Optimization of data security techniques is very necessary so that the data or information that is secured is really safe from attack. Data that has been encrypted based on cryptographic techniques very quickly raises suspicion that the data is confidential or important. Therefore, this technique is better combined with steganography techniques. Utilization of steganography techniques can minimize the attacker's suspicion of data that is secured, because by using steganography data techniques can be hidden on certain objects. This study discusses how to encode a text based on the Merkle-Hellman Knapsack algorithm and the resulting password is hidden in a grayscale digital image as a hiding object based on the pixel value differencing algorithm. This is done to minimize suspicion and make it difficult for attackers to find out confidential or important data.Keywords: cryptography,steganography, merkle-hellmankanpsack, PVD, image

Published: January 2020

The size of the audio file can affect the time of sending data to be long and can cause waste of storage space. Therefore, compression is performed to compress the contents of the audio file into smaller ones. One of the compression techniques is lossless technique, which is a compression method where the compressed audio file can be returned to the file before it is compressed without losing information on the previous data. This study uses the Interpolative coding algorithm on mp3 audio files. Interpolative coding algorithm is an innovative way to assign dynamic code to data symbols. This method is different from other compression methods, because the code it provides for individual symbols is not static. The design of this system consists of 2 main processes namely the compression process and the decompression process and the process of calculating the performance of Compression Ratio (CR) and Redundancy. The resulting compression results in a new file with the * .ipc extension containing the compressed bit string which can then be decompressed. Application designed only one form, where in the form there is a process for compression and decompression, while the process of compressing the input file has the extension *. MP3 and produces output with the extension * IPC, and the size of the compressed audio file is smaller than the previous file size .Keywords: Compression, Audio File, Interpolative coding algorithm

Grand Sirao Hotel is a hotel that stands in the middle of Medan City, located on Jl. Semarang. Grand Sirao Hotel is an attractive hotel in the sector of cooperation in certain fields, but in this hotel it often happens in cooperation with outside companies. One of the problems that often occurs at the Grand Sirao Hotel is the constrained stock of goods needed for guests staying at the hotel, items that are often constrained which are usually in the form of sandals and toiletries that are in short supply. This problem often arises because of the many other factors between companies related to hotel owners themselves, debates that often arise from hotel owner claims include quality of goods that are sometimes incompatible with reservations and need to be taken into account, inventory can be exhausted, prices always go up because of skyrocketing market prices and other problems. This collaboration problem arises due to lack of success in determining partnerships with related companies that are not appropriate and in company selection is also still manual and there are appropriate systems and criteria. Therefore a decision support system is needed in the selection of partners upon the proposed approval. One solution to this problem that is right is to make a decision system in the decision of the company's business partners so that the determination of cooperation in accordance with the right requirements. By using a Decision Support System (SPK) is expected to help the company in making decisions made by the right company partners in increasing the efficiency of the decision. PSI (Index Selection Preference Method) is a method for solving multi-decision making (MCDM) decisions. In the proposed method it is not necessary to submit among the attributes. There are no attributes required in computing that are involved in decision making. It is hoped that by using the PSI (Index Selection Preference) Method, it is necessary to establish a decision support system which can assist in the selection of corporate cooperation partners at the Grand Sirao Hotel.Keywords: Determination of Cooperation Partners, Decision Support System, PSI (Index Selection Preference)

In this study, the authors used a decision support system with the Promethee II method to find the value of weights and criteria, and to find the final score or to find the finalist ranking of the North Sumatra Language Ambassador. Thus the Decision Support System is needed in order to help the North Sumatra Language Office in determining the Finalists of the North Sumatra Language Ambassador. To overcome these problems, it is necessary to build a decision support system application for the selection of North Sumatra Language Ambassador Finalists using the Promethee II method so that it can help and facilitate the North Sumatra Language Hall in making a decision to choose the North Sumatra Language Ambassador and the resulting decision is satisfactory.Keywords: Decision Support System, Language Ambassadors, Promethee Method ii

Many hot medicine products are marketed to the public. Because many products are marketed, making people confused in choosing the best hot medicine in the best. Hot medicine in the most popular community means that the drug is the best medicine for the community. In this research, there are two main problems in the research that can be formulated, namely whether the use of the AHP method can make the decision to determine the heat medication in the most popular community and how to look for a hot medicine decision in the most popular community. Analytic Hierarchy Process (AHP) method is used to find the ratio scale, both from discrete and continuous pair comparisons. AHP decomposes complex multi-factor or multi-criteria problems into a hierarchy. Hierarchy is defined as a representation of a complex problem in a multi-level structure where the first level is the goal, followed by the level of factors, criteria, sub-criteria, and so on down to the last level of alternatives.Keywords: Decision Support System, Analytic Hierarchy Process Method, Internal Medicine

The base language is one of the regional languages used in Aceh Province, precisely in Southeast Aceh. The base language is basically divided into 3 (three) pieces of dialeg, namely upstream (subtle), middle (medium), and downstream (rough). As time goes on, the Alas language becomes increasingly forgotten because the younger generation prefers to learn foreign languages to keep up with the times so that many Alas communities, especially the younger generation, cannot communicate using the Alas language. To preserve the Alas language, a technology-based dictionary application is needed that is developing at this time to help young people learn the Alas language. Improving the accuracy of string matching in translating the Alas language into Indonesian in the application in the dictionary application used to study the Alas language in this study used the Turbo Boyer Moore string matching agorithm. The results of this study are in the form of desktop-based applications that can be used easily on a computer with the results of Indonesian language translation search into the Alas language with accurate stringency accuracy efficiently and efficiently with minimum time. Keywords : Regional Language, Alas-Indonesian Indonesian Dictionary, String Matching, Turbo Boyer Moore.

The word fashion is synonymous with fashion, in today's digital era fashion has become a lifestyle that can introduce personality through fashion on social media. In the term fashion, there are many terms that form the basis of knowledge to match one's fashion. The term fashion is generally studied using foreign languages so that many ordinary people find it difficult to understand in more detail related to fashion terms so that there is a need for applications that adopt science related to the term fashion. An application that was built with the main objective to search for information such as fashion terms is inseparable from the existence of string matching. String matching can be interpreted as an activity that works to match something that is sought in a container with the contents stored in the container. Algortima string matching which is implemented to search for the meaning of the term fashion in this study is the Horspool algorithm. The horspool algorithm is a boyer-moore derivative algorithm, to go through the process when there is a mismatch of character patterns with text characters, the horspool algorithm uses bad-matches repeatedly until all the character patterns are found to have a match against the text. The results of the application built in this study can facilitate ordinary people who have difficulty finding information related to fashion terms more easily.Keywords: Implementation, Fashion Terms, Algorithms, Horspool
