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.

Abstract

Milkfish (Chanos chanos) scales are a fishery waste rich in chitin and have the potential to be processed into chitosan as a raw material for environmentally friendly bioplastics. This study was conducted using a descriptive qualitative approach through a literature review of seven recent scientific journals. The analysis results show that chitosan derived from milkfish scales has a degree of deacetylation ranging from 44%-92.71%, yield of 20.26%-31.81%, ash content of 0.99%-3.9%, and moisture content of 16%-20%. Physically, chitosan appears as an off-white to yellowish fine powder, odorless, and soluble in acetic acid, thus meeting most of the SNI 7949:2013 standards. This study aims to evaluate the characteristics of milkfish scale-derived chitosan as a raw material for bioplastic production.

Abstract

Abstract: Research on early childhood education at Natuna International Kindergarten reveals challenges in fostering critical thinking and environmental awareness due to traditional teacher-centered learning approaches and reliance on commercial worksheets. To address these issues, the Science, Technology, Engineering, Arts, and Mathematics (STEAM) approach integrated with environmental pollution experiments was implemented using a quasi-experimental design (Randomized Control Group Posttest Only Design with a 2x2 Factorial structure). The research population comprised students at Natuna International Kindergarten during the 2025/2026 academic year, with Group D selected as the experimental class (STEAM-based environmental pollution experiments) and Group C as the control class (conventional learning). Data were gathered through observation checklists and performance assessment rubrics evaluating critical thinking, cognitive problem-solving, and creative output. The findings demonstrated that children taught via the STEAM environmental pollution experiment approach achieved significantly higher learning competencies across cognitive, creative, and manipulative-psychomotor domains compared to those taught with traditional methods. Furthermore, STEAM effectively bridged theoretical environmental awareness with hands-on exploration across varying initial ability levels without significant interaction effects, proving to be an impactful framework for early childhood development in border region educational institutions.

Abstract

This study aimed to explore the in-depth meaning of environmental biology learning from the perspective of SMPIT Natuna Insan Qurani students. Employing a qualitative descriptive phenomenological design, data were gathered through semi-structured in-depth interviews with 12 purposively selected Grade VIII and IX students, participatory classroom/field observations, and instructional documentation. Data analysis followed the Miles and Huberman interactive model encompassing data condensation, data display, and conclusion drawing/verification, supported by source and methodological triangulation. The findings reveal that students interpret environmental biology learning through four interconnected experiential dimensions: (1) cognitive comprehension of ecological interdependence and human-nature harmony; (2) direct affective relevance to daily life, particularly regarding waste reduction and marine ecosystem conservation; (3) behavioral transformation characterized by habitual pro-environmental actions (refusing single-use plastics and maintaining coastal cleanliness); and (4) deep contextual-spiritual internalization linking Natuna's archipelagic environment with Islamic ecological ethics (stewardship / khalīfah fī al-arḍ). Furthermore, students demonstrated a distinct preference for outdoor experiential learning over textbook-bound instruction. This study contributes to contextual science education theory and character education by showing how regional geographical authenticity and religious values synergize to transform abstract biology concepts into tangible ecological consciousness.
