Abstract

Penelitian ini bertujuan menganalisis validitas dan reliabilitas Chronojump (flight time), OVR Laser System (sensor laser), dan metode konvensional (jump-and-reach) dalam pengukuran vertical jump. Metode comparative study dengan 30 mahasiswa laki-laki FIKK UNJ (17-24 tahun) melalui purposive sampling. Setiap subjek melakukan tiga percobaan per metode, interval satu menit. Analisis menggunakan Pearson Product Moment (validitas) dan Cronbach's Alpha (reliabilitas). Hasil: validitas sangat tinggi dengan korelasi T1-T3 terhadap total Chronojump (r=0,990- 0,992), OVR (r=0,990-0,995), konvensional (r=0,987-0,988), p<0,01. Reliabilitas excellent: Chronojump (α=0,991), OVR (α=0,992), konvensional (α=0,987). Korelasi antar metode: Chronojump-OVR (r=0,930), Chronojump-Konvensional (r=0,886), OVR-Konvensional (r=0,817). OVR memiliki konsistensi tertinggi (SD=5,61). Perbedaan rata-rata: konvensional (56,66 cm), OVR (48,54 cm), Chronojump (38,48 cm) mencerminkan perbedaan mekanisme pengukuran. Kesimpulan: ketiga metode memiliki kualitas psikometris sangat baik dan reliabel untuk mengukur vertical jump. Kata kunci: Vertical Jump, Chronojump, OVR Laser System, Metode Konvensional ***** This study aims to analyze the validity and reliability of Chronojump (flight time), OVR Laser System (laser sensor), and conventional methods (jump-and-reach) in measuring vertical jump. A comparative study method was used with 30 male students from FIKK UNJ (aged 17-24 years) through purposive sampling. Each subject performed three trials per method, with a one-minute interval between trials. Analysis was performed using Pearson Product Moment (validity) and Cronbach's Alpha (reliability). Results: Very high validity with T1-T3 correlations against total Chronojump (r=0.990-0.992), OVR (r=0.990-0.995), conventional (r=0.987-0.988), p<0.01. Reliability was excellent: Chronojump (α=0.991), OVR (α=0.992), conventional (α=0.987). Correlation between methods: Chronojump-OVR (r=0.930), ChronojumpConventional (r=0.886), OVR-Conventional (r=0.817). OVR has the highest consistency (SD=5.61). Average differences: conventional (56.66 cm), OVR (48.54 cm), Chronojump (38.48 cm) reflect differences in measurement mechanisms. Conclusion: all three methods have excellent psychometric quality and are reliable for measuring vertical jump. Keywords: Vertical Jump, Chronojump, OVR Laser System, Conventional Method
