communicate during social and political protests can
potentially upset the status quo by changing policies
or causing structural changes. The Arab Spring in
2011 was an example of a regime's demise due to
social media encouragement (Tufekci, 2017) by
allowing for public involvement, which social media
aids movements are calling for political change (Lim,
2012). As a media tool, Twitter disseminates general
information acquired by the community and most
impact political change via opinion formation
through a hash mark (#hashtag), which canonicalize
the subject, concentrate on themes, and assist
internet-based search engines (Syahputra, 2017).
From here, the dominance of online political
discourse on social media, more or less influenced by
the resources owned by each political party. Thus, it
is not surprising that political figures from major
political parties often dominate political discussions
online or on social media (Klinger, 2013).
2.2 Algorithm and Polarization
In general, three aspects become the main focus of
research in the parties/candidate's category: the
characteristics of political parties or candidates who
use Twitter as a political medium, how they use
Twitter as a political medium, and the effectiveness
of using Twitter as a political communication tool by
them (Jungherr, 2016). Moreover, Twitter is used by
politicians to produces a high buzz effect that the
mainstream media can amplify. In this case, tweets
are more of a reactive action and not a tool to predict
the contest (Murthy et al., 2015). Twitter becomes a
location that is regarded as the most appropriate for
gossiping even in cyberspace due to the social aspects
of people who want to gather and talk, debating
rumors or problems (Pohjonen & Udapa, 2017). The
gossip arena in cyberspace sometimes turns into war.
For instance, Twitter accounts affiliated with
presidential candidates such as @GarudaPrabowo,
@Gerindra, @Jokowi4me, @PDI_Perjuangan,
@Relawan_Jokowi, @FansGerindra, and other
accounts are often seen debating online (twitwar).
Not to mention communally managed accounts like
@PartaiSosmed, @99army, @Triomacan2000, who
are part of the campaign interests of the presidential
candidates, are often involved in twitwar defending
their presidential candidate. Hashtags are in close
relation to an algorithm. In simple terms, the
algorithm works in two stages: (1) knowing tastes and
preferences of social media account owners which
data can be found from various activities on social
media such as clicking, searching, or share social
media content to provide content according to your
sense of humor, liking, phobias, and even sexual
tendencies, and (2) the algorithm engine works by
classifying people who have in common: tastes,
ideologies, phobias, and so on.
Simply put, like-minded ideologies and tastes are
put together. The existence of traditional propaganda
containing lies and misinformation spread online is
powered by social media, in this case, Twitter
algorithms (Woolley & Howard, 2018). Further, lack
of control and ambiguity about algorithmic
assessment may create algorithmic anxiety as
individuals are labeled and categorized by the
machine (Jhaver et al., 2018). Another negative
consequence of an algorithm is the Filter Bubble that
separates a person through personalization which
may undermine the internet's initial function as an
open platform for exchanging ideas, leaving us all in
an isolated, echoing world. The filter bubble also
creates a false consensus effect; that is, a person tends
to claim that others agree with him, and conclude his
opinion is the majority's conclusion (Pariser, 2011).
The harmful effects of filter bubbles are getting worse
due to the bad habits of netizens and media. The
media likes to make bombastic titles (clickbait), and
netizen's practices to share content without thorough
reading played a role in the enormous effect of this
bubble.
2.3 Buzzer Activity
Buzzer activity in Indonesia began to be used in 2009
for promotional interests. Buzzer involvement in
political events started used in 2012 during the
political contestation of the DKI Jakarta Pilkada. On
2014 presidential election, the use of buzzers is
increasingly being used in the political arena 2014
Presidential Election. Buzzer involvement in political
campaigns has contributed negatively to the image
and the meaning of society towards the buzzer.
Buzzers produced negative content and even hoaxes
on social media (Camil et al., 2017). Even after the
Reformation Order, the internet is still seen as one of
the media over which the government has little
influence in terms of social and political problems
(Setianto, 2015).
2.3.1 Types of Buzzers
Based on the motive (Camil et al., 2017), buzzer can
be divided into three, namely: (1) professional
commercial buzzer, which indicated by the flow of
funds, motives are purely for money and has nothing
to do with ideological or personal principles, also
have good command technical and reading skills
