Abstract

The development of blockchain technology, especially Non-Fungible Tokens (NFT), has created challenges for investors in determining the right investment value. This study aims to develop a decision support system using the Weighted Aggregated Sum Product Assessment (WASPAS) method and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to assess NFT as an investment alternative. The research process involves several stages, including problem identification, problem analysis, literature study, data collection, and data analysis. The criteria used in assessing NFT include price, owner/origin, format, rarity, and industry, each with a set weight. After collecting data on various NFTs, a decision matrix is ​​constructed and normalized to reflect the performance of each alternative. The WASPAS and TOPSIS methods are used to assign preference values ​​to each NFT alternative based on their proximity to the positive and negative ideal solutions. The analysis results show that NFT named "Video Clip" (A3) has the highest value with a preference of 0.671, followed by "Song" (A5) with a value of 0.445, and "Book" (A2) with a value of 0.465. Meanwhile, "Selvie Photo" (A4) and "Photo" (A1) have the lowest preferences of 0.196 and 0.189, respectively. This study contributes to NFT investment decision making, by providing a systematic and data-driven approach that can reduce risk and maximize potential profits for investors. The combination of WASPAS and TOPSIS methods offers a comprehensive framework for NFT valuation, so that it can be adopted by investors and NFT platform developers in evaluating the value of digital assets more effectively.

Abstract

Facilities and infrastructure are a crucial part of the development and construction of a region or country, one of which is public bus transport, which plays an important role in an efficient transport system. The transition from conventional to digital systems is not always easy for the community, especially in the city of Medan. Surveys have shown that people have difficulty using the Trans Metro Deli digital bus transport system to obtain information about bus routes and schedules, and to make cashless payments that were previously made in cash. To overcome this problem, a simulation video of its use was created based on 2-Dimensional animation using the Motion Graphic method with Adobe Flash CS6. Motion Graphic is a graphic design science that combines various elements such as illustration, typography, photography and animation to create dynamic and audiovisually appealing visuals. The output resulted in the form of a 2-Dimensional animation-based simulation video in the use of Trans Metro Deli bus transport using the Teman Bus application. The results of this research are expected to help the city of Medan face the challenges of transitioning from conventional transport to digital public transport, as well as increase public interest in using the service in the future.

Abstract

The internet has become a secondary necessity that supports daily activities such as working, studying, and exchanging information. High-traffic websites can overload servers, degrade performance, or cause system failures. One effective solution is to implement load balancing and failover methods. Load balancing divides the load across multiple servers to prevent overloading, while failover ensures the system stays functional by switching to backups in the event of a failure. This study aims to configure load balancing and failover on wireless networks using mikrotik devices and two internet modems. The test results showed that failover successfully maintained the connection when the main port was disabled, while load balancing increased internet speed by combining the main and backup networks.

Abstract

Children from Broken Homes are a vulnerable group often experiencing emotional disturbances due to family disharmony, such as divorce or prolonged conflict. The lack of public understanding regarding early psychological intervention for these children can worsen their mental condition. Therefore, an effective and easily understandable educational medium is needed to deliver information about Psychological First Aid (PFA). This study explores the use of motion graphic animation as an educational medium that presents PFA information in a visually engaging and communicative manner. The development process includes psychological concept research, storyboard creation, character design, and animation planning to the audience's characteristics. Evaluation results show that motion graphic animation can enhance the audience’s understanding of the importance of providing early psychological support to children from Broken Homes. The study concludes that motion graphic animation is an effective medium for conveying psychological education in a simple yet meaningful way and can serve as an alternative solution for public awareness and outreach. This data is seen from the results of testing with a questionnaire where from a total of 15 respondents, 40% or 6 people stated that they strongly agree. While 60% or 9 people stated that they agree and no one answered disagree or disagree.
