This study analyzes the design and implementation of an integrated system using N8N for Bank Koperasi Syariah Indonesia in Aceh Province (Kopebi Aceh). The five operational modules were developed using a Research and Development (R&D) approach with a prototype model. These modules include Point of Sale, Sharia Financing, Financial Reporting, and Membership Management. The system uses N8N as a workflow automation platform, connecting various services through webhooks and embedding Sharia-compliant business logic using Function Nodes. Performance evaluation conducted two months after implementation showed significant technical improvements: response time was reduced by 88.6%, throughput increased by 466.7%, and downtime was reduced by 94.1%. Operational efficiency also experienced a remarkable increase, with transaction processing time reduced by 85.6%, data entry errors reduced by 96.6%, and monthly reporting time reduced by 99.2%. These improvements resulted in improved organizational outcomes, including a 23.3% increase in operating revenue, a 65.3% decrease in operating expenses, a 29.2% increase in profit margins, and a 47.1% increase in member profit sharing. User surveys indicated a positive perception of the system, with all dimensions scoring above 4.5 on a 5-point scale. Compliance with Sharia principles also increased from 85% to 99%, reflecting compliance with Islamic financial standards. Low-code/no-code platforms such as N8N can effectively facilitate the digitalization of Sharia cooperatives without requiring significant investment in software development. The proposed development model is a practical reference for other Sharia cooperatives in Indonesia seeking to improve efficiency and ensure regulatory compliance.
