Uji Pemberian Palm Oil Mill Effluent (POME) dan Pupuk KCl Terhadap Pertumbuhan dan Hasil Sorgum (Sorghum bicolor (L.) Moench) di Lahan Konversi Kelapa Sawit
No full textPenelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial
dengan 2 faktor, faktor pertama pemberian POME dengan 4 taraf yaitu P0 = Tanpa
Perlakuan (kontrol), P1 = 200 ml +800 ml air, P2 = 300 ml +700 ml air, P3 = 400
ml +600 ml air dan faktor kedua pemberian KCl dengan 4 taraf yaitu K0 = Tanpa
Perlakuan (kontrol), K1 = 10 g/plot, K2 = 20 g/plot, K3 = 30 g/plot. Parameter yang
diukur adalah tinggi tanaman, jumlah daun, diameter batang, panjang malai, bobot
biji per sampel, bobot biji per plot, bobot 1000 biji.
Data hasil pengamatan dianalisis dengan menggunakan analisis of
varians (ANOVA α = 5%) dan dilanjutkan dengan uji beda rataan menurut
Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukan bahwa
pemberian POME hanya berpengaruh nyata pada jumlah daun tanaman sorgum.
Pemberian KCl berpengaruh nyata terhadap panjang malai, bobot biji per sampel,
bobot biji per plot tanaman sorgum. Interaksi antara perlakuan pemberian Palm
Oil Mill Effluent (POME) danpupuk KCl tidak berpengaruh nyata terhadap semua

Karakter Morfologi dan Hasil Sorgum Manis (Sorghum bicolor (L.) Moench) yang Diberi Palm Oil Mill Effluent dan KCl di Lahan Konversi Kelapa Sawit.
Get PDFSorgum merupakan salah satu tanaman yang dapat memberikan banyak manfaat diantaranya dari biji menghasilkan tepung sebagai pengganti gandum, dari batang dapat menghasilkan gula dan hijauan pakan ternak. Berdasarkan rata-rata hasil nasional produktivitas sorgum masih rendah yaitu 2,68 ton ha-1 dengan potensi hasil yang seharusnya mencapai 5-7 ton ha-1, maka perlu dilakukan upaya peningkatan hasil. Upaya yang dapat dilakukan adalah melalui penerapan teknologi budidaya dengan menggunakan pemupukan antara lain pupuk kalium dan pupuk organik Palm Oil Mill Effluent (POME). Oleh karena itu perlu dilakukan penelitian yang menggunakan POME dengan 4 taraf yaitu P0 = Tanpa Perlakuan (kontrol), P1 = 200 ml + 800 ml air, P2 = 300 ml + 700 ml air, P3 = 400 ml + 600 ml air dan pemberian kalium dengan 4 taraf yaitu K0 = Tanpa Perlakuan (kontrol), K1 = 10 g/plot, K2 = 20 g/plot, K3 = 30 g/plot. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial. Data hasil pengamatan dianalisis dengan menggunakan analisis of varians (ANOVA ? = 5%) yang dilanjutkan dengan uji beda rataan menurut Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukan bahwa pemberian POME yang berbeda dosis hanya menunjukkan perbedaan yang nyata pada jumlah daun sedangkan pemberian kalium klorida yang berbeda dosis mempengaruhi secara nyata karakter panjang malai, bobot biji per sampel dan bobot biji per plot. Dari hasil yang diperoleh menunjukkan bahwa ada dosis terbaik perlakuan pupuk kalium klorida yang lebih menunjukkan pengaruh terhadap hasil tanaman sorgum
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
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
