Abstract

An initial survey showed that some chemistry teachers at the MGMP of Mojokerto Regency and City had never attended argumentation skills training. Argumentation skills are important to practice as an effort to improve critical thinking skills, improve understanding and problem solving. This activity aims to improve the understanding and skills of chemistry teachers in Mojokerto in developing argumentation-based evaluation questions. This activity was carried out in two sessions through six stages of activities starting from preparation, training, monitoring, implementation, evaluation, and appreciation stages. The results showed that the development of teachers' understanding related to argumentation skills was analyzed using the N-Gain score and the majority were in the moderate group. The results of the question development also showed an increase in the level of argumentation skills. The response questionnaire showed that all teachers supported this PKM activity and the activity had been 100% implemented. This activity is expected to be one of the triggers for teachers to make their students more critical, creative and able to solve problems well through argumentation skills training.

Abstract

Educational developments in the 21st century require students to be prepared to face global competition. This preparedness can be supported by several basic skills that are equipped to each student as the future generation of the nation, for example, science literacy. Specifically, the study aims to produce and test the validity of a phenomenon-based advance organizer learning tool consisting of a teaching module, student worksheet, textbook, and science literacy assessment instrument. The method used is RnD, with the research design chosen being Thiagarajan's 4D model, which consists of define, design, develop, and disseminate. Data were obtained from three expert validators through validation sheets and analyzed using Aiken’s V formula to determine the validity level of each component of the developed learning tools. The expected outcomes include teaching modules, student worksheets, textbooks, and science literacy questions to be applied in chemistry education. Research data was obtained from three validators using a validation sheet. The validators consisted of two lecturers from the Faculty of Mathematics and Natural Sciences at Unesa and one chemistry teacher from Puri 1 Senior High School in Mojokerto Regency. The data was analyzed based on the validity criteria of each element of the learning tools using Aiken's validation. Previously, the learning tools were reviewed by two chemistry lecturers from the Faculty of Mathematics and Natural Sciences at Unesa with the assistance of a review sheet to obtain suggestions and input. The validity data showed that the learning tools were valid, with validity data meeting the validity criteria, where the teaching module scored 0.86 on the Aiken scale, the student worksheet scored 0.86 on the Aiken scale, the textbook scored 0.89, and the science literacy questions scored 0.99. These findings indicate that the developed learning tools meet high validity criteria and are suitable for use in chemistry learning. The integration of the phenomenon-based approach with the advance organizer model provides a structured framework that helps students connect abstract chemistry concepts with real-world phenomena, thereby improving science literacy and engagement. In conclusion, the phenomenon-based advance organizer chemistry learning tool developed in this study is valid and feasible to be implemented in high school classrooms to train students’ science literacy skills, and further research is recommended to test its effectiveness in improving learning outcomes.

Abstract

Objective: This study investigates the influence of pyrolysis and distillation processes on the chemical composition and antibacterial potential of liquid smoke produced from teak (Tectona grandis) sawdust waste, aiming to identify bioactive compounds relevant for natural antiseptic applications. Method: Teak sawdust was subjected to oxygen-limited pyrolysis at temperatures of 250–400 °C to produce crude liquid smoke, which was subsequently purified through distillation. Both pyrolysis and distillation fractions were analyzed using Gas Chromatography–Mass Spectrometry (GC–MS) to characterize and compare their chemical compositions, focusing on organic acids, phenolic compounds, furans, carbonyls, and polycyclic aromatic hydrocarbons (PAHs).  Results: GC–MS results demonstrated clear differences between the two processing methods. The pyrolysis fraction exhibited a higher proportion of organic acids (approximately 35%), contributing to lower pH and stronger antibacterial potential through synergistic effects of acids, aldehydes, furans, and phenolics. In contrast, the distillation process increased the relative phenolic content to around 40%, enriching stable compounds such as guaiacol, cresol, and syringol, while reducing highly volatile components. Both fractions contained low levels of PAHs, indicating that the processing conditions were adequately controlled and environmentally safe.  Novelty: This study offers a comprehensive comparison of pyrolysis and distillation pathways in converting teak sawdust into liquid smoke, explicitly linking processing techniques to changes in chemical composition and antibacterial functionality. By integrating detailed GC–MS characterization with functional interpretation, this work advances current knowledge on biomass valorization and provides a scientific basis for tailoring liquid smoke as a natural and sustainable antiseptic.

Abstract

To support the Independent Curriculum and meet 21st century learning expectations, it is critical to design an assessment system that can measure high-level thinking skills. One of the main challenges is the limited availability of formative assessments based on the Minimum Competency Assessment (AKM) that specifically evaluate critical thinking skills in thermochemistry. The goal of this project is to create a formative assessment tool based on the AKM framework that has strong validity and reliability for assessing the thermochemistry-related critical thinking abilities of eleventh-grade high school students. The ADDIE model served as the guiding framework for the development process. Three professional validators assessed the instrument's theoretical validity, while a sample of 34 eleventh-grade students from SMA Hang Tuah 1 Surabaya participated in empirical testing. The findings reveal that the instrument attained an exceptionally high level of theoretical validity, evidenced by content validity of 93.3%, construct validity of 100%, and language validity of 100%. A Cronbach's Alpha coefficient of 0.950 demonstrated the exceptional reliability and empirical validity of all 20 items. The majority of the items on the test were classified as moderately difficult and had a high capacity for discrimination, demonstrating the instrument's good qualitative qualities.
