Abstract

Analytical chemistry is one of the chemical materials that is considered difficult by students. The application of multi-representational proximity in delivering analytical chemistry material can make it easier for students to understand the material. The purpose of research and development is to produce Instagram- and TikTok-based learning media products on qualitative analysis materials for class I and II cations with a multi-representational approach, testing the feasibility of learning media in the form of Instagram and TikTok learning content, and to find out the response of students to the learning media. This research uses ADDIE research and development design. The ADDIE development model consists of five stages, namely analysis, design, development, implementation, and evaluation. At the development stage, validation of media and material experts by lecturers of the chemistry department, State University of Malang, as well as teacher chemistry SMKN 7 Malang continued the readability test on 52 students of class XI Analytical Chemistry 1 and 2. The questionnaires used are quantitative, processed with a Likert scale. The results of this research and development are in the form of learning content on the qualitative analysis material of group I and II cations uploaded on Instagram and TikTok, with a “very decent” validation value in general display, receiving a percentage of 84%; in presenting the material, 84%, the “very feasible” category; and in the results of the questionnaire, student responses are classified as “very good,” with a percentage of 81%. Instagram- and TikTok-based learning media are very feasible to use, and students show that Instagram- and TikTok-based learning media are very interesting when coupled with explanations interspersed with songs, helping readers who have auditory properties, so that students understand, are interested, and have fun learning with digital methods.
