Abstract :
The use of computer technology in the health sector is
growing rapidly. One of them is by developing an expert system
that is used for early diagnosis of a disease. In this study, we

according to the symptoms experienced to make the right
hypothesis. From the background described, it can be
considered as a research title "Implementation of the Certainty
