PENGARUH HANDGRIP STRENGTH, FLEKSIBILITAS PERGELANGAN TANGAN DAN KOORDINASI MATA TANGAN TERHADAP KETERAMPILAN FOREHAND DRIVE (Studi Kausalitas Pada Siswa Peserta Ektrakurikuler Bulutangkis SMAN Se-Kota Bekasi)

Tujuan dari penelitian mengetahui seberapa besar pengaruh handgrip strength, fleksibilitas pergelangan tangan dan koordinasi mata tangan terhadap keterampilan forehand drive pada siswa peserta ektrakurikuler bulutangkis SMAN Se-Kota Bekasi. Metode penelitian yang digunakan adalah metode kuantitatif, dengan teknik test dan pengukuran. Data dianalisis dengan analisis jalur. Populasi ditetapkan pada siswa yang mengikuti ekstrakurikuler bulutangkis SMAN Se-Kota Bekasi sebanyak 60 siswa. Teknik pengambilan sampel yang digunakan total sampling, sehingga sampel berjumlah 60 orang. Instrument handgrip strength, fleksibilitas pergelangan tangan, koordinasi mata tangan, dan forehand drive skill pada cabang olahraga bulutangkis. Instrument disusun oleh peneliti dan dikonsultasikan dengan pakar Tes dan Pengukuran Olahraga. Hasil penelitian dihitung melalui SPSS versi. 21 menunjukkan bahwa: Pengaruh langsung yang diberikan variabel Handgrip Strength (X1) terhadap variabel Koordinasi Mata Tangan (X3) yaitu sebesar 0,107. Kemudian pengaruh langsung yang diberikan variabel Fleksibilitas Pergelangan Tangan (X2) terhadap variabel Koordinasi Mata Tangan (X3) yaitu sebesar 0,038. Kemudian pengaruh langsung yang diberikan variabel Handgrip Strength (X1) terhadap variabel Forehand Drive (Y) yaitu sebesar 0,071. Kemudian pengaruh langsung yang diberikan variabel Fleksibilitas Pergelangan Tangan (X2) terhadap variabel Forehand Drive (Y) yaitu sebesar -0,047. Dan terakhir pengaruh langsung yang diberikan variabel Koordinasi Mata Tangan (X3) terhadap variabel Forehand Drive (Y) yaitu sebesar 0,358. Hasil dari perhitungan uji Sobel (Sobel Test) diperoleh bahwa nilai probabilitas satu arah (One-tailed probability) sebesar 0,0188410 < 0,05. Sehingga dapat disimpulkan bahwa variabel Handgrip Strength (X1) berpengaruh secara tidak langsung melalui Koordinasi Mata Tangan (X3) terhadap Forehand Drive (Y). Hasil dari perhitungan uji Sobel (Sobel Test) diperoleh bahwa nilai probabilitas satu arah (One-tailed probability) sebesar 0,035 < 0,05. Sehingga dapat disimpulkan bahwa variabel Fleksibilitas Pergelangan Tangan (X2) berpengaruh secara tidak langsung melalui Koordinasi Mata Tangan (X3) terhadap Forehand Drive (Y). Kata kunci: Handgrip Strength; Fleksibilitas Pergelangan Tangan; koordinasi Mata Tangan Keterampilan Forehand Drive***The purpose of the study was to determine how much influence handgrip strength, wrist flexibility and eye-hand coordination had on forehand drive skills in badminton extracurricular participants at SMAN Bekasi City. The research method used is a quantitative method, with test and measurement techniques. Data were analyzed by path analysis. The population is determined to be 60 students who take badminton extracurricular at SMAN Bekasi City. The sampling technique used is total sampling, so the sample is 60 people. Instrument handgrip strength, wrist flexibility, hand eye coordination, and forehand drive skills in badminton. The instrument was prepared by the researcher and consulted with experts in Sports Tests and Measurements. The results of the study were calculated through the SPSS version. 21 shows that: The direct effect given by the Handgrip Strength variable (X1) on the Eye-Hand Coordination variable (X3) is 0.107. Then the direct effect given by the Wrist Flexibility (X2) variable on the Eye-Hand Coordination variable (X3) is 0.038. Then the direct effect given by the Handgrip Strength (X1) variable on the Forehand Drive (Y) variable is 0.071. Then the direct effect given by the Wrist Flexibility (X2) variable on the Forehand Drive (Y) variable is -0.047. And lastly, the direct effect given by the Eye-Hand Coordination variable (X3) on the Forehand Drive (Y) variable is 0.358. The results of the calculation of the Sobel test (Sobel Test) obtained that the one-tailed probability value is 0.0188410 <0.05. So it can be concluded that the Handgrip Strength (X1) variable has an indirect effect through Eye-Hand Coordination (X3) on the Forehand Drive (Y). The results of the calculation of the Sobel test (Sobel Test) obtained that the one-tailed probability value is 0.035 < 0.05. So it can be concluded that the Wrist Flexibility variable (X2) has an indirect effect through Eye-Hand Coordination (X3) on the Forehand Drive (Y).
