A. Introduction
Many progresses have been made by the Indonesian people from a series of developments that have been carried out continuously during PJP phase I to date, both in the economic sector, education, and other sectors. The progress of the various existing sectors is intended as an effort to realize the ideals of the implementation of development, namely realizing a just and prosperous society as mandated in the 1945 Constitution.
One of the efforts to realize the ideals of national development as stated in the 1945 Constitution is to place the education sector in a very strategic position and role in accelerating development. This role in principle leads to the existence of a goal, namely increasing the prosperity of society as a whole as well as a step to realize important human investment in this era of globalization. Furthermore, specifically the development targets in the field of education for all types and levels of schools as stated in the Law on the National Education System (UUSPN) Number 20 of 2003 are intended as an effort to educate the nation's life and improve the quality of Indonesian people in realizing a just and prosperous society. and enable its citizens to develop themselves, both in terms of physical and spiritual aspects. Educational success can be influenced by many components. The components that affect the success of education are: (1) the teacher component, (2) the student component, (3) the management component and (4) the financing component. These four factors are interrelated and greatly determine the progress of an education.
The function of the school is to develop capabilities and shape the character and civilization of a dignified nation in the context of educating the nation's life, aiming to develop the potential of students to become human beings who believe and fear God, have noble character, are healthy, knowledgeable, capable, creative, independent, and become citizens. A democratic and responsible country.
In schools, the principal is both the father and mother of all the teachers who work in the school. This gives a logical consequence that a school principal must have a higher level of ability so that he can contribute to all the needs of teachers who are psychological and sometimes even physical. 1 Principals including leaders formal in educational institutions. Defined as the head, because the principal is the highest official in the school, the principal as an educational leader seen from the status and method of appointment is classified as an official "Formal Leader or Operational Leader" depending on his achievements and abilities in playing the role of educational leader in the school that has been submitted. responsibility to him. 2 Based on the above opinion, the responsibility of the principal as an educational leader is to create effective school management which can be seen in the size of the realization of a good teaching and learning situation, so that teachers can teach and students can learn well so as to produce quality graduates. Quality _____________ development and existence of the organization. 8 In the organizational context according to Suryadi, the most urgent is effective leadership and followed by an action plan, and leadership is also a determining factor in the success or failure of an organization and business. 9 The success of the organization is the success of a leader. Leadership in the organization is the spirit to turn the wheels of empowering the organization. That is, the central role in the organization can not be separated from the performance of a leader to move the potentials that exist in the organization. A leader is successful in his leadership if they understand the existence of their organization as a complex and unique organization, and are able to carry out the roles that are given the responsibility to lead. One of the roles of a leader intended in this case is to influence and mobilize others to work towards achieving the organization's vision and mission without coercion. Of course, this is not something that every leader or leader can easily do, such as turning the palm of the hand, but something that is difficult. Difficult does not mean it can't be done, but it takes a process.
To improve the effectiveness of management in schools, principals are expected to have strategies in communicating. Communication strategy as a method, technique or way of communication works so that we can achieve the goals that have been set. Communication strategies are always associated with the following: 1). Who am I talking to; 2). What do I mean by speaking; 3). What message to convey to someone; 4). The way in which I convey a message to someone; and 5). How to measure the impact of the message.
Mastery of communication strategies is a basic and vital ability that a school principal must have in order to support the achievement of school goals. Through the implementation of an effective communication strategy, it is hoped that a school principal will be able to organize and coordinate the willingness of school members to jointly achieve school goals with a pleasant atmosphere (enjoyable), and high activity both mentally, physically, socially, and emotionally. It is through the application of this effective communication strategy that a principal is also a school principal.

B. Research Methodology
The subject of this research is directed at finding data from supervisors, principals, employees, teachers and students. The search for data started from the supervisor element as a key informant using snow-ball sampling (snowball), then the next informant was the principal, staff, teachers and students. Data achievement will be stopped when no more data variations appear or surface or experience saturation (naturation). So the number of informants in this research is not determined with certainty depending on the level of data needed. This research was carried out using a _____________ knowing and understanding the characteristics of the recipient (audience), means an opportunity to achieve successful communication.
Influence Influence or effect is the difference between what the recipient thinks, feels and does before and after the recipient of the message. Therefore, influence can also be interpreted as a change or strengthening of beliefs in one's knowledge, attitudes and actions as a result of the recipient of the message.

Feedback
Some think that feedback is actually a form of influence that comes from the recipient. However, feedback can actually come from other elements such as messages and media, even though the message has not yet reached the recipient. For example, a draft letter that requires changes before it is sent, or the tool used to convey a message is experiencing problems before it reaches its destination. Things like this become the feedback received by the source.
Environment Environment or situation are certain factors that can affect the course of communication. These factors can be classified into four types, namely the physical environment, the socio-cultural environment, the psychological environment and the time dimension.
The physical environment shows that a communication process can only be reviewed if there are no physical barriers, such as geographic. Communication is often difficult to do because the distance is so far, where it is not available where there are no communication facilities such as telephones, post offices or roads. The social environment shows socio-cultural, economic and political factors that can hinder communication, for example, the similarity of language, beliefs and customs and social status.
The psychological dimension is a psychological consideration used in communication, for example to avoid criticism that offends other people. Presenting material that is appropriate for the age of the audience. This psychological dimension can be called the internal dimension. 25 While the time dimension shows the right situation to communicate. Many communication processes are delayed due to time considerations, such as seasons. However, it should be noted that because of the time dimension, information have value. Each element has a very important role in building the communication process. Even the objectives of these elements are interdependent on each other. This means that without the participation of one element will have an influence on the course of communication. Changara (2004:63) suggests that: if communication is seen from a broader meaning, it is not only interpreted as the exchange of news and messages but as individual and group activities regarding the exchange of data, facts and ideas, then its function in every social system is as follows: 26 1) Information, collection, storage, processing, dissemination of news, facts, messages, opinions and comments needed to be understood and act clearly on environmental conditions or other people in order to make the right decisions. 2) Socialization (correctional) is the provision of knowledge resources that enable individuals to behave and act as effective members of society so that they are aware of their social functions which in the end they can be active in society. 3) Motivation, namely explaining the short-term and long-term goals of each community, encouraging people to make choices and desires, encouraging individual and group activities based on shared goals to be achieved. 4) Debate and discussion, providing and exchanging the necessary facts to allow agreement or resolving differences of opinion on public issues, providing relevant evidence needed for the public interest so that the public is more involved in matters of common interest at the national and international levels local. 5) Education, transfer of knowledge so as to encourage intellectual development, formation of character and skills and skills needed in all areas of life. 6) Promoting culture, dissemination of cultural and artistic products with the aim of preserving the heritage of the past, developing culture by broadens one's horizons, builds imagination and encourages creativity and aesthetic needs. 7) Entertainment, dissemination of signals, symbols, sounds and images of drama, dance; arts, literature, music, sports, games and others for recreation, group and individual enjoyment. 8) Integration, providing nations, groups and individuals with the opportunity to get the messages they need so that they can know each other and understand and appreciate the conditions, views and desires of others.
