Abstract

This study aimed to develop and evaluate a Citizen Science–based thermochemistry teaching module as an innovative learning resource in senior high school chemistry. The study employed a research and development design using the ADDIE model, encompassing analysis, design, development, implementation, and evaluation stages. The participants were 119 eleventh-grade students from a public senior high school in Gorontalo. Data were collected through expert validation, teacher and student practicality questionnaires, scientific literacy tests, and environmental awareness questionnaires. The results indicated that the developed module achieved high validity and practicality and demonstrated effective learning outcomes, as reflected in improved scientific literacy and increased levels of environmental awareness after implementation. The novelty of this study lies in the integration of the Citizen Science approach into a thermochemistry module that explicitly connects abstract energy concepts with authentic environmental exploration activities, an area that has been rarely addressed in chemistry education research. These findings suggest that the developed module is feasible and pedagogically meaningful for supporting scientific literacy and environmental awareness in senior high school chemistry learning.

Abstract

Mercury (Hg) pollution caused by small-scale gold mining activities poses a serious environmental threat due to its toxic nature, tendency to accumulate, and ability to contaminate water and soil. This study aims to analyse the chemical and morphological characteristics of activated carbon derived from the roots and rhizomes of the snake plant (Sansevieria trifasciata) as a biosorbent, to determine its adsorption capacity in reducing mercury levels in gold mine tailings, and to investigate the influence of biosorbent mass and contact time on adsorption capacity. SEM characterisation results showed that activated carbon had more open pores than unactivated carbon. FT-IR analysis identified the presence of active functional groups, namely –OH, C=C, C–H and C–O, which play a role in the adsorption of mercury ions. The moisture content test yielded a result of 9.2639%, which meets the SNI 06-3730-1995 standard, while the ash content was found to be 17.5682%. Analysis using an atomic absorption spectrophotometer (AAS) showed that the initial mercury concentration in the tailing waste was 0.0263 mg/L and could be reduced to 0.0132 mg/L with 1 g of biosorbent, 0.0045 mg/L with 3 g, and 0 mg/L with 5 g of biosorbent after 360 minutes of contact time.

Abstract

Sacha inchi (Plukenetia volubilis L.) seed oil is rich in polyunsaturated fatty acids, such as alpha-linolenic acid (ω-3) and linoleic acid (ω-6), which are beneficial for health but are susceptible to oxidation. This study aimed to develop a stable and efficient microencapsulation system to protect oil from oxidative degradation using a complex coacervation method with gelatin and sodium alginate as coating materials, and calcium chloride (CaCl2, 2%) as a crosslinking agent. The process was carried out at pH 3.75, with homogenization at 12,000 rpm for 7 minutes, followed by low-temperature drying. Characterization included yield, encapsulation efficiency, moisture content, particle size, and the morphology of the microcapsules. The results showed a yield of 75.00 ± 2.10%, an encapsulation efficiency of 93.85 ± 0.93%, and a moisture content of 11.26 ± 1.37%. Dynamic Light Scattering-based Particle Size Analyzer analysis showed a hydrodynamic diameter of~0.100 µm (PDI 0.321) with good dispersion (88.4% transmittance). In the meantime, Scanning Electron Microscope observations revealed a spherical morphology with a smooth, crack-free surface. The gelatin-sodium alginate combination proved effective as a coating material, yielding microcapsules with high efficiency, good physical stability, and potential applications in functional food products and nutraceutical supplements.

Abstract

This study aimed to develop a differentiated teaching module to enhance students' scientific argumentation skills on chemical bonding material. The method used was Research and Development (R&D) with the 4D model (Define, Design, Develop, Disseminate). Validation results from experts showed that the developed differentiated teaching module was highly valid (92% and 94%), very practical (100% and 97%), and effective, with more than 80% of students achieving the minimum competency standard (KKM) and an average score of 88. The improvement in scientific argumentation skills was reflected in the average pre-test score of 64, which increased to 80 in the post-test. Specifically, the indicators of scientific argumentation showed improvement: claims increased from 62.9% to 75.4%, data from 66.3% to 84%, warrants from 67.8% to 82.1%, and backings from 68.4% to 79.4%. The increase in scientific argumentation scores from pre-test to post-test indicates that the developed teaching module was effective in helping students hone their argumentative skills. However, the ability to formulate claims and backings still requires reinforcement, as they demand a more complex understanding. Nevertheless, this improvement suggests that the differentiated teaching module created and implemented can strengthen students' scientific argumentation skills in understanding chemical bonding material, making it recommended for broader application, especially in science education.

Abstract

Despite the importance of understanding reaction rate concepts in chemistry, students often struggle with abstract content and low engagement in traditional learning settings. Conventional teaching methods tend to emphasize rote memorization, limiting opportunities for critical thinking and problem-solving. This study investigated the influence of ChatGPT-assisted Problem-Based Learning (PBL) on students’ learning outcomes in reaction rate material. A quasi-experimental design with a non-equivalent control group was employed, involving two Class XI groups at SMA Negeri 1 Kabila: XI A as the experimental group (using ChatGPT-assisted PBL) and XI B as the control group (receiving conventional instruction). Learning outcomes were measured using an essay test aligned with cognitive indicators. Results showed greater improvement in the experimental group, with a posttest average of 78.68 compared to 69.23 in the control group. Independent sample t-test analysis revealed a significant difference between groups (p = 0.001 < 0.05), and the N-Gain score indicated a higher improvement category in the experimental class. These findings suggest that integrating ChatGPT into PBL enhances students’ understanding of reaction rate concepts and supports more effective learning, highlighting the potential of AI-assisted strategies in chemistry education.
