Integrated Manufacturing Production System

Project Manager & Lead Architect

A multi-module internal manufacturing web ecosystem on Laravel — covering PPIC forecasting through purchasing, production, and inventory — deployed on Ubuntu VPS with Nginx and a CI/CD release pipeline.

  • Forecast PPIC — production planning & demand forecasting

  • Production (Produksi) tracking & execution
  • Inventory reporting (raw & finished goods)
  • Inbound RAW Material intake & ledger
  • Outbound / sales dashboard with per–police-plate monitoring
Impact

Unified PPIC, procurement, production, and logistics into one platform — giving operations real-time visibility from raw-material inbound through outbound dispatch by vehicle plate.

End to End IT System

Lead Developer & DevOps Engineer

A Django-based IT Department platform that runs the full internal stock lifecycle — from Purchase Requisitions through inbound/outbound movements and inventory adjustments — with daily and monthly inventory reports, asset tracking, IT operational administration, a CRUD panel with export functionality, and Docker deployment.

  • Stock flow pipeline: PR → inbound/outbound → adjustments
  • Daily & monthly inventory reporting dashboards
  • Asset & inventory tracking with movement history
  • IT operational administration (policies, docs, ops records)
  • CRUD admin panel with CSV/Excel export
  • Dockerized deployment on Linux + Nginx + PostgreSQL
Impact

Replaced fragmented spreadsheets and manual stock logs with one end-to-end system — giving the IT department auditable stock flow, scheduled reporting, and repeatable Docker-based releases.

Purchase Document Pipeline Monitor

Fullstack Developer

A web app that monitors the full BPS procurement pipeline — PR → PO → GR → PI/AP. It imports SAP Business One Excel exports, enriches them against master data with document aging and status, and surfaces dashboards, filters, exports, and automatic stuck-PR detection so procurement never stalls silently.

  • PR → PO → GR → PI/AP pipeline tracking
  • SAP Business One Excel report ingestion
  • Master-data enrichment with aging & status
  • Stuck-PR detection & bottleneck alerts
  • Interactive dashboards with filtering
  • Data exports for finance & procurement review
Impact

Gave procurement and finance a single live view of every document's stage and age — catching stuck PRs early and cutting manual SAP Excel reconciliation.

BPS Point Rewards

Fullstack Developer & Architect

An employee points & rewards gamification platform: staff earn points from KPI achievements, climb tiers (Bronze → Diamond), and redeem rewards via PDF vouchers emailed to HR. Built with a modular Django architecture designed to plug into the parent "Web Center" multi-module portal.

  • KPI-driven points with 5-tier system (Bronze → Diamond)
  • Employee portal: dashboards, point timeline, reward journey
  • Reward claim → auto-generated PDF voucher + email to HR
  • HR panel: CRUD, bulk point adjustment, Excel import/export
  • Session auth (employee_id + NIK) with is_hr RBAC guards
  • Enterprise audit log (login, CRUD, bulk, claims) with IP/metadata
  • Modular apps + Web Center hub integration (subpath mount)
Impact

Turned KPI performance into a transparent, gamified rewards loop — automating point balances via signals, voucher issuance, and giving HR full control with auditable, exportable data.

Industrial Internet Infrastructure

Network & Infrastructure Engineer

A resilient internet and network infrastructure for a steel manufacturing site with complex physical terrain, combining fiber optic backbone links and point-to-point wireless AP bridges to reach office, production, and operational zones reliably.

  • Hybrid backbone: fiber optic links + PtP wireless AP bridges
  • Two network segments for office and production environments
  • VPN setup for secure remote and inter-site access
  • Bandwidth management for critical business and production traffic
  • Cisco ASA perimeter security implementation
  • Dual ISP design: primary connection + backup/failover path
Impact

Delivered a more reliable and maintainable network foundation for steel manufacturing operations — improving connectivity reach, traffic control, remote access security, and internet continuity during ISP disruption.

Multi-Site Industrial CCTV Infrastructure

CCTV & Infrastructure Engineer

A large-scale CCTV rollout built in parallel and expanded continuously across three steel manufacturing sites in demanding terrain — delivering a secure, stable surveillance backbone that handles 300+ camera endpoints mixing digital IP and legacy analog feeds with minimal operational downtime.

  • 300+ CCTV endpoints across 3 manufacturing sites
  • Hybrid digital (IP) + analog camera integration
  • Phased parallel deployment — live ops while expanding coverage
  • Designed for heavy industrial environments & complex site layout
  • Stable live view & recording under high camera density
  • Maintenance and expansion with minimal downtime windows
Impact

Gave security and operations site-wide visibility across multiple plants without halting production — a scalable CCTV platform that keeps running while new zones and cameras are added.

Dual Local Data Center with OpenMediaVault

Storage & Infrastructure Engineer

Two local data-center storage environments built from zero using OpenMediaVault as the central data repository for employees across two steel manufacturing companies — planned, installed, configured, secured, and handed over into daily production use.

  • 2 local data centers for 2 steel manufacturing companies
  • OpenMediaVault-based centralized employee file storage
  • End-to-end setup from hardware planning to live operation
  • Shared folder structure, user access, and permission governance
  • Local network integration for daily department workflows
  • Operational handover so teams can use storage normally
Impact

Created reliable local storage foundations for employee and department data — replacing scattered file practices with controlled access, centralized organization, and easier maintenance.

Multi-Entity MySQL Backup Automation

DevOps & Infrastructure Engineer

A centralized backup pipeline for nine production web systems — each running on its own VPS — with dedicated Bash scripts per entity that pull daily incremental MySQL dumps into a single Ubuntu storage host for traceability, reliability, and fast restore.

  • 9 VPS entities → 9 websites, 9 independent .sh backup scripts
  • Daily incremental MySQL backups (per-entity retention)
  • Centralized archive on one Ubuntu backup server
  • Structured paths so every dump is traceable by entity & date
  • Cron-driven automation — hands-off daily runs
  • Restore playbooks designed for quick single-entity recovery
Impact

Replaced ad-hoc manual dumps with a predictable, auditable backup rhythm across all entities — one place to know where data lives and how to bring any system back online.
