Abstract

The first step in the management of coastal pollution in the coastal area of Sukabumi Regency is the assessment of the pollution status of the two rivers, namely the Cipalabuan River and the Cipanyairan River, which is part of the integrated coastal management programme of Sukabumi Regency. Based on calculation of 35 water quality parameters shows that Cipanyairan River was considered heavily polluted with pollution index (PI) more than 10, characterized by low pH, low dissolved oxygen (DO), and high BOD, COD, TP, NO2, Cd, Pb, Mn, Cl2, total coliform, and fecal coliform. Meanwhile, water quality in Cipalabuhan River was better than Cipanyairan River, stated as moderately polluted with PI between 5 to 10, characterized by COD, Total Phosphorus, Co, Cd, and Pb. The higher water discharge in Cipalabuhan compared to Cipanyairan may had been the factor causing the better water quality in Cipalabuhan River. High concentration of Total P shows that human daily activities such as laundry and domestic wastes. Calculation on pollution load capacity shows that Cipanyairan has been shown for its higher value compared to that of Cipalabuhan, i.e for BOD5, the pollution load in Cipanyairan and Cipalabuhan are -102.64 kg/day and 2.74 kg/day, respectively.
