In January, WHO declared the Coronavirus Disease (COVID-19) outbreak as a global pandemic. The easy spread of this virus through contact with infected sufferers is a concern. The COVID-19 pandemic should not be taken lightly, like the Iceberg phenomenon, we do not know for sure the factors that affect the level of exposure. Meanwhile, this pandemic has an impact not only on health but also on the economy, society, culture, and psychology. This paper aims to make modelling using a systems thinking approach with the system dynamics method in DKI Jakarta. This model focuses on the conditions during the "homecoming"before Eid, during Eid, and after Eid (when a back flow that occurs). Simulation results show that the flow of homecoming before and during Eid causes positive case behavior is slightly less than without flow, but the flow of homecoming with a back flow that goes out and into DKI Jakarta will cause a second wave of COVID-19 cases. © Published under licence by IOP Publishing Ltd.
