PRAKTIK ILMU UKUR LAHAN (Pembuatan Profil atau Pelurusan) FAKULTAS KEHUTANAN ULM 2020

Summary

This tutorial explains the steps involved in land surveying practices for forestry, focusing on tools and techniques. The process includes setting up reference points, calibrating GPS for accurate coordinates, using a compass to determine directions, and measuring distances and slopes using tools like a clinometer. The data gathered is then used to create a profile, helping with land contour analysis. The video provides a detailed guide for forestry students at Universitas Lambung Mangkurat on how to conduct a land survey, emphasizing accuracy and proper technique for a successful outcome.

Takeaways

• 😀 Step 1: Place a reference marker (jalon) at point T1 to begin the land measurement process.
• 😀 Step 2: Mark the measurement path at eye level for accurate data collection.
• 😀 Step 3: Calibrate the GPS before use to ensure accurate coordinate and elevation readings.
• 😀 Step 4: Use a compass to determine the azimuth from point P1 to P2 and record the data.
• 😀 Step 5: Follow the compass directions to ensure the survey path is correctly aligned.
• 😀 Step 6: Place a second marker (jalon P2) at a point where the terrain changes.
• 😀 Step 7: Measure the distance between points P1 and P2 using a measuring tape or meter.
• 😀 Step 8: Measure the slope between P1 and P2 using a clinometer and record the data.
• 😀 Step 9: Repeat the process for further segments (P2 to P3, etc.), continuing to measure distance and slope.
• 😀 Step 10: Ensure that all collected data is logged accurately into a record book (Talisit) for reference.

Q & A

What is the first step in the land measurement practice described in the script?

The first step is to place a marker (jalon) at the T1 or waypoint location.

Why is it important to ensure that the GPS is calibrated before use?

It is important to calibrate the GPS to ensure the accuracy of the coordinates and elevation data obtained during the measurement.

What role does the compass play in the land measurement process?

The compass is used to align the direction from point P1 to P2 and determine the azimuth for accurate measurement.

What should be done after determining the azimuth?

The azimuth data should be written down into the logbook for reference.

What is the purpose of the surveying step involving 'perintisan'?

The surveying step called 'perintisan' is conducted to ensure the measurements are thorough and follow the determined direction accurately.

When should the second marker (jalon) be placed?

The second marker (jalon) is placed at a location where there is a change in terrain or contour.

What instrument is used to measure the distance between points P1 and P2?

A measuring tape or meter is used to measure the distance between points P1 and P2.

How is the slope between P1 and P2 measured?

The slope between P1 and P2 is measured using a clinometer.

What should be done with the slope and distance data obtained?

The data obtained for slope and distance should be recorded in the logbook for further analysis and reference.

What happens after the measurements from P2 to P3 are taken?

Once the measurements from P2 to P3 are taken, the data is entered into the logbook, and the process continues by moving the marker (jalon) to the next point.
