Analisis Pengelolaan Sampah Terkait Pembangunan Polder Kali Banger Di Wilayah Kecamatan Semarang Timur
Full text linkSemarang is a subdistrict of east lowlands adjacent to the shore which consists of 10 villages and a catchment area Banger. Polder is a flood control system and runoff the community based management is a pilot project in Indonesia, located at the eastern most region of Semarang District land surface elevation below sea level tide. Disposal of rain water that fell in the region to the sea or water bodies need to help pump. In connection with the issue of waste management is carried optimal efforts to hold and manage the garbage that is not transported before it goes into the river and impede performance polder pump. One way of method 3R ( Reuse, Reduce and Recycle ) are performed and optimized in research in this area is to chop / grind waste to reduce its volume ( Volume Reducing Waste / VWR ) and to reduce the air content in the waste compaction using tools hydraulic jack with a capacity of 2 ton ( Hidrolic Compactioning System / HCS ). trial was made with two kinds of conditions in the experiment without the waste samples sorted and experiment with sorted. Of waste compaction test by hand without the obtained results are sorted and enumerated volume reduction of 17.3 % (0.000812 m3 from 0.0047 m3 ) determining the value of the correlation coefficient R2 = 0.821 or R = 0.906, it is meaning that compaction can not be optimal because the condition of waste still influenced by the mix of many types of material and content of the air in it. Further trials compaction of waste with hydraulic equipment and waste sorted and chopped / grinded results obtained R2 = 0.885 or R = 0.940, for the meaning that optimal compaction due to the condition of selected waste (organic) and content of the air inside is removed and segregated garbage can be reused or sold. The continued impact of the measures is a reduction in the number of garbage trucks ritation and can save transportation costs and fuel in accordance with national austerity program. In addition, if the waste disposed to landfill (TPA), the volume reduction process will extend the life of the landfill. The new research is a preliminary study to examine the percentage of reduction in production, reduction of production costs and transport costs in managing the waste that does not go in the garbage or dumped into the Banger. The purpose of this paper is one effort to disseminate to the public and local government in the optimal waste management and integrated with the flood disaster management should be in conjunction with waste manage mentand waste water
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
Kajian Penggunaan Limbah Plastik Sebagai Campuran Agregat Beton
Full text linkThis paper presents the study of the use of waste plastic bags as a mixture of fine aggregate in concrete production 1 pc: 2 Psr: 3 Split, variations in the mix of plastic is added the mortar 0, 1, 1.5, 2, 2.5, 3, 4, and 5 %. Any variation tested mixture compressive strength and tensile strength. With this method can further determined that the most optimum addition of plastic to be used as concrete mix. From the test results showed that the addition of plastics 5% increases the tensile strength of concrete approximately 50% compared with no addition of plastic, in contrast with the addition of the same plastic reduces the compressive strength of 47 %. From these results it can be stated that the addition of plastics will increase its tensile strength so that the inner structure of the fiber tensile cracks will not occur, with the addition of waste plastic bags reduces the density of concrete, so the construction is lighter
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
