Abstract

Fuzzy Logic method is a method that has a meaning or term that can not be clearly defined, which has a range of values from 0 to 1. While the method Dempster-Shafer is one method in the Expert System that has a high accuracy because the logic in accordance with expert thinking. Both methods are combined to create a stress level diagnosis system consisting of 6 levels. This system retrieves data of user input phenomenon in the form of value from 1 to 5, then the value is processed by fuzzyfikasi on Fuzzy Logic Method to get membership value each symptom which then multiplied by expert trust value to get density value. Density values that are combined one-on-one using the Dempster-Shafer method to obtain the results of stress level accuracy. Symptom data used in this study were 19 symptom data consisting of 6 psychological symptoms, 10 physiological symptoms and 3 behavioral symptoms. From the results of the research, obtained the accuracy of the system with experts of 93.33%.
