“…The cuticle serves to absorb nutrients, although in lesser amounts than those absorbed by the roots (Tomasick et al, 1997). The concentration of heavy metals found in water and substrate does not affect the size of the concentration of heavy metals in parts of seagrass plants (Nugraha et al, 2017). Although the most dominant heavy metals in sediments and seawater are aluminum, this does not affect the size or concentration of heavy metals in seagrass.…”

“…The presence of bioaccumulation of heavy metals in the stem can also occur because in the part of the seagrass stem there is a cortical network consisting of colenchymal and parenchymal tissue. These networks function as the basic network for filling and storing substances such as heavy metals (Nugraha et al, 2017). In addition, according to , the location of seagrass submerged entirely in water can affect the bioaccumulation location of heavy metals in plant structures.…”

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 and southern parts of Tunda Island, in March 2015. The method used for seagrass destruction is 6 mL 65% HNO3 and mL H2O2 30%, sediment destruction using Milestone Start D microwave labstation. and using ICP-OES (Inductive Coupled Plasma-Optical Emission Spectrometry) Thermo Scientific iCAP 700 Series. The result show that, the Al, was the dominant heavy metals observed both in sea water and sediment surrounding the observed sea grass areas. Similar result was also observed for seagrass. The dominant sediment grain size absorbing heavy metals is silt-clay because it has more organic matter to control the binding of heavy metals. Heavy metal bioaccumulation is predominant in seagrass leaves and stems due to heavy metal entry into seagrass, substance storage tissue, and seagrass characteristics that are completely submerged in water. Seagrass meadow ecosystem in Tunda Island has been contaminated by several heavy metals. ABSTRAKPencemaran logam berat adalah salah satu masalah serius bagi ekosistem bakau tropis. Logam berat dapat menurunkan kualitas perairan. Penurunan kualitas perairan yang diakibatkan oleh zat pencemaran seperti logam berat dengan konsentrasi yang sangat tinggi mempengaruhi lingkungan akuatik, terutama organisme hidup. Tujuan penelitian adalah untuk menentukan tingkat akumulasi logam berat seperti Al, Cu, Pb, As, Ni, Cr, Ti, Mn, dan Fe, di akar, daun dan batang E. acoroides. Pengambilan sampel dilakukan di bagian utara dan selatan Pulau Tunda Banten pada Maret 2015. Metode yang digunakan untuk destruksi lamun yaitu 6 mL HNO3 65% dan mL H2O2 30%, destruksi sedimen menggunakan Milestone Start D microwave labstation, dan ICP-OES (Inductive Coupled Plasma-Optical Emission Spectrometry). Hasil menunjukkan bahwa, Al adalah logam berat dominan yang diamati baik di air laut maupun sedimen di sekitar rumput laut. Hasil serupa juga ditemukan untuk lamun. Ukuran butiran sedimen dominan yang menyerap logam berat adalah lanau lempung karena memiliki lebih banyak bahan organik untuk mengontrol pengikatan logam berat. 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. Ekosistem padang lamun di Pulau Tunda telah terkontaminasi oleh beberapa logam berat yang melewati tingkat tercemar.

“…Berdasarkan hasil penelitian yang telah dilakukan selama selama 30 hari, pertumbuhan ratarata lamun T. hemprichii di Perairan Pengudang yaitu 1.03 mm/hari, sedangkan rata-rata pertumbuhan lamun T. hemprichii di Perairan Dompak yaitu 0.77 mm/hari. Sebagaimana telah dilakukan penelitian oleh Nugraha et al (2017), laju pertumbuhan daun lamun jenis T. hemprichii rata-rata 4.16 mm/hari di Pulau Pari, Kepulauan Seribu, DKI Jakarta. Jika dibandingkan dengan Penelitian Nugraha et al (2017), maka laju pertumbuhan daun lamun jenis T. hemprichii di Perairan Pengudang dan Dompak tergolong sangat rendah.…”

Research on the rate of growth and reproduction of seagrass leaf type Thalassia hemprichii has been done in the waters of Pengudang and Dompak, Bintan Island. Aim this research for compare the growth rate and the production rate of Thalassia hemprichii biomass in Pengudang and Dompak coastal area, Bintan Island. The research was done by purposive sampling method, 30 individu seagrass leaves samples were taken using a plot measuring 50x50 centimeters. The results of the study were in the growth rate of the seagrass leaf type Thalassia hemprichii in the waters of Pengudang and Dompak 1.03 mm/day and 0.77 mm/day. Production rate of the Thalassia hemprichii leave biomass 0.07 gDW/m2 at Pengudang and 0.03 gDW/m2 at Dompak. Density of seagrass type Thalassia hemprichii 119.22 stands/m2 at Pengudang and 96.00 stands/m2 at Dompak. Based on test Two-Way ANOVA. There is no noticeable difference between the growth and production of the type of seagrass leaves Thalassia hemprichii in the waters of Pengudang and Dompak, Bintan Island.

“…The total highest seagrass percent cover was found at station 3 which located in the western of Liki Island. Anthropogenic is one of the factor which influence the physiological response of seagrass (;Nugraha et al;2017). The condition of seagrass beds in Liki Island that has small population and a location very far from the main land, causes condition of the environment that still maintained and has a little impact on the high seagrass persent cover.…”

Dugong dugon is a herbivorous marine mammal. One of Dugong's favorite foods is seagrass. This study examines the distribution of seagrass species to dugong sighting in Liki Island. The study was conducted in November 2018. Observation of seagrass conditions was carried out using a line transect method and a 50x50 cm transect with a distance interval between 10 m plots. Interviews were also conducted with the community to find out the location of Dugong presence in Liki Island. There are seven species of seagrass found in Liki Island :Enhalus acoroides, Cymodocea rotundata, Thalassia hemprichii, Halophila ovalis, Halodule uninervis, Halodule pnifolia and Syringodium isoetifolium spread over four observation stations. The results showed that Dugong in Liki Island is often found during the eastern season, they often appear in seagrass ecosystem area to do eating activities. Dugong is often found in the eastern part of Liki Island (Station 4) and sometimes also found in the western part of Liki Island (Station 3).Keywords:biodiversity,Dugong dugon, liki, papua, seagrass
