Optimasi Rule Curve Operasi Waduk Pengga Dengan Algoritma Genetik
Full text linkWaduk Pengga adalah waduk yang difungsikan untuk pelayanan air bersih di wilayah Kabupaten Lombok Tengah bagian selatan dengan pasokan air irigasi yang dilayani seluas 3005 Ha dan untuk pembangkit tenaga mikrohidro dengan kapasitas 400 KW. Pada pedoman lepasan waduk berdasarkan rule curve yang ada sekarang, apabila di simulasi operasi waduk 11 tahun, maka terdapat kekurangan pemenuhan kebutuhan minimum atau tampungan waduk dibawah rule curve eksisting, untuk mencukupi kebutuhan air irigasi seluas 3005 ha tersebut. Dengan melakukan optimasi pengaturan rule curve yang baru diharapkan pemenuhan kebutuhan minimum ini dapat ditingkatkan. Salah satu metode optimasi untuk penyelesaian masalah tersebut adalah dengan menggunakan prosedur simulasi stokastik yakni algoritma genetik. Tujuan dari studi ini adalah untuk meningkatkan kinerja operasi waduk Pengga berdasarkan rule curve. Untuk meningkatkanya dibutuhkan optimasi dan sebagai penunjang proses optimasi maka dibutuhkan perangkat software yang sesuai yaitu program spreadsheet Excel dari Microsoft Office versi 2010. Program MS Excel 2010 adalah program spreadsheet yang terdiri dari lembar-lembar worksheet untuk tampilanya dan prosedur Macro dengan Visual Basic untuk mengontrol jalanya program. Hasil dari studi ini adalah debit aliran rendah (low flow) yang dibangkitkan dari data hujan dengan metode FJ Mock waduk Pengga selama 11 tahun menghasilkan rerata dari setiap tahun berkisar 0,884 m3/detik sampai 3,383 m3/detik. Rerata pemenuhan kebutuhan irigasi rule curve berdasarkan tahun basah, normal dan kering adalah 82,80%, 65,89% dan 59,96%. Sedangkan pemenuhan kebutuhan irigasi minimum rule curve berdasarkan tahun basah, normal dan kering adalah 55,45%, 31,55% dan 31,25%. Dengan hasil rule curve tersebut intensitas tanam tidak bisa terpenuhi 300% karena terdapat kekurangan di beberapa musim tanam sehingga intensitas tanam yang terpenuhi adalah 260%..

An empirical investigation of IT innovation implementation in higher education institutions in Indonesia
No full textThe innovation implementation in Higher Education Institutions (HEIs) is commonly
considered to be one of the key drivers of organizational success. Many empirical studies
showed that implementing innovation improves organizational productivity, which in
turn will enhance organizational performance. On one hand, the study on post-adoption
behaviour of innovation is still on the disagreement level among the information system (IS)
researchers and practitioners. Some researchers have argued that it is necessary to take a
multidimensional approach when classifying innovations. In relation to the implications of an
innovation, success and failure factors for innovations were not the same for all innovations
but instead depended on three aspects such as types of innovation, attributes of innovation
and consequences of innovation. In the context of the organization, many studies have been
focused on the industrial sectors. It has been rare that the studies conducted in the higher
education world in the developing countries in particular. Besides, the characteristics of the
organization among the sectors may be different, the developing countries may also have the
different contexts. Therefore, the theoretical, practical, and the contextual gaps mentioned
above are still interesting for the continuous studies. This research aimed to develop the
systematic approach by propose the model of IT innovation implementation in the context of
HEIs, means that the IT innovation that has been adopted by organization can be implemented
successfully through the systematic process which will improve the performance of the HEIs
and which in turn obtain possible benefits as consequence of IT implementation effectiveness.
This study adopted a quantitative approach where a survey research was deemed as the
most appropriate to achieve the research objectives. The respondents of the survey were
managerial staff and lecturers of the HEIs who were considered to be key informants among
the 850 HEIs and the sample was chosen by using a simple random sampling. A total of
171 valid responses from 91 HEIs in Indonesia were then analysed by employing the Partial
Least Squares - Structure Equation Modelling (PLS-SEM) techniques to generate and test
the measurement and structural models. The results of this study highlighted that the most
important factor contributing to IT innovation implementation Top Management Support
constitute the imperative variable on IT innovation effectiveness. Whereas the Managerial
Patience, Human Resources Availability, and Implementation Climate did not seem to affect
IT implementation effectiveness. Unfortunately, IT implementation effectiveness found
unexpected result, it was not having an influence towards the IT innovation effectiveness.
Besides, the results may contribute theoretically towards the development of the IT innovation
implementation success, it may also contribute practically around the research field, especially
from the HEIs perspectives in Indonesia
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
Evaluasi Usability pada Aplikasi Instagram Menggunakan Metode Usability Testing
Full text linkSocial media is one of the platforms that is often used by people to interact and communicate with one another. Instagram is a social media platform that allows users to post photos and videos online at high speed. This study uses the usability testing method. Usability is used to measure quality based on user experience when interacting and using applications. The calculation results of the System Usability Scale (SUS) involving 50 respondents showed a score of 77.6. From this score, it can be concluded that the interpretation of the approach based on the nature (Adjective) shows that the service belonging to the Instagram application is still included in the GOOD category.Sosial media menjadi salah satu platform yang sering digunakan oleh masyarakat untuk berinteraksi dan berkomunikasi antara satu dengan yang lain.

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
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
