Development of an Analog Filter Trainer for Enhancing Practical Skills and Conceptual Understanding in Electrical Engineering Education

Students enrolled in the Electrical Engineering Education program encounter obstacles when attempting to access costly hardware and face the potential for damage during electronics circuit practicums. This research project aims to develop an analog filter trainer as an effective and efficient practicum tool, with the objective of enhancing students' understanding of fundamental concepts and practical skills in electrical engineering. The study employs the Research and Development (R&D) method using the ADDIE model, which comprises five stages: analysis, design, development, implementation, and evaluation. The developed learning media includes a low-pass filter (LPF), a high-pass filter (HPF), a band-pass filter (BPF), and a jobsheet to support practicums in electronics circuits. The analog filter trainer incorporates key components such as an audio frequency generator circuit, an audio filter circuit block, an LCD, and a rotary switch. Test results demonstrate that this trainer meets the specified criteria and received high validation from media experts (87.83%) and content experts (84.16%). Student responses were also very positive, with a rating of 85.67%. The use of the analog filter trainer as a practicum tool has been shown to enhance students' understanding of basic electronics circuit concepts and practical skills. This media also reduces costs and the risk of hardware damage.
