Development of the world today is certainly not out of the current development of communications technology is growing by leaps and bounds. Since the development of this fast growing world, it takes the ability to access information quickly. Starting from the print media, through electronic media. This development is seen especially in electronic media, where one important factor that was instrumental in the development of electronic media today is the internet.

With the Internet people can very easily exchange information using electronic media, such as PC (Personal Computer) or with mobile devices, such as mobile phones, and tablet PCs. Due to the increasing number of people who exchange information via the Internet, it will need to communicate the necessary security. Because of this it is necessary to be a way to transmit data securely. One way is by using concealment on the data before the data is transmitted.

In this paper, we discuss the design of hiding or steganography messages on the image by using the method applied to mobile devices. F5 algorithm is one of many algorithms used in the purpose of steganography in JPEG images. Steganography applications are built using the Java programming language Android.

Based on the design and implementation has been done, we got the result image is not much different from the original image. So that the security of data sent using the application program is assured. Based on the error checking using the PSNR obtained good results for each image steganogram, that is more than 70 dB.
