Pengaruh Kandungan dan Dosis Pupuk NPK Terhadap Pertumbuhan Bibit Tembakau Deli (Nicotiana tabaccum L)
No full textDi bawah bimbingan Dr. Dafni Mawar Tarigan, S.P., M.Si dan
Hadriman Khair, S.P., M.Sc, dilaksanakan pada bulan April 2017 s/d bulan Juni
2017 di Balai Penelitian Tembakau Deli, Kec. Percut Sei Tuan, Kab. Deli
Serdang. Penelitian ini bertujuan mengetahui pengaruh kandungan dan dosis
pupuk NPK. Rancangan yang digunakan adalah Rancangan Petak Terpisah (RPT)
dengan 2 faktor yang diteliti, yaitu : Faktor Kandungan Pupuk NPK (Petak
Utama) terbagi 3 taraf perlakuan yaitu P1 = NPK 15:15:15, P2 = NPK 16:16:16,
dan P3 = 20:20:20 dan Faktor Pemberian dosis pupuk NPK (Anak Petak) terbagi
dalam 3 taraf perlakuan yaitu K1 = 40 gram/plot, K2 = 50 gram/plot, K3 = 60
gram/plot. Sedangkan parameter yang diukur adalah tinggi tanaman, jumlah daun,
luas daun, volume akar, berat basah bagian atas, berat basah bagian bawah, berat
kering bagian atas, dan berat kering bagian bawah. Berdasarkan hasil penelitian
dan hasil sidik ragam dapat diketahui bahwa dari peubah yang telah diamati
interaksi antara kandungan dan dosis pupuk NPK berpengaruh nyata pada tinggi
tanaman dan luas daun umur 5 MSPT serta tidak berpengaruh nyata pada jumlah
daun, volume akar, berat basah bagian atas, berat basah bagian bagian bawah,
berat kering bagian atas, dan berat kering bagian bawah
Probabilitas Keruntuhan Struktur Srpm Beton Bertulang Akibat Gempa Dekat Mengandung Efek Pulse
No full textGempa bumi merupakan fenomena alam yang disebabkan oleh adanya pelepasan
energi regangan elastis batuan pada litosfir. Semakin besar energi yang dilepas
semakin kuat gempa yang terjadi. Indonesia khususnya Kota Banda Aceh
merupakan wilayah yang rawan gempa, sehingga bangunan bertingkat dapat
mengalami kehancuran baik dalam kategori ringan, kecil, sedang, parah bahkan
hancur total. Untuk mengetahui bagaimana perilaku grafik Incremental Dynamic
Analisis (IDA) bila mengandung efek pulse dan Untuk mengetahui probabilitas
keruntuhan struktur bila terkena gempa dekat yang mengandung efek pulse. Oleh
karena itu perlu adanya perencanaan struktur beton bertulang dengan sistem yang
tahan terhadap gempa mengandung pulse. Dalam tugas akhir ini, digunakan 2
daerah sebagai perencanaan gempa yaitu Banda Aceh dan Palembang untuk
memenuhi dalam perencanaan 3 tiga sistem gedung, dalam hal ini terdapat 3
model struktur dengan sistem yang berbeda yaitu, SRPMK, SRPMM, dan
SRPMB. Spesifikasi material dan dimensi struktur berbeda-beda. Model 1
memiliki tinggi 18,5 m (5 lantai), Model 2 memiliki tinggi 36 m (10 lantai),
Model 3 memiliki tinggi 53,5 m (15 lantai). Analisa yang digunakan adalah
Respon Spektrum sebagai tahap desain dan Respon Riwayat Waktu Linear dan
Nonlinear Time History sebagai tahap evaluasi, dengan alat bantu software
SAP2000 versi 15 dan RUAUMOKO2D versi 04. Suatu analisis Incremental
Dynamic Analysis adalah sebuah pendekatan untuk menghasilkan ilustrasi level
kerusakan struktur yang mengalami intensitas seismik yang bervariasi. Hasil
penelitian menunjukkan bahwa struktur dengan SRPMB (Model 3) akan
mengalami angka drift kehancuran yang direncanakan pada RSA (T1) yang tidak
terlalu besar, dikarenakan bangunan memiliki perioda terbesar dan berada pada
jenis tanah luna
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
