PENGUKURAN PENCEMARAN UDARA AMBIEN | Labtalk #25

Summary

This video discusses air pollution, its health effects, and how air quality is monitored in Indonesia. Expert Anwar Hadi explains the regulations set by Government Regulation No. 22 of 2021, detailing air pollution parameters, measurement standards, and methods. He emphasizes the importance of accredited laboratories and proper calibration of equipment for valid air quality monitoring. Challenges in calibrating particulate matter instruments and ensuring accurate data are also addressed. Viewers are reminded of the importance of protecting their health and staying informed about air quality, particularly in areas with high pollution levels.

Takeaways

• 😀 Air pollution is a growing issue that significantly affects respiratory health and increases cases of acute respiratory infections (ISPA).
• 😀 Air pollution is defined as the introduction of harmful substances or energy into the ambient air due to human activities, exceeding established air quality standards.
• 😀 Indonesian Government Regulation No. 22 of 2021 sets the air quality standards (Baku Mutu Udara) for various pollutants like SO2, CO, NO2, O3, NMHC, PM10, PM2.5, and Pb.
• 😀 Measurement of air pollutants is done at different time intervals (1 hour, 8 hours, 24 hours, or 1 year) using active continuous and manual monitoring methods.
• 😀 Active continuous monitoring uses sensors for real-time air quality data, while manual methods require sampling and laboratory testing.
• 😀 The selection of air monitoring locations should prioritize areas with high pollution levels, such as near industrial zones and densely populated areas, while considering wind, temperature, and geographical factors.
• 😀 Air monitoring stations should be placed safely, away from interference like trees and buildings, with specific height guidelines (3-6 meters for permanent stations).
• 😀 Only accredited laboratories with ISO 17025 certification are authorized to conduct official air quality monitoring, ensuring the validity of the collected data.
• 😀 Real-time air quality data is increasingly available through social media and mobile apps, but it’s essential to ensure the monitoring tools are properly calibrated and the institutions are accredited.
• 😀 Calibration issues are a challenge, especially for particulate matter, as certified calibration gases are not widely available, hindering accurate measurements.
• 😀 Proper air quality monitoring and adherence to regulations are critical to ensuring valid data and protecting public health from the harmful effects of air pollution.

Q & A

What is air pollution as defined by the Indonesian Government Regulation No. 22 of 2021?

Air pollution is the introduction of harmful substances or energy into ambient air due to human activities, which exceeds the air quality standards established by the government.

What are the key parameters for measuring air quality according to the government regulation?

The key parameters include sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), methane hydrocarbons (NMHC), particulate matter (PM10 and PM2.5), and lead (Pb).

What are the time frames for measuring sulfur dioxide (SO2) concentrations according to the regulation?

Sulfur dioxide (SO2) is measured over time frames of 1 hour (150 µg/m³), 24 hours (75 µg/m³), and 1 year (45 µg/m³).

How is air quality measured continuously and manually?

Air quality can be measured continuously using automatic sensors (active continuous systems) or manually using specific equipment like impingers and samplers.

What is the significance of the SNI 19719.65 standard in air quality monitoring?

SNI 19719.65 provides criteria for selecting monitoring locations, emphasizing areas with high pollutant concentrations, and factors like wind direction, industrial emissions, and population density.

What criteria must be met for valid and representative sampling of ambient air?

Sampling should avoid areas where air concentrations might be altered by nearby buildings, vegetation, or emissions from local sources like vehicles and kitchens.

Where should air quality monitoring equipment be placed to ensure accurate data collection?

Monitoring equipment should be placed in safe, representative areas, preferably on building rooftops, at least 15 meters from roadways, and at appropriate heights depending on the type of monitoring.

What is the difference between 'ambient air' and 'roadside air' in air quality monitoring?

Ambient air refers to air quality at locations not directly influenced by nearby roads, while roadside air, located 1-5 meters from roadways, is considered to be affected by vehicular emissions and not representative of general ambient air.

Who is authorized to perform ambient air quality monitoring in Indonesia?

Only laboratories accredited and registered by the Ministry of Environment and Forestry (KLHK) are authorized to perform ambient air quality monitoring. These labs must meet ISO 17025 standards.

What challenges exist in the calibration of air quality monitoring equipment?

Challenges include the unavailability of certified calibration gases for specific parameters and the difficulty in calibrating particulate matter monitoring equipment (e.g., PM10, PM2.5) due to the lack of capable labs.
