Abstract

This study aims to determine the effect of giving independent assignments on student learning outcomes in the Histology course. The method used was a quasi-experimental design with a pretest-posttest control group design. The study subjects consisted of two classes: a treatment class given independent assignments and a control class without similar treatment. Data were collected through pretests and posttests, then analyzed using paired t-tests and homogeneity of variance tests. The results showed a significant difference between pretest and posttest scores in the treatment class (p = 0.000 < 0.05), while the control class showed no significant difference (p = 0.348 > 0.05). These findings indicate that giving independent assignments can significantly improve student learning outcomes. Thus, independent assignments are effectively implemented as a learning strategy in the Histology course to train students' independence, responsibility, and critical thinking skills.

Abstract

Active student participation is the direct involvement of students in the learning process which includes indicators, such as: giving opinions, giving responses, doing assignments, concluding, and presenting. Class X students at SMA Islam Samarinda have low active participation in learning activities. Therefore, the use of appropriate learning models and media is very necessary to attract students' attention so that students are more actively involved in learning activities. This study aims to determine the effect of the Problem Based Learning (PBL) learning model assisted by pop-up book media on students' active participation in ecosystem material for class X at SMA Islam Samarinda. The type of research used is quantitative research with a quasi-experimental method and uses a research design, namely pretest-posttest control group design. The sample in this study was class X-1 as an experiment and class X-2 as a control, where each class consisted of 25 students, so that the total sample was 50 students, with a sampling technique of simple random sampling. Data collection in this study used a student active participation questionnaire, with data analysis using a hypothesis test using an independent sample t-test with a significance level of 5%. Based on the research conducted, a 2-tailed significance value of 0.000 < 0.05 was obtained, indicating that the Problem-Based Learning (PBL) model using pop-up books significantly influenced student active participation in ecosystems material for 10th grade students at SMA Islam Samarinda.

Abstract

This study aims to determine the influence of the STEM-SDGs approach on improving scientific skills and student learning outcomes on Excretory System material at SMA Islam Samarinda. This study uses a quasi experiment method with a non-equivalent control group design. The research sample was selected through a purposive sampling technique consisting of two groups, namely the experimental class of 26 students and the control class of 26 students. Data analysis was carried out using an independent sample t-test. The results of the study show that the STEM-SDGs approach has a significant effect on improving students' scientific skills, especially in the aspects of observing, reasoning, and communicating, as well as on learning outcomes shown through improving post-test scores. The engineering aspect is the most influential component, because it trains students to design and create projects based on the use of used goods according to the SDGs. Thus, it can be concluded that the STEM-SDGs approach is effective in improving students' scientific skills and learning outcomes through integrative and contextual project-based learning.

Abstract

The effect of light on stomata has been extensively studied, but studies that specifically observed the effect of light intensity on the size and number of stomata in monocot plants at the Sempaja Arboretum, Samarinda, are still very limited, including monocot plants, and have the potential to be a contextual learning resource for biology education in schools. The purpose of this study is to determine the effect of light intensity on the number and size of stomata in monocot plants in the Sempaja Arboretum. This research was carried out from February to May. This study used a Non-Factorial Group Random Design, with 3 different light intensities (morning, noon, and evening). Based on the results of statistical tests (ANOVA and Duncan's follow-up tests), not all species show statistically significant differences in size and number between times (morning, noon, evening). Some species such as Sri Rejeki (Aglonema sp) and Turmeric (Curcuma longa) show statistically insignificant changes. In other species such as Virginia Flower (Commelina virginica), Palm (Arenga pinnata), and Golden Ivory Betel (Epipremnum aureum), the difference in stomata size between times is more pronounced and significant.

Abstract

This study aims to determine the microplastic content in several types of shellfish in Tanjung Batu waters, Berau Regency. The type of research used is qualitative research, with descriptive analysis methods. The samples used in this study were blood clams (Anadara granosa) and cockles (Polymesoda erosa) taken from the sea waters of Tanjung Batu, Berau Regency, East Kalimantan. Observations were made at the Biology Education Laboratory, Teaching and Education Faculty, Mulawarman University. The results showed that blood clams (Anadara granosa) and cockles (Polymesoda erosa) contained microplastics. The types of microplastics found included fibers, fragments, and films. The type of microplastic that is found the most is fiber and the least is film.
