Abstract
<jats:p>The tourism sector has recently shown potential as a driver of global economic growth, inspiring optimism for economic advancement in many countries. However, the Covid-19 pandemic disrupted this sector, leading to a sharp decline in tourism, including in West Nusa Tenggara (NTB) Province. Research involving halal tourism experts, travel practitioners, hotels, tourism offices, and stakeholders indicates that halal tourism has become a notable trend on Lombok Island, with promising economic potential supported by regulatory and sustainable frameworks. Despite this potential, technological challenges remain. This study addresses these challenges by developing a backend system for an integrated halal tourism application for web and mobile platforms, targeting hotels, transportation, and tourism agents. Using the SCRUM methodology, Hapi.js for the backend, PostgreSQL for primary data management, and Redis for caching, the system employs a REST API, ensuring secure, efficient data management and meeting halal certification standards on Lombok Island.</jats:p>
