YOGYAKARTA - Sandi is a secret communication system that has been used since ancient times. The basic principle is to turn original messages into encrypted messages that cannot be understood by parties outside certain groups.

In Scouts, code is used as a means of communication. When the distance is sufficiently far apart or in different locations it is not possible to communicate directly. Instead, a password is used.

In addition, code is also part of face education for logical thinking skills, problem solving, and teamwork. Therefore these passwords are often used as games and competitions in Scout activities. Here are 17 types of Scout code that its members must know and understand.

Morse passwords use a combination of points (.) and lines (-) to represent letters, numbers, or read marks. The system was discovered by Samuel Morse and was originally used in the telegraph.

In Scouting activities, Morse is usually practiced using whistles, flashlights, or tapping on certain surfaces. For example, the letter A is symbolized as a point-line (.-), while B is a point-point (-...). Familiar members will be able to read Morse messages in seconds.

Semaphore takes advantage of the two small flags held in hand, each leading to a certain corner to represent letters. Each hand position has a specific meaning according to the international code. Semaphore is usually used during the day in open fields.

Its use requires good eye and hand coordination exercises. For example, the position of the flag at 12 and 4 o'clock symbolizes the letter U, while at 2 and 8 o'clock it represents the letter 'K'. In the competition, participants are often asked to send complete sentences only with this movement.

Cipher box or Box passwords compile letters in the form of boxes or tables, typically 5times5. Each letter has certain coordinates based on rows and columns. The recipient of the message will use the same table to interpret messages.

For example, the letter B is in the first row of the second column, so it can be represented by 12. This system is simple but effective if the sender and recipient have agreed on the key.

In this password, letters are replaced with numbers according to the alphabet sequence, for example A=1, B=2, to Z=26. The message will be in the form of a row of numbers, which then converted back into letters.

For example, the 'PRAMUKA' message can be written as 16-18-1-13-21-11-1. Number passwords are often used as initial introductions before studying more complex codes.

Named by Julius Caesar who used it in military communications, this code shifted letters several steps in the alphabet. For example, sliding three steps: A to D, B to E.

The 'PRAMUKA' message by sliding 3 into SUDPXND. The key in the form of the number of sliding steps must be known by the recipient to be able to read it.

This password compiles messages vertically or horizontally in a table, then reads them differently. This technique makes messages difficult to guess because the composition of letters does not follow the natural pattern of the language.

Usually used tables with a certain number of columns. For example, the message is compiled per column, then reads it per row.

Number Password is the easiest to understand code, where each letter is represented by numbers according to the alphabet sequence (A=1, B=2, and beyond). This password is often used as the basis for encryption and decryption exercises.

Binary Sandi uses a combination of numbers 0 and 1 to represent each letter. For example, letter A can be represented by binary code 010000001. This password is the foundation of digital communication and modern computing systems.

Password Password is a code system that relies on touch. Each letter and character is changed to a combination of points arising. To encrypt messages, you turn letters into titiks.

Meanwhile, to decrypt, you touch these points and match them with aID table. This password requires touch sensitivity and understanding of the rotary system.

AZ passwords are simple substitution codes where each letter is replaced by the opposite letters in alphabet sequence. For example, A is replaced by Z, B by Y, and so on. Although easy to study, these codes are also easy to solve.

Sandi Rambu uses symbols of traffic signs or public signs to send messages. Each sign has a special meaning that must be translated into a complete message.

Sandi Kimia combines science knowledge and encryption. This password uses the symbols of chemical elements from the periodic table to replace letters. For example, H (Hydrogen) can represent the letters H, O (Oxygen) for the letters O, and so on.

Sandi Jam uses time on the clock as a code. For example, at 06.00 it represents the letter A. Then, each subsequent letter is represented by an additional time of 5 or 10 minutes. For example, if the time difference is 5 minutes, then at 06.05 it will represent the letter B.

This password uses hand or finger movements to form letters and words. Generally adapted from the deaf sign language. In Scouts, this code is used when conditions demand silent or silent communication.

Trace passwords use signs from stone, twigs, lime, or soil to show a specific direction or message. Signs can be in the form of arrows, circles, or cross marks. Useful in natural cruising activities to provide clues to other groups.

Unlike the semaphore, flag code relies on a combination of colors or flag positions as a specific sign. Usually used for remote signals on open fields. Its use is often seen in scouting games to send voiceless fast commands.

The letter password replaces the letters in the message with other letters according to a certain pattern. The popular pattern is to reverse the alphabet sequence (A=Z, B=Y, dst.). For example, the word PRAMUKA if using the alphabet's reversal to KIZNFPZ. This technique is simple but quite confusing for those who don't know the pattern.
