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.).

Abstract

Until now there are still many people who do not know how to improve, and how to care for them. LPG in homes. Therefore we need a tool that can tell through the application if there is an accurate and fast LPG gas leak.Arduino and applications are made using LPG gas based on PPM levels in LPG tubes, and can also use LPG tube temperature and humidity that change suddenly in a certain period of time. If a leak occurs, the gas application will immediately notify you of the LPG leak.Based on the results of testing that has been done, Arduino can protect gas leaks through PPM levels and can also protect gas leakage through temperature and humidity. Arduino can also directly turn off LPG gas by turning the regulator knob to the off position. Arduino and applications can run properly according to their functions. The application can also provide notifications in the event of a gas leak.
