Artificial Intelligence Integration: Integrated the Gemini AI API to automate the processing and extraction of citizen proposal data into a structured digital format. Decision Support System Development: Implemented a combined calculation of AHP (Analytic Hierarchy Process) and TOPSIS algorithms on the backend to objectively generate the top 5 priority work program recommendations. Master Data Integration: Developed a synchronization module to merge demographic, infrastructure, and regional profile data of Kelurahan Panggungjati as baseline assessment variables. Interactive Analytics Dashboard: Designed a data visualization interface using Recharts to present priority decision reports through intuitive charts and tables tailored for village officials. Automated Reporting Feature: Built a document extraction system to support the direct export of data and recommendation results into PDF format. Authentication and Access Control Management: Implemented Role-Based Access Control (RBAC) using Supabase Auth to separate access privileges and page navigation for Admins, Village Officials, and the Public. Code Standardization and Project Legality: Applied an automated code quality assurance system using Husky and ESLint, and successfully registered and secured official Intellectual Property Rights (IPR/HKI) certification for this digital product.
