Abstract

Taking the test card is part of the academic system Institut Science & Technology AKPRIND Yogyakarta and is an activity that is always done when the student before the exam. Examination card retrieval system that runs for this still use conventional system. This method is still less effective because students have to queue for a long time and also have to come to the campus directly. The proposed system research aims to facilitate students in the process of taking exam cards. System that will be developed web-based (web based), so that this system can be accessed online using both computer and smartphone devices. Research on the online card retrieval system was developed using Codeigniter (CI), one of the framework used to build a website. The development of web-based applications, CI framework has a very fast performance, easy configuration and complete documentation. This research uses waterfall diagram as research method and MySQL as database processing. Testing system conducted in this study by using black box testing method and testing the questionnaire. Black box testing aims to obtain a set of input conditions that will fully implement all the functional requirements of a program. This test concluded that the built application system can function as expected. While testing the questionnaire is done to know user acceptance or user satisfaction to the quality of the system developed. The results of the questionnaire test showed 80.24% of 82 respondents stated strongly agree that with the Online Card Exam Taking System Using Framework Codeigniter can help and provide convenience for students in the process of taking the test card.

Abstract

Advances in technology have made communication and information technology functions into convergent and known as ICT (Information and Communication Technology). Internet and smart devices have an important role as a medium for multimedia convergence at this time. Mobile communications technology also developed rapidly, as well as the development of features that support services in the GSM system, among others, is MMS (Multimedia Messaging Service) that allows data transmission such as images, audio, and video.Computational complexity becomes an important concern in the development of cryptographic techniques on smart devices in the limited of bandwidth on wireless networks, also limited processing, memory, and time. This paper will discuss the security of image message using the concept of super encryption to optimize security of encryption key that adopts the concept of steganography method called End Of File (EOF). Applications built able to combine the speed, security, and flexibility so as to produce a good combination of speed, high security, complexity, reasonable computational overhead, and computational power.Image encryption algorithm is successfully implemented on a smart device with Android based operating system. Application also has the fastprocess and efficient computing resource. These are evidenced by the average time of encryption for image size of 256 x 256 pixels at 0.75 seconds and the image with a size of 480 x 640 pixels at 2.09 seconds. Average time decryption to image size of 256 x 256 pixels by 0.58 seconds and the image with a size of 480 x 640 pixels of 1.66 seconds.

Abstract

Design cross section of wind turbine blades with airfoil cross-section can be made from a mathematical approach. The mathematical formula was discussed for airfoil shape from Joukowsky equation, that was developed by Nikolai Zhukovsky Egorovich. The problems would appear if used the Joukowsky equation settlement for design with manual, it could take a long time. The problem solving for the mathematical could use graphic user interfaces (GUI) program and the design for implementation could use computer aided design (CAD) program. The Joukowsky transformation was performed by conformal mapping through the transformation of a complex function from one coordinate system to another, which circle shape was transformed to airfoil shape. Ideal airfoil shape was obtained with observed of the transformation radius and center of the circle.
