The sampling technique used is simple random technique. The population in this study -were students of State Vocational School 40 Jakarta. With a population of students in grade XI is affordable Marketing and XI as many as 72 students. Then based on a sample of the Issac and Michael table, retrieved a sample of 58 students -with a sampling error off 5%. To capture data from variable X is used questionnaire Likert scale models for the Self-concept. Before the instrument is used, tested the validity first. For variable X, from 30 points after a validated this claim, there are 7 items that drop revelation, -while meeting the criteria or valid revelation consists of 23 items. Calculation of the X variable reliability using Cronbach alpha formula. The results of the X variable reliability of 0,922 which means the level of reliability of the instrument will show a high rate, while the data Y (Learning Achievement) from the average value of the first semester report cards in XI marketing classes and X Administration. The resulting regression equation is Y = 21,19 + 0.608 X. Test requirements analysis of the normality test error of estimated regression of Y on X with the test result liliefors Lcount = 0,055, while Liable for n = 58 at 0.05 significant level is 0.116, for Lhitung Ftable, ie 25,94 > 4,02, meaning that ihe regression equation is significant. Correlation coefficient of Pearson Product Moment generating rxy = 0,620 keberartian correlation test is then performed using the t-test and the resulting tcount = 5,91 and Ttable – 1,68 at significant level and dk = 56. It can be concluded that the correlation coefficient rxy = 0,563 is significant. The coefficient of determination obtained for 38,43%, which indicates that 38,43% Performance is determined by the Self-concept study. The results of this study indicate there is a positive The Correlation Between Self Concept With Learning Achievement Of Student At State Vocational School 40 Jakarta
