The motivation of SMK Cendekia Madiun students to learn trigonometry is quite low. Therefore, the ITS and the UNIPMA teams conduct a community service at SMK Cendekia Madiun. The results of community service show that the visualization of trigonometric concepts can increase student's learning motivation. Another result of this community service is that students are able to think visually. This paper discusses the students' visual thinking scheme in understanding trigonometric concepts that are obtained based on the results of descriptive exploratory research using a qualitative approach. Data was collected using questionnaires and semi-structured interviews. In-depth interviews were also conducted to obtain saturated data. Data validation is using time triangulation. Data analysis uses reduction, exposure, and categorization concepts so that students' visual thinking schemes can be obtained in understanding the concept of solving trigonometric equations.
