Abstract

SARS-CoV-2 is the virus that causes COVID-19. In Indonesia, the highest number of COVID-19 cases is in the Jakarta province. It is necessary to restrict the virus's transmission. This research purposes to determine optimal control strategies (self-prevention, vaccination, and cure) of the SEAIQHRD model to reduce disease spread. Optimal control analysis is solved utilising Pontryagin's Minimum Principle. In this study, numerical simulations were conducted using COVID-19 outbreak data from Jakarta province from March 1 to August 31, 2022. Based on the analysis results, the basic reproduction number ℜ0 = 2,1316. Since ℜ0 > 1 at the EE point, the COVID-19 spread model is asymptotically stable, indicating that the virus persists in the population. The application of control steps combining all three strategies was shown to reduce the subpopulations of exposed, infected, hospitalized, and deceased individuals. Simultaneous optimal control is more effective at controlling the spread than using a control step. The simultaneous implementation of optimal controls has proven an effective strategy for reducing COVID-19 transmission in Jakarta.

Abstract

The development of the digital era among elementary school children presents challenges in the form of high use of gadgets for entertainment, a lack of understanding of healthy lifestyles, and the suboptimal use of technology as a learning tool at MI Al Munawar, Kepuh Village, Cirebon Regency. This community service activity aims to improve students' understanding of healthy lifestyles, basic science literacy, and the positive use of digital technology. The implementation method is carried out systematically and participatively through five stages: activity socialization; training and interactive education with simple experimental practices; the application of educational digital media; evaluation through pre-tests and post-tests; and mentoring to sustain the activity. The activity results showed an increase in understanding among 40 students across all assessment indicators. The highest increase occurred in the aspect of the use of educational digital technology at 51%. This activity shows that an interactive educational approach based on direct practice and digital media is very effective in shifting the function of gadgets from a means of entertainment to a productive learning medium. This activity is able to encourage the creation of clean and healthy living behaviors, as well as improve the scientific literacy of elementary school students in a sustainable manner
