Abstract
This research aimed to monitor water quality by observing total Persistent Organic Pollutants (PAH, OCP and PCB), total suspended solids (TSS) levels, and the percentage of sediment in Jakarta Bay. The study was carried out in March and May 2013. Surface seawater samples were taken with a water sampler at 16 research stations (8 in the west and 8 in the east). PAH, OCP, and PCB were analysed using chromatographic methods, and TSS was determined using the gravimetric method, while sediment composition was determined using the Wentworth and Shepard method. The stored procedure is used to evaluate the status of seawater quality. The results showed that in the west, PAH average concentration ranges from 7.852-36.518 ppb, in the east from 12.451-108.517 ppb, OCP from 7.660-7.852 ppt, in the east from 5.030-6.444 ppt, and PCBs from 3.680-18.183 ppt, in the east from 2.694-9.817 ppt. This concentration has passed the threshold value stated by the Ministry of Indonesia for marine life. TSS concentration in the west ranged from 20.05-30.414 mg/l, in the east from 23.90-34.55 mg/l, which also exceeds the threshold value for biota. Sediment percentage in the west ranged from 91.767-99.056% and in the east from 99.240-99.999%. All stations' water quality ranged from -1.5 to -10, or the Class B category (light polluted).
