PENGEMBANGAN MULTIMEDIA INTERAKTIF BERBANTUAN APLIKASI MOBILE PADA MATA PELAJARAN KIMIA KELAS X SMA

Abstract

Abstract

The development of this interactive multimedia is carried out as an effort to solve student learning problems, namely students with limited resources, limited learning time, difficulties in visualizing concepts, and difficulties in observing and evaluating results. This research aims to produce interactive multimedia products assisted by mobile  applications in Chemistry Class X of high school that are valid and practical. This research uses a development method known as Research and Development (R&D) with a 4D development model, namely Define, Design, Development, and Disseminate. The validation stage is carried out by material expert validators and media expert validators. The results of the media validity assessment obtained an average score of 4.6 from the first media validator and 4.6 from the second media validator on the first day, as well as an average score of 5 from the two validators on the second day, all of which were classified as "Very Valid". Meanwhile, the results of the feasibility test with the material validator produced an average score of 5 with the category "Very Valid". Based on the results of the practicality test conducted on grade X students at SMA Negeri 2 Bayang, an average score of 4.9 was obtained which was categorized as "Very Practical". Based on the results of the validity test and practicality test, it can be concluded that this interactive multimedia product assisted by a mobile application  is "Very Feasible" to be used in Chemistry class X of high school, especially in electrolyte and non-electrolyte solution materials.
