 Indonesia has been severely affected by the COVID-19 pandemic since its initial outbreak in late 2019. In the past year, the country has seen a dramatic increase in the number of confirmed cases and deaths caused by the virus. To better understand this situation, we analyzed the data from March 2020 to January 2021. We used time series and forecasting methods to predict the number of daily cases and deaths due to COVID-19 in Indonesia. Our results show that the highest monthly average case prediction is in June, with a total of 35,662 cases. Additionally, our model had a MAPE score of 15.85%, indicating that it was able to accurately predict the number of daily cases and deaths due to COVID-19 in Indonesia.
