Online discussion is an effective and an efficient means to replace the conventional discussion. Many organizations, communities and institutions participate in developing and using online discussion forums as a place to provide and exchange information and knowledge. Department of Information Technology Muhammadiyah University of Yogyakarta is using online discussion also. Information Technology of Muhammadiyah University of Yogyakarta has had a discussion forum using a Learning Management System (LMS). However it still has a weakness, website for discussion is divided into class years and courses taken, thus, not all students could discuss in one forum or website. This website was developed to accommodate all students so that they can discuss in one forum. In its development, the topics and subtopics not only are taken by the courses but also are selected by the students interest at the time. Also, the addition "Insert Coding" feature is suitable for students of Information Technology. This website was created using waterfall method with multiple stages, i.e. Analysis, Design, Coding and Testing. Thus, the construction of the system will be directed. From the test results, the website was successfully built and there are no bugs. By the website's online discussion, students, alumni and lecturers can more actively exchange the information and discuss some issues.
