Abstract

Abstract: The problem of this research is base on observation which was found by the researcher while do test of long jump male students in SMK Farmasi Ikasari Pekanbaru. Students did not anexpected result (3.60m). This it because is explosive power of leg muscle students grade X of SMK Farmasi Iksari Pekanbaru not good enough. Sampling used in this research is total sampling. Sample of this research is in the amount of 26 students. The instrument used in this research are standing broad jump to test the explosive power of the leg muscle and long jump to test the long jump itself. Data were analyzed statistically to test the normality with liliefors test on the significant level of =0,05. Value of variable X withL0maks = 0,0905 < Ltabel = 0,173 and variable of Y L0maks = 0,0848 < Ltabel = 0,173, in conclusion value of data X and Y are normal distribution. Based on the analysis data, it is obtained that the correlation of X and Y is rcount = 0,662 from rtable = 0,396. The correlation of variable to another variable is determined by rcount> rtable. There is a significant correlation between the explosive power of the leg muscle to the long jump results of X grade male students of SMK Farmasi Ikasari Pekanbaru.Keywords: Explosive Power Of Leg Muscle, Long Jump.

Abstract

This study examines the low learning outcomes of students at SD Negeri 004 Tanjungpinang Barat, which are allegedly influenced by nutritional status, concentration, and self-control skills. This quantitative study uses a correlational design with an ex-post-facto method. The research sample was 100 students selected through purposive sampling technique. Nutritional status data were obtained from height and weight measurements, concentration was measured by the grid concentration test, self-control skills by the TGMD-2 subtest, and learning outcomes were obtained from school data. The data were analyzed using path analysis. The results showed that there was a direct relationship between nutritional status, concentration, and self-control skills on student learning outcomes. The contribution of nutritional status to learning outcomes was 16.66%, concentration was 21.48%, and self-control skills were 19.75%. In addition, there is an indirect relationship between nutritional status and concentration on learning outcomes through self-control skills. Overall, nutritional status, concentration, and self-control skills contribute significantly to student learning outcomes by 35.04%.
