Aplikasi Mobile Pengenalan Tata Surya dan Galaksi Bimasakti Menggunakan Multimedia Development Life Cycle

- SDN Duri Kepa 16 Pagi is one of the elementary schools. Currently, students at the school involve direct interaction activities between teachers and students, and use reading book learning media. Students' interest in recognizing natural knowledge about the Earth's universe located in the Solar System & Milky Way Galaxy is still not massively applied in the learning process, from the process of these activities students prefer to play with technology rather than reading from textbooks. Therefore, the importance of learning the knowledge of the universe about the Milky Way galaxy, especially for early childhood. They needs special attention because it is related to the early development of children. This research uses the Multimedia Development Life Cycle (MDLC) method, this MDLC will be useful for the cycle of building game scenarios and the steps of building multimedia-based mobile applications. The results of blackbox testing research have been carried out, resulting in direct application testing with users, namely teachers and students, and the test runs well without any errors in the application. As for the results of testing with System Usability Testing (SUS), the final score obtained is 84.8 with the results of the percentage of proximity to the target, namely the achievement of Excellent. From the activities of the research series above, that the mobile application for the introduction of the solar system & Milky Way galaxy can be used by students as a means of fun learning media to attract interest and increase the general knowledge of students in elementary schools, and is useful for teachers in developing information technology-based learning media.
