Abstract

Masalah dalam penelitian ini adalah kurangnya aktivitas bermain anak saat sekarang ini sehingga membuat anak-anak menjadi malas melakukan aktivitas bermain dan tidak ingin bergerak. Tujuan dari penelitian ini adalah melihhat sejauh mana hubungan aktivitas bermain dan status izi terhadap kemampuan motorik anak. Penelitian ini metode penelitian dalam penelitian ini adalah kolerelasi ganda. Untuk mengukur atau instrumen dalam penelitian ini peneliti menggunakan angket, test antropometri serta melakukan test kemampuan motorik yang akan diterapkan pada siswa SD N 200309 desa Purwodadi Kota Padangsidempuan yang berjumlah 25 siswa. Pengambilan sample dalam penelitian ini menggunakan teknik purposive sampling. Hasil penelitian dari penelitian ini yang di dapat dari hasil uji Validitas dan Reabilitasnya menggunakan taraf signifikan α = 0.05. aktivitas bermain dengan kemampuan motorik, dengan nilai thitung = 4,688 > ttabel = 1,711, antara status gizi dengan kemampuan, dengan nilai thitung = 2,287 > ttabel = 1,710, antara aktivitas bermain dan status gizi secara bersama-sama dengan kemampuan motorik siswa SD Negeri 200309 Desa Purwodadi Kota Padangsidimpuan, dengan nilai Fhitung = 9,94 > Ftabel = 3,44

Abstract

The research addresses the low proficiency in executing jump floating serves among volleyball players, influenced by factors such as arm muscle explosive power, leg muscle explosive power, hand-eye coordination, and concentration. The study aimed to evaluate the impact of these factors on players' jump floating serve abilities. Using a quantitative approach and survey method, data were collected from 24 male volleyball players at Padang State University. The instruments included the jump floating serve test, One Hand Medicine Ball Put for arm muscle explosive power, Vertical Jump Test for leg muscle explosive power, ball throw response for hand-eye coordination, and Grid Concentration Test for concentration. Path analysis was utilized for data analysis. The results revealed: (1) a significant direct impact of arm muscle explosive power on jump floating serve ability (Py1= 0.358), (2) no significant direct impact of leg muscle explosive power on jump floating serve ability (Py2= 0.119), (3) a significant direct impact of hand-eye coordination on jump floating serve ability (Py3= 0.343), and (4) a significant direct impact of concentration on jump floating serve ability (Py4= 0.251). Additionally, there were no direct effects of arm muscle explosive power, leg muscle explosive power, or hand-eye coordination on concentration (P41= 0.043, P42= 0.242, P43= 0.427). However, indirect effects on jump floating serve ability through concentration were found for arm muscle explosive power (ꜫ1 = 0.090), leg muscle explosive power (ꜫ2 = 0.029), and hand-eye coordination (ꜫ3 = 0.107).
