Abstract

The development of science and technology along with the times can support all processes and activities carried out by humans. A computer is a sophisticated tool or electronic object that is broadly composed of hardware and software that work together in processing data that input or by the user. Computers have a lot of features, namely being able to process data in the form of numbers, letters, sounds, symbols, and others. With the existence of computer technology, data processing will be easier and more efficient so that users do not need a long time to manage data. The Information Systems Study Program, Computer Science Faculty, University of Dehasen Bengkulu, is still not effective and efficient in campus services for students who wish to submit their final assignment, especially when submitting thesis titles because they still use the manual method. The study program files are recapitulated one by one into Microsoft Excel, so there is a high risk of data input errors due to human error, not to mention the possibility of duplicate titles that can occur, where the title that has been submitted can be submitted again by another student. This process needs to be supported by the implementation of technology, namely using web as an implementing medium. The writer used PHP programming language and MYSQL database which aims to build an information system for submitting thesis titles which is expected to support and facilitate the process of submitting thesis titles and easily obtain information about campus services, especially when submitting thesis at University of Dehasen Bengkulu.

Abstract

The application of Wazuh to monitor network security systems at SMK Negeri 1 Bengkulu City can help network operators monitor security systems, computers and make it easier to control the devices being monitored, so that they can take action as soon as possible if there is a disruption to the system and network based on the monitoring results. Wazuh can monitor files in the directory folder. The information provided is in the form of adding, modifying and deleting files contained in the directory folder. Based on the tests carried out, the results showed that the application of Wazuh to monitor the network security system at SMK Negeri 1 Bengkulu City was running well and could help network administrators by providing information related to the agent device being monitored.

Abstract

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

Abstract

The network at SMK Negeri 5 Bengkulu City at this time often has complaints such as a decrease in internet network performance which in turn affects all computers connected to the network. Intrusion Detection System (IDS) whose job is to monitor networks and suspicious activities in a network system. The research method that the authors use is a linear sequential process model. The life cycle of implementing a network system is defined in a number of phases, namely: Problem Identification and Formulation, Literature Study, Testing, Implementation, System Design, System Requirements Analysis. The author uses Snort, Telegram Bot on Ubuntu based IDS sensor engine. The results of this thesis research conclude that the applied IDS system can function to detect intruders or intruders on the IDS sensor machine, which is displayed in the form of notifications to telegrams.

Abstract

This research is entitled Design and Implementation of Network Security System Using Network Management System (NMS) and Firewall at SMA N 1 Bengkulu City. Aims to build a computer network system using linux ubuntu server by setting squid and webmin as a graphical user interface (GUI). Where in doing network management Squid works well including being able to limit accessible website addresses, IP Address management of network users and ports that can or cannot be accessed. The GUI is being used by webmin, because the webmin interface is easy to use. In limiting website addresses, network users' IP addresses and ports that cannot be accessed are done manually via Squid. Linux operating system ubuntu server 20.04 is very good in running Network Management System (NMS) and Firewall because it can be installed or added other tools such as squid and webmin, linux ubuntu server 20.04 in running Network Management System (NMS) and Firewall does not require resources great hardware.

Abstract

The document file security application at the Bengkulu City Education Office was made using the Visual Basic .Net programming language. In this application, 2 cryptographic algorithms have been implemented that can be used to secure document files, especially the employee payroll list file, namely the DES algorithm and the AES algorithm. In addition, this application has also embedded a process to analyze the comparison of the DES and AES algorithms, so that it can be known which algorithm is better to use. The comparison aspect consists of 2 aspects, namely processing time and file size after processing. Based on the tests that have been carried out, it can be concluded that the document file security application at the Bengkulu City Education Office is capable of carrying out the process of encrypting and decrypting document files and the functionality of the application has run as expected. From the test data that has been carried out by the encryption and decryption process, the results obtained based on the encryption processing time show that the AES algorithm is faster than the DES algorithm, based on the decryption processing time it is found that the AES algorithm is faster than the DES algorithm, based on the file size after the encryption process it is found that the DES algorithm and the AES algorithm have the same file size, based on the file size after the decryption process it is found that the DES algorithm and the AES algorithm have the same file size
