3.2.1 Physical Condition
This first aspect is an obligation for a referee and an
assistant referee  before they will be  on  duty. They
must pass a physical test before the competition, if
they do not pass the physical test then they are not
allowed to lead a match. In the Indonesian league, any
referee who will be involved in the competition must
follow  referees  conducted  by  PSSI,  every  referee
must  follow  the  activity  if they  want to  serve  in
League 1 Indonesia. The function of physical ability
itself  in  the  performance  of  the  referee  is  that  the
referee must always move in the game and strive to
always close to the event so that the decision given
will be accurate, besides the referee and the assistant
referee must always move in a match following the
game  and  asked  not  far  from  the incident. (Mallo,
Navarro,  Garcia-Aranda, and Helsen,  2009).  The
referee must find the right point of view to decide an
event, so the referee must be strived to move if his
position is obstructed. For the assistant referee in the
offside determination, the assistant referee must have
a good point of view between parallel to the last two
defenders, following where the ball will be played,
where the starting position of the attacker will touch
the ball and where the ball will be played (Catteeuw
et al: 2010). In the author's observation of the position
of the referee in every decision, especially when the
counterattack is very far from the event that resulted
in  the  decision becomes doubt.  In  addition  to  the
assistant referee  is  often  left  behind or not aligned
with the last two defenders, although the decision is
true, and the assistant referee who was too hasty in
deciding an event, but who will control the ball is a
player who is not in an offside position. This becomes
an issue  that  must  be  fixed  by  Indonesian  football
organizations.
3.2.2 Psychological
In psychological terms it is associated with a threat to
referees that occur before, during, and after the game.
In  this  case  the threat that  is often  experienced  by
football  referees  in  Indonesia  is  the  presence  of  a
pressure from the audience, players, and official. A
referee  who  has  experienced  a  threat  will  affect
psychological,  concentration,  performance,  and
motivation  so  that  the  decisions  taken  will  be
inaccurate.  (Coakley,  1994).  A  threat  or  pressure
experienced by the referee is divided into two forms:
physical and verbal, (Folkesson, Nyberg, Archer, and
Norlander, 2002). Many improvements made by PSSI
and the opponents  of the New Indonesia league  to
anticipate the threat factor made by players, coaches,
managers,  and  also  the  audience  to  referees  and
assistant referees, namely by issuing strict rules on
threats to referees, the result is in Liga 1 Indonesia
decreasing  the  level  of  physical  threats  made  by
players, coaches, official and spectators to the referee.
But  verbal  threats  are  still  often  experienced  by
referees, both from players, coaches, and spectators.
In addition to the existence of an external threat, the
motivation  in  the  self  affects  the  referee  itself,  a
referee who has his own desire to become a referee
will have better self-control, compared to the referee
who is motivated because of their economic factors
will  be  forced  in  duty  and  will  even  affect its
performance (Dohmen, 2008).
Understanding the rules of the game is a must for
a referee, how an umpire will decide a problem if he
does not control the rules. Football rules every year
there  is always  a  change,  so  referees  and  assistant
referees should always update the latest regulations.
Regarding  this  understanding,  not  only  the  referee
who must master, but the coach, players, spectators
must master and know the rules that apply, so that
there will be mutual respect between professions. One
study says that the understanding of the rules of game
players,  coaches,  spectators,  media  and  related
components of football is very low (Gilis, B., Helsen,
W., Catteeuw, P., Van Roie, E., and Wagemans, J.
2009 ).
4 CONCLUSIONS
From the results of the research that has been done, it
can be concluded that the decision of the referee in
leading football match in Liga 1 Indonesia on article
12 or violation and unsportsmanlike behavior has a
relatively small bias value, while the assistant referee
on article 11 or offside obtained the very low score of
bias.
