INTRODUCTION
At this time the community was faced by the era of industrial revolution 4.0 which led to massive changes in various fields. The impact of the industrial revolution 4.0 era on education, today is not only focuses on how teachers teach and how students respond to learning, but now education must prepare students to be able to deal with three things,: 1) preparing students to be able to work at work which is not available now; 2) preparing students to solve the problem, which does not yet exist at this time; and 3) preparing children to be able to use technology. Based on these three things students are required to have the ability to think critically, creatively, innovatively, communicatively, collaboratively, and confidently.
Creative and critical ways of thinking are the two main things needed in preparing for the era of industrial revolution 4.0, because they have a positive impact on themselves and a positive impact on their environment. Permendikbud No. 81A of 2013 concerning curriculum implementation states that students' future competency are needed, such as communication, creative, and critical abilities. One effort in improving creative thinking skills and critical thinking skills is by renewing learning media that synchronizes the times and in accordance with the technology being applied.
Learning media is a thing that cannot be separated from teaching and learning activities, this is because learning media can influence or benefit teachers and students. For students the use of learning media can provide a stimulus to focus, be independent, skillful and real experience. For teachers learning media is used to ease delivering learning material.
The selection of learning media to synchronize the objectives of the learning goal. Heinich (1996) states that the selection of learning media uses the USSURE principle

ARTICLE HISTORY
which includes Analyze Learners, State Objectives, Select methods, media, and material, Utilize media and materials, Require learner participation, Evaluate and revise.
In engineering study, the use of learning media is different from learning in other fields, this is because learning in the field of engineering is more focus on the type of not projected learning media, that is real work media, where learning media have a collaborative system with actual tools. Learning media is hardly influence the creativity and critical thinking skills of students, so that in the end it will affect the learning outcomes and student success in the future. The relationship of creativity and critical thinking towards learning outcomes has a very close relationship. Ali and Ansori (2004: 41) state that the development of creativity has a very close relationship with individual cognitive development, since creativity is the embodiment of the work of the brain.
In the field of engineering, especially in since department of electrical engineering study program, there are many learning media used, for example in practicum study, learning media used are lighting installation media trainers and industrial panels. Based on the results of observations and interviews on students, the learning media used in electrical engineering study programs are patent learning media, in which students must do practicum in the same place and cannot move. One of them is that learning media used in practicum subject are industrial electrical panel media.
The advantages of this learning media are the shape, layout, and working system exactly the same as industry panels in the industry, but the weakness of this learning media is that students must practice in the same place because this learning media is patent, besides this learning media not yet equipped with components that have not been installed, so that when students do practicum and make a series of electric motor controller, students will need a long time to install the components first, then create a series of control systems. This learning media is quite good for teaching and learning process, but this learning media is still lacking in increasing student creativity and critical thinking, this can be seen from the results of observations, where students tend to be less active, lack of ideas or solutions, and have difficulties in presenting the results of their work, students do not discuss the problems faced in doing group assignments.
Based on the background, this study provides portable trainer electric motor as learning media which is efficient to: 1) place efficiency, this media has a practical luggage bag to carry and used in everywhere; 2) efficiency in usage, this learning media is equipped with control system components that have been installed on the trainer so that students can easily install various series of control systems through jumper cables; 3) time efficiency, the time for running the circuit is relatively much faster than the industrial panel learning media that is used as a medium of learning today, because students only need to create a series of control systems without installing the components first; 4) efficiency in maintenance, because this learning media is made of acrelic and wood so that it is easy to clean and check if an error occurs.
The purpose of this study is to determine the affectability in the use of portable type electric motor control trainer media on increasing creative thinking skills and critical thinking skills in electrical engineering students.
