Abstract

Guava fruit production often declines due to diseases that are difficult for farmers to recognize early. A lack of knowledge about the visual symptoms of these diseases results in slow and inaccurate identification, hindering effective control efforts. This study aims to develop a disease detection system for guava fruit using a Convolutional Neural Network (CNN) based on the VGG16 architecture, implemented in an Android application. The CNN model is designed to classify four fruit conditions: Healthy, Phytophthora, Scab, and Styler End Rot. The dataset used has undergone preprocessing steps including resizing, data splitting, augmentation, and normalization. The best performing model was obtained using a learning rate of 0.001, the SGD optimizer, and a dropout rate of 0.5. Evaluation results show an accuracy of 90.70%, precision of 90.87%, recall of 90.68%, and an F1-score of 90.68%. The model is deployed using Google Cloud Run and stored in Google Cloud Storage. The developed Android application provides features such as login, image classification, and prediction history. Testing using the Blackbox Testing method indicates that all features function according to the designed specifications.
