Video Animasi Pembelajaran Teknik Pengukuran Tanah

Summary

In this video, Muhammad Faisal Nugraha, a student of the Building Engineering Education program at UPI, explains the procedure for operating a leveling instrument in land measurement. He highlights the importance of this technique in construction, including planning infrastructure projects like roads, bridges, and buildings. The video covers the components of the leveling instrument, such as the objective lens, focus screws, and mirrors, along with other tools like tripods and measuring tapes. Faisal walks through the step-by-step process of setting up and using the instrument to measure elevation differences between two points, ensuring accuracy and proper equipment handling.

Takeaways

• 😀 The video explains the operation procedure of a leveling instrument, which is crucial in construction projects like building roads, bridges, and buildings.
• 😀 The concept of 'leveling' is introduced as determining the height differences between two or more points using a horizontal line of sight aimed at a reference marker.
• 😀 The importance of land surveying in construction planning and the role it plays in developing infrastructure is highlighted.
• 😀 The key parts of the leveling instrument include the objective lens, screws for adjusting horizontal and vertical levels, a mirror for easy reading, and the ocular lens for observing the target object.
• 😀 The video also discusses other supporting equipment like the tripod, which holds the leveling instrument steady, and the leveling rods used to measure height differences.
• 😀 A description of the procedure for using the leveling instrument is provided, starting with marking the measurement points with stakes.
• 😀 The steps to set up the instrument, including ensuring the tripod is stable and the instrument is leveled, are explained in detail.
• 😀 Adjustments are made to ensure the instrument's bubble level is centered, and the target objects are properly focused for accurate measurements.
• 😀 The importance of taking precise readings from both the back and front benchmarks and recording them on a work sheet is emphasized.
• 😀 The video concludes with a reminder of the safety measures required when working with surveying instruments, such as wearing protective gear to prevent injuries.

Q & A

What is the main purpose of the subject 'Land Measurement Techniques' in construction?

The main purpose of the subject 'Land Measurement Techniques' is to assist in the planning of infrastructure projects such as buildings, roads, and bridges, which are crucial for economic development.

What is the role of 'Sifat Datar' in land measurement?

'Sifat Datar' refers to the process of determining the elevation differences between two or more points using a horizontal line of sight. This technique is essential in designing roads, bridges, irrigation channels, and other construction projects.

What are the components of a level instrument used in land measurement?

The components include the objective lens, adjustment screws (ABC) for leveling the instrument, the horizontal screw for moving the instrument horizontally, the 'Divo' for determining the levelness, the mirror for reading measurements, and the ocular lens for observing the targeted object.

How is the 'Sifat Datar' instrument positioned during use?

The instrument is placed on a tripod, and adjustments are made to ensure it is level. The tripod legs are loosened, and the instrument's height is adjusted. The 'Sifat Datar' is then centered and locked into place.

What is the function of the 'Visir' on the level instrument?

The 'Visir' helps to aim the instrument quickly and efficiently by assisting in the identification of the object being measured.

Why is it important to protect the instrument with an umbrella?

An umbrella protects the instrument from direct sunlight or rain, preventing damage, as the lens of the instrument is highly sensitive to these environmental factors.

What is the purpose of the 'Waterpass' in land measurement?

The 'Waterpass' is used to ensure the level instrument is precisely aligned horizontally, so accurate measurements can be taken.

How is the leveling procedure performed on the instrument?

The leveling procedure involves adjusting the ABC screws to align the bubble within the center of the index line, ensuring the instrument is perfectly horizontal.

What is the role of the measuring tape in land measurement?

The measuring tape is used to determine the distance between reference markers (patok), ensuring accurate measurement of the land area.

What safety equipment is necessary during land measurement procedures?

Safety equipment, such as protective gear, is essential to prevent injury or accidents while working in construction environments.
