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

Critical thinking skills are a key component required in completing independent tasks (Sukenda, 2016). This study aims to analyze correlation between students' critical thinking skills and the quality of independent assignments in Histology courses. The research method used was a correlational quantitative approach involving 35 Biology Education study program students who were taking Histology courses. Data were collected through a histology context-based critical thinking test and independent assignment assessment using an analysis rubric. The correlation test results showed a positive correlation between critical thinking skills and the quality of students' independent assignments (r = 0.244, p < 0.05). This finding indicates that although there is a positive correlation coefficient between critical thinking ability and independent assignment quality, the significance value (Sig.) of 0.157 indicates that the correlation is not statistically significant. Based on this data, it can be concluded that there is no significant correlation between students' critical thinking skills and the quality of their independent assignments in the Histology course.

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

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian pupuk kompos tandan kosong kelapa sawit (Elaeis guineensis J.) dan kotoran burung walet (Collocalia vestita) terhadap pertumbuhan dan hasil tanaman cabai rawit (Capsicum frutescens L.). Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 16 kombinasi perlakuan dan 3 ulangan. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, jumlah buah, dan berat basah buah. Hasil penelitian menunjukkan bahwa kombinasi perlakuan pupuk kompos tandan kosong kelapa sawit 75 gram dan kotoran burung walet 20 gram memberikan hasil terbaik pada semua parameter. Hal ini menunjukkan bahwa kombinasi kedua jenis pupuk organik tersebut mampu meningkatkan pertumbuhan tanaman dan hasil panen secara signifikan. Kandungan unsur hara yang dibutuhkan tanaman dalam jumlah besar maupun kecil, seperti nitrogen (N), fosfor (P), kalium (K), dan C-organik, berperan dalam mendukung proses penting dalam tubuh tanaman seperti pembuatan makanan (fotosintesis), pembentukan sel baru, serta perkembangan dan pengisian buah. Dengan demikian, penelitian ini memberikan alternatif pemupukan yang ramah lingkungan, memanfaatkan limbah pertanian dan peternakan, serta mendukung pertanian berkelanjutan dan ketahanan pangan.
