the individual because the concept of self determines
how individuals act in various situations (Calhoun &
Acoccela, 1990).
The results of research conducted by Rola (2006)
showed a significant relationship between self-
concept and achievement motivation in adolescents.
The same research conducted by Gage & Barliner (in
Rola, 2006) shows that there is a positive relationship
between self-concept and the desire for achievement.
Also, Wulandari & Rola's (2004) research on the
relationship of self-concept and achievement
motivation for adolescents who live in orphanages in
Medan City, shows the role of self-concept on
achievement motivation is very large or significant.
The results of the study conducted by Latifah (2018)
also showed that self-concept significantly affected
students' achievement motivation with a contribution
of 33.26%.
2 LITERATURE REVIEW
2.1 Achievement Motivation
According to Mc Clelland in Djiwandono (2008),
Achievement motivation is where a person tends to
struggle to achieve success or choose an activity that
is oriented to success or failure goals. Thus the
achievement motivation comes from within the
individual and not from others so that success in
learning can be achieved. Achievement motivation is
a very important role in achieving success because a
person's success is achieved due to self-motivation, so
that good learning outcome is achieved.
According to Sri Esti (2009), Motivation has
intensity and direction. The intensity of motivation
used for an activity may depend on the magnitude of
the intensity rather than the magnitude of the
direction.
Achievement motivation that is owned by one
person with another certainly different. Several
aspects are used as a measure of high achievement
motivation. This was revealed by McClelland (Rola,
2006) that there are six characteristics of someone
who has a high achievement motivation, among
others.
a. A strong feeling to achieve goals, namely the
desire to complete the task with the best results.
b. Responsible, which can take responsibility for
himself and determine his future, so that what is
said is successfully achieved.

person's self-concept is influenced by several factors
as follows.

experiences, that give rise to positive feelings
and valuable feelings.
b. Competence in an area that is valued by
someone and others.
