Abstract

Public health is increasingly becoming a major concern, especially in efforts to prevent disease through healthier and more natural consumption patterns. Herbal drinks have become one of the most widely developed alternatives because of their health benefits. Various medicinal plants have been traditionally used in folk medicine, including takokak leaves (Solanum torvum Swartz.), cinnamon (Cinnamomum spp.), and palm sugar (Arenga pinnata). Takokak leaves are known to contain bioactive compounds with potential antioxidant properties, while cinnamon and palm sugar contribute to enhancing palatability while enriching bioactive compounds. This study aims to formulate takokak leaf powder (Solanum torvum Swartz.) with cinnamon and palm sugar as a herbal beverage and evaluate its functional potential. This study is an experimental study with a completely randomized design (CRD) comprising six treatment combinations and one control. The results showed that the addition of cinnamon and palm sugar to the takokak leaf herbal beverage significantly affected the levels of flavonoids, phenols, tannins, and IC50. Flavonoid levels ranged from 6.38 to 9.71 mg/100g, phenolic content ranged from 4.67 to 6.49 mg/100g, tannin content ranged from 3.74 to 7.19 mg/100g, and IC50 values ranged from 19,293.34 to 42,290.50 ppm. The results also showed that all positive treatments contained alkaloid and saponin compounds. Based on the hedonic sensory test results, treatment P1 (2% cinnamon and 3% palm sugar) received the highest preference score compared to other treatments based on the parameters of color, aroma, taste, viscosity, and overall acceptance. These findings indicate the potential of takokak herbal beverage formulations as a source of natural antioxidants that are sensorially acceptable. Further research is recommended to evaluate takokak leaf herbal beverages with the addition of cinnamon and palm sugar in vitro and in vivo.

Abstract

Teaching reproductive education at the elementary school level remains a sensitive issue, balancing the need to prevent sexual abuse through proper knowledge with concerns about social, religious, and cultural norms. This study aims to explore the perceptions of prospective elementary school teachers in Gorontalo regarding reproductive content in science education. Using a descriptive quantitative design, data were collected from 60 respondents through a closed-ended questionnaire. The findings show that while most respondents opposed teaching reproductive material at the elementary level due to moral and cultural concerns, many were not against the content itself but rather the method of delivery and the consideration of children’s maturity. This suggests that reproductive education could be implemented if presented through contextual and values-based approaches, such as moral-educational narratives. The study highlights both the sensitivity of the topic and the potential pathways for its gradual and culturally aligned integration into science education.

Abstract

The demand for soybeans continues to increase, but local production remains insufficient, requiring strategies to enhance productivity and quality, such as the application of Plant Growth Regulators (PGRs). Natural PGRs derived from moringa leaves and mung bean sprouts, which are rich in auxins and cytokinins, have the potential to accelerate growth and stimulate the production of secondary metabolites. This study investigated various proportions of moringa leaf and mung bean sprout extracts to evaluate their phenolic content, antioxidant activity, and potential as natural PGRs in soybean cultivation. The extracts were analyzed using the Folin–Ciocalteu method for total phenolics and the DPPH assay for antioxidant activity. Among the treatments, Variation E, with a higher proportion of mung bean sprout extract, proved to be the most effective, enhancing both antioxidant activity and phenolic compound production. These findings highlight the novelty of combining moringa leaf and mung bean sprout extracts as a natural PGR strategy, demonstrating promising potential to support soybean growth and improve crop quality.

Abstract

Science learning is often regarded as difficult by students due to the many concepts that are abstract and not well understood. Therefore, a learning model is required that can enhance students' academic performance. One of them is the cooperative learning model known as Think-Pair-Share (TPS), which encourages students to think independently, engage in paired discussions, and share ideas within their groups. This research aims to determine the effect of the Think-Pair-Share type cooperative learning model on the learning outcomes of simple machines and efforts in SMP Negeri 1 Kwandang. This study is an experimental research, utilising a one-group pretest-posttest Design. The sampling technique employed in this research is Cluster Random Sampling. The sample in this study uses class VIIIC as the experimental class, grouped through a random lottery. Data for this research were collected using a testing technique, which included normality tests, hypothesis tests, and n-gain tests. The analysis results indicate that the calculated values for all sample classes are greater than the tabulated values; thus, the hypothesis (H1) is accepted. The N-gain value of 0.80 indicates an improvement in learning outcomes that falls under the high category. The application of the Think-Pair-Share model, specifically for the material on simple machines and business, has rarely been researched before. This model has been proven to help students connect abstract concepts with real-life situations, fostering active participation in the learning process. Thus, the TPS type cooperative learning model has a significant impact on improving students' learning outcomes. This research also provides practical benefits as a basis for teachers to implement the cooperative model of Think Pair Share in learning to create a more active, effective, and meaningful learning atmosphere.

Abstract

Chronic stress is known to cause neuronal damage in the hippocampus, particularly in the CA1 and CA3 areas, which play a crucial role in memory and learning. One way to prevent this damage is by using natural ingredients with neuroprotective properties. This study aimed to compare the effects of Centella asiatica and Mentha piperita leaf extracts, either singly or in combination, on the number of normal neurons in the hippocampus of male mice exposed to stress. Twenty-five male mice were divided into five treatment groups: K− (control without treatment), K+ (stress without extract), P1 (stress + Centella asiatica extract), P2 (stress + Mentha piperita extract), and P3 (stress + combination of Centella asiatica and Mentha piperita). Stress was induced using a restraint stress method, while the extracts were administered orally at the prescribed dosage. After the treatment period, the hippocampus was removed, and histological slides were prepared with Hematoxylin-Eosin staining to count the number of normal neurons in the CA1 and CA3 areas. The results showed that the K+ group experienced a significant decrease in the number of normal neurons compared to the K− group. Administration of gotu kola (P1) and mint (P2) extracts increased the number of neurons compared to K+, but not to the same extent as K−. The combination of Centella asiatica and Mentha piperita extracts (P3) showed the most optimal effect, with the number of normal neurons approaching that of the negative control group. These findings indicate that the combination of Centella asiatica and Mentha piperita has synergistic potential in protecting hippocampal neurons from stress-induced damage. Further research is needed to explore the molecular mechanisms underlying this neuroprotective effect.

Abstract

Biology learning in high school often faces challenges due to students’ reliance on teacher explanations and conventional textbooks, which tend to be less engaging and limit the development of critical and entrepreneurial skills. To address this issue, innovative teaching materials are needed that not only improve students’ understanding of biological concepts but also foster creativity and independence through entrepreneurship-based approaches. This study aims to develop and test the validity of biopreneurship-based biology teaching materials for high school students. The research employed a 4D development model (Define, Design, Develop, and Disseminate) with a focus on the first three stages. Validation of the teaching materials was conducted by three expert validators using questionnaires, and the results were analyzed with the Aiken index. The construct validity assessment produced values ranging from 0.58 to 0.94, while content validity ranged from 0.63 to 0.75, both categorized as valid. Additionally, the readability test using the Flesch-Kincaid Grade Level showed that most of the text fell within the easy-to-moderate range, making it suitable for high school students. These findings indicate that the developed materials meet the scientific and pedagogical standards required for classroom use. Furthermore, the integration of biopreneurship elements into the biology content provides an innovative approach that not only enhances students’ conceptual understanding but also motivates them to develop an entrepreneurial spirit, particularly in managing biological resources. Overall, this study concludes that the developed teaching materials are valid, relevant, and beneficial for high school biology learning, making biology both meaningful and applicable to students’ real-life contexts.

Abstract

Biological literacy and scientific attitudes are important aspects that need to be developed in students because they are related to the ability to understand biological concepts contextually and foster scientific thinking. This study aims to analyze the effect of the Problem-Based Learning (PBL) model on students' biological literacy and scientific attitudes. The type of research used is a quasi-experiment with a pretest-posttest control group design. The sample consisted of 58 eleventh-grade students at MAN Lombok Barat, selected using purposive sampling, with the experimental class receiving PBL instruction and the control class receiving conventional instruction. Data were collected through validated biology literacy tests and scientific attitude questionnaires. Data analysis techniques included mean value comparisons and ANCOVA tests using SPSS version 26. The results showed that the average biology literacy score in the experimental class increased from 53.8 to 72.5, while the control class increased from 53.5 to 76.6. In terms of scientific attitude, the experimental class improved from 32 to 36.9, while the control class increased from 36 to 37.2. The results of the ANCOVA test revealed a significant difference between the experimental and control classes in biological literacy, with a p-value of 0.004 (p < 0.05). Similarly, in the scientific attitude, a significant difference was observed with a p-value of 0.000 (p < 0.05). Based on these findings, it can be concluded that the application of PBL has a significant effect on improving students' scientific attitudes; however, its effect on biology literacy is less optimal than that of conventional learning. This is thought to be influenced by time constraints and other external factors that cannot be fully controlled during the research.

Abstract

Increased awareness of healthy lifestyles has spurred the growth of functional food trends among communities. Iron deficiency causes anemia, a major nutritional problem in Indonesia. Mangrove crab shells are a local source of iron. In most cases, the edible portion of crabs is limited to the meat, while the shells are discarded, leading to their high potential as a source of waste. The purpose of this study was to determine the effect of adding mangrove crab shell powder on the iron content of cookies. This study employed an experimental design using a Complete Randomized Design (CRD), with treatments of adding different concentrations of mangrove crab shell powder (0%, 3%, 6%, 9%, 12%, 15%). The data were analyzed using ANOVA and Duncan’s multiple range test. Findings indicated that adding mangrove crab shell powder significantly affected the iron content of the cookies. The iron content of the modified cookies ranged from 64.13 to 187.54 mg. The higher the concentration of crab shell flour added, the higher the iron content of the cookies. It is recommended that further research be conducted, encompassing organoleptic evaluation, microbiological contamination analysis, and heavy metal contamination assessment, to ensure the product's safety and quality. It is hoped that this research can serve as a reference on the use of crab shell waste as a source of iron that is beneficial to health.
