Abstract

Corn is the main commodity product and the flagship of Gorontalo Province, ranked in the top 10 in Indonesia. In Daenaa Village, West Limboto Subdistrict, corn has not been maximally processed to increase creative economic growth due to limited knowledge and processing techniques, even though Daenaa Village is a corn production center in Gorontalo Regency. This community service activity aims to improve the skills and income of the residents of Daenaa Village, West Limboto District, through training in making processed corn products such as tortilla chips and corn milk. The training on making tortilla chips involves the process of boiling corn with lime water, mixing spices, adding corn flour, to shaping and drying to produce a durable ready-to-fry product. Meanwhile, the process of making corn milk includes boiling young corn, grinding, filtering, and adding sugar, flavor, and CMC to create a nutritious drink with a soft texture. The final product is hygienically packaged and labeled to increase its selling value. The results of the activity showed an increase in participants' knowledge and skills in processing corn into value-added products that have the potential to become micro-enterprises. Hopefully, this program can be the first step for the people of Daenaa Village to utilize local potential as a new source of sustainable income.

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.

Abstract

Students’ higher-order thinking skills in chemistry remain low due to the dominance of conventional teaching methods. This study aimed to investigate the effect of the CUPS (Conceptual Understanding Procedures) learning model on students’ higher-order thinking skills in the topic of basic laws of chemistry. Using a quasi-experimental design with a pretest-posttest control group, two classes of 28 students each from SMAN 1 Suwawa were selected as the experimental (CUPS-based learning) and control (conventional learning) groups. Data were analyzed using independent sample t-test. Results showed a greater improvement in the experimental class (pretest = 61, posttest = 79) compared to the control class (pretest = 39, posttest = 64). A significant difference was found between the groups (p = 0.001 < 0.05), leading to the rejection of the null hypothesis. These findings indicate that the CUPS learning model positively enhances students’ higher-order thinking skills, suggesting its potential for improving chemistry education
