ABSTRACT
By: ANDRIANSAH
This research aims to produce interactive video learning media on the
water cycle, determine the feasibility of learning media on the water
cycle, and determine students' understanding of the water cycle
material. This research is development research (Research and
Development), using the ADDIE research model which consists of five
steps, namely Analysis, Design, Development, Implementation, and
Evaluation. This water cycle learning media was validated by
material experts, media experts, and by practicing educators. The
water cycle learning media was tested in small groups and large
groups on class VI SD/MI students. Validation data and student
learning outcome level data on cognitive aspects were analyzed
quantitatively descriptively. Water cycle learning media is produced
through the stages of Analysis, Design, Development, Implementation
and Evaluation. According to media experts, the results of the
feasibility test for water cycle learning media obtained a final score of
4.3 in the very good category. According to material experts, they
obtained a final score of 4.4 in the very good category. According to
the assessment of learning practitioners, they obtained a final score of
4.43 in the very good category. Then in the small group trial they got
a score of 3.9 in the good category, and in the field trial they got a
score of 4.3 in the very good category. The results of student learning
regarding the water cycle material based on cognitive aspects
obtained an average score of 81.1.

Pada Main Engine Di Km. Vertikal”, Program Diploma IV, Teknika, Politeknik Ilmu Pelayaran Semarang. Pembimbing I : H. MUSTHOLIQ, MM, M.Mar.E dan Pembimbing II : MOHAMMAD
SAPTA HERIYAWAN, S.Kom., M.Si. Pelumasan c merupakan salah satu aspek yang harus diperhatikan mengingat
bahwa bila sampai terjadi suatu kelambatan dalam pelumasan atau pelumasan
yang tidak sempurna makan akan mengakibatkan kerusakan pada bagian-bagian
yang bergesekkan, rendahnya tekanan minyak lumas merupakan salah satu faktor
penyebab tidak sempurnanya pelumasan pada mesin. Guna pelumasan bagi
kinerja mesin induk yaitu untuk mengurangi gesekan antar komponen mesin
induk yang lain. Tujuan penelitian ini adalah untuk Untuk me n g e t a h u i d a n
menentukan penyebab dari menurunnya kinerja Lubricant Oil cooler pada main
engine di KM. Vertikal, Untuk mengidentifikasi dampak dari menurunnya kinerja
Lubricant Oil cooler pada main engine di KM. Vertikal, Untuk menemukan
solusi yang dilakukan untuk meningkatkan kerjadari Lubricant Oil cooler main
engine di KM. Vertikal. Penelitian ini dilaksanakan di KM. Vertikal, metode yang digunakan dalam
penelitian ini adalah metode Kualitatif dengan Teknik SHEL. Adapun responden
adalah KKM dan Masinis II, Pengambilan data dilakukan dengan menggunakan
observasi, wawancara, dokumentasi. Berdasarkan penelitian yang telah dilakukan ada beberapa faktor yang
menyebabkan kurang optimalnya lubrication oil cooler pada mesin induk yaitu
faktor mesin meliputi kerusakan pada gasket, faktor manusia yaitu kurangnya
pemahaman masinis tentang lo cooler, faktor metode pengoperasian dan
perawatan yaitu ketidaksesuain dalam melaksanakan PMS (Plan Maintenance
System) serta faktor lingkungan yaitu kotornya filter sea chest. Dampak yang
terjadi adalah menurunnya kinerja operasional mesin induk, kinerja lo cooler
menjadi tidak maksimal, meningkatnya suhu minyak lumas pada motor induk dan
naiknya pressure jacket cooling
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
