SI-SPPG — MBG Kitchen Operations (Go + React)

SI-SPPG manages the work of Satuan Pelayanan Pemenuhan Gizi, the nutrition-service units, from menu planning through meal delivery to beneficiaries. Its backend is written in Go with Fiber, separating domain, service, repository, and presentation layers. PostgreSQL stores data, Redis provides caching, Asynq handles background jobs, and a cron scheduler runs periodic tasks. The frontend is a React and TypeScript application using TanStack Query, Zustand, React Hook Form, Zod validation, Recharts charts, and Leaflet maps.

Its records cover SPPG units, schools, beneficiaries with categories and attendance, suppliers and contacts, farmer groups, allergens, menus and nutritional information, weekly menu plans, inventory items, stock, containers, vehicles, documents, and budgets. Procurement is recorded through purchase orders with approval stages, followed by goods receipt notes. Production plans have sequential progress statuses, quality checks, and retained-sample records. Distribution connects routes, vehicles, schools, and receipt records.

Oversight covers complaints with an SLA dashboard, operational incidents, financial transactions, reports and report templates, audit logs, notifications, and monitoring of documents and certificates approaching expiry. The application also provides public pages with SPPG profiles, schools, beneficiaries, suppliers, and summaries of budget reports and programme progress. Authentication uses JWT with OTP verification and password history, while data access is restricted by module permissions and SPPG unit.
