Abstract: Water sources are often polluted due to human intervention. Water pollution may be classified according to its quality, which is governed by factors such as pH, turbidity, the conductivity of dissolved oxygen (DO), nitrate, temperature, and biological oxygen demand (BOD). This research compares water quality categorization methods that use machine learning techniques, namely SVM, Decision Tree and Naïve Bayes. The characteristics considered to determine the quality of water are: pH, DO, BOD and electrical conductivity. Classification models are formed based on the numerical water quality index (WAWQI). After evaluating the results, With an accuracy of 98.50%, the decision tree approach was determined to be a better categorization model.
Keywords: Classification model; decision tree; support vector machine; naïve bayes; water quality index.
