PENGARUH PUPUK ORGANIK DAN UMUR DEFOLIASI TERHADAP BEBERAPA ZAT GIZI SILASE RUMPUT GAJAH (Pennisetum purpureum)
Full text linkSuatu penelitian dilaksanakan dengan tujuan untuk mengetahui pengaruh pupuk organik dan umur defoliasi terhadap beberapa zat gizi silase rumput gajah (Pennisetum purpureum). Penelitian ini menggunakan rumput gajah, pupuk kompos, dan pupuk organik cair. Penelitian disusun berdasarkan rancangan acak lengkap pola factorial 3 x 3 dengan 3 kali ulangan, sebagai faktor pertama adalah pemupukan: A1 (tanpa pemupukan), A2 (pemupukan dengan kompos) dan A3 (pemupukan dengan pupuk cair), sedangkan faktor kedua adalah umur defoliasi: B1 (umur defoliasi 30 hari), B2 (umur defoliasi 45 hari) dan B3 (umur defoliasi 60 hari). Hasil penelitian menunjukkan bahwa kandungan protein kasar silase rumput gajah pada umur defoliasi 30 hari lebih tinggi daripada perlakuan umur defoliasi 45 hari dan 60 hari. Sedangkan kandungan serat kasar teritnggi diperoleh pada umur defoliasi 60 hari. Defoliasi rumput gajah pada umur 45 hari dan diberi pupuk kompos dapat meningkatkan kandungan lemak kasar dan BETN silase rumput gajah
PENGGUNAAN UMBI TALAS SEBAGAI BAHAN ADDITIVE TERHADAP BEBERAPA UNSUR KIMIA SILASE RUMPUT GAJAH MINI
Full text linkPenelitian bertujuan untuk mengetahui pengaruh umbi talas sebagai bahan additive terhadap beberapa unsur kimia silase rumput gajah mini. Penelitian ini menggunakan rumput gajah mini dan tepung umbi talas sebagai zat additive. Penelitian disusun berdasarkan Rancangan Acak Lengkap (RAL) sebanyak 16 unit percobaan, yang terdiri dari 4 perlakuan dan 4 kali ulangan. Perlakuan terdiri dari : T0 = Rumput gajah mini tanpa tepung umbi talas (control); T1 = Rumput gajah mini + 6% tepung umbi talas jepang; T2 = Rumput gajah mini + 6% tepung umbi talas bogor; dan T3 = Rumput gajah mini + 6% tepung umbi talas sutra. Hasil penelitian menunjukkan bahwa pemberian tepung umbi talas berpengaruh nyata ( P<0,05 ) terhadap kandungan protein kasar, serat kasar dan ADF tapi tidak berpengaruh nyata ( P>0,05 ) terhadap kandungan NDF silase rumput gajah mini. Kesimpulan bahwa kandungan protein kasar silase rumput gajah mini yang menggunakan tepung umbi talas lebih tinggi daripada silase tanpa tepung umbi talas. Kandungan serat kasar pada perlakuan tanpa tepung umbi talas lebih tinggi dibanding silase yang menggunakan tepung umbi talas. Kandungan NDF dan ADF silase dari rumput gajah mini yang menggunakan tepung umbi talas lebih rendah dibanding silase tanpa tepung umbi talas. Silase yang menggunakan tepung umbi talas sutra lebih baik daripada perlakuan lainnya
PENGARUH ENERGI-PROTEIN RASIO (EPR) RANSUM LOKAL YANG BERBEDA TERHADAP PERFORMA DAN BERAT KARKAS BROILER
No full textLatterly most published research concerning the poultry production is an increasingly important part of agriculture, but it also were the highest producers of ammonia gas (NH3) emissions of all domesticated species. One potential strategy for reducing NH3 emission is by formulating diets to precisely meet the nutrient needs. The objective of this study was to determine the effects of energy-protein ratio (EPR) using different local diets on performance and carcass weight of broilers. A total of 120 unsex doc strain SUR-707 were randomly into 4 groups and 6 replicates, and each group was fed one of four dietary treatments. The treatments were : Control; Tapioca meal; Sago meal; and Seaweeds meal. All local diets were formulated to be isoprotein and isocalorie and EPR = 1 : 219 to meet nutrient recommendation of the National Research Council (NRC) for broilers. Results show that the differences of local diets were significantly impact (P < .05) to feed consumption, weight gain, live weight, and carcass percentage; but there were no significant differences in feed conversion and indicate that sago meal has less carcass weight than the tapioca meal treatment. In conclusion, feeding broilers by diet containing tapioca meal with a constant EPR has advantage affected the carcass weight
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
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
