Raya Tlogomas 246 MalangEmail: [email protected] is a colorless clear liquid, volatile, has a pungent aroma and a patio painful skin. In theworld of education the ethanol is used as a disinfectant and solvent in various studies, besides thatethanol can also be a source of energy to overcome the energy crisis. In previous studies of soybeanhusk waste tempe production which has been a waste and can be raw material for ethanol fermentationprocess. The purpose of this research is to increase ethanol soybean husk production, by controllingthe temperature and pH of the fermentation process.The research was conducted in the ITP FPP UMM laboratory by controlling the fermentationtemperature at temperatures 30oC, 35oC, 40oC and pH 4.5, 5, 5.5. The parameters measured werethe levels of ethanol, reducing sugar and pH changes during fermentation 12, 24 and 36 hours.The results showed that the treatment temperature is 30oC with pH 4.5 produce ethanol withthe highest levels of 4.071% at the 36. while the production of ethanol using the fastest treatment at40 oC ph5, 5 at the 12 with 2.748% ethanol levels but decreased thereafter.Keywords: ethanol, soy bran, temperature, pH, fermentation
Analisis Tingkat Resiko Gangguan Musculoskeletal Disorder (MSDs) Pada Pekerja Konveksi Sablon Plastik dengan Metode REBA dan OWAS
Get PDFHuman labor plays a vital role, especially in Manual Material Handling (MMH) processes. While these activities are crucial for smooth operations, they often lead to musculoskeletal disorders (MSDs). MSDs are long-term consequences of improper workstation postures. This research aims to identify the working postures of screen printing workers and propose ergonomic desk designs as improvements. The REBA and OWAS methods can be applied. REBA focuses on assessing the entire body posture of workers, while OWAS aims to identify work activities that potentially cause MSDs. The calculated REBA score is 7, and the OWAS score is 2, indicating a need for preventive measures. The proposed solution is an ergonomic desk design that adjusts to the worker's height
OPTIMALISASI ZAT GIZI PADA PROSES PERKECAMBAHAN PEMBUATAN TAOGE : Kajian Suhu Dan Lama Perendaman
No full textBean sprouts has high nutrition value, cheap, and easy to get. The making process of bean sprouts is very simple, that is by germination process. Germination process increases digestion power because germination is a catabolic process that serves important nutrition for plant growth by hydrolytic reaction of reserve nutrition in the seed. Germination is affected by the condition and place. The aim of this study is to know the effect of submergence water and the duration of submergence to the bean sprouts\u27 quality and the increase of the nutrition of bean sprouts. The result of this research shows that the temperature of water and the duration of submergence gives different quality and different increase of the nutrition of bean sprouts (water degree, dust degree, rendemen, vitamin c, fat degree, reduction sugar degree, protein degree, and density). From the result of this research, it is expected to the increasing of food quality. So, it will be implicated to better health quality of the people
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
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
