摘要：The purpose of this paper is to predict the final size of the COVID-19 in West Java Province, Indonesia. This paper describes the mathematical modeling and dynamics of a COVID-19 by using the SIR epidemic model. To predict the final size of the positive cases of COVID-19 that occur, the minimum function of the final number of susceptible andrecovered is performed. The numerical simulation was performed with data after West Java Governmentimplemented Large-Scale Social Restrictions. Based on the numerical results is founded the final size of the COVID-19 in West Java Province is 22743 people. This number might have been greater if the Government did not carry out Large-Scale Social Restrictions.
