| Abstract (English): |
Yellow curling symptoms on chili leaves are generally caused by Begomovirus infection. The leaves of infected plants not only change color as an indicator of chlorophyll damage but also experience changes in morphological shape. This research aims to quantify the symptoms of Begomovirus infection based on morphological changes in leaf shape using digital image processing and data mining algorithms that will facilitate monitoring and analysis of plant disease development. A total of 33 images of cayenne pepper leaves with yellow curly symptoms and without symptoms became the dataset of this study. Using the Fiji-ImageJ application, the chili leaf images were processed and extracted in the shape characteristics, i.e., circularity, aspect ratio, roundness, and solidity. Furthermore, a t-test and image clustering using the Simple K-Means algorithm was conducted, followed by evaluation of the accuracy of the clustering results based on the ARI and NMI indexes. The results showed that, in general, there was a significant difference in shape between symptomatic and non-symptomatic leaves. The ratio and solidity value of leaves with yellow curly symptom was smaller than those of non-symptomatic chili leaves. In contrast, circularity and roundness value of symptomatic leaves was larger than those of non-symptomatic chili leaves. Evaluation of the accuracy of samples grouping for cayenne pepper leaves with and without symptoms based on the ARI and NMI indicated that grouping them into two groups gave the best value.

| Abstract (Indonesian): |
Gejala kuning keriting pada daun cabai umumnya disebabkan oleh infeksi Begomovirus. Daun tanaman terinfeksi tidak hanya mengalami perubahan warna sebagai indikator rusaknya klorofil tetapi juga mengalami perubahan morfologi bentuk. Penelitian ini bertujuan menguantifikasi gejala infeksi Begomovirus berdasarkan perubahan morfologi bentuk daun menggunakan pengolahan citra digital dan algoritma data mining yang akan memudahkan dalam pemantauan dan analisis perkembangan penyakit tanaman. Total 33 citra daun cabai rawit bergejala kuning keriting maupun tidak bergejala menjadi dataset penelitian ini. Citra daun cabai tersebut diolah dan diekstrak karakteristik bentuknya berupa circularity, aspect ratio, roundness, dan solidity menggunakan aplikasi Fiji-ImageJ. Selanjutnya dilakukan uji beda (uji-t), pengelompokan citra menggunakan algoritma Simple K-Means, dan evaluasi ketepatan hasil pengelompokan berdasarkan indeks ARI dan NMI. Hasil penelitian menunjukkan bahwa secara umum ada perbedaan bentuk yang nyata antara daun bergejala dengan daun tidak bergejala. Daun cabai rawit bergejala kuning keriting memiliki rata-rata nilai aspect ratio dan solidity yang lebih kecil dibandingkan daun cabai tidak bergejala, sebaliknya memiliki rata-rata nilai circularity dan roundness yang lebih besar dibandingkan daun cabai tidak bergejala. Evaluasi ketepatan pengelompokan sampel daun cabai rawit bergejala maupun tidak bergejala berdasarkan indeks ARI dan NMI menghasilkan nilai terbaik untuk pengelompokkan ke dalam dua kelompok.
