Seeing the rapid development of science and technology in today's world requires us to keep up with the development of science and technology. Especially in the field of informatics technology such as computers and websites, computers are the most advanced technological development media that are widely used by the general public for processing data with supporting software contained in the computer itself. In this era of globalization, the progress of information technology is very rapid, we can find information easily by utilizing internet facilities. The website is one of the clear evidence of the development of computer technology, where the website is a service that can be accessed by any media. Kerawan Trade Village is a village located in Tanjung Morawa sub-district, Deli Serdang district, North Sumatra province, where in the Kerawan trade village there are several hamlets in it. Many activities are carried out by the people who live in the Kerawan trade village such as youth organizations, UKM activities or products and handicrafts produced by the local community. Every activity, product or handicraft produced should be published to the general public in order to increase the selling value of the Kerawan Trading Village or the sale of products or crafts. Kerawan trading village apparatus has planned the development of rural areas as one of the foundations for village economic growth in the long term by relying on the resources available in the village, one of which is the existence of Village Owned Enterprises (BUMDes). So we need a media called the village website as a place or promotional media about all forms of activities carried out by people who live in the Kerawan trade village. The village website is an online-based portal or site in which there is public information about village activities, both in terms of administrative, social, cultural, institutional and other information related to the village. The implementation team has succeeded in creating and also building a Website for Desa Dagang Kerawan. Village officials and also the people of Dagang Kerawan Village have a website as a medium for promoting activities, products and also crafts produced by the local community. Village officials and also the people of Dagang Kerawan Village can manage and understand the benefits of the website.

Abstract

File size or large files are not only a problem in terms of storage, but also another problem when communication between computers. Data usage with a larger size will take longer transfer times compared to data that has a smaller size. Therefore to overcome this problem you can use data compression. Seeing the compression of data compression, data compression is needed that can reduce the size of the data, so that it gains the advantage of reducing the use of external storage media space, accelerating the process of transferring data between storage media, data utilization used in this study is the elias delta codes algorithm. Compression is a method used to reduce the bit or data from the original result to a new result. Where this compression will be applied into the algorithm, the elias delta codes algorithm. After getting the results of the compression it will be designed into Microsoft Visual Studio 2008

Abstract

In the process of managing multiple images or images, with larger image sizes or images that can hold longer storage and larger storage, it is needed more often as it cannot be contained on storage media and is not conveyed, thus opening up free space in memory storage media. So to make a lot of free space and have a data size that is not large on the storage media, a compression method is needed which means to shorten the required bit size. Punctured Elias Algorithm Code can be used to obtain information about the compression performed by compressing images to provide benefits in storage and requires more memory space compared to uncompressed images.

Abstract

The MySQL database system is one of the database systems that is widely used in the world, both for personal and corporate purposes. However, the increasing number of cyber attacks occurring on database systems makes it increasingly important to secure data security in database systems. Cyber attacks can be via SQL Injection or hacking via connection commands to the database using the application whose database you want to hack. This is the focus of the problem, so it is necessary to secure connections to the database using cryptographic algorithms. This research aims to improve the security of the MySQL database system by implementing the Caesar Cipher cryptography technique and the Stout Codes compression technique in connection commands to the database via a client application built using the Visual Basic programming language. The testing method used in this research is experimental, where the MySQL database system is tested using ordinary connection commands and connection commands that have been encrypted with the Caesar Cipher algorithm and the Stout Sodes algorithm. The test results show that the use of the Caesar Cipher and Stout Codes crypto-compression systems can increase the security of the MySQL database system by making access difficult for unauthorized parties with a success percentage of 100%. Thus, it is hoped that this research can contribute to improving the security of the MySQL database system which is currently increasingly vulnerable to cyber attacks

Abstract

The ease of accessing the internet makes it very easy for humans to share various kinds of files. These files are very easy to download, so it is not uncommon for these files to become duplicates or the same files are stored on personal storage media. This of course will take up personal storage space owned. To avoid this, the steps that can be taken are to provide the identity of each file that represents the contents of the file. So that it can be known whether the contents of the file are the same or not. To generate the identity of a file, a special algorithm is needed that can represent the contents of the file. Algorithms that can be used to generate file identities are algorithms that fall into the hash function category. But in its development there are many algorithms in hash functions that can be used to generate file identities. The algorithms that are often used are the MD5 algorithm and the SHA-256 algorithm. The MD5 and SHA-256 algorithms have different algorithm structures so they have different performance when generating the identity of a file. By comparing the performance between the MD5 and SHA-256 algorithms, we will get an algorithm that has better performance when used to generate file identities.

Abstract

Perkembangan teknologi digital meningkatkan kebutuhan untuk melindungi data. Algoritma kriptografi seperti Caesar Cipher menjadi solusi, namun Caesar Cipher klasik rentan terhadap serangan brute force. Penelitian ini memodifikasi Caesar Cipher dengan menggabungkannya dengan algoritma pembangkit bilangan acak Linear Congruent Method (LCM). Modifikasi ini meningkatkan keamanan dengan menambahkan proses enkripsi Caesar Cipher dua lapis. Lapis pertama menggunakan Caesar Cipher konvensional dan lapis kedua menggunakan Caesar Cipher dengan kunci yang dihasilkan oleh LCM. Hasil penelitian menunjukkan bahwa Caesar Cipher yang dimodifikasi dengan LCM lebih aman dibandingkan Caesar Cipher konvensional. Modifikasi ini meningkatkan kompleksitas proses dekripsi dan membuat serangan brute force menjadi lebih sulit.
