Abstract.
Segmentation in images of flowers or plants is an important pre-process in the field of botany, one of which is for identifying diseases of flowers or other plants. One of the problems in the image segmentation is the segmented images produced automatically. It is due to the long period of time needed to produce segmented images manually. To overcome these issues, a clustering process was carried out using the k-means algorithm. In this study segmentation is done by using Lab color space and RGB as a comparison to K-means in clustering the image of daisy flowers. Good results are showed by the Lab color space in the clustering process that 60% of the data has lower silhouette coefficient than RGB color space and 3.94% as the mean of s negative.

Abstrak.
Segmentasi pada citra bunga atau tanaman merupakan pra proses yang penting dalam bidang botani, salah satunya untuk mengidentifikasi penyakit pada bunga atau tanaman lainnya. Salah satu permasalahan dalam segmentasi citra adalah menghasilkan citra tersegmentasi secara otomatis. Hal tersebut dikarenakan kebutuhan akan waktu yang tidak sebentar untuk menghasilkan citra tersegmentasi secara manual. Untuk mengatasi kendala tersebut dilakukan proses klasterisasi dengan menggunakan algoritma K-means. Pada penelitian ini segmentasi dilakukan dengan menggunakan ruang warna Lab dan RGB sebagai pembanding kinerja k-means dalam mengklasterisasi citra bunga Desi. Hasil yang baik dimiliki oleh ruang warna Lab dalam proses klasterisasinya, yaitu dengan 60% data memiliki nilai silhoutte coeficient (s) yang lebih kecil dari ruang warna RGB dan memiliki rata-rata sebesar 3.94% s negatif.
Kata Kunci: Segmentasi, Lab, k-Means
