Students need motivation in order to increase their interest and focus of students. One way to increase students' learning motivation is by presenting interesting learning media for students. Social media is an audio-visual platform that steals the attention of many people in various groups, especially children to teenagers. The method applied in this research is the systematic literature review (SLR) method. The SLR method is used to identify, review, evaluate and interpret all available studies in a subject area of interest to a phenomenon involving a particular related research question. In the Literature Review Study that has been described, it can be concluded that research on Creator Content in Social Media-Based Chemistry Learning Media can be carried out with various considerations of research results similar to the Multi-representation approach which can increase student motivation and learning outcomes.

Initial understanding is the ability to build early based on experience and knowledge possessed by using grammar that is still relevant to new knowledge. This study aims to explore the experience and knowledge of students to determine the initial understanding of the reaction rates topic. The method used is a questionnaire as a research instrument. In total, 100 students from SMA in Malang, East Java were selected using the purposive sampling method. From these questions, the types of questions are grouped based on alternative answers and sub-material questions and include 3 levels of representation, namely macroscopic, sub-microscopic, and symbolic. Then students' answers are presented and then the students' initial abilities are described following the answers given by students. In teaching and learning activities, students often encounter concepts of knowledge that are constructed independently by students so that when new knowledge is given, there are often differences in understanding or differences in concepts with actual information. The quantitative findings show that in general students' understanding of concepts is 'good', especially on the basic concepts of the reaction rate topic. However, in several sub-materials such as reaction orders, reaction order graphs, and chemical reaction equations in the reaction rate concept topic, there are still conceptual errors experienced by students so improvements and emphasis on concepts are needed in some of these sub-materials so the percentage of correct answers from students is greater from the previous.
