Abstract
Muara Sungai Mrican di Perairan Pekalongan dimanfaatkan untuk pemukiman, budidaya ikan, dan industri sehingga berpotensi menghasilkan limbah organik dan mempengaruhi konsentrasi klorofil-a sebagai indikator kesuburan perairan. Penelitian ini bertujuan untuk mengidentifikasi konsentrasi dan sebaran klorofil-a serta menganalisis korelasinya dengan suhu, salinitas, pH, DO. Metode yang digunakan pada menelitian ini adalah metode kuantitatif dengan pengambilan sampel air dan data parameter kualitas perairan secara in situ di 28 titik lokasi pada 30 Mei 2024 pukul 07.00 – 12.00 WIB.. Korelasi klorofil-a dengan suhu, salinitas, pH, dan DO dianalisis menggunakan korelasi Pearson. Berdasarkan hasil penelitian yang lakukan, konsentrasi klorofil-a menunjukkan kisaran antara 2.6329 – 30.5967 mg/L. Konsentrasi klorofil-a tersebut berkaitan erat dengan suplai nutrien, hasil degradasi limbah organik pada perairan Mrican. Konsentrasi klorofil-a menunjukkan nilai yang tinggi di wilayah muara dan menurun saat menjauh dari pantai. Klorofil-a memiliki korelasi positif dengan suhu, serta berkorelasi negatif dengan salinitas, pH, dan DO, yaitu perairan dengan salinitas, pH, dan DO.
