SISTEM MONITORING PLTS BERBASIS IOT SEBAGAI MEDIA PEMBELAJARAN

Abstrak: Penelitian ini bertujuan untuk mengembangkan sistem monitoring pembangkit listrik tenaga surya (PLTS) berbasis Internet of Things (IoT) sebagai media pembelajaran di Jurusan Pendidikan Teknik Elektro Universitas Negeri Medan. Sistem monitoring ini dinamakan EduSolar, yang dirancang menggunakan kombinasi perangkat keras seperti mikrokontroler Arduino UNO, modul sensor arus, tegangan, daya, intensitas cahaya, serta modul WiFi ESP8266 untuk konektivitas IoT. Sistem EduSolar dapat memantau dan menampilkan parameter-parameter penting PLTS secara real-time melalui antarmuka website. Penelitian ini menggunakan metode pengembangan ADDIE yang terdiri dari tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Hasil validasi ahli media menunjukkan persentase kelayakan 81,28%, sedangkan validasi ahli materi mencapai 80,83%. Uji respon mahasiswa juga menunjukkan bahwa sistem EduSolar dinyatakan "layak" digunakan sebagai media pembelajaran dengan persentase 78,46%. Dengan demikian, sistem monitoring PLTS berbasis IoT yang terintegrasi sebagai media pembelajaran ini terbukti efektif dalam meningkatkan pemahaman mahasiswa tentang teknologi energi surya. Kata Kunci: Sistem Monitoring PLTS, IoT, Media Pembelajaran, Pembelajaran Interaktif, Energi Surya.  Abstract: This research aims to develop an Internet of Things (IoT)-based solar power plant (PLTS) monitoring system as a learning media in the Department of Electrical Engineering Education at Medan State University. The monitoring system is called EduSolar, designed using a combination of hardware devices such as the Arduino UNO microcontroller, current, voltage, power, and light intensity sensor modules, as well as the ESP8266 WiFi module for IoT connectivity. The EduSolar system can monitor and display real-time important parameters of the solar power plant through a website interface. This research utilizes the ADDIE development method, which consists of analysis, design, development, implementation, and evaluation stages. The validation results from media experts showed a feasibility percentage of 81.28%, while the validation by subject matter experts reached 80.83%. The student response test also indicated that the EduSolar system was deemed "feasible" as a learning media with a percentage of 78.46%. Therefore, this IoT-based PLTS monitoring system integrated as a learning media has been proven effective in enhancing students' understanding of solar energy technology. Keywords: PLTS Monitoring System, IoT, Learning Media, Interactive Learning, Solar Energy.
