Policy effectiveness analysis using system dynamics based on the threat of Covid-19 in Sukoharjo Regency, Indonesia.

This research was conducted to assess the effectiveness of the policy with System Dynamics based on the threat of the COVID-19 hazard in Sukoharjo Regency. This research employs a stock-flow diagram approach, which is a component of system dynamics. Data collection is done by documentation techniques. The COVID-19 hazard assessment uses indicators in the form of crowd points, settlement density, and the number of cases considering that the research area is one of the growth areas of Surakarta City. The stock-flow diagram approach is used to assess the effectiveness of the policy by modeling several policy scenarios such as implementing vaccines, quarantine, providing care, health protocols, or disaster risk reduction habits combined with the COVID-19 hazard factors in areas with a high threat classification. The results revealed that the Kartasura District, Grogol District, and Mojolaban District have significant COVID-19 threats. The hazard factor for COVID-19 in Sukoharjo Regency is the density of settlements, roads, and the centers of crowds in the area, considering that these three areas are close to Surakarta City. The result showed that the implementation of quarantine and vaccination can have a positive effect on slowing the spread of COVID-19. The implementation of quarantine can have a positive effect on slowing the spread of COVID-19 with community participation in the Jogo Tonggo Movement, thus forming a community survival strategy in dealing with the COVID-19 pandemic. This model produces insights for policy solutions to decrease viral propagation in places with a high COVID-19 threat. [ABSTRACT FROM AUTHOR]
