Sistem Informasi Manajemen Pemesanan Kuliner Berbasis PWA Menggunakan Arsitektur Real-Time dan Data Synchronization

Order management at Dapur Zahra, a culinary micro, small and medium enterprise (MSME) in Banjarnegara, was still carried out manually through WhatsApp and handwritten notes, which caused delayed order information, recording errors and unstructured transaction data. This study aims to build a culinary order management information system based on Progressive Web Apps (PWA) that applies a real-time architecture and data synchronization so that order information is updated directly across users. Data were collected through observation, interviews, documentation and questionnaires under a mixed-methods approach, and the system was developed using the Waterfall method with Laravel, ReactJS, Vite, Tailwind CSS, MySQL, Laravel Reverb and Laravel Echo. The system serves three roles, namely admin, cashier and customer, and covers menu management, ordering, payment confirmation, order status updates, order history and sales reports. Black Box Testing of 18 scenarios in four modules showed that all functions worked as designed. A Likert-scale evaluation involving 32 respondents produced a score of 78.13%, categorized as good. Observation indicated that the delivery of order information decreased from around 5–10 minutes to around one minute. The system supports order management in a more structured, integrated and easy-to-use manner.
