Abstract

Determining a college major is an important decision that students often make without objective consideration, risking a mismatch between interests and abilities, which can ultimately lead to changing majors or dropping out. This research aims to design and implement a web-based Decision Support System (DSS) capable of providing objective major recommendations by considering students' academic abilities. The Weighted Product (WP) method was chosen due to its capability in handling multi-criteria problems with proportional weighting and automatic normalization. The system was developed using a technology stack of PHP, MySQL, HTML, CSS, and JavaScript, with XAMPP as the local server. Data was collected from 30 students of grade XII Science program at SMAN 8 Kota Serang, covering scores from six subjects (Mathematics, English, Indonesian, Physics, Chemistry, Biology) and five alternative engineering majors (Electrical Engineering, Mechanical Engineering, Civil Engineering, Chemical Engineering, Informatics). Testing results show that the system can generate major recommendations in less than 2 seconds. Accuracy evaluation using blackbox testing and cross-validation between final grades and try-out scores resulted in a compatibility rate of 36.67% for recommendations based on try-out scores, which is statistically more accurate compared to final grade-based recommendations (with 63.33% incompatibility). These findings indicate that try-out data is more representative in predicting academic potential for university admission. This system has proven to be effective, efficient, and has significant potential to be adopted by educational institutions as a data-based counseling tool

Abstract

This study aims to analyze a unique phenomenon identified during an international community service activity in Malaysia, namely the refusal of cash payments in Indonesian rupiah and Singapore dollars in several souvenir shops, while digital payments based on QRIS were accepted. This phenomenon is noteworthy as it reflects a shift in cross-border transaction practices from conventional systems toward regionally integrated digital payment systems. The study employs a descriptive qualitative approach through field observation and a literature review related to payment connectivity between Bank Indonesia and Bank Negara Malaysia. The analysis focuses on the implications of digital economy development for transaction efficiency and MSME empowerment. The findings indicate that cross-border QR code interoperability not only enhances transaction efficiency and convenience but also strengthens financial inclusion and ASEAN economic integration. These results suggest that payment digitalization has the potential to become a new model of technology-based economic integration in Southeast Asia. This study provides a contemporary perspective on the transformation of cross-border payment systems and opens further discussion on the future of the regional digital economy.
