IDENTIFIKASI DAYA TAMPUNG BEBAN PENCEMARAN SUNGAI CIUJUNG DENGAN MODEL WASP DAN STRATEGI PENGENDALIANNYA

Abstract

Crucial Issuesa t the downstream Ciujung river is the increasing load of-water pollution' BOD is one of the water pollution indicator in the stream.This study aimed to determine the amount of Total Maximum Daily Load (TMDL) in Ciuiung River as a basis for determining river pollution control strategies. TMDL of BOD determined by nodeling WASP (Water quality Analysis & Simulation Program) ond the results were compared with the standar streams due to pp No.82/200l. Water pollution control strategies of Ciujung River. deterniined by analysis of the results of an expert survey method with AHP( Analytical Hierarchy Process). The results showed that the water quality of Ciujung rivers at minimum reliable discharge meets the river standard of 4th class along the I3,5 km' Simulation results at maximum reliable discharge and reduction of point source, pollution load by 90% indicates that the water quality in the segment Nagara to Tirtayasa (27.5 km) can meet he 4th class of river quality standard with average TMDL 21,241.74 kg/day. where as downstream areas, which do not meet 4th class of quality standards along 1.5 km. Alternative strategies of Ciujung rivers water pollution control with the aim o/ reducing the pollution load is tightening licensing waste disposal (eigen value 0,260)
