The students who were not used to drinking the 
highest amounts of coffee were given a mild pain of 
25 (25%). Whereas the girls with the highest 
concentration of coffee habits had 29 mild pains 
(29%). Based on the chart above by using the chi-
square exam, it got an asymptotic margin of 0.248. 
Because of the asymptotic dysmenial value 0.248 > 
0.05, there is no significant connection between the 
drinking of coffee with dysmenorrhea pain

This study shows that 87% of students are 
dominated by the chronotype morning compared to 
the chronotypes that have the chronotypes by night. 
This is in line with the afghaniy research (2013) in 
high school children who tend to be dominated by 
children who have chronotypes by morning. It can 
also be influenced by a school schedule in the 
morning so that one is required to be active in the 
morning because of having to participate in teaching 
activities. 
Based on the dysmenorrhea pain chart, the result 
is that only 7 people (7%) did not feel pain during 
dysmenorrhea while 93 people (93%) felt pain. 
Menstrual pain often occurs in young women because 
they not reaching biological maturity (particularly 
those of the reproductive apparatus of endometrium 
growth are still rudimentary. (Rustam,2015) 
Whereas the results seen in the cross chart 
between chronotypes with degrees of dysmenorrhea 
pain suggest that there is a meaningful connection 
between chronotypes with degrees of dysmenorrhea. 
The student with the dominant chronotype received 
mild pain by 57 people (50%). Chronotypes are 
closely associated with circadian rhythm or biological 
rhythm. Biological rhythms play an important role in 
reproductive regulation such as in regulating the 
production, release, synthesis, and operation of 
hormone reproductive tools. Night sleep turned into a 
reason for symptoms of menstruation to rise (negriffs, 
2011). Therefore when bedtime is not disturbed, 
menstrual symptoms such as dysmenorrhea can be 
reduced. 
The table of drinking habits shows that 52% of 
girls do not have the habit of drinking coffee with 25 
(25%) girls suffering moderate pain. While 48% of 
the students who drank coffee were physically ill with 
as many as 29 people (29%). Based on the cross-chart 
of coffee habits with dysmenorrhea pain indicates 
there was no meaningful connection between of both. 
Minor pain experienced by adolescents who 
habitually drink coffee can be affected by caffeine 
consumption limits daily. High caffeine intake is 
over-defined if caffeine consumption exceeds 
prescribed encouragement. 
In the study, researchers have also found that 
research limits have been found that researchers have 
lost control of the design factors, such as stress, sleep 
quality, and other foods that may affect menstrual 
dysmenorrhea pain.

CONCLUSIONS 
Based on the results it was determined that there was 
a relationship between chronotype and dysmenorrhea 
pain in the SMAN 1 Kesamben Blitar, but there was 
no substantial correlation between the drinking of 
coffee and the degree of dysmenorrhea pain. 
Adolescents with morning chronotypes tend to 
develop degrees of mild pain at dysmenorrhea
