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

Abstract

Abstract
Crucial Issues at 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 Dailly Load (TMDL)in Ciujung River as a basis for determining
river pollution control strategies. TMDL of BOD determined by modeling WASP (Water
quality Analysis Simulation Program) and the results were compared with the standar
streams due to PP No.82/2001. Water pollution control strategies of Ciujung River determined
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 13.5 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 (27.5km) can meet the 4th class of river
quality standard with average TMDL 21,241.74 kg/day. whereas downstream areas, which
do not meet 4th class of quality standards along 4.5 km. Alternative strategies of Ciujung
rivers water pollution control with the aim of reducing the pollution load is tightening
licensing waste disposal (eigen value 0.260).
