Tobacco is one of the largest agricultural products and is widely traded in the world market, including in Indonesia. In Indonesia, tobacco leaves are used as raw material for cigarettes which are mostly produced by cigarette companies. The quality of tobacco leaves greatly affects the quality of cigarettes, this is because the condition of tobacco leaves is influenced by several factors including pests, diseases, and climate. This study uses the Gray Level Co-Occurrence Matrix (GLCM) method for texture feature extraction, while for classification uses the K-Nearest Neighbor (KNN) method to classify the quality of tobacco leaves. The data used in this study is the image of tobacco leaves taken directly in TonDowulan Village, Plandaan District, Jombang Regency at the age of the leaves of approximately 2 months. Tobacco leaf images used were 300 images consisting of 3 classes, namely Normal, Perforated, and Withered based on the level of leaf damage. The GLCM features used are Contrast, Correlation, Energy, Homogeneity, and Entropy which will then be classified using the KNN method where before performing feature extraction the data must be processed first at the preprocessing stage. The result of the training using GLCM and K-NN feature extraction produces the highest accuracy value when the neighbor value 1, pixel distance 3, and k-fold 2 are 83.33%.
