Sleep disorder is one of the severe health problems that often occur in 60 years old or above. The consumption of fruits with high tryptophan and melatonin content can decrease sleep disorder. Banana is one of the fruits that contain tryptophan and melatonin. This study aimed to determine the effect of banana consumption on the symptoms of sleep disorders in the elderly. The study is experimental research with pre and post-test control design. Sixty-three samples were selected randomly and divided into three groups (n=21): control group, treatment group 1 received 130 grams banana/day (PI), and treatment group 2 received 260 grams banana/day (PII). All treatment group were treated with banana for 14 days. The sleep disorders were measured by using IRS (Insomnia Rate Scale) 3 times before the study, and at day-7 and day-14 during the study. Statistical analysis was performed by using One Way ANOVA test and continued with Post Hoc test. Then, data were examined using Repeated Measure to determine the difference among the durations of administration. There was a decrease in sleep disorders from the beginning of the study (day-7) until the end of the study (day-14) in PI and PII group. PII group was found to have a high decrease with a value of 2.50 points. This study suggested that the administration of banana could reduce sleep disorders in the elderly and can be considered as an alternative supplement to reduce sleep disorders in the elderly.
