Abstract

This research aims to analyse the successful implementation of the discovery learning model in mathematics learning at the tertiary level. Discovery learning is one of the innovative learning models that encourages students to be actively involved in the learning process by discovering mathematical concepts by themselves. actively in the learning process by discovering mathematical concepts independently. independently. The research method used is a case study on a mathematics study programme in a university. study programme in a university. Data were collected through classroom observation, interviews with classroom observation, interviews with lecturers and students, and document analysis. The results The results showed that the implementation of discovery learning in mathematics learning in higher education is generally successful in improving students' conceptual understanding, critical thinking skills, and motivation to learn. learning. However, there are some challenges such as the lack of skills students' skills in independent learning, limited time allocation for learning, and lecturers' readiness in designing and managing discovery learning, and lecturers' readiness in designing and managing discovery learning. Research This research provides practical implications for lecturers and higher education institutions in developing and implementing discovery learning in developing and implementing an effective discovery learning model in mathematics courses. learning model in mathematics courses. Recommendations for future research is to explore student mentoring strategies and professional development of lecturers in the implementation of innovative learning models.

Abstract

Background. Audio-visual media is media that contains elements of sound and images. It is useful for conveying information, knowledge, ideas, ideas in a more interesting way. The proper use of audiovisual media in accordance with the needs in education will be able to improve learning achievement. Audio visual media will help students in developing logical, critical, and creative thinking skills in solving problems. The use of audiovisual media in learning mathematics can improve student achievement in elementary school. This can be achieved as long as the use is effective and efficient. Purpose. This study aims to measure the effectiveness of using audio-visual media in improving student achievement in mathematics learning in elementary schools. This research will also be useful to find out the factors that influence the success of using audio-visual media. In addition, it is also to find out how far audiovisual media can help students in understanding mathematical concepts, increase learning motivation, and develop logical, critical, and creative thinking skills. Method. The method used in this research is quantitative. Quantitative method is a way of presenting data in the form of numbers. The data obtained is the result of the acquisition of responses. The data is taken from the distribution of questionnaires containing questions related to the effectiveness of the use of audio-visual media in improving student achievement in mathematics learning at the elementary school level. Results. The results of this study state that the use of audio visual in math learning in elementary schools can improve student achievement. The use of audiovisual media has a positive effectiveness in learning mathematics in elementary schools. The use of audiovisual media can improve student learning outcomes, concept understanding, ability to analyze, and interest in learning. However, the use of this media must also pay attention to certain factors in order to be effective. Conclusion This research can be concluded that audio visual media as a learning medium that contains elements of sound and images will be able to be used to convey information, knowledge, ideas, or ideas more interestingly. The use of audio-visual media in learning mathematics will help in improving students' concept understanding, interest, and learning outcomes.

Abstract

This study aimed to evaluate the antioxidant effect of a syrup combining Hibiscus sabdariffa L. (roselle) and Ocimum sanctum L. (basil) extracts in male rats exposed to oxidative stress induced by used cooking oil (UCO). A randomized controlled design was applied using six treatment groups, including single and combined extract syrups. Plasma malondialdehyde (MDA) levels, an indicator of lipid peroxidation, were measured before induction, after UCO exposure, and following treatment. Results showed a significant rise in MDA levels after UCO induction, confirming oxidative stress. Administration of roselle–basil syrup markedly reduced plasma MDA compared with the induced control (p < 0.05). The optimal formulation achieved up to a 96–97% reduction in MDA levels, indicating strong antioxidant efficacy. This effect is attributed to the synergistic action of anthocyanins from roselle and eugenol and rosmarinic acid from basil, which act as radical scavengers and metal chelators. These findings validate the synergistic potential of the roselle–basil combination in mitigating oxidative stress and lipid peroxidation. The study highlights its promise as a natural, safe, and locally sourced antioxidant formulation, offering a foundation for developing functional beverages or nutraceutical products aimed at preventing oxidative damage from dietary lipid oxidation.

Abstract

The rapid growth of biomedical research has generated massive volumes of data, creating significant computational challenges. Traditional high-performance computing systems struggle to efficiently process, analyze, and manage such large-scale datasets. Grid computing, with its distributed architecture, offers a promising solution by enabling scalable and cost-effective data processing. This study explores the optimization of grid computing frameworks for big data processing in biomedical research, focusing on enhancing computational efficiency, scalability, and fault tolerance. The research aimed to evaluate the performance of optimized grid computing systems in processing diverse biomedical datasets, including genomic, proteomic, and imaging data. A combination of experimental and comparative approaches was employed, integrating grid computing frameworks such as Apache Hadoop and Globus Toolkit with biomedical data pipelines. Key metrics, including processing time, resource utilization, and error rates, were analyzed to assess the system’s performance. The findings demonstrated that optimized grid computing systems reduced processing time by an average of 35% compared to traditional methods while maintaining high accuracy. Scalability tests confirmed the framework’s ability to handle datasets up to 15 times larger without significant performance degradation. Fault tolerance improved through adaptive resource allocation, minimizing workflow interruptions. The study concludes that optimized grid computing is a transformative approach for big data processing in biomedical research. Its ability to enhance computational efficiency and scalability positions it as a crucial tool for addressing the growing data demands of modern biomedical science.
