Abstract

The design of e-Board was undertaken to meet the necessary of information between colleagues that nowadays has become more essential and vital especially in a team work that applying distributed asynchronous co-operative work system. In which, members of the team are distributed in time and space; therefore information should be well distributed to support the cooperative work between them. The research was applying analysis and design methodology. The analysis methodology was undertaken through literature study, current system observation, questionnaire survey to users to identify characteristics of the current and entailed information distribution media. The design methodology was undertaken through database, features, system, and screen layout design. Results of the research found that the information distribution media for team work which has applied distributed asynchronous co-operative work system should have the ability of private access for each member, better organization in information categorizing, structured information for task assignment, and supporting member's mobility. In conclusion, the application has been expected to help task assignment, distribution and organization of information in the distributed asynchronous co-operative work system to be easier and simpler.

Abstract

Rapid development of Information Technology causes information can access easier without space boundaries. Image is a form of information, which contains many information. Some image contains confidential information that cannot distribute to unauthorized persons. Therefore, image encryption application is create to encrypt part of image that has confidential information. The image encryption application is encrypt image by applying DES, Triple DES, and IDEA algorithms. The research was applying analysis and design methodology. The analysis methodology was undertaken through literature study and algorithm research and testing. The design methodology was undertaken through database, features, system, and screen layout design. Results of the research are image encryption application that can encrypt part of image and or all of image by applying three algorithms such as DES, Triple DES, and IDEA. This application is show comparation of these algorithms. In conclusion, method of encryption can apply to image, so that confidential information of the image can protect from unauthorized person.

Abstract

Sometimes we find difficulties in obtaining the necessary information as limited to place and time, as well as the media used. One example is limitations in obtaining the necessary information about facilities available at the nearby of Binus University campus. Based on this case, we propose information media providing facilities around Binus University campus that can be accessed anytime and anywhere using mobile web technology guided by Google maps. The features of Google maps can also help users locate the facility. The methodology used in this research is analysis and design. Results that can be obtained from this research is a mobile-web application that provides complete information about the environment around BINUS campus that can be accessed by students and the surrounding community. Using this application, BINUS students can obtain the necessary information about the campus environment easily and quickly.

Abstract

The purpose of this study is to study the application of redundancy principles by Richard Mayer on learning material used in class presentation. The principles are applied during the learning material development, using PowerPoint as the learning medium. The result of this study showes that the application of redundancy principle on learning material development provides positive result in helping students’understanding during teacher’s presentation.

Abstract

Topography is the science about the earth's surface and other objects such as planets, satellites, and asteroids. Topography is studied at school and is found quite difficult to understand because it requires imagination to understand the meaning of contour maps as well as the lines. To motivate students in learning topography,we design an learning application of interactive topographic map with 3D features using Augmented reality technology. In this research we implement analysis and design method. The result achieved is a learning topographic map application based on augmented reality. The conclusion that can be drawn is the teaching and learning of topography can be more interesting with 3D features so that students can more easily recognize the meaning of contour lines in a topographic map.

Abstract

The technology development affects people activites especially in this 20th century. Mobile phone ischanged into smartphone and travelling becomes a new lifestlye. A Tourism scheduler with a reminder is created from this research to fulfill the new trend of people lifestyle. The travelling data is stored in the system and some information such as the point of interest of an area, hotel, and transportation to reach the area are provided. Waterfall model becomes the method to build this system. Hence, an application that can create a trip for the user is completely built in Blackberry application system, consist of the trip information. The history feature provided in this application can be an advantange for the user to choose the new travelling destination. Moreover, the application has a good interface follow the eight golden rules and has a good performance that helps the tourists/users to create their own schedule and set the reminder for them.
