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

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.

Abstract

Sanitation remains a persistent challenge in elementary schools in Jayapura Regency, particularly in Waibu and Sentani Districts. Limited facilities combined with low awareness among teachers and students have negatively affected both health and learning quality. This community engagement program sought to strengthen elementary school teachers’ capacity to design Artificial Intelligence (AI)-based sanitation teaching materials through a Continuous Professional Development (CPD) framework. Thirty teachers from twelve partner schools participated in training, mentoring, and evaluation sessions. The initiative produced 20 draft teaching modules, of which 12 schools successfully applied them in classroom settings. Teachers’ competencies showed a marked improvement, as reflected in the increase of average scores from 76 (pre-test) to 89 (post-test). Classroom observations also demonstrated greater student engagement in sanitation practices, such as proper handwashing and waste disposal. These findings highlight that AI-based teaching materials are both feasible and effective for promoting contextual sanitation education in resource-constrained schools. Nevertheless, persistent challenges related to limited devices, unstable internet connectivity, and inadequate sanitation infrastructure underscore the need for extended mentoring and stronger support from local authorities.

Abstract

Pembelajaran biologi tentang materi spermatophyta di sma masih terasa umum dan kurang mengaitkan potensi lingkungan sekitar sebagai sumber belajar yang relevan dengan konteks kehidupan siswa. Penelitian ini bertujuan mengembangkan modul pembelajaran biologi tentang spermatophyta yang menggunakan potensi lokal di laboratorium pertanian terpadu jagan, sukoharjo, untuk siswa SMA kelas X fase E sesuai kurikulum merdeka. Penelitian ini menggunakan metode research and development (r&d) dengan model borg dan gall yang dimodifikasi menjadi tujuh tahap. Potensi lokal diperoleh melalui observasi di lapangan dan identifikasi tumbuhan spermatophyta, terdapat total 54 spesies yang terdiri dari gymnospermae dan angiospermae (monokotil dan dikotil). Kelayakan modul dinilai oleh ahli materi, ahli modul, guru biologi, dan siswa kelas X menggunakan instrumen penilaian. Hasil validasi menunjukkan persentase kelayakan sebesr 86,58%, dari ahli materi dan ahli modul, 87,89% dari guru biologi, serta 91,59% dari siswa yang termasuk dalam kategori sangat layak. Dengan demikian, modul Spermatophyta berbasis potensi lokal layak dijadikan bahan ajar tambahan dalam pembelajaran biologi di SMA. Modul ini mendukung pembelajaran kontekstual dan pemanfaatan potensi lokal sebagai sumber belajar, sekaligus meningkatkan keterampilan proses sains, berpikir kritis, dan kepedulian siswa terhadap lingkungan.
