Foreword

Thank you we pray to Allah SWT so that the preparation of this paper can be completed in time. In addition, we would like to express our deepest gratitude to the “COMPUTER & COMMUNITY” lecturers for their guidance and motivation.

Computers and Communities are courses that really need to be developed and understood considering their huge role in education, especially in the IT field with its code of ethics and problems, especially problems that we discuss all kinds of businesses in the world or the computer field.

The author is aware of the shortcomings in the preparation of this paper. Because of that we really hope for constructive criticism and suggestions from all parties for the perfection of this paper.

CHAPTER I

PRELIMINARY

1.1 Background

Computers have now been widely used by the general public, both in offices and in housing. Because it is considered to facilitate a job. Computers are also widely used by various professions, such as designers, instructors, accountants, photographers, and much more. Because computers are considered to have multiple functions. But behind its versatility, computers can also damage our health, especially the eyes. Because the radiation released by the monitor or computer is what can interfere with eye health. Along with the development of technology, computer radiation can be minimized. Formerly a computer monitor screen shaped like a beam, very large and the radiation produced was also quite large. But now the monitor screen is slim and the radiation is getting smaller, or often called the LCD screen.
1.2 Identification of Problems

The research problems that the authors propose can be identified as follows:

Understanding the monitor
Effect of monitor radiation
How to Maintain Eyes to Avoid Monitor Radiation
Impact of Monitor on Human Physicality

1.3 Problem Formulation

What does the monitor mean?
How does the monitor radiation affect?
How do you keep your eyes protected from radiation monitors?
What impact does the monitor have on the physical human being?

1.4 Purpose of Writing

Can know the meaning of the monitor
Can know the effect of monitor radiation
Can know how to maintain to avoid radiation monitors
Can know the impact of the monitor on human physical

DISCUSSION

2.1 Definition of Monitor

Monitor or with another term called VDU (Video Display Unit), is one of the most important parts of a computer unit. This monitor part is what we often see when we use a computer. The function of the monitor is to visualize data or processes that occur in the CPU visually. The process that occurs in the CPU (Central Processing Unit) is converted by a “Video / Video board adapter” from digital data to a signal that will be channeled through the connecting cable to the monitor.Monitors that use a CRT system (Cathode Ray tube) work by emitting electrons. These electrons sweep the screen from left to right with paths from top to bottom in a pattern called “raster” CRT or more commonly called a Cathode Ray Tube is a wrapper tube made of glass and contains an arrangement of electron shooters and ejects a file electron files directed at fluorescent screens. When the beam is exposed to light, the screen emits light with a longer wave. These electron beams give rise to bright light. Depending on the intensity of the electron beam earlier. This light disappears very quickly. For that the electron beam must still sweep the screen regularly to maintain the blast that occurs. This is commonly called refreshing or “refreshing” the screen. Monitors generally have a refresh rate (vertical scan rate) of 60 hertz, which means that the screen is refreshed 60 times per second. If the refresh rate is low, the screen will appear blinking. This will quickly tire our eyes, so instead we use a monitor with a “vertical scan rate” of 70 hertz and above is good enough to use.

2.2 Effect of Monitor Radiation

Broadly speaking, some health problems that are caused by computer use are known, including Repetitive Stress / Strain Injury (RSI), Eye Fatigue and Headaches, Asthenopia, Pain and other disorders,

Repetitive Stress / Strain Injury (RSI) is a terminology that refers to several variations of musculoskeletal muscle complaints. This involves a complaint known as muscle tenderness. RSI includes disorders of the upper arm related to Work-Related Upper Disorders and injuries to excessive use of Occupational Overuse Injuries.
Early symptoms of RSI can appear in various places from the base of the arm to the tip of the hand. Symptoms that become warning signs concern:

Difficulty opening and closing hands
Hand muscles feel stiff (for example, until it is difficult to fasten clothes)
Difficulty using hands (for turning pages of books, turning buttons, holding mugs)
Wake up with pain in the wrist or numbness in the hand, especially early in the morning
Hands feel cold
Trembling hands (Tremor)
Hands feel awkward, vibrate or even numb

Eye fatigue and headaches, are the complaints that most computer users complain about, Computer Vision Syndrome (CVS) itself is eye fatigue that can cause headaches, double vision, glare at night, and various other vision problems.

Asthenopia, which is the pupil of the eye, reacts slowly to light, because it is too long to be exposed to excessive light (can reach 75% -90% according to WHO reports).

2.3 How to Maintain Eyes to Avoid Monitor Radiation

Basically, it is very easy to prevent interference and also damage to the eyes due to computer. The following are some tips and also things you can do to prevent your eyes from being damaged by computer use:

Keep your eyes clear from the computer screen, at least 30 CM
Choose a monitor that has a high resolution
Lighting around the computer must be sufficient, don’t use a computer in a dark room
Eat foods that contain vitamin A
Limit the time to use a computer, not more than 3 hours full non-stop every day.
Take rest when your eyes feel heavy and tired

Health experts say, in everyday life everywhere there is electromagnetic wave radiation. So that everyone must be able to protect themselves in an initiative, but no need to feel too tense and frightened, even though due to electromagnetic waves can cause cancer and other diseases.

2.4 Impact of Monitor on Human Physicality

For the physical condition of man himself, the use of computers can of course have a negative impact, especially if the user or user of the computer does not comply with the rules of computer usage properly. Like how to sit, how to read and stare at computer screens, to excessive computer use.
One physical part that is often affected and also the danger of a computer is the eye, which is a visual part of a person. The eye is very closely related to the display or display of a computer. The following are some computer hazards to the eye:

Causes visual disturbances, such as minus eyes
Eyes become tired and experience dizziness
The eyes are red and sore
Sharpness of vision decreases

3.1 Conclusions

Monitor or with another term called VDU (Video Display Unit), is one of the most important parts of a computer unit. This monitor part is what we often see when we use a computer. In the use of computers there are radiation-screen monitors that can interfere with health.
