<![CDATA[Abstract Potato leaf disease is one of the main factors that can reduce crop quality and yield, thus requiring an accurate and efficient identification method. Manual identification is often inconsistent and time-consuming. This study aims to develop a deep learning-based model using the EfficientNetB3 architecture with a transfer learning approach to identify potato leaf diseases. The dataset was obtained from Kaggle, namely the Potato Disease Leaf Dataset (PLD), and processed through preprocessing stages including augmentation and normalization. The model was trained using the Adam optimizer to achieve optimal performance. The evaluation results indicate that the model achieved a test accuracy of 99.50%, with precision of 1.00, recall of 1.00, and F1-score of 1.00. The model was then deployed into a Flutter-based mobile application and demonstrated the ability to accurately identify real-world data.
