Abstract

This study explores the optimism of Chemistry students at Medan State University towards the use of artificial intelligence (AI) in writing academic texts. PKSM 23B students were interviewed using a qualitative approach to conduct this study. The results showed that most students saw AI as a great tool to trouble academic texts, as well as the challenges and opportunities of using AI. However, there were concerns about the possibility of engaging in plagiarism and reducing critical thinking skills. The limitations of AI infrastructure and information quality are additional problems. This study emphasizes the importance of academic ethics training, better digital literacy, and equal access to technology. This study suggests that a balanced strategy must be used to utilize technology and build students' intellectual abilities independently so that AI can be used effectively in the academic world.

Abstract

Natural dyes extracted from butterfly pea flowers (Clitoria ternatea L.) hold significant potential as alternatives to synthetic dyes in the food and textile industries. This study aims to evaluate the effectiveness of citric acid isolated from bilimbi (Averrhoa bilimbi L.) as a solvent for extracting anthocyanin pigments from butterfly pea flowers. Ultrasonic extraction was conducted using different solvents (citric acid and ethanol) and varying extraction durations. The results showed that the extract yield ranged from 2.6% to 5.5%, with an average of 3.99%. Ethanol produced a higher yield than citric acid; however, citric acid significantly reduced the extract’s pH to a range of 1–6, potentially enhancing anthocyanin pigment stability. Additionally, extraction time positively influenced yield up to an optimal point, after which degradation of active compounds led to a decline. These findings suggest that bilimbi-derived citric acid has potential as an eco-friendly solvent for natural dye production, though further optimization is needed to enhance extraction efficiency and color stability.
