With the more popular multimedia world, security are the main concern at this time. Data theft occurred in popularity virtual world (internet). One important issue is the level of information security. This can be done by using encryption or steganography. Steganography is a method to insert a snippet of information in a confidential other multimedia object. In the data hiding, steganography or data hiding embedding the data seems very familiar with the encryption. However, data hiding by changing the order of characters in a multimedia same. While in steganography, data hiding is done in a way to change or shift some of the information that is not visible in the media of important message. The proposed methods in this paper are Least Significant Bit (LSB) and Low Bit Encoding (LBE). These methods will be applied to the message which is inserted into multimedia images (bmp, jpeg), audio (wav, mpeg), and other files (exe, pdf). Share media with the image data entered in the frame, this technique is expected to be able to insert information in a single frame maximum of 1 bit, so changes are not visible light. Method end of the project is proving a secret message hiding techniques in multimedia. Result output file generated by this scientific report changes in the quality of which is the lower of the original file. In the comparison of image files, image files which have experienced steganography will be look brighter if due to changes in contrast. While the comparison of media files, media files which have experienced will have been damaged in audio, there is little noise in the audio. Then the last is a pdf or exe files, if the file has steganography, the file size will be changed in size due to a significant size of the file is added to the original size of the message to be hidden.
