Abstract

Abstrak ___________________________________________________________________ Tujuan penelitian ini adalah untuk mengetahui sumbangan kekuatan otot tungkai, kelentukan pergelangan kaki, dan kecepatan ayun tungkai terhadap tendangan jarak jauh. Metode penelitian yang digunakan adalah survei. Populasi Penelitian ini adalah seluruh anggota klub Persitaku tahun 2014 yang berjumlah 24 orang. Teknik pengambilan sampel dalam penelitian ini menggunakan teknik sampel jenuh. Analisis  data menggunakan statistik deskriptif dan uji hipotesis dengan uji regresi sederhana dan ganda meliputi: uji normalitas data dengan kolmogrov-smirnov, uji homogenitas dengan chi-square, uji lineritas dengan garis regresi dengan nilai F, uji keberartian model garis regrasi. Diolah dengan SPSS 20. Hasil analisis menunjukkan Ada sumbangan yang signifikan antara kekuatan otot tungkai terhadap hasil tendangan jauh sebesar 0,494 atau 49,4%, adanya sumbangan yang signifikan antara kelentukan pergelangan kaki terhadap hasil tendangan jauh sebesar 0,450 atau 45%, tidak ada sumbangan yang signifikan antara kecepatan ayun tungkai terhadap hasil menendang jauh yaitu sebesar 0,026 atau 2,6%, dan terdapat sumbangan yang signifikan antara kekuatan otot tungkai, kelentukan pergelangan kaki tungkai, kecepatan ayun tungkai terhadap hasil tendangan jauh pada Klub Sepakbola Persitaku Tangkil Kulon Kabupaten Pekalongan Tahun 2014 sebesar 0,735 atau 73,5%.   Abstract ___________________________________________________________________ The purpose of this study is to find out the influence of  limbs muscle strength , ankle flexibility , and speed of the swing leg kick to long shoot. The method use survey test . This study population is the entire club members Persitaku 2014 , amounting to 24 people . Samples were taken 24 club soccer player Persitaku 2014.

Abstract

The problem of low ability to understand science concepts in elementary school students is the basis of this study. The study aims to determine the effect of the Problem Based Learning model assisted by Educaplay media on the ability to understand science concepts in elementary school students. The study used a quasi-experimental method with a Nonequivalent Control Group Design. The research sample consisted of 60 students selected using purposive sampling, consisting of 30 students in the experimental class and 30 students in the control class. Data were collected through a concept understanding test and analyzed using descriptive statistics, t-test, effect size, and N-gain. The results showed that the ability to understand science concepts in the experimental class increased significantly compared to the control class. The effect size value of 0.889 indicates a high influence, while the N-gain results showed that the increase in the experimental class was in the high category and the control class in the medium category. These findings indicate that the Problem Based Learning model assisted by Educaplay media is effective in improving the ability to understand science concepts and can be an alternative for innovative learning in elementary schools.
