ABSTRACT
The Batulicin River is one of the rivers used by the community for various activities in Tanah Bumbu Regency. In order to obtain a simulation scenario for the management of the Batulicin River, a study was carried out on the water quality of the Batulicin River, as well as modeling using the WASP method. The water quality of the Batulicin River is known with reference to Government Regulation of the Republic of Indonesia Number 22 of 2021 Appendix VI. Selection of the most optimal scenario for reducing the BOD pollution load on the Batulicin River is by referring to Scenarios 3, 4 and 5. The process in Scenarios 3, 4 and 5 is carried out by reducing the BOD pollution load respectively, namely 5549.10 kg/day, 5895.61 kg/day and 6789.96 kg/day. Management of river water quality in terms of BOD parameters, the most optimal is carried out through scenario 5, namely reducing pollutant materials from community's domestic activities by 95.85%, industrial activities by 50% and plantation activities by 50%, so that water quality is obtained against the BOD parameter at All segments of the Batulicin River meet class 1 and 2 water quality standards.
