Abstract

Lavender contains active compounds such as flavonoids, tannins, coumarins, phytosterols, and minerals, which possess antioxidant properties and pharmacological potential. This study optimized the extraction process of lavender flowers to maximize bioactive phenolic and flavonoid yields. Ultrasonic-assisted extraction (UAE) was employed, and optimization was conducted using a Box-Behnken design in Design Expert 13.0.5.0 software. The influence of ethanol concentration, liquid-solid ratio (LSR), and extraction time on total phenolic content (TPC) and total flavonoid content (TFC) was evaluated. Results revealed that LSR significantly impacted the responses. Optimal conditions were determined as an LSR of 50 mL/g, extraction time of 26 minutes, and ethanol concentration of 26.12%. Validation under these conditions yielded a TPC of 152.26 mg GAE/g DE and a TFC of 68.59 mg QE/g DE, with percentage errors of −7.7% and 3.5%, respectively, demonstrating excellent agreement with the predicted values.

Abstract

This study aims to analyse the effectiveness of using QRIS among Asahan University students, focusing on aspects of convenience, security, efficiency, and student acceptance of digital payment systems. This research uses a descriptive quantitative approach with a survey method, where data is collected through distributing questionnaires to students as respondents. The results showed that the majority of Asahan University students have used QRIS in their daily transaction activities, and generally gave positive responses to its use. Asahan University students stated that QRIS made non-cash transactions easier, and felt satisfied using it. In addition, students stated that QRIS helps reduce the risk of carrying cash, and consider this system efficient and in accordance with the needs of the times. QRIS is also considered to support a cashless lifestyle by Asahan University students. Nevertheless, there are challenges in the form of technical obstacles such as internet networks and limited understanding of some users. In addition, there are still some students who feel more comfortable using cash. Overall, this study concludes that QRIS is quite effectively used by Asahan University students as a practical, safe, and efficient digital payment tool. The findings also show that QRIS has great potential in strengthening digital financial literacy among the younger generation and encouraging the creation of a culture of non- cash transactions in the campus environmentKeywords: QRIS, Non-Cash Transactions, Effectiveness, digital payment system, Student Perception.
