Leg Muscle Power

This study aims to determine the correlation between leg length and leg muscle power on the results of long passing in soccer games. The population in this study were all Wakanda football players FC Deliserdang in 2020. A total sample of 20 was obtained by total sampling technique. The instruments used in this study were an instrument for measuring leg length, a standing broad jump instrument for leg muscle power and a long passing instrument was the gastric passing test from Bobby Charlton. The results of the first statistical analysis show that the correlation coefficient is 0.501, which is a strong enough correlation. The R square of 0.251 explains that the length of the legs has an effect of 25.1% on the results of long passing football, while 74.9% is influenced by other variables. Based on the results of the t-test, it is known that tcount> ttable where (2.45> 1.729), so it can be concluded that there is a significant relationship between leg length and long passing results in Wakanda football player FC Deli Serdang in 2020. The result of the second statistical analysis shows a correlation coefficient of 0.457, which is a strong enough correlation. The R square of 0.209 explains that leg muscle power has an effect of 20.9% on the results of long passing football while 79.1% is influenced by other variables. Based on the results of the t-test, it is known that tcount> ttable where (2.183> 1.729), so it can be concluded that there is a significant relationship of leg muscle power to the long passing results of the Wakanda FC Deli Serdang football player in 2020. The result of the third statistical analysis shows that the correlation coefficient is 0.506 which is a strong enough correlation. The R square of 0.256 explains that leg length and leg muscle power have an effect of 25.6% on the results of soccer long passing while 74.4% are influenced by other variables. Based on the results of the t-test, it is known that tcount <ttable where (0.344 <1.729), so it can be concluded that there is no significant correlation between leg length and leg muscle power together on the long passing results of football players Wakanda FC Deli Serdang in 2020.

This study aims to find out and test empirical data related to the relationship between organizational culture, discipline and teacher teaching productivity simultaneously or separately. In this study, the authors used a survey method with a correlational and regression approach to quantitative data obtained from the object of research, namely Private Primary School teachers in Matraman sub-district. The sample of this study was 93 respondents out of a total of 120 private elementary school teacher populations in Matraman District in the odd semester of the 2018/2019 academic year. Data collection is done by using questionnaire / questionnaire, observation, and documentation techniques. The type of analysis used is correlation analysis and descriptive described regression. The results of this study are: First, there is a positive, strong and significant relationship between organizational culture and teacher teaching productivity with a correlation coefficient (r) of 0.751 and a coefficient of determination (R2) of 56.4%. The direction of influence is indicated by the regression equation Ŷ = 31,073 + 0.749 X1, it can be read that each increase in one unit score of organizational culture (X1) affects the increase in teacher teaching productivity score (Y) of 0.749 points. Second, there is a positive, strong and significant relationship between discipline and teacher teaching productivity with a correlation coefficient (r) of 0.736 and a coefficient of determination (R2) of 54.2%. The direction of influence is indicated by the regression equation Ŷ = 31,073 + 0,749 X2, it can be read that each increase in one unit of discipline score (X2) affects the increase in the teacher's teaching productivity score (Y) by 0.749 points. Third, there is a positive, strong and significant relationship between organizational culture and simultaneous discipline with teacher teaching productivity. The correlation coefficient (r) is 0.815 and the coefficient of determination (R2) is 66.4%. The direction of influence is indicated by the regression equation Ŷ = 12,191 + 0,467 X1 + 0,427 X2. From this equation it can be read that each increase in one independent unit score of organizational culture and discipline jointly affects the increase in teaching productivity scores 0.894.
