Knowledge Level of COVID-19 Prevention in Banjar Gambang Communities, Seraya Village, Karangasem, Indonesia

Background: Problems to COVID-19 are closely related to the level of knowledge and community prevention. Therefore, to overcome COVID-19, increased knowledge and prevention are needed. This study aimed to evaluate the correlation between prevention and knowledge level about COVID-19.Methods: A cross-sectional study using a convenience sampling approach was conducted in Banjar Gambang, Karangasem, Indonesia, in April 2022. The knowledge level and preventive behavior towards COVID-19 were measured using the COVID-19 Preventive Behaviors Index (CPBI) and the knowledge, attitudes, and practice toward COVID-19 (KAPCOV-19) questionnaire. The data were analyzed using SPSS software version 26.0.Results: A total of 52 respondents were included, who had excellent level of knowledge (44.2%) and moderate prevention behaviour (48.1%). A strong and significant correlation was found between the preventive index and the knowledge levels of COVID-19 (r = 0.548; p<0.001). The level of knowledge was significantly related to the level of preventive behavior (p= 0.003), as well as the education level (r = 0.323; p = 0.02) and age (r= -0.346; p=0.012).Conclusion: The level of knowledge and the individual prevention behavior toward COVID-19 are directly proportional to each other. Those who have a low level of knowledge, might affect their prevention behavior toward COVID-19, therefore, personalized socialization of COVID-19 prevention is still required

Analysis of Antiquorum-Sensing and Antibiofilm Activity by Pomelo Peel Extract (Citrus maxima) on Multidrug-ResistancePomelo Peel Extract (Citrus maxima) on Multidrug-Resistance Pseudomonas aeruginosaPseudomonas aeruginosa

Pseudomonas aeruginosa is gram-negative bacteria with high adaptability by forming biofilms and quorum-sensing mechanisms to avoid immune responses and antimicrobial agents which tend to develop into Multidrug Resistance (MDR) related to Healthcare-Associated Infection (HAI) with a prevalence of 3,8% in Indonesia and a mortality of up to 69%. Polyphenol compounds found in pomelo peels (Citrus maxima) have been shown to have antibiofilm and anti-quorum-sensing effects but are less investigated. Therefore, this study aimed to investigate those effects on MDR P. aeruginosa. In vitro study design is performed to evaluate the inhibition effect of ethanolic extract on bacterial growth (Kirby-Bauer test), biofilm formation (biofilm assay), and quorum-sensing activity (pyocyanin and pyoverdine assay) on clinical isolates of MDR and ATCC strain as comparator. Furthermore, we employed computational methods using docking protein analysis. Biofilm formation was significantly inhibited by 71.1% ± 4.4% in MDR (pLasR and LasI ) by active compounds of Citrus maxima. Molecular docking was used to further strengthen this hypothesis, showing no significant differences in bonding energy of polyphenol compounds found in pomelo peel with LasR and LasI compared to the native ligand and inhibitors. Pomelo peel extract can be considered as a potential therapy for MDR P. aeruginosa infection mediated based on its antibiofilm and antiquorum-sensing effects
