Abstract

This study discusses specifically the encryption mechanism that maintains the integrity of the game data on online games. The purpose of this study is to implement symmetric key encryption and checksum for score calculation. There are two methods conducted in this study: analysis and design. The analysis method isperformed in two ways: analysis of existing systems and analysis of literature study. System design method used is prototyping. The results obtained are implemented on online game competition ‘Expedisi Indosat’ through Facebook from 3 – 30 July 2011. The implementation of symmetric key encryption mechanism and the checksum is useful to maintain data integrity on games especially the results score when the game is running and when there is data transmission from the client to the server.

Abstract

The research wanted to find the workflow and solution by developing m-learning object for Android and iOS-based smartphone and tablet that supported interactive multimedia. The research began with analysis, design, implementation, and evaluation. Currently, the learning objects were not compatible with mobile devices. To overcome this problem, the research focused on designing the instructional design for m-learning and the development of interactive multimedia. Instructional design was created by the collaboration of the subject matter expert and instructional designer. M-learning was designed using UML and developed using Adobe AIR technology. The implementation of this research was a prototype of m-learning for concept of cost in Faculty of Economics, Bina Nusantara University. Then, the evaluation was conducted by distributing m-learning object to 32 selected students by simple random sampling in their first week of lectures in February 2014. The observation was conducted during m-learning object installation and initial learning process. At the end of the second week of the experiment, summative assessment and questionnaire were given to students. The results show that m-learning object is compatible with mobile devices. The students also say that m-learning is easy to use and helpful for their learning.

Abstract

The purpose of this research is to design a database system that is implemented in a web-based academic management that can be used to support the information system and academic management at Muhammadiyah 4 High School Bandung. The proposed Method in system design includes 2 parts, such as system analysis and product design. Analytical methods include literature studies, interviews, and questionnaire. Meanwhile, the database design method used are three stages database design according to Connoly and Begg. The results achieved are web based academic and database management system at Muhammadiyah High School 4 Bandung. The conclusion obtained from this research is the system is able to provide information needs, faster, accurate, prevent duplication problem of data , to support decision making, to improve effective communication between the user, and to get the information easier.

Abstract

Learning Object (LO) is a representation of interactive content that are used to enrich e-learning activities. The goals of this case study were to evaluate accessibility and compatibility factors from learning objects that were produced by using BINUS E-learning Authoring Tool. Data were compiled by using experiment to 30 learning objects by using stratified random sampling from seven faculties in undergraduate program. Data were analyzed using accessibility and compatibility tests based on Web Content Accessibility Guidelines 2.0 Level A. Results of the analysis for accessibility and compatibility tests of Learning Objects was 90% better than average. The result shows that learning objects is fully compatible with major web browser. This paper also presents five accessibility problems found during the test and provide recommendation to overcome the related problems. It can be concluded that the learning objects that were produced using BINUS E-learning Authoring Tool have a high compatibility, with minor accessibility problems. Learning objects with a good accessibility and compatibility will be beneficial to all learner with or without disabilities during their learning process.
