PKM PENINGKATAN KOMPETENSI PLC TENAGA PENDIDIK TEKNIK INSTALASI TENAGA LISTRIK SMKN 6 TAKALAR
Get PDFElectrical Power Installation Engineering at SMKN 6 Takalar is the only major in Takalar that is an option for students who are interested in electrical lighting installation problems. Through the curriculum renewal, SMKN 6 Takalar not only focuses on electromechanical control (contactors and relays) but also PLC control. In 2023, SMKN 6 Takalar received assistance in the form of 5 PLC practical modules from the South Sulawesi Provincial Education Office, but this module could not be used, considering that the teacher in charge had difficulty using the practical module. This is because the 3 teachers in charge of the module do not yet have adequate knowledge in using PLCs and the modules provided are quite difficult to use for beginners. For this reason, this community service activity aims to provide solutions to existing problems by providing basic PLC training to teachers and students using assistance in the form of trainer modules and practical guides. The results of the community service in the form of a 60X40x15cm trainer module make it easier for teachers and students to program PLCs and wire input/output components.
