Background: Science education at the junior high school level often faces challenges related to students’ limited understanding, low learning interest, and passive participation resulting from conventional teaching approaches.

Research Gap: Although various instructional methods have been implemented in science education, limited attention has been given to understanding how teaching methods and students’ learning interests jointly contribute to the development of basic science skills.

Novelty: This study provides an integrated conceptual analysis of instructional methods and learning interest as interconnected factors influencing students’ basic science skills, emphasizing the importance of aligning teaching strategies with learners’ characteristics and educational objectives.

Methods: This study employed a descriptive qualitative approach based on a literature review of scholarly publications obtained from Google Scholar, electronic libraries, and relevant online and printed sources. Data were analyzed through three stages: data reduction, data presentation, and conclusion drawing.

Results: The findings indicate that instructional methods and learning interest play important roles in developing students’ basic science skills. Experimental, discussion, demonstration, and inquiry-discovery methods support learning outcomes when appropriately adapted to students’ characteristics, learning objectives, material complexity, and instructional time. Furthermore, strong learning interest promotes motivation, active participation, and science process skills.

Conclusion: Appropriate instructional methods combined with strong learning interest contribute to the development of junior high school students’ basic science competencies. Teachers should implement engaging, student-centered strategies that accommodate individual learning needs and strengthen conceptual understanding.

Waste Crisis in Tapak Jedah: Revealing the Ecological Condition of Bengkulu City's Environment and Illustrating Sustainable Solutions

Ristasari Oktavia, Deta Heriani, Deka Apriani — Tue, 09 Jun 2026 00:00:00 +0700

Background: Improper waste disposal poses serious environmental challenges in urban areas, particularly near protected ecosystems. At Tapak Jedah, Bengkulu City, household and industrial waste accumulation threatens the TWA Pantai Panjang-Pulau Baai protected forest, primarily due to inadequate waste collection infrastructure and limited public environmental awareness.

Research Gap: Existing waste management practices have not adequately addressed the environmental consequences of uncontrolled dumping near protected forest areas, particularly regarding pollution pathways, community behavior, and the effectiveness of local waste management regulations.

Novelty: This study provides an integrated assessment of environmental degradation, community waste disposal practices, and regulatory challenges associated with illegal dumping adjacent to a protected coastal forest ecosystem.

Methods: A descriptive qualitative approach was employed through direct field observations and in-depth interviews with local residents and waste pickers. Data were analyzed descriptively to identify waste accumulation patterns, environmental impacts, and community responses.

Results: The findings revealed extensive accumulation of mixed organic and inorganic waste in roadside ravines, contributing to river pollution, leachate generation, unpleasant odors, and potential disease transmission. Despite official prohibition signs, illegal dumping continued. Informal recycling activities provided limited waste recovery but remained insufficient to control increasing waste accumulation.

Conclusion: Uncontrolled dumping at Tapak Jedah threatens environmental quality, public health, and protected forest sustainability. Improving municipal waste collection, enforcing Local Regulation No. 2/2011, and implementing community-based waste segregation, composting, and recycling initiatives are essential for sustainable waste management.

The Effectiveness of Using Discovery Learning Model Assisted by Torso Media on the Topic of Skeletal System towards Learning Outcomes of Grade XI Students at SMAN 3 in Bengkulu City

Sulikah, Widya Amandra, Wahyuni Intan Lestari — Wed, 10 Jun 2026 00:00:00 +0700

Background: Effective biology instruction requires interactive learning strategies to enhance student engagement and conceptual understanding. However, teacher-centered approaches, monotonous instructional methods, and limited learning media contribute to unsatisfactory learning outcomes, particularly in complex topics such as the human skeletal system.

Research Gap: Although Discovery Learning and visual instructional media have been widely implemented, empirical evidence regarding their combined effectiveness in improving skeletal system learning outcomes among senior high school students remains limited, particularly in the context of SMAN 3 Bengkulu City.

Novelty: This study evaluates the integration of Discovery Learning with anatomical torso media, providing empirical evidence of its effectiveness compared with conventional instruction in teaching the skeletal system.

Methods: A quantitative quasi-experimental approach with a control group pretest-posttest design was employed. Forty-eight eleventh-grade science students participated, comprising 24 students in the experimental group and 24 in the control group. Data were collected using multiple-choice tests and analyzed through normality, homogeneity, and independent-samples t-tests.

Results: The experimental group achieved a higher mean posttest score (59.70) than the control group (57.29). Both groups satisfied normality and homogeneity assumptions. However, the calculated t-value (0.5391) was lower than the critical value (1.714) at the 5% significance level, indicating no statistically significant difference between the groups.

Conclusion: Discovery Learning assisted by torso media did not significantly improve skeletal system learning outcomes compared with conventional instruction. Further research should investigate implementation quality, instructional duration, and other factors influencing learning effectiveness.

The Effect of Using Interactive Multimedia-Based Biology Learning Media to Improve Critical Thinking Ability and Student Motivation at SMA Negeri 10 North Bengkulu

Nadiah Giade, Rukiah Lubis, Pariyanto Pariyanto — Thu, 11 Jun 2026 00:00:00 +0700

Background: Critical thinking skills and learning motivation are essential for meaningful biology education. However, conventional teaching approaches often provide limited opportunities for active engagement, analytical reasoning, and independent learning. Interactive multimedia offers an alternative by integrating various digital elements to create engaging and student-centered learning experiences.

Research Gap: Although interactive multimedia has been increasingly incorporated into educational practices, empirical evidence examining its simultaneous effects on students’ critical thinking skills and learning motivation remains limited, particularly in biology education at SMA Negeri 10 Bengkulu Utara.

Novelty: This study simultaneously investigates the effectiveness of interactive multimedia-based biology learning media in enhancing two essential educational outcomes: critical thinking skills and learning motivation, providing context-specific empirical evidence for technology-supported biology instruction.

Methods: A quantitative quasi-experimental approach employing a pretest–posttest non-equivalent control group design was implemented. Two Grade X science classes participated as experimental and control groups. Data were collected through critical thinking assessments and learning motivation questionnaires. Statistical analyses included normality, homogeneity, and hypothesis testing using SPSS.

Results: The findings demonstrated statistically significant differences between the experimental and control groups in critical thinking skills (p = 0.014) and learning motivation (p = 0.047), with both significance values below the 0.05 threshold. These results support the effectiveness of interactive multimedia-based instruction in improving both educational outcomes.

Conclusion: Interactive multimedia-based biology learning media significantly enhance students’ critical thinking skills and learning motivation. Integrating interactive digital resources into biology instruction can support more engaging, participatory, and meaningful learning experiences.
