Abstract

This study aims to investigate students’ learning obstacles in understanding Green Chemistry within the context of a soap-making activity. As sustainability becomes an increasingly important issue in science education, it is essential to understand how students engage with environmentally oriented chemistry concepts. This study employs qualitative case study approach. The participants consisted of five grade XI students (second-year high school), comprising two boys and three girls. The interviews were conducted at a private school in Bandung. Data were collected through semi-structured interviews with five main questions. The responses were analyzed using thematic analysis to identify key themes related to students’ learning challenges in understanding green chemistry, which were categorized into five main themes. The findings reveal that students face significant challenges in understanding Green Chemistry, particularly due to abstract concepts, limited classroom engagement, and teacher-centered instruction. Moreover, students often struggle to connect the theoretical principles of Green Chemistry with real-life applications, such as waste reduction or the use of renewable materials in everyday chemical processes. These findings highlight the importance of designing more interactive, context-based, and student-centered learning strategies. It is expected that the results of this study can serve as a foundation for developing instructional designs that better support students’ understanding of sustainability-oriented chemistry.

Abstract

This study aims to utilize banana pseudostem and coconut pulp waste as raw materials for biomass briquettes, evaluate their physical and thermal characteristics, and assess their potential as alternative fuel sources. The research methods included drying, grinding, mixing, molding, and briquette testing. Characterization was conducted through hardness testing using a digital sclerometer, morphological and particle size analysis using a digital microscope, calorific value measurement using a bomb calorimeter, and thermal degradation analysis using Thermogravimetric Analysis (TGA). The hardness test showed that pure banana pseudostem briquettes had the highest compressive strength according to the P3HH standard, while the addition of coconut pulp tended to reduce it. Increasing the proportion of coconut pulp produced larger average particle sizes, affecting briquette porosity. The highest calorific value, 16,829.73 J/g, was obtained from a 50:50 composition, indicating that the oil and lignin content in coconut pulp contributes to combustion energy. TGA analysis revealed that briquettes with higher banana pseudostem content exhibited greater heat resistance, while those with more coconut pulp ignited faster and left less residue. In conclusion, briquettes made from banana pseudostem and coconut pulp can be used as an alternative solid fuel, with compositions adjustable according to the desired energy output and combustion characteristics.

Abstract

Students’ science literacy in Indonesia remains relatively low and needs to be improved through contextual and meaningful learning. One approach that can be taken is to integrate Problem-Based Learning (PBL) and Education for Sustainable Development (ESD) into interactive teaching materials. This study aims to develop PBL-based e-worksheets integrated with ESD on the topic of buffer systems within the context of the cheese industry to enhance students’ science literacy. The method used is Design and Development Research (DDR), which includes the planning, production, and evaluation stages. The planning stage was conducted through a need analysis involving high school chemistry teachers, while the production stage involved the design and development of the e-worksheet, which was then validated by two lecturers and two chemistry teachers. The evaluation stage was conducted through a pilot test with 30 11th-grade high school students. The research results indicate that the developed e-worksheet possesses excellent quality, with a 100% feasibility rate across all evaluation aspects. Pilot test results show that students’ science literacy falls within the good to excellent categories, particularly regarding the ability to organize information, analyze data, and connect concepts to sustainability issues such as the SDGs and the circular economy. However, their ability to formulate problems and engage in deep scientific reasoning still needs improvement. Thus, this e-worksheet is deemed suitable for use and can foster science literacy through contextual, interactive, and sustainability-oriented learning.

Abstract

This research aims to design and implement sharing and jumping task learning on inorganic compound nomenclature material to foster critical thinking skills. The applied didactical design research (Didactical Design Research) consists of 3 stages, namely: Didactical situation analysis before learning in the form of hypothetical didactical design including Didactical Pedagogical Anticipation (ADP), Metapedadidactical Analysis, and Retrospective Analysis after learning. The research subjects were 28 class X high school students. The research results found that: (1) The sharing and jumping task learning design on the nomenclature of inorganic compounds is quite effective in developing students' critical thinking skills. (2) Based on transcript analysis, most students can develop critical thinking skills, especially asking and answering clarifying/challenging questions. However, students have difficulty developing critical thinking skills in making and assessing valuable assessments. The sharing and jumping task learning design developed can be used as an alternative design in the nomenclature of inorganic compounds.

Abstract

Global environmental challenges such as climate change, pollution, and ecosystem degradation require urgent responses, and education plays a strategic role in building environmental literacy. This study aimed to evaluate the readiness of higher education curricula in supporting sustainable learning in Environmental Chemistry courses and their alignment with the Sustainable Development Goals (SDGs). The research used a descriptive approach involving curriculum and lesson plan analysis, student surveys, and interviews with lecturers and program heads at a state university in Aceh Province, Indonesia. The findings show that while the curriculum includes relevant topics such as pollution and climate change, the integration of emerging issues and practical learning methods remains limited. Students demonstrated positive attitudes and awareness toward environmental sustainability, but their active involvement in practical actions was still low. Recommendations include the explicit integration of SDGs in course plans, diversification of teaching strategies through fieldwork and case studies, and fostering interdisciplinary collaboration. Overall, the study concludes that the curriculum provides a strong foundation but requires strategic improvements to enhance its relevance and impact. Aligning academic programs with global and local environmental challenges will enable higher education to prepare students as proactive agents of sustainable development.
