Abstract
Programmable Logic Controller (PLC) is a competency that must be mastered by third-level vocational school students in an electrical motor installation course. PLCs can be operated using programming languages such as sequence function charts, block diagrams, instruction lists, ladder diagrams, and others. This competency is important because it is often used in the industrial world. To create better and more effective conditions in the teaching and learning process, the development of teaching aids is needed to improve and enhance students' skills. This research, to design and development a useful teaching and learning tool teaching medium to help teachers teach concepts PLC-based electrical control systems, both theoretically and practically. The ADDIE model was used in developing the aids. The verification stage is carried out to ensure that the teaching aids that have been developed are suitable for use. In addition, this kit is relatively small with dimensions of 45x34x20 mm and is easy to move and can be used in various places. Confirmation involves lecturers and teachers who teach the field of electrical engineering. The results of the study found that the respondents strongly agreed that the PLC teaching aids was suitable for use in the learning process. Respondents also stated that using the tool because did not waste time and was easy to use. However, it is suggested that further research be conducted to identify the effectiveness of this teaching aid on students.
