Development of AC to DC Current Converter Demonstration Tools in the Electrical Circuits Course

Abstrak

Instruction in the Electric Circuits course requires media capable of making abstract concepts more concrete, particularly regarding the conversion of AC to DC current. This study aims to develop and test the feasibility of an AC-to-DC conversion demonstration tool as a learning aid. The research employs the Research and Development (R&D) methodology, specifically the 4D model, which consists of four stages: define, design, develop, and disseminate. Data were collected through validation by two subject matter experts and two media experts, as well as via a response questionnaire administered to 12 students during a limited-scale trial. The results indicate that the developed demonstration tool is highly feasible, with validation scores of 88% from subject matter experts and 91% from media experts. Student feedback yielded an 80% approval rating, categorized as "good." These findings demonstrate that the tool effectively helps students grasp the AC-to-DC conversion process in a more concrete manner and supports independent learning, making it a suitable supplementary learning resource for the Electric Circuits course.
