Tilatang Kamang Village, which is in the rural area, causes most students to have limited access to technological developments, especially in terms of practical equipment in the laboratory. This limitation causes students to be unable to think quickly, and has an impact on the speed and accuracy of students in practicing in the laboratory. Existing teaching aids are ineffective, because they only consist of circuit boards that require a long time and make it difficult for students to operate. Low ability and limited experience of students at SMKN 1 Tilatang in using laboratory equipment are also the causes of ineffective learning, especially in the learning of electrical and electronic circuits. This type of research is Research and Development which uses the Borg and Gall research procedure. The research subject is the electric circuit media trainer and the respondent was a teacher of Basic Electricity and Electronics and an electrical student at SMKN 1 Tilatang Kamang. The research instrument is the trainer questionnaire validation, practicality, and effectiveness of the trainer. Data analysis includes trainer validity, practicality, and trainer effectiveness. The results showed that the trainer's validity was 90% with a valid category. The practicality of the trainer is viewed from the teacher's side by 96% with very practical criteria, while the average practice in terms of students is 90% with very practical criteria. The average effectiveness of trainers is 86.9% with effective criteria. © 2019 IOP Publishing Ltd. All rights reserved.
