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

Abstract

Background: Bacteria in nature can have various effects on human life, including the development of diseases. Consequently, it is necessary to regulate or inhibit the growth of harmful bacteria. One method of doing so is through the use of natural ingredients, such as Matoa (Pometia pinnata). This study aims to provide a literature review on the potential of various Matoa plant extracts as antibacterials. Methodology: The investigation was conducted using the PRISMA approach, which involved the systematic literature review method. Electronic databases, including PubMed, ScienceDirect, Scopus, and Google Scholar, were searched from 2010 to 2024. "Pometia pinnata" is a search term that encompasses " Pometia pinnata as antibacterial" and "Antibacterial Activity of Pometia pinnata." A qualitative analysis was conducted on 22 articles that satisfied the inclusion criteria following the selection process. Findings: The review results indicated that the extracts of matoa's leaves, seeds, and bark contain active compounds, including flavonoids, tannins, saponins, alkaloids, and other phenolic compounds, which exhibit antibacterial activity. Despite the large potential, the majority of the research is still exploratory and has not yet progressed to the clinical trial stage. Consequently, additional, more intensive research is required to investigate the mechanism of action, toxicity, and potential clinical applications of herbal medicines derived from indigenous Indonesian plants. Contribution: This review highlights the antibacterial potential of matoa (Pometia pinnata) and underscores the need for further studies on its mechanism, toxicity, and clinical application, thereby guiding future research on Indonesian herbal medicine

Abstract

The Potential of Papua's Gogauke for Bio-Excellent Superior Products Papua possesses abundant biodiversity, and the Provincial Government is committed to green growth and sustainable natural resource management. Based on Special Autonomy, the rights of indigenous communities to protect the forests are also recognized. Local plants are often overlooked, despite having great potential. One such plant is Gogauke (Centella asiatica), traditionally used by Papuans as medicine. This plant is known to have various benefits, such as anti-inflammatory properties, wound healing, and pain relief. The objective of this research is to determine the potential of gogauke as a natural raw material for the superior product "Bio-Excellent" through phytochemical screening of the bio-oil produced. Using an experimental method, the study shows that Gogauke bio-oil has very strong potential for development. Phytochemical tests prove the product is rich in secondary metabolite compounds, including Alkaloids, Flavonoids, Triterpenoids, Tannins, Phenols, Steroids, and Glycosides. This combination of compounds provides a scientific basis for broad biological activities (antioxidant, anti-inflammatory, and antifungal). Furthermore, physical parameters (water content 9.8%, yield 44.14%) and microbiological test results (TBC and YMK) indicate that the bio-oil is safe and stable, meeting the BPOM standards for natural medicinal products. Conclusion: Gogauke bio-oil has a superior biochemical profile and high market potential, making it a promising "Bio-Excellent" product derived from Papua's sustainably managed natural resources.
