Background: SARS-CoV-2 was declared a global pandemic by the World Health Organization in March 2020. Vaccination is an important step to prevent COVID-19. This study aimed to analyze the predictive factors of community engagement in COVID-19 vaccination in East Java, Indonesia. Methods:  A cross-sectional study using purposive sampling was conducted on people aged 12 to >60 years (n=1024) in Lamongan Regency, East Java Province, Indonesia in August-September 2021. The data was collected using a self-administered questionnaire. Logistic regression analysis was used to estimate the relationship between community engagement in COVID-19 vaccination and other predictors. Results: We included 1,024 people aged 12-65 years, with a mean age (±SD) of 29 (12.7). Around 94.0% of the participants reported that they had been vaccinated twice. The role of supportive health cadres could increase community participation by 0.496 times in COVID-19 vaccination compared to the less supportive health cadres (OR= 0.496; 95.0% CI: 0.292-0.845; P=0.010). In addition, the role of supportive community leaders could increase community participation by 1,959 times in COVID-19 vaccination compared to the less supportive community leaders (OR= 1.959; 95.0% CI: 1.080-3.551; P=0.027). Conclusion: The role of health cadres and community leaders can increase community participation in COVID-19 vaccination. The partnership between community health center and community engagement in the COVID-19 vaccination program needs to be continued.

This study investigated the types of vocabulary learning strategies (VLS) employed by Indonesian college students. The study specifically aimed to find out (a) the most and the least frequently used VLS, and (b) the most useful VLS. A total of 105 nursing students who attended a virtual exchange program during the odd semester of 2021/2022 academic year participated in this study. This was ex post facto research which used a vocabulary learning strategy questionnaire to collect the data. To answer research questions, the collected data were analyzed by using SPSS statistics 25.0, including the descriptive statistics. The overall findings revealed that in terms of five categories, determination strategies were reported to be the most frequently used strategies and social strategies were the least ones. In terms of individual strategies, the most frequently used vocabulary learning strategies were ‘using bilingual dictionaries either print or electronic’, ‘guessing word meaning through the context’, and ‘learning new vocabulary items through vocabulary videos”. The least frequent ones were ‘asking the word’s synonym to the teacher’ and ‘communicating with native speakers. Furthermore, the participants assumed that ‘using bilingual dictionaries either print or electronic’ and ‘taking notes of new words’ as the most useful strategies. Considering the results, both students and lecturers must be more aware of the effective learning strategies to achieve better results
