IT vendor selection is a strategic decision that affects service quality, cost efficiency, and the sustainability of a company’s information technology systems. PT Investasi Bangun Bangsa Indonesia (PT IBBI) faces challenges in its IT vendor selection process, which is still conducted manually and tends to be subjective, potentially leading to suboptimal decisions. This study aims to design and develop a web-based decision support system for IT vendor selection using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method is applied to support multi-criteria decision-making by ranking vendors based on their proximity to the positive ideal solution and their distance from the negative ideal solution. The criteria considered include price, service quality, implementation time, portfolio, reliability, and uptime. The research methodology includes system requirements analysis, a literature review, data collection through observation and interviews, system design, implementation of the TOPSIS algorithm, and system testing using black-box testing. The results indicate that the proposed system is capable of providing objective and measurable IT vendor recommendations. Therefore, this decision support system can enhance the effectiveness and efficiency of the IT vendor selection process at PT IBBI while minimizing the risk of decision-making errors.

Global education today increasingly emphasizes the importance of introducing students to cultural, economic, and political diversity around the world. In this context, the introduction of G20 member countries becomes relevant due to their roles in the global economy and international policies, which are also rarely addressed in school lessons about the G20 countries. To facilitate an engaging and interactive learning process, we designed a 3D-based educational media application using Augmented Reality (AR) methods and the FAST (Features from Accelerated Segment Test) Corner detection algorithm to define how well images can be detected and tracked using the Vuforia SDK. This application design aims to provide a profound and captivating learning experience for users. With AR technology, users can directly interact with 3D models of G20 member countries, such as learning about iconic buildings, cultural objects, as well as relevant economic and political information. The application also includes interactive features, including knowledge quizzes and educational games to enhance user engagement. The application development method involves designing an intuitive user interface, developing accurate 3D models, and integrating responsive AR technology. Additionally, the learning content is comprehensively structured, considering various important aspects of each G20 member country. Thus, this application can be an effective tool to enhance users' understanding of global diversity and motivate them to learn more about the roles and contributions of G20 member countries in the modern world context.

The assessment of the best employees at PT Prestasi Retail Innovation has traditionally been conducted manually, which is considered inefficient and tends to be subjective. This study aims to design and develop a Decision Support System (DSS) based on Java using the Profile Matching method as a solution to enhance objectivity, efficiency, and transparency in the employee selection process. The system applies evaluation criteria and sub-criteria determined by the company, such as discipline, creativity, work ethic, attendance, and performance. The research methods include observation, documentation, and interviews to identify system requirements and assessment parameters. The system is developed using an object-oriented approach with the support of Unified Modeling Language (UML), implemented with the Java programming language, and integrated with a MySQL database. The Profile Matching method is applied through GAP analysis between employees’ actual profiles and the ideal profile, which is then processed into employee rankings. The results show that the system successfully automates the evaluation process, generates more objective recommendations, and supports decision-making related to promotions, rewards, and performance evaluation. The application of a DSS based on the Profile Matching method has proven to provide real benefits for management in human resource management.
