Propionibacterium acnes is one of the causes of acne. Shallot peels contain flavonoids, tannins, and saponins which potentially have antibacterial activity. The purpose of this study was to determine whether the water extracts of shallot peels have antibacterial activity against Propionibacterium acnes and determine the concentration which can inhibit the growth of bacteria Propionibacterium acnes. This research is an experimental study. The research stage begins with the extraction of shallot peels using in the foundation. Antibacterial activity was tested using the diffusion method with the Cup-plate technique. Propionibacterium acnes used as a sample of bacteria, with extract concentrations of 5%, 10%, 20%, and 40%. Positive controls used are clindamycin 150 mg and negative controls were used dimethyl sulfoxide 1% (v / v). Data were analyzed with a statistical test of the Kolmogorov-Smirnov method. The measurement results inhibition zone of shallot peels water extract with a concentration of 5%, 10%, 20%, and 40% of the bacteria Propionibacterium acnes sequentially by 12.8 mm, 13 mm, 14.33 mm and 15.50 mm in the strong category. The measurements of bacterial growth inhibition zone were statistically analyzed with the Kruskal-Wallis method gained 0,053 results indicating that the test has a significant effect (P > 0.05) with a decision that means that there is no significant difference between all concentrations.

Genus Mentha presents group of plants which are the most studied in family Lamiaceae. Aboveground parts are used for different purposes in pharmacy, food industry or confectionery. Most important is natural product extracted from leaves - essential oil (EO). The aim of presented experiment was to demonstrate different chemotype and compare antibacterial activity of two Mentha species EO. Plant samples were obtained from various environments – from Slovakia and from Italy. Dominant compounds were determined by GC/MS. The results showed high amount of menthol and menthone in tested Slovak peppermint EO. On the other hand, carvone and 1,8-cineole were determinate as dominant compounds in Italian spearmint EO. The antimicrobial activity of the EO was investigated by disc diffusion and broth micro dilution methods. EO was evaluated for their antibacterial activity against 7 microorganisms: Enterobacter cloacae, Salmonella spp., Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Streptococcus pyogenes. The determination results of antibacterial activity by agar disk diffusion method ranged from 7 to 14 mm of the growth inhibition zone. MIC of tested mint EO varied from 0.625 to 2.5 μg/mL. In addition, both EO showed relatively the same antibacterial activity against the selected Gram-negative bacteria. However, there is a variation in the antibacterial activity against Gram-positive bacteria.

For each solvent, 0.2 μl Kaempferia galanga extractdroped into 6 mm steril paper dics. 0.1 ml Lactobacillus acidophilus inoculated on MRS agar. Each disc contains extract were impragnated into the agar media, then incubated at 370C for 24 hours, and inhibition zone measured.Results: Mean scores of Kaempferia galanga extract in 3 different solvents are: Kaempferia galanga (dichlormethane) is 1.6400; Kaempferia galanga (ethanol) is 1.7440; Kaempferia galanga extract is 1.6600; boiled Kaempferia galanga is 1.7000. Using Mann-Whitney Test, the results are: negative controls have no inhibition effect on Lactobacillus acidophilus compaired to Kaempferia galanga extract, comparation of those 4 Kaempferia galangal treatments shows no significant difference, those 4 Kaempferia galanga treatments compaired to erythromycin antibacterial effect shows significant difference, otherwise 4 Kaempferia galanga treatments compaired to penicillin shows no significant difference except Kaempferia galanga (ethanol).Conclusions: Kaempferia galanga extract can kill Lactobacillus acidophilus. Inhibition effect of Kaempferia galanga extract has no significant difference to penicillin but lower inhibition effect than erythromycin. The Kaempferia galanga extracts showed better antibacterial activity than penicillin.

The objective of the study was to know the antibacterial activity of ethanol extract of Gamal leaf (<em>Gliricidia sepium</em>) for <em>Streptococcus mutans</em> in various concentrations. This study was a true experimental with post-test only control design. The determination of antibacterial activity in this study was conducted by using Kirby Bauer disk diffusion method with the various concentrations, there were 40, 50, 60, 70 and 80%. The positive and negative controls in this study were 30 µg disk diffusion of chloramphenicol and the 96% of ethanol. The average inhibition of zone diameter in the concentrations of 40, 50, 60, 70 and 80% were 11.3, 12.3, 13.4, 15.3 and 19.2 mm, respectively. One Way ANOVA statistical analysis showed that the value of p was 0.000, so there was a difference of growth inhibition zone of <em>Streptococcus mutans</em> in various concentrations of ethanol extract of Gamal leaf (<em>Gliricidia sepium</em>). Based on the result, it can be concluded that the ethanol extract of Gamal leaf (<em>Gliricidia sepium</em>) have strong antibacterial activity, especially to <em>Streptococcus mutans</em> bacteria.</p>

Diarrhea is still one of the world’s major health problem especially in developing country. Foods and beverages contaminated by microorganism become the risk factor of diarrhea, including Escherichia coli (E. coli). One of the curative effort that can be done is to utilise the secondary metabolite compounds contained in binahong leaf (Anredera cordifolia (Ten.) Steenis). This study used true experimental method. The sample was binahong leaf extract with concentration of 25%, 50, and 75% using diffusion method (Kirby-Bauer) on doublelayered Mueller Hinton Agar (MHA) (base layer and seed layer) in order to measure the growth inhibition zone around the cylinder plate. The amount of population on this study was 24 isolations of E. coli. The repetition of each treatment group was counted by Federer formula. The result analyzed using Kruskal-Wallis test and showed that there was difference on binahong leaf extract effectiveness (p < 0,05), as well as on post hoc analysis using MannWhitney test showed that there was significant difference at concentration of 25%,50%, and 75%. (p < 0,001). This shows that there is a significant differences in the concentration of binahong leaf extract.

ABSTRACTBackground: Infectious diseases are one of the major causes of death worldwide, mostly caused by bacteria. The use of less targeted antibiotics leads to resistance cases, thus encouraging the discovery of  alternative  medicine.In  general,  gedy  leaves  are  known  as  animal  feed  but gedy  leaves  contain antibacterials such as flavonoids, saponins, tannins and terpenoids. Research Purpose:This study aims to determine the antibacterial activity of ethanol extract of gedy leaves on the growth of E. coli and S. aureus. Research Method: This research uses post test only control design, free variable is ethanol extract of gedi leaves and dependent variable is bacterial growth inhibition zone. Ginger leaf ethanol extract was obtained by maceration method for 3 x 24 hours. The test of antibacterial activity using the well diffusion method. Research result: The results of ethanol extract of gedi leaf with concentration of 2.5 mg/ml, 1.25 mg/ml and 0.625 mg/ml resulted in inhibition zone to E. coli growth successively; they were 11.33 mm, 8 mm and 6.3 mm. Extracts of the same concentration also showed inhibition of S. aureus growth with inhibit zone of 8 mm, 3.6 mm and 2 mm. Conclution:The conclusion of this research is the extract ethanol of gedi leaf has antibacterial activity against E. coli and S. aureus.Keywords: Antibacterial,E. coli and S. aureus , Gedi leaf (Abelmoschus manihot L.), Infection.
