For those reason, simulation techonology has been created.Learning media which created in this thesis based on looped animation and interactive system that purposed on assisting student to learn chemist in interactive module. Application designed for four chemist lesson which implemented in simulation, several quiz and games. Mixture lesson displayed in interactive simulation that student can try some simple experiment. Atom’s model, Periodic Table and Chemical bond displayed in interactive media that encourage student to explore the content of lesson themselves.Test result shown that the application is able to help student to learn chemist theory. Three part of application give adequate lesson for student and a part of application need more improvement.

Augmented Reality itself allows users to interact in real-time with the system. Augmented Reality is widely used in various things, for example in the field of entertainment, advertising and also used in the games. But of the many games in circulation, there are still few games that use Augmented Reality as the main key in the game.Tower defense games have the primary purpose of protecting a base from being reached by enemies running on predetermined paths by constructing tower placements. By using augmented reality, user can play the game through various viewpoints in accordance with the movement of the camera on the android device that leads to the marker so that it will increase the interaction between players with the game.Through testing can be proven that the use of Vuforia’s Augmented Reality can be used for game development because it can provide good results.

No doubt that any confidential information sent over the Internet. Through various types of information is developing techniques for damage or maintaining the security of the dissemination of information on the internet.Securing data by using cryptography is needed for sending confidential data so that not everyone can access it. Process undertaken in this study is encrypted messages with MARS method. Input in an application that is designed in the form of plaintext messages or files to be encrypted, then the key to encrypt the message. This application is made with the Java programming language using NetBeans IDE 7.4.The test results indicate that the encryption with MARS method can be performed on any type of file (example: text file, song or audio file, video file or movie, etc.). Files can be decrypted back to normal if the password is the same as the password for the encryption.
