Abstract

Students who have a strong understanding of concepts, good use of terminology, and the ability to invent environmentally friendly products, they can become effective drivers of change. This will enable them to support Green Chemistry innovations and practices in the future. provides practical experience to students, allows them to use the ideas they learn in real-life situations, and encourages them to show greater concern for environmental sustainability. This survey study took a sample of 28 individuals. Students' understanding of the concept of Green Chemistry is still in the "fairly good" category, with an average of 1.83. However, this is a good result, and their understanding can still be improved with more in-depth learning methods and greater emphasis on this concept in the curriculum. A good understanding of Green Chemistry terminology was positive, with an average of 2.58. This shows that students can communicate well using relevant words in the field of green chemistry; this is crucial for participating in discussions and developing sustainable projects. In addition, students' ability to find environmentally friendly items is quite good, with a mean of 2.36. Improving this ability continuously can help them support more sustainable products and practices in their daily lives.

Abstract

This community service project seeks to boost the added value and welfare of maize producers through the creation of corn flour products. Corn flour products have tremendous potential in enhancing the economics of the community, especially corn farmers, by delivering food products manufactured from maize that have wonderful tastes and high nutritious value. In addition, the food products created are very popular and have vast market potential. Through the training and mentoring approach of the IbM activities, the community obtained important information and knowledge, enabling them to create innovation and enterprise in the maize sector. The outcomes of this activity demonstrate that this service program not only enhances the skills and knowledge of the community, but also helps the improvement of their economic wellbeing in a sustainable manner.

Abstract

Education on the dangers of using food additives is an effort to enhance the public's understanding of the risks associated with consuming foods containing additives. The increased consumption of additives correlates with the rising intake of processed foods. The objective of this community engagement initiative is to raise awareness among the public regarding the potential hazards associated with the use of food additives. The methods employed include lecture-style presentations and discussions. The community gains an understanding of various types of additives commonly used in food, with an emphasis on their benefits, such as prolonging the shelf life of food. However, the education also highlights associated risks, including potential adverse effects on health like allergies, digestive disorders, and long-term effects that are not fully understood. The activities took place in the village of Hutadaa in Gorontalo Regency, with a total of 18 participants. The participants were enthusiastic, and increased knowledge was evident through the questions raised during the session.

Abstract

Stoichiometry is a fundamental concept in chemistry that requires students to coordinate symbolic calculations with submicroscopic representations of particles and reactions. However, previous studies consistently show that students often rely on algorithmic procedures without developing coherent particle-level reasoning, leading to persistent misconceptions. This representational gap remains a major challenge in Basic Chemistry instruction. Therefore, this study aimed to examine the effectiveness of audiovisual-supported Problem-Based Learning (PBL) in enhancing students’ submicroscopic representational ability in stoichiometry using a two-tier diagnostic approach. A quasi-experimental design with a posttest-only comparison was employed involving 33 undergraduate students enrolled in a Basic Chemistry course. Participants were divided into two groups with equivalent initial ability distributions: an experimental group receiving PBL integrated with audiovisual media (n = 16) and a control group receiving PBL without audiovisual support (n = 17). Students’ submicroscopic understanding was measured using a two-tier multiple-choice diagnostic test assessing both response accuracy and particle-level reasoning. Data were analyzed through descriptive statistics, diagnostic category profiling, and effect size estimation. The results reveal that the experimental group demonstrated substantially higher levels of coherent submicroscopic representation and significantly lower misconception rates than the control group. Learning gains were consistent across all stoichiometry subtopics, with particularly strong effects observed in relational and inferential tasks such as particle ratio interpretation and limiting-reactant reasoning (Cohen’s d = 1.41). These findings indicate that audiovisual-supported PBL effectively facilitates students’ transition from procedural problem solving to meaningful particle-level understanding. The study underscores the importance of integrating representationally rich instructional media and diagnostic assessments to promote deeper conceptual learning in stoichiometry and chemistry education.
