Pengaruh Kombinasi Mikro Organisme Lokal Bonggol Pisang Dan Pupuk Npk Terhadap Pertumbuhan Tanaman Jagung Manis (Zea mays saccharata strurt L.) Varietas Bonanza
No full textOne of the limiting factors for sweet corn plant growth is nutrients. The state of nutrients in the soil will determine the yield of sweet corn. To achieve optimum results sweet corn plants require adequate nutrient input. Nutrients are one of the important factors that affect plant growth and development. Fertilization as nutrient fulfillment can be done through the application of a combination of micro organism local (Mol) fertilizer banana hump and NPK compound fertilizer. Provision of micro organisms local and NPK compound fertilizers on sweet corn plants is useful for accelerating the destruction of organic matter, can also serve as additional nutrients and nutrients needed by plants, so as to increase growth and yield of sweet corn plants as expected. The research method used is an experimental method using a single factor randomized block design (RBD). The number of treatments used in this study were 10 treatments which were repeated 3 times. So there are 30 experimental units. The treatments were as follows: A. 300 kg/ha NPK, B. 10 l/ha Mol + 300 kg/ha NPK, C. 20 l/ha Mol + 300 kg/ha NPK, D. 30 l/ha Mol + 300 kg/ha NPK, E. 10 l/ha Mol + 250 kg/ha NPK, F. 20 l/ha Mol + 250 kg/ha NPK, G. 30 l/ha Mol + 250 kg/ha NPK, H. 10 l/ha Mol + 200 kg/ha NPK, I. 20 l/ha Mol + 200 kg/ha NPK, J. 30 l/ha Mol + 200 kg/ha NPK, K. No fertilizer (control). The results showed that the combination of micro organisms local of banana weevil and NPK fertilizer had a significant effect on the growth components. Treatment G with 30 l/ha MOL + 250 kg/ha NPK gave the highest yield of growth components
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
Pengaruh Pemberian Pupuk Silika dan NPK Pada Jarak Tanam Berbeda Terhadap Pertumbuhan dan Hasil Tanaman Padi (oryza sativa l.) Varietas Ciherang
No full textThe silica content (Si) in the soil is decreasing, but in its repair efforts it still escapes the attention of farmers. The experiment was conducted in Experimental Station of Indonesia Center for Rice Research Sukamandi Jaua Village, Ciasem Subdistrick, West Java, from July to November 2020. The objective of the experiment was to get the best combination of silica fertilizer and NPK tailored to the plant plant spacing to increase the growth and yield of rice crops (Oryza sativa L.) Ciherang variety. The research was used experimental method it was arranged in split plot design with 8 threatments and 3 replications. As the main plot was the nurturing of NPK and silica consisting of 6 acts namely: S0 (control), S1 (100% NPK), S2 (100% NPK and 1000 kg/ha Si), S3 (75% NPK and 1000 kg/ha Si), S4 (50% NPK and 1000 kg/ha Si), S5 (100% NPK and 2000 kg/ha Si), S6 (75% NPK and 2000 kg/ha Si), and S7 (50% NPK and 2000 kg/ha Si). As subplot, the plant spacing consists of 2 treatments: P1 (25 x 25 cm) and P2 (40 x 20 x 10 cm). The results showed that there was no interaction between the combination of NPK and silica fertilizers and the plant spacing against all observation parameters. However, there was a real influence on the combination of NPK and silica fertilizer independently on plant height at 60 and 86 days after planting, the number of tillers at 60 days after planting, the number of panicles per m2, 1000 grains weight, and the grain yield. Meanwhile, in the treatment of plant spacing there was only a real influence independently on the number of tillers at 21-86 days after planting and the number of grains. Giving 100% NPK fertilizer and 1000 kg/ha silica with a plant spacing of 25 x 25 cm was the best combination because it was able to provide high yields on plant height parameters, number of tillers, 1000 grains weight and grain yield
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
