Abstract
Penelitian ini memiliki tujuan untuk menganalisis hubungan aktivitas fisik harian serta penerapan pedoman gizi seimbang terhadap tingkat kebugaran jasmani peserta didik kelas VIII SMP Negeri 71 Jakarta. Lokasi penelitian berada pada SMP Negeri 71 Jakarta pada tahun 2026. Metode penelitian yang digunakan merupakan pendekatan kuantitatif yang bersifat kausal melalui teknik analisis regresi linear berganda. Populasi penelitian mencakup seluruh siswa kelas VIII SMP Negeri 71 Jakarta sejumlah 180 siswa. Sampel penelitian terdiri atas 71 siswa yang diperoleh melalui teknik stratified cluster sampling. Pengumpulan data dilaksanakan melalui kuesioner International Physical Activity Questionnaire Short Form (IPAQ-SF) guna mengukur aktivitas fisik harian (X1), kuesioner penerapan pedoman gizi seimbang untuk menilai penerapan pedoman gizi seimbang (X2), serta Tes Kesegaran Jasmani Indonesia (TKJI) untuk mengukur tingkat kebugaran jasmani (Y). Hasil penelitian menunjukkan bahwa, pertama, terdapat hubungan yang signifikan antara aktivitas fisik harian terhadap kebugaran jasmani siswa melalui nilai signifikansi 0,014 lebih kecil daripada 0,05. Kedua, terdapat hubungan signifikan antara penerapan pedoman gizi seimbang terhadap kebugaran jasmani siswa melalui nilai signifikansi 0,021 lebih kecil daripada 0,05. Ketiga, terdapat hubungan signifikan antara aktivitas fisik harian serta penerapan pedoman gizi seimbang secara simultan terhadap kebugaran jasmani siswa melalui nilai signifikansi kurang dari 0,001 lebih kecil daripada 0,05. Nilai koefisien determinasi sebesar 0,198 menunjukkan bahwa kedua variabel bebas secara simultan memberikan kontribusi sebesar 19,8 persen terhadap kebugaran jasmani siswa, sedangkan 80,2 persen sisanya dipengaruhi oleh faktor lain di luar penelitian ini.*****This study aims to analyze the influence of daily physical activity and the application of balanced nutrition guidelines on the physical fitness levels of 8th-grade students at SMP Negeri 71 Jakarta. The research was conducted at SMP Negeri 71 Jakarta in 2026. A quantitative causal research approach was employed, utilizing multiple linear regression analysis. The study population comprised all 180 8th-grade students at SMP Negeri 71 Jakarta. The sample consisted of 71 students selected via stratified cluster sampling. Data collection involved the International Physical Activity Questionnaire Short Form (IPAQ-SF) to measure daily physical activity (X1), a questionnaire on the application of balanced nutrition guidelines (X2), and the Indonesian Physical Fitness Test (TKJI) to measure physical fitness levels (Y). The results indicate that, first, there is a significant influence of daily physical activity on student physical fitness, with a significance value of 0.014 (less than 0.05). Second, there is a significant influence of the application of balanced nutrition guidelines on student physical fitness, with a significance value of 0.021 (less than 0.05). Third, there is a significant simultaneous influence of daily physical activity and the application of balanced nutrition guidelines on student physical fitness, with a significance value of less than 0.001 (less than 0.05). The coefficient of determination (R-squared) of 0.198 indicates that the two independent variables simultaneously contribute 19.8 percent to student physical fitness, while the remaining 80.2 percent is influenced by factors outside the scope of this study.
