Pneumonia is a serious disease and can threaten human life, pneumonia is most serious when it occurs in infants and children. This study was conducted at the Tebat Karai Health Center, Tebat Karai Sub-district, Kepahiang Regency. Given the large number of patients suffering from pneumonia, sometimes the Tebat Karai Health Center has difficulty in handling it. Therefore, an expert system using the Certainty Factor method was designed.
