“…The presence of a green shoulder was reported as the most important contributor (with five other traits) of PC1 (Tembe et al, 2018). The fruit shoulder shape was one of two main traits contributing to PC1 reported in a study in Nigeria (Ao et al, 2017) However, several other traits that were not fruitrelated or were evaluated as non-significant contributors for the main PCs in this study, such as bio-chemical traits and leaf traits, were reported as the main components to distinguish the experimental genotypes in other studies in Spain and Serbia (Glogovac et al, 2012;Cebolla-Cornejo et al, 2013). Conversely, the results of this present study suggested that the shape of the pistil scar should be considered as an important trait for the main PCs (Table 5), which has not been reported in any previous study.…”

Tomato is one of the most important vegetables cultivated in Vietnam. Besides its regular consumption as a vegetable, a new demand for using tomato as a decorative plant on special occasions was identified in recent years. This study aimed to characterize new tomato accessions on their desirable morphological traits to select potential materials for further breeding programs of ornamental tomato varieties in Vietnam. Twenty-four heirloom tomato genotypes were evaluated on 19 morphological traits. Based on the describing system for tomato developed by the International Plant Genetic Resources Institute (IPGRI, 1996), significant variation was assessed in both qualitative and quantitative traits related to fruit morphology. The results of principle component analysis indicated that three main principle components explained over 60% of the total phenotypic variation. The five traits of fruit size, fruit shoulder shape, fruit cross-sectional shape, number of locules, and shape of the pistil scar were recommended as important traits for clustering tomato genotypes in this study. In addition, the 24 genotypes were classified at the coefficient of 0.39 into six different clusters. Finally, six interesting accessions, AU66, AU67, AU68, AU73, AU79, and AU83 (with strange fruit colors and shapes), were selected as potential materials for further breeding programs of ornamental tomato in Vietnam.

Segmentasi rambu jalan dan sistem pengenalan merupakan aspek penting dan esensial untuk digunakan pada sistem autopilot, smart car atau autonomous vehicle yang memungkinkan kendaraan dapat berjalan tanpa pengemudi manusia. Namun demikian pada paper ini citra rambu jalan yang diproses dalam bentuk image dan bukan vidio/kamera. Penelitian ini bertujuan memperoleh citra warna rambu jalan dengan presisi yang tinggi. Pada penelitian ini ditawarkan metode segmentation rambu jalan dengan mengembangkan Fuzzy C-means dengan menginjeksikan teknik mask-tresholder untuk mendapatkan hasil segmentasi warna rambu jalan dengan presisi tinggi. Mula-mula citra dideteksi dalam ruang warna RGB kemudian diubah menjadi model warna L*a*b dan dilanjukan ekstraksi untuk mendapatkan komponan warna *a*. Fuzzy C-means dterapkan pada citra warna *a* untuk segmentasi foreground dan background. Proses dilanjutkan dengan operasi opening – closing dan hole filling untuk mereduksi noise pada hasil segmentasi. Sampai pada tahap ini hasil segmentasi yang diperoleh adalah citra binary dimana foreground dalam warna putih dan bacground dalam warna hitam. Oleh karena itu untuk mendapatkan citra hasil segmentasi rambu jalan dalam ruang warna RGB maka diperlukan proses konvolusi. Teknik konvolusi yang dilakukan pada penelitian ini adalah dengan mengalikan tiap piksel citra mask tresholder dengan citra semula dalam ruang warna RGB. Citra mask tresholder yang digunakan dalam penelitian ini adalah citra binary hasil segmentasi dengan Fuzzy Cmeans. Metode yang ditawarkan telah diuji dengan citra rambu jalan sejumlah 18 citra. Hasil yang diperoleh menunjukkan kinerja metode yang diusulkan mampu mensegmentasi citra rambu jalan dalam sesuai warna citra semula. Menggunakan metode jaccard untuk mengukur akurasi kinerja didapat tingkat akurasi adalah 97,73%.

“…The morphological characteristic can be recognized by observing plant growth type, plant size, stem pubescence density and length, leaf type, corolla color, the color of immature and mature fruit, seed shape and color. It is a basic concept that important to know if we want to learn about plant (Chime, Aiwansoba, Osawaru, & Ogwu, 2017;Wolsey & Lapp, 2014).…”

Scientific attitudes are considereble aspect to observe in science learning. This study aimed to analyze students' scientific attitudes. In accordance with this aim, the students’ and teachers’ perceptions were recorded. This study was conducted in Junior High School 8 Salatiga. The sample of this research was 33 students and four science teachers. Furthermore, the quantitative data of scientific attitudes were collected using a questionnaire which than were analyzed using mean score. Meanwhile, the qualitative data of students' scientific attitudes and perceptions were collected by interviewing students and teachers. The results of the study showed that the scientific attitudes were catagorized in the range of mean score from 3.2 to 4.7. In addition, the students and teachers showed positive perceptions. To sum up, the green garden-based education could be an alternative model in science learning.
