Penelitian ini bertujuan untuk mengetahui tentang: (1) pengaruh Squat Jump Cone terhadap kekuatan, Kecepatan dan daya tahan otot tungkai. (2) pengaruh Lateral Jump Cone terhadap kekuatan, Kecepatan dan daya tahan otot tungkai, (3) pengaruh Lateral Trapping Jump Drill terhadap kekuatan, Kecepatan dan daya tahan otot tungkai. (4) pengaruh Trapping Jump Drill terhadap kekuatan, Kecepatan dan daya tahan otot tungkai. Sampel penelitiannya adalah Siswi Sekolah Menegah Atas Kelas 10 sebanyak 40 Siswi dibagi menjadi empat kelompok dengan masing-masing kelompok berjumlah 10 Siswi. Kelompok eksperimen I mendapat perlakuan latihan Squat Jump Cone, Kelompok Eksperimen II mendapat perlakuan latihan Lateral Jump Cone, Kelompok Eksperimen III mendapat perlakuan latihan Lateral Trapping Jump dan Kelompok Eksperimen IV mendapat perlakuan latihan lateral trapping jump. Penelitian ini dilakukan selama 6 minggu. Jenis penelitian ini menggunakan penelitian kuantitatif dengan metode quasi eksperimen. Desain penelitian menggunakan faktorial, serta analisis data menggunakan MANOVA. Proses pengambilan data dilakukan dengan Jump meter digital untuk daya ledak otot tungkai, leg dynamometer untuk kekuatan otot tungkai, serta tes lari 30 m untuk mendapatkan data Kecepatan, pada saat pre-test dan post-test. Kemudian data tersebut dianalisis dengan menggunakan seri SPSS 25. Data kelompok I meliputi: daya ledak otot tungkai meningkat 8.370%, kekuatan meningkat 8,768%, Kecepatan meningkat 1,18%. Kelompok II meliputi: daya ledak otot tungkai meningkat 7,288%, kekuatan meningkat 7,915%, Kecepatan meningkat 0,989%. Kelompok III meliputi: daya ledak otot tungkai meningkat sebesar 6,672%, kekuatan meningkat sebesar 9,794%, Kecepatan meningkat sebesar 0,880%. Kelompok IV meliputi: daya ledak otot tungkai meningkat sebesar 6,476%, kekuatan meningkat sebesar 9,542%, Kecepatan meningkat sebesar 0,928%.  Hasil di atas dapat disimpulkan; (1) Terdapat pengaruh latihan Squat Jump Cone terhadap daya ledak otot tungkai, kekuatan dan Kecepatan (2) Terdapat pengaruh latihan Lateral Trapping Jump Cone terhadap daya ledak otot tungkai, kekuatan dan Kecepatan (3) Terdapat pengaruh latihan Lateral Trapping Jump Drill  terhadap daya ledak otot tungkai, kekuatan dan Kecepatan otot tungkai. (4) Terdapat pengaruh latihan Trapping Jump Drill terhadap kekuatan, Kecepatan daya tahan otot tungkai.

This research aims to find out: (1) the effect of jump Cone squats on leg muscle strength, speed and endurance. (2) the effect of Lateral Jump Cones on leg muscle strength, speed and endurance, (3) the effect of Lateral Trapping Jump Drill s on leg muscle strength, speed and endurance. (4) the effect of Trapping Jump Drill  on strength, speed and endurance of leg muscles. The research sample was 40 Class 10 Upper Middle School students divided into four groups with 10 students in each group. Experimental Group I received Squat Jump Cone training treatment, Experimental Group II received Lateral Jump Cone training treatment, Experimental Group III received Lateral Trapping Jump training treatment and Experimental Group IV received Lateral Trapping Jump training treatment.

This research was conducted for 6 weeks. This type of research uses quantitative research with quasi-experimental methods. The research design uses factorial, and data analysis uses MANOVA. The data collection process was carried out using a digital jump meters for leg muscle explosive power, a leg dynamometer for leg muscle strength, and a 30 m running test to obtain speed data, during the pre-test and post-test. Then the data was analyzed using the SPSS 25 series. Group I data includes: leg muscle explosive power increased by 8,370%, strength increased by 8.768%, speed increased by 1.18%. Group II includes: leg muscle explosive power increased 7.288%, strength increased 7.915%, speed increased 0.989%. Group III includes: leg muscle explosive power increased by 6.672%, strength increased by 9.794%, speed increased by 0.880%. Group IV includes: leg muscle explosive power increased by 6.476%, strength increased by 9.542%, speed increased by 0.928%.

The above results can be concluded; (1) There is an influence of Squat Jump Cone training on leg muscle explosive power, strength and speed (2) There is an influence of Lateral Trapping Jump Cone training on leg muscle explosive power, strength and speed (3) There is an influence of Lateral Trapping Jump Drill  training on explosive power leg muscles, strength and speed of leg muscles. (4) There is an effect of Trapping Jump Drill leg muscle strength, speed and training on leg muscle explosive power.
