Abstract

The purpose of this study was to examine the effectiveness of the STEM (science, technology, engineering, and mathematics)-based Project-Based Learning (PjBL) model in improving senior high school students’ scientific literacy. This study employed a quasi-experimental method with a pre-test and post-test nonequivalent control group design and was conducted at SMA Negeri 5 Padangsidimpuan. The research involved two classes consisting of 35 students each: an experimental class taught using STEM-based PjBL and a control class taught using conventional learning. Scientific literacy was measured using an essay test, while students’ attitudes toward science were assessed through a questionnaire. The results of the independent samples t-test showed no significant difference in students’ initial abilities (sig. = 0.064 > 0.05). However, the post-test results indicated a significant difference between the two groups (sig. = 0.000 < 0.05), with the experimental class achieving a higher mean score. In addition, students’ attitudes toward science in the experimental class were categorized as good to very good. These findings indicate that STEM-based Project-Based Learning is effective in enhancing students’ scientific literacy.

Abstract

This study aims to analyze the effect of the peer tutoring method on learning activity, learning motivation, and biology learning outcomes of grade XI students at SMAN 15 Gowa. This quasi-experimental research employed a pretest-posttest control group design involving 54 students divided into experimental (n = 27) and control groups (n = 27). Learning activity was measured using observation sheets based on Paul B. Diedrich indicators, motivation was assessed through questionnaires using Keller's ARCS model, and learning outcomes were evaluated using cognitive tests consisting of 25 multiple-choice and 5 essay questions based on revised Bloom's taxonomy. Data were analyzed using Independent Samples t-test to compare groups and Paired Samples t-test to analyze improvements within groups, with a significance level of α = 0.05. The results showed significant effects of peer tutoring on learning activity (p = 0.015), motivation (p = 0.000), and learning outcomes (p = 0.000). The experimental group demonstrated higher mean scores in activity (25.93 vs 24.44) and substantial improvements in motivation (N-Gain 0.61, medium category vs 0.12, low category) and learning outcomes (N-Gain 0.57, medium category vs 0.29, low category). The mastery level achievement in the experimental group (92.60%) was substantially higher compared to the control group (66.70%). Superior performance can be attributed to enhanced peer interaction facilitating deeper conceptual understanding through social constructivism and the Zone of Proximal Development. These findings indicate that the peer tutoring method effectively enhances students' learning activity, motivation, and outcomes in complex biology topics, with practical implications for improving biology education quality at the secondary school level.

Abstract

This research is motivated by the fact that low learning activities also affect student learning outcomes in science learning in elementary schools. Students are less active in the learning process, both in expressing opinions, asking questions, and constructing their own knowledge. Students tend to wait for direction from the teacher, and only a few are actively involved in group discussions. One effort that can be done is to use the CTL learning model. This study aims to determine the effect of the CTL learning model on learning activities and student learning outcomes in the ecosystem material in cluster II Sungai Penuh.The type of research used Is Quasi Experimental. The research population was students of Elementary School Cluster II Sungai Penuh. The sample of this research was students of class Va SDN 025/XI Gedang Village Sungai Penuh as the experimental class and students of class Vb SDN 001/XI Sungai Penuh as the control class. The instruments used in this research were learning activity questionnaires and learning outcome test sheets. The data analysis technique used prerequisite tests in the form of normality and homogeneity tests. Meanwhile, to test the hypothesis using an independent t test. To determine the relationship between learning activities and learning outcomes, a correlation test was carried out. The results of this study indicate that there is an influence of the CTL learning model on learning activities and student learning outcomes on ecosystem material in cluster II of the full river. The details of the data analysis results are: (1) The CTL learning model improves student learning outcomes by linking lesson materials to everyday life so that concepts are easier to understand, as evidenced by the results of the study which obtained a significance value of 0.000 for the posttest. By taking a significance value of 5%, it is concluded that H0 of this study is rejected, while H1 is accepted, meaning that there is an influence of the CTL learning model on student learning activities. (2) The CTL learning model improves student learning activities, as seen from active involvement in discussions and completing assignments, as evidenced by the results of the study which obtained a significance value of 0.000 for the posttest. By taking a significance value of 5%, it is concluded that H0 of this study is rejected, while H1 is accepted, meaning that there is an influence of the CTL learning model on student learning outcomes. (3) There is an influence of learning activities on student learning outcomes by using the CTL learning model.

Abstract

Using a quantitative correlational design, this predictive research was based on secondary EDOM data. The first episode of the school year 2024/2025 served as the data collection period. The target population of this research are the lecturer subjected to students’ evaluations from Universitas Al-Irsyad Cilacap. After processing the data and cleaning and aggregating, a total of 594 records of the lecturer were analyzed with a census technique. K-Means was used to detect the presence of latent patterns of performance in the teaching, professional, personality and social dimensions of the lecturer. The Random Forest model was used to predict the performance category of the lecturer from both the baseline and hybrid models. The results of the study showed that the hybrid models were able to predict with a high measure of accuracy, and of the two, the hybrid model was the most robust when compared to the baseline model with a manual high-defined grouping of performance levels. The baseline model was able to completely and perfectly classify the group, the hybrid model with high performance was able to analyze the data in a general way, revealing a structure of performance that was hidden in the data. This means that, there is greater analytical value to the data. This analysis of EDOM data is of high analytical value. The developing of the hybrid model of lecturer performance analysis provides a positive contribution in data-driven quality assurance and decision-making to higher education. Objectives were met.

Abstract

Damage to vital organs such as the liver, kidneys, and pancreas is a common complication of diabetes mellitus, characterized by chronic hyperglycemia due to pancreatic cell dysfunction. Graptophyllum pictum (purple leaf) is a potential herbal therapy containing bioactive compounds with antioxidant and organ-protective effects. This study aimed to evaluate the effect of purple leaf emulsion on blood glucose levels and the histopathological features of diabetic rats induced by streptozotocin. Rats were divided into six groups: normal control, negative control, positive control (glibenclamide), and three doses of purple leaf emulsion (100, 200, and 300 mg/kg BW). After 28 days of treatment, the emulsion significantly reduced blood glucose levels and improved the histological structures of the liver, kidneys, and pancreas. The 200 mg/kg BW dose was most effective for pancreatic protection, while 300 mg/kg BW provided optimal hepatoprotective and renoprotective effects. These findings highlight the potential of purple leaf as a natural antidiabetic and organ-protective agent.

Abstract

Land conversion due to the increasing population growth rate for various interests has impacted forest land, and deforestation has become a global problem. One step that can be taken in regional planning to utilize and manage forest resources based on the landscape is to develop an agroforestry system. Agroforestry is a method of land management that combines (mixed use) forest plants with agricultural crops or livestock farming within a single area. One area that utilizes land through an agroforestry system is Sipolha Horisan Village, Pamatang Sidamanik District, Simalungun Regency. The purpose of this study was to determine the plant species’ composition and agroforestry landscape pattern in Sipolha Horisan Village. The results showed that the agroforestry system practiced by farmers was agrisilvicultural agroforestry, with a random pattern. Carbon storage potential is influenced by plant growth rates. At the tree level, the biomass was 313.18 tons/ha and carbon stocks were 144.06 tons/ha. For understory plants, the biomass was 19.89 tons/ha and carbon stocks were 9.15 tons/ha. The litter produced 39.77 tons/ha of biomass and carbon stocks were 18.29 tons/ha.

Abstract

Brain tumors are diseases that require early detection and accurate diagnosis. Various studies have applied deep learning methods to classify MRI images of brain tumors, but they still face dataset limitations and imbalanced class distributions that impact model performance. This study aims to evaluate the performance of the transfer learning-based VGG16 model in classifying brain tumors using MRI images. The study used 7,023 MRI images, including glioma, meningioma, pituitary, and no tumor, with a balanced training data distribution. Pre-processing included resizing, data splitting, and augmentation in the form of rotation, width shift, height shift, and zoom to increase data diversity and reduce the impact of class imbalance. The model was trained using several training-validation data splits (70:30, 80:20, and 90:10) with variations of the Adam, RMSprop, and AdamW optimizers and learning rates between 0.1 and 0.0001. The best configuration was obtained in the 80:20 scenario with the Adam optimizer and a learning rate of 0.0001, which was used in the final testing stage using test data that were never used during training and validation. The results showed the highest validation accuracy of 99.89% and a testing accuracy of 98.00%. Confusion matrix analysis showed that all classes could be classified well without prediction bias.
