Pendekatan Model Wasp Pada Pengendalian Pencemaran Sungai Dengan Parameter Uji Cod

Abstract

<span><em>The rapid development requires enormous natural resources. So it appears that in development there is an </em><span><em>overuse of natural resources, which results in disruption of the water system balance. Various impacts will </em><span><em>occur as a result of unbalanced use of natural resources, the use of unbalanced natural resources around the </em><span><em>Siak river area, causing an increase in pollution entering the river. Regulation of the Minister of PUPR </em><span><em>Number 4 of 2015 concerning Criteria and Designation of River Areas, Siak River is one of the major rivers </em><span><em>that receive national attention and is also included in the national strategic river category. Control of river </em><span><em>pollution is done by analyzing the WASP modeling and the existing condition of the Siak river, the effect of </em><span><em>the levels on the parameters of the mainstay discharge and the mainstay discharge and the percentage of </em><span><em>pollution load reduction carried out to meet the class II quality standards. The results showed that the</em><br /><span><em>overall condition of the Siak river was polluted. The average excess capacity of the COD pollution load at </em><span><em>the time of the depandable discharge is -454,516 kg/day. Then at the time of the depandable discharge is</em><br /><span><em>valued at -181,087 kg/day. The control effort taken is to reduce the COD contamination load so that the </em><span><em>capacity of the pollution load is +177,742 kg/day when the depandable discharge is maximum and +72,536</em><br /><span><em>kg/day when the depandable discharge is minimum. Percentage reduction of COD contamination load at the </em><span><em>minimum and maximum depandable discharge to meet the class II quality standard of 50%.</em></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br /><br class="Apple-interchange-newline" /></span>
