Abstract

Congestive heart failure or Congestive Heart Failure (CHF) is the number one cause of death in the world. There are approximately 5.7 million adults with heart failure in the United States and 550,000 new cases are diagnosed each year. This has encouraged a lot of research on heart failure, one of which is using the Machine Learning method to predict death from heart failure early. From these problems, the authors will conduct Machine Learning research using two different algorithm models, namely K-Nearest Neighbor (KNN) and Support Vector Machine (SVM). These two models will predict death due to heart failure. The dataset regarding the factors for diagnosing heart failure can be accessed widely and freely on the Kaggle website which is divided into two, namely data training and data testing then analysis and prediction are carried out, so that information is obtained in the form of an accuracy rate in predicting death in heart failure. Using this function also produces the accuracy of each model on the data that has been trained. Data taken were 299 patient data with 13 features or attributes, then divided into 239 training data and 60 test data. The value obtained is an accuracy of 85%. The accuracy obtained is more than 80% of the total data tested so that it can be used or implemented to classify heart failure.

Abstract

This research discusses the design of an expert system that specifically deals with the problem of pulmonary tuberculosis. Tuberculosis or abbreviated TB / TB is an infectious disease infectious disease caused by bacteria from the Mycobacterium group, viz Mycobacterium tuberculosis. According to Infodatin Center for Data and Information Ministry of Health of the Republic of Indonesia (2016) tuberculosis or TB can attacks various organs, especially the lungs, which if not treatment or treatment is not complete then it can cause complications dangerous to death. Seeing the phenomena that occur is very much needed precise and easy information on pulmonary tuberculosis by developing an Artificial Intelligence technology, namely the Expert System. In the application of Expert Systems used to diagnose Pulmonary tuberculosis needs to be compared several methods including: Certantiy Factor, Dempster Shafer, and Bayes theorem so that later it can be known which method most appropriate and best in making a diagnosis. With this Expert System, it can later be used as a consulting service to assist in diagnosing the type of pulmonary tuberculosis based on clinical symptoms that occur in patients, so that it can be used in making initial diagnostic conclusions before carrying out intensive laboratory examinations.
