Status Kualitas Air Pantai Kemayungan-Linduk, Teluk Banten Berdasarkan Parameter Fisika dan Kimia Perairan

Abstract

Wilayah pesisir Kemayungan-Linduk terletak di Teluk Banten (Provinsi Banten), merupakan kawasan pemukinan yang memiliki potensi tinggi di berbagai sektor termasuk budidaya perikanan dan perikanan tangkap. Berbagai aktivitas antropogenik dan perubahan alami faktor lingkungan memperngaruhi masuknya bahan pencemar ke dalam perairan sehingga berdampak pada perubahan kondisi kualitas air dan biota di sekitar wilayah perairan tersebut. Penelitian ini bertujuan untuk menganalisis status kualitas perairan pesisir di wilayah Kemayungan-Linduk melalui dua metode, yaitu perhitungan Indeks Pencemaran (IP) dan Indeks CCME (Canadian Council of Ministers of the Environment) dalam rangka pengembangan perikanan. Pengamatan kualitas air dilakukan secara in-situ dan ex-situ dengan pengambilan sampel air pada bulan Februari hingga April 2021 di enam stasiun. Parameter kualitas air yang diamati adalah suhu, kecerahan, kekeruhan, TSS, pH, salinitas, oksigen terlarut, nitrit, nitrat, dan total fosfat. Hasil penelitian secara spasial dan temporal pada enam stasiun pengamatan memiliki nilai bervariasi yang berkisar antara 0,93 hingga 6,45 yang mengindikasikan bahwa status perairan air tergolong dalam kondisi baik hingga tercemar sedang, sedangkan nilai CCME berkisar antara 33,53 hingga 63,90 yang mengindikasikan mutu perairan tergolong kurang baik hingga buruk.

The Kemayungan-Linduk coastal area is located in Banten Bay (Banten Province), which is a residential area that has high potential in various sectors including aquaculture and capture fisheries. Various anthropogenic activities and natural changes in environmental factors influence the entry of pollutant materials into the waters, resulting in changes in water quality conditions and biota around the waters. This research aims to determine water quality of coastal waters in the Kemayungan-Linduk region using two methods, namely calculating the Pollution Index (IP) and the CCME Index (Canadian Council of Ministers of the Environment) in the context of fisheries development. Water quality observations were carried out in-situ and ex-situ by taking water samples from February to April 2021 at six stations. The water quality parameters observed were temperature, transparency, turbidity, TSS, pH, salinity, dissolved oxygen, nitrite, nitrate and total phosphate. The results of spatial and temporal research at six observation stations have varying values ranging from 0,93 to 6,45 which indicates that the status of the water is classified as being in a good condition to moderately polluted condition, while the CCME value ranges from 33,53 to 63,90 which indicates Water quality is classified as marginal to poor.
