<![CDATA[Bantuan Langsung Tunai Dana Desa (BLT-DD) administration requires accurate beneficiary records, structured verification, and accessible information for residents and village officials. In the case examined, existing procedures relied on manual data recording, resulting in slow verification, potential duplication of resident records, time-consuming report preparation, and limited mechanisms for residents to monitor application status. This study develops a mobile web-based information system to integrate these administrative processes within a single platform. A Waterfall development model was applied through requirements analysis, system design, implementation, testing, and maintenance. System requirements were identified through a structured interview with the village secretary and direct observation. Unified Modeling Language (UML) was used to model the system through use case, activity, sequence, and class diagrams, while the application was implemented using PHP, HTML, and MySQL. The resulting system supports resident registration and authentication, BLT-DD information access, online cash-transfer applications, supporting-document submission, application verification, beneficiary management, distribution information, reporting, and application-status checking. The implementation establishes an integrated workflow linking resident submission, administrative verification, beneficiary records, distribution information, and status communication within a mobile-accessible web environment. However, the available evidence does not include quantitative usability, security, performance, or complete scenario-level functional-testing results. Accordingly, the study demonstrates requirements-driven system integration rather than comprehensive system effectiveness. Future evaluation should incorporate validated usability measures, security assessment, performance testing, and fully documented functional-test outcomes to provide stronger evidence of system quality and operational reliability.]]>
