“…Luteolin's ability to block DNA topoisomerase I and II activity, which led to a reduction in the production of nucleic acids and proteins, is what gives it its antibacterial properties (20). An important flavonoid compound, called quercetin has a wide range of medicinal effects.…”

Streptococcus mutans and Candida albicans are the main microorganisms that cause dental cavities. It can cause infection, damaged tissue around teeth, abscesses, and focal infection to other organs in the body. Natural products are currently widely used as products or as additives in the prevention of dental caries which have more anti-bacterial and anti-fungal activities than antibiotics that can cause resistance. Citronella (Cymbopogon citratus) is abundant and easy to grow. This study was conducted to determine the effectiveness of citronella (Cymbopogon citratus) oil on the growth of S. mutans and C. albicans microorganisms by Minimum Inhibitory Content (MIC) and Minimum Bactericidal Content (MBC). The method of MIC is broth microdilution by making chlorhexidine concentration levels of 100%, 50%, 25%, 12.5%, 6.25%, 3.125%, and 0.2% with 4 replications each. The MIC value was determined based on absorbance spectrophotometry and the MBC value was determined from the agar plate using the spread method. Biofilm eradication test was conducted by crystal-violet staining and measuring the absorbance. The results of MIC and MBC were obtained on S. mutans, namely at concentrations of 25% and 100%, respectively. Meanwhile, the results of MIC and MBC on C. albicans were obtained at concentrations of 50% and 100%, respectively. Furthermore, the citronella oil has antibacterial and antifungal activities.

The number of Covid-19 patients hospitalized continues to increase in line with the increase in Covid-19 cases in Indonesia. The increasing number of Covid-19 patients in hospitals is increasing the workload of paramedics. High workloads will cause saturation and fatigue. In addition, an increase in the number of Covid-19 patients increases anxiety and depression will be infected when treating patients. Paramedics should also use personal protective equipment during shift guards which causes dehydration and discomfort. This situation can degrade the quality of service to patients. The study aims to measure the mental workload of paramedics by NASA-TLX (National Aeronautics and Space Administration Task Load Index) method and find out the factors that affect mental workload levels. This research is a quantitative research with a cross sectional approach. The research was conducted at Hospital X type C in Malang Regency in October 2020. The samples used were all 100 Hospital X paramedics. Research instruments in the form of questionnaires shared through Google Form. Data analysis is done with descriptive analysis and Chi-Square analysis with p value <0.05. The results found paramedics had a low mental workload of 1%, a moderate mental load of 3%, a high mental workload of 47%, and a very high mental workload of 49%. The Chi-Square test results found that age factors had an effect on the mental workload level of paramedics.
