Kombinasi Algoritma AES, RC4 dan Elgamal dalam Skema Kriptografi Hybrid untuk Keamanan Data
No full textDelivery or exchange of data is something that often happens in the world of information technology. Data sent sometimes often contain important information data even highly confidential and must be safeguarded. To maintain data security, can be done using cryptographic techniques. The data security techniques layered security with a combination of symmetric cryptographic algorithm Advanced Encryption Standard ( AES ) with RC4 by applying the hybrid scheme, where data is encrypted with a symmetric algorithm while the key is encrypted using a symmetric algorithm asymmetric algorithm or a public key algorithm. Symmetric algorithm is an algorithm of encryption and decryption using the same key. For the security of symmetric keys is done by using a public key algorithm ElGamal .Pengiriman atau pertukaran data adalah hal yang sering terjadi dalam dunia teknologi informasi. Data yang dikirim kadang sering berisi data informasi yang penting bahkan sangat rahasia dan harus dijaga keamanannya. Untuk menjaga keamanan data, dapat dilakukan dengan menggunakan teknik kriptografi. Teknik keamanan data dilakukan pengamanan berlapis dengan melakukan kombinasi algoritma kriptografi simetri Advanced Encryption Standard (AES) dengan RC4 dengan menerapkan skema hybrid, dimana data dienkripsi dengan algoritma simetri sedangkan kunci algoritma simetri dienkripsi menggunakan algoritma asimetri atau algoritma kunci publik. Algoritma simetri merupakan algoritma enkripsi dan dekripsi menggunakan kunci yang sama. Untuk pengamanan kunci simetri dilakukan dengan menggunakan algoritma kunci publik Elgamal.160 HalamanTesis Magiste
JARINGAN SYARAF TIRUAN BACKPROPAGATION UNTUK ANALISIS JUMLAH PENDUDUK MENURUT JENIS KELAMIN PADA KABUPATEN ASAHAN
No full textDalam kehidupan ekonomi jumlah penduduk berpengaruh dan memiliki peran yang sangat penting. Dengan banyaknya jumlah penduduk akan butuh konsumsi yang besar sehingga butuh produksi yang besar juga dan akibatnya kegiatan ekonomi akan berjalan serta akan cepat berkembang sehingga terjadi pertumbuhan ekonomi. Pertumbuhan penduduk Kabupaten Asahan berdasarkan data BPS mulai tahun 2010-2020 terus mengalami peningkatan. Tujuan penelitian ini menganalisis pertumbuhan penduduk menurut kecamatan yang ada di Kabupaten Asahan menggunakan Jaringan Syaraf Tiruan Model Backpropagation. Pada penelitian ini arsitektur JST yang dirancang diperoleh dari hasil trial dan error menggunakan aplikasi Matlab R2015A. Ada 5 model arsitektur yang dipilih yaitu 3-10-1, 3-15-1, 3-20-1, 3-25-1, 3-30-1 dan dari 5 model tersebut didapat arsitektur jaringan terbaik yaitu 3-15-1 dengan validasi R=0,99867. Proses training menghasilkan iterasi (epoch) sebesar 2691 dengan waktu 00:05 detik. Hasil validasi dan akurasi training yang didapat menggunakan MSE sebesar 0,000053206 dan akurasi testing sebesar 0,000118289. Kata kunci: Jumlah penduduk, Asahan, JST, Backpropagation, Matla
Kombinasi Algoritma Simetri dan ECC untuk Meningkatkan Keamanan Pesan
No full textPengiriman atau pertukaran data adalah hal yang sering terjadi dalam dunia teknologi informasi. Apalagi pengiriman data dilakukan melalui layanan komunikasi dunia maya, ancaman kejahatan sangat banyak terjadi didalamnya. Untuk menjaga keamanan data, dapat dilakukan dengan menggunakan teknik kriptografi.Banyak algoritma kriptografi yang digunakan untuk melakukan pengamankan pesan, tetapi kekuatan dari keamanan pesan tersebut masih lemah. Peningkatan keamanan pesan dan kunci dilakukan dengan algoritma hybrid. Metode hybrid dilakukan dengan mengkombinasikan algoritma simetri AES dengan OTP dengan algoritma ECC (Elliptic Curve Cryptograpy) yaitu ECDH (Elliptic Curve Diffie-Hellman). Algoritma AES dan OTP digunakan untuk enkripsi dan dekripsi pesan sedangkan ECDH digunakan untuk menentukan dan pertukaran kunci nya sehingga akan semakin meningkatkan keamanan dari pesan
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
Sistem Pendukung Keputusan Dalam Menentukan Pengguna Listrik Subsidi Dan Nonsubsidi Menggunakan Metode Fuzzy Mamdani (Studi Kasus : PT. PLN Tanjung Balai)
Full text linkAbstract - The electricity subsidy program is one of the poverty reduction programs by providing electricity subsidies to poor and disadvantaged households paid by the Government of Indonesia to PT. PLN (Persero). At PT. PLN (Persero) Area Rantau Prapat Rayon Tanjung Balai which is located on Jl. General Sudirman has a problem that is faced, namely regarding the subsidy budget, it turns out that there have been many wrong targets, most of the subsidy funds have fallen to economically capable people. The government applies the electricity subsidy policy on target, subsidies must be really enjoyed by poor people. To provide electricity subsidies to poor households and poor households, both humans and agencies cannot be separated from information technology systems. This system is usually called a decision support system that is designed to assist in making a decision where no one knows exactly how the decision should be made. The problem of decision-making systems using fuzzy logic systems is very suitable for definite reasoning or estimation, especially for systems with difficult mathematical models and inappropriate data to get a definite decision.

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
