Potensi Inokulasi Jamur Trichoderma viride dan Glomus sp. Terhadap Produktivitas Capsicum annuum L
Full text linkCabai rawit (Capsicum annuum) merupakan komoditi pertanian yang digunakan dalam berbagai jenis produk makanan. Pemanfaatan pupuk anorganik berdampak buruk terhadap lingkungan sehingga diperlukan agen hayati, seperti Trichoderma viride dan fungi mikoriza arbuskula (FMA) untuk memperbaiki kondisi tanah. Tujuan penelitian ini mengobservasi pemberian kombinasi T. viride dan FMA Glomus sp. Terhadap produksi cabai rawit serta mengetahui dosis kombinasi optimum dalam meningkatkan produktivitas cabai rawit. Penelitian dilakukan di laboratorium Taksonomi Tumbuhan/Mikologi dan green house Program Studi Biologi, Fakultas MIPA, Universitas Udayana. Penelitian menggunakan Rancangan Acak Kelompok dengan lima perlakuan yaitu (A) tanah steril (Kontrol negatif); (B) tanah steril dan 50 spora Glomus sp.; (C) tanah steril dan 2 g pupuk anorganik CPN15-0-14 KNO3 Merah; (D) tanah steril, 5 mL T. viride dan 50 spora Glomus sp.; (E) tanah steril, 10 mL T. viride dan 50 spora Glomus sp. Setiap perlakuan memiliki lima ulangan yang terdiri dari tiga unit tanaman. Pengamatan dilakukan terhadap tinggi tanaman, jumlah buah, berat basah dan berat kering buah, berat kering tajuk, berat kering akar dan infeksi FMA. Hasil penelitian menunjukkan bahwa penambahan pupuk anorganik menghasilkan nilai tertinggi pada hampir seluruh parameter yang diamati kecuali pada persentase kolonisasi FMA. Perlakuan E menunjukkan hasil yang lebih optimum dalam produksi cabai rawit meski belum mampu menandingi pupuk anorganik.Cabai rawit (Capsicum annuum) merupakan komoditi pertanian yang digunakan dalam berbagai jenis produk makanan.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Studi Anther Tanaman Tebu (Saccharum officinarum L.) sebagai Tanaman Donor Kultur Mikrospora
No full textSugarcane is an economically valuable plant that continues to be developed to produce superior varieties, the technique to get new varietis used is microspore culture biotechnology. There are many obstacles in the implementation of the microspore cultivar method. Therefore, in this research, a study of sugarcane anthers was carried out. This research used sugarcane panicles for anther selection and then observed under a microscope. Data is analyze with descriptivey method. The results show that white and yellow anthers are the right materials for microspore culture donor
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Genetic Variations and Kinship of Coconut Padma (Cocos nucifera, L. 'Padma') in Bali Based on Microsatellite DNA Marker
Full text linkThe Padma coconut is unique coconut that characterised by six sulci on epicarpium. There are four trees were found only at Ngis village in Manggis distric, Karangasem Regency, Bali Province. The research were conducted to chracterised genetics variation and relationship between padma coconut and other coconuts based on DNA microsatellites markers. Samples were collected from 10 trees from Ngis village (Padma, coklat, hijau biasa, hijau steril, bulan, mulung and kapas coconut). Result showed that genetic diversity was accessed by investigating 10 simple squence repeat (SSR) loci, this provided a total of 53 alleles, 25 alelles 1-5 allel on Padma coconut and 38 ranging from 2-7 alleles per locus on the others coconut. Four of 10 loci are monomorphyc (CNZ01, CNZ51, CnCirC3 and WCYZ8635). The mean Polymorphism Information Contents (PIC) ± 0.7035. The mean values of heterozigosity expected (He) and observed heterozigosity (Ho) were 0.461 ± 0.186 and 0.325, respectevely. The trees grouped into three clusters in the dendogram. Cluster 1 consisted of four trees padma coconut. Cluster 2 consisted of three trees (coklat, hijau biasa, and hijau steril coconut). Cluster 3 consisted of three trees (bulan, mulung and kapas coconut). Keywords: Padma Coconut (Cocos nucifera, L. ’Padma’), DNA microsatellite, SSR, Heterozigosity, locu
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
