Abstract

One of seagrass dominant species found in Indonesia is Enhalus acoroides. This species can form single seagrass bed vegetation (monospecies vegetation) and mixed with others species (multispecies vegetation). Seagrass composition in coastal areas can be affected by surrounding associated species such as herbivorous fish and invertebrates. Human activities, especially in coastal communities, can negatively influence seagrass beds. Therefore, it is needed an effort to rehabilitate the affected seagrass. Transplantation technic is one effort for rehabilitation. The purposes of the research were to analyze growth rate, percent cover, and survival rates of seagrass E. acoroides transplanted as monospecies and multispecies. This research used a monospecies of E. acoroides and multispecies (2, 4, and 5 species) that combined to others species such as T. hemprichii, C. rotundata, H. ovalis, H. uninervis, and S. isoetifolium. Research results showed that the highest average growth rate of transplanted E. acoroides was found in monospecies treatment with 0.29 cm/day. The highest average cover changing was found on two combined species i.e., E. acoroides and C. rotundata, as high as 0.10% per day. The highest survival rates were found in 2 combined treatment i.e., E. acoroides and H. ovalis, and 5 combined species such as E. acoroides, S. isoetifolium, C. rotundata, H. uninervis dan H. ovalis with value 100 percent, respectively.

Abstract

One of the ecological functions of the seagrass ecosystem is the ability to absorb carbon coming from the atmosphere. The ability of seagrass to absorb carbon is carried out through photosynthesis. The absorbed carbon will then be stored in the form of seagrass biomass in the seagrass body. This study aims to estimate the carbon stock content stored in seagrass ecosystems in the Northern waters of Papua including on Liki Island, Befondi Island, and Meossu Island. The calculation of carbon stock is done by converting seagrass biomass using constants derived from representative values of seagrass carbon content in Indonesian waters. In general, based on the results obtained indicate that the biomass at the bellow ground of the seagrass is greater than the biomass at above ground the seagrass. The value of organic carbon content in seagrasses is influenced by seagrass biomass. The carbon stock content in the seagrass ecosystem in the study area is in the range of 18,04 – 419,46 g C / m2. Stations on Liki Island have generally higher carbon stocks compared to stations on other islands.Salah satu fungsi ekologi dari ekosistem lamun yaitu memiliki kemampuan dalam menyerap karbon yang berasal dari atmosfer. Kemampuan lamun dalam menyerap karbon dilakukan melalui proses fotosintesis. Karbon yang terserap selanjutnya akan disimpan dalam bentuk biomassa lamun  pada tubuh lamun. Penelitian ini bertujuan untuk mengestimasi kandungan stok karbon yang tersimpan pada ekosistem lamun di Perairan Utara Papua tepatnya di Pulau Liki, Pulau Befondi dan Pulau Meossu. Perhitungan stok karbon dilakukan dengan melakukan konversi biomassa lamun menggunakan konstanta yang berasal dari nilai representatif konsentrasi kandungan karbon pada lamun yang berada di Perairan Indonesia. Secara umum berdasarkan hasil yang diperoleh menunjukkan bahwa biomassa pada bagian bawah lamun lebih besar dibandingkan dengan biomassa pada bagian atas lamun. Nilai kandungan karbon organik pada lamun dipengaruhi oleh biomassa lamun. Kandungan stok karbon pada ekosistem lamun di wilayah penelitian  berada pada kisaran 18,04 – 419,46 gC/m2. Stasiun yang berada di Pulau Liki memiliki stok karbon yang umumnya lebih tinggi dibandingkan dengan stasiun yang berada di pulau lainnya.

Abstract

Hutan mangrove kini menghadapi ancaman serius, dimana tekanan antropogenik manusia telah meningkat pesat di wilayah pesisir sekitar kawasan mangrove. Kajian ekologi perairan Pulau Tunda Serang Banten khususnya keadaan umum hutan mangrovenya telah dilakukan pada bulan Januari 2014. Hal ini bertujuan sebagai data dasar dalam mengevaluasi pengelolaan mangrove di Indonesia (khususnya Pulau Tunda Serang Banten) dan kedepannya keberadaan hutan mangrove Indonesia dapat dipertahankan. Data kondisi vegetasi mangrove Pulau Tunda Serang Banten dikumpulkan dengan membuat transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan. Sementara pengukuran kualitas perairan dilakukan secara in-situ. Hasil penelitian menunjukan bahwa pertumbuhan hutan mangrove Pulau Tunda Serang Banten pada bagian Timur (Stasiun 1) lebih muda dibandingkan bagian Selatan (Stasiun 2). Kemudian kerapatannya juga lebih tinggi di bagian Timur daripada bagian Selatan, namun kondisi hutan mangrove kedua stasiun masih tergolong baik dan sangat padat. Selain itu, kualitas lingkungan vegetasi mangrove Pulau Tunda masih tergolong tinggi, keanekaragaman maupun dominansi hutan mangrovenya tergolong rendah, keseragaman dalam keadaan agak seimbang, pola penyebarannya tergolong beraturan (regular) dan parameter kualitas perairan tidak menjadi penghambat bagi pertumbuhan mangrovenya.

Abstract

Corals are one of the organisms that are sensitive to physical and chemical changes in the marine environment. Coral reefs in Pomalaa waters are starting to be threatened because of the nickel mining. This study aims to examine the water quality of coral reefs, and the level of accumulation of heavy metals (Pb, Cd, and Hg) in the waters and on coral (Acropora aspera) in Pomalaa waters. Samples were taken at 4 stations with the parameters measured were temperature, dissolved oxygen, pH, salinity, water clarity, current velocity, nitrate and phosphate. Seawater samples at each station were taken using a 500 ml sample bottle and 5 ml of HNO3 was added. Coral samples were taken at a depth of 5-10 m at 3-5 cm then prepared and analyzed using Atomic Absorption Spectrometer Method. The results showed that the heavy metals concentrations in water and coral had different concentrations. Accumulation of heavy metals in water samples exceeds the threshold for sea water quality standards for marine biota. Accumulation of heavy metals in coral skeletons has different concentrations for each type of metal. Concentration of Pb in corals ranged from 1.20 to 28.40 mg/kg. Concentrations Cd from 12.06 to 18.53 mg/kg, while the Hg concentration from 0.03 to 1.70 mg/kg. Concentration of metals accumulated in corals is greater than in seawater. Corals have a high tendency to accumulate metals, so they can be used as bioindicators to see the level of pollution in marine waters.

Abstract

Corals are unique and specific ecosystems found in tropical waters, and are vulnerable to changes in the aquatic environment. This study aims to determine the percentage of coral reef cover and coral reef mortality index in Pomalaa waters. Coral observations were carried out at a depth of 3 m to represent shallow waters and 7 m to represent deep waters, each of which consisted of 4 observation points. The water quality parameters that were measured directly in the field were temperature, salinity, pH, water brightness and current speed using a Water Quality Checker (TOAA) and for nitrate and phosphate analysis carried out in the laboratory. The results showed that the water quality at each research station did not differ that much. The condition of coral reefs in Pomalaa waters at a depth of 3 m is categorized as damaged, with the percentage of live coral cover ranging from 11.85% - 22.07%. At a depth of 7 m the average is in moderate to damaged condition, with the percentage of cover in the range of 16.13% - 28.81%. This shows that coral diversity is generally low, so that no coral species dominates. The mortality rate of coral reefs in Pomalaa waters is high at a depth of 3 meters, namely 0.75, meaning that 75% of coral reefs are in bad condition to death, as well as at a depth of 7 meters, the highest mortality index is 0.63 meaning 63% of coral reefs in a depth of 7 meters experienced bad conditions to death.

Abstract

Microplastic pollution is a threat to marine ecosystems. Microplatics in coral reef ecosystems can pose a threat to coral reef health. This study aims to determine the  condition of coral reefs, and  the distribution of microplastics in the tourist area of Bokori island as a first step for conservation and mitigation from the impact of microplastic pollution.  Sampling wa carried out at 4 research stations. The environmental quality parameters measured were temperatur, dissolved oxygen, pH, salinity, water brightness, current, nitrate, and phosphate. Sampling using purposive sampling method. Sediment sampling using Scuba set and sediment grab at a depth of 3-10 meters. Sediment is taken ±1000 gr and stored in double zip lock plastic. The samples were the analyzed and observed using microplastics laboratory. The results showed that there are four types of microplastics found in sediments in the waters of the island of Bokori, namely fiber, foam, film, and fragments. Fiber is the most common type of microplastic with an average of 41.564 particles/kg dry sediment per aobservation station, while the lowest abundance was foam type with an average value of 9.379 particles/kg dry sediment. The abundance of microplastic at each sampling location was not the same due to the different characteristics of the study sites.
