In today's fast-paced food service industry, the efficiency of queue management is vital to operational success, profitability, and customer satisfaction. This study evaluates an integrated queue management system's impact on these critical areas. The results show an average satisfaction score of 80.11% from customers and 90.37% from food outlet owners, demonstrating the system's strong effectiveness. The research focused on the importance of reducing perceived waiting times through real-time updates, which enhance customer tolerance and satisfaction. By combining online and onsite ordering, the system provides real-time updates, order tracking, and notifications to boost efficiency and minimize cancellations. Despite some identified weaknesses, such as the absence of direct customer reviews and existing bugs, the system holds significant potential for improving user experience. These findings highlight the necessity for continuous development and maintenance to optimize the system further. Overall, this approach promises to advance the operational capabilities and customer satisfaction levels of food outlets.

This study aims to measure the level of effectiveness of the use of flash cards and applications based on Augmented Reality as a learning aid. The use of Android applications and AR cards that can also function as flash cards has proven to attract interest and increase student motivation in learning. Number recognition material and addition of unit numbers are chosen as the initial experiment stage which aims to introduce the use of assistive devices in the form of tablet PCs or smartphones to the children. Based on the results of the study, both teachers and students felt helped by the existence of this application as a variety of learning media. The research method used in this study is Multiple Baseline Design Across Subjects, while the sampling technique used is census sampling technique.
