Implementasi Algoritma C 5.0 untuk Identifikasi Pola Transaksi Penjualan: (Studi Kasus: Basnul Café)
Full text linkBasnul Café is one of the cafes located in the Ringroad Sunggal area of Medan. The fierce competition in the business world has led many cafes to continuously innovate their menus to attract customers, especially the younger demographic, due to declining product sales. Basnul Café aims to develop innovations in its food and beverage menu to increase sales. Previously, sales transaction data at Basnul Café were only stored as archives. To address the issues faced by Basnul Café, the author strives to identify transaction patterns to boost product sales using the C5.0 algorithm, which is part of data mining that processes information through classification methods. This is achieved by forming a decision tree to generate new rules. The formation of the root in the decision tree is based on the calculation of information value and gain used to divide groups according to their respective classes. From the findings of this study, it can be concluded that the C5.0 algorithm can predict the menu class according to recommendations or non-recommendations. In addition, this algorithm provides support to the cafe in making strategic decisions related to its products
IMPLEMENTASI KRIPTOGRAFI VIGENERE CIPHER DENGAN PHP
Full text linkAbstract - This research was conducted to create a cryptographic implementation of vigenere ciphers. This system is designed by analyzing the descriptive method, and the comparative method. After analysis, modeling is done with UML (Unified Modeling Language) and the design of vigenere cipher cryptography system with text encryption and decryption can be programmed using PHP software. The results of this study are an implementation of the vigenere cipher cryptographic system with PHP. Keywords - Cryptography, Vigenere Cipher, Encryption - Decryption, Text, PHP
ANALISIS SISTEM ARSIP DI KANTOR REGIONAL SEKRETARIAT PEMERINTAH KABUPATEN BATU BARA
Full text linkAbstract - This research is done because the processing of archiving is still done manually, this is very difficult and slow in searching if needed. Archiving a few months or even years ago will certainly be difficult to find because of the accumulation of files or because the archive has been damaged. The difficulty and complexity can be overcome by using WEB-based and MySql databases to manage archives. Management utilizing WEB-based and MySql databases are no longer in the form of archive sheets but have been in the form of scanned files from the original archive. The scanned archive will be stored with certain codes to make it easier to search so that the archives that came in a few months or even years ago are undamaged and easy to find. Keywords - Archiving, Analysis, The Batu Bara Regenc
Sistem Pendukung Keputusan Menentukan Matakuliah Pilihan pada Kurikulum Berbasis KKNI Menggunakan Metode Fuzzy Sugeno
Full text linkPengambilan Keputusan merupakan proses pemilihan alternatif tindakan untuk mencapai tujuan atau sasaran tertentu. Pengambilan keputusan menentukan matakuliah pilihan pada kurikulum berbasis kkni dilakukan dengan pendekatan sistematis terhadap permasalahan melalui proses pengumpulan data menjadi informasi serta ditambah dengan faktor-faktor yang perlu dipertimbangkan dalam pengambilan keputusan. Pada suatu proses pengambilan keputusan, para pengambil keputusan seringkali dihadapkan pada berbagai masalah yang bersumber dari beragamnya kriteria. Sebagai contoh praktis, menentukan matakuliah pilihan berbasis KKNI sering menghadapi kesulitan dalam menentukan prioritas dalam proses pengambilan keputusan dan kebijakan terhadap pemilihan matakuliah. Sehingga sistem pendukung keputusan dapat digunakan oleh mahasiswa dalam proses pengambilan keputusan, dipadukan dengan metode Fuzzy Sugeno didalam sistem tersebut, maka keduanya dapat saling berintegrasi, sehingga mampu menyelesaikan masalah tersebut.Kata kunci : Fuzzy Sugeno, SPK, Matakuliah Pilihan, Kurikulum Berbasis KKN
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
IMPLEMENTASI LOGIKA FUZZY DALAM MENENTUKAN JURUSAN BAGI SISWA BARU SEKOLAH MENENGAH KEJURUAN (SMK) NEGERI 1 AIR PUTIH
No full textAbstract - The process of selecting majors by prospective students by SMK Negeri 1 Air Putih is done manually. There are students who feel they are not compatible with their interests when getting lessons at school, this results students change schools and some drop out of school. Other things that can also have an effect such as students who move and dropout. In this study a system for implementing fuzzy logic was built using the method Tsukamoto. From the results of the research, the results of the Tsukamoto method were able to provide departmental recommendations which matches the subject that has high grades. Keywords - Fuzzy Tsukamoto, Fuzzy Logic, Prospective New Students.Â
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
