Overview

SECCA is a mission-critical enterprise system developed to manage the end-to-end production cycle of bird's nest (feather) processing. Built as a high-performance monorepo, it digitizes every step of the factory floor—from the moment raw materials arrive from suppliers to the final quality control and worker payroll. The system ensures full traceability, operational efficiency, and data integrity across multiple production roles.

Key Features

• Raw Material Lifecycle: Comprehensive tracking of raw batches (Baku) with moisture calculation, weight verification, and supplier integration.
• Complex Lot Splitting (Pecah Bon): Advanced logic for splitting raw batches into production lots with multi-grade assignments (Shape, Color, and Feather condition).
• Kanban-based Production Board: A mobile-responsive digital board for workers (Mitra) to manage their daily tasks through different lanes (Next Day, In Progress, Ready to Submit).
• Automated Payroll Engine: Precise wage calculation based on output weight, shrinkage metrics, and dynamic grade tariffs, replacing manual spreadsheets.
• Enterprise Traceability: Full history of inventory movement across racks and locations, with the ability to trace any finished lot back to its original raw batch and supplier.
• Cross-Platform Deployment: Includes a high-performance NestJS API, a Next.js Web Dashboard, and an Electron Desktop Application with native POS printer integration for the factory floor.

Technologies Used

• Monorepo Architecture: Efficiently managing API, Web, and Desktop applications in a single codebase.
• NestJS & Fastify: High-performance backend with Prisma ORM and PostgreSQL 17.
• Next.js 16 (App Router): Modern, responsive frontend with fine-grained Role-Based Access Control (RBAC).
• Electron: Providing a stable Windows desktop wrapper for factory floor use with native hardware integration.
• Prisma & PostgreSQL: Complex relational data modeling with atomic transactions for inventory and payroll integrity.
• Tailwind CSS & Radix UI: Accessible and professional user interface design.

Challenges and Learnings

Building SECCA required a deep understanding of complex industrial workflows. One of the greatest challenges was architecting a system that handles "shrinkage" (susut) accurately across multiple processing stages while maintaining a clean audit trail. I implemented the Observer Pattern and complex Database Transactions to ensure that inventory levels and payroll records are always in sync, even during concurrent operations on the factory floor.

Outcome

SECCA has transformed the production facility into a data-driven environment. It reduced administrative errors in payroll by 100%, provided real-time visibility into production bottlenecks, and ensured that every gram of material is accounted for, significantly improving the company's bottom line.
