System Technology

Sensor & Analyzer

Using UV Fluorescence (SO₂), Chemiluminescence (NOx), NDIR (CO/CO₂), Gravimetric & Beta Ray Attenuation (PM).

Data Acquisition System (DAS)

Logging & real-time transmission to central server.

Communication Protocol

GPRS/4G/5G, Radio Telemetry, Satellite (optional).

Data Management

Integration into government platforms (KLHK SispeK / Simpel Onlimo).

Advantages & Benefits

Real-time Data Availability

Water and air quality data is directly accessible to operators & regulators → enabling rapid response to pollution incidents.

Cost Efficiency

Reduces the need for manual sampling & laboratory analysis → saves long-term monitoring costs.

Public Transparency

Monitoring data is accessible to the public → supports information transparency, corporate CSR, and public participation.

Regulatory Compliance

Supporting compliance with government regulations (KLHK, PP 22/2021, Decree of the Minister of Environment 13/1995, and international standards).

Integration Ready

The system can be integrated into a multi-site dashboard for regional & national monitoring.

Main Applications

Industrial

Power plant, oil & gas, petrochemical, pulp & paper, manufacturing.

Government

Urban air quality monitoring station (AQMS), river & lake monitoring (Onlimo).

CSR & ESG Compliance

Supporting companies in sustainability reporting and environmental responsibility.

With Onlimo & AQMS solutions, PT. Hidea Inti Daya ensures high-accuracy, real-time environmental quality monitoring that meets international standards, supporting sustainability and regulatory compliance.
