        abstract = {Pendahuluan: Lansia sering mengalami penurunan kualitas tidur yang dapat berdampak
buruk pada fungsi kognitif. Gangguan tidur seperti sulit tidur, sering terbangun, dan bangun
terlalu pagi dapat mempercepat penurunan daya ingat dan kemampuan berpikir. Tujuan:
Penelitian ini secara umum bertujuan untuk mengetahui hubungan antara kualitas tidur
dengan fungsi kognitif pada lanjut usia. Metode Penelitian: Penelitian ini menggunakan
desain cross sectional dengan pendekatan kuantitatif. Sebanyak 60 lansia menjadi
responden. Instrumen GSQ-6 digunakan untuk menilai kualitas tidur, dan IQCODE untuk
fungsi kognitif. Analisis data dilakukan menggunakan uji korelasi Spearman untuk
mengetahui hubungan antara kualitas tidur dan fungsi kognitif. Analisis dilakukan dengan
uji korelasi. Hasil dan Pembahasan: Ditemukan hubungan yang sangat signifikan antara
kualitas tidur dan fungsi kognitif (p{\ensuremath{<}}0,001; {\ensuremath{\alpha}} {$\leq$} 0,05) dengan koefisien korelasi 0,79.
Semakin buruk kualitas tidur, semakin menurun fungsi kognitif. Simpulan: Kualitas tidur
yang buruk berkontribusi terhadap penurunan fungsi kognitif lansia. Intervensi peningkatan
kualitas tidur penting dilakukan sebagai upaya preventif dalam menjaga kesehatan kognitif
dan kualitas hidup lansia. 

Introduction: Elderly often experience a decline in sleep quality which can adversely affect
cognitive function. Sleep disturbances such as difficulty falling asleep, frequent
awakenings, and early morning awakening may accelerate deterioration in memory and
thinking abilities. Objective: The aim of this study is to examine the relationship between
sleep quality and cognitive function in the elderly population. Research Method: This study
employed a cross-sectional design with quantitative methods, involving 60 elderly
participants. Sleep quality was assessed using the GSQ-6 (Geriatric Sleep Questionnaire-
6) instrument, while cognitive function was measured with the IQCODE (Informant
Questionnaire on Cognitive Decline in the Elderly). Data analysis was conducted using the
spearman correlation test to determine the relationship between sleep quality and cognitive
function. Results and Discussion: Correlation analysis revealed a highly significant
relationship between sleep quality and cognitive function (p{\ensuremath{<}}0.001; {\ensuremath{\alpha}} {$\leq$} 0.05), with a
strong correlation coefficient of 0.79. The findings demonstrate that poorer sleep quality is
associated with greater cognitive decline, indicating that sleep disturbances significantly
contribute to worsening cognitive function in the elderly. Conclusion: These results
highlight the importance of sleep quality interventions as a preventive measure to maintain
cognitive health and improve quality of life in aging populations.},
