THE EFFICACY OF AN INFUSION OF BINAHONG LEAVES (ANREDERA CORDIFOLIA (TEN.) STEENIS) AGAINST WILD STRAIN BLACK-PIGMENTED BACTERIA
No full textObjective: Black-pigmented bacteria represent one of the most prominent causes of chronic periodontitis. The objective of this study is to investigate the in vitro antibacterial effect of an infusion of binahong leaves (Anredera cordifolia (Ten.) Steenis) against black-pigmented bacteria.Methods: The black-pigmented bacteria were isolated from the periodontal pocket of a patient with chronic periodontitis. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by means of a dilution test using 105 cfu/ml of bacteria cultured on Brucella broth containing blood and kanamycin, which was exposed to a 20%, 30%, 40%, 50%, 65%, 80%, and 95% infusion of binahong leaves and then incubated for 24, 48, and 72 h. In the blank disc diffusion test, a 50%, 65%, 80%, 95%, and 100% infusion was dripped onto a paper disc placed at the center of a Brucella agar bacterial culture and then incubated for 24 h.Results: The MIC and MBC of the binahong leaf infusion were >65% and 80%, respectively, while the antibacterial activity was not correlated with the duration of the exposure to the infusion. The diffusion test showed that an increased concentration of the infusion resulted in an increased diameter of the inhibition zone that ranged from 0.42 mm (50% infusion) to 1.42 mm (100% infusion).Conclusion: Binahong leaves infusion has potential efficacy against black-pigmented bacteria</jats:p

The publication data is from articles, reviews, and English and comes from the Scopus database from 1993 to 2022. The keyword used in the data search is "teacher leadership." The investigation found 753 documents later used as the basis for conducting Bibliometric studies. This Bibliometric analysis method uses Vosviewer software. All data is classified by trend; country; organization; source; author, relationship between authors; and teacher leadership research hotspots which were then analyzed using the Vosviewer software. The main findings of the study include: the trend of teacher leadership publication continues to increase, and the future direction of teacher leadership research will concern two domains, namely: new word/phrase domains connected to teacher leadership, such as COVID, leadership style, self-efficacy, diversity, school principal, evidence, professional learning, community; and domain teacher leadership research processes or methods such as mix-method, instrument, questionnaire, and data processing. The findings of this study can be used as one of the materials for making decisions related to improving teacher leadership publications
