Abstract- Grapevine diseases often pose a major challenge, leading to reduced crop quality and yield if not detected early. Manual disease identification typically requires specialized expertise, high precision, and considerable time. This study aims to develop an automated deep learning-based classification model for grapevine leaf diseases using the Convolutional Neural Network (CNN) method with a DenseNet121 base architecture. The dataset consists of 1,600 digital images of green grapevine leaves (*Vitis vinifera* L. var. Thompson Seedless) collected from plantations in Sukaraja District, Bogor Regency. These images are evenly distributed across four condition classes: Healthy, Black Measles (Esca), Leaf Blight (Isariopsis Leaf Spot), and Black Rot. Model testing was conducted using two data split scenarios: 80:10:10 and 70:15:15. The results demonstrate that the DenseNet121 architecture effectively extracts visual image characteristics. The best performance was achieved with the 70:15:15 data split, yielding a validation accuracy of 91.25%, whereas the 80:10:10 split resulted in an accuracy of 88.75%. The Healthy and Leaf Blight classes were identified with 100% accuracy. This classification model was integrated into a web application built on the Flask framework as a practical implementation to support smart a validation accuracy of 91.25%, whereas the 80:10:10 split resulted in an accuracy of 88.75%. The Healthy and Leaf Blight classes were identified with 100% accuracy. This classification model was integrated into a web application built on the Flask framework as a practical implementation to support smart agriculture systems.

Abstrak- Penyakit pada tanaman anggur sering menjadi kendala utama yang menyebabkan penurunan kualitas dan kuantitas hasil panen apabila tidak dideteksi sejak dini. Identifikasi penyakit secara manual umumnya membutuhkan keahlian khusus, ketelitian tinggi, dan waktu yang relatif lama. Penelitian ini bertujuan untuk membangun model klasifikasi otomatis penyakit pada daun anggur berbasis Deep Learning menggunakan metode Convolutional Neural Network (CNN) dengan arsitektur dasar DenseNet121. Dataset yang digunakan berupa 1.600 citra digital daun anggur hijau (Vitis vinifera L. var. Thompson Seedless) yang dikumpulkan dari perkebunan di Kecamatan Sukaraja, Kabupaten Bogor. Citra tersebut terbagi rata ke dalam empat kelas kondisi: Healthy (Sehat), Black Measles (Esca), Leaf Blight (Isariopsis Leaf Spot), dan Black Rot. Pengujian model dilakukan menggunakan dua skenario pembagian proporsi data, yaitu 80:10:10 dan 70:15:15. Hasil penelitian menunjukkan bahwa arsitektur DenseNet121 mampu mengekstraksi karakteristik visual citra secara optimal. Performa terbaik dicapai pada skenario proporsi data 70:15:15 dengan tingkat akurasi validasi sebesar 91,25% , sedangkan proporsi 80:10:10 menghasilkan akurasi sebesar 88,75%. Kelas Healthy dan Leaf Blight berhasil diidentifikasi secara sempurna dengan akurasi 100%. Model klasifikasi ini diintegrasikan ke dalam aplikasi web berbasis framework Flask sebagai implementasi praktis pendukung sistem pertanian cerdas (smart agriculture).
