Skin cream, is one of the dosage forms, which contain little water content, and is widely used both as a medicinal and cosmetic cream. This study made an herbal cream formulation based on Agung Semeru banana skin of Lumajang variety which was known as an antimicrobial at a concentration of 100% which would then be tested for its ability as an antimicrobial against the growth of Candida albicans and Staphylococcus aureus. The method used in this study is using the paper disk Diffusion method with 6 repetitions, where data in the form of inhibitory zone diameters were analyzed using 1% One Way ANOVA test and continued with Duncan's test at 1%. The results of this study showed that there were significant differences between the treatment groups (α = 0,000), where the cream formulation of the Candida albicans fungi showed a larger inhibition zone diameter (22.50 ± 1.70 mm) than the inhibitory zone diameter in Staphylococcus aureus bacteria (21 , 50 ± 1.68 mm).

The leaves of kenikir are known to have many benefits, one of which can be used as medicine. Kenikir leaves are reported to have antibacterial activity against the bacteria Salmonella typhi (S.typhi). S. typhi is a bacterium that causes typhoid fever. Typhoid fever is still an endemic disease in Asian countries, especially Indonesia. Typhoid fever became the third largest disease in Indonesia in 2010. The study related to the antibacterial activity of kenikir leaf fraction to S. typhi has never been reported. Therefore, it is necessary to conduct research related to the antibacterial activity of extracts and leaf fractions of kenikir to compare their potential against S. typhi. The study was conducted using the disk diffusion method using 5 series of concentrations namely 5%, 10%, 15%, 20%, and 30%. Tests were carried out on methanol extract, hexane, ethyl acetate, and methanol-water fraction. The results showed that highest inhibition zone diameter is 7,75 mm which is reached by methanol extract. The order of the highest inhibiting zone diameter are extract, hexane, ethyl acetate, and methanol-water fraction.

Different concentrations of ethanolic extracts of thyme (Zataria multiflora) and rosemary (Rosmarinus officinalis) were evaluated to determine their antimicrobial activity using the agar-well diffusion method. The values of inhibition zone diameter (IZD) for Candida albicans fungus and Staphylococcus aureus Gram-positive bacteria were determined. The bioactivities of two various extracts were studied, and the chemical composition of the extracts were identified using gas chromatography-mass spectrometry (GC-MS) technique. The results of the test showed that at concentrations of 10% and 40% thyme extract, the values of IZD were 12.5 mm and 23.3 mm, respectively, against the growth of S. aureus, which were higher than C. albicans (7.0 mm and 22.5 mm, respectively). The rosemary extract at concentrations of 20% and 60% showed lower antibacterial activity against S. aureus (4.7 mm and 8.7 mm IZD, respectively) and lower antifungal activity against C. albicans (12.2 mm and 1.7 mm IZD, respectively). At a concentration of 40% thyme extract, the highest antibacterial (23.3 mm IZD) and antifungal (22.5 mm IZD) activities were observed. The GC/MS analysis showed that carvacrol (52.3%), linalool L (16%), and thymol (9.6%) were the main components of thyme extract, while in the rosemary extract β-amyrone (18.0%), verbenone (8.0%), and 1,8-cineole (7.26%) were the major constituents.

Abstract: Jatropha Leaves, Staphylococcus Epidermidis, Staphylococcus Aureus. Jatropha curcas L leaves contain tannins, saponins and flavonoids. According to some studies, tannins, saponins and flavonoids have antibacterial power. Based on these indications, it is important to do research on antibacterial potency of jatropha leaf extract (Jatropha curcas L) against Staphylococcus epidermidis and Staphylococcus aureus bacteria. The aim of this research is to know Antibacterial Activity of Jatropha curcas L Extract on Staphylococcus epidermidis and Staphylococcus aureus". This research. An experimental study by testing the antibacterial activity of leaf extract and jatropha result of maceration, infundation and reflux as measured by Minimal Inhibitory Concentration (KHM) on growth of Staphylococcus epidermidis and Staphylococcus aureus bacteria. From the results of the research, it was found that the extract of the reflux was brownish green and the characteristic of jatropha leaves. The amount of extract produced was 17.03 g, so the yield was 17.03%. Jatropha leaf extract of maceration has no inhibitory power to S. epidermidis in 4 series concentrations starting from 3.125 ppm to 25.000 ppm. Inhibitory zones begin to appear at concentrations of 50,000 ppm and increase at concentrations of 100,000 ppm. The drag zone diameter in the Jatropha curcas extract of the reflux showed the inhibitory power in all series of concentrations. The smallest inhibitory zone was shown at a concentration of 3,125 ppm (9.33 mm) and increased with increasing concentrations. The diameter of the inhibit zone was greatest at 100,000 ppm concentrations of 22.67 mm. Description of inhibitory zone diameter of methanol leaf extract of jatropha result of maceration and reflux to S. epidermidis. The conclusion of this research is extract of reflux result giving bigger resistance than maceration extract to S. epidermidis and S. aureus. Methanol extract of jatropha from the maceration and reflux have strong antibacterial activity against S. epidermidis and S. aureus but still under Klindamycin.

The most common skin disorder is acne (Acne vulgaris) which is a chronic inflammatory disease that occurs in the pilosebaceous unit. Infection can be caused by Propionibacterium acnes and Staphylococcus aureus. Moringa leaves are known to inhibit acne growth. Piper crocatum leaves are also thought to have antibacterial activity. The study aims to determine the effect of the combination of the two extracts in inhibiting the growth of acne-causing bacteria, also tested the gel formula to meet physical and chemical parameters as well as stability to temperature and storage, also to test the acute dermal irritation against rabbit. Each extract with a concentration of 0.3%; 0.6%; 1.25%; 2.5%; 5%; 10%; 20%, incubated then measured the inhibition zone, then determined the minimum inhibition zone concentration of the two extracts to determine the lowest levels of the extracts which still gave antibacterial activity against the tested bacteria by the well diffusion method. The extract combination was formulated in a gel preparation with the excipients Carbopol 940, PG, Phenoxyethanol, TEA, CMC, and Aquadest. Antibacterial activity test for gel preparations used the well method with positive control Medi-Klin® gel. Then the formula evaluation includes physical, chemical, and microbiological evaluations. The results showed that the combination gel form had activity against P. acne and S. aureus at concentrations of 2.5% : 2.5%. The combination gel preparation of the two extracts also has synergistic effect in inhibiting acne bacteria. The formula can meet physical and chemical parameters and is stable to temperature and storage.
