Abstract

The development of computer technology nowadays has progressed very rapidly in line with the development of computer and telecommunication technology, making communication more open and information exchange faster, however not all developments in communication technology have had a positive and beneficial impact. One of the negative impacts of technological development is the existence of wiretapping, with the presence of encrypted tapping, the security aspect in exchanging important information. The problem of sending messages (e-mail), be its agencies, education, government, private and others, must contain confidential information, so encryption of the message is required. Encryption of information is important to support information security, because it can guarantee message security. Therefore, encryption is needed by users who have information that is guaranteed its confidentiality. One way to store data sent via email is to use cryptography. The Affine Cipher is an extension of the Caesar Cipher which multiplies the plaintext by a value and adds a shift. Creating an application by implementing cryptography using the Affine Cipher is one way of maintaining the confidentiality of information and is very important. The results obtained from this research are that the application created can change the content of existing messages and can store information that is available when sending e-mails. The process of encoding messages using the Affine Cipher algorithm is successfully used to hide secret messages into text.

Abstract

AbstractThis program aims to enhance the digital literacy of students at Pondok Pesantren Saifullah An-Nadliyah Namorambe through computer training. The training covers basic computer skills, word processing software, internet use, and ethical social media practices. The method used includes hands-on training and practice, with skills assessment before and after the sessions. The results show that the students have become more proficient in using computers, searching for information, and using social media responsibly. The program also sparked an increased interest in technology among the students. However, challenges such as limited computers, unstable internet access, and a lack of qualified IT instructors remain. Ongoing support from the pesantren, donors, and the local government is crucial. Overall, the program has a positive impact by preparing students for the digital era. Additionally, the program aims to strengthen the institution's international reputation and expand collaboration with foreign institutions. The two-day training in collaboration with Politeknik Sultanah Bahiyah Malaysia (PTSB) is expected to enhance the students' computer skills and establish computer studies as a mandatory subject at the modern pesantren..
