Abstract

Penelitian ini menggunakan metode kuantitatif dengan pendekatan survei dan analisis jalur (path analysis). Populasi penelitian adalah siswa kelas XI SMA Negeri 59 Jakarta dengan jumlah sampel sebanyak 80 siswa yang dipilih menggunakan teknik simple random sampling. Instrumen yang digunakan meliputi kuesioner Physical Activity Questionnaire for Adolescents (PAQ-A) untuk mengukur aktivitas fisik, instrumen Social Media Use Integration Scale (SMUIS) untuk intensitas penggunaan media sosial, instrumen Adolescents Sleep-Wake Scale (SWAS) untuk mengukur kualitas tidur, serta Tes Kebugaran Jasmani Indonesia (TKJI) untuk mengukur kebugaran jasmani. Hasil penelitian menunjukkan bahwa: (1) aktivitas fisik berpengaruh positif dan signifikan terhadap kebugaran jasmani; (2) intensitas penggunaan media sosial berpengaruh negatif dan signifikan terhadap kebugaran jasmani; (3) kualitas tidur berpengaruh positif dan signifikan terhadap kebugaran jasmani; (4) aktivitas fisik berpengaruh positif dan signifikan terhadap kualitas tidur; (5) intensitas penggunaan media sosial berpengaruh negatif dan signifikan terhadap kualitas tidur; (6) aktivitas fisik berpengaruh tidak langsung terhadap kebugaran jasmani melalui kualitas tidur; dan (7) intensitas penggunaan media sosial berpengaruh tidak langsung terhadap kebugaran jasmani melalui kualitas tidur. Dengan demikian, kualitas tidur terbukti berperan sebagai variabel mediasi dalam hubungan antara aktivitas fisik dan penggunaan media sosial dengan kebugaran jasmani siswa. Implikasi penelitian ini menunjukkan bahwa peningkatan aktivitas fisik, pengendalian penggunaan media sosial, dan perbaikan kualitas tidur perlu menjadi perhatian sekolah, guru PJOK, dan orang tua dalam upaya meningkatkan kebugaran jasmani siswa. Kata kunci: aktivitas fisik, media sosial, kualitas tidur, kebugaran jasmani, siswa SMA.  *****ABSTRACT This study aims to determine the direct and indirect effects of physical activity, intensity of social media use, and sleep quality on physical fitness in grade XI students of SMA Negeri 59 Jakarta. The research is motivated by low levels of physical activity, high use of social media, and decreased sleep quality that have the potential to affect the level of physical fitness of students. This study uses a quantitative method with a survey approach and path analysis. The study population was grade XI students of SMA Negeri 59 Jakarta with a sample of 80 students selected using a simple random sampling technique. The instruments used included the Physical Activity Questionnaire for Adolescents (PAQ-A) questionnaire to measure physical activity, the Social Media Use Integration Scale (SMUIS) instrument for the intensity of social media use, the Adolescents Sleep-Wake Scale (SWAS) instrument to measure sleep quality, and the Indonesian Physical Fitness Test (TKJI) to measure physical fitness. The results of the study indicate that: (1) physical activity has a positive and significant effect on physical fitness; (2) the intensity of social media use has a negative and significant effect on physical fitness; (3) sleep quality has a positive and significant effect on physical fitness; (4) physical activity has a positive and significant effect on sleep quality; (5) intensity of social media use has a negative and significant effect on sleep quality; (6) physical activity has an indirect effect on physical fitness through sleep quality; and (7) intensity of social media use has an indirect effect on physical fitness through sleep quality. Thus, sleep quality has been shown to act as a mediating variable in the relationship between physical activity and social media use and students' physical fitness. The implications of this study suggest that increasing physical activity, controlling social media use, and improving sleep quality need to be addressed by schools, physical education teachers, and parents in efforts to improve students' physical fitness. Keywords: Physical Activity, Intensity of Social Media Use, Sleep Quality, Physical Fitness, High School Students
