<![CDATA[The limited interactive learning media regarding renewable energy in vocational schools has an impact on the low creativity and learning motivation of students. This study aims to develop a feasible, practical, and effective Arduino-based Solar Tracker Training Kit. Using the ADDIE model Research and Development (R&D) method, this research was conducted at SMKN 3 Jombang with 36 subjects of grade XI Industrial Electronics Engineering through a one-group pre-test post-test design. Data were collected through observation, interviews, questionnaires, and tests using validation sheet instruments, response surveys, and evaluation questions. Data analysis applied descriptive statistics percentages, N-Gain tests, and Wilcoxon tests because the data were not normally distributed (< 0.05). The results showed that the product was "Very Feasible" according to material experts (89.28%) and media experts (91.66%), and "Very Practical" based on student responses (82.36%). This tool was proven to be effective in increasing creativity (N-Gain 0.79) and learning motivation (N-Gain 0.82) in the high category. The Wilcoxon test confirmed the findings with a significant difference between pre-test and post-test scores (Asymp. Sig. < 0.05). It was concluded that this media is feasible and effective for implementation in vocational schools. Future development is recommended to integrate an IoT-based monitoring system and develop specific teaching modules. ]]>
