Abstract

The utilization of e-learning can improve effectiveness and flexibility of learning. One important activities e-learning feature is a discussion forum. Communication between educators and students in class will be more effective if combined with communication through a discussion forum. Binus Online Learning is selected as a place of research. Binus Online Learning is a program of Bina Nusantara University that offers online study activities, which most of the students are invited to have self study activities. The aim of this research is to do requirement analysis and then to design a forum discussion called M-learning for Binus Online Learning so that it will be beneficial for the students that they can easily use the faster access. In this research, used are data collection through surveis, and analysis based on are literature study and the current systems, while rich picture and user interface are used for design. The results obtained are some features for the mobile learning discussion forum.

Abstract

Technically registration form for new Binus institution must be regenerated and not dynamic. Therefore, this research is objected to simplify the creation of registration process for new Binus institution and provide solutions to the problem when Binus establish other new institutions. Methodology used is analysis and design of the database (database oriented). Analysis is done by asking the problems of existing systems in the IT Directorate, whereas the design uses UML diagram notation 2.0. The results obtained is front end and back end applications for the Content Management System of the registration form. The results of this design can be used to simplify the new student registration or in the many Binus institutions by grouping similar fields. With some changes in the front end and back end applications for content Management System, the addition of new online admission application form can be managed faster, where the creation of admision registration form is managed in the back end application. As suggestions for future development, online admission registration can be run in mobile version.

Abstract

For each company, disasters may have diverse impacts either financially or non-financially. Therefore, a company requires a business continuity plan. One important factor in developing such plan is Business Impact Analysis (BIA). With BIA, a company can identify and analyze Critical Business Functions (CBFs) and potential impacts on the business whether operationally or financially, and further, business recovery priority, strategy and solution can be determined following a disaster.Methodologies used in developing this BIA are quantitativeand qualitative where for aspects related to financials, quantitive method is used. Meanwhile, for those aspects\ related to non-financial areas, qualitative method is used. The development of this BIA was done through the dissemination of questionnaires to 62 business units in PT Bank XYZ. To draw the BIA, eight parameters were used, where as for the final result, there were three criticality levels found in the business units of PT Bank XYZ, i.e. very critical level - 18 business units (29%), critical level - 23 business units (37%) and less critical level – 21 business units (34%). In addition, there were 71 applications used by CBFs. Based on the results of this study, PT Bank XYZ can determine the priority and key strategies for business units that require handling and recovery when a disaster occurs to maintain the bank's business operation's continuity and sustainability.Withthat, the company can minimize the potential loss resulted from a disaster.

Abstract

Nowadays a lot of school would like to be a digital school or e-school. They may face lot of problems due to the sudden transition from conventional school to digitalized school. Some major problems are both lacks of human resources or man power and the basic knowledge about technology itself. Based on survey, the most common problem faced by most school is insecure wireless network. Even though they already installed advanced hardware, network security is still be the basic problem. No security mechanism such as encryption and authentication is the most common problem that may cause their network very vulnerable with any possible threat. After doing the research, Radius Server (both for authentication server and monitoring system) can help solve the problem.

Abstract

Investigating and rethinking process in academic world influenced the architectural design culture. Affordable supporting digital tools lead the unlimited exploration into new ideas and possibilities. Heliodon is one of the tools to represent the sun mobility that helps analyze architectural form finding process. The Sun evolution and revolution are mapped into a computerized framework. With this framework, vendors and research group can develope its capability to create a powerful exploration tool. This opportunity gives a redefined meaning of the design process where all information is exchanged digitally. This study discusses some applications such as Google Sketch Up, Rhino ceros with its Grasshopper plug-in, and Graphisoft ArchiCAD which record physical data of climatic factors, The aim of this paper is to describe how sun study in digital tools redefines the architectural design process.
