Abstract

Rapid development of current computer technology often lead to abuse of the technology in a criminal action. One of the most common is the theft of the Password (password), personal accounts until confidential documents. To that end, the perceived need for a form of safeguard against the things above in order to comfort the user in using computer technology. Encryption is one method to randomize the words so that it cannot be read and understood by anyone else except by users who use them and those who were given the right to use it. The Kerberos method is a method of encryption that originally applied to secure a computer network. Kerberos authentication works by comparing input data with the given keywords. Based on the workings of the Kerberos method, be designed a device for data security in the form of a text message is converted into the form of a digital image. Through the processing of Binary value from the message text inputed. will be generated a digital image is the result of a binary-binary encryption of text messages through the Kerberos method. This type of data security is more secure than cryptography that produce the same output with the Plaintext, such as cryptographic text messages that generate output in the form of a digital berbedayaitucitra denganbentuk message.Keywords:  Cryptography, Kerberos, Conversion, Digital Image

Abstract

ABSTRACTInfectious diseases known as infectious diseases are a disease caused by a biological agent (such as viruses, bacteria or parasites), which can be transmitted or transmitted to others through certain media such as air, food and drink that are less clean , syringes and blood transfusions and direct contact with the patient. The expert system is one of the branches of Artificial Intelligence that makes extensive use of knowledge, especially for the expert-level problem-solving. Bayes is a simple probabilistic based prediction technique based on bayes rules. The goal to be achieved is to create a useful expert system application as a tool to get information on infectious diseases in infants.

Abstract

Basically, confidential data needs to be stored or delivered in a certain way so as not to be known by unauthorized foreign parties. And to overcome the problem then created the science of cryptography and steganography. One example of a cryptographic algorithm is the Rivest Code 4 (RC4) algorithm, and one example of the steganographic algorithm is End Of File (EOF). Cryptographic algorithms can be combined with steganographic algorithms so that the secret messages we have are more secure than foreign interference. First of all secret messages that we have first encrypted using the Rivest Code 4 (RC4) algorithm, then the encrypted ciphertext is hidden / inserted in the image / image media with the End Of File (EOF) steganography method.Keyword: Kriptografi, steganografi, rivest code 4, end of file, cipherteks

Abstract

English is a universal language that is important and has a big role in the world of gaming. Therefore, in order to make children learn English in activities they like. An educational game was made, educational games were built aiming to improve children's ability in terms of English. This game is also designed based on Android so that it makes it easier for players to access games without the need for an internet network to play. In programming, this game implements Fisher Yates algorithm to do the randomization process in the game. The Fisher Yates algorithm is an algorithm for generating a random permutation from a finite set, in other words to randomize a set. This game is played by a player, to complete each level of the game, with the higher level of the game will also increase the level of difficulty. Using a database with SQLite to store player names, questions and levels that have been achieved.
