Pemanfaatan Kompos Bioaktif Untuk Meningkatkan Pertumbuhan Dan Ketahanan Padi Gogo Terhadap Penyakit Blas Di Lapangan
Get PDFPadi merupakan bahan pangan pokok Bangsa Indonesia yang memiliki nilai strategis dan nilai ekonomi tinggi, yang mengharuskan ketersediaannya selalu mencukupi dan sinambung. Produksi padi pada 2007 sebesar 57,05 juta ton gabah kering giling (GKG) meningkat 4,76% dibandingkan dengan produksi 2006, yaitu sebesar 3,5 juta ton gabah kering giling. Selanjutnya pemerintah menargetkan produksi padi 2008 mencapai 61 juta ton GKG. Peningkatan produksi yang diharapkan dari penanaman padi di lahan sawah serta peningkatan produksi padi dari perluasan sawah masih belum sebanding dengan konversi sawah menjadi lahan non pertanian. Di sisi lain, penanaman padi gogo dengan memanfaatkan lahan kering merupakan potensi yang bisa dikembangkan. Ketersediaan lahan kering nasional yang lebih luas dari luas sawah nasional yang dapat dioptimalkan manfaatnya dengan penanaman padi gogo yang lebih intensif, berikut dengan pengelolaan hama dan penyakitnya dapat diharapkan mendukung ketahanan pangan secara nasional
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Pengaruh Variasi Lebar Bilah Bambu Terhadap Keruntuhan Geser Balok Bambu Laminasi Dengan Susunan Bilah Vertikal Sebagai Suplemen Bahan Ajar Konstruksi Bambu
Get PDFPenelitian ini bertujuan untuk (1) Mengetahui sifat-sifat fisika dan mekanika bambu petung, yaitu kadar air, kerapatan, kuat tarik sejajar serat, kuat tekan sejajar serat, kuat lentur, kuat geser dan modulus elastisitas terhadap kelas kuat kayu. (2) Mengetahui pengaruh variasi lebar bilah bambu (10 mm, 15 mm, 20 mm) dengan susunan vertikal terhadap modulus elastisitas (MOE), kuat lentur (MOR) dan tegangan geser (τ) bambu laminasi. (3) Mengetahui nilai optimal variasi lebar bilah bambu dengan susunan vertikal terhadap modulus elastisitas (MOE), kuat lentur (MOR) dan tegangan geser (τ) bambu laminasi. (4) Mengetahui nilai optimal variasi lebar bilah bambu dengan susunan vertikal modulus elastisitas (MOE), kuat lentur (MOR) dan tegangan geser (τ) bambu laminasi terhadap kelas kuat kayu. Penelitian ini menggunakan metode kuantitatif eksperimen dan teknik analisis data menggunakan analisis regresi sederhana. Variabel yang mempengaruhi dalam penelitian ini adalah (1) variabel bebas / independen : variasi lebar bilah bambu (10 mm, 15 mm, 20 mm) dengan susunan vertikal. (2) variabel terikat / dependen : modulus elastisitas, kuat lentur dan tegangan geser. Berdasarkan hasil penelitian disimpulkan bahwa, (1) sifat fisika dan mekanika bambu petung termasuk dalam kelas kuat kayu II. (2) penggunaan variasi lebar bilah bambu (10 mm, 15 mm, 20 mm) dengan susunan vertikal berpengaruh terhadap nilai modulus elastisitas (MOE), kuat lentur (MOR) dan tegangan geser (τ). (3) Nilai optimal modulus elastisitas (MOE) menggunakan variasi lebar bilah bambu 10 mm sebesar 6492,60 MPa. Nilai optimal kuat lentur (MOR) menggunakan variasi lebar bilah bambu 15 mm sebesar 69,44 Mpa. Nilai optimal tegangan geser (τ) menggunakan variasi lebar bilah bambu 15 mm sebesar 6,94 Mpa. (4) Nilai optimal variasi lebar bilah bambu dengan susunan vertikal modulus elastisitas (MOE), kuat lentur (MOR) dan tegangan geser (τ) bambu laminasi termasuk dalam kelas kuat kayu III
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
