Abstract

Abstrak Teluk Ujung Batu terletak di Kecamatan Jepara, dan lokasinya sangat strategis karena berdekatan dengan Pelabuhan Kartini serta merupakan daerah perkotaan yang padat penduduk. Aktivitas masyarakat di daratan serta lalu lintas kapal di pelabuhan dapat menyebabkan timbulnya pencemaran laut yang berasal dari buangan limbah industri dan limbah kapal berupa pencemaran logam berat, serta dapat meningkatkan konsentrasi sebaran polutan padatantersuspensi yang dipengaruhi oleh pola arus di perairan setempat. Penelitian ini bertujuan untuk mengetahui pola sebaran padatantersuspensi dan unsur logam berat di perairan Teluk Ujung Batu, Jepara. Penelitian ini dilaksanakan pada tanggal 9–20 Februari 2014. Materi yang digunakan berupa sampel air laut, serta parameter pendukung berupa arus laut dan kualitas perairan. Metode yang digunakan dalam penelitian adalah metode deskriptif dan penentuan titik sampling menggunakan purposive sampling method. Analisis data untuk sebaran padatantersuspensi, kekeruhan, dan logam berat Cd, Pb, dan Zn menggunakan ArcGIS 10.1 dan untuk pola arus menggunakan model ADCIRC. Berdasarkan hasil penelitian diperoleh bahwa nilai konsentrasi padatantersuspensi tertinggi terdapat di muara sungai dengan nilai 21 mg/l dan nilai kekeruhan dengan nilai 51,9 mg/l. Sedangkan hasil tertinggi konsentrasi logam berat kadmium (Cd) dengan nilai 0,066 mg/l, timbal (Pb) dengan nilai 0,520 mg/l dan seng (Zn) dengan nilai 0,37 mg/l. Berdasarkan hasil yang didapat, bahwa pola sebaran padatantersuspensi menumpuk di daerah muara sungai karena terbawa arus yang bergerak pada saat surut yaitu dari daratan dan semakin berkurang saat menuju laut karena pergerakan arus yang menyebar. Hal ini sesuai dengan sumber padatantersuspensi yang berasal dari aliran sungai serta material darat. Sedangkan pola sebaran logam berat cenderung menyebar di perairan lepas namun masih berdekatan dengan daratan. Hal ini didukung dari sumber logam berat yang  berasal dari limbah industri di darat yang dibuang ke laut serta dari bahan bakar minyak kapal yang melewati daerah tersebut.
