Inert gas adalah suatu gas atau campuran bermacam-macam gas yang dapat
mempertahankan kadar oksigen dalam prosentase rendah sehingga dapat mencegah
terjadinya ledakan atau kebakaran. Peraturan Internasional mengatur mengenai
persyaratan untuk kapal tanker dengan bobot mati diatas 20.000 ton harus
dilengkapi dengan sistem instalasi inert gas. Dimana fungsi Inert Gas Generator
tersebut salah satunya adalah bekerja menghilangkan atau mengurangi kadar
oksigen dalam tanki hingga batas aman sesuai titik aman dibawah 8%. Dari uraian
tersebut, masalah yang dapat disimpulkan adalah apa dampak yang ditimbulkan
oleh Inert Gas Generator yang tidak optimal adalah terhambatnya proses bongkar
muat dan meningkatnya resiko bahaya ledakan di dalam tanki muatan, sehingga
perlu perawatan dan perbaikan pada Inert Gas Generator yang sesuai dengan
manual book.
Penelitian ini dilaksanakan selama penulis melaksanakan praktek laut di
kapal MT. SPASTIGA milik perusahaan PT. SCORPA PRANEDYA selama dua
belas bulan. Sumber data yang diperoleh adalah data primer yang diperoleh
langsung dari tempat penelitian serta data sekunder yang diperoleh dari literaturliteratur
yang berkaitan dengan judul skripsi.
Hasil kerja yang diperoleh ini menunjukkan bahwa tidak optimalnya sistem
Inert Gas Generator disebabkan oleh beberapa faktor seperti: kurangnya prosedur
pengoperasian, kurangnya perawatan yang sesuai instruction manual book, dan
kualitas bahan bakar yang kurang baik.

Muhammad Haidar Bayu Aji, 2019, NIT: 52155774.T, "Optimizing Inert Gas
Generators to Support the Safety of the MT Loading and Unloading

Inert gas is a gas or mixture of various gases that can maintain oxygen
levels in a low percentage so that they can prevent explosions or fires. International
regulations stipulate that the requirements for tankers with a deadweight of more
than 20,000 tons must be equipped with a gas inert installation system. Where the
function of the Inert Gas Generator is one of them is to work to eliminate or reduce
oxygen levels in the tank to the safe limit according to the safe point below 8%.
From this description, the problem that can be concluded is what is not the optimal
impact of the Inert Gas Generator is the obstruction of the loading and unloading
process and the increased risk of explosion hazards in the cargo tank, so that
maintenance and repair of the Inert Gas Generator is in accordance with the manual
book.
This research was carried out as long as the authors carry out marine
practices on MT. SPASTIGA belongs to the PT. SCORPA PRANEDYA for twelve
months. Sources of data obtained are primary data obtained directly from the place
of research and secondary data obtained from the literature relating to the thesis
title.
The results of this work indicate that the inert gas generator system is not
optimal due to several factors such as: lack of operating procedures, lack of
maintenance according to the instruction manual book, and poor quality fuel

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
