Abstract

Abstrak
Penelitian ini bertujuan untuk mengetahui nilai validitas dan reliabilitas instrumen kelincahan
balsom agility test terhadap atlet Sekolah Menengah Pertama Kelas Khusus Olahraga di Daerah
Istimewa Yogyakarta. Penelitian ini merupakan penelitian deskriptif dan teknik pengumpulan data
menggunakan  metode tes dan pengukuran. Populasi dalam penelitian ini adalah atlet Sekolah
Menengah Pertama Kelas Khusus Olahraga di Daerah Istimewa Yogyakarta. Sampel yang digunakan
dalam penelitian sejumlah 80 atlet. Teknik pengambilan sampel dalam penelitian ini menggunakan
cluster sampling. Instrumen yang digunakan adalah balsom agility test dan shuttle run untuk
mengukur kelincahan atlet. Analisis data uji validitas menggunakan korelasi product moment dan
reliabilitas menggunakan teknik estimasi test-retest. Hasil penelitian menunjukan bahwa tingkat
validitas sebesar 0,639 termasuk kategori kuat. Tingkat reliabilitas sebesar 0.905 termasuk kategori
sangat kuat. Hasil ini menunjukan bahwa nilai validitas dan reliabilitas balsom agility test signifikan.

This research aimed to know the validity and reliability value of Balsom Agility  Test to
Specification Class Sport of Junior High School athletes at Special Region of Yogyakarta. This
research is a descriptive and the technique of collecting data using test and measurement. The
population of this research was all of Specification Class Sport of Junior High School athletes at
Special Region of Yogyakarta. The number of the sample was 80 athletes. Cluster sampling was the
chosen sampling method. Balsom Agility Test and Shuttle Run were used to measure athletes agility.
Data of validity test were analyzed by product moment correlation and data of reliability were
analyzed by test-retest estimation  technic. Results of the research showed validity level as 0,639
which included as strong category. Reliability level was counted  as 0,905 which included as very
stong category. This results showed that validity and reliability of Balsom Agility Test was significant.
