Abstract

The integration of science learning through experimental activities is crucial in enhancing students' understanding of natural product chemistry. This study explores the antioxidant potential of Centella asiatica (Gotu kola) extract as a contextual learning medium in scientific education. Centella asiatica is a medicinal plant widely used in traditional medicine for its bioactive compounds, including triterpenoids, flavonoids, alkaloids, and saponins, which exhibit significant antioxidant properties. This study aims to evaluate and compare the antioxidant activity of C. asiatica extracts obtained using three different solvents: 70% ethanol, N-hexane, and ethyl acetate, utilizing the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Antioxidant activity was assessed based on the ability of the extract to scavenge DPPH radicals, measured spectrophotometrically at a wavelength of 517 nm. The findings revealed that all extracts exhibited antioxidant activity, with the 70% ethanol extract demonstrating the highest potency, achieving an IC50 value of 19.50 µg/ml, compared to N-hexane and ethyl acetate extracts. These results highlight the potential of C. asiatica as a natural antioxidant source, relevant for health product development and scientific experimentation in educational settings. This study underscores the importance of incorporating laboratory-based research into science curricula to enhance students' analytical and experimental skills while fostering an appreciation for the application of natural product research in health sciences.

Abstract

Teacher Professional Education (PPG) students as prospective educators have an important role in instilling national values in students. However, their understanding of the concept of defending the country still needs to be improved. Therefore, this service activity aims to provide education about defending the country to PPG students of Cenderawasih University in order to build their nationalism and patriotism character. The subjects in this activity are all students of the Cenderawasih University Pre-Service PPG Program. The scheme of community service is by going directly to the students to socialize and provide understanding to PPG students regarding National Defense which is the theme of this community service. There was a significant increase in student understanding after participating in this educational activity. Before being given the material, only 40% of students obtained a score above 70 in the pre-test, while after education, as many as 85% of students achieved this score in the post-test. This increase shows that the methods applied in this activity are effective in increasing students' understanding of defending the country. The national defense education provided to PPG students of Cenderawasih University has been proven to be able to increase their understanding of the importance of nationalism and patriotism. For the next service, it is recommended to have a more interactive approach and a wider range of participants so that the impact is more optimal
