On establish the relative impact of the model parameters to disease transmission, a sensitivity analysis of the epidemiological model is undertaken. A sensitivity analysis of the Susceptible, Exposed, Infectious, and Recovered (SEIR) model of corona virus 2019 (COVID 19) was undertaken to determine the parameters’ influence on the basic reproduction number and endemic equilibrium. The rate of contact between susceptible individual and exposed individuals and rate of exposed to infected individuals are the most impactful parameters on the basic reproduction number and the number of infectious individuals, according to our findings. Furthermore, the number of people who have been exposed is affected by the rate at which they proceed from exposed to infect. The findings show that if infect...

We validate them by the use of the Maximum Principle. The findings revealed that the best practice of combining all three intervention measures considerably reduces the proportion of people who are exposed and symptomatic, as well as those who are asymptomatic.

This research is a type of Research and Development (RD) research with the ADDIE model which includes five steps including: analysis, design, development, implementation, evaluation. The subjects in this study were media expert validators, education practitioners, material experts, namely fifth grade teachers and fifth grade elementary school students. The research instruments used in data collection were questionnaires, observation, and documentation. The results of this study indicate that Powtoon learning media in Thematic Learning Theme 2 Clean Air for Health Class V SD "Very Eligible" with details of the eligibility percentage given by Media Experts in sub-theme 1 of 71.6% in the "Decent" category, media sub-theme 2 86.6% in the "...

However, when monitoring, students were still found cheating. If this reality always occurred, then the degradation of students' competence and character cannot be avoided. Based on the phenomenon found, then it should be solved by implementing scientific-based learning activities through classroom management techniques. Learning activities are the involvement of students in terms of attitudes, thoughts, attention to observing, questioning, acting, reasoning and communicating so that optimal learning conditions are created and maintained, then an atmosphere of learning is conducive and interactive in a classroom management system called face-to-face arrangement. . After the learning activity, an exam is carried out as an effort to overcome the habit of cheating by applying soundproof techniques. During the exam, the situation was conduci...

Data were obtained through tests of mathematical reasoning abilities consisting of students 'pre-test and post-test as well as a questionnaire to see students' self-confidence. Data were analyzed by independent test T-Test N-Gain Score. Based on the results of the independent T-Test N-Gain test scores of students' mathematical reasoning abilities obtained a significance value = 0.008 because of the sig level. smaller than 0.05, so it is concluded that there is a difference in the increase in students' mathematical reasoning abilities with a metacognitive approach higher than the realistic mathematics approach. Furthermore, for self-confidence, the significance value = 0.000 because of the sig level. smaller than 0.05, it is concluded that there is a difference in the increase in students' self-confidence with a metacognitive approach higher than the realistic mathematics approach. Furthermore, for the research results, the difference in the increase in students' mathematical reasoning and self-confidence in terms of the indicators is that there is a significant difference in the increase in mathematical reasoning abilities in indicator 1 and indicator 2 which are taught with a metacognitive approach which is higher than students who are taught with a realistic mathematics approach and for indicators 3 and 4. there is no significant difference in the increase in mathematical reasoning abilities. For self-confidence, there is no significant difference in the increase in mathematical reasoning skills in indicator 1 and indicator 2 who are taught with a metacognitive approach and students who are taught with a realistic mathematics approach and there is a significant difference in the increase in self-confidence in indicator 3, indicator 4, and indicator 5 who are taught with the metacognitive approach is better than students who are taught with a realistic mathematics approach.
