<![CDATA[A data transmission security system (secure data communication) is installed to prevent theft, damage, and misuse of data sent via computer networks. In practice, data theft takes the form of reading by unauthorized parties usually by tapping public channels. Computer network technology has been able to reduce and even eliminate the possibility of data damage due to poor physical connectivity, but interference can still occur because there is an element of intent that leads to misuse of the system from certain parties. This cryptosystem is an algorithm that provides a fairly high security which is not based on the secrecy of the algorithm (restricted algorithm), but is more emphasized on the security/confidentiality of the key used (modern cryptographic algorithms). The restricted algorithm is usually used by a group of people to exchange messages with each other, they create an encryption algorithm that is only known to members of that group, so that every time a group member leaves, the restricted algorithm must be replaced because of the possibility that group members who leave the group can leaking the algorithm. So every time a group member leaves, the algorithm used does not need to be changed, but only changes the key. Therefore, the author tries to use the Massey-Omura Algorithm whose implementation uses the ThreePass Protocol to generate prime numbers because the Massey-Omura algorithm is one of the asymmetric algorithms that factorizes large numbers to get the private key]]>

<![CDATA[The bell is certainly no stranger to the world of education. In general, the bell still uses human power to ring it. It is still rare in the world of education to use an automatic bell that can work alone according to the specified time in the teaching and learning process. The purpose of designing the automatic bell at STIKOM Tunas Bangsa Pematangsiantar is to simplify the work of picket officers and optimize the right time for the teaching and learning process. The work process of this tool is to input the predetermined class hours into the Arduino Uno Microcontroller using the C language in the Arduino IDE Software. After that the Microcontroller will read the schedule program for lessons that have been input into the Microcontroller. If the input program matches today's class time schedule, the bell will automatically issue the output in the form of an information notification sound. This tool also has a 16x2 Keypad Shield for manual setting in a matched test mode within the current exam time and automatically generates a notification sound output, where this automatic buzzer is fully controlled by the Arduino Uno Microcontroller command and the timing that has been set in the RTC ( Real Time Clock) as a time saver]]>

<![CDATA[Data mining is a term used to describe the discovery of knowledge in databases. Data mining is a process that uses statistical, mathematical, artificial intelligence, and machine learning techniques to extract and identify useful information and related knowledge from large databases. With data mining, a gem in the form of knowledge will be obtained in a large number of data sets. The Apriori (RF) method is a method that can improve accuracy results, because generating child nodes for each node is done randomly. This method is used to build a decision tree consisting of root nodes, internal nodes, and leaf nodes by taking attributes and data randomly according to the applicable provisions. The root node is the node located at the top, or commonly referred to as the root of the decision tree. The solution for determining chemical stock inventories at the Medan Branch Forensic Laboratory, by applying the Apriori method to determine the correlation coefficient level of frequently used products so that more frequently needed products can be provided to avoid chemical vacancies at the Medan Branch Forensic Laboratory]]>

<![CDATA[Currently the use of information technology as a medium of information exchange is growing very widely. Various types of information such as text, images, sound and video can be converted into digital media that allows it to be reproduced or transmitted through various media. One of them is the internet, through the internet we can easily exchange information with other people in various places. However, there are times when information/messages are confidential, where no other party may know the contents of this information other than the sender and recipient. So we need a security against the message. Cryptography is a technique and art to encode messages or information in a medium, such as text, images, audio or video which aims to avoid suspicion from unauthorized people. For that we need a software that can encode confidential information in a text file. However, in hiding messages in text files using cryptography alone is not necessarily safe, so a useful algorithm is needed to improve security, therefore Cipher Block Chaining and Triangle Chain Cipher algorithms are needed. The research objective is to apply the Cipher Block Chaining and Triangle Chain Cipher algorithms for text file encoding applications. This is necessary because it often happens that the text message sent is a secret message that should not be known to just anyone. Block Chaining Ciphers and Triangle Chain Ciphers are useful algorithms to provide an advantage in terms of increased security in text files.]]>

<![CDATA[As technology develops, the process of sending files no longer needs to be done manually. Data or files can be sent electronically via email. The image file size is sometimes very large, where the better the quality of the resulting image, the bigger the pixel size needed to record the image. With a very large image file size, the transfer process may fail, because the media storage space exceeds its limit. The solution to this problem is how the image file can be compressed in order to speed up the transfer and storage of image files. Image compression is done by reducing the size of the image file by reducing the bits in the image 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 the Swiss army knife data compression, using this method, the compression results from the value of k have different compression results for each value, and the compression results will be beneficial in sending and moving image files more easily]]>
