Introduction The role of social media in political campaigns has become increasingly popular since Barack Obama successfully used Facebook as one of the main communication media to campaign during the presidential election in the United States in 2008 and proved by his victory he was elected President of the United States in 2008. General election candidates and politicians also began using various other social media platforms outside of Facebook, such as Twitter, Instagram, and Youtube. In Indonesia, in the 2012 DKI Regional elections, according to Andriadi [1] social media has a very significant role in building participatory communication and political branding of the Jokowi - Basuki pair, by seeing the high traffic of conversations about Jokowi - Basuki in social media, especially Twitter and Facebook. [1]Andriadi then added some interesting facts that social media is able to become a catalyst that amplifies the Jokowi - Basuki campaign into various social pockets. Social media becomes a new public sphere for the public to discuss politics. In addition, the marriage between offline activism and online supporters and volunteers of Jokowi - Basuki representing actual participatory democracy.

It can be concluded from a number of explanations above that the use of social media has become a very important element in political campaigns, especially at this time that the level of use is increasingly high and more and more forms of social media. Furthermore, the 2017 DKI Regional elections is present amidst the high level of social media activities by the community, of which 132 million internet users are in Indonesia, 40% of whom are social media users (www.detik.com, 2017).
