Abstract
Merkuri adalah logam berat yang bersifat toksik dan dapat terdeposit ke dalam air serta sedimen, teroksidasi ke udara, dan berakhir di lautan. Merkuri juga dapat terbioakumulasi pada jaringan makhluk hidup, seperti lamun Cymodocea rotundata. Kemampuan C. rotundata dalam akumulasi merkuri belum diketahui. Tujuan penelitian ini adalah untuk memperoleh informasi terkait perbandingan kadar merkuri antara C. rotundata dan sedimen pada P. Rambut dan P. Untung Jawa dan mengetahui kemampuan bioakumulasi merkuri pada C. rotundata. Sampel C. rotundata dan sedimen diambil dari P. Rambut dan P. Untung Jawa yang kemungkinan terdampak pencemaran merkuri dari Teluk Jakarta. Metode yang digunakan adalah metode deskriptif, dengan teknik purposive sampling. Kadar merkuri pada sampel dianalisis dengan ICP-MS di PT. SIG. Data kadar merkuri kemudian dianalisis secara statistik dengan uji two-way ANOVA. Hasil menunjukkan sampel dengan kadar merkuri terbesar yaitu sedimen pada P. Rambut dan adanya batasan pada organ C. rotundata dalam penyerapan Hg. Nilai BAF C. rotundata di P. Rambut (0,91) dan di P. Untung Jawa (0,96) menunjukkan C. rotundata dapat menjadi bioindikator merkuri meskipun bukan bioakumulator. ***************************************** Mercury is a toxic heavy metal and can be deposited in water and sediments, oxidized into the air, and ends up in the oceans. Mercury can also bioaccumulate into the tissues of organism, such as the seagrass Cymodocea rotundata. The ability of C. rotundata in mercury accumulation is not known. The purpose of this study was to obtain information related to the comparison of mercury content between C. rotundata and sediments in P. Rambut and P. Untung Jawa and to determine the bioaccumulation ability of mercury in C. rotundata. Samples of C. rotundata and sediment were taken from P. Rambut and P. Untung Jawa which may be affected by mercury pollution from Jakarta Bay. The method used is descriptive method, with purposive sampling technique. Mercury content in the samples were analyzed by ICP-MS at PT. SIG. The mercury content data were then statistically analyzed using a two-way ANOVA test. The results showed that the sample with the highest mercury content was sediment in P. Rambut and there was a limitation in the C. rotundata organ in Hg absorption. The BAF value of C. rotundata in P. Rambut (0,91) and P. Untung Jawa (0,96) indicated that C. rotundata could be used as mercury bioindicator even though it was not a bioaccumulator.
