Knowledge, attitudes, and behaviour of college students in disposing used masks during the COVID-19 pandemic in DKI Jakarta Province.

Background: The COVID-19 pandemic has increased the need for mask production which has caused the problem of mask waste generating in the environment without being managed. This research was conducted to determine the relationship between knowledge, attitudes, and sociodemographic factors with college student behaviours in managing household mask waste in Daerah Khusus Ibukota (DKI) Jakarta Province. Methods: This study used a quantitative approach and cross-sectional study design. Data collection was carried out using an online questionnaire consisting of the respondents' sociodemographic, knowledge, attitudes, and behaviours. Results: The majority of students had high knowledge (63.3%), positive attitudes (52.5%), and good behaviours (50.6%). Statistically, there was a significant relationship between knowledge and behaviours (p = 0.022), but there was no significant relationship between attitudes and behaviours (p = 0.269). In addition, the sociodemographic factor variables showed a significant relationship between place of residence and behaviours (p = 0.008). However, there was no significant relationship between age, gender, education, and study program groups and behaviours (p > 0.05). Multivariate analysis showed that living with family was a dominant factor for bad behaviours (OR 1.664, 95% CI=1.124-2.464), and the second risk factor was the low level of knowledge has a significant relationship with the behaviours of mask waste management at home (OR=1.559, 95% CI=1.044-2.330). Conclusions: Students who live alone also show better behaviour compared to students who live with their families. The place of residence variable has the greatest influence on the behaviour of mask waste management at the household, followed by the knowledge variable.

Bacteria contamination analysis on the hands and bowls of meatball cart vendors: an observational descriptive study.

OBJECTIVE: To describe the presence of bacteria at the seller's hand of meatball vendors and cart meatball bowls. METHOD: This is a descriptive study with an observational approach. Thirty mobile meatball vendors were recruited as participants. Therefore, the bacterias from bowls and hands were taken by swab sampling. The number of bacterias were obtained using total plate count method by means of nutrient agar. Bacteria types were identified using Gram staining method and bacteria assay. RESULTS: The hands and bowls swab samples were positive for Gram-positive and Gram-negative bacteria in all cases. These microorganisms include Acinetobacter calcoaceticus, Klebsiella sp., Alcaligenes faecalis, Enterobacter aglomereus, Pseudomonas aeruginosa, Enterobacter aerogenes, Enterobacter cloacae, and Staphylococcus saprophyticus, Serratia rubidaea, Yersinia enterocolitica, E. aerogenes, and Staphylococcus epidermidis. CONCLUSIONS: Some types of bacterias were present in cart meatball bowls and the sellers' hands. This phenomenon is affiliated with the emergence of food-borne diseases for the consumers.
