Abstract

Bilinear interpolation is a method that is widely used in image scaling where bilinear interpolation can be applied to upscaling and downscaling processes. Several previous researches have shown that bilinear interpolation provides low quality reconstruction results compared to other scaling methods but is still a good alternative considering the lower process complexity compared to other scaling methods. For this reason, a mechanism or model is needed that can be juxtaposed with bilinear interpolation scaling so that the reconstruction results have better quality. Referring to previous research, neural networks can be used in the reconstruction process where artificial neural networks are used to learn features or information that is lost during the downscaling process so that it can be reused during the reconstruction or upscaling process. This research applies inverse backpropagation to help improve the quality of image reconstruction results on bilinear interpolation. The test results show a much better MSE value of up to 40.25% compared to reconstruction using ordinary bilinear interpolation. Meanwhile, the increase in PSNR obtained ranged from 0.4% - 9.7%.

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.

Abstract

University of Harapan Medan is one of the private tertiary institutions in North Sumatra which has an informatics engineering study program. The informatics engineering study program is a study program that has many enthusiasts. Every year this study program graduates more than 200 students. To produce graduates who have potential, reliability and competence in the field of technology and information, it is necessary to make a selection at the beginning, namely at the time of admission of new students. There are 5 criteria used in the selection process, including the average report card score, basic ability test, computer ability test, psychological test, and interview. Each criterion has 5 weights of values, namely very high, high, medium, low and very low.  The selection process for admission of new informatics engineering students with a decision support system for the EDAS (Evaluation Based On Distance From Average Solution) method.  Where the stages in this method are by normalizing the decision matrix and looking for the average from alternatives, then from these results calculate the average positive distance (PDA) and negative distance (NDA) as well as the assessment of the weighted attribute weights of SPi and SNi, after that the normalization of positive and negative distance weights is carried out for determining the ranking score. From the results of the analysis carried out using the EDAS method, with a sample of 10 prospective students it was concluded that the 6th order student candidate had the highest score with a score of 0.519 and the lowest score in the 7th order student with a score of 0.14. Therefore, the level of accuracy of the EDAS method in selecting new student admissions is around 20%. Of course, this accuracy value will change with large data samples.

Abstract

House is one of the most basic human needs where house is a place for shelter and ongoing activities as well as an investment. Selection of houses needs to be done in order to get the best alternative houses that match the criteria of prospective buyers, selection of houses based on many aspects such as price, land area, house space, public services, environment, location, road access, facilities and other aspects. Therefore, in this study, a web-based decision support system application was built to decide the best house based on decided aspects. The decision support system was built using the SMART (Simple Multi Attribute Rating Technique) method. This method has a working method based on the theory that each alternative consists of several criteria that contain a number of sub-criteria that have a value and each criterion has a weight to describe how important its value is compared to other criteria. The results obtained in this study are the obtaining of the best house alternative based on the criteria and weight values that have been determined by the user using a decision support system that has been built. Keywords: House, Decision Support System, SMART, Web, Criteria
