The Effectiveness of Structured and Guided Inquiry Learning Models in Enhancing Students’ Science Process Skills on Acid-Base Topics in Senior High School
No full textEducation is a key factor in shaping students' character and competence. The 2013 Curriculum highlights not only the development of student character but also the enhancement of scientific competence, including science process skills (SPS). One effective approach to developing SPS is through the application of inquiry-based learning models. This study investigates the differences in students' SPS on acid-base topics by comparing the use of structured inquiry and guided inquiry models. The research employed a random sampling technique, and data were collected using observation sheets and field notes. Field notes were analyzed qualitatively to support and enrich the interpretation of observational and quantitative findings. The quantitative data, obtained from essay-based tests, were analyzed using inferential statistics such as the Shapiro-Wilk normality test, homogeneity test, independent t-test, paired t-test, and N-Gain to evaluate learning improvement in both groups. The effectiveness of each model was determined based on the increase in N-Gain scores from pretest to posttest. The results revealed that inquiry-based learning significantly improved students' SPS, with an increase in the average score from 35.18 to 78.33. Additionally, observation data indicated a steady increase in students’ engagement and participation throughout the learning sessions, highlighting the benefits of inquiry approaches in science education.Pendidikan memegang peranan penting dalam membentuk karakter dan kompetensi siswa.

No full textThis research investigates the effect of forest guava fruit yogurt (Bellucia pentamera Naudin) on the growth of Escherichia coli bacteria in mice (Mus musculus). The study utilized an experimental design with treatment and control groups. Mice were divided into four groups: three treatment groups received forest guava fruit yogurt at concentrations of 5, 10, and 15%, respectively, administered at 0.5 ml per dose daily for 14 days, while the control group was given plain yogurt. E. coli growth was assessed by analyzing fecal samples from each group. The findings revealed that the growth of E. coli bacteria in the mice decreased significantly after administration of forest guava fruit yogurt, with the most pronounced reduction observed in the group receiving the 15% concentration. In contrast, the control group, which received plain yogurt, exhibited a less marked decrease in E. coli growth. These results suggest that forest guava fruit yogurt has a stronger inhibitory effect on E. coli bacteria compared to plain yogurt. In conclusion, forest guava fruit yogurt appears to be an effective natural agent for reducing E. coli growth in mice, potentially offering added health benefits beyond those of conventional yogurt
