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

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

Cauliflower (Brassica oleracea var. botrytis L.) during its development period needs to be controlled by pests and diseases, because at that time the flowers or krobs come out and will determine the quality and quantity of its production. This research is conducted to characterize and differentiate various types of pests and diseases found in cauliflower plants in the gardens of Gonaman Village, Koripan, Matesih District, Karanganyar. This research employs a methodology based on descriptive qualitative analysis. The tools utilized in this study include a mobile phone, writing instruments, and observation sheets. The research subjects consist of various pests and diseases identified in the garden area. Data collection by observation of the garden and direct interviews with garden owners. For data analysis and validation, qualitative descriptive techniques are used with additional interview activities with cauliflower farmers and literature studies. Based on the results of the study, eight pests have been found, namely; Whitefly / Cabuk (Aphis brassicae), Thrips (Thrips tabasi), Whitefly (Aleyrodidae sp), Crop Caterpillar (Crocidolomia binotalis), Ladybug (Illeis galbula), Brown grasshopper (Valanga nigricornis), Leaf beetle (Aluacphora sp), Leaf caterpillar (Plutella xylostella). And four diseases were found; Alternaria brassicae fungus, bacterial rot by Pectobacterium carotovorum, Erwinnia carotovora bacteria, and Xanthomonas camprestis bacteria. The visible symptoms are damage to the leaves, yellow, brownish to blackish leaves, rotten and wilted flowers so that they can reduce the harvest. Pest and disease control can be done by spraying pesticides, fungicides once a week, maintaining land cleanliness, maintaining planting distance, selecting healthy seeds, and providing lime and boren. For further research, it should be done for several days, in the morning and evening when insects are active.

Abstract

This study explores the social interaction behaviors of domestic pigeons (Columba livia domestica) during the matchmaking period. The aim is to understand how multi-channel communication through body movements, vocalizations, and tactile contact affects the formation of pair bonds. This research employed an observational method at the Green House of Universitas Veteran Bangun Nusantara using the ad libitum sampling technique to record daily behaviors of pigeons kept in a confined space. The results revealed that male pigeons predominantly initiate interactions, while females exhibit selective responses that determine mating success. Characteristic behaviors such as bowing, cooing, billing, and allopreening were observed to follow a sequential pattern from orientation and approach to attraction and acceptance. These findings suggest that the intensity and consistency of social interactions significantly contribute to successful pair bonding in domestic pigeons. Future research may investigate hormonal or neurological aspects that underlie these social behaviors.
