test extracts showed slight antibacterial activity against the test organism, with ethanolic extract of sample E having the highest zone diameter of inhibition, while sample H had the lowest diameter of inhibition. The standard antibiotic disc (Gentamicin) had demonstrated the highest activity on the test organisms. The results of the Phytochemical screening revealed the presence of steroid in all the samples, tannin in samples A, C, D and E, reducing sugars in sample A, D and E respectively. The result of the minimum inhibitory concentration (MIC) was found to be above 312.5=g/ml for samples C, D and E. Keywords: Staphylococcus aureus, Herbal preparations, antibacterial activity, Phytochemical screening and minimum inhibitory concentration.
