Abstract

Heavy metal pollution in aquatic systems increases the need for sustainable and efficient natural adsorbent materials, and carrageenan extracted from Eucheuma cottonii, which contains O–H, S=O, C–O–S, and 3,6-anhydrogalactose functional groups, offers strong potential for binding metal ions. However, the adsorption efficiency of natural carrageenan for Copper (Cu2+) and Cadmium (Cd2+) ions remains limited, which frames the central problem of this study. In addressing this issue, the method employed involves synthesizing carrageenan hydrogel through alkaline extraction of Eucheuma cottonii and evaluating its adsorption capacity under controlled experimental conditions. The hydrogel was characterized and tested at pH 6–7, with a contact time of 90 minutes, an initial concentration of 200 mg/L, and an adsorbent mass of 6 g, followed by kinetic and isotherm modeling to analyze adsorption behavior. Based on the Findings, ionic exchange interactions between sulfate ester groups of K-carrageenan and metal cations significantly enhance adsorption performance, with the adsorption process following a pseudo-second-order kinetic model and the Freundlich isotherm providing the best fit R2 > 0.90, indicating heterogeneous multilayer adsorption. In the Conclusion, the chemically modified carrageenan hydrogel demonstrates effective adsorption of copper and cadmium ions and presents strong potential as an eco-friendly and efficient biomaterial for heavy metal remediation.

Abstract

The concepts of differential and integral are important topics in chemistry mathematics courses. Based on the number of subtopics, differential and integral concepts are covered on average more than 40% in chemistry mathematics books. Several previous studies reported findings that differential and integral concepts are still difficult for students to understand. This research aims to evaluate the previous lecture program and propose an alternative learning design to help students more easily understand those concepts. In this study, we developed a practicum by adopting Plomp’s model, which were collecting, designing, trying, and revising the product. The practicum design was developed for heating process of glucose solution. Those chemicals were chosen because the materials obtained are relatively easy, cheap, and safe, so it is very possible to practice it in the laboratory. We used Maple to model the heating process phenomenon. The results show that the differential and integral concepts can be applied to model the heating process of glucose solution by using Maple. This research is limited to simulations. Therefore, the suggestion for further research is to conduct field trials to determine the impact of implementing learning design in increasing students' understanding of differential and integral concepts.

Abstract

One of the factors that have become an obstacle in the development of techno-logy to use ocean wave energy as a renewable energy source is the lack of human resources who have expertise in this field. Therefore, in the long term, it is necessary to introduce basic knowledge to the young generation about wave energy and other renew-able energies and even must equip them with important skills such as creative thinking skills. This study aims to introduce students to how to utilize ocean waves as renewable energy while at the same time developing student creative thinking skills through semi-assisted project-based learning. This type of research is weak experiment research with one group pretest-posttest design research. The research was conducted on 31 pre-service physics physics teachers who were taking environmental physics lectures at a teacher training university in West Nusa Tenggara. The performance appraisal data were analyzed descriptively while the test result data were analyzed using the N-gain and the Wilcoxon test. Based on the results of data analysis, it was obtained <g> = 0.725, which means that there was a high increase in students' mastery of the concept of using ocean waves as a renewable energy source. In addition, the results of the performance appraisal data (score > 3) indicated that at each stage of learning, students were provided with indicators of creative thinking skills with very satisfied categories. Therefore, it can be concluded that environmental physics lectures using semi-assisted project-based learning able to improve students' mastery of concepts and creative thinking skills.

Abstract

The essence of mathematics is a thought process in constructing, applying abstract ideas, and their logical interrelationships. This process is essential in solving quantitative and qualitative physics problems, where abstract ideas are required to represent physical phenomena. This study aims to give detail description of the process of mathematical methods for physics lectures. Improvement in pre-service physics teachers' critical thinking is designed to strengthen their critical thinking and problem-solving skills. The methodology of research is qualitative descriptive. The research subjects were 97 pre-service physics teachers who had followed the mathematical methods for physics courses and teaching lecturers. Data collection consisted of questionnaires, and interviews. Observations are needed for describing the implementation of mathematical methods for physics courses, document analysis, and data collection, including lesson plan and assessment. The results showed that mathematical methods for physics courses need improvement in the learning process. It is concluded that lecture activities integrating computers into physics and mathematics are necessary to be implemented. It is expected that the program will improve students' ability in problem-solving, critical thinking skills, communication, digital era literacy, creative and innovative creations, and group work. Specifically, implementation of the program in the ordinary differential equations course can provide learning experiences to students regarding the process of reasoning in physics using mathematical principles.

Abstract

This study developed a teaching strategy to strengthen scientific reasoning. The study proceeded through preliminary investigation, prototype design, iterative try-outs, and implementation. The preliminary study showed that differential and integral topics in classroom practice remained largely procedural and did not explicitly integrate modelling empirical data. In response, a strategy was designed to connect chemical phenomena, mathematical, and Maple-assisted. Participants were undergraduate students from two universities. Try-out I involved 17 Chemistry students and Try-out II involved 10 Chemistry Education students at university in Palangka Raya, Central Kalimantan, whereas the final implementation involved 30 undergraduate students at university in Bandung, West Java. Comprehension scores increased from 33.22 to 64.88 in Try-out I and from 33.82 to 70.59 in Try-out II. In the final implementation, mean scientific reasoning scores increased from 34.40 to 72.27 for the mathematical aspect and from 31.85 to 70.65 for the chemistry aspect. Gains in scientific reasoning were very strongly correlated with gains in differential–integral understanding (r = 0.969, p < 0.001). These findings indicate that the developed strategy supports scientific reasoning by linking chemical phenomena, mathematical modelling, and Maple. The strategy should be examined in larger samples and other chemistry topics.
