The Effect of the SrVER Learning Model Assisted by Augmented Reality Media on Biology Learning Outcomes
Get PDFEffective biology learning requires various components to enhance learning, including implementing appropriate learning models and media. This study examines the effect of the SrVER learning model assisted by augmented reality (AR) media on the biology learning outcomes of 10th-grade students at SMAN 2 Mataram. This research employs a quantitative approach using a quasi-experimental method with a non-equivalent control group design. The study population consists of 13 10th-grade classes at SMAN 2 Mataram, from which four classes were selected as the research sample using purposive sampling. Data was collected through questionnaires and student learning outcome tests. The data analysis techniques used in this study include the N-Gain statistical test and the Mann-Whitney test. The results show that the experimental class achieved an N-Gain score of 0.4 (moderate), while the control class obtained an N-Gain score of 0.2 (low). Furthermore, the Mann-Whitney test yielded an Asymp. Sig (2-tailed) value of 0.001, which is less than 0.05, indicating a significant difference between the post-test scores of the control and experimental classes. These findings confirm that implementing the SrVER learning model assisted by augmented reality media can significantly improve the biology learning outcomes of 10th-grade students
Plant-Based Probiotic Beverages in Preventing the Growth of Foodborne Pathogenic Bacteria: A Review
Get PDFFoodborne illnesses are mostly caused by bacteria. Bacteria, including Escherichia coli, Salmonella sp., Shigella sp. and Staphylococcus aureus, are the most common causes of foodborne diseases. One alternative to reduce the risk of infection from bacteria that cause foodborne diseases is the consumption of probiotic beverages, which has become a natural alternative in improving digestive health and endurance. One type of probiotic drink that is gaining increasing attention is plant-based kombucha tea. Plant parts that can be used as kombucha tea are fruits, leaves, and flowers and have antibacterial activity with various categories of inhibition zone strength. This research uses a systematic review and collects relevant articles, with 14 articles as the main reference. The analysis found that salak Bali fruit, pineapple honey fruit, belimbing wuluh fruit, tea leaves, soursop leaves, telang flowers, gardenia flowers, and red seaweed have the potential as a probiotic kombucha tea drink that can inhibit the growth of pathogenic bacteria that cause foodborne diseases. The categories of inhibition zones produced ranged from weak to very strong, with inhibition zone diameters ranging from 4.20 mm to 24.7 mm. The optimal zone of inhibition of this probiotic drink is influenced by the plant parts used, the length of fermentation, the type of substrate, the test method and the type of bacteria. Plant-based probiotic beverages show effective antibacterial activity against foodborne pathogens and offer valuable insights into microbial interactions and sustainable food biotechnology in scientific learning
The Effect of Problem-Based Learning Model on Students Scientific Reasoning and Scientific Attitude Abilities
No full textScientific Reasoning and Scientific Attitude are important aspects of scientific literacy for students to master because they are directly related to the development of science and technology. This study aims to analyze the effect of the Problem-Based Learning model on students' Scientific Reasoning and Scientific Attitude abilities. This type of research is classified as a quasi-experiment with a non-equivalent control group design. The study population consisted of 13 classes of the 10th grade of MAN 2 Mataram, from which two classes were selected as samples determined by purposive sampling techniques. Data were obtained by administering the Scientific Reasoning test and the Scientific Attitude questionnaire. Data analysis techniques include a comparison of average scores and the Mann-Whitney statistical test. The results showed that the experimental class obtained an average score of 75 points (formal), and the control class obtained a score of 72 points (transitional) on the Scientific Reasoning aspect. On the Scientific Attitude aspect, the experimental class obtained a score of 69 (High) and the control class obtained a score of 63 (Moderate). In addition, the Asympt. sig (2-tailed) value on the Scientific Reasoning aspect is greater than 0.05, which is 0.466, while on the Scientific Attitude aspect it is 0.003 or less than 0.05. Based on these findings, it can be concluded that although the Problem-Based Learning model has a significant effect on Students' Scientific Attitude Ability, its impact on Scientific Reasoning Ability is not statistically significant in the context of this study. This can be influenced by external factors that cannot be fully controlled in the research implementation process
Long Periodism on the Speed of Nine O’clock Flowers (Portulaca grandiflora)
Get PDFLong photoperiods can delay flower initiation and slow down the growth and formation of flower primordia, which can postpone flowering. This study aims to determine the photoperiodic response of the Nine O'clock flower (Portulaca grandiflora) to short light exposure. The research was conducted over one month (November-December 2024), with data collection specifically carried out on December 7, 2024, in Jombor Village, Bendosari District, Sukoharjo Regency, Central Java, from 05:08 AM to 10:00 AM. Observations were made on 19 plants to record blooming times, and data were analyzed descriptively and qualitatively. The results indicated that the blooming times of the Nine O'clock flower varied slightly among the observed plants, with an average blooming time of approximately 2 hours. In conclusion, while the Nine O'clock flower exhibits slight variations in blooming times, further research is recommended, particularly in locations with different altitudes. This study contributes to the understanding of the photoperiodic response of Portulaca grandiflora and its cultivation practices.

Bibliometric Analysis of Studies on Glycemic Index, Diabetes, and Rice Consumption
Get PDFThe prevalence of type 2 diabetes continues to increase along with the consumption pattern of high glycemic index foods, such as white rice, which triggers a spike in blood glucose. Alternatives such as brown and black rice with a lower glycemic index and high fiber, resistant starch, and antioxidant content are considered better in controlling blood sugar. This study analyzes research trends related to glycemic index, rice types, and diabetes using the VOSviewer-based bibliometric method from Scopus data from 2017–2021. The results show an increase in research on this topic with four main clusters: risks of white rice, metabolic syndrome, benefits of brown and black rice, and nutritional approaches in diabetes prevention. This study confirms the potential of brown and black rice as alternative strategies for diabetes management and opens up opportunities for further research in this field
Morphometric Characterization Study of Apis cerana Worker Bees in North Lombok Regency
Get PDFHoneybees (Apis cerana) are one of the indigenous honeybee species of Asia. They serve a crucial function in ecosystems, mostly as pollinators. This study investigates the morphometric characteristics of Apis cerana worker bees in North Lombok Regency, focusing on two beekeeping groups: Harapan Keluarga and Tunas Muda, located in Salut village, Kayangan District North Lombok Regency. Morphometric analysis was conducted on 40 colonies, with measurements taken from eight key body traits: body length, abdomen length, femur length, tibia length, metatarsus length, forewing length, hindwing length, and body weight. Results revealed significant differences between the two locations. Tunas Muda bees exhibited larger morphometric traits with lower coefficient variations, indicating higher population uniformity. Correlation and regression analyses showed that body length, forewing length, and abdomen length strongly influence body weight, with body length having the highest correlation (r = 0.85) and determination coefficient (R2 = 0.722). The study highlights the impact of environmental factors, management practices, and nutritional conditions on bee morphology. These findings provide critical insights for enhancing beekeeping practices, supporting honeybee conservation efforts, and exploring genetic and physiological adaptations in Apis cerana. This research underscores the importance of integrating morphometric analysis into sustainable apiculture and biodiversity conservation strategies in North Lombok
