Abstract

Learning Natural and Social Sciences integrated with regional culture in elementary schools still faces various obstacles, resulting in low student learning outcomes in the cognitive, affective, and psychomotor domains. This problem indicates a gap between the demands of active, meaningful learning and the underdeveloped learning practices, with minimal use of digital media. Therefore, this study aims to determine improvements in fifth-grade student learning outcomes through the implementation of the Discovery Learning model supported by Canva-based presentation media. This study used a collaborative Classroom Action Research (CAR) method, implemented in two cycles, with stages of planning, implementation, observation, and reflection. The research subjects were fifth-grade elementary school students. Data collection techniques included tests, observation, and documentation. Data analysis was conducted using quantitative descriptive techniques, calculating the average learning outcome score for each cycle. The results showed improvements in all domains. The average cognitive learning outcome score increased from 64.81 in Cycle I to 91.48 in Cycle II. The affective domain increased from 66.48 to 90.00, while the psychomotor domain increased from 66.39 to 82.00. This increase occurred because the Discovery Learning model supported by Canva was able to create more interactive learning, encourage student activeness in discovering concepts, and facilitate the visualization of material in an interesting and contextual way. Thus, it can be concluded that the implementation of the Discovery Learning model, supported by Canva, is effective in improving student learning outcomes across the cognitive, affective, and psychomotor domains. The implication of this study is the need for teachers to continuously integrate innovative learning models and digital media to create more meaningful, student-tailored learning.

Abstract

Low biology learning outcomes are often linked to conventional teacher-centered instruction, which limits student engagement and active participation. This study was conducted to address these challenges by examining the effect of Brain-Based Learning on students’ biology achievement. The main objective was to determine whether this innovative approach could significantly improve learning outcomes compared to traditional methods. A quasi-experimental design was employed, specifically the pretest-posttest control-group design. The sample was selected using purposive sampling, resulting in two classes: an experimental class that received Brain-Based Learning treatment and a control class that continued with conventional instruction. Data collection techniques included biology achievement tests administered before and after the intervention, complemented by classroom observations to monitor the implementation process and student involvement. Data analysis was carried out using an independent sample t-test to assess the significance of differences between the two groups. The results revealed a clear and significant effect of Brain-Based Learning on students’ biology learning outcomes, as indicated by a p-value of 0.000, which is below the 0.05 threshold. The average post-test score in the experimental class was 78.45, while the control class scored only 49.32. These findings demonstrate that Brain-Based Learning is more effective than conventional methods in enhancing students’ understanding of biological concepts. In conclusion, Brain-Based Learning significantly improves biology learning outcomes and fosters more active, meaningful, and engaging learning experiences. The practical implication of this study is that teachers should consider adopting Brain-Based Learning as an innovative instructional strategy to enhance the quality of biology education. By shifting from teacher-centered to student-centered approaches, educators can create learning environments that better support achievement and long-term retention of scientific knowledge.

Abstract

Food security is a global strategic issue that requires science and technology-based innovations, one of which is plant tissue culture biotechnology. However, tissue culture is abstract and difficult for students to understand because it involves microscopic processes that cannot be directly observed. Therefore, instructional media that can visually illustrate these concepts are needed. This study aimed to develop an animated video on plant tissue culture, based on visual literacy principles and to evaluate its feasibility and effectiveness in biotechnology learning related to food security. This research employed a Research and Development (R&D) approach, using a modified 4D model through the development stage. The trial was conducted with 20 ninth-grade junior high school students who had not previously used animated video media in tissue culture learning and were willing to participate in the entire sequence of learning activities, using a one-group pretest-posttest design. Research instruments included expert validation sheets, student response questionnaires, and pretest and posttest assessments. Data were analyzed using descriptive and inferential statistics, including the Wilcoxon Signed Rank Test and N-gain analysis. The study results showed that the developed media was highly feasible, with an overall validation score of 98.89% from six validators, all of whom were media and material experts, who categorized it as "very feasible." Student responses were also very positive, with 81.2% in favor. Effectiveness analysis showed a significant improvement from pretest to posttest scores (p < 0.001), with an N-gain of 0.7722 (high category), indicating that the media effectively enhanced students’ conceptual understanding of plant tissue culture. The novelty of this study lies in integrating visual literacy indicators and the food security context, and utilizing Artificial Intelligence technology to develop educational animation. These findings suggest that AI-based animated media can concretize complex biotechnology concepts and improve the quality of science learning.

Abstract

Biology, as a branch of natural science, plays an important role in providing students with an understanding of humans, the environment, and factors that influence health. This study aimed to determine the effectiveness of Screening, Visualization, Elaboration, and Reflection (SrVER)-based learning modules integrated with Augmented Reality (AR) in improving students’ health literacy in circulatory system learning at SMAN 3 Mataram. This study used a quantitative quasi-experimental design with a Non-Equivalent Control Group. The study involved 50 eleventh-grade students of SMAN 3 Mataram in the 2025/2026 academic year who studied the circulatory system material using a purposive sampling technique. Data were collected using multiple-choice questions. The data analyzed in this study were the N-Gain test and the Mann-Whitney test. The results of the prerequisite test showed that the data did not meet the assumptions of normality or homogeneity of variance; therefore, the analysis was conducted using the nonparametric Mann–Whitney U test on the N-gain score. The study found that the experimental class had an N-Gain of 0.8, in the high category, while the control class had an N-Gain of 0.3, in the low category. In addition, the Mann-Whitney test obtained an Asymp. Sig. (2-tailed) value of 0.000 <0.05, which means there is a significant difference in the post-test scores of the experimental and control classes. Thus, the null hypothesis (H0), which states that there is no effectiveness in using the SrVER-based learning module integrated with Augmented Reality (AR), is rejected. In contrast, the alternative hypothesis (Ha) is accepted. It can be said that using the SrVER-based learning module integrated with Augmented Reality (AR) to improve students' health literacy in the circulatory system material at SMAN 3 Mataram is effective.

Abstract

Biology learning requires students to have self-efficacy, namely, confidence in their abilities to solve learning problems and complete certain tasks. SrVER is a learning model that emphasizes a visual learning style, which adapts the main principles in the teaching and learning process, namely Screening, Visualization, Elaboration, and Reflection. The SrVER model can be considered one approach with the potential to improve student self-efficacy. The purpose of this study was to determine the effectiveness of SrVER-based learning modules integrated with Augmented Reality (AR) on student self-efficacy in excretory system material at SMAN 2 Mataram. This study used a quantitative experimental method with a non-equivalent control group design and purposive sampling. The experimental group was given treatment, namely the use of the AR-integrated SrVER learning module, while the control class, the learning was as usual for teachers. Data collection in this study was carried out by distributing questionnaires to students, totaling 28 questions. Data were analyzed using the Mann–Whitney U test because the data were not normally distributed. The results of the study obtained an Asymp. Sig. (2-tailed) value of 0.003, which indicates that the value is <0.05, so that Ha is accepted and Ho is rejected, so that it can be interpreted that there is an effectiveness of the use of the SrVER learning module integrated with augmented reality on student self-ability in the excretory system material for class XI of SMAN 2 Mataram. These findings indicate that integrating SrVER and AR can support more interactive and meaningful biology learning.

Abstract

The widespread integration of digital technology into biology education has created a pressing need for learning platforms that simultaneously engage students and cultivate higher-order thinking skills. Despite the growing adoption of virtual environments and discovery-based learning models, empirical evidence examining their combined pedagogical effect on critical thinking within biodiversity topics remains scarce. This study aimed to evaluate the effectiveness of Metasteps-Based Virtual Biodiversity Learning in improving 10th-grade students' critical thinking skills regarding biodiversity threats and conservation efforts. A pre-experimental approach was employed using a one-group pretest-posttest design, involving 36 tenth-grade students at a private high school in Bandung Regency during the 2025/2026 academic year. The primary instrument was a 15-item multiple-choice critical-thinking test developed based on Facione’s indicators, encompassing interpretation, analysis, inference, evaluation, explanation, and self-regulation. Data normality was assessed using the Shapiro–Wilk test; because both pretest and posttest scores were non-normally distributed (p < 0.05), the Wilcoxon Signed-Rank Test was applied as the inferential statistical procedure. Effect size was calculated using the formula r = Z divided by the square root of N to quantify the practical significance of the intervention. Results revealed a statistically significant improvement in critical thinking skills from pretest to posttest (Z = –4.729; p < 0.001), with an effect size of 0.78, classified as moderate according to Cohen’s criteria. Indicator-level analysis showed gains across all six dimensions, with the largest improvements observed in analysis and explanation (23 percentage points each). These findings indicate that integrating a three-dimensional virtual biodiversity environment with structured stages of discovery learning can yield meaningful gains in students’ critical thinking. The study provides practical evidence for the use of immersive virtual platforms as an alternative science-learning strategy aligned with 21st-century educational demands.

Abstract

Science learning requires innovative strategies that actively engage students in the learning process. However, classroom learning is often still teacher-centered, resulting in low student participation and unsatisfactory learning outcomes. This study aimed to analyze the effect of using Educaplay media integrated with the Team Games Tournament (TGT) learning model on students’ learning outcomes in the topic of classification of living things. The research employed a quasi-experimental design with a nonequivalent control group. The sample comprised 62 seventh-grade students selected through purposive sampling, divided into an experimental and a control class. The experimental class received instruction using the TGT model assisted by Educaplay, while the control class used the TGT model without Educaplay. Data were collected using validated cognitive achievement tests and analysed using descriptive statistics, normality and homogeneity tests, and independent-samples t-tests. The results showed that the experimental class achieved a higher mean posttest score (74.35) than the control class (56.77). Hypothesis testing revealed a significance value (Sig. 2-tailed) of < 0.001 < 0.05, indicating that the use of Educaplay-assisted TGT significantly affected students’ learning outcomes. Therefore, integrating Educaplay with the TGT learning model can improve students’ engagement and science learning outcomes. These findings suggest that integrating Educaplay into cooperative learning can serve as an effective digital learning strategy to enhance student achievement and support more engaging science instruction in junior high schools.

Abstract

Aedes aegypti and Aedes albopictus are mosquito vectors that are thought to be the cause of Dengue Hemorrhagic Fever (DHF), especially in Indonesia, because it is a tropical climate area, and the rate of disease transmission due to mosquitoes is high. Besides that, Indonesia is known for being rich in plant species that can be used as natural larvicides. Turmeric rhizome (Curcuma longa L.) is a plant that contains secondary metabolites that can be used as larvicide. The purpose of this study was to test the effectiveness of turmeric rhizome infusion (Curcuma longa L.) on the mortality of Aedes aegypti and Aedes albopictus mosquito larvae. In this study, turmeric rhizome (Curcuma longa L.) infusion was used at concentrations of 25%, 50%, and 75%, as well as the positive control (abate drug) and the negative control (aquadest). The Kruskal–Wallis test results showed a probability value (p-value) of 0.001 (p<0.05) in both Aedes aegypti and Aedes albopictus larvae, indicating a significant difference between treatment groups, especially between the positive control and the 75% concentration of turmeric rhizome infusion treatment. Furthermore, the Mann–Whitney U test results showed that the 75% concentration exhibited a larvicidal effect against both mosquito larval types. Turmeric rhizome infusion (Curcuma longa L.) was proven to have inhibitory activity against Aedes sp. larvae, although its effectiveness was still lower than that of chemical larvicides. However, the community considered the use of turmeric rhizome infusion safer, simpler, and easier to apply than natural larvicides. Therefore, this study can serve as a reference for developing natural larvicidal agents from turmeric rhizomes (Curcuma longa L.).

Abstract

Water quality in Indonesia has been declining from year to year. One of the bodies of water experiencing declining water quality is the river. The decline in water quality, accompanied by bacterial contamination, contributes to various diseases linked to contaminated water. The Laju River is one of the large rivers located in the heart of Dompu City. The many activities of residents around the river are one of the sources of pollution in the Laju River. The purpose of this study is to determine the presence and number of Coliform bacteria and Escherichia coli. This type of research is Qualitative Descriptive research. Laju river water samples were taken from the upstream, middle and downstream sections. Based on the examination results, the highest number of Coliform bacteria was in the middle section of the river, namely 16,800 CFU/ 100 ml, and the highest number of Escherichia coli was in the upstream section of the river, namely 17,000 CFU/100 ml. The number of Coliform and Escherichia coli in Laju River water exceeds the value of the Class II River Water Quality Standards set by Government Regulation No. 22 of 2021. Reducing the levels of Coliform and Escherichia coli in river water requires a gradual approach, starting with physical treatment and progressing to chemical disinfection. Controlling the levels of Escherichia coli and Coliform in water is essential because these bacteria are the main indicators of dangerous pathogen contamination, serve as a standard for water quality suitability, and help detect sanitation damage.

Abstract

Mosquito coil smoke contains reactive oxygen species (ROS) that may induce oxidative stress and increase malondialdehyde (MDA) levels as a marker of lipid peroxidation and cellular damage. Tomato juice contains lycopene, a natural antioxidant that may help reduce oxidative stress from free radicals. This study aimed to evaluate the effect of tomato juice administration on testicular MDA levels in rats exposed to mosquito coil smoke. This laboratory experimental study used a Completely Randomized Design (CRD) involving 20 male Rattus norvegicus rats randomly divided into four groups: negative control, positive control (mosquito coil smoke exposure for 8 hours/day), and two treatment groups receiving smoke exposure combined with tomato juice at doses of 3.81 g/day and 7.62 g/day for 30 days. Testicular MDA levels were measured using the Thiobarbituric Acid Reactive Substances (TBARS) method with a UV-Vis spectrophotometer. Data were analyzed using one-way ANOVA followed by LSD post hoc test with a significance level of p < 0.05. The results showed that the positive control group had the highest testicular MDA levels, whereas administration of tomato juice significantly reduced MDA levels in the treatment groups. The greatest reduction was observed in the group receiving 7.62 g/day of tomato juice, with MDA levels approaching those of the negative control group. In conclusion, exposure to mosquito coil smoke increased testicular MDA levels, while tomato juice administration, particularly at higher doses, reduced oxidative stress-induced lipid peroxidation. These findings suggest that tomato juice has potential as a natural antioxidant against oxidative damage from mosquito coil smoke exposure.
