Semarang – A community service team from the Physics Study Program, Faculty of Science and Mathematics, Diponegoro University, carried out an environmental education program at SMA Islam Al-Azhar 14 in Semarang City. The activity aimed to enhance students’ knowledge, skills, and awareness of air pollution, while introducing a simple technology in the form of an air filter made from golden pothos (Epipremnum aureum) and activated carbon.

Many students took part in this Project-Based Learning program. The activity series included a pre-test, interactive material delivery, ice-breaking sessions, a hands-on air filter construction demonstration, and a post-test. Evaluation results showed an increase in the average score from 68.88 to 89.05, reflecting a significant improvement in students’ understanding of air pollution and its mitigation strategies.

Team leader Muhammad Syahdan Yudha explained that golden pothos and activated carbon were chosen for their high effectiveness in absorbing air pollutants. Golden pothos possesses strong phytoremediation capabilities, while activated carbon can adsorb harmful particles and gases without requiring additional energy. “This combination provides a dual solution—biological and physical—that is affordable, easy to implement, and suitable for school environments,” he said.

Field observations revealed strong enthusiasm among the students, particularly during the practical session. They actively asked questions, engaged in discussions, and even suggested creative modifications to make the filter design more attractive and user-friendly. This program not only enriched students’ knowledge but also equipped them with practical skills applicable in daily life.

According to supervising lecturer Oki Ade Putra, this initiative aligns with UNDIP’s mission to support the Sustainable Development Goals (SDGs), particularly in the areas of air quality and sustainable environmental education. In the future, similar programs are expected to be replicated in other schools as part of a national movement to create healthy and environmentally friendly learning environments.
