Abstract

The problem in this research is still a lot of students at the time of passing down not maximized it can researchers see when girls do passing under the ball was not until stricken opponent, then the ball is often on the net so that teams do not get points it is because the muscle strength of the arm and shoulder still weak , Further resistance is still low student chapters in training students easily tired. The next problem is the ball often deviated when a student passes this result to a friend and hand-eye coordination students is still low. Also pass the error caused by the level of accuracy the student is still weak. Student body balance is still low this occurs when a student suddenly received the ball on the opponent's students are not ready so the position of the body is not well controlled. This study aims to determine the contribution of muscle strength of the arm and shoulder with passing ability under volleyball in grade VII SMP 22 Pekanbaru. This type of research is correlational where correlation is a statistical tool, which can be used to compare the results of measurements of two different variables in order to determine the level of association between these variables. Population in this research is student-grader VIIa SMP 22 Pekanbaru many as 11 students, Given a population of only a little, the researchers took samples of the total sampling techniques or all the population sampled, thus the sample amounted to 11 samples daughter. Data collection techniques in this study through a test measuring the strength of the arm and shoulder muscles to the test measurement phus up. To determine the ability of passing under volleyball passing the test used under volleyball. The analysis used is product moment correlation to see the connection or the variables X and Y significant. To see the size of the contribution using the formula KD = r 2 x 100%. Based on the analysis of data obtained by the correlation coefficient of r = 0.633 where or significance was tested by t test and obtained t count equal to 2.450 means thitung> t table (1,833) thus variable X with Y relationship significantly with the coefficient of determination (KD) of 40.02%.
