Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh big five personality trait terhadap bedtime procrastination (BP) pada individu dewasa awal. Tingginya angka kurang tidur pada kelompok usia ini sering kali didorong oleh kegagalan regulasi diri dalam menunda waktu tidur secara sengaja. Metode yang digunakan dalam penelitian ini adalah pendekatan kuantitatif korelasional melalui survei. Partisipan terdiri dari 316 orang dewasa awal (rentang usia 18-40 tahun) yang dipilih menggunakan teknik purposive sampling. Pengumpulan data dilakukan menggunakan instrumen Bedtime Procrastination Scale (BPS) dan Big Five Inventory-2 (BFI-2). Analisis data statistik menggunakan uji regresi linear berganda. Hasil penelitian menunjukkan bahwa secara simultan, kelima dimensi big five personality trait berpengaruh secara signifikan terhadap BP. Secara parsial, dimensi conscientiousness memberikan pengaruh negatif yang signifikan, sedangkan negative emotionality memberikan pengaruh positif yang signifikan terhadap RBP. Di sisi lain, dimensi open mindedness, extraversion, dan agreeableness tidak memiliki pengaruh yang signifikan. Kontribusi seluruh dimensi kepribadian tersebut terhadap BP adalah sebesar 13,9%, sementara 86,1% sisanya dipengaruhi oleh faktor lain di luar penelitian. Kata kunci: Dewasa Awal, Big Five Personality Trait, Bedtime Procrastination, Kualitas Tidur. ***** This study aims to examine the effect of the big five personality traits on bedtime procrastination (BP) among young adults. The high prevalence of sleep deprivation in this age group is often driven by self-regulation failures in intentionally delaying sleep. A quantitative correlational survey method was employed for this study. The participants consisted of 316 young adults (aged 18-40 years) selected through a purposive sampling technique. Data were collected using the Bedtime procrastination Scale (BPS) and the Big Five Inventory-2 (BFI-2). Data analysis was conducted using multiple linear regression. The results indicated that, simultaneously, the big five personality traits significantly influence BP. Partially, the conscientiousness dimension exhibited a significant negative effect, while negative emotionality showed a significant positive effect on BP. Conversely, open-mindedness, extraversion, and agreeableness showed no significant impact. The effective contribution of these personality traits to BP was 13.9%, leaving 86.1% influenced by other factors not examined in this study. Keyword: Young Adult, Big Five Personality Trait, Bedtime Procrastination, Sleep Quality.
