Manufacturing + MRP + Quality Management + OEE: Pondasi pabrik digital 2026

Pabrik Indonesia di 2026 sudah tidak bisa run dengan spreadsheet MRP + manual Quality reject log. Industri 4.0 wave yang dimulai 2018-2020 sudah jadi requirement minimum, dan board investor expect KPI manufacturing real-time: OEE %, Yield Variance, MTBF, MTTR, Quality reject ppm. Artikel ini bahas pondasi 4 modul manufaktur yang harus terintegrasi dalam ERP modern: BOM multi-level, MRP, Quality Management, dan Asset Maintenance dengan OEE.

BOM (Bill of Materials) multi-level

BOM adalah tulang punggung manufaktur — daftar komponen + quantity yang dibutuhkan untuk produce satu unit finished good. Untuk produk simple (mis. air mineral kemasan), BOM 1-level: 1 botol PET + 1 cap + 1 label + 600ml air = 1 unit. Untuk produk kompleks (mis. food processing dengan recipe), BOM bisa 10+ level: raw → ingredient mix → sub-assembly → finished.

Capability yang harus ada:

• Multi-level BOM dengan auto-rollup cost (cost of finished = sum of all level cost + conversion cost)
• Substitute item — kalau primary out of stock, auto-suggest substitute (mis. supplier A out, pakai supplier B dengan harga 5% lebih mahal)
• Alternate routing — kalau line A maintenance, route ke line B
• Phantom assembly — sub-assembly yang tidak distock physically tapi di-track for costing
• Yield factor — recipe-based manufacturing dengan expected yield 95% (raw 1.000 kg → finished 950 kg karena waste)

Tyrex BOM module handle ketujuh capability di atas. Auto-rollup cost setiap kali raw material price update.

MRP (Material Requirement Planning) scheduled

MRP adalah algoritma yang explode demand forecast → required raw material → suggest PR/PO. Untuk pabrik dengan 1.000+ SKU dan lead time supplier 30-90 hari, MRP manual via Excel sudah tidak feasible.

MRP run:

1. Demand input: Sales forecast + Sales Order confirmed + Safety Stock minimum
2. BOM explosion: untuk setiap finished good demand, hitung quantity raw material needed
3. On-hand check: subtract current stock + open PO + open WO
4. Net requirement: gap = demand - available
5. Action suggest: PR otomatis dengan supplier suggested, quantity, dan need-by date

Tyrex MRP run scheduled (daily/weekly) atau on-demand. Output PR auto-routed ke procurement approval workflow.

Quality Management — Holds, sampling, rejects

Quality issue di pabrik FMCG/Pharma/F&B punya consequence high (recall, product safety). Quality Management modul handle:

• Inspection checkpoint: setiap stage produksi (raw incoming, in-process, finished outgoing) ada checkpoint quality
• Sampling plan: ANSI/ASQ Z1.4 statistical sampling (mis. AQL 1.5 untuk minor defects)
• Quality Hold: batch yang fail inspection masuk Quarantine, tidak bisa ship sampai disposisi (rework/scrap/concession)
• Reject routing: scrap → inventory write-off, rework → re-route ke production
• CAPA tracking: Corrective Action / Preventive Action untuk root cause

Tyrex Quality Management terintegrasi dengan Production WO + Inventory — Quality Hold lock physical movement di Inventory sampai disposisi.

Asset Maintenance + OEE + MTBF/MTTR

Mesin manufaktur adalah aset Rp 100 juta - 50 miliar yang harus di-maintain proaktif. ERP modern track:

• OEE = Availability × Performance × Quality. World-class manufacturer target OEE 85%, Indonesia rata-rata 50-65%
• MTBF (Mean Time Between Failures): jarak waktu rata-rata antara breakdown
• MTTR (Mean Time To Repair): durasi rata-rata recovery dari breakdown
• PM Schedule: preventive maintenance scheduled (mis. service oil ganti per 500 jam runtime)
• Spare parts inventory: critical spare yang harus selalu in-stock

Tyrex Asset Maintenance auto-calculate KPI ini dari production downtime log + maintenance work order. Dashboard real-time per mesin per line.

Yield Variance reporting per batch

Yield variance = (Actual yield - Expected yield) / Expected yield. Negative variance = waste/loss tinggi → margin tergerus. Untuk pabrik food processing dengan margin tipis (5-10%), 1% yield variance bisa = miliar rupiah/tahun.

Tyrex auto-calculate yield variance per Work Order (Production Batch): track raw material consumed (Material Issue) vs finished good output (Production Receipt). Variance >threshold trigger alert ke QC manager untuk investigation.

Work Order lifecycle

Tipikal WO:

1. WO Created dari MRP suggestion atau manual demand
2. Material Reservation — raw material reserved di Inventory (tidak available untuk WO lain)
3. Material Issue — physical issue ke production floor
4. Production Posting — operator scan barcode WO + report output quantity + downtime
5. Quality Inspection — final goods QC pass/hold
6. Production Receipt — finished good masuk Inventory
7. WO Close — yield variance + cost variance calculated, journal entry posted

End-to-end tracked di Tyrex Manufacturing + Inventory + Finance dalam satu database.

Integrasi ke ERP modul lain

Manufacturing tidak standalone — connect ke:

• Procurement: MRP suggest PR → Procurement create PO → goods received update Inventory
• Inventory: material reservation + issue + receipt
• Sales: Make-to-Order vs Make-to-Stock policy
• Finance: cost variance posting ke GL
• HR: operator timesheet → labor cost allocation

Tyrex semua dalam 1 platform — tidak ada API integration drama.

Kesimpulan

Manufaktur modern butuh BOM + MRP + Quality + Asset/OEE integrated. Tyrex Manufacturing Suite (di tier Pro+) handle semuanya. Discovery untuk pabrik: [email protected] atau lihat /modules untuk detail tiap submodul.
