“…The hard coral in this region also infected by various coral diseases, e.g., black band disease, white syndrome, skeleton eroding band, and yellow band disease (Johan et al, 2015). Offshore mining activity increased community wealth, but on the other side, the activity changes environmental stability (Nurtjahya et al, 2017). After the mining activity is done, the location will experience heavy organic water pollution (Liliani et al, 2019).…”

Bangka Belitung Islands (Sumatra, Indonesia) has various coastal resources, e.g., coral reefs, seagrass beds, mangrove forests. However, the coral community has been threatened by anthropogenic activities, i.e., tin mining and illegal tin mining. Threatened species assessment is important for mitigation of coral losses and management. The ojective of the present study was to examine the status of Scleractinian corals in Bangka Belitung Islands, Indonesia. A line intercept transect was performed for the coral reef survey. Live and dead coral cover were recorded in the three locations. Corals species were identified following taxonomic revisions. The results showed that there were 142 species of Scleractinian corals recorded from Bangka Belitung Islands. Of these, 22 species are the new report from the areas of the the eastern part of Belitung Island. Family of Merulinidae, Acroporidae, and Poritidae were predominant group in this region. It is concluded that the condition of the coral reef ecosystem in the Belitung Islands is relatively good, but fair in Gaspar Strait and Bangka Island.

“…Sebaran lamun di Kepulauan Bangka Belitung yang telah di laporkan ditemukan di Bangka Tengah, Bangka Selatan dan Belitung Timur (Prabowo et al, 2010;Adi, 2015;Akhrianti et al, 2014) Kondisi padang lamun di Kepulauan Bangka Belitung, khususnya di Bangka Selatan mengalami tekanan akibat dari aktivitas manusia seperti pembangunan dermaga, aktifitas nelayan dan kegiatan pertambangan timah di Laut (TI apung). TI apung dapat menyebabkan sedimentasi, kekeruhan perairan dan meningkatnya kandungan logam berat yang kemudian berdampak pada ekosistem padang lamun (Wahyuni et al, 2013;Nurtjahya et al, 2017;Sari et al, 2017). Menurunnya ekosistem padang lamun akan berdampak menurunya peran lamun sebagai jasa ekosistem di perairan (Christianen et al, 2013;Wahyudin et al, 2016;Scott et al, 2018).…”

South Bangka has a high potential for seagrass diversity, but information relating to the distribution of species and the condition of seagrass communities is still not widely understood. The research objective was to determine the number of species, distribution and conditions of seagrass communities in South Bangka. The research was conducted in June 2016 until May 2017. The location of the research was carried out in several areas of South Bangka, Bangka Belitung Islands. The distribution and number of seagrass species was determined based on a combination of primary data and secondary data. Data collection of seagrass condition includes seagrass coverage and density carried out using quadratic transect measuring 50 cm x 50 cm. The results of research in South Bangka found 10 species of seagrass. Seagrass distribution includes Tanjung Kerasak Beach (9 species), Lepar Island (8 species), Coastal Tukak Village (8 species), Anak Air Island (5 species), Puding Beach and Kelapan Island found only 4 species. Seagrass conditions in South Bangka with a density of 633.37 stands/m 2 to 1066.76 stands/m 2 . The average percentage of seagrass cover is 29.61% which is categorized as poor. ABSTRAKBangka Selatan memiliki potensi keanekaragaman lamun yang tinggi, tetapi informasi yang berkaitan dengan sebaran spesies dan kondisi komunitas lamun masih belum banyak diketahui. Tujuan penelitian yaitu menentukan jumlah spesies, sebaran dan kondisi komunitas lamun di Bangka Selatan. Penelitian dilaksanakan pada bulan Juni 2016 sampai Mei 2017. Lokasi penelitian dilakukan di beberapa wilayah Bangka Selatan, Kepulauan Bangka Belitung. Sebaran dan jumlah spesies lamun ditentukan berdasarkan gabungan data primer dan data sekunder. Pengambilan data kondisi padang lamun meliputi data tutupan dan kerapatan lamun dilakukan menggunakan transek kuadrat berukuran 50 cm x 50 cm. Hasil penelitian di Bangka Selatan ditemukan sebanyak 10 spesies lamun. Sebaran lamun meliputi Pantai Tanjung Kerasak (9 spesies), Pulau Lepar (8 spesies), Pesisir Desa Tukak (8 spesies), Pulau Anak Air (5 spesies), Pantai Puding dan Pulau Kelapan ditemukan hanya 4 spesies. Kondisi padang lamun di Bangka Selatan dengan kerapatan yaitu 633,37 tegakan/m 2 sampai 1066,76 tegakan/m 2 . Rata-rata persentase tutupan lamun yaitu 29,61% dikategorikan miskin.

Characteristic of Dog Conch (Strombus turturella) Habitat on The Seagrass Ecosystem Strombus turturella or commonly known as dog conch is one of marine shellfish which has important ecological role, as well as high economical value as fisheries commodity. The objectives of the study were to determine the density and biomass of the shellfish, as well as to observe the distribution pattern and the characteristics of dog conch habitat in the seagrass ecosystem. The research was conducted at Tukak Island and Anak Air Island, Bangka Belitung Islands. Density of the shellfish, seagrass coverage, seagrass density as well as water chemistry and physical parameters, while data collection in laboratory, measurement of dog conch biomass, substrate texture test and organic matter content. Habitat characteristics were determined using principal component analysis (PCA), which connects between dog conch density variables, seagrass vegetation and chemical physics parameters. The average density of dog conch in all locations is 2312 ind / ha. The pattern of distribution of dog conch at the study site there is a pattern of uniform distribution and clumping, but the overall pattern of distribution is clustering. The PCA results show dog conch, with habitat characteristics that is very low seagrass cover (1-5%), overgrown species of Halophila minor seagrass, with the condition of muddy sand substrate and low content of organic matter. Result of the correlation matrix dog conch was correlated with H. Minor seagrass (0.88), very low seagrass cover (0.86) and muddy sand substrate (0.9). This is aimed at dog conch keeping specific microhabitat in the seagrass ecosystem. Siput gonggong memiliki peranan ekologis yang penting di habitatnya. Nilai ekonomis siput gonggong yang tinggi sebagai komoditas perikanan telah menyebabkan eksploitasi berlebihan terhadap spesies tersebut. Tujuan penelitian yaitu 1)menentukan kepadatan dan biomassa siput gonggong, 2)Pola sebaran dan 3)Karakteristik habitat siput gonggong di ekosistem padang lamun. Penelitian dilakukan di Pesisir Tukak dan Pulau Anak Air, Kepulauaan Bangka Belitung. Pengambilan data di lapangan melputi pengukuran kepadatan, perhitungan tutupan lamun, kerapatan lamun dan pengukuran parameter fisika kimia perairan, sedangkan pengambilan data di laboratorium meiputi, pengukuran biomassa siput gonggong, uji tekstur substrat dan kandungan bahan organik. Karakteristik habitat ditentukan menggunakan analisis komponen utama (PCA), yang menghubungkan antar variabel kepadatan siput gonggong, vegetasi lamun dan parameter fisika kimia perairan. Kepadatan rata-rata siput gonggong di semua stasiun yaitu 2312 ind/ha. Pola sebaran siput gonggong di stasiun penelitian ada pola sebaran seragam dan mengelompok, tetapi secara keseluruhan pola sebaran yaitu mengelompok. Hasil PCA menujukan siput gonggong, dengan karakteristik habitat yaitu tutupan lamun sangat rendah (1-5 %), ditumbuhi spesies lamun Halophila minor, dengan kondisi substrat pasir berlumpur dan rendah kandungan bahan organik. Selain itu berdasarkan hasil matrik korelasi bagian dari output PCA siput gonggong berkorelasi positif dengan lamun H. Minor (0,88), tutupan lamun sangat rendah (0,86) dan substrat pasir berlumpur (0,9). Hal ini menujukan siput gonggong menepati mikrohabitat yang spesifik di ekosistem padang lamun.
