Abstract

Access to safe and clean water remains a critical challenge in many educational institutions and local communities, particularly those relying on groundwater sources without adequate treatment. This community service program aimed to enhance students’ knowledge, technical skills, and environmental awareness through a workshop on constructing simple water filtration systems using locally available materials. The activity was conducted at SMK Darul Hikmah Kranjingan using a project-based learning approach that combined 20% theoretical instruction and 80% hands-on practice. Evaluation was carried out through pre- and post-activity surveys covering cognitive, psychomotor, and affective domains. The results indicate a substantial improvement in student competencies, where more than 60% of students reached moderate to very good levels of understanding in the cognitive domain, 70–80% demonstrated basic technical skills in assembling water filters, and over 90% showed positive attitudes toward clean water and sanitation. The constructed filter prototypes functioned effectively in improving water clarity based on visual observation. Overall, this program demonstrates that practice-based learning in community service activities is effective in strengthening vocational skills, improving water literacy, and fostering responsible water use behavior. The program contributes directly to the achievement of Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education), SDG 6 (Clean Water and Sanitation), and SDG 12 (Responsible Consumption and Production).

Abstract

Traditional fish smoking still causes environmental pollution and health issues due to uncontrolled smoke emissions. Field data indicate that 54.0% of workers in fish smoking centers are exposed to heavy smoke, and 66.7% experience severe respiratory symptoms, underscoring the need for cleaner technologies. This study developed an integrated solar-powered fish smoking system combining pyrolysis and a naturally cooled spiral condenser to convert combustion smoke into liquid smoke as a natural preservative. The prototype was designed and tested using corn cob biomass as the pyrolysis feedstock. Evaluated parameters included solar panel efficiency, smoking chamber performance, and liquid smoke quality. Characterization covered specific gravity, pH, acetic acid, phenol content, and heavy metals (Pb, Cd). Results showed that pure corn cob liquid smoke had a specific gravity of 0.99965 g/cm³, pH 3.55, acetic acid 1.747%, and phenol 7.8859%, while smoke applied to fish yielded 1.008572 g/cm³, 3.70, 3.950%, and 12.4242%, respectively. Both Pb and Cd were not detected (< LOD), confirming safety from contamination. Although acetic acid and phenol contents correspond to SNI 8985:2021 grade 2, further purification is needed to meet food-grade standards. The system effectively produces functional, antimicrobial liquid smoke while reducing emissions, supporting sustainable fish smoking and the circular economy.
