Kinerja Pertumbuhan dan Sintasan Benih Ikan Gabus Channa striata yang Dipelihara dengan Kedalaman Air Berbeda pada Kolam Terpal.
No full textPenyediaan benih ikan gabus Channa striata dari hasil budidaya masih terkendala pertumbuhan dan sintasan yang masih rendah. Penyediaan lingkungan yang nyaman melalui kedalaman air diduga mampu meningkatkan kinerja pertumbuhan dan sintasan pada pemeliharaan benih ikan gabus. Penelitian bertujuan mengevaluasi kedalaman air terbaik untuk kinerja pertumbuhan dan sintasan benih ikan gabus yang dipelihara pada kolam terpal. Rancangan penelitian yang digunakan yaitu rancangan acak lengkap dengan tiga perlakuan dan masing-masing diulang tiga kali. Perlakuan yang diberikan adalah kedalaman air yaitu: 10 cm, 20 cm, dan 30 cm. Selama pemeliharaan, benih ikan gabus diberi pakan dengan feeding rate (FR) 8 % dan frekuensi pemberiannya empat kali dalam sehari. Hasil penelitian menunjukkan bahwa kinerja pertumbuhan dan sintasan benih ikan gabus terbaik diperoleh pada kedalaman air 20 cm. Hasil perhitungan terhadap laju pertumbuhan spesifik tertinggi dicapai pada kedalaman air 20 cm yaitu 4.81 %/hari dan nilai sintasan mencapai 91.21%. Hasil analisis gambaran darah juga menunjukkan benih ikan gabus tidak terindikasi stres pada perlakuan kedalaman air 20 cm dengan nilai total eritrosit 1.53±0.51×106 dan total leukosit 3.71±0.13×104
Sintasan Dan Pertumbuhan Larva Ikan Gabus Channa Striata Pada Media Alkalinitas Yang Berbeda
No full textProduksi ikan gabus (Channa striata) masih disuplai dari perikanan tangkap. Kegiatan budidaya masih terkendala karena sintasan dan pertumbuhan larva ikan gabus masih rendah. Penelitian ini bertujuan memperoleh konsentrasi alkalinitas yang terbaik terhadap sintasan dan pertumbuhan larva ikan gabus. Larva ikan gabus dengan bobot dan panjang tubuh rata-rata 0,0086 ± 0,0001 gram dan 0,7 ± 0,045 cm dipelihara pada bak plastik berukuran 40x25x20 cm sebanyak 500 ekor (34 ekor/liter) dengan volume air 15 liter. Ikan dipelihara selama 24 hari dan diberi pakan berupa cacing sutera cacah sebanyak tiga kali sehari dengan metode pemberian secara at satiation. Rancangan penelitian menggunakan metode rancangan acak lengkap. Perlakuannya terdiri dari alkalinitas 25-30, 50- 55, 75-80, dan 100-105 mg/L CaCO3. Setiap perlakuan terdiri dari tiga ulangan. Hasil penelitian menunjukkan bahwa konsentrasi alkalinitas 50-55 mg/L CaCO3 dapat meningkatkan sintasan dan laju pertumbuhan sebesar 52,20 ± 0,80 % dan 13,81 ± 0,19 %. Dengan demikian sintasan dan pertumbuhan larva ikan gabus yang terbaik diperoleh pada konsentrasi alkalinitas 50-55 mg/L CaCO3
Hermeneutika MaqÄá¹£idÄ« Imam al-ShÄá¹ibÄ«
No full textAl-SyÄá¹ibÄ« is one of the scholars who have innovative thought on Qur’anic hermeneutics in the classical Muslim scholarship. He was proposed a “reading based on maqÄṣīd†on the shari’a which differed from that of earlier methods. Marginally, Al-SyÄá¹ibī’s hermeneutic abbreviation comprised of three tenets: (1) accentuating Arabic aspect as foothold in interpretation process on the shari’a, (2) emphasizing reading base on maqasid through circular-relational study on text-author-reader and other various accompaniment indicators, and (3) acknowledging reader circumstance role in the process of interpretation, so that no single-objective truth in interpretation
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

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
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
