Abstract

The Madrasah Science Competition and all other types of Olympic competitions are an important event to achieve achievements and a place for all students to show themselves. Debriefing before the competition is an important activity to carry out as a guide for students to take to the field. However, field facts state that in Man 2 Tanah Datar the coaching of Madrasah Science Competition physics experienced a few problems. Where there is a lack of interest and competitiveness of students at MAN 2 Tanah Datar in participating in Madrasah science competitions and National Student Olympiads in the field of physics at both district/city, provincial and national levels. If you stretch it backwards, this Madrasah Science Competition training is only carried out when it is approaching competition time. Therefore, this coaching can provide changes aimed at increasing students' self-confidence, by ensuring that anyone can take part in competitions, especially in the field of Physics Olympiads, as well as fostering students' interest in taking physics training long before taking part so that these students not only physically ready but also mentally ready. Apart from that, this coaching is carried out so that students are able to compete at any level without feeling burdened due to lack of preparation.

Abstract

This development research aims to produce valid and practical e-modules based on Differentiated Instruction using the STAD model, integrating Al-Qur'an content in the Digestive System topic. This type of research is development research (R&D) using the 4D model (define, design, develop and dissaminate), but the research was limited to the development stage due to constraints in time and funding. This research was conducted in grade XI of senior high school during the 2024/2025 school year. The sample in this study were class XI students totaling 33 people. The e-module was designed using the Canva application then converted using heyzine flipbook and liveworksheets for student worksheets, after completion of the e-module design, it was assessed by material, media and language and design validators using an instrument in the form of a validation questionnaire. The e-module was then tested on a small group to see the level of practicality of the product using the teacher and student response sheet instrument. The sheets were then analyzed using the percentage validation and practicality formulas. Data collection was obtained from the results of the validator questionnaire and student respondents. The results of the study showed that the resulting e-module was very valid with a validation score of 86% and very practical with a response percentage of educators at 100% and students at 89%. Based on the responses of the educator and student questionnaires, the e-learning module is categorized as highly practical and can be used in the learning process.

Abstract

Educators have not widely recognized interactive multimedia, and students show limited interest in the interactive multimedia already provided by educators. This lack of engagement leads to boredom and a decline in students’ enthusiasm for learning biology. The problem statement of this study focuses on the validity and practicality of interactive multimedia based on Articulate storyline. The objective of this research is to determine the results of the validity and practicality of the Articulate storyline-based interactive multimedia. This study employs a Research and Development (R&D) approach using the 4D model (Define, Design, Develop, and Disseminate), although it is limited to the Develop stage. Product validation was conducted by three validators, consisting of two lecturers and one biology teacher. The product trial was carried out by one biology teacher and 35 students. The instruments used in this study include a validity assessment sheet and a practicality assessment sheet. Data analysis was performed using descriptive quantitative methods. The findings indicate that the Articulate storyline-based interactive multimedia was categorized as highly valid, with a percentage of 83.03%. The practicality results also showed that the multimedia was highly practical, with a percentage of 87.84% based on student questionnaires and 93.83% based on educator questionnaires. Therefore, it can be concluded that the development of interactive multimedia based on Articulate storyline can enhance students’ motivation and interest in learning biology.

Abstract

Respirasi adalah salah satu proses metabolisme (katabolisme), reaksi ini menggunakan oksigen untuk memecah senyawa-senyawa yang kompleks menjadi molekul-molekul sederhana seperti yang digunakan sel sebagai energi untuk bertahan hidup. Angiospermae adalah tumbuhan dengan biji tertutup dan biasanya menghasilkan bunga dan buah, sedangkan Gymnospermae adalah tumbuhan dengan biji terbuka. Penelitian ini bertujuan untuk mengetahui perbedaan laju respirasi, pengaruh lingkungan terhadap laju respirasi, peran struktur daun pada laju respirasi dan faktor-faktor yang mempengaruhi laju respirasi tumbuhan Gymnospermae dan Angiospermae.. Alat yang diperlukan untuk kegiatan ini ada timbang analitik, respirometer, beaker glass, pipet tetes, jarum suntik, dan tisu. Bahan yang diperlukan KOH, vaselin, meltilen blue, Oryza sativa, Mimosa pudica, Cycas rumphii, Pinus merkusii. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan empat kali ulangan percobaan. Teknik analisis data yang digunakan adalah Analisis of Variance (ANOVA) untuk mengetahui perbedaan konsumsi oksigen dalam proses respirasi antara tumbuhan Gymnospermae dan Angiospermae. Hasil yang didapatkan rata-rata laju respirasi tumbuhan Gymnospermae 0,33 sedangkan Angiospermae 0,45. Kesimpulan penelitian ini adalah tumbuhan Gymnospermae memiliki laju respirasi yang rendah dibandingkan dengan tumbuhan Angiospermae.

Abstract

Indonesia is a maritime country with tropical forests that possess various natural resources utilized to fulfill needs in clothing, shelter, and medicine. Certain medicinal plants such as Ageratum conyzoides, Mussaenda frondosa, Curcuma longa, and Uncaria gambir have medicinal properties, including antibacterial effects for postpartum infections. The limited knowledge among the public regarding the benefits of traditional medicinal plants is due to restricted dissemination of information through digital media, among other factors.  Therefore, it is crucial that information about the clinical trials of herbal products containing a combination of Ageratum conyzoides, Mussaenda frondosa, Curcuma longa, and Uncaria gambir as postpartum antibacterials is conveyed to the younger generation, especially millennials, and those unfamiliar with the diversity of plants. A non-parametric research design method was employed, testing the pharmacological effects of the herbal product formulation through preliminary data. Data collection involved obtaining responses from 50 participants who used the herbal product, including 15 with vaginal discharge, 10 postpartum individuals, 10 with dysmenorrhea, 5 with postpartum infections, 5 unmarried healthy individuals, and 5 married healthy individuals, using the Wilcoxon test. The research results indicate that the combined herbal formulation significantly affected the test groups with indicators such as vaginal discharge, postpartum without infection, postpartum with infection, dysmenorrhea, and married and healthy individuals, with a significance level of 0.01. These results suggest positive potential. Further analysis reveals that the group without infection complaints did not show a significant impact. In conclusion, the combination formulation demonstrates positive effectiveness in groups with specific complaints related to infection and reproductive disorders. However, the response to the formulation may vary depending on initial health conditions and the characteristics of the target group.
