Abstract

Education plays a critical role in shaping the cognitive, affective, and psychomotor development of students. In the 21st century, students are expected not only to acquire knowledge but also to develop the ability to think critically, solve problems, and apply concepts in real-life situations. For this reason, this study aims to determine the effect of applying the problem-based learning model assisted by mind mapping on student learning outcomes in ecosystem lesson. This research employed a quasi-experimental approach using the Pretest-Posttest Non-Equivalent Control Group Design, involving both control and experimental classes. The study population included all tenth-grade students at SMA Negeri 1 Biau. Through purposive sampling, four classes were selected, totaling 121 students. Learning outcomes data were collected using a test instrument comprising 30 multiple-choice questions. The data were analyzed using the Mann-Whitney statistical test at a significance level of 0.05. The analysis results revealed that the use of the problem-based learning model combined with mind mapping had a statistically significant impact on student learning outcomes, with a p-value less than 0.05 (0.000 < 0.05). Therefore, it can be concluded that the integration of mind mapping within the problem-based learning model has a positive influence on learning achievement. These findings suggest that this instructional approach is effective and can be implemented in lessons focused on ecosystem.

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

Honey is a valuable natural product with nutritional, medicinal, and economic importance, but its high commercial value makes it prone to adulteration, which threatens consumer trust and product quality. This study aimed to evaluate the effectiveness of simple purity tests in identifying adulteration in honey samples collected from several regions in Central Sulawesi Province. A total of 12 honey samples from different bee species and floral sources were analyzed using seven tests, namely solubility, cloudiness and foam, heating, hexagonal pattern, seepage, raw fish, and onion tests. The results showed that most tests successfully distinguished pure honey from adulterated samples. Specifically, the solubility, cloudiness and foam tests, as well as heating, and raw fish tests indicated that 66.67% of the samples were pure, while the hexagonal pattern, seepage, and onion tests confirmed purity in all samples (100%). These findings demonstrate that simple, low-cost methods can provide reliable initial screening of honey purity and are suitable for routine use in local communities where advanced laboratory facilities are limited. The application of these tests is expected to support honey quality assurance, protect consumer trust, and promote the sustainable development of the beekeeping industry in Central Sulawesi.

Abstract

Indonesia is recognized as one of the world’s biodiversity hotspots, supporting a wide range of pollinating insects, including honey bee species of the genus Apis. Among these, Apis cerana is the most widely managed species and contributes significantly to national honey production, particularly in Sulawesi. However, the increasing economic value of honey has led to frequent cases of entomological origin fraud, in which honey is falsely labeled as being produced by a different bee species. This study aimed to determine the entomological origin of honey sold in Central Sulawesi using the Major Royal Jelly Protein 2 (mrjp2) gene as a molecular marker. Seven honey samples claimed as “forest honey” were analyzed through DNA extraction, PCR amplification using species-specific primers (CF-CR), and sequencing followed by BLAST-n analysis. All samples yielded high-quality DNA with purity ratios appropriate for PCR amplification. PCR successfully amplified the mrjp2 gene, producing fragments of approximately 201-208 bp, consistent with the expected size for A. cerana. Sequence analysis showed percent identity values ranging from 99.20% to 100% when compared with reference sequences of A. cerana. Based on molecular verification, three samples (H3, H5, and H7) did not match the seller’s claims and were confirmed to originate from A. cerana rather than A. dorsata binghami. These findings demonstrate that sequencing of the mrjp2 gene is an effective and reliable approach to authenticate the entomological origin of honey and to detect fraudulent labeling in commercial honey products.
