INTRODUCTION
At present the reality in Indonesia is that the quality of education of students is low. Lately often seen many events that show that to find the identity of adolescents or their identities adolescents commit negative behavior. Sometimes these negative behaviors they can from the often they access social media without filtering out any information they receive. Negative behaviors that are generally considered common among adolescents include irresponsibility, disrespect for teachers, undisciplined, not independent, lazy to learn and behave rudely towards peers, because some in academic matters that result in poor mastery of children on subject matter and achievement in school [1]. As these behaviors develop, many of these students make it the wrong culture among students. one of which is caused by the incessant flow of globalization International Journal of Educational Dynamics  Desember 2019 p_ISSN 2655-4852 e_ISSN  and global science and technology that hit Indonesia, especially in urban areas. The many cases of student involvement in brawls, school drug use and other forms of juvenile delinquency are far from the description of educated students who are virtuous and responsible. Based on the increasingly apprehensive adolescent problems, it shows that in Indonesia the character possessed by teenagers is still low. Research conducted by [2] found that boys have weaker characters than girls. Previous studies found that boys are more susceptible to having negative behaviors compared to girls. The problem of the low character of students becomes very worrying and must be handled wisely and well. Basically there are many factors that are able to influence student learning achievement ranging from the characteristics of the individual itself to the environment both in the family and school. One factor that occurs is the excessive use of social media. Social media is mostly used by students as a means of communication, finding friends in cyberspace and looking for learning material. But not infrequently the communication that is done is something that is not too important and makes it easy for them to have many friends, because social media is connected to the whole world. So being active on social media is more important than repeating lessons and learning which they find boring. The situation resulted in a lot of time wasted and disrupted student activities, such as study schedules, eating, sleeping, socializing with the real world, and so on. So that the teaching and learning process lived in school and even learning at home is reduced, because the amount of time spent using social media so that students are too busy accessing and playing with fun in social media, so that children's learning interest is disrupted which causes learning achievement decreases.
Apart from social media, strong learning achievements will also be influenced by the emergence of self-discipline where that discipline is something regarding one's self control of the forms of rules. A student needs to have a disciplined attitude by doing exercises that strengthen himself to always get used to being obedient and enhance selfcontrol. Discipline that arises from his own awareness will be more stimulating and long-lasting compared to the attitude of discipline that arises because of the supervision of others. High discipline attitude is needed in learning situations, because only in situations of discipline can the teacher's knowledge, experience, and expertise work effectively. The attitude of students who have high learning discipline will always carry out the activity of learning on a regular basis, completing tasks on time, participating in all learning activities at school, diligently reading textbooks. Students who have the attitude of their discipline will have high responsibilities. Relation to the process of learning activities of a child who is accustomed to being disciplined will be able to use the learning time as well as possible, both at home and at school.
Discipline can grow and be fostered through training, education or inculcation of habits that must begin in the family environment, starting in childhood and continue to grow so that it becomes a stronger discipline. As mentioned by Joko Sumarno "that the term discipline is obedience and obedience that arises because of the awareness and encouragement in that person". Without good discipline the atmosphere of a positive school discipline provides calm and orderly support for the learning process. Reducing the intensity of access to social media and increasing discipline of learning play an important role in learning achievement. With behavior that is aware of education, and the discipline of learning that students become diligent in the teaching and learning process and by improving the quality of learning, the quality of student achievement can be realized properly.
Students who in the learning process have a strong attitude and discipline will succeed in their learning.
Learning achievement is one result of a process of teaching and learning activities.
Learning achievement serves as an indicator of student success in a subject. According to [3] "Learning achievement is an indicator and quantity of knowledge which is dominated by students". [4] defining learning achievement is a proof of learning success or the ability of a student to carry out his learning activities in accordance with the weight achieved. Learning achievement is the result obtained by students after going through the learning process to find out what they do not know and is a maximum measure of the level of success achieved by students after conducting the learning process for a period of time determined together in an educational institution. Achievement of student learning achievement can be seen through the implementation of the evaluation of learning outcomes conducted by teachers of students which are proven and demonstrated through the value of the results of tests or examinations taken by students. Good learning achievement is the thing most coveted by students who are learning and said to be achieved if students experience the development and improvement of expected behavior according to learning objectives. Success in learning depends on each individual, students differ from one another in the achievement of learning achievement, but basically the expected results are high learning achievement. Based on interviews, discussions and observations of researchers with the principal and vice principals in the fields of curriculum, student field and several teachers and students of SMKN 5 Padang on March 4 2019, data on the number of students in 2018/2019 class X amounted to 561, and get information that students tend to be bored and uncomfortable with the school environment that is not good and uncomfortable so that the lessons become boring and not conducive to learning so that students are not motivated in learning and not achieving good learning outcomes. Based on the information the researcher obtained through the vice principal in the field of curriculum, the school implemented a remedial program and the aim was to complete the grades of students for the implementation of the learning process that there were still not yet mastered students. And while SMKs are required to be able to produce graduates who are experts in the fields in accordance with their respective departments so that they are ready to enter the world of work and industry. Based on the description of diaatas and identified phenomena, many factors are thought to influence the learning achievement of students of Vocational High School 5 Padang. This research will be more complete in discussing the problem to be examined, if all the factors described in the identification of the problem above can be revealed. However, given the wide scope of the problem and the limitations of the researchers, this study is limited to only two (3) variables which are thought to be very dominant to have an influence on student learning outcomes at Vocational High School 5 Padang, namely: social media variables, learning discipline and learning achievement.
Furthermore, the formulation of the problem is: is there a significant influence of learning discipline on student achievement in class X Vocational High School 5 Padang. The purpose of this study is to Analyze the learning discipline of learning achievement in Vocational High School 5 Padang class X. This research is relevant to the research conducted by [5] with the title "The Effect of School Environment and Learning Motivation on Student Achievement in Class X SMK Pasundan 1 Bandung. The results revealed that Tengku Umar Sumedang Vocational School was included in the good category with a percentage of 58.9 students' learning motivation with a good category with a percentage of 69.25% and a sufficient student learning presentation with a percentage of 7.38%.
Furthermore, this study is also relevant to research conducted by [6] "The Intensity Relationship of Accessing Facebook with Learning Motivation of Tenggarong Seberang High School 2 students." The results of the study concluded that the low intensity of accessing Facebook students was followed by high motivation in learning. And conversely the more often students access Facebook, the lower the motivation to learn they have. Then it is also relevant to his research [7] "The Effect of Internet Use on Student Learning Achievement in Economics Class X in Smhi Budman War II". The results of the study concluded the magnitude of the effect of the use of the internet on student achievement in economic class X in Budhi Warman II High School. The results showed that the coefficient of determination was 64%. So from the above information it can be concluded that the use of the internet affects the economic subjects of class x 64% while 36% is determined by other factors namely learning styles, environment and teachers in mastering internet learning media.

Furthermore, to see the effect of the discipline of learning on student achievement in class X at SMK Negeri 5 Padang, the terms of hypothesis analysis (normality and linearity) are conducted, the hypothesis test and discussion of the results of the study. Normality test is used to determine whether the population data is normally distributed or not [9]. Normality test is done using the Liliefors formula which is calculated manually. The normality test results can be seen in the following table 4: The linearity test aims to find out whether the learning discipline variable (X) has a linear correlation or not significantly to the learning achievement variable (Y).
Linearity test is usually used as a requirement in correlation analysis or linear regression. It can be said that there is a significant linear relationship between variables if the significance is greater than alpha (0.05). The data linearity test results can be seen in the following table 5:   The results of the analysis of this study contain a description of the data on the effect of learning discipline on learning achievement. Based on this research, it is known that the influence of learning discipline (X) on learning achievement (Y) of class X students at Vocational High School 5 Padang is 11.97%. The results of data analysis and hypothesis testing show that the hypotheses tested in this study were accepted.
