Validitas Aiken’s instrumen tes untuk mengukur reaktif agility olahraga khusus tenis meja

Abstract

Instrumen pengukuran reaktif agility sangat diperlukan oleh beberapa cabang olaharga termasuk tenis meja, tetapi kenyataan belum ada instrument pengukuran reaktif agility untuk olahraga tenis meja. Tujuan penelitian ini adalah untuk menguji validitas Aiken’s dan menguji reliabilitas antar rater instrumen pengukuran reaktif agility olaharaga khusus tenis meja.  Metode research and development yang dipergunakan  dalam penelitian ini yaitu model 3D yang merupakan modifikasi model dari Thiagarajan yaitu Develop, dengan pendekatan campuran kualitatif dan kuantitatif. Partisipan adalah dokumen dan seoarang ahli. Pengumpulan data menggunakan teknik literature reviews dengan tipe narrative review, kemudian dilanjutkan dengan FGD dan teknik delphi. Instrumen penelitian menggunaka koesioner dengan skala rating 1 sampai 4. Analisis data menggunakan formula Aiken’s untuk uji konten validitas dan  Cronbach's Alpha maupun intraclass correlation  coefficients (ICC) untuk uji reliabilitas antar rater. Hasil penelitian menunujukkan nilai koefisien Aiken’s V di atas 0,76, maka dapat dikatakan bahwa semua aspek valid. Selain itu, juga dihasilkan nilai Cronbach's Alpha dan ICC sebesar 0,875, maka dapat dikatakan bahwa instrument ini cukup andal. Dengan demikian, dapat disimpulkan bahwa instrument pengukuran reaktif agility olahraga khusus tenis meja memiliki validitas Aiken cukup tinggi, dan reliabilitas antar rater cukup kuat. Aiken’s Validity of test instrument for measuring the reactive agility of table tennis AbstractThe reactive agility measurement instrument is strongly needed by several sports, including table tennis. Nevertheless, there has no reactive agility measurement instrument used in table tennis. This research is aimed at testing the Aiken’s validity and the inter-rater reliability of the reactive agility measurement instrument in table tennis. The research and development (R&D) method used in this study refers to the 3D model, which is a modification model from Thiagarajan, including Develop, using a mixed approach of qualitative and quantitative. The participants were documents and an expert. Data were collected using a literature review technique with a narrative review, then proceeded with FGD and Delphi technique. The research instrument used was a questionnaire with a rating scale of 1 to 4. Data were analyzed using Aiken’s formula to test the content validity and Cronbach’s Alpha as well as intraclass correlation coefficient (ICC) to test the inter-rater reliability. The research result shows that the Aiken’s V coefficient value is above 0.76, indicating that all aspects are valid. Furthermore, Cronbach’s Alpha and ICC value are 0.875, indicating that the instrument is quite reliable. Therefore, it is concluded that the reactive agility measurement instrument for table tennis has a quite high Aiken validity and a quite strong inter-rater reliability.
