Renewable energy props development

摘要

Against the background of the findings in the field that renewable energy props are still very limited in availability and use. In line with this, the purpose of this study is to develop renewable energy teaching aids for high school students. The research methodology used is research development and literature review. The development model used in this study is Borg and Gall. The instrument used in this study was a questionnaire. Validation is carried out by material and media experts. The validity results are calculated using the Product Moment formula, while the reliability is calculated by the KR-20 formula. Props that have been successfully developed in the form of miniature houses with solar-based electricity and mechanical energy on the roof. This trainer is equipped with a charge to store electrical energy, lights, fans and bells as an output indicator. Make it easy for students to change the angle of light coming or falling objects making it easier for students to take data to compare the electrical energy produced at different angles and heights of falling objects.
