Abstract

Decision support system is a computer-based system that functions for decision making by utilizing data and models to solve unstructured and semi-structured problems within a company or organization. Deli Medan Hospital is one hospital that offers quality health services accompanied by competitive prices. The price offered by Deli Medan Hospital is in accordance with the quality of delivery provided so that the use of this hospital's health services is always a satisfaction. this can be seen from the number of patients who are still increasing every year Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is one of the multicriteria decision making methods first introduced by Yoon and Hwang (1981). TOPSIS uses the principle that the chosen alternative must have the closest distance from the positive ideal solution and the farthest from the negative ideal solution from a geometric point of view using Euclidean distance to determine the relative proximity of an alternative to the optimal solution. Positive ideal solutions are defined as the sum of all the best values that can be achieved for each attribute, while the negative-ideal solution consists of all the worst values achieved for each attribute

Abstract

SMS (Short Message Service) is a popular communication technology revolution. The development of computerized technology has been very advanced. SMS is very vulnerable to data theft or theft by irresponsible parties. For the sake of maintaining the security of SMS can be done by using cryptographic techniques. Cryptographic techniques can encode text messages by encrypting them into passwords that are not understood. Mars algorithm is an algorithm that uses a 128-bit key and the encryption process consists of 32 rounds. This symmetry algorithm will produce a higher level of security for the ultrasound image because it can encode it into a form of cipher with a process that is complex enough so that it will be difficult for cryptanalysts to access the image. This research will use the Mars algorithm for the encryption and decryption process, so the process needs to go through several long stages in order to produce the final cipher. This study describes the process of securing SMS by encoding it based on the Mars algorithm, in the form of a password that is difficult for others to understand and understand. This is done as an effort to minimize acts of misuse of SMS

Abstract

Text file size is sometimes relatively large where the better the quality of the resulting text file, the larger the file size needed to store the text file. With a very large text file size, when carrying out the transfer process the transfer process may fail because the media storage space exceeds the limit. The solution to this problem is how the text file can be compressed in order to speed up the transfer and storage of text files. Compression in text files is done by reducing the size of the text file by reducing the bits in the text file, but not eliminating the information data in it.By compressing, large data will be reduced in size so as to save storage space. In this study, the algorithm used is punctured elias codes, by using this algorithm, the compression results of the values have different results for each value, and the compression results will be beneficial in sending, and moving text files will be easier.

Abstract

The Smart Indonesia Card is the provision of educational cash assistance to children aged 6-21 years or who come from underprivileged families with the aim of continuing their education. Yapim Taruna Medan High School is one of the private schools in the city of Medan. This school provides Smart Indonesia Card scholarship assistance (KIP) where KIP scholarships are intended for underprivileged students and the number of KIP recipients is also limited based on the quota given, which is faced by the Yapim Taruna Medan High School in determining who is who. those who get KIP scholarships are less objective and transparent. Many students whose parents have a very difficult economy do not get KIP scholarships while some students who get KIP scholarships have parents who are above the economy who do not get the scholarship. So that to overcome this problem a Decision Support System for Recommendations for Accepting Indonesian Smart Card assistance is needed by applying the MAUT Method and Weighting Using the ROC Method at the Medan Yapim Taruna School.
