PT PAL INDONESIA (PERSERO) is a state-owned company engaged in the construction, maintenance and engineering services provider for upper and subsurface vessels as well as engineering procurement and construction in the energy sector. In this Project Report, the author discusses the pre-alignment shaft propeller process in the manufacture of the 60M W300 and W301 Fast Missile Ships (KCR). In this simulation process, the propeller shaft alignment uses wires that are installed from the center of the gearbox to the propeller section
Analisis Perpindahan Panas Pada Oven Pengering Berbahan Bakar LPG Untuk Proses Pengeringan Umbi Porang
No full textOven pengering merupakan salah satu alat alternatif yang digunakan untuk pengeringan suatu bahan makanan. Penggunaan alat ini sangat membantu dalam proses pengeringan karena tidak bergantung pada cuaca, mempercepat proses pengeringan dan juga dapat meminimalisir terkontaminasinya bahan makanan pada saat pengeringan dibandingkan dengan pengeringan menggunakan sinar matahari. Seperti pada pengeringan umbi porang di Desa Rejosari, Malang. Pengeringannya yang masih bergantung pada cuaca, dimana prosesnya bisa berhari-hari jika memasuki musim penghujan. Dibuatlah alat pengering umbi porang yang mempunyai tujuan agar bisa menjadi solusi untuk pengeringan umbi porang nantinya. Dari hal tersebut perlu dilakukan pengujian pengeringan umbi porang menggunakan oven pengering yang telah ada dengan temperatur 60 agar dapat mengetahui efisiensi yang dihasilkan oleh oven serta persentase pengurangan berat dari umbi porang.
Hasil yang didapatkan dari proses pengujian pengeringan umbi porang yaitu kerugian kalor pada dinding lemari pengering (Qloss DLP) sebesar 70,44705565 W, kalor yang digunakan untuk memanaskan oven (Qsensible) sebesar 2215,03W, kalor yang digunakan untuk menghilangkan kadar air pada umbi porang (Qevaporasi) sebesar 668,992W sehingga menghasilkan efisiensi lemari pengering sebesar 45,61% dan efisiensi plan keseluruhan sebesar 0,0209%. Pengujian ini dilakukan hingga 3kali dan menghasilkan persentase pengurangan berat umbi porang sebesar 82,9%.============================================================================================
A drying oven is an alternative tool used for drying food ingredients. This tool is very helpful for the drying process because it does not depend on the weather, speeds up the drying process, and can also minimize the contamination of food ingredients during drying compared to drying using sunlight. As in the drying of porang tubers in Rejosari Village, Malang. The drying is depending on the weather, where the process can take days if it enters the rainy season. A porang tuber dryer was made with the aim of being a solution for drying porang tubers on the future. From this statement, it is necessary to test the drying of porang tubers using an existing drying oven with a temperature of 60℃ in order to determine the efficiency produced by the oven and the percentage reduction in the weight of porang tubers.
The results obtained from the testing process for drying porang tubers are the heat loss on the drying cabinet wall (Qloss DLP) of 70.44705565 W, the heat used to heat the oven (Qsensible) of 2215.03W, the heat used to remove the moisture content of the porang tubers. (Qevaporation) of 668,992W resulting in a drying cabinet efficiency of 45.61% and an overall plan efficiency of 0.0209%. This testing was carried out up to 3 times and resulted in a percentage of porang tuber weight reduction of 82.9%
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
