3.5. Data Processing and Analysis
Dehydration determine by criteria such as 1 urine specific gravity 1.020, 2 urine color yellow condensed, 3 eritrosit 1-5lpb, leukocyte 1-5lpb or positive cylinder
hialin, and 4 light proteinuria. Subject who diagnosed has hydration if the subject fullfilled all of dehydration criteria and show two dehydration symptom such as thirsty, dry
throat, headache, flushed skin, dry mouth and lip, rapid heart rate, dizziness, and high concentrated urine but low in volume.
Index for normal category of BMI is range from 18.5 - 23,0 thin CED if less than 18.5 and overweight if more than 23.0 WHO, 2004. Physical activity categorized by US-
DHHS criteria 2008. Low level if time allocation for the medium intensity activity less than 150 minuteweek, medium if the time allocation for medium intensity activity is 150-
300 minuteweek, and high if more than 300 minuteweek. The examples for medium physical activity are fast walk, bike and gardening. Health level obtained if accumulation
of medium physical activity is minimum 30 minute per day WHO, 2003. The electronic file of entry data analyzed statistically by considering the extreme
values to check the validity of entry data. Then the clean data will be analyzed statistically. The results of data analysis will be presented in the form of tables, diagrams
and graphs in order to answer the objective of the study. Mean or proportion different test applied to asses whether the water intake, drinking habit, perception and knowledge,

1.2. Social, Economic and Health Characteristics of Subjects
This research involved two age groups which are teenager and adult group. Each group located in two different ecological areas lowland and highland. The number of
teenagers group in the highland are 97 people consist of 47 boys 48.5 and 50 girls 51.5. Meanwhile, the amounts of the teenagers in the lowland are 109 people consist
of 59 boys 54.1 and 50 girls 45.9. The adult group in the highland are 92 people consist of 37 men 40.2 and 55 woman 59.8. The adult group in the lowland are
102 people consist of 44 men 43.1 and 58 woman 56.9. The number of total subjects is more than the minimum required. The number of
minimum subject required for each location per gender categories are 41 people. This amount is rounded to be 50 people to increase the accuracy of this research. The number
of the adult group is less than the teenagers. To find adult subjects for this research is more difficult than the teenagers. They had to fill in questionnaire and provide urine
samples ±10 ml for urine analynalisis. After screening process, several adult candidates were drop out because they had not required the criteria such as kidney health. However,
in general this research has already met the minimum requirement subject for statistical analysis.
The mean age of teenager group in the highland is 15.9 ± 1.0 year, while in the lowland is 16.0 ± 1.0 year. The age of the teenager’s group range from 15 to 18 years
and this reflect the high school student at grade X, XI and XII. Therefore the teenagers recruited as subjects in this research correctly categorized as a teenager. According to
WHO 1995 teenager age range from 10-19 years. In the adult group, the mean age in the highland is 36.7 ± 8.4 year while in the
lowland is 40.7 ± 9.8 year. The age of the adult group are from 36 up to 50 years. In the subject’s recruitment, the adult subjects must be under 55 years. However, for the most
50-55 years adults had health problems, so they were drop out as a subject. The definition of family is a unit of people living in the same house and having
