<![CDATA[Every year, students are required to complete a final project in the form of a thesis as one of the graduation requirements. However, in determining a thesis title that is relevant to the chosen scientific field, students often experience difficulties. The number of thesis titles available in libraries and websites can confuse students in choosing the right title. One method that can be used to achieve this goal is the Turbo Boyer-Moore pattern search method. Turbo Boyer-Moore is one of the efficient pattern matching algorithms to search for certain words or phrases in text. From the results of the tests carried out, it can be concluded that the implementation of the designed program in searching and detecting the same title with a similarity percentage.]]>

<![CDATA[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.]]>

<![CDATA[Implementation of snort as a wireless network security detection tool using linux ubuntu by adding a server that is used to observe activities on a wireless network, if there is an activity that is considered dangerous by the client, the information will be stored in the snort log and database. The web-based front-end uses BASE (Basic Analysis and Security Engine) which can be accessed through a browser with the url : IPaddressServer/base/. The information provided is related to attacks detected by snort that have been stored in the database. The information is in the form of source and destination IP addresses, the type of attack that occurred. Based on the tests carried out, it was found that the implementation of snort as a wireless network security detection tool using linux ubuntu can help detect attacks that occur on the network and provide information related to these attacks.]]>

<![CDATA[One system that can monitor computer networks is using spicework. Spiceworks monitors based on the ip address of the computer connected to the network, spicework in monitoring the network requires high hardware specifications of at least 4GB memory. A system that can monitor the network does not yet exist on the SMK N 1 Bengkulu City network, the computer network at SMK N 1 Bengkulu City is used by students, teachers and TU, libraries and for other purposes, in addition to knowing whether or not the computer is connected to the SMK N 1 Bengkulu City computer network, it can also be used to monitor the resources (hard disk and memory) of the device. In doing so.]]>

<![CDATA[The issue of data security and confidentiality is one of the important aspects of data, messages and information. Stream Cipher is often referred to as a stream cipher. The advantage of this method is that it is relatively faster in the encryption-decryption process and is also not limited by the length of the plaintext. ROT13 is a substitution cipher encryption by shifting characters forward 13 times, counting 1 character in front of it, and shifting characters based on the order of characters in the ASCII table. By combining the Stream Cipher and ROT13 algorithms, it produces a method that can provide a better level of security compared to the application of each of these methods separately. The results of the analysis and testing carried out using different decryption keys resulted in the ciphertext cannot be returned which shows normal things because the method used is symmetrical cryptography so that the decryption process can only be done using the same key as the key during decryption.]]>

<![CDATA[One of the most widely used data storage in databases today is using MySQL. MySQL is able to store many data items in it, even up to millions of items. So with so much data in this database, it is very necessary to replicate data to maintain data safety and security. Linux ubuntu server 18.04 is an open source operating system, this operating system is very well used as a server because it does not require high hardware specifications and can also be obtained for free because it is open source. The replication technique is very well applied to the Bengkulu Province Communication and Information Service, this is because the Bengkulu Province Communication and Information Service holds a lot of data. Both internal data and external data. In communicating data to the database using the replication technique, it is very fast with a time of +/- 3 seconds of data communication, this time will also be affected by the condition of the computer network and the device used. The replication technique is very good for agencies that have a very large database and require a long storage time.]]>

<![CDATA[Implementation of Security Information Event Management (SIEM) for Network Monitoring at SMA Muhammadiyah Boarding School can help network administrators know the activity and status of devices connected to the network whether UP or Down, can help provide information in the form of logs of services that run and log security events on each device connected to the network. This of course can make it easier for network administrators to deal with problems found on network devices connected to OSSIM AlienVault. In OSSIM AlienVault there is a web UI platform that can make it easier for network administrators to monitor the network at SMA Muhammadiyah Boarding School. Where the OSSIM AlienVault Web UI can be accessed via the IP Address Server in the browser. Based on the tests carried out, the results show that the Implementation of Security Information Event Management (SIEM) for Network Monitoring at SMA Muhammadiyah Boarding School runs well and can help network administrators in network monitoring and can provide information in the form of event logs on each device connected to the network.]]>

<![CDATA[Bandwidth management is needed therefore the existing bandwidth is divided according to the needs of each connected connection. One method that can stabilize the distribution of bandwidth is the Hierarchical Token Bucket (HTB) method. This study aims to adjust the amount of bandwidth to suit the needs of internet usage for each user without making one user dominate the use of bandwidth on the internet network. The research was conducted in 5 stages, namely: problem analysis, data collection, HTB design and implementation, HTB implementation and analysis of the final results of the system with HTB. Problem analysis and data collection are obtained through direct observation and observation. Design and implementation are done with the HTB method on the proxy router. The HTB method allows us to make the queue more structured, by doing multilevel groupings. The test results show that the HTB method can manage bandwidth usage for each user when using the internet simultaneously. From the analysis of the application of the HTB method in the computer laboratory of engineering faculty in Universitas Muhammadiyah Bengkulu, it shows that loyal users get bandwidth based on their limit-at and priority, which is equal to]]>
