<![CDATA[Background: The growing presence of Muslim diaspora communities in non-Muslim-majority societies across East Asia has intensified the urgency for multilingual digital ecosystems capable of sustaining transnational religious cohesion and da'wah coordination. In Hsinchu, a prominent science and technology hub in Taiwan, the Hsinchu Islamic Association (HIA) serves a linguistically heterogeneous Muslim community yet relies on a single Facebook page for all its outward communication.Aims: We aimed to develop and operationalize a multilingual integrated digital platform to foster digital inclusion and empower the Muslim diaspora community in Hsinchu through enhanced access to religious resources and amplified da'wah outreach.Methods: We employed a Participatory Action Research (PAR) framework with the Waterfall software development lifecycle, progressing through needs assessment, system design, implementation, testing, training and handover, and evaluation. User acceptance was assessed through the System Usability Scale (SUS) instrument.Results: The platform was successfully developed as a trilingual website with a synchronized prayer schedule, dedicated service modules encompassing mualaf guidance, Islamic education, religious consultation, and zakat-infaq-sedekah management, alongside a news and events section, community gallery, and embedded location mapping. SUS evaluation with 19 respondents yielded a score of 68.55 out of 100 (SD = 16.19), situating the platform at the empirical benchmark mean of 68 and indicating marginal acceptability, with strengths in ease of use and feature integration. Conclusion: The platform under independent HIA management addresses the digital communication deficit in the Hsinchu Muslim diaspora and furnishes a replicable paradigm for international technology-mediated societal engagement initiatives targeting religious minority communities in non-Muslim-majority societies.]]>
