Abstract


The study of Pb content in suspended solid and dissolved in the waters of Belawan Port was conducted on September until October 2009. Analysis of Pb content in suspended solid was measured at Health Clinic Laboratory, North Sumatra and Pb dissolved analyzing was done at the Palembang Research and Industry Standaritation Laboratory in South Sumatra. Pb content in suspended solid at high tide ranged from <0.02 to 0.05 mg / l and at low tide ranged from 0.02 to 0.07 mg / l. The content of dissolved Pb at high tide ranged from 0.235 to 0.676 mg / l and at low tide ranged from 0.287 to 0.748 mg / l. Content of Pb in the waters of Belawan has passed quality standard of the Minister of Environment of Republic Indonesia that means the Harbour area is polluted and improper for drinking water as well as for fish cultivation.

 

Key words : Pb content, Suspended Solid, Water of Belawan Port

 

 

ABSTRAK

Penelitian kandungan logam berat Pb dalam Muatan Padatan Tersuspensi dan terlarut di Perairan Pelabuhan Belawan ini dilakukan pada bulan September sampai dengan Oktober 2009 pada saat pasang dan surut. Analisis dilakukan di Balai Laboratorium Kesehatan Provinsi Sumatera Utara dan di Laboratorium Balai Riset dan standardisasi Industri Palembang Provinsi Sumatera Selatan. Hasil kandungan logam berat Pb dalam Muatan Padatan Tersuspensi saat pasang berkisar antara < 0,02 – 0,05 mg/l dan saat surut berkisar antara 0,02 – 0,07 mg/l. Kandungan logam berat Pb terlarut saat pasang berkisar antara 0,235 – 0,676 mg/l dan saat surut berkisar antara 0,287 – 0,748 mg/l. Kandungan logam berat Pb di Perairan Pelabuhan Belawan sudah melewati batas baku mutu menurut Keputusan Menteri Negara Lingkungan Hidup Nomor 51 Tahun 2004 yaitu 0,05 mg/l yang berarti bahwa Perairan Pelabuhan Belawan sudah tercemar dan tidak layak dipergunakan untuk air baku air minum maupun untuk kegiatan pembudidayaan ikan.

 

Kata Kunci : Kandungan logam berat Pb, Muatan Padatan Tersuspensi, Perairan Pelabuhan Belawan
