Abstract

This research aims to determine the effect of using learning media assisted by Smart Apps Creator (SAC) on students' cognitive learning outcomes on the human circulatory system material at SMP Negeri 2 Suwawa. The research method used in this study was an experiment using a One Group Pretest-Posttest Design with a population of all VIII grade students of SMP Negeri 2 Suwawa. The sample consists of 3 classes, namely the experimental class, replication 1 and replication 2, with a purposive sampling technique. Data was obtained by statistical tests and inferential statistics, including normality tests, hypothesis tests, and N-Gain analysis. The results of the average acquisition of class VIII students were greater than the KKTP, shown by the average value of the experimental class of 84.48, replication class 1, 81.14 and replication class 2, 86.45, compared to the KKTP of 75. Based on the hypothesis testing criteria, where the t count in the experimental class was 10.969 compared to the t table of 2.045, replication class 1 obtained a t count of 6.710 with a t table of 2.074, and replication class 2 obtained a t count of 9.569 with a t table of 2.093. It can be concluded that the hypothesis testing in the three classes is that the tcount is greater than the ttable. This can be interpreted as the use of learning media assisted by Smart Apps Creator influences students' cognitive learning outcomes.

Abstract

Chronic stress is a condition that can adversely affect the central nervous system, particularly the brain, by causing damage to neurons in the hippocampal region, which plays a crucial role in memory and learning functions. This study aimed to evaluate the neuroprotective effects of a combined extract of gotu kola leaves (Centella asiatica) and peppermint leaves (Mentha piperita) on the number of normal brain cells in male mice (Mus musculus) subjected to chronic stress. A Completely Randomized Design (CRD) was used with five treatment groups: a negative control group (K−) with no stress and no extract, a positive control group (K+) exposed to stress without extract administration, and three treatment groups (P1, P2, and P3) receiving the combined extract at doses of 100 mg/kg BW, 200 mg/kg BW, and 300 mg/kg BW, respectively. Stress induction was carried out using the immobilization method for 14 consecutive days, followed by extract administration for 35 days. After the treatment period, hippocampal brain tissue was collected and histologically analyzed using Hematoxylin-Eosin (H&E) staining. To assess the treatment effects, One-Way ANOVA was performed. Significant differences were found, Duncan’s Multiple Range Test (DMRT) was conducted at a 5% significance level (p< 0.05). The results demonstrated that administration of the gotu kola and peppermint extract combination significantly reduced neuronal damage and increased the number of normal brain cells. The P3 group (300 mg/kg BW) exhibited the highest number of normal brain cells and the lowest neuronal damage scores, closely resembling the normal condition in the K− group. Therefore, the combination of gotu kola and peppermint leaf extracts shows potential as a natural neuroprotective agent in mitigating the adverse effects of chronic stress on the brain.

Abstract

Science learning in elementary schools often faces challenges in delivering abstract materials such as the solar system, especially due to the limited availability of interactive and interesting media. To overcome this, this study developed Prezi-based learning media assisted by virtual reality and songs as learning aids that are expected to improve students' understanding and learning experience. This study uses a development research method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The research stages include needs analysis, media design, product development, implementation in learning, and evaluation of the effectiveness of the media developed. Prezi media assisted by Virtual Reality and songs were tested through a series of validity and effectiveness tests to assess their quality in supporting learning. The results of expert validation showed that the media developed was categorized as very feasible, with a feasibility percentage reaching 92.85% from media experts and 93.75% from material experts. The validated media was then implemented in class 6 of SDN 6 Wulung with a population of 24 students. The results of the normality test showed a significance value above 0.05, which indicates that the data on all test results that had been carried out were normally distributed. There was an increase in learning scores as evidenced by the paired t-test value, which showed a value of 0.014 in small-scale classes and 0.000 in large-scale classes. In the N-Gain test conducted, the figure was 0.72, which is considered high in small-scale classes, and 0.69, which is considered moderate in large-scale classes. The use of Prezi and virtual reality technology combined with songs has been proven to be able to increase students' grades, interests, and involvement in learning. Thus, this media has the potential to be an innovative alternative in teaching science at the elementary school level. This study recommends further testing with a wider scope to ensure the sustainability and effectiveness of media use in various learning conditions.

Abstract

Scientific Reasoning and Scientific Attitude are important aspects of scientific literacy for students to master because they are directly related to the development of science and technology. This study aims to analyze the effect of the Problem-Based Learning model on students' Scientific Reasoning and Scientific Attitude abilities. This type of research is classified as a quasi-experiment with a non-equivalent control group design. The study population consisted of 13 classes of the 10th grade of MAN 2 Mataram, from which two classes were selected as samples determined by purposive sampling techniques. Data were obtained by administering the Scientific Reasoning test and the Scientific Attitude questionnaire. Data analysis techniques include a comparison of average scores and the Mann-Whitney statistical test. The results showed that the experimental class obtained an average score of 75 points (formal), and the control class obtained a score of 72 points (transitional) on the Scientific Reasoning aspect. On the Scientific Attitude aspect, the experimental class obtained a score of 69 (High) and the control class obtained a score of 63 (Moderate). In addition, the Asympt. sig (2-tailed) value on the Scientific Reasoning aspect is greater than 0.05, which is 0.466, while on the Scientific Attitude aspect it is 0.003 or less than 0.05. Based on these findings, it can be concluded that although the Problem-Based Learning model has a significant effect on Students' Scientific Attitude Ability, its impact on Scientific Reasoning Ability is not statistically significant in the context of this study. This can be influenced by external factors that cannot be fully controlled in the research implementation process.

Abstract

Scientific literacy is an essential competency for prospective science educators in understanding scientific concepts, applying scientific methods, and making decisions based on scientific evidence. This study aims to test the effectiveness of the Ecotourism-Based Field Practicum Model (MPLBE) in improving the scientific literacy of prospective biology teacher students. The subjects of the study were students of the Biology Education study program, FKIP, Mataram University, who took the vertebrate Zoology course. The research design used was a quasi-experiment with a pretest-posttest control group design. The experimental group used the MPLBE model that focused on the study of ecology and conservation of the Megapodius reinwardt bird in the Gunung Tunak and Kerandangan Nature Tourism Parks, while the control group followed conventional practicums in the laboratory. The research instrument was a scientific literacy test that had been validated by experts. Quantitative analysis was performed on the effectiveness of the model using N-Gain and the Mann-Whitney Test. The results of the data analysis showed a significant difference in the increase in scientific literacy scores between the experimental and control groups. These findings indicate that the MPLBE model is effective in improving students' scientific literacy. This model not only strengthens the understanding of biological concepts contextually, but also builds environmental awareness and scientific thinking skills of prospective biology teachers. This study recommends the integration of ecotourism in biology learning as an innovative approach based on local potential.
