“…This is a very good potential to develop C. x grandiflorum in the cut flower business. The public also demands H. annuus, C. chinensis and G. jamesonii as ornamental plants and cut flowers as flower bouquets and wedding decorations [29,30]. Research has shown that a combination of 25% sugar and acetic acid significantly affects the freshness of flowers G. jamensonii [31].…”

Asteraceae have many species and beautiful flowers that became an attraction for cultivation and were used as ornamental or cut flowers. Asteraceae grow fertile in the high plains, as seen from the diversity of livable species and their phenetic flowers. The purpose of this research was inventory of the Asteraceae ornamental plants of the Gayo’s Highland. Analysis with explorative survey methods was conducted at eight districts in Bener Meriah Regency by conducting direct observations at the location of the statement’s object. The study found 19 species of Asteraceae belonging to 14 genera, including Dahlia, Tagetes, Cosmos, Zinnia, Chrysanthemum, Helianthus, Coreopsis, Tithonia, Melapodium, Tanacetum, Symphyotrichum, Callistephus, Centratherum, and Gerbera. The most commonly found genus is Dahlia, with three species with different color varieties, followed by Tateges, Cosmos, and Tithonia, with two species. This suggests that Dahlia is a favorite species and a potential plant to be chosen as an ornamental plant in the planning of the development of the Asteraceae flower garden as well as a cut flower and increasing its economic value.

“…Where the grayscale color only has a color intensity of 0 -255 for each pixel. The grayscale transformation technique used is the average, where the grayscale image is obtained from finding the average value of the total RGB value using equation (1). The results of the transformation from RGB images into grayscale images from several samples of sunflower images can be seen in Figure 2.…”

Sunflower is an important commodity in agriculture, besides being used as an ornamental plant, sunflower is an oil-producing plant and a source of industrial materials. In Indonesia, sunflower productivity is considered less than optimal, because knowledge and information about sunflowers are still lacking. Therefore, information is needed that can be used as an extension of knowledge about sunflowers itself, especially in Indonesia, which is a tropical region which is an area suitable for the growth of sunflowers. Sunflowers can actually be identified based on recognizable traits. However, the similar shape makes it difficult for some people to distinguish the types of sunflowers. This study aims to classify sunflower images using a first-order feature extraction algorithm using the characteristics of mean, skewness, variance, kurtosis, and entropy which are then used as input to the Multiclass SVM identification algorithm. Data points are mapped to dimensionless space using a Multiclass SVM to produce hyperplane-linear separation between each class. Based on the results of testing the accuracy of the model is able to perform classification with an average accuracy of 79%. These results show that the developed model can classify well.

“…Tanaman bunga matahari memiliki ciri khas yaitu selalu menghadap sinar matahari yang disebut fenomena heliotropisme. Peristiwa tersebut secara alamiah terjadi saat bunga matahari sedang tumbuh dan berkembang karena bunga matahari menyimpan auxin (hormon tanaman yang mengendalikan pertumbuhan (Wahyudi, Rahmasari & Sari 2020) Bunga matahari sering kali dijadikan sebuah objek karya karena keindahan bunganya baik saat mekar bahkan saat sudah layu. Seniman memvisualisasikan bunga matahari dengan karakter dan keunikannya sendiri.…”

The purpose of creating this final work is as a form of aesthetic experience when the author needs calm in living his life. Sunflowers have a philosophy of always following the direction of the sun’s rays, which means being loyal, optimistic and enthusiastic so that sunflowers can be used as an inspiration for those who see them. The issues discussed are: 1) What is interesting about sunflowers as a source of ideas for creating high-print graphic art works, 2) How sunflowers become a theme in high-print graphic art works, 3) How to visualize sunflowers in high-print graphic art works . The objectives of creating this thesis work are: 1) Describe the interesting things about sunflowers, 2) Explain the choice of sunflowers as a source of ideas for creating graphic works of art, 3) Create a visualization of sunflowers as a work of graphic art. Sunflowers are packaged in high-print graphic art visuals with a flow of surrealism and color reduction methods. Presentation of works with figures using matte glass so as not to reflect light. The media used is mdf with a thickness of 3 mm with dimensions of 60 cm x 80 cm. The work is presented by placing it on the surface of the gallery wall using glass figures. Hopefully this work of art can be a reference, useful and enjoyable for the community.
