The development of information and communication technology in the current era of globalization has a big influence on the world of research. Where research is an activity carried out by researchers of the object of discussion using methods that are appropriate to the scientific field, which obtains results with specific goals and intentions. It is proven by the number of universities in Indonesia competing to publish their research results, one of which is the Faculty of Computer Science which manages several scientific journal publication portals, namely the Journal of Information Technology and Computer Science (JTIIK) and the Journal of Information Technology and Computer Science Development (JPTIIK) . This portal serves as a place to publish research results from students or lecturers. In conducting research, researchers sometimes exchange information, debate or collaborate with other researchers. Although there are many platforms that provide a place to exchange information and knowledge in conducting research, the Faculty of Computer Science is deemed necessary to have a place to collaborate with fellow researchers which is certainly supported by the existing portal system for publishing scientific journals. In this study the authors designed a collaborative application research system that aims to establish communication between teachers, students or researchers at the Faculty of Computer Science. The author uses the Rapid Application Development (RAD) method which is implemented with the Codeigniter framework in the system development process. Then the white box and black box methods are tested to ensure the system runs properly as needed. Browser Compatibility Test which aims to ensure the system can run on multiple web browsers.
