Abstract

Keamanan merupakan hal yang vital dalam segala aspek untuk menjaga informasi. Pada komputer atau laptop, pesan teks merupakan salah satu data penting yang perlu dilindungi oleh sistem keamanan data. Pada perangkat komputer atau laptop, keamanan data digunakan untuk menjaga keamanan data penting kita. data pribadi. Enkripsi digunakan untuk mencegah pihak yang tidak diundang membaca pesan. Selama proses deskripsi sedang digunakan, pesan dapat dibaca ulang oleh penerima yang dituju. Tingkat keamanan informasi pesan dapat ditingkatkan dengan mengenkripsi pesan teks. caesar cipher adalah metode untuk enkripsi yang membutuhkan sedikit usaha. Perangkat lunak Visual Basic 2010 mencakup implementasi algoritma Caesar Cipher. Deskripsi pesan dan desain aplikasi keamanan enkripsi hanya dapat digunakan pada komputer. Dengan mengubah pesan asli menjadi pesan rahasia melalui pergeseran kunci, penelitian ini telah memungkinkan pesan untuk dijaga.

Abstract

The Food Security and Horticulture Office of North Sumatra faces challenges in the management of Service Travel Letters (SPD), such as submitting letters, making letter notes, operational costs, which are still done manually using manual methods, so it is time consuming. This hampers the effectiveness of document management and data-based decision making. To overcome these problems, this research develops a web-based monitoring information system. This system is designed to manage official travel letters, to minimize the time and recording of letter reports. With the web-based Monitoring Information System, the management of official travel letters becomes more structured and can be accessed in real-time, thus increasing efficiency in carrying out official duties in various regions of North Sumatra. This research uses the Research and Development (R&D) method with stages including needs analysis, system design, prototype development, testing, and evaluation. The results of the system implementation show that the use of this Monitoring Information System is able to speed up the process of submitting and approving official travel letters, as well as reducing errors in data collection and recording of trips.
