Since long ago Indonesia used nutritious plants as traditional medicines. Various types of plants in Indonesia can be used as alternative ingredients, one of which is aloe vera. Aloe vera contains saponin and anthraquinone, so aloe vera leaves function as antiseptic and antibacteria. Staphylococcus aureus is a gram-positive coccus bacteria. This bacterium is often found as a normal germ flora in humans. Staphylococcus aureus can cause infections in humans and animals. This study aims to determine the effect of ethanolic extract of Aloe vera leaves in inhibiting Staphylococcus aureus by using maceration extract method. The concentrations used were 20%, 40%, 60%, 80% and 100% with positive control (Erytromycin) and negative control (aquades). The inhibitory zone analysis is done using the table method. Test of ethanol extract of Aloe vera leaves in inhibiting Staphylococcus aureus produced inhibition zones at concentrations of 60%, 80% and 100% with average diameter of 6.94 mm, 6.22 mm and 9.5 mm. The conclusion of this research is the ethanolic extract of Aloe vera leaves can inhibit Staphylococcus aureus in high concentrations

Escherichia Coli Bacteria

Diarrhea is caused by bacterial infections, especially Staphylococcus aureus and Escherichia coli. The breadfruit leaves (Artocarpus altilis) are known contain flavonoid compounds, alkaloids, saponins, and tannins which can be used as antibacterial. This research was conducted to determine the ethanol extract of the breadfruit leaves against Staphylococcus aureus and Escherichia coli bacteria. The manufacture of the breadfruit leaf extract was using a maceration method with 96% ethanol solvent. The result of the tube test and the TLC test was positive, the breadfruit leaf extract containing flavonoids and tannins which have potential as antibacterial. The antibacterial test was carried out using the disc diffusion method (Kirby-Bauer test) against Staphylococcus aureus and Escherichia coli bacteria incubated for 1 x 24 hours. The extract concentrations tested were 10%, 15% and 20%. The positive control was using erythromycin antibiotics and the negative control was using aquades. The identification of the chemical content of plants is done by tube test and the TLC test. The results of incubation of the breadfruit leaf extract with concentrations of 10%, 15% and 20% against Staphylococcus aureus bacteria, the average diameter of inhibitory zones respectively were 3.67, 3.50 and 2.67 mm with the positive control diameter of inhibition zone was 18.5 mm, the negative control diameter of inhibition zone was 0 mm. The results of incubation of the breadfruit leaf extract with concentrations of 10%, 15% and 20% against Escherichia coli bacteria, the average diameter of inhibitory zones respectively were 5.33, 3.17 and 3.33 mm with the positive control inhibition zone diameter of 28.5 mm and the negative control of inhibition zone diameter of 0 mm. The activity of ethanol extract of the breadfruit leaves against the Staphylococcus aureus and Escherichia coli bacteria is included in the weak category.

Eye Pain

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.

Garlic (Allium sativum L.) is one of the traditional medicines which has an antibacterial efficacy compound namely Allisin which is able to inhibit the growth of Staphylococcus aureus bacteria. This study aims to formulate the garlic bulb extract into a good gel preparation for use as an acne drug and to determine the antibacterial effectiveness of the ethanol extract of garlic gel against the bacterium Staphylococcus aureus using the wells method. The gel evaluation was carried out to meet the requirements with organoleptic test parameters, homogeneity, pH, spreadability, adhesion and irritation test. This study uses extracts of 10% and 20% concentrations, at each concentration being able to inhibit the growth of Staphylococcus aureus bacteria. In the formula, the concentration of 20% has a inhibition zone diameter of 1.59 cm and a concentration of 10% has a inhibition of 1.50 cm. Statistical test results using the One Way ANOVA test found that there was no significant difference between the average diameter of inhibition of garlic extract gel concentration of 10% with a concentration of 20%.

The nephroprotective prospective of Premna tomentosa extract against Alcohol induced nephrotoxicity in rats was investigated in the present study. The characterization of ethanol extract of Premna tomentosa (EPT) was performed using standard phytochemical analysis. Male albino wistar rats 36 in numbers were divided into 6 groups including control, negative control, positive control and various doses of EPT Treated groups; Nephrotoxicity was induced by alcohol (1ml/100gm b.wt) in animals. Rats intoxicated with Alcohol were fed with 500, 750 mg/kg dose of EPT and Liv 52 (1ml/100gm b.wt) for 60 days. Results show that EPT (500mg/kg b.wt) had a significant effect against alcohol induced nephrotoxicity in rats than EPT (750mg/kg b.wt) in blood parameters and consonantly good histopathological changes in kidney. The deleterious histopathological alterations in kidney associated with glomerular and tubular changes in alcohol intoxicated rats was evident. This result shows Premna tomentosa may be used as supplementary drug for alcoholics.
