Abstract 

Simultaneous analysis of unconfined aquifer in Pekanbaru city should consider environment factors such as additive, etika, and government intervention factors. The additive factor of 5% and biocentricetika factor of 70% contribute to the correction of unconfined aquifer in the safe condition with percentage deviation of 40.57% and 11.02% respectively for year of 2013 and 2014. The additice factor of 5% and biocentricetika of 70% in 2015 contribute to the head-hydrolic deviation of -29.62% which means still in safe condition.However, the additive factor of 8% will contribute a correction to head hydrolikof unconfinedaquiferin 2016, 2017, and 2018. It also sucsessfully improve unconfinedaquifer condition from a shortages condition to the safe condition (-29.41%) in 2016, from a critical condition to the shortages condition (48.97%) in 2017 and from a demaged condition to the critical condition (-63.76%) in 2018. Certainly, additive factor of 8% and biocentric of 70% supported by government statement of industry sectorial only allowed consuming water of 75% from the unconfinedaquifer will contribute to the safe condition in 2017 and 2018 with the reduction percentage of the unconfinedaquifer from the natural condition is -19.15% and -32.85% respectively.
