Teknologi Cegah 87% Breakdown Pabrik Sawit

Apa Itu Predictive Maintenance dan Mengapa Powerful?

Predictive maintenance adalah strategi maintenance yang menggunakan data condition equipment real-time untuk memprediksi kapan komponen akan fail, sehingga maintenance bisa dilakukan pada timing optimal - tidak terlalu cepat (waste cost) dan tidak terlalu lambat (breakdown).

Perbedaan Fundamental:

• Reactive Maintenance: Tunggu rusak → perbaiki (cost tertinggi)
• Preventive Maintenance: Maintenance terjadwal teratur (cost menengah)
• Predictive Maintenance: Maintenance based on actual condition (cost terendah)

Technology Stack Predictive Maintenance:

• Sensors: Vibration, temperature, pressure, current, oil analysis
• Data acquisition: IoT devices dan edge computing
• Analytics: Machine learning dan AI algorithms
• Visualization: Dashboard dan mobile apps
• Integration: ERP, CMMS, dan production systems
