Abstract

Hydroponics is a planting technique using water-based nutrient solutions, not through soil media, like conventional farming. This hydroponic system solves the problems arising from soil-based farming that requires plowing and weeding and is susceptible to pests, climate, and the need for large land areas. However, to produce quality soil, the hydroponic system requires monitoring of nutrients, temperature, humidity, water content, pH, and light. Developing a smart hydroponic system or a system based on Artificial Intelligence of Things (IoT) can guarantee these parameters online or in real-time monitoring. The next problem is the need for a continuous and reliable supply of electrical energy so that the built AIoT-based hydroponic system can work optimally. Disruption of electrical continuity will affect the crop yields from this system. Therefore, the Community Service (PkM) activity from the Department of Electrical Engineering, Hasanuddin University, conducted socialization of the use of solar cells (solar panels) in the AIoT-based smart hydroponic system, which is a solution to the problem of the continuity of electricity supply at the Samata Green House (SGH) Group, as a partner of the activity, which still fully uses electricity from PLN. Based on the results of quantitative analysis of pre-test (before socialization) and post-test (after socialization) measurements by activity participants, an increase in the level of understanding of participants was obtained, which was initially 11-55% "quite understanding" to "understanding" of the components of the Solar Power Plant (PLTS) system, as well as how to operate and maintain PLTS, to 100% of participants "quite understanding" to "very understanding" regarding these parameters. This indicates that this activity has achieved the expected targets.

Abstract

The Community Service Program (PkM) conducted by the Department of Electrical Engineering aims to enhance the literacy and skills of students at SMKN 10 Makassar in understanding the concept of energy monitoring and the application of Internet of Things (IoT) technology as an innovative solution for energy management systems. The main problem identified in the school is the low awareness and understanding of energy efficiency, as well as the lack of monitoring tools capable of displaying real-time energy consumption data. Through socialization and training activities based on microcontroller technology, students were introduced to the working principles of current and voltage sensors, data transmission via the internet, and digital visualization of electrical energy consumption through IoT-based platforms. The activity evaluation was carried out using pre-test and post-test methods involving 25 students from the Electrical Engineering Department to measure comprehension improvement. The results showed a significant increase in two main aspects: understanding of the basic concepts of energy monitoring, which rose from 60% to 96%, and understanding of the integration of IoT in energy monitoring systems, which increased from 20% to 88%. These findings demonstrate that implementing IoT-based learning not only broadens students’ insights into energy efficiency but also strengthens their vocational competencies in electrical engineering through the application of intelligent technologies relevant to the needs of modern industry.
