Abstract

Keamanan data dalam aplikasi Android menjadi perhatian penting, terutama dalam melindungi informasi sensitif dari akses yang tidak sah. Algoritma Blowfish merupakan salah satu metode enkripsi simetris yang terkenal karena kecepatannya dan fleksibilitas panjang kunci. Dalam penelitian ini, kami mengimplementasikan algoritma Blowfish dengan kombinasi Android ID untuk mengikat enkripsi pada perangkat tertentu. Android ID digunakan sebagai bagian dari kunci enkripsi agar data yang terenkripsi hanya dapat didekripsi oleh perangkat yang sama. Implementasi dilakukan dalam lingkungan pengembangan Android menggunakan bahasa pemrograman Java/Kotlin dan pustaka kriptografi Java Cryptography Extension (JCE). Hasil pengujian menunjukkan bahwa metode ini mampu meningkatkan keamanan dengan memastikan bahwa data tidak dapat diakses di perangkat lain meskipun file terenkripsi diekstrak. Penelitian ini memberikan solusi efektif untuk meningkatkan proteksi data pada aplikasi Android dengan mempertahankan performa sistem yang optimal.Kata Kunci: Blowfish, Android ID, Enkripsi, Kriptografi, Keamanan

Abstract

Kedai Wildan is  a  restaurant that is  often visited. Not  a  few restaurants are overwhelmed to serve customers when it's busy. Customers also feel uncomfortable if the service in the wildan stall is not optimal. One of the problems is the menu ordering system which still uses the manual method and customers must come to the location to be able to order the existing menu. This was considered ineffective and inefficient considering the limited number of employees which was disproportionate to the hectic number of visitors who came. So we need a system that can make it easier to  order menus at  Kedai Wildan. Therefore, a  website-based food  and beverage menu ordering system was created to make it easier for customers and employees. The method used is the data collection method which consists of the observation method, the interview method, the literature study method, and includes the analysis method using the PIECES method, the system development method using the extreme programming method, and the design is carried out using the Unified Modeling Language (UML) method. To test the system using Black Box Testing, namely the login process, managing menu data, and viewing order invoices. With this menu ordering information.
