Abstract

Penggunaan telepon pintar sebelum tidur dapat mengurangi waktu yang tersedia untuk tidur dan berpotensi berkaitan dengan rasa kantuk pada siang hari. Penelitian ini bertujuan untuk mengestimasi rata-rata durasi scrolling sebelum tidur serta menganalisis hubungannya dengan tingkat kantuk mahasiswa matematika setelah memperhitungkan durasi tidur dan konsumsi kafein setelah pukul 18.00. Penelitian ini menggunakan pendekatan kuantitatif dengan desain observasional dan data kuesioner dari 45 mahasiswa matematika Universitas Negeri Medan. Estimasi durasi scrolling dilakukan menggunakan rata-rata sampel dan interval kepercayaan 95% berdasarkan distribusi t-Student. Hubungan antarvariabel dianalisis menggunakan regresi linear berganda dengan metode ordinary least squares (OLS), sedangkan tingkat kantuk diukur menggunakan Epworth Sleepiness Scale (ESS). Hasil penelitian menunjukkan bahwa rata-rata durasi scrolling sebelum tidur adalah 52,57 menit, dengan simpangan baku 32,05 menit dan interval kepercayaan 95% sebesar 42,94–62,20 menit. Hasil regresi menunjukkan bahwa durasi tidur memiliki hubungan parsial negatif yang signifikan dengan tingkat kantuk, sedangkan konsumsi kafein setelah pukul 18.00 memiliki hubungan parsial positif yang signifikan. Sebaliknya, durasi scrolling tidak menunjukkan hubungan parsial yang signifikan dengan tingkat kantuk setelah variabel lainnya dikendalikan. Model regresi secara keseluruhan signifikan, dengan koefisien determinasi ((R^2)) sebesar 0,436 dan koefisien determinasi terkoreksi sebesar 0,395. Temuan ini menunjukkan bahwa durasi tidur dan konsumsi kafein pada malam hari berhubungan secara signifikan dengan tingkat kantuk dalam model yang digunakan. Namun, desain observasional dan penggunaan data kuesioner membatasi penarikan kesimpulan kausal.
