Abstract
This research aimed to produce a device for converting heat energy into electrical energy as a teaching aid for physics. This research process is development research, which refers to the Research and Development (R&D) model. The instrument used was a questionnaire with a five Likert scale, which addressed media experts, material experts, physics teachers in SMA Negeri 2 Sigi, and class XII MIA SMA Negeri 2 Sigi students. The product quality data obtained were analyzed using descriptive analysis. Based on the analysis of the media expert’s assessment, the quality of the product obtained a percentage value of 87.69% with the interpretation of “Very Good”. Based on the analysis of the assessment by material experts, the quality of the product obtained a percentage value of 84.44% with the interpretation “Very Good”. For the results of the physics teacher’s response, a percentage value of 86.00% was obtained with the interpretation “Strongly Agree”. For the results of the responses of class XII MIA students in the limited test, a percentage value of 83.56% was obtained with the interpretation “Strongly Agree”. The test results and questionnaire analysis showed that the heat energy conversion device developed into electrical energy was feasible to use.
