Abstract

This study aims to describe the effectiveness of the Problem-Based Learning model assisted by Canva oriented to Pancasila Student Profiles and to analyze the effect of its implementation on scientific literacy skills in static electricity material. This research was conducted at SMP Negeri 1 Kwandang with 31 students in class IXA as subjects. This development research uses Research and Development (R & D) research with the ADDIE development model developed by Reiser and Mollenda, which consists of the Analysis, Design, Development, Implementation, and Evaluation stages. The effectiveness test is carried out at the implementation stage. The results showed that the effectiveness of learning devices was seen through student activity data obtained by an average percentage of 93.27% obtained by very good criteria, and students' scientific literacy tests showed an increase in the N-gain score with an average N-gain score of 0.72 with high classification. This research concludes that physics learning tools that use the Problem-Based Learning model assisted by Canva-orientated Pancasila Student Profiles on static electricity effectively increase students' scientific literacy skills.

One learning model that supports improving critical thinking skills and developing 21st century education is the PBL model. This research aims to describe the quality of the STEAM approach-based PBL model learning tools development for Students' Critical Thinking Ability on the concept of sound wave using the ADDIE development model. The results of the validation carried out by three validators obtained an average percentage for the learning implementation plan of 93.08%, student activity sheets of 92.58%, teaching materials of 90.82%, and critical thinking tests of 92.72%, and all included in the very valid criteria. The practicality of learning tools is seen from learning implementation of 90.72% with excellent criteria, the student's response to the learning tools was very positive with the ease aspect percentage of students' responses was 86.67%, the enthusiasm aspect percentage of 93.33%, the motivated aspect percentage of 86.67% and the involvement aspect percentage of 83.33%. The effectiveness of learning tools in student activity of 91.67% with excellent criteria, the results of the critical thinking test increased by 49.00%, from previously the overall average score of students was 30.33% to 79.33% and the effectiveness category through the N-Gain test was 0.71 with high criteria

Abstract

This research aims to determine the influence of the Problem-Based Learning (PBL) model to student learning outcomes on heat and transfer concepts by using experimental research, with the research design being One Group Pretest-Posttest Design. The population of this study was class VII students of SMP Negeri 5 Gorontalo. The sample consists of 3 classes, namely experimental class, replication 1, and replication 2, with the sampling technique being Cluster Random Sampling. The instrument of research used was a learning outcomes test in the form of a pretest-posttest to see student learning outcomes. Then, the data was analyzed using descriptive and inferential statistics, including normality tests, hypothesis tests, and n-gain analysis. The average score for class VII students is greater than the Criteria for Achieving Learning Goals, shown by an average score for the experimental class of 82.25, replication 1 of 79.94, and replication 2 of 79.04, compared to the Criteria for Achieving Learning Goals of 70. Based on the hypothesis testing criteria for the class, experimental Tcount 7.036 is greater than Ttable 2.035, replication 1 Tcount 6.684 is greater than Ttable 2.035, and replication 2 Tcount 5.824 is greater than Ttable 2.035 so it stated Tcount is more prominent than Ttable. This can be interpreted that the PBL model influences student learning outcomes.

Abstract

Problem-based learning (PBL) is a learning model that focuses on problems and solving. This research aims to describe the influence of the PBL model on student learning outcomes on the concepts of measurement. This method is experimental and replication class. The research is carried out in class VII on Madrasah Tsanawiyah school at MTs Ma'arif Tolangohula for the 2023/2024 academic year. The research design used is one group pretest-posttest. Test the research hypothesis using the t-test where, before carrying out the t-test, the data is tested first using the requirements test, namely the normality test and the N-gain test. Based on the research results, it is known that learning using the PBL model in the experimental class obtained a post-test score of 85.18, replication 1 of 80.71, and replication 2 of 80.24, for the t-test in the post-test the experimental class obtained Tcount of 5.174 and Ttable of 2.131, for the replication 1 obtained Tcount of 3.133 and Ttable of 2.131, and replication 2 obtained Tcount of 4.287 and Ttable of 2.131. This shows that the PBL model has the influence of improving student learning outcomes on the concept of measurement.

Abstract

Research on the use of water hyacinth (WH) to improve the quality of polluted water has been widely reported, but discussions on the ability of WH to clear turbid water are still rare. This research examines the possibility of using WH as a natural clarifier for Lake Bata. Treatments with 3 variations in the percentage of lake closure with WH cultivation (25, 50, and 75%) were applied for 40 days with 3 repetitions. Water quality and turbidity measurements were carried out every 4 days. The data was analyzed descriptively in graphical form to see a model of these changes. It was found that the pollutants Fe, Hg, nitrate, phosphate and ammonia were present in very small and safe quantities, but the water turbidity level did not meet the standards of the Indonesian Minister of Health yet. During the WH growth, the turbidity decreasing follows the equation Y(25) = - 0.114x + 28.52; Y(50) = -0.195x + 29.83; and Y(75) = -0.235x + 30.14 for cover percentages of 25, 50 and 75% respectively, where y for the turbidity (NTU) and x for WH growth time (days). To meet turbidity standards, WH coverage percentages of 25, 50, and 75%, require cultivation periods of 32, 28, and 24 days, respectively.

Abstract

Teaching modules are independent curriculum bodies which replace learning plans. This study aims to development of teaching module based on independent learning to optimize students’ conceptual knowledge on the motion topic. The development of teaching modules using the ADDIE model consists of five stages: analysis, design, development, and implementation. This research used 15 class VII students as teachers at SMP Negeri 3 Satap Tabongo. Based on the validation results from three validators, the average percentage for the teaching module was 81.25%, which was in the very valid category and suitable for use in learning the motion topic. Based on the practicality of the Independent Curriculum-Based Teaching Module to optimize students' conceptual knowledge, it meets the practicality criteria with a score of 93.18% for teachers and student activities of 91.67%.and the results of the student responses were very good. Based on the effectiveness of the Independent Curriculum Based Teaching Module to optimize students' conceptual knowledge, it meets the criteria for effectiveness.
