Status gizi merupakan salah satu indikator yang digunakan untuk mengukur keadaan tubuh akibat mengonsumsi makanan dan penggunaan zat-zat gizi. Status gizi dibedakan menjadi 4 kategori, yaitu gizi kurang, gizi baik dan gizi lebih dan obesitas. Konsumsi seseorang berpengaruh pada status gizi seseorang dimana status gizi baik atau status gizi optimal terjadi apabila tubuh memperoleh cukup zat gizi yang digunakan secara efisien, sehingga kemungkinan pertumbuhan fisik, perkembangan otak, kemampuan kerja dan kesehatan secara umum berada pada tingkat yang optimal. Tujuan Penelitian ini adalah Untuk Mengetahui Hubungan Pengetahuan Tentang Jajan Sehat Dengan Status Gizi Anak Di Sekolah Di SDN Mancar 01 Peterongan Jombang. Desain penelitian ini menggunakan analitik korelasi dengan pendekatan cross sectional. Dalam penelitian ini didapatkan populasi 70 siswa/siswi kelas IV,VI dan VI SDN Mancar 01 Peterongan Jombang dengan jumlah sampel 60 responden. Dengan menggunakan teknik purposive sampling. Alat pengumpulan data berupa lembar kuesioner serta analisis data menggunakan uji spearman rho. Hasil penelitian menunjukkan bahwa sebagian besar responden memiliki pengetahuan baik sebanyak 37 responden (61,7%) dan hampir seluruhnya responden memiliki status gizi cukup sebanyak 57 responden (95,0%). Berdasarkan hasil uji spearman rho didapatkan nilai 0,00 < a (0,05), H1 diterima yang berarti ada Hubungan Pengetahuan Tentang Jajan Sehat Dengan Status Gizi Anak Di Sekolah Di SDN Mancar 01 Peterongan Jombang. Siswa/siswi diharapkan memiliki pengetahuan atau informasi yang baik untuk mencegah status gizi buruk dan lebih memperhatikan dalam memilih jajan sehat/makanan ringan untuk dapat memenuhi kebutuhan gizinya.

Olive anthracnose outbreaks caused by the Colletotrichum species complex in the Mediterranean region decrease both fruit yield and olive oil production while also drastically degrading olive oil quality. The presence of various Colletotrichum species able to produce disease symptoms in olive fruits significantly deteriorates the efforts for an efficient crop protection strategy. In this report, the major olive productive area of Peloponnese was screened for Colletotrichum species capable of generating anthracnose symptoms. Olive fruits of 12 different olive cultivars were collected from 60 groves distributed analogously in the Peloponnese. Thirty-two fungal strains isolated from asymptomatic olive drupes were identified morphologically as Colletotrichum spp. and were multilocus genetically analyzed. The 32 isolates were grouped into two primary lineages resembling the previously characterized Colletotrichum acutatum and Colletotrichum nymphaeae based on the conducted genetic analysis for five genetic loci. The virulence of 16 Colletotrichum spp. strains were evaluated in a detached fruit assay of 10 Greek olive cultivars. The results clearly suggested that fungal isolates belonging to both C. acutatum and C. nymphaeae exhibited different levels of pathogenicity in a cultivar-dependent manner. Thus, cultivars examined in terms of the % Disease Index (%DI) were divided into highly tolerant, tolerant, and susceptible, and those analyzed regarding the % Disease Severity Index (%DSI) were divided into tolerant and susceptible. Our results suggest that the Greek cultivars of Athinolia and Megaritiki are highly tolerant to the vast majority of Colletotrichum strains isolated from Peloponnesian groves and consist of a significant genetic material for the future design of crop protection programs against anthracnose breakouts.

Colletotrichum acutatum species complex is one of the most important groups in the genus Colletotrichum with a high species diversity and a wide range of host plants. C. acutatum and related species have been collected from different plants and locations in Korea and deposited into the Korean Agricultural Culture Collection (KACC), National Institute of Agricultural Sciences since the 1990s. These fungal isolates were previously identified based mainly on morphological characteristics, and a limitation of molecular data was provided. To confirm the identification of species, 64 C. acutatum species complex isolates in KACC were used in this study for DNA sequence analyses of six loci: nuclear ribosomal internal transcribed spacers (ITS), betatubulin 2 (TUB2), histone-3 (HIS3), glyceraldehyde3-phosphate dehydrogenase (GAPDH), chitin synthase 1 (CHS-1), and actin (ACT). The molecular analysis revealed that they were identified in six different species of C. fioriniae (24 isolates), C. nymphaeae (21 isolates), C. scovillei (12 isolates), C. chrysanthemi (three isolates), C. lupini (two isolates), and C. godetiae (one isolate), and a novel species candidate. We compared the hosts of KACC isolates with “The List of Plant Diseases in Korea”, previous reports in Korea and global reports and found that 23 combinations between hosts and pathogens could be newly reported in Korea after pathogenicity tests, and 12 of these have not been recorded in the world.
