		abstract={The protracted COVID-19 pandemic has made the number of positive
cases in Indonesia higher, many Indonesians have been exposed. The spread of
COVID-19 is very fast with various variants continuing to mutate so that the
death toll continues to grow. Many people do not have severe symptoms, so it is
possible for them not to know that they are OTG (Asymptomatic People). This
ignorance is fatal if the person continues to do activities and meets other people,
this will certainly make other people who meet OTG have the opportunity to be
exposed to the virus as well. With the problems that have been described, an
expert system with the Certainty Factor method is needed so that the public can
check yourself whether you have been exposed to COVID-19 or not. The results
of this study have an accuracy rate of 90% of the 30 test data carried out.}
