Abstract

This meta-analysis investigated how Maxwell's Equations and electromagnetic waves shaped key advances in modern technology. A systematic review was conducted across major academic databases, initially identifying 150 otential sources. Applying predefined inclusion criteria, findings were synthesized from 30 included studies. This synthesis revealed that these foundational concepts shaped technological advancement by providing the essential theoretical framework for understanding electromagnetic wave generation, propagation, and interaction with matter. This understanding was found to be pivotal in enabling breakthroughs across diverse domains identified in the synthesized literature, including Wireless Communication, Microwave Technology, Medical Imaging, Renewable Energy, and Metamaterials, among other related fields. This synthesis provides a comprehensive perspective on the mechanisms by which fundamental electromagnetic theory underpins technological progress. The findings underscore the enduring practical relevance of Maxwell's Equations and electromagnetic waves for research and engineering and offer valuable material for physics education by demonstrating their tangible impact in shaping the modern world.

Abstract

Science learning in junior high schools is still dominated by abstract and teacher-centered approaches, failing to realize the principles of pedagogical Deep Learning, which emphasizes mindful, meaningful, and joyful student understanding. This study aimed to develop an Internet of Things (IoT)-based Solar Power Plant (PLTS) experiment kit as a valid, practical, and effective Creative Problem Solving–STEM learning media. The study employed a 4D development model (Define, Design, Develop, Disseminate) with a one-group pretest-posttest design. The developed product consisted of solar panels, a Solar Charge Controller, a battery, and an inverter, integrated with an ESP32-based IoT module, relays, sensors, and the Telegram Bot platform. Validation was conducted by five experts using the Content Validity Index (CVI). The research subjects were 104 ninth-grade students at SMP Negeri 02 Semendawai Timur. The results showed that the IoT-based PLTS experiment kit was highly valid (CVI = 0.90) and very practical, with an average learning implementation of 84.75% and a positive student response of 89.03%. Furthermore, the kit was effective in improving students' Creative Problem Solving abilities, achieving an N-gain value of 0.53 (moderate category). This IoT-based PLTS experiment kit provides a learning experience that aligns with the demands of Industrial Revolution 4.0 and the principles of holistic educational Deep Learning.
