Abstract

AbstractThis research was instigated by the teacher difficulty at school in implementing the appropriate learning method in online learning process. This research aimed at designing SSCS (Search, Solve, Create, and Share) based student electronic worksheet on Hydrocarbon lesson, and finding out validity and practicality SSCS based student electronic worksheet as a teaching material on Hydrocarbon lesson. This study uses the Borg and Gall development model, which only takes 5 out of 10 stages, namely data collection, planning, product development, initial trials and initial product revisions. Preliminary testing was conducted at State Senior High School 5 Tapung by a Chemistry subject teacher and 10 of the eleventh-grade students of MIA. The data obtained were analyzed by using quantitative descriptive analysis technique.   The data analysis result of validity test showed that the percentages were 97.14% by media experts with very valid category and 92.5% by material experts with very valid category. In practicality test by teachers, the percentage was 95.71% with very practical category, and the percentage of student response test was 54% with practical enough category. However, this research still has some shortcomings so it is expected that in the future an effectiveness test will be carried out to determine the effectiveness of the media. This research is expected to help the learning process.Keywords : Student Electronic Worksheet, SSCS, Hydrocarbon

Abstract

The pyrazole scaffold modification in various chemical structures on several studies has shown various biopharmacological activities. This study aims to predict the potential inhibition of pyrazole analogs derived benzene-sulfonylurea (4A, 4B, 4E, 5A, 5C, 5D) against the α-glucosidase (3A4A) and aldose reductase (3RX2) enzymes based on a molecular docking approach using Molecular Operating Environment (MOE) 2020.0102 software and evaluate pharmacokinetic profile (ADMET). In this study, the six test compounds were obtained from previous studies that have been proven antihyperglycemic. The results showed that all the 3,5-disubstituted benzene-sulfonylurea derivative pyrazole analogs are predicted to have low inhibitory activity against the α-glucosidase enzyme. Further, all compounds showed good aldose reductase inhibitor activity and had lower binding free energy values ​​than tolrestat as the positive control (-6.82 kcal/mol). Compound 5C has the best potential inhibitory activity against the aldose reductase enzyme compared to the other test compounds, because it has the lowest binding free energy value (-8.76 kcal/mol) and interacts with important residues on the receptor forming four hydrogen bonds, namely the carbonyl group of SO2 with residues Trp111 and His110, and the carbonyl group of the amide with residues His110 and Tyr48, as well as 3 hydrophobic bonds, namely a pyrazole ring with residues Leu300, Trp219 and a furan ring with Phe122. ADMET properties of the compounds are also predicted. This information provides an opportunity for a 5C compound as an aldose reductase inhibitor agent to develop drug candidates with better and safer activities.

Abstract

Abstract thinking skills are essential for understanding microscopic concepts in chemistry, particularly in topics such as chemical bonding. This study investigates the effectiveness of augmented reality (AR) as an innovative instructional medium that enhances students’ abstract thinking abilities within the context of chemical bonding. A mixed-method approach with a sequential explanatory design was employed, beginning with a quantitative phase followed by qualitative analysis. The participants were tenth-grade students at one of Madrasah Aliyah Negeri Pekanbaru, selected through purposive sampling. Data were collected using essay-based assessments, semi-structured interviews, and document analysis. The quantitative findings indicate a statistically significant improvement in the abstract thinking skills of students in the experimental group compared to the control group (p = 0.001), with 73.7% of students in the experimental group showing marked progress. Qualitative data further support these results, highlighting that AR facilitated students’ abilities in structural representation, abstraction, and metacognitive awareness. Additionally, AR increased student motivation and deeper engagement with the learning material. These findings suggest that integrating AR in chemistry instruction can be an effective pedagogical strategy to promote the development of abstract reasoning and 21st-century competencies.

Abstract

This study aims to describe the profile of students’ creative thinking skills following the implementation of the Project-Based Learning (PjBL) model on the topic of colloids. The research employed a descriptive method with a one-shot case study design. The participants were 33 eleventh-grade students from 11th Grade MIPA 4 at State Senior High School 1 Pekanbaru. Data were collected using validated essay test instruments and structured observation sheets. The results indicated that students’ creative thinking skills based on the essay test reached 56.18% (moderate category), while the observation results during the learning process reached 77.17% (good category). An analysis of the creative thinking indicators revealed that the fluency aspect achieved 71.21%, originality 52.62%, elaboration 48.47%, and flexibility 45.85%. A similar pattern was observed in the observation data, where fluency obtained the highest score, followed by originality and elaboration. However, the flexibility aspect remains in the lowest category compared to the other indicators, both in the essay test and observation results. These findings imply that although the PjBL model effectively stimulates idea fluency and originality, more targeted instructional interventions are needed to enhance students’ cognitive flexibility in solving complex chemistry problems

Abstract

Water treatment materials are often considered abstract and complex for students to understand. Relevant technologies, such as electrocoagulation (EC), have not been optimally integrated in learning. This study aims to develop and evaluate the feasibility of an electrocoagulation prototype-based learning medium designed to bridge these pedagogical gaps. Using the Research and Development (RD) method with an adaptation of the Borg and Gall model, feasibility data were collected through expert validation and practicality questionnaires, then analyzed using quantitative descriptive statistics. The results show that the media is Very Valid (average score of 91.53%) and Very Practical (89.23%). Furthermore, the prototype received a Very Interesting response from students (90.07%), indicating strong engagement potential. This medium successfully concretizes abstract concepts such as redox reactions and flocculant formation into tangible, real-time phenomena, effectively bridging the gap between conventional methods and modern industrial technology. It is concluded that this prototype is a valid and innovative tool for chemistry education, with significant potential for future integration with IoT-based sensors to enhance data-driven STEM learning further.
