ABSTRAK Penelitian ini bertujuan untuk menganalisis kuantitas kandungan logam berat jenis timbal (Pb), kadmium (Cd), besi (Fe), merkuri (Hg), dan minyak solar di estuaria Krueng Cangkoi. Pengambilan sampel dilakukan di Krueng Cangkoi, Desa Padang Seurahet, Kecamatan Meureubo, Meulaboh, Aceh Barat. Analisa data dan proses penelitian dilaksanakan di Laboratorium Badan Riset dan Standardisasi Industri Daerah (BARISTAND) Kota Banda Aceh pada bulan Desember 2014 sampai dengan Januari 2015. Penelitian menggunakan metode purposive sampling dan data diperoleh berdasarkan uji Spektrofotometri Serapan Atom terhadap kandungan logam berat jenis Pb, Cd, Fe, Hg, dan minyak solar di 5 (lima) titik sampel. Hasil kuantitas Pb di stasiun I, II, III, IV, dan V masing-masing sebesar ND, ND, ND, 0,41, dan 0,96 mg/L. Kuantitas Cd di stasiun I, II, III, IV, dan V masing-masing sebesar 0,093, 0,14, 0,016, 0,0032, dan 0,027 mg/L. Kuantitas Fe di stasiun I, II, III, IV, dan V masing-masing sebesar 0,40, 0,18, 0,43, 0,23, dan 0,56 mg/L. Kuantitas Hg di stasiun I, II, III, IV, dan V masing-masing sebesar 0,000014 mg/L, 0,00011 mg/L, ND, ND, dan ND. Kuantitas minyak solar di stasiun I, II, III, IV, dan V keseluruhan yaitu ND. Tingkat kandungan logam berat Cd (0,14 mg/L) dan Fe (0,56 mg/L) di Krueng Cangkoi telah melampaui ambang batas baku mutu berdasarkan Peraturan Pemerintah No: 82/2001 yaitu 0,01 mg/L pada Cd dan 0,3 mg/L pada Fe. Hasil indeks pencemaran di Krueng Cangkoi didapatkan nilai indeks pencemaran Fe yaitu 1,76 mg/L tergolong cemar ringan dan nilai indeks pencemaran Cd yaitu 3,91 mg/L tergolong cemar sedang berdasarkan baku mutu KeMenLH No: 115/2003. *) ND: Not Detected Kata kunci : Krueng Cangkoi, logam berat, minyak solar, SSA, indeks pencemaran. iii ABSTRACT The objective of research to analyzed quantity of heavy metals types of: lead (Pb), cadmium (Cd), iron (Fe), mercury (Hg) and diesel fuel in estuaries of Krueng Cangkoi. Sampling was conducted on December 2014 until January 2015 in estuaries Krueng Cangkoi, Padang Seurahet Village, Meureubo Subdistrict, Meulaboh, West Aceh. The data analyzed and research process at the Laboratory Research and Standardization Industry (BARISTAND) Banda Aceh. The research used purposive sampling method and the data was obtained by Atomic Absorption Spectrophotometry method test for heavy metal content types of: Pb, Cd, Fe, Hg and diesel fuel at 5 (five) sites sampling. The results of Pb quantity in station I, II, III, IV, and V respectively ND, ND, ND, 0,41, and 0,96 mg/L. The Cd quantity in station I, II, III, IV, and V respectively 0,093, 0,14, 0,016, 0,0032, and 0,027 mg/L. The Fe quantity in station I, II, III, IV, and V respectively 0,40, 0,18, 0,43, 0,23, and 0,56 mg/L. The Hg quantity in station I, II, III, IV, and V respectively 0,000014 mg/L, 0,00011 mg/L, ND, ND, and ND. The diesel fuel quantity in station I, II, III, IV, and V totally were ND. Level of heavy metals Cd (0,14 mg/L) and Fe (0,56 mg/L) in Krueng Cangkoi has exceeded the quality standard threshold base on Government Regulation No: 82/2001 was 0,01 mg/L in Cd and 0,3 mg/L in Fe. The results of pollution index in Krueng Cangkoi obtained pollution index values of Fe was 1,76 mg/L classified of lightly-polluted and pollution index values of Cd was 3,91 mg/L classified of moderately-polluted based on quality standard of KemenLH No: 115/2003. *) ND: Not Detected Keywords: Krueng Cangkoi, heavy metal, diesel fuel, AAS, pollution index. 0 ELECTRONIC THESES AND DISSERTATION Universitas Syiah Kuala 17330 2015-10-21 22:57:46 2015-10-22 09:10:07 machine generated
