Abstract. Digital transformation in education requires efficient administrative systems to overcome manual process limitations. This research analyzes and designs an online registration information infrastructure integrated with digital payment systems at SD Islam Tahfiz Quran Daarussunnah using Structured System Analysis and Design Method (SSADM) methodology. System design utilizes Entity Relationship Diagrams, Logical Record Structures, and Unified Modeling Language to construct robust database architecture. Implementation employs Laravel framework with Midtrans payment gateway integration enabling various digital payment methods accompanied by automatic WhatsApp notifications and PDF transaction receipt printing. Black Box testing validates system functionality, White Box Testing yields cyclomatic complexity value of 2, while User Response evaluation involving 34 respondents demonstrates high satisfaction levels with 68.24% extremely satisfied with design and performance, and 71.76% with overall satisfaction. This system significantly enhances administrative process efficiency, data recording accuracy, and payment transaction transparency, simultaneously eliminating risks of physical document loss and manual data entry errors frequently occurring in conventional systems.
