Design and Development of Fuzzy Logic Application Mamdani Method in Predicting The Number of Covid-19 Positive Cases in West Java

Abstract

The increase in covid-19 positive patients is unpredictable which results in being unprepared in dealing with Covid-19 cases. People in monitoring and patients under supervision are the category that is breastfeed to be covid-19 positive patients after passing the incubation period for 14 days. Artificial intelligence used to predict the increase in cases of covid-19 positive patients is fuzzy logic. The fuzzy logic method used in this study is the mamdani method. The enter variables used are the increase in ODP, PDP, and Covid-19 positive with 3 sets of low, medium, and high respectively. While the output variable is a positive prediction 14 days later. The curve used for fuzzification needs is a linear curve. The method of composition of the rules used is the MAX function and defuzzification using Centroid.
