Abstract

Penelitian ini dilatar belakangi oleh pentingnya kualitas tidur dan konsentrasi dalam menunjang performa bertanding atlet taekwondo. Penelitian ini bertujuan untuk mengetahui hubungan kualitas tidur dan konsentrasi terhadap performa bertanding atlet Taekwondo Universitas Negeri Jakarta. Penelitian ini menggunakan metode kuantitatif dengan desain korelasional. Sampel penelitian berjumlah 10 atlet yang dipilih menggunakan teknik purposive sampling. Instrumen yang digunakan meliputi Pittsburgh Sleep Quality Index (PSQI), tes konsentrasi, dan lembar observasi performa bertanding yang telah diuji validitas oleh ahli serta reliabilitas menggunakan Intraclass Correlation Coefficient (ICC). Analisis data menggunakan korelasi Pearson dan regresi linear berganda. Hasil penelitian menunjukkan terdapat hubungan negatif yang signifikan antara kualitas tidur dengan performa bertanding (r = -0,635; p = 0,049) dan hubungan positif yang signifikan antara konsentrasi dengan performa bertanding (r = 0,671; p = 0,034). Secara simultan, kualitas tidur dan konsentrasi berhubungan signifikan dengan performa bertanding (R = 0,795; Adjusted R Square = 0,526; p = 0,030). Dengan demikian, kualitas tidur dan konsentrasi memiliki hubungan yang signifikan terhadap performa bertanding atlet Taekwondo Universitas Negeri Jakarta. Kata kunci : kualitas tidur, konsentrasi, performa bertanding, taekwondo ***** This study was motivated by the importance of sleep quality and concentration in supporting the competitive performance of taekwondo athletes. The aim of this study was to determine the relationship between sleep quality and concentration and the competitive performance of taekwondo athletes at Jakarta State University. This study employed a quantitative method with a correlational design. The sample consisted of 10 athletes selected using purposive sampling. The instruments used were the Pittsburgh Sleep Quality Index (PSQI), a Grid Concentration test, and a competitive performance observation sheet, which was validated through expert judgment and tested for reliability using the Intraclass Correlation Coefficient (ICC). Data were analyzed using Pearson's correlation and multiple linear regression. The results showed a significant negative relationship between sleep quality and competitive performance (r = −0.635, p = 0.049) and a significant positive relationship between concentration and competitive performance (r = 0.671, p = 0.034). Multiple linear regression analysis showed that sleep quality and concentration were significantly associated with competitive performance (R = 0.795, Adjusted R² = 0.526, p = 0.030), explaining 52.6% of the variance in competitive performance. In conclusion, sleep quality and concentration were significantly associated with the competitive performance of taekwondo athletes at Jakarta State University. Keywords: sleep quality, concentration, performance, taekwondo
