The population in this research is the entire class D in first semester student in Mathematics Education academic year of 2017/2018. The model used is the development model of Borg and Gall which includes: (1) analysis of the content standards, (2) the collection of references to interactive media, (3) the preparation of draft interactive media, and (4) creation of interactive media in the form of digital discs (CD). Interactive multimedia has produced score of good quality according to the assessment of the learning materi- al experts, media experts, and students of Class D academic year of 2017/2018, with an average score was 209.48 with maximum score of 260. The effectiveness toward students’ confidents on computer shows there, 73.81% of students feel able to get good grade s if learn- ing with computers, 57.14% of students feel very confident when starting to learn with computers, and 50% students learn to feel confi- dent with computers.

Introduction Aspects in learning mathematics are the most important skills in the process was stressed thinking. Students are trained to be able to develop the ability of logical thinking, analytical, systematic and consistent. To assist in the process of thinking, or animated images and can be used. In the planning of learning lecturer can enrich the material to be conveyed by taking several contextual examples that exist in the virtual world with the help of the inter- net. “Indonesian Educational Ministery [4]” released that all of schools have had ICT equipment especially computer and its network for increasing the competence of graduates’ purpose, either in the classroom or in the library and laboratories. The computer can be used as media in learning mathematics. The computer could pre- sent in the form of graphics and media audio video. Of course this adds an attraction for students in learning, so the boring presenta- tion on teaching lectures can be reduced. Mathematical logic and set is one of the objects in UAD mathe- matics education study programs who has its own difficulties. One of the material in mathematical logic and set is the students ask to determine the truth of a single statement, which is sometimes make the students confuse. So it is very necessary to use the media that could explain more real, as well as provide simulation- simulation to train and improve the understanding of the students. One of the ICT products that can be used in the learning process is Adobe Flash CS3 (formerly Macromedia Flash Professional 8). With this software not only makes a presentation of learning, but it can develop interactive learning where students are learning with display has been prepared. In this learning process, students will choose and goes step by step, starting from the opening, the point material to the evaluation question. Adobe Flash CS3 is one of the animation design software maker. “Deniz et al [3]” have declared this software is very popular and has been recognized sophistica- tion and completeness of facilities that are able to create animated design, making this software most widely used by computer de- signers. “Geisert et al [5]” have studied mathematics subject matter in curriculum not all can use computer media, but at least there is new alternative media to support learning mathematics. The use of computers helps teachers become more efficient in completing daily tasks. And more importantly, teachers will experience how computers help with better teaching. “Yin et al [8]” have discussed a concept that can connect between the development of computers and mathematics learning so that learning mathematics will feel more fun and students can master the subject matter easily. One of the ideas that can be applied is to utilize computer-based media in the process of learning mathemat- ics at school. Some of the above explanation makes researchers develop learn- ing media using Adobe Flash CS3 in mathematical logic and set courses. Furthermore, interactive multimedia is expected to im- prove students' self-confidence toward computer. 2. Method This research is research development (Research and Develop- ment). “Borg et al [2]” have stated development of the research method is the method of research used to produce a particular product and test the effectiveness of these products.
