Abstract

Education plays an important role in improving the quality of human resources. In the context of implementing the Merdeka Curriculum, teachers are given the freedom to design adaptive and contextual learning processes. Based on preliminary research findings, 50% of students reported difficulties in understanding chemical equilibrium material, with the main obstacles being unfamiliar terminology, excessive memorization, and complex calculations. To address these issues, this study aims to develop guided inquiry-based Learner Activity Sheets on chemical equilibrium material to improve the learning outcomes of class XI high school students. Chemistry learning, especially on the topic of chemical equilibrium, sub-material factors that affect the direction of chemical equilibrium shifts, is often considered abstract and difficult for students to understand, so learning media is needed that can facilitate critical thinking processes and conceptual understanding. Guided inquiry was chosen as a learning approach because it provides a balance between teacher direction and independent exploration by students. The research method used is Research and Development (R&D) with reference to the 4-D development model (Define, Design, Develop, and Disseminate) and limited to the Develop stage only. The population in this study was class XI of IPIEMS Surabaya High School. The results of Learner Activity Sheets validation from the three validators obtained a mode score of 5, which means that Learner Activity Sheets is feasible with very valid categories. The percentage of students' responses obtained was 96% which was declared practical. The learning outcomes of students are declared complete if they reach a score of ≥ 80. Based on the posttest results, the percentage of completeness is 88.5%. This percentage shows that classical completeness has been achieved, so it can be concluded that guided inquiry-based learning is effective in improving student learning outcomes.

Abstract

Education plays a crucial role in supporting the achievement of the SDGs, especially through the integration of ESD principles in the learning process. This study aims to analyze the implementation of ESD values in environmental aspects at Kalirejo 1 Junior High School, which is a provincial Adiwiyata school. This research uses a qualitative approach, collecting data through interviews, observations, questionnaires, and documentation. Data analysis techniques used in this research are data reduction, data presentation, and conclusion drawing. Informants in this study included the principal, vice principal for curriculum, science teachers who were also Adiwiyata team leaders, and student representatives from nine extracurricular activities (two students per extracurricular activity). This study evaluated 99 ESD indicators in the environmental aspect, and the results showed that 94 indicators (95%) had been successfully implemented, which include natural resources, climate change, rural development, sustainable urbanization, and disaster prevention and mitigation. These practices have been integrated into the Merdeka Curriculum, both through learning activities and school culture that builds environmental awareness. However, there are still some challenges, namely the non-optimal drainage system and water conservation facilities, such as biopores. This shows that Kalirejo 1 Junior High School has a strong commitment to implementing sustainable education. However, there is still room for improvement so that the implementation of ESD at 1 Kalirejo Junior High School can run more thoroughly, effectively, and sustainably in the future.

Abstract

Critical thinking skills are essential abilities that students must have to face the challenges of learning in the 21st century. However, the PISA test results in 2022 showed that the critical thinking skills of Indonesian students were still low compared to the average OECD country. This research aims to produce electronic student worksheets based on project-based learning (PjBL) to improve students' critical thinking skills on green chemistry materials. This type of research is development research with a one-group pretest-posttest design and uses the 4D model from Thiagarajan, Semmel, and Semmel’s (1974). This 4D development model consists of four stages: define, design, develop, and disseminate, but is limited to the development stage only. This research was conducted at SMAN 7 Surabaya, with the research subjects being class X-6 students, a total of 28 people. The feasibility of this learning media was reviewed from its effectiveness. The effectiveness was measured through cognitive tests with scores above the learning objective completeness criteria ≥ 75%, which showed a percentage of 100% classical completeness. Effectiveness is also seen from the results of the critical thinking ability test. Critical thinking ability test data was tested with the Shapiro-Wilk normality test and obtained a significance of < 0.05, so further tests were carried out using the Wilcoxon Signed Rank test and obtained a significance of 0.000, which stated that there was a difference between pretest and posttest data. Thus, the learning media developed can be declared effective based on the results of cognitive test data and critical thinking ability test data. Unlike previous studies that focused on creative thinking skills, this study uniquely targets critical thinking skills using PjBL.

Abstract

Problem-solving ability is one of the abilities that support the achievement of the Profil Pelajar Pancasila. In reality, problem-solving skills are still low and need to be improved. Based on the literature study, student worksheet learning tools using the inquiry model can train problem-solving skills. The research objective is expected to produce an effective student worksheet to improve problem-solving skills on the material of factors that affect the reaction rate. The student worksheet was developed following the ADDIE (Analyze, Design, Develop, Implement, Evaluate) stages, up to the develop and pilot implementation stage. The pilot implementation target was 28 students of class XI-3 SMA Negeri 7 Surabaya. Student worksheets in this study were developed referring to the indicators of problem-solving ability, namely recognising the problem, describing the problem, planning a solution, executing the plan, and evaluating the solution. The effectiveness of the student worksheets was determined based on the results of the problem-solving ability test. The effectiveness test design used was a one-group pretest-posttest Design. Pretest and posttest data were analyzed using a normality test and a paired t-test. The student worksheet developed was declared effective if there was an increase in students' problem-solving ability test scores between before and after the trial.  The problem-solving ability test results were tested with the Shapiro-Wilk test. The prerequisite test results showed normal distribution because the p-value> 0.05. Followed by hypothesis testing using a paired t-test (one-tail).  Data analysis using a paired t-test (one-tailed) resulted in a p-value of 0.000 <0.005, so there was a significant increase in the problem-solving score. Thus, student worksheets developed using the inquiry model are declared effective for improving students' problem-solving skills in the material of factors that affect the reaction rate.

Abstract

Learning outcomes are very important as a benchmark for success in the learning process. This study aims to determine the effect of the Problem-Based Learning (PBL) model on improving student learning outcomes in the material of classification of living things at SMP Negeri 1 Suwawa. The method used is Quasi-experimental with a pretest-posttest control group design. The sample consisted of two classes, namely class VII A as the experimental class and class VII C as the control class, which were selected by random sampling. The instrument used was a multiple-choice test of 15 questions. The pretest results showed an average learning outcome of students in the experimental class of 49.8 and the control class of 50.2. After learning, the posttest results increased to 84.3 for the experimental class and 72.1 for the control class. The N-gain value of the experimental class was in the medium-high category with an average of 0.68, while the control class was in the medium category with an average of 0.44. The t-test results showed t-table, namely 5.62 ˃ 2.00 (at a significance level of 0.05), which means that there is a significant difference between the learning outcomes of students using the PBL model and those using the Discovery Learning model. Thus, it can be concluded that the PBL model-based learning has a positive and significant influence on student learning outcomes in the material on the classification of living things.

Abstract

Fermentation is a biotechnological process that can modify chemical characteristics and increase antioxidant activity. The effect of fermentation time is very important for the quality of Andrographis paniculata (Andrographis paniculata) kombucha. This study aims to investigate the potential of sambiloto leaves (Andrographis paniculata) as a base ingredient in kombucha production and to analyze the effect of varying fermentation durations (0, 3, 6, 9, and 12 days) on the chemical characteristics and antioxidant activity of the resulting kombucha. The parameters evaluated include pH, total titratable acidity, total reducing sugars, total flavonoid content, and antioxidant activity. The results showed that the pH of kombucha decreased with increasing fermentation time, from 3,92 ± 0,02 on day 0 to 3.08 ± 0.01 on day 12, indicating enhanced activity of acetic acid-producing microorganisms during fermentation. Titratable acidity increased from 0.11 ± 0.01% to 0.93 ± 0.02%, reflecting the accumulation of organic acids. Total reducing sugar levels initially increased on day 3 (655.72 ± 0.68 mg/mL), then declined to 309.94 ± 0.83 mg/mL by day 12, possibly due to microbial consumption. The total flavonoid content showed a consistent increase from 0.008 mg/mL QE to 0.019 mg/mL QE, indicating the gradual release of bioactive compounds throughout the fermentation process. The highest antioxidant activity was recorded on day 9 (74 ± 0.47%), followed by a slight decrease on day 12 (72 ± 0.00%). These findings suggest that the inclusion of sambiloto leaves does not inhibit fermentation but rather enhances the production of beneficial bioactive compounds. Therefore, sambiloto holds strong potential as a functional ingredient in kombucha rich in natural antioxidants.
