Introduction
Teachers are considered as the main determinant of the success of a school, Edmonds (1979), Mahmood (1993); Miller (1982) believes the headmasters leadership is the most important determinant of excellence the school.As the highest leader in the school, the headmasters should be able to manage all elements of the school, dividing their time well in school management, both for its own tasks as well as for the school as a whole, teaching and learning activities can be carried out efficiently and effectively.The main role of the headmasters in the school is to provide instructional leadership to teachers, headmasters should be able to give a good impression to motivate teachers in carrying out their duties effectively so that their performance will be better.Mulyasa (2007) states in a new paradigm of educational management, headmasters in school should at least be able to play the role of Educator, Manager, Administrator, Supervisor, Leader, Innovator, Motivator.
Lane and Walberg explained, "As the leader in the school, the principal plays a major role in initiating activities and in facilitating or assisting with the follow-through.The degree to which the principal attends to these tasks will determine school success" (Cotton, 2003).Stronge in the Cotton (2003) concluded that to obtain good results of student achievement need to a dramatic change in the role of a headmasters who focus on managerial issues and principals who focus on issues of instructional.
The headmasters had a role in the process of designing, preparing, implementing, directing and leading the solidarity and unity of all programs and included all power sources to achieve the goals set.As a manager, the headmasters with ingenuity and intelligence which is owned to find and use a variety of activities interrelated to achieve objectives (Mulyasa, 2003).Instructional leadership is an act done with the intent to influence the headmaster, move, and develop a work environment that is productive and useful for teachers, and ultimately to create good conditions in improved the student learning.
The existence of a good headmaster leadership and work discipline of teachers as educators can be generate high work motivation of teachers in apply their learning in school, improve academic achievement seen from the quality of the learning process in schools, akademic achievement in schools can be improved because of the headmaster leadership and work discipline shown by the teacher a good teacher.
In education, teachers are one of the most important to the success of education in schools, because the teacher to have sufficient performance to produce students who can be trusted and quality.Teachers are have an active role in the learning process for the formation of human resources (Sardiman, 2001).Teachers as a supervisor for student success are required to play a more active role in achieving educational goals, namely: to develop students' potential, to become a man faithful to God, noble, knowledgeable, skilled, creative people, free and become a democratic and accountable (Law of the Republic of Indonesia, 2003).Professional teachers will be reflected in the implementation of teaching tasks that are marked with expertise in teaching management and labor contribution.Expertise of a professional teacher is a skill acquired through education and training specifically programmed for that.The skills of gained from official recognition in the form of certification, accreditation, and licenses the government and professional organizations.With the expertise of teachers can demonstrate autonomy, either as a personal or stakeholder profession, as one of the characteristics of a professional teacher is a teacher who has the discipline in the use of time.
By Sukadi (2006) there were eight personality bad teachers are often found in schools, indicating that the work is not yet effective teachers, namely: (1) often leave the classroom, (2) do not respect the students, (3) lack of preparation in learning, (4) favoritism to students, (5) asked students to write on the board, (6) no discipline, (7) lack of attention to students, (8) materialistic.
Teachers who have a good quality of work stems from discipline in carrying out their duties and responsibilities as an educator, teacher discipline become one of the important things that need to be owned by a teacher as an educator, the teacher self-discipline is a personal reflection of a teacher, a teacher who has a high discipline will provide clear evidence of the nature and quality of the teacher.Sastrohadiwiryo (2003) states that the discipline of work can be defined as an attitude of honor, respect, obey and adhere to the regulations in force in both written and unwritten, and is able to run and not to avoid punishment if they violate the duties and powers conferred on him.Teachers who have a high level of discipline will continue to work well even without supervision by superiors.Maintain good discipline to teachers is very difficult, it is because many indicators that affect the discipline, as expressed Fathoni, (2006) that disciplined indicators, namely: the purpose and capabilities, leadership by example, reward, justice, control, criminal sanctions, firmness, regulatory and human relations.Suharto and cahyono (2005) and Hakim (2006) states that there is one factor that affects performance is the motivation, the motivation is a condition in which a person who engages or attempts to achieve desirable results.Rivai (2004) shows that the the stronger of motivation, employee performance will be higher.This means that any increase in employee motivation will provide significant improvements to enhance the performance of the employee to do the job.So that academic achievement in school can be done well.
The academic achievement in the learning process in schools, depends on the quality of teaching and school leadership, especially the quality of teachers.Wildy and Dimmock (1993) says that the research on principals' leadership in teaching activities most countries found that principals who have teaching skills in leadership can make a difference in teaching and student learning.
Academic achievement in elementary school in Jakarta can not be achieved if the headmaster leadership in instructional leadership, discipline and motivation of low in school, will trigger a decline in the quality of education in primary schools, the instructional leadership is low the high impact on the teacher work indiscipline, and result the low work motivation of teachers to produce a high-quality education, which led to poor academic achievement in primary school in Jakarta.It can be said that the increase in the school's academic achievement is influenced by instructional leadership of headmaster, the work discipline and the work motivation high.
The purpose of this study to determine the relationship of the instructional leadership of headmaster and work discipline in enhancing work motivation on academic achievement of students at elementary school in Jakarta.The objectives to be achieved in study was to determine the relationship of the instructional leadership of headmaster and the work discipline and the work motivation of teachers affect students' academic achievement in school, identifying relationships instructional leadership of headmaster and work discipline to the work motivate of teachers and academic achievement.

Design Research
The design of this study will be carried out with quantitative research methods, quantitative research study using descriptive and inferential methods, descriptive methods are used to get a clear picture of mean, median, mode, and standard deviation, statistical inference used correlation analysis with simple regression techniques and regression to answer research questions.

Discussion
From the result of research the instructional leadership of headmaster and the work discipline have a significant relationship to the work motivation and academic achievement.Instructional leadership of Headmaster is very important in school, it is allocated to the achievement are high academic achievement in school, for the headmasters carry out instructional leadership through supervision of teachers and staff in schools, supervision are carried out to improve the quality of teaching, Soetjipto and Kosasih (1999) says supervision headmaster is of all the work done by the a headmaster as supervisor to provide help for teachers to improve teaching.Sagala (2000) says that: "The low level of the profession, achievement, quality of teaching and student learning outcomes, also due to the supervisory role of the school in Indonesia is becoming weaker, less efficient and effective for its intended."The successful implementation of supervision by the principal of the school is working on improving the ability of teachers and staff to jointly develop a conducive teaching and learning situation (Arikunto, 1988).
A study conducted by Edmonds (1979), Brookover et al. (1979), Sapore (1983), Rutter et al. (1979) says that effective schools have headmaster who are able to understand the role played in the instructional program at the school.school are achievement has the instructional leadership of headmaster is achievers anyway, the Gray (1990) states that there is no evidence to suggest that effective schools led by weak leadership.The instructional leadership of headmaster is very important because this patterned leadership can produce effective teaching and learning among teachers and students who can produce a brilliant academic achievement (Hallinger & Murphy, 1985).
The Work discipline of teachers to be one predictor of the academic achievement, academic performance will not be achieved if there is no work discipline of teachers in schools, teachers are not disciplined in carrying out its can duties and responsibilities to inhibit and reduce the academic achievement of students in schools, adherence to regulations set, show discipline teacher in high school, academic achievement can be achieved with the teaching process carried out with discipline, timely teacher in the process of teaching, motivate students to become disciplined in following the teaching process, so that the achievement of the teaching process, without any setbacks and vacancy of teaching hours in schools, indicate compliance and strict adherence to the rules, makes discipline in work related to academic achievement in school.
Davis (2005) states work discipline to strengthen the implementation of management guidelines are considered to be closely related to the achievement.Dahyana (2001) says that conditions of work discipline is not directly created just like that, but must have the will and efforts of all parties, especially the leadership to foster discipline.Nitisemito (1986) states work discipline is a problem that needs to be considered, because of the presence of discipline can be influenced to the effectiveness and efficiency of achievement of organizational goals.Mental discipline must be possessed by every teacher, teacher's success in carrying out his duties will be determined by the level of discipline teachers.Teachers demonstrated good discipline in carrying out its duties and responsibilities will facilitate the work of teachers and to changes in the performance of teachers towards a better and reliable.
The Work motivation related to academic achievement, decline in academic achievement can be caused by low motivation of teachers to work, teachers with low motivation visible from the implementation of the process of teaching poor, the laziness, unwilling to maximize the learning process, the more spent time wasted, taught as needed only, not innovative and creative, thus causing the learning process has poor quality, this can affect the academic achievement of students.According to a preliminary study by Sergiovanni (1976) and McGaw et al. (1992) commitment of teachers to work and for the welfare of students is an important aspect of effective schools.Motivation provides a significant boost in performance improvement of a person.With this motivation to encourage teachers to direct all his energy and ability to achieve optimal performance.Motivation has always been associated with the behavior of teachers in the works, including the urge or desire to work harder and get the job done in the best way.According Christantie and Hartanti (1997) says that the motivation to be associated with learning achievement is the goal to be achieved.
The work motivation of teachers can be enhanced by the leadership of headmaster, the instrucsional leadership of headmaster give a lot of attention on the implementation of the teaching process, the supervision and monitoring, and evaluation to make teachers are always in control of a headmaster.Motivation in work formed from the instrucsional leadership of headmaster, work motivation of teachers will arise in teachers when headmaster give great attention to various problems related to the purposes of the teachers in the teaching process, headmaster always helpful, and the fostering in the implementation of the teaching process makes teachers have a high motivation to work, the more attention to the teaching process from headmaster, showed a sense of valued, respected and needed for teachers in the school.Rusyan (2000) show that: school leadership provide motivation to work to increase the productivity of teacher and student learning outcomes.Peter (1994) because of low motivation, and teacher performance that affect the teaching profession is inseparable from the low contribution of headmaster in developing teacher at the school through supervisory activities.Height the instructional leadership from headmaster to teachers in schools provide high motivation, this is due to the leadership of teaching focused on student learning achievement.Influence leadership is not just in form of teaching, but the motivation or the trigger that can inspire teachers and staff, initiative and creativity in order to develop optimally to improve performance (Yuniarsih & Suwatno, 2008).
Work discipline has a relationship with a teacher motivation, self-discipline of teachers in shaping the personality and attitude of feeling responsible for the duties and functions of a teacher, teachers who have high discipline runs the teaching process as much as possible, for the discipline teacher always tries to produce good teaching process, resulting in the teaching process requires high motivation, achievement motivation high work can be done by instilling discipline good working inside the teacher, The discipline is formed of a self-awareness of teachers to achieve the quality of the teaching process at the school.Nitisemito (1988) There are several factors that influence the occurrence of the behavior of labor discipline, namely: the purpose of the service and work ability, exemplary leader, virtue, justice, supervisory, legal restrictions existing, firmness, and relationship guru is working manusia.Motivasi impulse arising from within, consciously or not to carry out his duties as a teacher.Hasibuan (1996) suggests, a person who has motivation, would improve morale, discipline, improve the atmosphere a good working relationship.

Conclusion
The results of quantitative research hypothesis, testing using correlation and regression among the variables studied, the level of instructional leadership of headmaster in a higher category, it shows that the instructional leadership of headmaster in the school is very good, headmaster in running instructional leadership at the school focusing on improving the quality of education, headmaster conduct supervision, curriculum improvement and development of human resources with good schools, conducting lessons in school management, monitoring, and evaluation and assessment of various teaching activities at school.
The level of teacher discipline, work discipline shows that teachers are in the category of good, work discipline reflected in the performance of teachers and teaching activities at the high school, that teachers have a good working discipline, discipline teachers formed of understanding of rules set out in the school, their devotion a high at school, as well as the implementation of the teaching process in the school well.This proves the work discipline in the school has a high quality.
Stage work motivation of teachers, showing motivation of teachers working in schools in the category of good, visible from the achievement of the expectations and goals set at school.Based on a qualitative assessment, the teacher as teachers have a high motivation to work, as teachers of teachers know and understand the duties and responsibilities as a teacher, so always strive to carry out the teaching process as well as possible.
Stage extremely high academic achievement, student academic achievement seen from the various tests and evaluation of teaching values that have been implemented in schools.Qualitatively excellent academic achievement, students get a satisfactory academic achievement, although there are not satisfactory but only a little, it is necessary to re-evaluate and assess any learning process that has been going on.
There is a positive and significant relationship with the instructional leadership of headmaster and academic achievement demonstrated by the correlation coefficient and coefficient of determination of the relationship between the instructional leadership of headmaster on academic achievement.The relationship between two variables by regression analysis, significant and linear pattern of model equation.This equation gives the information that in the event of an improvement in the instructional leadership of headmaster will be followed by improvement in academic achievement.So the higher instructional leadership of headmaster the higher academic achievement.Conversely, if there is a decrease in the instructional leadership of headmaster, the lower academic achievement.
