Abstract

The rapid advancement of information technology has encouraged small and medium-sized enterprises to shift from manual operational procedures to structured digital systems. However, many small printing businesses continue to face delays, data inconsistencies, and limited real-time monitoring due to conventional order management practices. These challenges highlight the need for a more responsive and efficient ordering system capable of improving transaction accuracy and service delivery speed. This study addresses the issue by developing a web-based ordering system using an iterative Agile Scrum approach, followed by a comprehensive performance evaluation through simulated concurrent user testing. The results show a substantial improvement in system responsiveness, with user data retrieval time decreasing from 11,228 ms to 2,148 ms (an 80.9% improvement) and order processing time reduced from 16,954 ms to 4,697 ms (a 72.3% improvement), resulting in an overall average efficiency gain of 76.6%. The integration of Redis caching significantly enhances system performance, stability, and load distribution, addressing the current gap in Redis implementation for small-scale printing environments. This study demonstrates that adopting a hybrid data-handling architecture can provide a scalable, reliable, and high-performance solution for digital ordering processes, enabling small enterprises to improve operational efficiency and customer satisfaction.

Abstract

Indonesia faces significant challenges in improving English proficiency among its population. According to the EF Education First English Proficiency Index 2023, Indonesia ranks 79th out of 113 countries. On the other hand, the current generation begins to forget cultural elements such as folklore or myths that have been passed down from the nation's ancestors. This study aims to design an English learning application for children and teenagers using the design thinking method. The stages of design thinking that are used are empathize, define, ideate, prototyping, and testing. In the prototyping stage, low-fidelity and high-fidelity prototypes were created to visualize the application's design and functionality. Testing was conducted by using task scenarios and the System Usability Scale (SUS). The task scenario testing results revealed that the effectiveness and efficiency rate of 85.71%, indicated that most tasks could be completed successfully by users. The SUS testing results showed an average score of 86.5%, indicated that the application has a high level of usability and well-received by users. Thus, the application's interface is considered easy to use and effective in supporting the English learning process for the target users. This research provides a positive contribution to the development of educational applications using a design thinking approach.
