Abstract

This study aims to determine the response of students to the use of comic media in science learning with static electricity material which the authors expect to get a positive response from students and can help reduce student boredom in science learning using comic media. By making media that is fun and does not make students bored, students will be more enthusiastic in learning and the learning process can take place well without any complaints from students who feel bored by only using written media. Material static electricity is one of the branches of physics material that is important for students to understand. By using comic book media in delivering static electricity with a few pictures, it can reduce student boredom and it will be more fun than just writing. This research method uses a qualitative method by surveying the opinions of several students in different schools regarding the use of comic media on online system static electricity material using the whats app group. The results of the study showed that many students were interested in the use of comic media compared to only using writing in science learning with static electricity in online systems.                        Keywords: student responses, comic media, science learning, static electricity, online

Abstract

For instance, the scalar control is a variable regulation of volt per hertz to sets the magnitude scaling of the motor, of course by linearization of two parameters that is voltage and frequency, which sets to a constant ratio for the only concept of scalar control. In contrast, this method has the disadvantages that cannot decrease or increase the speed range from lower voltage of low speed or upper limit voltage of high speed, due to a certain regions are experiencing issues in constant ratio precision because of switch loss. The resulting output signal is not only has a high harmonic which would lead to losses in the form of heat, but is also causes poor performance at low frequency. For investigation, we used simulation using Direct Torque Control or also called DTC. The application of DTC, becoming one of the motor drive method of induction motor, and would produce the efficient power consumption because of switching pattern based on vector voltage. For simulation result, we use the test techniques when unencumbered and when burdened by parameters of rise time value, settling time value, and set point value.
