SISTEM PAKAR MENDIAGNOSA PENYAKIT COVID-19 DENGAN MENGGUNAKAN METODE CERTAINTY FACTOR

Abstract

COVID-19 is an infectious disease caused by a newly discovered type of coronavirus. The WHO (World Health Organization) reported that this virus first appeared on December 31, 2019 and the country that was first confirmed was China, precisely in the city of Wuhan.

Previous research is a science to find comparisons and results to find new inspiration for research. Research methodology is a scientific process or method to obtain data to be used for research purposes. Methodology is also a theoretical analysis of a method or method, research is a systematic investigation to increase a number of knowledge. Based on the results of the CF calculation, the value obtained for the Covid-19 disease from the calculation results above can be seen the level of confidence from the results of the diagnosis of the Covid-19 disease, which is 0.97 x 100%, which is 97% with the results obtained, the system identifies that the patient is Covid-19 negative. Based on the results of the analysis and design that have been achieved, it can be applied to apply an expert system application to diagnose Covid-19 disease, where in this application the user can enter and find out the types of symptoms of the Covid-19 disease that the user has and can find out the right handling solution to help dealing with Covid-19.
