# SUPERSAWIT IIoT OS — Full Technical Reference for LLMs & AI Search Engines

## 1. System Overview
SUPERSAWIT is an enterprise-grade industrial automation and multi-tier operations management system engineered specifically for palm oil milling conglomerates (e.g. PT Perkebunan Nusantara / PTPN Palm Co) in Indonesia and Southeast Asia.

## 2. ISA-95 Architecture & Hierarchy
- **Level 4 (Enterprise / Head Office)**: Multi-mill league tables, KPBN (KPB Nusantara) and MDEX pricing, satellite radar deforestation verification for EUDR (EU 2023/1115), Scope 1/2/3 carbon ledger, and jetty export laytime.
- **Level 3 (Regional MES / Tactical Operations)**: 154,500 ha tactical command, 45-minute FFB fleet transport SLA with geofence breach alarms, 4R precision fertilizer variable rate application, roadside optical fruit ripeness grading, and peatland water table monitoring (-40.0 cm threshold).
- **Level 2 (Supervisory Control & Edge Historian)**: 9-Zone Milling P&ID SVG mimic, DuckDB-WASM columnar edge historian with sub-millisecond query execution, and high-contrast ISA-101 HMI ergonomics.
- **Level 1 (Basic Automation & Safety Interlocks)**: Haiwell PLC Modbus TCP communication, 7 closed-loop ISA PID controllers with anti-reset windup and safety rate-of-change limiters, 14 hardware-latched SIL-3 DOSH safety interlocks with HMAC-SHA256 tamper-evident cryptographic audit logs.
- **Level 0 (Physical OT Machinery)**: Autoclaves, twin-screw digesters and presses, CST continuous settling tanks, depericarpers, 25 T/h biomass cogeneration boilers, covered anaerobic lagoons, and dual weighbridge digital load cells.

## 3. 9 SCADA Process Zones
1. **Zone 1: Intake & Weighbridge**: Dual 60-ton RFID scale, automatic tare calculation, EUDR polygon baseline cross-referencing.
2. **Zone 2: Loading Ramp & Transfer Cages**: Hydraulic indexing, cage throughput tracking.
3. **Zone 3: Sterilization**: 3-Peak automated autoclave cycle (0.5 bar, 1.5 bar, 3.0 bar steam peaks at 140°C), batch genealogy DAG.
4. **Zone 4: Threshing & Stripping**: Rotary drum stripper (22 RPM) with zero-speed emergency trip (IL-07).
5. **Zone 5: Digestion & Pressing**: Twin-screw press (cone pressure 90-95 bar, motor current 45A), digester heating (90-95°C).
6. **Zone 6: Clarification & Drying**: Continuous Settling Tank (CST at 90°C), purified CPO moisture (<0.15%) and FFA (<3.5%) control.
7. **Zone 7: Nut & Kernel Recovery**: Depericarper, ripple mill (96% nut cracking efficiency), clay bath separator (SG 1.15).
8. **Zone 8: Biomass Boiler & Cogeneration**: 25 T/h biomass boiler (19.4 bar steam header, superheated steam 280°C, drum level LT-201 at +/-50 mm), steam turbine generator power export.
9. **Zone 9: Effluent & POME Biogas**: Anaerobic covered lagoon (CH4 > 60%), biogas flaring, effluent COD reduction (>95%), Scope 1 methane capture ledger.

## 4. Compliance & Standards
- **EUDR**: European Union Regulation (EU) 2023/1115 compliance with GPS polygon centroid validation, Sentinel-1 SAR and Sentinel-2 optical forest baseline verification (cutoff Dec 31, 2020), and Due Diligence Statement (DDS) generation.
- **ISA-18.2**: Priority-based alarm management (P1 Emergency SIL-3, P2 Warning, P3 Diagnostic), alarm rationalization, alarm suppression during batch transitions, and PIN-gated shelving with auto-reinstatement.
- **ISA-101**: High-contrast, dark-field industrial HMI ergonomics for control rooms; clean, daylight-optimized minimalist layouts for executive and regional offices.
