With the development of information technology, it has influenced various aspects of public services. Public service is an activity or series of activities in the context of service needs in accordance with statutory regulations for every citizen and resident for goods, services and/or administrative services provided by public service providers. At Class IIB Narcotics Prison Purwokerto services for registration of visits are still carried out manually, namely visitors are required to come first to the prison and register first. The service will be carried out by means of visitors registering with the administration and then choosing a schedule for the visit provided that the inmates visited also agree with the visit. This is not effective, so it is necessary to design a website?based application for visiting services so that public services are better for the community and more effective. And this application has its own name and logo as the identity of the application itself. With the final results achieved in designing this website?based application It is hoped that it will make it easier for users to make reservation visits and increase efficiency in public services for the better, especially at the Class IIB Narcotics Prison in Purwokerto.

IMPLEMENTASI KOMBINASI ALGORITMA MYSZKOWSKI TRANSPOSITION DAN VIGENERE CIPHER PADA KEAMANAN UNTUK FILE TEKS

Meylissa, Khairil, Juju Jumadi — Sat, 07 Oct 2023 00:00:00 +0000

Security and confidentiality issues are important aspects of data, messages and information. Myszkowski transposition work is done by compiling plaintext into matrix rows. Then the matrix is read per column so that the ciphertext is obtained. The number of columns used in the matrix is determined by the length of the key used. while the Vigenere Cipher works by reading word per character, where if the message sent exceeds the length of the key used, the key will be repeated again until the message sent gets its respective key. By combining the Myszkowski transposition algorithm and the Vigenere Cipher, it produces a method that can provide a better level of security compared to applying each method separately.
The results of the analysis and testing carried out using different decryption keys produced that the ciphertext could not be restored, which shows that this is normal because the method used is symmetric cryptography so that the decryption process can only be carried out using the same key as the key at the time of decryption.

Antika Sari, Toibah Umi Kalsum, Riska — Sat, 07 Oct 2023 00:00:00 +0000

For implement this high availability server, you can use special application software for clustering, such as heartbeat. This heartbeat is part of linux high availability project. Using heartbeat, you can do failover by promoting an active server to serve requests from clients and replace the function of the main server. This is done to ensure that the availability of existing data on the database server is always available when there is a request by the client. The purpose of this research is to build a database server that is always available by implementing a failover server and implementing data replication system on the database server. Database failover technology using heartbeats and using master to master replication system, data availability and system performance increase because the data has a backup. Failover database using heartbeats using master to master replication system has advantages (can do data backup automatically) and disadvantages (requires additional devices), so using this technology needs to be adjusted to the needs of system development.

Nelly Permatasari, Yessi Mardiana — Sat, 07 Oct 2023 00:00:00 +0000

The Blowfish algorithm is one of the existing encoding systems. Encoding aims to make a message more secure for its confidentiality. The blowfish algorithm is one of the modern cryptographic algorithms that uses symmetric keys in the encryption and decryption process. The application of the blowfish algorithm in this study is to secure text messages between the sender and recipient of the text message through a web?based application. Cryptography is the art and science of protecting data transmission by converting it into a certain code and is only intended for people who only have a key to change the code back which functions to maintain the confidentiality of data or messages. Applications for sending
messages using the blowfish algorithm are made using the PHP programming language and MySQL database. This web?based text message encoding application consists of several menus, including login menus, lists, incoming messages and sending messages. The web?based text message encoding application runs well according to each existing menu.
