Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in the economy, but they still face challenges in promotion, particularly in utilizing digital media. MSMEs in Bandar Kumbul Village generally still use traditional methods and are unable to create engaging promotional content. This activity aims to improve MSMEs' understanding and skills in using the Canva application as a digital promotional tool. The method used is community service through preparation, implementation, and evaluation stages using the 70/20/10 learning model. Data was collected through observation, interviews, and pre- and post-tests. The results show an increase in participants' knowledge and skills in creating promotional content such as posters, banners, and social media, as well as an increase in digital media utilization and understanding of branding. Therefore, Canva is effective in improving the quality of promotions, expanding market reach, and enhancing the competitiveness of MSMEs.

Abstract

The development of information technology has driven digital transformation in the banking sector, particularly through e-banking services that provide convenience, speed, and flexibility for users in conducting financial transactions. The BRI Mobile (BRImo) application, as a digital service of Bank Rakyat Indonesia, plays an important role in improving service quality for customers. However, the emergence of negative perceptions regarding transaction notifications, along with varying user experiences, may affect user satisfaction and loyalty levels. The main problem in this study is that the patterns of user satisfaction and loyalty, as well as the most influential factors affecting both aspects, have not been clearly identified. This study aims to analyze the level of user satisfaction and loyalty toward the BRI Mobile application and to identify the dominant factors influencing them, namely ease of use, security, trust, and system performance. The research employs a quantitative approach using data mining techniques, specifically the K-Means Clustering algorithm to group users based on satisfaction levels, and a Decision Tree to determine the most influential factors affecting user loyalty. Data were collected through questionnaires distributed to 100 active BRImo users. The results show that users can be grouped into several clusters with different satisfaction characteristics. In addition, the Decision Tree analysis reveals that system performance is the most dominant factor influencing user satisfaction and loyalty, followed by ease of use, security, and trust. Overall, the combination of K-Means Clustering and Decision Tree methods provides a more comprehensive understanding of user satisfaction and loyalty patterns, and can serve as a basis for strategic decision-making to improve the quality of the BRI Mobile application services.

Abstract

Church libraries play a crucial role in supporting literacy and spiritual growth by providing various reading materials such as religious books, Bible references, and other supporting literature. However, manual library management still presents significant challenges, such as recording errors, book discrepancies, inaccurate fine calculations, and difficulty in accessing past reports, which hampers system efficiency. As the collection grows, the manual system becomes increasingly inefficient, prone to data loss, and cumbersome for information retrieval. Therefore, a web-based library management system is needed to automate the processes of collection management, book borrowing, and return, while ensuring data security and accuracy. This study aims to design and develop a web-based library information system for GBI Antiokhia, utilizing the AdonisJS technology stack, to address these challenges. The system is developed using the Prototyping method, ensuring user interaction and feedback throughout the development process. The system’s features include member data management, book management, borrowing and returning books, fine management, and report generation, all built to be efficient, secure, and user-friendly. This research also examines how the implemented system can solve the existing library management issues and improve operational effectiveness.
