BACKGROUND: The presence of a coronavirus disease 2019 (COVID-19) vaccine is very important to produce an immune response that slows down the pandemic. AIM: This study aims to find out more about the perspective of the Indonesian people which is predicted to affect vaccine acceptance by the public. METHODS: Quantitative research was conducted using an online survey via a Google form. The survey was conducted from January to February 2021. RESULTS: There were 225 respondents. The attitude of the community towards the COVID-19 vaccination program, almost all respondents know the free vaccination program (94.4%) and know the purpose of the program (91.8%). There were 23% of respondents who felt that after being vaccinated they would be free from COVID-19 infection and 2.4% stated that they no longer needed to apply health protocols after being vaccinated. There were 8.2% who did not agree with the reasons they did not know its effectiveness, were worried about the side effects and were unsure about the safety of the COVID-19 vaccine. CONCLUSION: In general, self-confidence, comfort, calculation of benefits versus disadvantages, and shared responsibility, influence a person’s decision to refuse or accept the vaccine.
The bacteria Staphylococcus aureus are round bacteria that are shaped like a cocci, and are Gram-positive. These bacteria can be found on the skin, genitals, nasal cavity, mouth and around the anus. One of the pharmaceutical products that can maintain skin health and protect the skin is soap. The leaves of noni (M. citrifolia L.) contain various compounds such as flavonoids, tannins, saponins, alkaloids, and triterpenoids which are capable of being antibacterial. This study aims to make a liquid soap formulation from M. citrifolia L. leaf extract and its activity as an antibacterial to S aureus. The leaves of M. citrifolia L. were extracted using 96% ethanol solvent by maceration method until a thick extract was obtained. Soap formulations are made with a concentration of 20% 40% and 60%. Evaluation of soap quality includes organoleptic test, high foam test and pH test. The method of antibacterial testing is carried out in vitro by means of well diffusion. The results on the quality test of the liquid soap formulation showed that the pH and height of the foam had good results and had met the SNI 1996 Standards. From the results showed that formulation III with an extract content of 60% had a large antimicrobial activity with a value of 16.83 mm which was categorized as strong. In positive control (Dettol) 60% antimicrobial activity showed a value of 14.83 mm. The results of statistical tests were carried out by One-Way ANOVA analysis followed by LSD analysis Post hoc, liquid soap extract of M. citrifolia L. had greater antimicrobial potential than the positive control (Dettol).
Antioxidants are chemical compounds that donate one or more electrons to free radicals to inhibit free radical reactions. One of the potential antioxidant sources is gandaria fruit (Bouea Macrophylla Griff). This research aims to determine the antioxidant activity and vitamin C content of the gandaria fruit extract. Gandaria fruit was macerated with ethanol as a solvent. Furthermore, the rotated extract was carried out for the phytochemical screening. The results of the phytochemical screening of the gandaria fruit extract showed a positive of flavonoids, terpenoids, tannins, saponins, and phenolics. The gandaria fruit extract was tested for antioxidants and quantitative analysis of vitamin C levels to obtain IC50 values and vitamin C levels using spectrophotometry UV-Vis at a wavelength of 517nm with vitamin C as a positive control. The results of spectrophotometric measurements revealed that the gandaria fruit extract had an IC50 value of 5.72 g/ml, and vitamin C had an IC50 value of 2.260 g/ml, indicating that the gandaria fruit extract and vitamin C had very strong antioxidants. The value of vitamin C levels was 0.526 mg.
The bacteria that cause infections that can lead to high morbidity and mortality, the bacterium Pseudomonas aeruginosa. Bangle has a pharmacological activity as antibacterial, laxative, pancreatic lipase inhibitor, and protect cells from damage caused by oxidative stress. The purpose of this study are: to know the chemical constituents present in the extract of leaves bangle (Zingiber purpureum Roxb.) Can be efficacious as an antibacterial and knowing Minimal Inhibitory concentration (MIC) of the extracts of leaves bangle against Pseudomonas aeruginosa. Tests on the leaf extracts for antibacterial activity against Pseudomonas aeruginosa bangle made by the method of Kirby Bauer and solvents used are DMSO. Test solution with a concentration of leaf extract bangle 200, 400, 600, 800 and 1,000 ppm, the positive control solution (ciprofoxacin) and the solution negative control (DMSO). The results showed that the chemical constituents present in the extract of leaves bangle (Zingiber purpureum Roxb.) Are flavonoids, saponins, tannins, alkaloids and steroids. Value Minimum Inhibitory Concentration (MIC) of ethanol extract of the leaf bangle S bacteria Pseudomonas aeruginosa is a concentration of 40 % with an average diameter of 5.44 mm inhibitory. MIC extract ethanol extract of leaf bangle belonging to the bacterial activity that is strong enough..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
