Aulanniam, DES </p><p>Dibiayai oleh Direktorat Jendral Pendidikan Tinggi, Departemen Pendidikan Nasional, melalui DIPA Universitas Brawijaya </p><p>No 0174.0/02304.2/XV/2009 tanggal 31 Desember 2008, dan berdasarkan SK Rektor Nomor : 160/SK/2009, tanggal 7 Mei 2009 </p><p>UNIVERSTAS BRAWIJAYA </p><p>MALANG, NOVEMBER 2009 </p></li><li><p>RINGKASAN </p><p>Resiko polusi lingkungan ion logam berat Pb karena toxisitas serta menyebabkan </p><p>kelumpuhan dan akumulasi dalam biota, maka diperlukan monitoring konsentrasi logam </p><p>berat dalam lingkungan. Analisa kandungan logam berat dalam sedimen dan air banyak </p><p>dilakukan namun dalam tumbuhan lamun masih sangat sedikit dilakukan. Tujuan 1). </p><p>Mengetahui kandungan Pb pada akar, seludang dan daun lamun, sedimen dan air dari </p><p>lokasi yang berbeda 2). Menentukan tingkat pencemaran perairan pesisir Utara Jawa </p><p>Timur berdasarkan kandungan logam berat Pb; 3). Mengetahui dan menentukan profil </p><p>protein bagian - bagian tumbuhan lamun yang terkontaminasi Pb. Hasil penelitian didapat </p><p>1). Kandungan Pb dalam tumbuhan lamun dan sedimen di lingkungan tercemar </p><p>cenderung lebih tinggi daripada di lingkungan tidak tercemar; 2). Kandungan Pb air laut </p><p>Lamongan (0,062 0,003 ppm) dan Lempuyang (0,049 0,004 ppm) &lt; sedimen </p><p>Lamongan (5,847 0,058 ppm) dan Lempuyang (1,238 0,034 ppm) namun pada air </p><p>sudah melebihi ambang batas Baku mutu air laut untuk kehidupan biota oleh KMNLH </p><p>(2004) 0,008 ppm; 3). Profil protein menunjukkan terekspresi hampir sama dengan berat </p><p>molekul 75,7 kDa di Lamongan dan 72 kDa di Lempuyang dari sampel akar, seludang </p><p>dan daun lamun Cymodocea rotundata. Disarankan 1). Tumbuhan lamun berguna untuk </p><p>membantu mengurangi toksisitas Pb di perairan pesisir; 2). Perlu penelitian tentang luas </p><p>area tumbuhan lamun pada suatu perairan dalam upaya mengurangi kandungan Pb dan 3). </p><p>Perlu dilakukan pengamatan tentang pengaruh salinitas yang lebih rendah </p><p>Kata kunci : lamun dan logam berat Pb </p></li><li><p> SUMMARY </p><p>Environmental pollution risk Pb heavy metal ion because toxicitas and causes </p><p>immobility and accumulation in biota, therefore needful monitoring concentrates heavy </p><p>metal in environmentally. Heavy metal concentration analysis in sedimentary and water a </p><p>lot of is done but on seagrass still measly is done. To the effect 1). Knowing Pb content </p><p>on seagrass parts (root, rhizome and leaf ), sediment and water of location that variably </p><p>2). Determining pollution degree Javanese North coast East base Pb's heavy metal </p><p>content; 3 ). Know and determines seagrass part protein profiles contamination Pbs ones. </p><p>Observational result to be gotten 1). Pb's content in seagrass and sedimentary at begrimed </p><p>environment tends to overbid than at environment is not begrimed; 2 ). Pb's content water </p><p>goes out to sea Lamongan (0,062 0,003 ppm) and Lempuyang (0,049 0,004 ppm) &lt; </p><p>Lamongan's sediment (5,847 0,058 ppm) and Lempuyang (1,238 0,034 ppm) but on </p><p>water was overshot Default bounds sill water quality goes out to sea to biota's life by </p><p>KMNLH (2004) 0,008 ppm; 3 ). Protein profile points out most expression close </p><p>resemblance heavily molecule 75,7 kDa at Lamongan and 72 kDa at Lempuyang of root </p><p>sample, seludang and leaf romances Cymodocea rotundata . Suggested 1). Seagrass plant </p><p>to help reduce Pb's toxicity at coast waters; 2 ). Need research seagrass area extent at one </p><p>particular waters in the effort reduce Pb's content and 3).
