Abstract
Kemayungan-Linduk coastal area is located in Banten Bay (Banten Province), with various activities, including aquaculture and capture fisheries. This research was aimed to determine coastal water quality in the area through the Nemerow s Pollution Index (PI) calculation in the context of fisheries development. The water quality was observed by direct mesurements in the field and sample water collections from February to April 2021 at six stations. The water quality parameters observed was temperature, transparency, turbidity, TSS, pH, salinity, dissolved oxygen (DO), nitrite, nitrate, ammonia, and dissolved phosphate. The Pollution Index (PI) was used to determine the water quality or aquatic pollution state for fisheries. The results indicate that water quality of Kemayungan-Linduk coast was considered fairly good with temperature ranged from 29-33 degree C- transparency 20-110 cm, turbidity 2.8-99.0 NTU, pH values 6.7- 8.0, salinity 0-33 o/oo, DO 2.3-7.3 mg/L, nitrite 0.006-0.17 mg/L, nitrate 0.001-1.63 mg/L, and phosphate 0.001-0.40 mg/L. The PI values of all observation stations ranged from 1.30 to 4.88 indicating that the status of the water quality is lightly polluted. Based on this study, therefore, the Kemayungan-Linduk coastal water is categorized as suitable for fisheries development.
