Design of Expert System Diarrhea for Toddler Using K-Nearest Neighbor Algorithm (K-NN)

Abstract

Diarrhea is one of the main causes of death in children under the age of 5 years. Based on reports from the World Health Organization (WHO), 1 in 10 children died of diarrhea with 800,000 deaths per child. When toddlers suffer from diarrhea there are obstacles faced by parents when having to consult a pediatrician, for that we need a system that can store the expertise of an expert in this case a pediatrician in dealing with diarrheal diseases that occur in infants. The K-NN (K-Nearest Neighbor) algorithm was developed in this research expert system. The variables used were 14 symptoms where diarrheal diseases were classified into 6 types. The results of distance calculation show testing data (new cases) No RM 4247 approaching 3 training data (old cases) with a distance value of 2.24. The addition of the calculation of similarity in the calculation strengthens the results of the diagnosis, with the largest similarity value of 79% at No RM 1090, then the testing data (new cases) didignosis mild acute dehydration diarrhea.

“…An expert system is a computer program that contains the knowledge of one or more human experts in a specific area [4]. Many areas can be addressed by expert systems, including diagnosis of plant diseases and pests [5], pharmacy live plants for alternative medicine [6], dental disease expert systems [7], diseases digestive systems [8], education, machine tools [9], damage to vehicles such as cars [10], diagnostics of damage to other vehicles, including airplanes [11], etc. Several previous studies on expert systems that can help diagnose aircraft damage include a Landing Gear Damage Identification System on Cessna aircraft [12], an expert system for diagnosing damage on a Cessna Grand Caravan 208B [13], an equipment detection system used to assist work activity activities at airports that are often damaged due to the way the operator uses equipment that is not suitable [14].…”
