Implementasi dan Pengukuran Kinerja Operasi Aritmatika Finite Field Berbasis Polinomial Biner
Full text linkCryptography is one of the security techniques that secure information confidentiality and information integrity while electronic transaction processing. There are three kinds of cryptograpy protocols, Symmetric Algorithms, Asymmetric (Public Key) Algorithms, and Cryptographic Protocols. Elliptic Curve Cryptography (ECC) is one of the public key encryption. ECC requires high computation for solving arithmetic operations.Finite field has important role in ECC implementation, which curve operations requires finite field. Finite field has several arithmetic operations, add, multiplication, squaring, and invers. There are many method or algorithm for each arithmetic operation. Finite field can be representation in prime field GF(p) and binary field GF(2m). There are two representation in binary field, polynomial basis and normal basis. This research presents implementation of arithmetic operation algorithms for adding, multiplication, squaring, and invers on polynomial basis with maximum key 299 bits. Besides that, this research presents the measurement of algorithm performance based on processing time and memory usage. Keywords — cryptography, elliptic curve, finite field, polynomial basis, binary fiel
Rancang Bangun Aplikasi E-Learning Berbasis Multiplatform untuk Mata Pelajaran Bahasa Indonesia dengan Menggunakan Pendekatan Technology Acceptance Model (TAM)
Full text linkIndonesian Language Lessons for 2nd grader of Elementary School with Standard of Competency 4 is the subject to discuss writing of short story with the correct words, capital words usage and the usage of correct full stop marker in the upright continued writing letters. The multiplatform application design is to seek solutions to problem learning method less attractive. This applications are operated in three operating systems, Windows, Android, and Ubuntu. This research employes approach of Technology Acceptance Model (TAM) by involving teachers and 2nd graders from Medalem II Public Elementary School in Tuban and Bangah 1 Public Elementary School in Sidoarjo. The data in research were colleted using questionnaires. In addition to using questionnaires, tests were conducted by giving Pre-Test and Post-Test that was, aimed at determininge the differences between the values obtained from the students before and after using the application. Keywords — E-Learning, Indonesian Language Lessons, Technology Acceptance Mode
Web Untuk Deteksi Dini Tingkat Retardasi Down Syndrome Pada Anak
Full text linkDown Syndrome is a condition of physical and mental development's retardation in children that caused by abnormalities in the development of the chromosome. However, behind the special needs held by children with Down syndrome, they have a chance to live like any other normal child.This study aims to create a web-base application that can assist parents to make early detection of the retardation level of Down Syndrome in children, as well as provide information about how to deal with Down Syndrome. One of the benefit of this application is to help parents who have Down syndromes children in order to make early treatment correctly. Other benefit for psychologist is to help them make notes about the progress of the Down syndromes patient. The results of the testing and evaluation declared that this web fit and feasible to detect the level of retardation in children with Down syndrome.Keywords: Down syndrome, detection, level of retardation, we
PEMBUATAN SISTEM AKADEMIK PADA SMA PGII DENGAN METODE SIMPLE ADDITIVE WEIGHTING (SAW)
Full text linkSenior high school of Persatuan Guru Islam Indonesia (senior high school of PGII) is one of the international schools located in the city of Bandung , West Java . PGII high school wants to develop an academic system .The academic system will be utilized by students and teacher to create the report of students values at the school. The main feature of this application is the recommendation for the student to represent a school. This recommendation was made using the Simple Additive Weighting (SAW) Method. SAW method is one Decision Support System (DSS) methods that uses a weighted sum of each alternative at every attributes.Keywords: academic system, SAW, senior high school
Perbandingan Metode-Metode Klasifikasi untuk Indoor Positioning System
Full text linkIndoor Positioning System can provide position and navigation guidances inside a building. This paper discusses about systematic comparison between K-Nearest Neigbors and Naïve Bayes Classifier over WiFi-based Indoor Position System dataset. The dataset is collected using a custom Android Application, which able to receive and record WiFi signal strengths from the surrounding WiFi hotspots in UKDW campus. The dataset consists of 11658 Received Signal Strength (RSS) data from 41 public locations in UKDW campus. We use 10-folds cross validation and T-Test with 0.05 significance level to compare classification accuracy between K-Nearest Neigbors and Naïve Bayes classifier. Based on the experiment result, we can conclude that K-Nearest Neighbors classifier produces better classification accuracy (83.58%) than Naïve Bayes (61.52%)
Prototipe Sistem Informasi Geografis Fasilitas Kesehatan di Kota Cirebon Berbasis Web
Full text linkIn the development of health need the data and information system that is integrated with both the development process so that health facilities can be optimized and the right target. One information system that can be used in the development of health facilities in the city of Cirebon is a geographic information system (GIS). And one of the software to build applications GIS is an Arcview and AlovMap. ArcView software is one of the software (tools) GIS and mapping was developed by ESRI (Environmental Systems Research Institute, Inc). ArcView has the ability to do data visualization, data exploration, the query (both spatial and non-database spatial), analyze the data geographically, and so forth. And AlovMap (including open source software) is a portable application WebGIS Java-based publication that is used to Raster and vector data on the Internet. Excess geographic information system facilities in the city of Cirebon AlovMap use is open source and are cheaper and have the ability to support the visualization of information in decision making. This system can produce a map of the output of these pharmacies, laboratories and hospitals. Utilization of GIS for health facilities that was built is extraordinary in integrating between science, technology and health. Keywords— Arcview, Alowmap, Geographic information system, Health of facilities, Overlay, Shortest path
Kombinasi Penggunaan Model Warna Dalam Pendeteksian Letak Bibir pada Gambar digital Berwarna
Full text linkDifferent color model has been used to detect the location of lips within color images. These color models have different advantages and weakness. This paper intends to compare several uses of color model (namely the rgb, normalized rbg, and the YCbCr color model that is used frequently on several lip localization technique) and try to propose a combination of color model to minimize post processing in lip localization. The proposed combination combines the normalized rgb color model, the YcbCr colod model and the intensity based rgb model to obtain lip area. The combination proved to provide better distinction with only slighty more calculation
