EFEKTIFITAS REMEDIAL WORK PROJECT DALAM MENURUNKAN RISIKO KEGAGALAN BENDUNGAN (Studi Kasus Pada Kegiatan Remedial 8 Bendungan di Kabupaten Dompu & Kabupaten Bima NTB)
Full text linkABSTRAK
Remedial work project (RWP) adalah suatu proyek konstruksi yang bertujuan untuk
merehabilitasi bendungan yang terdiri dari perencanaan dan pemeliharaan serta pemantauan untuk
mengurangi resiko kegagalan bendungan. Penelitian ini bertujuan untuk menganalisis
implementasi remedial work project (RWP) pada Bendungan Jambu, Bendungan Lanangga,
Bendungan Sanggupasante, Bendungan Kesi, Bendungan Woro, Bendungan Tolotangga,
Bendungan Paradokanca, dan Bendungan Sumi dari penurunan resiko kegagalan bendungan.
Efektifitas resiko kegagalan bendungan dapat diketahui dengan membandingkan tingkat resiko
eksisting bendungan dengan tingkat resiko setelah dilakukan remedial work project (RWP). Dalam
penelitian ini, metode yang digunakan dalam penilaian tingkat resiko menggunakan metode
modifikasi ICOLD. Pada metode modifikasi ICOLD, penilaian tidak hanya fokus pada
karakteristik bendungan saja melainkan tentang analisis evakuasi, kerusahan di hulu dan hilir, serta
resiko kegagalan bendungan. Hasil analisa efektifitas akan dihubungkan dengan anggaran yang
diberikan terhadap masing-masing bendungan yang kemudian selanjutnya di uji tingkat
sensitifitasnya terhadap penurunan resiko. Penyebaran kuesioner juga dilakukan dalam penelitian
ini yang bertujuan untuk mengetahui tingkat penilaian dari tenaga ahli terhadap implementasi
operasi dan pemeliharaan bendungan. Hasil penelitian ini menunjukkan bahwa remedial work
project (RWP) sangat efektif dalam menurunkan resiko kegagalan bendungan dengan rata-rata
presentasi penurunan sebesar 24,58%. Alokasi anggaran yang diberikan di setiap bendungan
berbeda-beda karena karakteristik setiap bendungan berbeda-beda pula. Analisis sensitifitas
menunjukkan bahwa semakin besar anggaran yang diberikan, maka semakin rendah tingkat resiko
sehingga dapat diartikan bahwa jumlah anggaran yang diberikan sangat berpengaruh dalam
menurunkan resiko bendungan. Pada analisis kuesioner dilakukan uji validasi yang menunjukkan
bahwa nilai Rhitung > Rtabel, artinya kuesioner yang digunakan dalam penelitian ini dianggap valid.
Dan uji reliabilitas menunjukkan nilai cronbach’s alpha > 0.70 , artinya tingkat pengukuran dalam
kuesioner yang disebar memiliki konsistensi yang tinggi.

ABSTRAK
Remedial work project (RWP) is a construction project that aims to rehabilitate a dam
which consists of planning, maintenance and monitoring to reduce the risk of dam failure. This
research aims to analyze the implementation of the remedial work project (RWP) at Jambu Dam,
Lanangga Dam, Sanggupasante Dam, Kesi Dam, Woro Dam, Tolotangga Dam, Paradokanca
Dam, and Sumi Dam in order to reduce the risk of dam failure. The effectiveness of the risk of dam
failure can be determined by comparing the existing risk level of the dam with the risk level after
the remedial work project (RWP) has been carried out. In this research, the method used to assess
the level of risk uses the modified ICOLD method. In the ICOLD modification method, the
assessment does not only focus on dam characteristics but also on evacuation analysis, upstream
and downstream damage, and the risk of dam failure. The results of the effectiveness analysis will
be linked to the budget allocated to each dam which will then be tested for its level of sensitivity to
risk reduction. Questionnaires were also distributed in this research which aimed to determine the
level of assessment of experts regarding the implementation of dam operations and maintenance.
The results of this research show that the remedial work project (RWP) is very effective in
reducing the risk of dam failure with an average reduction percentage of 24.58%. The budget
allocation given to each dam is different because the characteristics of each dam are different.
Sensitivity analysis shows that the larger the budget provided, the lower the level of risk, so it can
be interpreted that the amount of budget provided is very influential in reducing dam risk. In the
questionnaire analysis, a validation test was carried out which showed that the value of Rcount >
Rtable, meaning that the questionnaire used in this research was considered valid. And the
reliability test shows that the Cronbach's alpha value is > 0.70, meaning that the level of
measurement in the questionnaire distributed has high consistency.

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
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
