Abstract

Background: Learning media training is one of the important factors in improving learning outcomes, with learning media that suits the needs, especially students of SMK Teknologi Yayasan Pendidikan Sinar Husni can understand learning. The purpose of the implementation of the community partnership program (PKM) is to produce interactive learning media that is valid, practical and effective to help students of SMK Teknologi master the field of Electronics and Control. Method: The method for implementing Community Partnership Service activities for SMK Teknologi Yayasan Pendidikan Sinar Husni, Department of Electrical Engineering / Electricity, is by first making observations to the location of the School where the Community Service is held, as well as sharing with several Electrical Engineering teachers.  This is done to identify service methods that are in accordance with the conditions of the Community Partnership Service Team Partners in the field, so that later it will be right on target. Result: This activity can make and understand basic Arduino Uno learning media and implement it well. Conclusion: It is hoped that in the future this activity can inspire and motivate the participants and can innovate in the development of science and technology in the world of Electronics and Control Instrumentation to support the Industrial Revolution 4.0 program.

Abstract

The alternator is a crucial component in electrical systems that functions to convert mechanical energy into electrical energy. The torque applied to the alternator shaft significantly affects its performance. This study investigates the impact of torque variations on the performance of an inverter that receives power supply from the alternator. An experimental method was employed to test the alternator-inverter system under varying loads. The measured data includes voltage and current at the inverter output, as well as different torque levels used to drive the inverter. The results indicate that low torque produces unstable DC voltage. In the tests, the alternator drive operated at a speed of 1057 RPM, an angular velocity of 110.5 rad/s, and a torque of 9.049 Nm, resulting in the inverter being unable to provide ideal AC output. Conversely, higher and stable torque allows the inverter to generate AC voltage with a constant frequency close to its nominal value. These findings emphasize that the alternator's torque directly influences the stability and efficiency of the inverter. The main conclusion of this research is that the quality of power produced by the inverter is significantly affected by the stability of the alternator's torque, with the alternator output power being 1000 Watts and an efficiency of 90% or 0.9. Therefore, torque control is a critical component in the design of power supply systems reliant on alternators.
