Kalibrasi dan Perhitungan Herbisida

Summary

This video demonstrates the calibration process for a sprayer, focusing on three main goals: assessing the nozzle condition, measuring spray volume, and determining the amount of herbicide per tank. It details the necessary equipment and preparation steps, followed by a step-by-step guide to measure flow rate, nozzle width, and walking speed. The video showcases data collection, calculation of spray volume, and application rates, ensuring accurate pesticide use for effective crop treatment. The tutorial also includes tips for proper calibration to optimize herbicide distribution.

Takeaways

• 😀 Calibration is essential for determining the condition of the nozzle, spray volume, and herbicide per tank.
• 😀 Proper equipment includes a mask, gloves, boots, sprayer, measuring cup, tape measure, bucket, and water.
• 😀 Tools need to be cleaned and checked for leaks before calibration.
• 😀 The first calibration step involves measuring the flowrate in one minute using a set amount of water.
• 😀 The second step involves measuring the travel distance and spray width while walking for one minute with the sprayer.
• 😀 Data from three repetitions of each test is collected to ensure accuracy.
• 😀 The average spray width is calculated to be 0.67 meters after three trials.
• 😀 The average flowrate per trial is found to be 0.5 liters.
• 😀 The average travel distance is 38.6 meters, which is used for further calculations.
• 😀 Spray volume per hectare is calculated using a formula involving the flowrate, spray width, and speed.
• 😀 For a 15-liter tank, 140.1 mL of herbicide is needed based on the spray volume calculated.
• 😀 The calibration process ensures proper herbicide application, maximizing efficiency and ensuring correct dosage per hectare.

Q & A

What is the first objective of the calibration process in the script?

The first objective of the calibration process is to check the condition of the nozzle.

What is the second objective of the calibration process?

The second objective is to determine the spray volume.

What is the third objective of the calibration process?

The third objective is to calculate the amount of herbicide per tank.

What are the key tools and materials needed for the calibration process?

The key tools and materials include a mask, gloves, boots, snap sprayer, measuring cup, tape measure, bucket, and water.

What is the first step in preparing the equipment for calibration?

The first step is to check the equipment's condition by cleaning and inspecting for any leaks.

How is the flow rate measured during the calibration process?

The flow rate is measured by collecting water in a container over a 1-minute period and repeating this measurement three times.

How is the spray width measured in the calibration process?

The spray width is measured by adjusting the nozzle height to 40 cm, walking for 1 minute, and then measuring the width of the spray. This is repeated three times.

What is the formula used to calculate the spray volume?

The spray volume formula is: (10,000 m² per hectare × flow rate) / (spray width × walking speed).

What were the measured flow rates during the calibration process?

The flow rates were 0.4 L, 0.5 L, and 0.6 L for the three trials, with an average of 0.5 L.

How is the herbicide dosage per tank calculated based on the calibration data?

The herbicide dosage is calculated by dividing the recommended dosage (200 mL per hectare) by the calculated spray volume per hectare (212.6 L), and then multiplying by the tank capacity (15 L). This results in 140.1 mL of herbicide per tank.
