PENERAPAN HIMPUNAN DOMINASI PADA GRAF UNTUK OPTIMALISASI PEMBOCORAN PIPA AIR MINUM DI KELURAHAN KALABAHI BARAT
Full text linkPerkembangan penduduk yang sangat tinggi berdampak lurus pada kebutuhan air minum di wilayah Kelurahan Kalabahi Barat. Hal ini memicu persaingan antar masyarakat dalam usaha memperoleh air minum, yaitu dengan membocorkan pipa air minum yang melewati rumah masyarakat tanpa saling mempedulikan. Penelitian ini bertujuan untuk mengoptimalkan pembocoran pipa air minum pada jaringan perpipaan di wilayah Kelurahan Kalabahi Barat dengan menerapkan himpunan dominasi pada graf. Jaringan perpipaan yang digunakan sesuai kondisi sebenarnya, kemudian diterapkan ke dalam bentuk graf selanjutnya mencari himpunan dominasi untuk memperoleh simpul dominasi minimum. Hasil penelitian ini berupa total titik pembocoran pipa air minum yang optimum, yaitu dari sebelumnya total titik pembocoran adalah 276 titik yang mendominasi 536 buah rumah dan setelah menerapkan himpunan dominasi total titik pembocoran berkurang menjadi 177 titik yang mendominasi 536 buah rumah di Kelurahan Kalabahi Barat.

Penerapan Konsep Himpunan Dominasi pada Teori Graf untuk Optimalisasi Jumlah Kebocoran Pipa Air Minum di Desa Mausamang, Kabupaten Alor
Full text linkRegional development is one of the problems that are often faced by PDAM. The development of the area is the development of a water pipe distribution network. The more people there are, the more people will find it difficult to get optimal drinking water because they leak it without thinking about other peoples. As an example of the problem of regional development, there are several areas that have not received water from PDAM, this shows that the distribution of clean water isn’t optimal. In an effort to overcome these problems, an action is needed to optimize the pipe leaks. The purpose of this study is to minimize the leaks of the primary pipe by using the concept of applying the domination set of graph theory. The research steps carried out by researchers include data collection, determining the domination set, and distribution of drinking water pipelines. The comparison of the total initial primary pipe leaks points is 80 points that dominate 117 house points and by minimizing the primary pipe leaks by applying the concept of the domination set to 44 points that dominate 117 house points there is a reduction of 36 primary pipe leaks points that will be closed. The data concludes that the concept of the domination set on the graph can be used to find the optimal network in the PDAM water distribution network.Pengembangan wilayah merupakan salah satu permasalahan yang sering dihadapi oleh PDAM. Pengembangan wilayah yang dimaksud adalah pengembangan jaringan distribusi pipa air. Semakin banyak penduduk maka semakin banyak juga warga yang sulit mendapatkan air minum yang optimal karena mereka membocorkan tanpa memikirkan warga lain. Sebagai contoh masalah pengembangan wilayah tersebut ada beberapa daerah yang belum teraliri air dari PDAM, hal ini menunjukkan bahwa pendistribusian air bersih masih belum optimal. Dalam upaya mengatasi permasalahan tersebut diperlukan suatu tindakan untuk mengoptimalkan kebocoran pipa tersebut. Tujuan dari penelitian ini adalah untuk meminumkan kebocoran pipa primer dengan menggunakan konsep penerapan hiimpunan dominasi pada teori graf. Langkah-langkah penelitian yang dilakukan oleh peneliti meliputi pengambilan data, menentukan himpunan dominasi, dan pembagian jalur perpipaan air minum. Perbandingan total titik kebocoran pipa primer awal yaitu 80 titik yang mendominasi 117 titik rumah dan dengan meminimumkan kebocoran pipa primer tersebut dengan menerapkan konsep himpunan dominasi menjadi 44 titik yang mendominasi 117 titik rumah terdapat pengurangan 36 titk kebocoran pipa primer yang akan di tutup. Data tersebut menyimpulkan bahwa konsep himpunan dominasi pada graf dapat digunakan untuk mencari jaringan optimal pada jaringan distribusi air PDAM
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
