Sampling Air Permukaan

Introduction

This tutorial provides a step-by-step guide on how to sample air from surface water, as demonstrated in the video "Sampling Air Permukaan" by BSPJI Banjarbaru. Understanding how to collect air samples is crucial for environmental monitoring and assessing air quality. This guide will cover the necessary equipment, sampling techniques, and best practices to ensure accurate results.

Step 1: Gather Necessary Equipment

To begin sampling air from surface water, you will need the following equipment:

• Sampling bottles: Ensure they are clean and suitable for air sampling.
• Pumps: Use an air sampling pump to draw air from the desired location.
• Tubing: Connect the pump to the sampling bottles.
• Protective gear: Wear gloves and masks to ensure safety during the sampling process.

Practical Advice

• Check that all equipment is calibrated and functioning properly before use.
• Choose sampling bottles that are compatible with the type of analysis you plan to conduct.

Step 2: Select Sampling Locations

Identify appropriate locations for air sampling, focusing on areas near surface water bodies.

Considerations for Location

• Proximity to water: Select spots that are close enough to capture air influenced by the water.
• Environmental factors: Avoid areas with heavy traffic or industrial activity that may skew results.
• Accessibility: Ensure the site can be safely reached for sampling.

Step 3: Perform the Sampling

Follow these steps to collect air samples effectively:

1. Set up the equipment: Position the pump and connect the tubing to the sampling bottles.
2. Begin sampling: Turn on the pump to start drawing air. Monitor the flow rate to ensure consistency.
3. Sample duration: Allow the pump to run for a predetermined time, typically between 10 to 30 minutes, depending on the study's requirements.
4. Shut off the pump: Once the sampling duration is complete, turn off the pump and disconnect the tubing.

Practical Advice

• Record the sampling time and environmental conditions during the process for future reference.
• Ensure that the sampling bottles are sealed immediately after collection to prevent contamination.

Step 4: Transport and Store Samples

After collecting the air samples, proper handling is essential for maintaining their integrity.

• Label samples: Clearly label each bottle with relevant information (date, time, location).
• Store samples: Keep the samples in a cool, dark place to minimize degradation before analysis.
• Transport samples: If sending samples to a lab, use insulated containers to maintain temperature.

Common Pitfalls to Avoid

• Do not expose samples to direct sunlight or extreme temperatures.
• Ensure all samples are transported as quickly as possible to the analysis laboratory.

Conclusion

Sampling air from surface water is a vital procedure for environmental monitoring. This guide has outlined the necessary equipment, techniques for selecting locations, sampling methods, and best practices for handling samples. By following these steps, you can ensure accurate and reliable air quality assessments.
