Get PDFPenelitian dilakukan di Rumah Bayang (Green House)Program Studi Agroteknologi Fakultas Pertanian Universitas Tridinanti Palembang, dimulai dari bulan Maret sampai bulan April 2017. Penelitian ini dilakukan dengan metode percobaan menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 6 kelompok/ulangan. Perlakuan yang diujicobakan adalah konsentrasi larutan hara sebesar 450 ppm (P1), 600 ppm (P2), 750 ppm (P3), dan 900 ppm (P4). Respon tanaman yang diamati yaitu berupa peubah tinggi tanaman (cm), jumlah daun (helai), berat berangkasan basah tanaman (g), berat kering tanaman (g), panjang akar (cm), dan uji organoleptik. Berdasarkan hasil penelitian yang diperoleh, maka dapat disimpulkan bahwa pemberian nutrisi hidroponik dengan konsentrasi 450 ppm (P1)berpengaruh baik terhadap pertumbuhan tanaman selada merah yaitu menghasilkan tinggi tanaman 18,64 cm pada minggu ke-4 dan jumlah daun 21,80 helai pada minggu ke-4, berat berangkasan basah 114,22 g, berangkasan kering 5,94 dan panjang akar 29,18 cm.Kata Kunci : Hidoponik, DFT, Selada Mera
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
RESPON PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) PADA BERBAGAI PERBANDINGAN MEDIA TANAM DI PRE NURSERY
Get PDFGrowth Responses of Oil Palm Seedlings (Elaeis guineensis Jacq.) Comparison Of The Various Growing Media in Pre nursery. The usefulness of this study are expected to be useful for science and technology, and can be used as a guide for people who want to plant oil palm trees. This research has been conducted in the field nursery PT. Mahkota Andalan Sawit at Pedu Village, district Jejawi, Region Ogan Komering Ilir, starting from June 2014 to September 2014 This study used a randomized block design experiment method (RAK) which consisted of 4 treatments and each treatment was repeated 6 times. The treatment under study P1 = 100% top soil (Without Peat soil mix), P2 = 75% top soil and 25% peat soil, P3 = 50% top soil and 50% peat soil, P4 = 25% top soil and 75% peat soil. Variables measured were plant height, stem girth, root fresh weight, root dry weight, number of roots, number of leaves and leaf area. Based on the results of the study showed that 25% of the soil planting medium top soil and 75% peat soils respond well to the growth of oil palm seedlings age 90 Hst with generating plant height, stem girth, root fresh weight, root dry weight and leaf area respectively - also was 25.59 cm; 3,02 cm; 1.40 g; 0.48 g and 1608.75 cm ².

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
