Pengembangan Sistem Penyortir Bawang Otomatis Menggunakan Sensor Ultrasonik Sebagai Media Pembelajaran Pada Mata Kuliah Sistem Kontrol Otomatis

Abstract

This research aims to create a learning media for an automatic onion sorting system using ultrasonic sensors based on the size of the onions. It also aims to assess the feasibility of the system and gauge the response of students towards the learning media for the automatic onion sorting system using ultrasonic sensors in the course of Automatic Control Systems at Undiksha (University of Pendidikan Ganesha). The research employs the Research and Development (R&D) methodology. Data collection for this research was conducted through questionnaires, which were assessed by content experts, media experts, and active students of the electrical engineering education program at Undiksha. The results of the research are as follows: the validation test by content experts achieved a percentage of 97.7%, indicating a qualification of "very feasible." The validation test by media experts obtained a percentage of 95%, also classified as "very feasible." The small group test with 5 respondents resulted in a qualification of "excellent" for all respondents. Additionally, the large group test with 15 respondents also yielded a qualification of "excellent" for all respondents. Based on the research findings, the development of the automatic onion sorting system using ultrasonic sensors as a learning media for the Automatic Control Systems course at Undiksha is considered suitable and can be utilized effectively in the process of teaching automatic control systems.
