PENGARUH KONSUMSI AIR MINUM REVERSE OSMOSIS (RO) TERHADAP LAJU ALIRAN, pH, DAN VISKOSITAS SALIVA PADA SISWA SMA NEGERI 10 FAJAR HARAPAN BANDA ACEH

Abstract

One drink that is processed by the reverse osmosis method is Reverse Osmosis (RO) drinking water.
Through this method, all micro particles contained in filtered water including essential minerals. The
reduction in essential minerals can reduce the activation function of salivary gland secretory cells
and it will have an impact on salivary flow, pH, and viscosity. This study aims to determine the effect
of RO drinking water consumption to the flow rate, pH, and viscosity of saliva on students of Fajar
Harapan Senior High School Banda Aceh. The study subjects consisted of 45 subjects who consumed
RO drinking water as the treatment group and 8 subjects who did not consume RO drinking water as
a control group. Saliva from the treatment and control group subjects was collected by spitting
method to measure the flow rate, pH, and viscosity of saliva. The results of the study that were
analyzed using the unpaired T test showed that there was no effect of RO drinking water consumption
on the flow rate, pH, and viscosity of saliva in SMA Negeri 10 Fajar Harapan Banda Aceh. Based on
the results of the research, it can be concluded that the consumption of RO drinking water does not
affect the flow rate, pH and viscosity of the saliva in students of Fajar Harapan Senior High School
Banda Aceh.
