SEIR Model Analysis for The Spread of Covid-19 Disease Post New Normal Using Euler Method and Matlab-Assisted Heun Method

Abstract

In early 2020 Corona Virus Disease 2019 (COVID-19) was declared by WHO as a pandemic and the Government of Indonesia based on Presidential Decree Number 11 of 2020 concerning the Determination of Public Health Emergency of Corona Virus Disease 2019 (COVID-19). On this basis, this study aims to find out the solution to the numerical solution of the SEIR epidemic on the rate of Coronavirus Disease (COVID-19) by using the Euler method and the Heun method and to find out the design of a mathematics lesson plan in high school that is in accordance with the concept of the numerical method. In analyzing the spread of the Covid-19 disease after the new normal, a mathematical model of the Covid-19 disease was developed using the SEIR type with the stages of Literature Study, Mathematical Modeling, Model Analysis, Simulation and Drawing conclusions. The target to be achieved in this research is to produce mathematical modeling from the results of the analysis that carried out, reports can be confirmed and report results can be published in international journals. This research will produce TKT types of social humanities and education with the results of the status of R&D results are important and significant for supporting decisions and policies.
