ABSTRAK
Penelitian ini bertujuan untuk mengetahui kondisi kualiats air dan jenis fraksi sedimen pada kawasan mangrove di seputaran Aceh Utara ditinjau dari parameter fisika dan kimia. Penelitian ini meliputi 3 titik penelitian dengan 12 parameter kimia dan fisika dengan jarak kedalaman tiap pengambilan sampel 1-2,3 m. Dilakukan pula pengukuran pada sedimen terhadap kandungan logam berat. Penguajian melalui 2 tahapan uji yaitu uji insitu diantaranya suhu, kecerahan, salinitas, DO, pH. Sedangkan uji eksitu diantaranya TSS, timbal (Pb) termbaga (Cu), cadmium (Cd), besi (Fe), mercury (Hg) dan amonia (NH3). Berdasarkan Hasil penelitian diperoleh hasil suhu 27-28,8 0C; pH 6,8-7,7; salinitas 1,51-1,72 mg/l; kecerahan 1,5-1,9 m; DO 4,9-5,7 mg/l; TSS 7,9-10,3 mg/l; timbal 0,003 mg/l; Tembaga (Cu) 0,022- 0,025 mg/l; cadmium 0,001-0,010 mg/l; besi (Fe) 0,003-0,625 mg/l; mercury (Hg) 0,001 mg/l; amonia (NH3) 0,21-0,33 mg/l. Kandungan logam berat pada sedimen timbal (Pb) 0,010-0,016 mg/l; Teambaga (Cu) 0,023-0,029 mg/l; cadmium (Cd) 0,012-0,023 mg/l; mercury (Hg) 1,898-2,509 mg/l; amonia (NH3 ) 0,003-0,060. Baku mutu untuk wisata bahari kawasan mangrove daerah Aceh Utara adalah sesuai dengan baku mutu (Standar kualitas) Lingkungan Hidup Nomor 115 Tahun 2003.

ABSTRACT This reaserch conducted to understand the quality of water and the type of sediment fraction in the mangrove area around North Aceh in terms of physical and chemical parameters. This research includes 3 research points with 12 chemical and physical parameters with a depth of 1-2,3 m for each sampling. Measurements were also made on the sediment for heavy metal content. The test went through 2 test stages, namely in situ test including temperature, brightness, salinity, DO, pH. While the ex-situ tests include TSS, lead (Pb), copper (Cu), cadmium (Cd), iron (Fe), mercury (Hg) and ammonia (NH3). Based on the results of the study, the temperature results were 27-28.8 0C; pH 6.8-7.7; salinity 1.51-1.72 mg/l; brightness 1.5-1.9 m; DO 4.9-5.7 mg/l; TSS 7.9-10.3 mg/l; lead 0.003 mg/l; Copper (Cu) 0.022- 0.025 mg/l; cadmium 0.001-0.010 mg/l; iron (Fe) 0.003-0.625 mg/l; mercury (Hg) 0.001 mg/l; ammonia (NH3) 0.21-0.33 mg/l. Heavy metal content in lead sediment (Pb) 0.010-0.016 mg/l; Teambaga (Cu) 0.023-0.029 mg/l; cadmium (Cd) 0.012-0.023 mg/l; mercury (Hg) 1.898-2.509 mg/l; ammonia (NH3 ) 0.003-0.060. The quality standard for marine tourism in the mangrove area of North Aceh is in accordance with the Environmental Quality Standards Number 115 of 2003.
