Pengaruh Pemberian Filler Abu Cangkang Lokan Terhadap Parameter Marshall Pada Campuran Aspal Beton
Get PDFWest Aceh has a coastline area and a river that drains water into the sea which is quite extensive and produces a lot of supply of lokan species that live in the river. Lokan is a special food that is served by many noodle stalls and restaurants in the area, while the shells become waste that has not been fully utilized. The availability of these shells originating from household waste has inspired the author to conduct research on the use of these as fillers. The shell fillers have little in common with cement fillers are equally lime-containing which can improve the carrying capacity of a mixture. The price is also cheaper and friendly to the environment. From this study the authors wanted to find out the effect of graft ash filler on Marshall parameters on concrete asphalt mixture. The research carried out refers to the technical specifications of the Department of Public Works 2010. Variations in the filler mixture used have different compositions. The percentage of filler used for each variation is the addition of 0% cement filler and 100% shell ash, 20% cement ash filler addition and 80% shell ash, and 50% cement ash filler addition and 50% shell shell ash. The results obtained for optimum bitumen content in variations of 0/100, 20/80 and 50/50 were 4.8%, 4.5%, and 4.9% respectively. From the Marshall evaluation results obtained the highest stability values at variations of 0/100, and the lowest in the variation of 50/50, this shows that the higher the content of shell shell ash will increase the higher carrying value but less flexible
ANALISIS MODEL TARIKAN PERGERAKAN PADA SEKOLAH DI KOTA MEULABOH
Get PDFSchool is one type of land use that can produce trip attraction.This study was conducted to find out the factors that influences the trip attarction of school and build a model that can be used to estimate the tripattraction because of the students vehiclein the school are on Manekroo street, Meulaboh.This study was also conduct to determine the validity of the model by using the value of coefficient determination (R2).Data collection in this study was conducted by calculating the the number of vehicles movementsin the schools reviewed, on coming hours and on out hours.The data are analyzed using multiple linear regression analysis with using SPSS software version 20. The reults indicate that the most influencing variable is the number of students. Calculation results obtained model resylting fromcalculation is Y = 38,575 + 0,911 X1, which Y is the total number of trip attraction in Schools (smp/jam) and X1 is a umber of students. The validity of the model using coefficient determination is 0,993 ; it means the equation is feasible for estimating the value of dependent variable. Keywords : Model, Trip Attraction, School, SPS
Evaluasi Penerapan Keselamatan dan Kesehatan Kerja Pada Gedung Perawatan Jiwa RSUD Nagan Raya
Get PDFThe construction industry is a sector that has a high level of risk both in terms of business risks, occupational health and safety risks. The lack of OHS implementation, resulting in increased work accidents in construction projects. OHS in the Construction Industry needs special attention, it can cause harm to workers, employers, the government and the community, which can be human casualties, property damage and the environment around the project. This study aims to determine the application of OSH in the New Building Care project at Nagan Raya Hospital and to determine the factors that influence OSH in the project. OSH evaluation is carried out by giving questionnaires to the project implementers then performed univariate and bivariate analysis to determine the relationship between variables. The number of respondents 25 people. The results obtained are the most dominant age 16-20 years and at least 42-44 years. The highest level of education in the group without school and the lowest S. The average work period of workers is 10-15 years by 40%. The results of univariate analysis, the frequency distribution for answers "less" is 61.5% for site managers, as well as implementers who answer "no" with a frequency of 60.0% and supervisors 41.7%. This indicates the lack of application of OSH to the project concerned. This is due to the lack of knowledge about OSH management systems and concepts both from the site manager as the project manager, implementer and supervisor so that workers do not get a proper understanding of the OSH
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
