Abstract

Penelitian ini bertujuan untuk meningkatkan kemampuan lompat jauh pada siswa SMA di Banda Aceh. Peneliti menemukan bahwa kemampuan lompat jauh siswa masih kurang memuaskan karena sarana dan prasarna yang tidak optimal dan kurang percaya diri siswa yang disebabkan program pelatihan yang belum optimal. Jenis penelitian adalah penelitian eksperimen dengan pendekatan kuantitatif. Populasi penelitian ini seluruh siswa kelas XI yang berjumlah 80 orang dan yang terpilih menjadi sampel berjumlah 10 orang. Berdasarkan hasil analisis data, rata-rata hasil lompat jauh sebelum intervensi latihan (pretest) adalah 3,38 meter, Sedangkan setelah perlakuan pelatihan (Posttest) meningkat menjadi 4,19 meter. Selanjutnya, uji normalitas dan homogenitas agar syarat analisis statistik terpenuhi secara valid Hasil uji normalitas menggunakan Liliefors menunjukan nilai L_hitung 0,17848 (pretest) dan 0,13869 (posttest), keduanya lebih kecil dibandingkan L_tabel 0,258. Hal ini berarti data berdistribusi normal pada kedua tahap pengukuran. Uji homogenitas varians juga menunjukan F_hitung 1,376214 lebih kecil dari F_tabel 1,83311, yang menyatakan varians kedua data homogen dan layak dibandingkan. Selanjutnya, didapatkan nilai thitung 2,8615 lebih besar dari ttabel 1,8331, yang membuktikan bahwa terdapat peningkatan yang signifikan pada kemampuan lompat jauh siswa setelah mengikuti latihan plyometrics high hurdle jump with short ground contac. Dengan kata lain, latihan tersebut memberikan pengaruh positif yang nyata terhadap peningkatan jarak lompatan jauh siswa.
