With the development of information technology in particular in the field of multimedia in such rapid and the longer forms of media information more diverse so that more education institutions boast. Media information and promotion is currently used by SMK PGRI 11 Ciledug Tangerang. The purpose of this research audio visual media into the media information and proper promotion, by controlling hearing and vision in the form of audio visual in order to convey messages can be understood by the public at large. Existing problems, namely the medium used by the SMK PGRI 11 Ciledug Tangerang still use print media such as banners, posters and pamplet are considered less effective and efficient to use while simultaneously promoting the institutions with the best possible audio visual media so that it is selected into a medium of information and promotion of the right, by controlling hearing and vision in the form of audio visual. Because therein lies the message delivery process or how to visualize. At the same time listening and showing the contents of the message to the recipient with information through media menunjangnya, so the design of video media profile that displays the entire scope, advantages and facilities belonging to SMK PGRI 11 Ciledug Tangerang, can be a solution in solving problems in media promotion and information. With this study the author makes with the title "promotion and INFORMATION AUDIO VISUAL MEDIA SHAPED VIDEO PROFILE on SMK PGRI 11 APPLICATIONS TANGERANG CITY ".

Communication via sockets is used to transmit information between applications or between processes over network or locally. ZeroMQ is a library for sending messages using sockets that are quite well known. Talking about sending data, message security is an important part that needs to be taken into account, especially when sending data over a network. ZeroMQ sends messages openly without securing the messages sent. This is evidenced by research which states that ZeroMQ does not have a security layer for sending messages over the network and direct observation of message packets using the wireshark application. Therefore, this study creates a method of securing and authenticating message delivery using AES (Advanced Encryption Standard) CBC (Cipher Block Chaining) mode combined with an authentication method. The AES CBC mode was chosen because it is faster than other methods and has strong encryption. This encryption and authentication are used so that the sender and recipient of the message are both valid senders and recipients so that no message changes during message delivery and messages can only be opened by the message recipient and the sender of the message. Tests are conducted to measure the effect of encryption and authentication on message delivery performance. Based on the tests conducted, there is an increase of 7% from normal delivery speed and the potential for messages is not up to 0.3% - 1.5%.

Constant Internet connectivity has become a necessity in our lives. Hence, music festival organizers allocate part of their budget for temporary Wi-Fi equipment in order to sustain the high network traffic generated in such a small geographical area, but this naturally leads to high costs that need to be decreased. Thus, in this paper, we propose a solution that can help offload some of that traffic to an opportunistic network created with the attendees’ smartphones, therefore minimizing the costs of the temporary network infrastructure. Using a music festival-based mobility model that we propose and analyze, we introduce two routing algorithms which can enable end-to-end message delivery between participants. The key factors for high performance are social metrics and limiting the number of message copies at any given time. We show that the proposed solutions are able to offer high delivery rates and low delivery delays for various scenarios at a music festival.
