Abstract

The ethnopharmacological study aims to document and analyze the use of medicinal plants by the Dayak Bakumpai community in Bahalayung Village, Barito Kuala Regency. This research employs a qualitative descriptive approach, utilizing in-depth interviews, participatory observation, and documentation methods. Key informants include community leaders, traditional healers, and local users of medicinal plants. The findings reveal that the Dayak Bakumpai community utilizes a variety of local plants to treat ailments such as fever, wounds, digestive disorders, and skin diseases. A total of 15 medicinal plant species were identified as commonly used; however, knowledge about their medicinal applications remains limited. This knowledge is traditionally passed down orally across generations and is deeply rooted in the community's cultural practices. The presence of active compounds such as flavonoids, alkaloids, and tannins in several plants indicates significant pharmacological potential. This study underscores the importance of preserving traditional knowledge as a means of safeguarding biodiversity and cultural heritage. Additionally, further research is needed to scientifically validate the safety and efficacy of these medicinal plants, supporting the development of evidence-based traditional medicine.

Abstract

This research was conducted due to the students’ low learning competence in biology in class VII of SMPN 1 Bunguran Timur. The problem was caused by the students who were passive, had less curiosity, and were unable to correlate between theory and practice, and the limited learning sources available to direct the students to solve problems. On of the ways used to cope with this problem was by applying vee diagram in Problem Based Learning (PBL) model. The purpose of this research was to reveal whether the biology learning competence of the students taught by using vee diagram in PBL model was higher than that of students taught by using PBL model. The quasi-experimental with Randomized Control Group Posttest Only Design and Factorial 2x2 is used in the research. The research were all of the students of class VII of SMPN 1 Bunguran Timur enrolled in the 2023/2024 Academic Year. The sample are taken y purposive sampling technique, VII8 class as an experimental class and VII6 class as an control class. Cognitive instrument using tested objective test as many as 35 items, while affective and psycjomotor instruments using observation sheet. The result showed that the implementation that the implementation of vee diagram in PBL on the pollution and environmental damage topics was more higher than that of students taught by using PBL model, whereas both of them (students with high and low early ability) had higher cognitive competence, and there is no interaction between learning model with early ability toward student learning competence.

Abstract

Problem-Based Learning (PBL) is a learning model that focuses on solving real-world problems to foster students’ critical and analytical thinking skills. Meanwhile, Project-Based Learning (PjBL) emphasizes students’ involvement in completing projects that produce tangible products, thereby enhancing collaboration and creativity. This study aims to compare the effects of PBL and PjBL on students' cognitive learning outcomes in science education at SMP Negeri 2 Kota Bengkulu. A quasi-experimental method with a nonequivalent control group pretest-posttest design was employed. The research sample consisted of 116 students, comprising 39 students in the PBL class, 38 in the PjBL class, and 39 in the control class. Data were collected using cognitive learning outcome tests and analyzed with the Kruskal-Wallis and Mann-Whitney U tests. The results revealed significant differences in students’ cognitive learning outcomes between the PBL and PjBL models. PBL was found to be more effective in enhancing students’ cognitive learning outcomes compared to PjBL. These findings suggest that problem-based learning can improve the effectiveness of science education.

Abstract

This study aims to determine the effect of augmented reality-based laboratory guidelines on students' science literacy and interest in learning. Two classes were involved as the experimental class and the control class with different treatments. The experimental class applied Augmented Reality-based laboratory guidelines, while the control class did not. The research sample was class X IPA 2 as the experimental class and class X IPA 3 as the control class. The instruments used were essay questions to measure literacy skills and questionnaires to measure learning interest. The results showed that there was a significant effect of Augmented Reality-based practicum guides on students' science literacy skills, with a sig value < alpha value, namely 0.000 < 0.05, or tcount > ttable, namely 4.161 > 2.010. In addition, there was also a significant effect on students' interest in learning, with a sig value < alpha value, namely 0.00 < 0.05 or tcount > ttable, namely 4.790 > 2.010.

Abstract

Thalassemia is an autosomal recessive genetic disorder that remains a significant public health concern in Indonesia; consequently, early detection of carriers is crucial to prevent the birth of children with thalassemia major. This study aims to analyze the risk of thalassemia among Biology students at the Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Riau, utilizing a simplified laboratory screening approach. The research involved 30 students who participated in genetic risk questionnaires, hemoglobin level assessments using digital hemometers, and erythrocyte counts via hemocytometers. The findings revealed a questionnaire risk score of 0.07 (categorized as very low), a mean hemoglobin level of 12.73 g/dL, and an erythrocyte count of 5.22 million cells/µL, both of which fall within normal physiological ranges. These results indicate that the risk of thalassemia among Biology students at FMIPA Universitas Riau is remarkably low. Simple screening through questionnaires, hemoglobin levels, and erythrocyte counts can serve as an effective method for both educational purposes and the preliminary screening of thalassemia carrier risk in students.
