Abstract

The aspect of data security has become a very important aspect of an information system. Many people start looking for ways to secure data or information, because global computing has become insecure and often escapes the attention of computer users and is starting to become a very serious issue. So, we need a way to secure confidential and important data. One of the cryptography methods that can be used is the RSA method. The RSA algorithm is one of the most popular public key algorithms used and is still used today. The strength of this algorithm lies in the exponential process, and factoring a number into 2 prime numbers which until now has taken a long time to factorize. The implementation of the system used the Visual Basic 2010 programming language and the method used in this research is an applied research method. Where the results of the tests that have been carried out are obtained where the RSA Algorithm can provide additional security to the document, this is because the text data owned by the user will be encrypted and replaced with a row of numbers that does not represent the contents of the original data.

Abstract

Android-based cryptographic applications using the rail fence cipher algorithm are made using the Java programming language (AndroidStudio), the PHP programming language (JSON File Web Service) and the MySQL database. This application has a url link for storing PHP files and message data in the database, while the url link is http://railfencecipher.my.id/. An Android-based cryptographic application using the rail fence cipher algorithm has been uploaded to Google Playstore by entering the rail keyword fence cipher. An android-based cryptographic application using the rail fence cipher algorithm can be used to assist communication between the two parties, both the sender and the recipient of the message. In addition, this application has implemented a rail fence cipher algorithm that is used to maintain the confidentiality of the message stored in the application's database. The records in the message body column in the database are in random form, therefore they cannot be read. This of course makes the application maintain the confidentiality of the messages sent, because there is a process of scrambling (encryption) of the message. Based on the results of the tests that have been carried out, the functionality of the android-based cryptographic application using the rail fence cipher algorithm runs well as expected and the message sent between the recipient and the sender is kept confidential because the message is encrypted.

Abstract

Bandwidth management is necessary to ensure that the available bandwidth is allocated according to the needs of each connected user. One method that can stabilize the allocation of bandwidth is the Hierarchical Token Bucket (HTB) method. The purpose of this research is to regulate the amount of bandwidth to meet the internet usage requirements for each user without allowing any single user to dominate the bandwidth usage on the internet network. The research was conducted in five stages: problem analysis, data collection, design and implementation of HTB, HTB implementation, and analysis of the final results of the system using HTB. Problem analysis and data collection were obtained through direct observation. The design and implementation were carried out using the HTB method on MikroTik routers. The HTB method allows us to create queues in a more structured manner by performing hierarchical groupings. Testing results show that the HTB method can manage bandwidth usage for each user when using the internet simultaneously. The analysis of the application of the HTB method at PT. GSB indicates that each user receives bandwidth based on limit-at and priority.

Abstract

The tracer study is one of the essential activities carried out by universities to monitor the success of their graduates in the workforce as well as to serve as an evaluation tool for improving the quality of education. However, the alumni tracking process that is conducted manually often encounters various obstacles, such as difficulties in data searching, information duplication, and delays in reporting. Based on these problems, this study aims to develop an alumni tracking application for Universitas Dehasen Bengkulu by implementing the Brute Force algorithm as a method for searching alumni data based on specific keywords. The implementation results show that the system can display alumni search results quickly and accurately by providing information on the number of string comparisons, execution time, and match percentage. In addition, the application also provides features for alumni data management, alumni questionnaire input, and job information updates, which support the digital implementation of tracer study activities. Thus, the application of the Brute Force algorithm in this system has proven to be effective in assisting the alumni data search process and improving the efficiency and accuracy of graduate tracking at Universitas Dehasen Bengkulu.
