Abstract

Cisadane watersheds is a very valuable strategicarea for the people in Tangerang District, Banten, Indonesia.But that strategic value has brings an impact in the form ofwater pollution, that comes from its popullation and economicactivities. This water pollution load is necessary to know itssource, and also how much, so that public, private and localgovernments can jointly take action to restore the water qualityof the Cidasane River. The purpose of this study is to determinethe pollution load in the Cidasane watersheds. The study willtaking sample of Cisadane River water as an inputs in the isoyetmap pollution dispersion modeling. And calculating the load inthe river using QUAL2Kw modelling. The results of themodeling are then analyzed to obtain the amount of CisadaneRiver pollutant load. The pollution load in this study will befocused on BOD, NO3, and Total P, and Salinity. This researchhas shown the inter-regional pollution spread on the Cisadaneriver, which used This study will provide a measurable data ofthe type and scale of the pollution load in Cisadane, as an inputfor Cisadane River water quality restoration policy making bythe Government of Tangerang.
