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

Tanggetada District has a large area of seagrass beds and is often used by the community. Seagrass beds in this area have not been scientifically confirmed, both in terms of species, density and seagrass communities. This study aims to determine the type and density of seagrass in Tanggetada District. The method used in this study is a quadratic transect method in an area of 100 m2 at each station. The location of the research was carried out at 3 stations, namely Station 1 in Tanggetada Village, Station 2 in Palewai Village and Station 3 in Anaiwoi Village. The results showed that 6 species of seagrass were found in Tanggetada District, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halodule uninervis, Halophila ovalis, and Syringodium isoetifolium. Seagrass density is included in the category of dense and rare. Station 1 has a high density of seagrass with a dense category of 160.46 ind/m2, then Station 2 with a rather dense seagrass density of 117.49 ind/m2 and Station 3 with a low density of seagrass with a rare category of 60.59 ind/m2. Thalassia Hempricii is a seagrass that has the highest density value compared to other seagrass speciesseagrass density in the rare category. Thalassia Hempricii is a seagrass that has the highest density value compared to other seagrass species.

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.
