Abstract

This study aims to determine the effect of Etlingera hemisphaerica (honje) fruit juice on the recovery of erythrocyte and leukocyte counts in mice (Mus musculus) exposed to mercuric chloride (HgCl₂). The method used was an experimental design using male mice as test animals, divided into three groups: K1 (control), K2 (honje juice 0.3 mL/20 g BW for 3 days), and K3 (HgCl₂ 5 mg/kg BW + honje juice 0.3 mL/20 g BW for 3 days). The observed parameters were the number of erythrocytes and leukocytes before and after treatment. The results showed that honje juice administration increased the erythrocyte count in group K2, while in group K3, erythrocyte recovery was affected by mercury exposure, making the honje juice less effective, although the values remained within the normal range compared to the control group. In leukocyte count, group K2 showed a stabilizing effect, whereas group K3 experienced an increase due to HgCl₂ exposure. In conclusion, Etlingera hemisphaerica fruit juice has potential as a phytotherapy agent to repair hematological damage caused by heavy metal toxicity, although its effectiveness is influenced by the metabolic condition of the mice and the high concentration of mercury. Keywords: Etlingera hemisphaerica, Erythrocytes, Leukocytes, Mice, Mercuric Chloride

Abstract

This study aims to implement the Digital Game-Based Learning (DGBL) model through the EcoFarm Challenge educational game to improve students' problem-solving skills. This research uses a research and development (R&D) approach combined with a quasi-experimental design and a one-group pretest-posttest design involving 18 students. Data analysis was performed using the Shapiro–Wilk normality test and the Wilcoxon Signed-Rank Test. The results showed that the data were not normally distributed (p < 0.05), so the Wilcoxon test was used. The test results showed a significant difference between the pretest and posttest (Z = -2.312; p = 0.021) with a large effect size (r = -0.788). Data visualization using a raincloud plot also showed an upward trend in scores despite individual variation. These results indicate that the DGBL model is effective in improving students' problem-solving skills through interactive, simulation-based learning experiences.

Abstract

Mastery of biological scientific terms often poses a challenge for students in General Biology courses. This study aimed to develop GLOSABIO, an Android-based learning application designed to improve students’ understanding of biological scientific terminology. This research employed the Research and Development (R&D) method using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The research subjects included 33 students from the Science Education Study Program at the University of Bengkulu. Product validation was conducted by material and media experts using validation sheets, while student response questionnaires and a 33-item matching test were used to measure practicality and effectiveness. Data were analyzed using descriptive quantitative analysis, percentage analysis, and N-Gain analysis. The validation results showed that GLOSABIO was highly valid (93%), while practicality testing indicated that the application was very practical (89%). Students’ average scores increased from 51.97 in the pretest to 86.41 in the posttest, with an N-Gain score of 0.717 categorized as high/effective. The paired sample t-test showed a significant difference between pretest and posttest scores (p < .001), with a very large effect size (Cohen’s d = 2.45). These findings demonstrate that GLOSABIO is valid, practical, and effective in enhancing students’ mastery of biological scientific terminology.

Abstract

Background: The integration of environmental issues into junior high school science learning remains limited, reducing opportunities for students to develop scientific literacy through contextual, practical activities. Although science literacy-oriented modules have been developed, practicum modules that focus on converting leachate into liquid organic fertilizer as a contextual learning resource for scientific literacy are still rarely reported.Aim: This investigation sought to create and assess the practicability of a leachate-processing practicum module intended to support scientific literacy among students in junior high school. Methods: The investigation utilized a research and development methodology employing the 4D model, which encompasses the Define, Design, and Develop phases. A restricted implementation was carried out utilizing a one-group pretest–posttest framework. Validation involved four experts. Participants were Grade IX students: 27 completed the response questionnaire and 24 the scientific literacy test, reflecting attendance during the respective data collection sessions. Data were examined utilizing Aiken’s V, descriptive statistics, N-gain, and a paired-sample t-test.Results: The module demonstrated high validity with an Aiken’s V score of 0.961. Student responses exceeded 90%, indicating very positive perceptions of the module. Scientific literacy scores demonstrated an increase from a mean pretest score of 59.17 to a mean posttest score of 89.58, accompanied by an average N-gain of 0.79, which is classified within the high category. Significant differences were found between pretest and posttest scores (p < 0.001).Conclusion: The developed practicum module is feasible for use in contextual science learning and demonstrates promising effects on students’ scientific literacy in a limited implementation setting.

Abstract

This study aimed to determine the effect of administering chitosan nanoparticles loaded with Jatropha multifida L. stem extract on the erythrocyte count of Mus musculus infected with Plasmodium berghei as well as their characterization results. The method used was the preparation of chitosan nanoparticles loaded with J. multifida L. stem extract using the ionic gelation method. Characterization results using Particle Size Analysis (PSA) showed that the chitosan nanoparticles loaded with J. multifida L. stem extract had an average particle size of 567.12 nm with a polydispersity index (PDI) value of 0.11, while characterization using X-ray diffraction (XRD) showed the highest peak at a 2θ angle of 28.68°. The results indicated differences in the effects of varying concentrations of chitosan nanoparticles loaded with J. multifida L. stem extract on erythrocyte counts. The conclusion of this study is that the most effective dose of chitosan nanoparticles loaded with J. multifida L. stem extract was 0.028 g/kg body weight, followed by the administration of crude J. multifida L. stem extract at the same dose.   Keywords: Erythrocytes, Jatropha multifida L., Chitosan, Nanoparticles, Particle Size Analysis, Plasmodium berghei, X-ray Diffraction

Abstract

This study aims to determine the agreement between experimental data from uniform linear motion and uniformly accelerated linear motion experiments using a line-following robot and linear motion theory. The novelty lies in providing empirical evidence on the scientific suitability of line-following robots for representing different types of linear motion. The study validates the robot’s ability to represent GLB, accelerated GLBB, and decelerated GLBB by evaluating the agreement between experimental and theoretical velocity-time (v-t) characteristics before implementation as a physics learning tool. The method involved conducting linear motion experiments, plotting experimental data on v-t graphs, and comparing them with theoretical graphs. Three types of motion were investigated: GLB, accelerated GLBB, and decelerated GLBB. The accelerated and decelerated GLBB experiments were conducted at elevation angles of 13°, 10°, 7°, and 4°. The results show that the GLB and decelerated GLBB experiments generally align with the corresponding motion concepts. The GLB experiment achieved a mean R² value of 1, indicating very high agreement with linear motion theory. Decelerated GLBB achieved a mean R² value of 0.8618, with very high agreement at elevation angles of 10°, 7°, and 4°. In contrast, the accelerated GLBB experiment produced a v-t graph inconsistent with theoretical expectations because the robot’s speed remained nearly constant rather than increasing uniformly. Therefore, the line-following robot is suitable for representing GLB and decelerated GLBB, particularly at elevation angles of 10°, 7°, and 4°. However, it does not adequately represent accelerated GLBB and requires further modification before use for this motion type.
