Perkembangan teknologi informasi mendorong digitalisasi berbagai layanan, termasuk layanan katering yang sebelumnya masih banyak dikelola secara manual. sistem pemesanan dan pengelolaan langganan katering secara konvensional berpotensi menimbulkan kendala dalam pencatatan pesanan, pengelolaan data pelanggan, serta pemantauan transaksi. penelitian ini bertujuan untuk merancang dan membangun aplikasi langganan katering berbasis web mobile menggunakan metode rapid application development (rad). metode rad dipilih karena menekankan proses pengembangan secara iteratif dengan keterlibatan pengguna pada setiap tahap perancangan dan implementasi sistem. aplikasi yang dikembangkan menyediakan fitur pemesanan paket katering, pengelolaan langganan, serta pemantauan status pesanan bagi pelanggan, sementara dari sisi admin disediakan fitur manajemen paket, transaksi, dan data langganan. pengujian sistem dilakukan menggunakan metode black box testing untuk memastikan fungsionalitas berjalan sesuai kebutuhan, serta pengujian usability menggunakan system usability scale (sus) untuk menilai tingkat penerimaan pengguna. hasil pengujian menunjukkan bahwa seluruh fungsi utama sistem dapat berjalan dengan baik dan aplikasi memperoleh skor sus sebesar 83,75 yang termasuk dalam kategori good. dengan demikian, aplikasi langganan katering berbasis web mobile yang dikembangkan dinilai mampu mendukung proses pemesanan dan pengelolaan langganan katering secara terkomputerisasi. kata kunci: sistem langganan katering, web mobile, rapid application development (rad), black box testing, system usability scale.

The development of information technology has encouraged the digitalization of various services, including catering services that are still widely managed through manual processes. Conventional catering subscription and order management systems may cause problems related to order recording, customer data management, and transaction monitoring. This study aims to design and develop a mobile web–based catering subscription application using the Rapid Application Development (RAD) method. The RAD method was selected due to its iterative development process and active user involvement at each stage of system design and implementation. The developed application provides features for ordering catering packages, managing subscriptions, and monitoring order status for customers, while the admin side supports package management, transaction handling, and subscription data management. System testing was conducted using the Black Box Testing method to verify system functionality, along with usability testing using the System Usability Scale (SUS) to evaluate user acceptance. The testing results indicate that all main system functions operate as intended, and the application achieved a SUS score of 83.75, which falls into the Good category. Therefore, the developed mobile web–based catering subscription application is considered capable of supporting computerized catering subscription and order management processes.
