Praktikum Pengenalan dan Penggunaan Mikroskop | Biologi Umum | UPT Laboratorium Terpadu UHO

Summary

Welcome to the Integrated Laboratory at UN, where we serve students from 21 different programs. This video introduces the principles of light microscopy, its parts, and usage. The lab is equipped with four staff and assistants to guide students through the semester. The tutorial covers the use of a light microscope, starting with the lowest magnification and gradually increasing, focusing on the object with coarse and fine focus adjustments. The goal is to familiarize students with the essential aspects of light microscopy.

Takeaways

• 📝 Welcome to the Integrated Laboratory at UN, where the biology lab is managed by Dokoraka and the geology unit is headed by MSC.
• 📝 The lab serves students from 21 different programs at Salu Leo University for both odd and even semesters.
• 📝 The lab is staffed with four assistants who will assist students throughout their practical sessions until the end of the semester.
• 📝 The first practical session introduces the use of a light microscope.
• 📝 The goal of the practical session is to familiarize students with the important principles of light microscopes, their parts, and their usage.
• 📝 The lab uses light microscopes and permanent slide preparations, known as monokotils.
• 📝 There are two main types of microscopes: light microscopes and electron microscopes.
• 📝 Light microscopes use light waves as a source of illumination and consist of several parts including the eyepiece lens, objective lens, diaphragm, coarse and fine focus adjuster, tube, arm, and stage.
• 📝 The eyepiece lens is for magnifying the image from the objective lens, while the objective lens magnifies the object's image.
• 📝 The diaphragm controls the amount of light entering, and the focus adjusters help in focusing the object's image.
• 📝 The stage is where the specimen is placed and can be moved up, down, or sideways, and it is equipped with a clip to hold the specimen.
• 📝 The use of the microscope involves placing it on the edge of the table, connecting it to a light source, placing the specimen on the stage, and observing through the eyepiece lens starting with the lowest magnification.

Q & A

What is the purpose of the laboratory mentioned in the script?

The laboratory serves students from 21 different study programs at the university, providing services for both odd and even semesters.

Who are the staff members introduced in the script?

The script introduces MSC as the head of the laboratory unit of geology and dokoraka as the biology laboratory assistant.

What is the main goal of the practical session described in the script?

The main goal is for students to understand the important principles of light microscopes, their parts, and their usage.

What are the two main types of microscopes mentioned in the script?

The two main types of microscopes are light microscopes and electron microscopes.

How does a light microscope function according to the script?

A light microscope uses light waves as its illumination source.

What are the main parts of a light microscope as described in the script?

The main parts include the eyepiece lens, objective lens, diaphragm, coarse and fine focus adjuster, tube, arm, stage, and base or foot of the microscope.

What is the function of the eyepiece lens in a light microscope?

The eyepiece lens is used to magnify the image from the objective lens.

What is the role of the diaphragm in a light microscope?

The diaphragm is a perforated plate that functions to regulate the amount of light entering the microscope.

How does the focus adjuster on a light microscope work?

The focus adjuster, located in the middle of the microscope, is used to adjust the focus of the object's image.

What is the function of the stage in a light microscope?

The stage is where the specimen is placed and it can be moved up, down, or sideways, and it is equipped with a clip to hold the specimen.

What is the procedure for using a light microscope as outlined in the script?

The procedure includes placing the microscope on the edge of the table, connecting it to a light source, placing the specimen on the stage, adjusting the stage position, observing through the eyepiece, starting with the lowest magnification, and then focusing with the coarse and fine focus adjusters.

What is the purpose of the base or foot of the microscope?

The base or foot of the microscope serves as the stand to hold the microscope stable.
