Implementasi Fuzzy Expert System untuk Diagnosis Penyakit Jantung

The aim of this study is to design a Fuzzy ExpertSystem for heart disease diagnosis. The designed system basedon RSUD Dr Saiful Anwar by asked questions of the expert doctor . The system has 15 input fields and oneoutput field. Input fields are chest pain type, blood pressure,cholesterol, resting blood sugar, maximum heart rate, restingelectrocardiography (ECG), exercise, old peak (ST depressioninduced by exercise relative to rest), thallium scan, sex, age,blown, and cough with pleghem.The output field refers to the presence of heart disease in thepatient. It is integer valued from 0 (no presence) to 4(distinguish presence (values 1, 2, 3, 4)). This system usesMamdani inference method. The results obtained fromdesigned system are compared with cheking of the expert docter and observed results of designed system are correctin 70%. The system designed in Java software. The systemcan be viewed as an alternative for existing methods todistinguish of heart disease presence
