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

The average biology learning outcomes of eleventh-grade students at MA Negeri 1 Samarinda are still below the Minimum Completion Criteria (KKM), while innovative learning models such as POE (Predict-Observe-Explain) have never been implemented. Biology learning has been mostly based on lectures, discussions, assignments, and practicums, while scientific attitude assessments are only taken from daily life and practicum activities. This condition requires the implementation of a model that can actively involve students to encourage scientific attitudes and science process skills (SPS). This study aims to determine the effect of the POE model on the scientific attitudes and SPS of eleventh-grade students on the sensory system material. The method used is a quasi-experimental design with a Nonequivalent Control Group Design, involving class XI-F as the experiment and XI-D as the control. The research instruments are scientific attitude questionnaires and SPS tests. The results of the analysis show significant differences between the experimental and control classes in scientific attitudes (p < 0.05) and SPS (p < 0.05 with the Mann Whitney U test). Improvements in scientific attitudes were demonstrated by an N-gain of 0.35 (moderate) in the experimental class and 0.19 (low) in the control class. Meanwhile, the N-gain of the Student-Based Learning (KPS) reached 0.60 (moderate) in the experimental class and 0.29 (low) in the control class. The conclusion of this study is that the POE model effectively improves the scientific attitudes and science process skills of eleventh-grade students at MA Negeri 1 Samarinda.

Abstract

Green lettuce (Lactuca sativa) is a horticultural crop that is becoming increasingly popular due to its high nutritional content. This plant plays an important role in improving the nutritional intake of the community. This study aimed to determine the effect of using eco-enzyme on the growth of green lettuce plants and to identify the best concentration. The research was conducted from June to August 2025 on a limited area using the wick hydroponic system located on Jalan Abdul Wahab Syahrani, Gang Wangi, Gunung Kelua, Air Hitam, Samarinda City, East Kalimantan Province. This study used a Randomized Block Design (RBD) consisting of five treatments, each repeated five times, namely: P0 (control/1 L), P+ (control plus/AB mix 10 ml/L), P1 (EE 10 ml/L), P2 (EE 15 ml/L), and P3 (EE 20 ml/L). Data on plant height and number of leaves were analyzed using Two-way Multivariate Analysis of Variance (Two-way MANOVA) followed by the Bonferroni test at a 5% significance level. Meanwhile, the data on fresh weight were analyzed using One-way Analysis of Variance (One-way ANOVA). The results showed that eco-enzyme treatment had a significant effect on plant height, number of leaves, and fresh weight of green lettuce, with the best concentration obtained from treatment P1 (EE 10 ml/L).

Abstract

Pest infestations are one of the limiting factors in the cultivation of pull-up spinach, which can reduce crop quality and productivity. Pest control methods that still rely heavily on chemical pesticides have the potential to disrupt the environmental balance. The development of botanical pesticides is an approach that continues to be studied as a more ecological method of pest control. The stems of brotowali and the leaves of belimbing wuluh are known to contain bioactive compounds that have the potential to be utilized as botanical pesticide ingredients. This study aims to determine the effect of a combination of extracts from brotowali stems (Tinospora crispa L.) and belimbing wuluh leaves (Averrhoa bilimbi L.) on the intensity of pest insect attacks on Maestro variety spinach (Amaranthus tricolor L.) plants, as well as to determine the optimal concentration of the combination. This study is an experimental study using a non-factorial Randomized Block Design (RBD) with five treatment levels, namely 0% (control), 15%, 30%, 45%, and 60%, with five replicates. The observed parameter was the intensity of insect pest attacks based on the level of leaf damage at 14, 19, 24, 29, dan 34 day after sowing. The data were analyzed using analysis of variance (ANOVA) and followed by the Least Significant Difference (LSD) test at a 1% significance level. The results of the study showed that the calculated F-value at all observation time was greather than the critical F-value at the 1% level, thus the combination of brotowali stem extract and belimbing wuluh leaf extract had a highly significant effect on the intensity of pest insect attacks on Maestro variety spinach. The 60% concentration proved be the most effective in suppressing the intensity of pest insect attacks.

Abstract

This study aims to analyze the relationship between reproductive health knowledge and attitudes toward the prevention of sexually transmitted diseases among students. This study employs a quantitative approach using a correlational method. Data collection was conducted by distributing questionnaires to students as research respondents. The obtained data were analyzed using normality tests and correlation product moment tests. The results indicate that the data are normally distributed. Based on the results of correlation product moment test, a correlation coefficient of 0.449 was obtained, which falls into the moderate category, indicating a positive relationship of moderate strength between reproductive health knowledge and attitudes toward the prevention of sexually transmitted diseases among students. This positive relationship suggests that the higher the level of reproductive health knowledge students possess, the better their attitudes toward preventing sexually transmitted diseases. The moderate strength of the association indicates that knowledge of reproductive health is not the only factor influencing attitudes toward the prevention of sexually transmitted infections.
