Abstract

This research aimed to analyze the feasibility of an e-module with the topic of synthesis of Metal Organic Frameworks (MOFs) Cu-BDC as adsorbents for Congo red and Metanil yellow dyes, as well as to analyze the improvement of students' scientific literacy after the implementation of a Problem Based Learning-based e-module in the material chemistry course using a Telegram bot application. The research method used was research and development with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Data collection techniques included observation, tests, and questionnaires. The research instruments consisted of test sheets and questionnaires that have been validated by experts. Data analysis technique used was quantitative analysis. Based on the validation results of the e-module by content experts, a score of 93.17% was obtained, media experts 95.8%, test validation results 88.75%, and student response questionnaire validation results 92.6%. Overall, it can be concluded that the validation results of the e-module fall under the category of very feasible. The student response questionnaire towards the e-module resulted in a score of 95% with a category of very feasible. The n-gain result obtained after the application of the e-module in the material chemistry course is 0.67 with moderate criteria. In conclusion, the e-module with the topic of synthesis of MOFs Cu-BDC as adsorbents for Congo red and Metanil yellow dyes using Problem Based Learning model and Telegram bot application is highly suitable for use as an alternative teaching material in the material chemistry learning process and can improve students' scientific literacy.

Abstract

This research was a quasi-experimental research with a one shot case study research design with the sample in this research being students of the Mathematics Education Study Program at HKBP Nommensen Pematangsiantar University, totaling 30 people obtained using the Simple Random Sampling technique, namely the PM A1 group. The purpose of this research is to find out how the Problem Based Learning model influences mathematical reasoning abilities. The research results showed that the average post-test result of students' mathematical reasoning ability = 64.77, meaning that mathematical reasoning ability is classified as good and the average result of observation of the Problem Based Learning model = 71.1, meaning that learning is implemented using Problem Based Learning using the Problem Based Learning model has been done well. Based on the value of students' mathematical reasoning abilities, the regression equation Y ̂ = 26.38 + 0.54X, b = 0.54, means that if the Problem Based Learning model increases by 1 unit, it will increase students' mathematical reasoning abilities by 0.54 units. To test the linearity of the regression, it was obtained that Fcount < Ftable or 0.009 < 3.65, meaning that there is a linear and meaningful relationship between the Problem Based Learning model and mathematical reasoning abilities. The results of the regression significance test obtained by the sample using the F test obtained Fcount > Ftable or 28 > 4.20 3.65, meaning that there is an influence between the Problem Based Learning model and mathematical reasoning abilities. From the results of Product Moment correlation calculations, rcount = 0.916, meaning that there is a very strong or very high relationship between the learning model and mathematical reasoning abilities. To test the significance of the correlation coefficient, tcount > ttable or 12.085 > 2.048, meaning there is a very strong and meaningful relationship between the Problem Based Learning model and mathematical reasoning abilities. And the results of calculating the coefficient of determination obtained r2 = 97.65%, meaning that mathematical reasoning ability is influenced by the Problem Based Learning model by 83.91% while the remaining 16.09% is influenced by other factors. From the results of the research above, it can be concluded that there is an influence of the Problem Based Learning model on reasoning abilities. So it is hoped that the Problem Based Learning model can be used as an alternative learning to improve mathematical reasoning abilities.

Abstract

[Implementation of Flood Mitigation E-Module to Improve The Junior High School Students' Environtment Literacy] This research’s purpose was to describe the differences of the students’ environment literacy before the students take part in learning using the flood disaster mitigation e-module and after they take part in learning using the flood disaster mitigation e-module. This research was conducted on 30 students of class VII at SMPN 2 Bengkulu using the one group pretest-posttest design method. The improvement of environment literacy is measured by giving the students a pretest-posttest. The pretest is carried out before learning using the flood disaster mitigation e-module to improve the students' environment literacy. Furthermore, after completing learning using the flood disaster mitigation e-module, the students were given a posttest. The students' environment literacy in this study covered three domains, namely knowledge, cognitive skills, and environmental care attitudes. The result of this research showed that there were differences in students' environment literacy before and after the students took part in learning with the flood disaster mitigation e-module, it can be seen from the overall environmental literacy N-Gain results of 0.6 in the medium criteria. Beside that, a significance value of 0.000 <0.05 was obtained, it was mean that there was a significant influence using the flood disaster mitigation e-module in increasing students' environmental literacy.

Abstract

This research aims to analyze the differences in critical thinking skills between students taught using the Problem Based Learning model and students taught using the Discovery Learning model. This research was type of quasi-experimental research, with a Pretest - Posttest Non Equivalent Control Group Design research design. The research sample was obtained from the entire population of class VIII students at SMP Negeri 1 Rendang, totaling 63 students using saturated sampling techniques. Data collection in this research was carried out using the test method. The data collection instrument used was a multiple choice test. The data obtained were analyzed using descriptive analysis techniques and t-test inferential statistical analysis. The results obtained in this research are as follows. (1) The t-test analysis shows the t value is 4,295 and the significance is less than 0.05 so the null hypothesis is rejected. This means that statistically there is a significant difference in critical thinking skills between students taught using the Problem Based Learning model and students taught using the Discovery Learning model. (2) Descriptively, the average critical thinking skills of experimental group I which used the Problem Based Learning model was 81, superior to experimental group II which used the Discovery Learning model with an average of 72. This shows that the evaluated comparison results of the Problem Based Learning model were superior to Discovery Learning model, especially on the Human Respiratory System material.

Abstract

Schools as one part of the educational unit have a fairly central role in facilitating learning activities through the use of technology. One use of technology in learning that is relevant in the current digital era is the use of e-learning. This research aims to develop a web-based e-learning system at SD Negeri 3 Sesetan. This research includes development research using the waterfall model which consists of the stages of needs analysis, system design, implementation, program testing and maintenance. Research subjects are participants involved as users and implementers in the field of e-learning. Data collection methods use questionnaires, observation methods, literature studies, and documentation. Next, the data was analyzed quantitatively, comparative analysis, deepening and sharpening were carried out in the form of limited discussions. The web-based e-learning system developed at SD Negeri 3 Sesetan provides a percentage of scores with good qualifications. Apart from that, the web-based e-learning design is in accordance with the curriculum and needs of teachers and students. Based on the results of this research, it can be concluded that web-based e-learning products are suitable for use as support for learning activities at SD Negeri 3 Sesetan.
