Abstract

This research developed an environment-based critical thinking skills test instrument for science learning in class VII middle school to answer the problem of students' low critical thinking skills in Indonesia. The aim of the research is to produce a valid and reliable instrument to measure students' critical thinking skills in an environmental context. The research method uses the ADDIE development model with a pre-experimental design (one group pretest-posttest). Research findings show that the instrument developed has high validity and reliability and is able to significantly improve students' critical thinking skills. The conclusion of this research is that environment-based test instruments are effective in measuring and improving students' critical thinking skills. The implications of this research show the importance of integrating environmental issues in learning modules to improve the quality of science education in Indonesia.

Abstract

The development of learning in the 21st century emphasizes the improvement of Science Process Skills (SPS). However, the implementation of SPS has not been able to be realized by teachers due to the limitations of the teaching materials used. The data obtained shows that the average value of SPS for students is still categorized as low, which is 43.3%. This study aims to test the effectiveness of the implementation of E-module based on Problem Research Based Learning (PRBL) on students' Science Process Skills (SPS). The research method used is Quasi Experimental research with research samples of class VIII A and VIII D in one of the Surakarta State Junior High Schools. The experimental class was given an e-module based on PRBL containing material on elements, compounds and mixtures while the control class used the BSE book with an interactive lecture method. The data collection technique used a written test instrument in the form of a SPS test with a reasoned multiple choice type. The effectiveness test used was the t-test, effect size and n-gain score. The results of the t-test showed a significance value of 0.00 which means there is a significant difference between the experimental class and the control class. These results prove that there is a difference in the results of students' SPS between the experimental class and the control class. Furthermore, the results of the effect size test with a moderate effect category of 0.63 and the n-gain score test with a high category of 0.702 for the experimental class. Based on the results of the three tests, it can be concluded that the implementation of PRBL-based e-modules is effective in increasing students' SPS.

Abstract

High consumption of coal as a source of electrical energy in Indonesia has resulted in piles of waste from coal burning, namely fly ash, which can damage the environment and harm health. Fly ash contains main oxides, namely silica (SiO2) and alumina (Al2O3), whose components are similar to zeolite, so they can be synthesized into zeolite-like material (ZLM) which can be used as an adsorbent for heavy metal Ni2+. Therefore, this research discussed the characterization of manganese-oxide-coated-zeolite (MOCZ) from fly ash waste as a heavy metal adsorbent. The research procedure consisted of preparation, purification, and activation stage of fly ash to obtain fly ash that is free from impurities, the stage of making sodium silicate and sodium aluminate, and zeolite synthesis. The resulting zeolite was then coated with manganese oxide to expand the surface area of the zeolite and increase the ability of zeolite to adsorb heavy metal Ni2+. The research results showed that fly ash waste that was coated with manganese oxide can adsorb heavy metal Ni2+. The adsorption of the Ni2+ metal ion solution by zeolite with MOCZ modification is in line with the pseudo-second-order kinetic and Langmuir isotherm.

Abstract

This mixed-method research aimed to analyze the influence of the PjBL-STEAM learning model on the creative thinking skills of grade XI students through a jumputan batik pattern-making project. The main problem was the demand for creative adaptation skills in the 21st century. By collecting data through product assessment observations, questionnaires, and interviews, this study found that the PjBL-STEAM model had a positive and strong impact, particularly in the aspects of fluency and flexibility, which reached 75.50%–78.00%. However, significant challenges were found in the aspects of originality and elaboration, with lower scores (52.27%–58.20%), indicating the need for further development on the innovation and detail of students' work. Overall, the PjBL-STEAM model is effective, but it requires more specific guidance to encourage the generation of unique and detailed ideas.
