Abstract

This study explores the use of graphene-based nanofluids in enhancing the performance of solar-powered desalination systems. A laboratory-scale desalination system was developed to simulate the evaporation process, powered by solar energy, with the integration of graphene-based nanofluids to improve thermal efficiency. The experimental setup measured evaporation rates, energy consumption, and temperature profiles under varying solar radiation conditions (400–800 W/m²). Results revealed that the system with nanofluids demonstrated up to a 35% increase in evaporation rates compared to the baseline system without nanofluids, indicating enhanced heat transfer properties. Moreover, energy consumption was reduced by up to 20%, highlighting the improved energy efficiency of the system with nanofluids. The system with nanofluids exhibited higher temperatures in the evaporator, confirming more effective thermal utilization. Statistical analyses, including t-tests and regression analysis, confirmed the significant impact of nanofluids on both evaporation rates and energy consumption. This study demonstrates that graphene-based nanofluids offer a sustainable and energy-efficient solution for solar-powered desalination, particularly in areas with abundant solar radiation. The integration of nanofluids not only enhances the efficiency of the desalination process but also reduces operational costs, making it a promising alternative for addressing water scarcity in a sustainable manner. Further research is needed to optimize nanofluid formulations and assess their long-term feasibility for large-scale applications.

Abstract

Bullying cases among elementary school students have become increasingly alarming because they negatively impact children’s psychological, social, and moral development, making early intervention essential. This community service project was designed to strengthen students’ understanding and character formation as a preventive effort against bullying behavior. The program was carried out at SD Wonolelo, a rural elementary school, involving 18 sixth-grade students and one accompanying teacher who participated actively in each session. The methods used consisted of interactive socialization and role-playing activities implemented through three stages: delivery of material, interactive question-and-answer discussion, and final evaluation. The results show a significant increase in students’ comprehension of bullying, rising from 30% before the activity to 90% afterward, indicating the program’s strong impact on learning. Beyond improved understanding, the initiative successfully cultivated empathy, cooperation, and social awareness among students so that they not only refrain from bullying but also feel responsible for preventing it within their environment. Overall, the program proved effective in promoting anti-bullying awareness, shaping positive character traits, and supporting the development of a safer and more inclusive culture at the elementary school level.
