Abstract

The persistent weakness in students' mastery of plant cell concepts indicates a structural problem in conventional science instruction, particularly the lack of direct conceptual construction experiences. The purpose of this study is to determine whether the experiential learning model based on household waste affects students' conceptual understanding of plant cell material. This study examines the impact of experiential learning using improvised microscopes assembled from household waste materials on eighth-grade students at MTs Negeri 3 Kota Palu. The research employed a quasi-experimental method with a non-equivalent control group design. Two classes were purposively selected: class VIII F as the experimental group and class VIII H as the control group. Data were collected through pre-test and post-test essay instruments aligned with conceptual understanding indicators. Statistical analysis showed a significant effect, indicated by an independent sample t-test significance value of 0.000, below the 0.05 level. The experimental group obtained higher mean post-test scores than the control group, demonstrating that experiential learning supported by simple waste-based microscopes effectively improves students' conceptual understanding of plant cells in science learning.

Abstract

The development of digital technology encourages the use of learning media that increase student engagement and problem-solving abilities. However, biology learning about the body's defense system material is still dominated by conventional methods, making it less than optimal in training these abilities. This study aims to develop and test the feasibility of a WordPress-based Problem-Based Learning (PBL) biology learning website. The study employed the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. Research subjects involved media experts, material experts, biology teachers, grade XI students, and teachers from MAN in Bekasi City. Data were collected through validation questionnaires and response questionnaires. The research results show that the learning website has very high validity with percentages of 88.8% (media expert) and 92% (material expert), very high practicality with percentages of 90% (teachers) and 94.7% (students), and 89% effectiveness in the effective category. The PBL-based biology learning website is declared suitable for use as a learning medium on body defense system material.

Abstract

Black pepper contains piperine, which can irritate the digestive organs. Therefore, this study combined black pepper with yogurt containing probiotic bacteria, which are known to play a role in maintaining the balance of microbiota and digestive tract health. The objective of this study was to analyze the histopathology and histomorphometry of the digestive organs, particularly the stomach and small intestine, of mice (Mus musculus) after administration of a combination of black pepper extract and yogurt. The present study was conceptualized as an experimental study, employing a completely randomized design (CRD), encompassing five distinct treatments (distilled water, yogurt, a black pepper extract at a dose of 25, 50, 75 mg/kg BB, and yogurt. The results demonstrated that the thickness of the stomach wall in all treatment groups remained within the normal range. Treatment P2 demonstrated optimal outcomes, exhibiting a thickness of each layer of the stomach wall that ranged between the minimum and maximum values. In the small intestine, all histomorphometric parameters exhibited values that remained within the normal range. The conclusion of this research is combination did not result in an increase in gastric acid secretion and did not induce irritation to the gastric and small intestinal mucosa of mice.

Abstract

Critical thinking skills is one of the essential competencies that must be developed in science learning, especially in the 21st century, as it enables students to analyze, evaluate, and solve problems effectively. Therefore, this study aims to determine the effect of the Think-Pair-Share (TPS) learning model based on three-dimensional (3D) media on the critical thinking skill of seventh-grade students at SMP Negeri 10 Palu on the topic of marine ecosystems. This study employed a quantitative approach with a quasi-experimental method using a non-equivalent control group design. The sample consisted of two classes, namely the experimental and control classes, selected through purposive sampling. The research instrument was an essay test consisting of 10 questions developed based on indicators of critical thinking, including interpretation, analysis, inference, explanation, and self-regulation. Data were analyzed using the Shapiro–Wilk normality test, Levene homogeneity test, and independent sample t-test at a significance level of 0.05. The results showed that the data were normally distributed and homogeneous. The hypothesis testing result obtained a significance value of 0.000 (<0.05), indicating that there was a significant difference in students’ critical thinking skills between the experimental and control classes after the treatment. These findings suggest that the implementation of the Think-Pair-Share learning model based on 3D media has a significant positive effect on improving students’ critical thinking skills.

Abstract

Science learning at the junior high school level plays an important role in developing students’ science process skills as the foundation of scientific literacy. However, classroom practices still tend to emphasize content mastery rather than learning processes and systematic skill development. This study aimed to analyze the implementation of the 5E Learning Cycle model in acid–base learning, focusing on the development of students’ science process skills at each learning stage. This research employed a descriptive qualitative approach involving Grade VII students. Data were collected through classroom observations, documentation of student activities, and analysis of science process skills that emerged during learning, and were analyzed thematically. The results indicate that the 5E Learning Cycle supports student-centered learning and facilitates the gradual development of science process skills. The Engagement stage builds students’ cognitive readiness and motivation. Exploration becomes the main phase for developing basic process skills through experimental activities. Explanation and Elaboration support data interpretation, communication, and application of concepts, while Evaluation functions as a reflection on students’ understanding and learning processes. The study concludes that the 5E Learning Cycle can be effectively implemented in authentic classroom contexts with limited resources and provides both theoretical and practical contributions to process-oriented science learning.

Abstract

Twenty-first-century science education requires not only conceptual mastery but also the development of scientific process skills and critical thinking. Laboratory work plays a central role in achieving these goals; however, its effectiveness is often limited by “cookbook-style” procedures that fail to promote deep cognitive engagement. This study aimed to explore students’ perceptions of science practicums as indicators of Meaningful Learning (Pembelajaran Bermakna/PBM). Using a qualitative approach with an exploratory case study design, this research involved twelve purposively selected Grade VIII students. Data were collected through in-depth interviews, non-participant observation, and documentation, and were analyzed using thematic analysis. The findings indicate that students perceive meaningful learning as conceptual understanding that can be applied to everyday life rather than mere memorization. Science practicums were viewed as an effective means of achieving PBM, particularly due to the quality of teacher guidance, clear instructions, and opportunities for group collaboration. Although limited laboratory equipment and materials were identified as the main constraints, these limitations did not substantially hinder students’ conceptual understanding. The study concludes that strong pedagogical interactions can bridge hands-on and minds-on learning and support the implementation of competency-based curricula.

Abstract

Keratin waste is highly recalcitrant due to its complex protein structure, requiring efficient biodegradation strategies. This study aimed to evaluate and optimize keratinase production of thermophilic Bacillus licheniformis AAL3 isolated from the Air Putih hot spring, Lebong, Bengkulu. Qualitative keratinolytic activity was determined using feather meal agar, while quantitative enzyme activity was measured spectrophotometrically based on tyrosine release. The isolate exhibited a higher keratinolytic index (5.0) compared to B. licheniformis SCL2 (1.5). Quantitative analysis showed that AAL3 produced higher cell density (8.9 × 10? CFU/mL) and keratinase activity (1.0074 U/mL). Optimization studies revealed that maximum keratinase production occurred at 60 °C and pH 9. Among the tested carbon sources, 1% glucose resulted in the highest cell growth and enzyme activity, whereas 0.4% peptone was the most effective nitrogen source. The results demonstrate a strong positive correlation between bacterial growth and keratinase production. These findings indicate that B. licheniformis AAL3 has significant potential as a thermophilic keratinase producer for biotechnological applications, particularly in keratin waste biodegradation.
