Comparison Encryption of How to Work Caesar Cipher, Hill Cipher, Blowfish and Twofish
Full text linkSecurity is the level of confidentiality of data stored using cryptography. There are many ways you can do to improve security. In this study, the writer will use a method by encrypting the database with the Caesar Cipher Algorithm, Hill Cipher and Blowfish. Caesar Cipher, Hill Cipher and Blowfish are part of the symmetric algorithm, which means that the encryption and decryption process have the same key. The encryption and decryption process in Caesar Cipher, Hill Cipher and Blowfish Algorithms each has one key. algorithm encryption techniques using symmetric passwords have 2 types, namely block ciphers and stream ciphers. Caesar Cipher, Hill Cipher and Blowfish and Twofish Algorithms are the encryption of the block cipher that breaks or creates blocks to encrypt and obtain cipher text. Result in this paper In Caesar Cipher, it is carried out like 3 blocks of encryption. Whereas in Hill Cipher a word is divided into several blocks and each block is encrypted. In Blowfish, several iterations are performed to get the text cipher, the input is 64 bits of data that can be done as many as 16 iterations. In Twofish the input is 128 bits, in contrast to Blowfish which is only 64 bits, Twofish can also accept 256 bits long and do 16 iterations to get the cipher text. Twofish has stronger security than the 3 algorithms above, Twofish also takes up more memory and takes longer to encrypt
PELATIHAN PEMBUATAN DAN PENGELOLAAN WEBSITE SEBAGAI SARANA INFORMASI PADA MADRASAH TSANAWIYAH AL FATAH MANDIRI JAKARTA
Full text linkPengabdian masyarakat ini memberikan ide bahwa media berbasis internet dapat memudahkan organisasi melalui website. Sebuah situs web (sering pula disingkat menjadi situs saja, website atau site ) adalah sebutan bagi sekelompok halaman web ( web page ), yang umumnya merupakan bagian dari suatu nama domain ( domain name ) atau subdomain di World Wide Web (WWW) di Internet. Sebuah web page adalah dokumen yang ditulis dalam format HTML (Hyper Text Markup Language), yang hampir selalu bisa diakses melalui HTTP, yaitu protokol yang menyampaikan informasi dari server website untuk ditampilkan kepada para pemakai melalui web browser baik yang bersifat statis maupun dinamis yang membentuk satu rangkaian bangunan yang saling terkait dimana masing-masing dihubungkan dengan jaringan-jaringan halaman (hyperlink), harapan kami setelah adanya kegiatan Pengabdian Kepada Masyarakat mengenai sosialisasi “Pelatihan Pembuatan dan Pengeloaan Website Sebagai Sarana Informasi†di MTs Al Fatah Mandiri Jakarta, mereka dapat menerapkan pengetahuannya dalam aktivitas sehari-hari baik itu dalam kegiatan pembelajarn ataupun dalam kepentingan lainnya. lmu yang diperoleh pada Pengabdian Masyarakat kali ini diharapkan mampu memberikan semangat baru bagi kita dalam berbagi pengetahuan dan motivasi serta berkontribusi bagi generasi muda, baik dilingkungan sekolah, kampus dan keluarga
PENERAPAN METODE WEIGHTED PRODUCT PADA SISTEM PEMILIHAN GURU TERBAIK (STUDI KASUS : MADRASAH ALIYAH SWASTA ULUL ILMI JAKARTA)
Full text linkPada saat ini Madrasah Aliyah Swasta Ulul Ilmi Jakarta masih menggunakan cara lama dan biasa dalam penentuan Guru terbaik. Proses yang digunakan dalam menentukan guru terbaik menggunakan penghitungan sederhana dianggap kurang efektif, karena masih menggunakan perhitungan rata-rata yang diambil dari hasil pengamatan kelas, wawancara acak dan nilai kuesioner siswa yang dihitung menggunakan Microsoft Excel sehingga tidak sesuai dengan hasil akhir yang diharapkan oleh para guru. Untuk membantu mengatasi hal tersebut, dalam hal ini dipilihlah Metode WP (Weighted Product) yang digunakan untuk mengembangkan aplikasi seleksi guru terbaik. Metode ini digunakan karena menggunakan perhitungan bobot nilai yang sederhana. WP merupakan suatu metode yang menggunakan perkalian untuk menghubungkan rating atribut, dimana rating setiap atribut harus dipangkatkan dulu dengan bobot yang bersangkutan. Sistem informasi ini diharapkan dapat membantu dan mempermudah dalam proses seleksi guru terbaik di Madrasah Aliyah Swasta Ulul Ilmi Jakarta sehingga sesuai dengan hasil yang diharapkan
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
