Abstract

The growing demand for functional foods has encouraged the development of dairy products enriched with natural bioactive ingredients to improve nutritional value and health benefits. This study aimed to analyze the nutritional composition and antioxidant activity of yogurt enriched with butterfly pea (Clitoria ternatea L.) extract. Yogurt was prepared from fresh goat milk with varying concentrations of butterfly pea extract and evaluated for protein, fat, carbohydrate, moisture, ash, vitamin C contents, antioxidant activity, and sensory acceptance. Proximate analysis, UV–Vis spectrophotometry, and the DPPH method were used for chemical determinations, while a hedonic test assessed color, taste, aroma, and texture. Results showed that increasing butterfly pea extract significantly decreased protein and fat contents but increased vitamin C and antioxidant activity, with the highest values observed in yogurt containing 60% extract and 4% formulation (N60K2). Moisture and ash contents were not significantly affected. Sensory evaluation indicated that yogurt with 60% extract and 2% formulation (N60K1) was preferred regarding color, taste, aroma, and texture. Considering compliance with the Indonesian National Standard (SNI) and consumer acceptance, N60K1 was the optimal formulation. The findings suggest that butterfly pea extract can enhance the functional properties of yogurt, particularly its antioxidant potential, while maintaining acceptable sensory quality. This provides insights for developing functional dairy products with natural plant-based bioactives.

Abstract

Red onion skin (Allium cepa L.) is often discarded as waste, despite being rich in flavonoids and alkaloids, which possess antioxidant, anti-inflammatory, antimicrobial, and anticancer properties. This study aims to determine the flavonoid and alkaloid content of red onion skin extract using reflux and Soxhlet extraction methods with 96% ethanol as the solvent. The extraction was performed using reflux and Soxhlet techniques, followed by UV-Vis spectrophotometry to quantify flavonoid and alkaloid content. A quercetin standard curve was used to determine flavonoid levels, while a caffeine standard curve was applied for alkaloid content analysis. The Soxhlet method yielded a higher flavonoid content (108.21 mg/g or 10.82%) compared to the reflux method (105.55 mg/g or 10.55%). In contrast, the reflux method resulted in a higher alkaloid content (169.56 mg/g or 16.95%) than Soxhlet extraction (167.0 mg/g or 16.70%). These differences are attributed to the continuous solvent circulation in Soxhlet extraction, which enhances flavonoid solubility, while the lower temperature in the reflux method prevents alkaloid degradation. The findings suggest that Soxhlet extraction is more effective for flavonoid extraction, whereas reflux extraction is better for alkaloid extraction. Given their significant bioactive properties, red onion skin extracts have potential applications in the pharmaceutical, nutraceutical, and food industries. Future research should focus on optimizing extraction techniques and conducting toxicological and pharmacological studies to explore the therapeutic potential of red onion skin extract.

The study uses explorative descriptive methods with qualitative and quantitative approaches. The focus of this study is the identification of feed source for endemic honeybees of Sulawesi, Apis nigrocincta through the analysis of polent morphology. Through the approach of polent morphology analysis, successfully identified 12 plant species from 9 families that could potentially be feed sources such as, Cucurbita maxima, Clematis viticella, Clematis montana, Pseuderanthemum tropurpureum, Cersicaria odorata, Solamun torvum, Solamun nigrum, Pine mercussii, Piper betle, Piper nigrum, and Galium aparine identification showed the presence of polyn diversity that supports the nutritional needs of bees, and emphasized the importance of local vegetation conservation to maintain the sustainability of the A. nigrocincta population. The results of the study showed that the polen has characteristics such as the polish unit, size, shape, shape on the P and E side, aperture type, as well as exin ornamentation. The polents collected by bees A. nigrocincta come from various types of plants, namely fruits, ornamental plants, vegetable plants, herb plants, and trees. This diversity reflects the flexibility of bees in choosing food sources based on availability in the surrounding environment. The results of the identification of the polymer samples showed that 12 species of plants that are the main feed source for A. nigrocincta bees are sourced from the polen. Each species has different flower characteristics, both in terms of shape and color. Polen diversity indicates that the environment around Jononunu Village has a rich ecosystem with different types of flowering plants.

Abstract

This study aims to determine the effect of Team Games Tournament (TGT) cooperative learning model assisted by Mysterious Card Box (KOKAMI) media on students' Biology Science learning activities and outcomes at SMP Negeri 19 Palu. Teacher-centered learning models tend to reduce student interaction and participation, so a more active and innovative approach is needed, such as TGT with KOKAMI media to improve student learning activities and outcomes. The research method used was quasi-experiment with post-test only control group design. Data were collected through activity observations and learning outcome tests, with samples taken purposively. Data analysis was carried out quantitatively through comparison of the average scores of experimental and control classes. The t-test results using SPSS ver.29 showed a significance value (2-tailed) of 0.001 < α 0.05. Thus, the alternative hypothesis (H1) which states that there is a significant difference in activity and learning outcomes between the experimental and control classes is accepted. This shows that the application of the TGT cooperative model assisted by KOKAMI media has a real effect in increasing the activity and learning outcomes of Biological Science. This model has the potential to be applied more widely to improve the quality of science learning at the secondary school level.
