<![CDATA[The aim of this study was to determine the relationship between the completion of sports facilities and infrastructure and the improvement of basketball extracurricular success at SMP Terpadu Arrisalah.A quantitative strategy using a descriptive correlational approach was used in the investigation. 24 male students who participated in the extracurricular basketball programme made up the population, and 16 students were selected for the sample using purposeful sampling. A Likert-scale questionnaire and documentation were used to gather data. The data analysis employed descriptive statistics, the Shapiro-Wilk normality test, linearity test, Spearman Rank correlation test, simple linear regression analysis, and the coefficient of determination using SPSS version 25. With a significance value of 0.001 (p < 0.05) and a Spearman correlation coefficient of 0.735, the results showed a positive, strong, and significant relationship between the improvement of basketball extracurricular achievement and the completeness of sports facilities and infrastructure. The basic linear regression study's result, Y = 11.070 + 0.769X, showed that extracurricular achievement increased by 0.769 units for every unit rise in the completeness of sports facilities and infrastructure. Additionally, the coefficient of determination (R² = 0.601) showed that sports facilities and infrastructure explained 60.1% of the difference in basketball extracurricular accomplishment, with other factors not included in this study influencing the remaining 39.9%. encouraging the enhancement of school basketball extracurricular performance.Therefore, the completeness of sports facilities and infrastructure is an important factor in supporting the improvement of basketball extracurricular achievement in schools. Consequently, the improvement of basketball extracurricular accomplishment in schools is greatly aided by the completeness of sports facilities and infrastructure.Penelitian ini bertujuan untuk mengetahui hubungan antara kelengkapan sarana dan prasarana olahraga dengan peningkatan prestasi ekstrakurikuler bola basket di SMP Terpadu Arrisalah. Penelitian ini memakai metode kuantitatif dengan pendekatan deskriptif korelasional. Populasi penelitian berjumlah 24 siswa anggota ekstrakurikuler bola basket putra, sedangkan Sampel sebanyak 16 siswa dipilih menggunakan teknik purposive sampling. Data dikumpulkan melalui angket dengan skala Likert serta dokumentasi. Analisis data mencakup statistik deskriptif, uji normalitas Shapiro-Wilk, uji linearitas, uji korelasi Spearman Rank, uji regresi linier sederhana, serta uji koefisien determinasi, yang dilakukan dengan bantuan SPSS versi 25. Hasil penelitian menunjukkan bahwa terdapat hubungan yang positif, kuat, dan signifikan antara kelengkapan sarana dan prasarana olahraga dengan peningkatan prestasi ekstrakurikuler bola basket, Hal ini ditunjukkan oleh koefisien korelasi Spearman sebesar 0,735 dengan nilai signifikansi 0,001 (p<0,05). Analisis regresi linier sederhana menghasilkan persamaan Y = 11,070 + 0,769X, yang mengindikasikan bahwa setiap peningkatan satu satuan kelengkapan sarana dan prasarana diikuti peningkatan prestasi sebesar 0,769 satuan. Nilai koefisien determinasi (R² = 0,601) mengindikasikan bahwa kelengkapan sarana dan prasarana berkontribusi sebesar 60,1% terhadap peningkatan prestasi ekstrakurikuler bola basket, sementara 39,9% lainnya dipengaruhi oleh faktor-faktor di luar penelitian ini. Oleh karena itu, ketersediaan prasarana dan fasilitas olahraga yang memadai merupakan komponen penting yang membantu peningkatan prestasi ekstrakurikuler bola basket di sekolah.]]>
