Abstract

This study analyzes the queuing system at XYZ fast food restaurant in Batam City to improve service efficiency and customer satisfaction. Observations were conducted over eight hours on Saturday, April 6th, 2024, from 2:00 PM to 10:00 PM. Data collected included arrival patterns, service time, and customer wait time. Using the queuing model [M/G/2/FIFO/4/∞], it was found that two servers are optimal. The average customer wait time in the system is 4.938 minutes, which is lower than the customer's aspirational wait time of 10 minutes. The system's utility reached  84.33%, indicating sufficient efficiency. Practical recommendations for XYZ fast food restaurant management are to maintain two servers to reduce wait time and increase customer satisfaction.

Abstract

Purpose: This program aimed to strengthen digital financial literacy among youth in Batam, focusing on safe and practical savings and investment strategies that are aligned with current technologies. Methodology/approach: The community service program (PKM) was conducted in three stages: preparation (materials, partner coordination, outreach), implementation (talks, hands-on use of e-wallets/auto-debit/micro-investing apps, discussions), and evaluation (pre- and post-questionnaires and feedback). Results/findings: Most participants rated the materials as clear and useful, and many reported better knowledge and readiness to adopt digital saving and try beginner-friendly instruments introduced during the session. The participants represented diverse ages and education levels and included students and MSMEs. Conclusions: The PKM program effectively enhanced digital financial literacy and motivated participants to manage their finances in a modern context. Most participants clearly understood the material, found it relevant, and showed improved knowledge and readiness to save and invest digitally. Despite challenges related to time constraints and varying levels of digital literacy, the program positively influenced the adoption of wise financial behavior in the technological era. Limitations: Short duration, varied baseline literacy, and intermittent Internet access limited deeper practice; long-term behavioral outcomes were not tracked. Contribution: The PKM effectively improved essential competencies in digital money management and encouraged prudent technology-enabled behaviors among youth. We recommend follow-up coaching and long-term monitoring to consolidate saving habits and safe, small-ticket investing.
