Edukasi Pengaruh pH Media dan Lama Fermentasi Terhadap Basil Nata de Coco
Full text linkNata is one of the organic food products that has a high fiber content. Nata is a product of fermentation by Acetobacter xylinum. The review that discusses the making of nata by analyzing the effect of the pH of the media and the duration of fermentation at the same time is still very limited. Thus, this review aims to discuss the effect of media pH and fermentation time on nata de coco bacilli. Paying attention to the factors that affect the growth of Acetobacter xylinum bacteria during the fermentation process needs to be done so that it can produce nata de coco with optimum thickness and weight and a chewy texture. These factors include the pH of the media and the length of fermentation. The ingredients for making nata de coco consist of coconut water, granulated sugar, ZA or Ammonium phosphate, and Acetobacter xylinum seeds. The method of implementing the activity which consists of counseling and practice of making nata de coco is able to increase the knowledge of residents, teachers, students (i) about nata de coco and coconut water which are potential natural plants (natural products), as well as skills (soft skills) in making nata de coco. The teachers, students(i) and residents admitted that they were greatly helped by this activity as a form of training that could be applied in their daily lives in entrepreneurship, even though it was a small scale.Keyword: nata de coco, media pH, fermentation time, educatio

Full text linkGiven the existence of plastic waste in the environment is very dangerous, therefore it is necessary to conduct research to handle it. The development of technology for plastic processing to produce something useful continues to be carried out by various groups, ranging from scientists, academics, and students. One of them is the utilization of plastic waste into fuel oil (BBM) using the pyrolysis technique which will be installed to process plastic waste. The purpose of this study was to determine the fuel oil from processing plastic waste and compare the fuel with kerosene and diesel oil with the parameters of density, burning time and water temperature when heating using the three fuel oils. The research method used is data collection techniques including pre-treatment, the process to determine the density of each fuel sample, the process of burning time, temperature during heating, analysis of the density of pyrolysis oil, kerosene and diesel fuel by measuring the volume and the mass of each sample. Comparison of the quality of Fuel Burning Time, namely Oil from recycled plastics 4.01 minutes, Diesel Oil 4.45 minutes, and Kerosene 3.02 minutes. Comparison of the quality of water temperature with a volume of 20 ml of water and a heating time of 5 minutes, it is found that recycled plastic oil is 0.77oC, diesel oil is 0.73oC, kerosene is 0.84oC. plastic waste processing is under kerosene but above diesel oil based on density indicators, burning time, water temperature when heating.Given the existence of plastic waste in the environment is very dangerous, therefore it is necessary to conduct research to handle it.

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
