individual  test  obtained  value  Py1  =  0.305  means 
probability value Py1 = 0.305>.005 at level a = .05. 
Second, along with the findings, also found positive 
influence between bureaucratic leadership style (X2) 
on teacher work motivation (Y) based on individual 
test  calculation  obtained  value  Py2  =  0.4406  mean 
probability  value  Py2  =  0.4406>0.05  at  level  a  = 
0.05.  Third,  the  study  found  a  positive  influence 
between  democratic  leadership  style  (X1)  and 
bureaucratic leadership style (X2) simultaneously on 
teacher  work  motivation  (Y)  expressed  in  terms  of 
regression  equation  Y  =  47.065  +  0.342  X1  + 
0.141X2. 
According to the results of the research, there are 
at  least  seven  indicators  that  indicate  the  weakness 
of  teacher's  work  motivation  in  carrying  out  their 
main  task  (teaching)  they  are:  (1)  Low 
understanding  of  learning  strategy;  (2)  Lack  of 
proficiency  in  classroom  management;  (3) 
Insufficient ability to conduct and utilize Classroom 
Action  Research;  (4)  Low  achievement  motivation; 
(5)  Lack  of  discipline;  (6)  Low  professional 
commitment  and  (7)  Low  time  management 
capability. 
Similarly,  what  happened  in  SMA  Negeri  1 
Dolok  Batu  Naggar  resulted  in  low  teacher 
performance  among  others  is  caused  by:  1)  There 
are  still  many  teachers  who  do  not  pursue  the 
profession as a whole. This are the cause of by some 
teachers  who  learn  outside  working  hours  to  meet 
the needs  of  everyday  life,  so they do  not  have  the 
opportunity  to  improve  themselves,  like  read,  write 
and learnt from book or internet. 2) The absence of 
professional  standards  of  teachers  as  demands  in 
developed countries. 3) some private university that 
produced haphazard teacher, or unprepared, without 
considering  their  output  in  the  field,  causing  many 
teachers  who  are  not  obedient  to  their  professional 
ethics. 4) Lack of teachers’ motivation in improving 
quality because teachers are not required to research 
as applied to lecturers in universities. 
Based on these conditions, there are at least two 
categories  of competencies  that  the teachers  should 
have, namely: 
1.  Professional  competence  is  the  ability  to 
design,  implement  and  assess  the  task  as  a 
teacher,  which  includes  mastery  of  science 
and technology education. 
2.  Personal  competence  that  includes  ethics, 
morals, devotion, social and spiritual ability. 
To be professional, a teacher is required to have 
at least five things as follows: 
1.  Having a commitment to learners and 
learning process. 
2.  Mastering  in-depth  the  materials/subjects 
taught and how to teach it to learners. 
3.  Responsible  fthe  learning  outcomes  of 
learners through various ways of evaluation. 
4.  Beingable to think systematically about what 
it does and learn from the experience. 
5.  Being  apart  of  the  learning  community  in 
their professional environment. 
Teachers  as  one  component  in  teaching  and 
learning  activities  (KBM),  has  a  very  decisive 
position  on  the  success  of  learning.  Because  the 
main  function  of  the  teacher  is  to  design,  manage, 
implement  and  evaluate  learning.  In  addition,  the 
position  of  teachers  in  teaching  and  learning 
activities  is  also  very  strategic  and  decisive.  It  is 
strategic  because  the  teacher  will  determine  the 
depth  and  breadth of  the subject  matter,  while  it  is 
decisive  because  the  teacher  who  chooses  and  sort 
the  lesson  material  that  will  be  presented  to  the 
students.  One  of  the  factors  that  influence  the 
success  of  the  teacher's  task  is  the  performance  in 
planning/designing,  implementing  and  evaluating 
the teaching and learning process. 
According to Suparlan the function of teachers in 
teaching and learning process is as educator, teacher, 
mentor, and as coach (Suparlan, 2005). 
Teachers must have  a good  performance  so  that 
their duties and responsibilities can be implemented 
properly.  Performance  is  a  visible  attainment  or 
achieved  performance  (Badudu,  2006).  In  order  to 
produce  a  good  performance,  a  teacher  must  have 
the  ability,  willingness,  and  effort  in  teaching  and 
learning process  that  includes  planning, organizing, 
implementation,  and  evaluation  of  learning 
outcomes.  Teachers’  performance  related  to  work 
motivation, performance and productivity. 
SMA  Negeri  1  Dolok  Batu  Nanggar  is  an 
educational  institution  that  struggles  to  educate  the 
children  in  nationto  succeed  the  national 
development goals  of  Indonesia. With a democratic 
leadership  style  and  bureaucratic  leadership  that  is 
still  low  resulted  in  teacher’work  motivation  needs 
to  be  considered.  Democratic  and  bureaucratic 
leadership  is  the  style  or  type  of  leadership  of  a 
person  who  try  to  place  human  beings  as  the main 
and  most  important  factor  in  improving  teachers’ 
performance  and  solving  various  problems  that 
occur in a bureaucracy in certain situations.
