Abstract

An important factor that influences the price of coffee bean commodities is their quality. Specialty coffee beans are the quality of coffee beans with the highest price. Determining the quality of specialty coffee beans is determined through a long and complicated series of physical tests and cupping test by an expert called Qgrader. This research proposes classifying specialty coffee beans using several machine learning methods. The first step taken was to label the data in accordance with the Specialty Coffee Association of America standard rules. The coffee classes used in this research are Grade 1, Grade 2 and Grade 3. Next, feature selection was carried out using correlation analysis and important features which resulted in 6 features out of 11 features. This study compares the results of classification using 3 different models, namely Support Vector Machine (SVM), K-Nearest Neighbor (KNN) and Random Forest (RF) with accuracy results of 78%, 100% and 100% respectively.
