Jurusan Pendidikan Jasmani dan Kesehatan, Fakultas Ilmu Keolahragaan, Universitas Negeri Malang. Pembimbing: (I) Prof. Dr. M.E. Winarno, M.Pd, (II) dr. Agung Kurniawan, M.Kes. Kata Kunci: latihan, hurdle hops, jump to box, daya ledak. Kurangnya kemampuan meloncat menyebabkan keterampilan peserta kegiatan ekstrakurikuler dalam bermain bolavoli menjadi kurang baik. Perlu adanya variasi latihan untuk meningkatkan daya ledak otot tungkai diantaranya dengan memberikan program latihan berupa latihan pliometrik hurdle hops dan jump to box. Tujuan dari penelitian ini adalah untuk mengetahui dan mengkaji perbedaan pengaruh latihan pliometrik hurdle hops dan jump to box terhadap daya ledak otot tungkai pada peserta kegiatan ekstrakurikuler bolavoli SMK PGRI 2 Malang. Metode penelitian yang digunakan dalam penelitian ini berupa penelitian eksperimen dengan rancangan kelompok pembanding prates-pascates berpasangan. Subjek coba dalam penelitian ini adalah 20 peserta kegiatan ekstrakurikuler di SMK PGRI 2 Malang. Berdasarkan hasil uji hipotesis data skor prestasi tes akhir latihan hurdle hops dengan latihan jump to box dalam peningkatan daya ledak otot tungkai diperoleh Fhitung 38,41 > dari Ftabel 4,41 dengan taraf signifikansi α = 0.05. Hal ini dapat dibuktikan dengan adanya perbedaan peningkatan rata-rata yang diperoleh oleh masing-masing kelompok latihan. Kelompok latihan hurdle hops hanya mengalami peningkatan rata-rata yaitu sebesar 0,33 sedangkan kelompok latihan jump to box mengalami peningkatan rata-rata sebesar 1,20, sehingga latihan jump to box memberikan pengaruh yang lebih signifikan daripada latihan hurdle hops yang dilakukan selama 16 kali pertemuan. Dari hasil pengujian hipotesis dan pembahasan dalam penelitian yang dilakukan, dapat disimpulkan bahwa: 1) latihan hurdle hops tidak berpengaruh signifikan terhadap daya ledak otot tungkai peserta ekstrakurikuler bolavoli di SMK PGRI 2 Kota Malang, 2) latihan jump to box berpengaruh signifikan terhadap daya ledak otot tungkai peserta ekstrakurikuler bolavoli di SMK PGRI 2 Kota Malang, 3) terdapat perbedaan pengaruh antara latihan jump to box dengan latihan hurdle hops. Latihan jump to box berpengaruh lebih baik terhadap daya ledak otot tungkai peserta ekstrakurikuler bolavoli di SMK PGRI 2 Kota Malang daripada latihan hurdle hops. ABSTRACT Kurniawan. 2017 “Differences Effect of Pliometric Exercise Hurdle Hops And Jump To Box Against Explosive Muscle Limb In Participants of Extracurricular Volleyball Activities at PGRI 2 Malang Vocational High School". Skripsi. Health and Physical Education, Sport Science Faculty, Malang State University. Advisor: (I) Prof. Dr. M.E. Winarno, M.Pd, (II) dr. Agung Kurniawan, M.Kes. Keywords: training, hurdle hops, jump to box, muscle explosion Lack of ability to jump causes the participants extracurricular activities in playing volley ball become less good. There needs to be a variety of exercises to increase the muscle limb power, among others by providing an exercise program in the form of a hurdle hops pliometric and jump to box. The purpose of this research is to know and study the difference of influence between hurdle hops and jump to box plyometric exercise for limb muscle explosive power of volleyball extracurricular participants at PGRI 2 Malang Vocational High School. The method used in this research is experimental research with comparison design of pretest group and posttest group. Subjects in this study were 20 extracurricular participants at PGRI 2 Malang Vocational High School. Based on the results of hypothesis test of achievement score of the final test of hurdle hops and jump to box exercise in increasing limb muscle explosive power obtained that Fcount 38,41> from Ftable 4,41 with significance level α = 0.05. This can be evidenced by the difference in the increasing average gained by each training group. The hurdle hops training group experienced only an increasing average of 0.33, while the jump to box group experienced an increasing average of 1.20, so the jump to box exercise had a more significant effect than the hurdle hops exercise performed 16 times meeting. From the results of hypothesis test and discussion in this research, it can be concluded that: 1) hurdle hops exercise had no significant effect on limb muscle explosive of volleyball extracurricular participants at PGRI 2 Malang Vocational High School, 2) jump to box exercise significantly influence limbs muscle explosive power of volleyball extracurricular participants at PGRI 2 Malang Vocational High School, 3) there is a difference of influence between jump to box exercises with hurdle hops training. The jump to box exercise had a better effect on the limb muscle explosive power of volleyball extracurricular participants at PGRI 2 Malang Vocational High School than the hurdle hops training
