is due to the safety factors, namely 63.1 in the highland area and 80.4 in the lowland.
6. About half of teenage and adult subjects 42.4 – 49.7 both in the highland and the lowland having lack of knowledge on healthy drinking water. The two subject groups
are mostly inadequate knowledge on the aspect of the function of water, food as source of water, and dehydration symptoms.
7. Dehydration for both teenagers and adults in this study is categorized as mild dehydration. The prevalence of the teenagers with mild dehydration is 24.75 in the
highland area and 41.67 in the lowland. Meanwhile, the mild dehydration for the adult group is 15.40 and 24.05 respectively. The prevalence of mild dehydration
in the two groups of subjects is higher in the lowland compare to the highland area.
5.2. Recommendations
1. About half of the teenagers and adults having low knowledge on healthy drinking water. Therefore, all stakeholders including the government, education institution and
also the related industries should be actively promote or educate the public on healthy drinking water.
2. The government and education institutions such as schools and universities could increase the student’s knowledge on healthy water drinking through the class meeting
or extra-curricular activities. 3. The private industries could educate the consumers through various commercial
advertisement of the product in the mass-media, campaign, seminar, workshop, and also by exposing related information in the product packaging on healthy drinking
water. 4. Further similar studies are required in other regions of Indonesia on the same age
groups teenagers and adults and other age groups child, elderly, and pregnant woman.
5. A study on school based approach for preventing dehydration among students is also required.
