CONCENTRATION OF HEAVY METALS ON ROOTS, STEM AND LEAVES OF Enhalus acoroides, IN TUNDA ISLAND, BANTEN BAY

Abstract: Heavy metal pollution is one of serious problem for tropical mangrove ecosystem. Heavy metals can decrease the quality of a waters. The decreasing in water quality can caused by pollutants such as heavy metals with high concentrations greatly affects the aquatic environment, especially living organisms. The aimed of study is to determine the accumulation level of heavy metals such as Al, Cu, Pb, As, Ni, Cr, Ti, Mn, dan Fe, in root, leaves and stem of E. acoroides. The sampling was carried out in the northern a… Show more

“…The chlorophyll content in seagrass leaves is determined using a UV-Vis spectrophotometer, and its value is obtained based on the calculation formula according to Granger and Izumi (2002) Clo a = 11,93(Abs 664) -1,93(Abs 647) ......................(3) Multivariate analysis of variance (MANOVA) is a statistical procedure that simultaneously assesses the impact of independent variables with categorical scales on multiple dependent variables with quantitative data scales. MANOVA tests whether significant differences exist between two levels of one variable in several concurrent variables (Zamani et al, 2018). Manova will analyze data to determine if liquid fertilizer concentration (independent variable) affects seagrass survival, growth, biomass, and chlorophyll-a (dependent variable).…”

“…Tinggi rendahnya nilai kadar air, susut pengeringan dan kadar abu dari tumbuhan lamun Enhalus acoroides dapat dipengaruhi oleh musim, sampel lamun Enhalus acoroides yang digunakan tersebut diambil pada bulan Desember, dimana pada musim dingin nilai nutrisi lamun lebih rendah dibandingkan dengan musim semi dan musim panas. Selain itu bioakumulasi logam berat dominan pada daun dan batang lamun, karena masuknya logam berat ke lamun, jaringan penyimpanan zat dan karakteristik lamun yang terendam sepenuhnya dalam air, sehingga dapat mempengaruhi besarnya penentuan kadar abu pada tanaman lamun, hal ini dapat dipengaruhi oleh habitat dan lingkungan perairan dimana lamun tersebut tumbuh yaitu dengan tingkat ketersediaan nutrisi serta musim (Zamani et al, 2018dan Rumiantin, 2011.…”

“…Lamun dapat menjadi bioindikator lingkungan karena lamun dapat menyerap dan mengakumulasikan logam berat di dalam organ tubuhnya. Jika kandungan logam berat diperairan meningkat maka akan mengancam ekosistem laut serta biota yang hidup didalamnya (Zamani et al, 2018). Sekotong merupakan salah satu daerah di Nusa Tenggara Barat dengan potensi tambangan emas yang besar, sehingga memiliki potensi terjadinya pencemaran lingkungan laut akibat aktivitas penambang emas liar.…”
