Surabaya Tempo used (STD) is a community that has an enthusiasm for history and local culture Surabaya. Founded on 10 November 2010 by Bambang Irawan through social sites Facebook.

The purpose of this community is simple, that is as a place to share and learn about the history, literature and culture. We, admin STD is not from a collection of historians, but from a variety of backgrounds who have the same interests. Here we just want to be a "bridge" for the general public who are interested in world history and culture without having to be experts in the field. We want to open the fog of history that had been stored in the book - the book to the public so it is easier to understand and interesting. So the end is a form of love and concern for the city of Surabaya, especially aspects of history and culture.
