that they became bonded in an informal network, and 
in due course picked up a collective identity. Tarrow, 
one  of  the  first  political  scientists  to  recognize  the 
relevance  of  social  movements  as  political  actors 
(della  Porta,  1995),  defined  social  movements  as 
"collective  challenges,  based  on  common  purposes 
and  social  solidarities,  in  sustained  interaction  with 
elites, opponents, and authorities” (Tarrow, 2011). 
Tarrow  (2011)  basically  considered  collective 
challenge  as  an  action  by  a  group  of  people  to 
challenge an opponent group. Social movements use 
collective  challenge  as  the  main  supporting  points, 
attracting the opponent and third-party attention, and 
creating a constituent for representing it (Can, 2014; 
Sunoto,  1994;  Tarrow,  2011;  Willet,  2013). 
Furthermore,  collective  challenge  has  often  been 
shown  through  the  disruption  over  people  activities 
and on the governance level, it can be symbolized by 
a slogan, dress code, or by giving a new name to an 
object with a new symbol (Tarrow, 2011). 
Common  purpose  is  a  goal  that  group  members 
wanted to achieve, which in turn provided a common 
reason  for  people  to  join  a  movement,  such  as  to 
collect common claim against a perceived enemy, the 
authority, or the elites (Tarrow, 2011). Even though, 
organization  or  group  with  certain  interest  will 
encourage people to join a movement, not all conflict 
emerged  because  of  group  interest.  Sometimes  a 
feeling  of  having  common  or  overlapping  interest 
provided  a  reason  for  people  to  act  and  join  it 
(Gamson as cited in Baron, 2013). On the other hand, 
people will not sacrifice their resources and take a risk 
to become  involved in a  movement without a  good 
reason (Can, 2014; Tarrow, 2011; Willet, 2013). 
Solidarity  in  social  movement  is  an 
acknowledgment  of  common  interest  which  then 
changes as a potential to act in a movement (Tarrow, 
2011).  One  of  the  forms  of  social  solidarity  in  a 
community is the willingness of its member to help 
other  members  whenever  assistance  is  needed 
(Durkheim as cited in Can, 2014). On the other hand, 
group  identity  shows  the  willingness  and 
responsibility  of  the  group  members  to  encourage 
people to participate in  a  social movement (Polletta 
and Jasper, 2001). 
Social  interaction  is  a  general  process  whereby 
two or more people involved in meaningful contact, 
resulting in modified behavior (Elredge and Merril as 
cited in Muhammad, 2011). For a social interaction to 
happen, two things must be present - communication 
and social contact (Gillin and Gillin as cited in Baboe, 
2016).  Collective  action  will  turn  into  a  social 
movement when a controversial issue is maintained, 
hence  the  interaction  between  the  movement 
participants and the opponent must also be sustained 
(Tarrow,  2011).  While  the  interaction  between  the 
parties involved could happen indirectly, say through 
social  media  (Lim,  2005;  Lim,  2017),  direct 
interaction is also needed to facilitate it (Matthiesen, 
2012). 
Based  on  Tarrow’s  theory  of  social  movement, 
this study proposed the following hypotheses:  
H1: Collective challenge has a positive effect on 
participation in the ‘411-212’ movement in 
Jakarta 
H2: Social  solidarity  has  a  positive  effect  on 
participation in the ‘411-212’ movement in 
Jakarta 
H3: Common  purpose  has  a  positive  effect  on 
participation in the ‘411-212’ movement in 
Jakarta 
H4: Sustained interaction has a positive effect on 
participation in the ‘411-212’ movement in 
Jakarta 
3  RESEARCH METHODOLOGY 
This  study  is  based  on  a  quantitative  method  with 
additional qualitative  data,  and  the quantitative data 
were  collected  using  a  questionnaire  which  was 
created  from  Tarrow’s  social  movement  theory. 
Participants were asked to indicate their agreements 
for each of the items based on a five-point Likert-type 
scale,  ranging  from  1  (“strongly disagree”)  to  5 
(“strongly agree”). The measure was grouped into the 
four factors of Tarrow’s theory, which are collective 
challenge,  common  purpose,  social  solidarity  and 
sustained  interaction.  Sample  questions  for  each 
dimension  included,  “I carry poster to show that I 
support the issues that we are fighting for,” “I must 
protest government authorities who do not act upon 
the mistake of public officials,”  ”As a religious 
person, I should participate in acts that defend my 
religion,” and “I join a social media group to follow 
the issues related with my group.”  Prior to the study, 
reliability  testing  was  assessed  against  46  former 
participants  of  the  ‘411-212’  movement  for  each 
social movement factor and items with low reliability 
were deleted from the scale, leaving 57 items that can 
be  used  for  the  study.  Alpha  Cronbach  were  as 
follows:  collective  challenge  (α  =  0.79),  common 
purpose (α = 0.76), social solidarity (α = 0.68), and 
sustained interaction (α = 0.72). Total Alpha score for 
the entire scale was 0.89. 
Using criterion random sampling technique, 300 
participants  (128  women  and  117  men)  who  are
