Abstract

Taxonomically, according to the World Register of Marine Species (WORMS), in 2021 the naming of the species Cymodocea serrulata will change to Oceana serrulata (R. Brown) Byng & Christenh. Many studies have been carried out in the Province of the Bangka Belitung Islands, but this type of distribution map has not been presented in detail. Observation of seagrass in the field allows the identification of seagrasses with other types of seagrass. This study aimed to identify morphology, species distribution, and other types of seagrass often associated with seagrass species Oceana serrulata in the Province of the Bangka Belitung Islands. The methods in this study include data collection, identification, and map making. Morphological identification of seagrass species refers to several identification sources. The distribution map of Oceana serrulata is presented from the seagrass data collection that has been carried out. This research uses data from different times, the first was obtained from 2011 and 2022 as primary data. The results of the study explain the identification carried out on the Oceana serrulata has the same characteristics as identification literature. Similarities seen from the identification of leaf morphology which ribbon curved like, parallel leaf veins and triangular shaped sheaths. Other seagrass species that are most often associated with Oceana serrulata are Halodule uninervis and Enhalus acoroides. The map of the distribution of seagrass species Oceana serrulata is found on the islands of Bangka, Belitung, Anak Air, Lepar, Ketawai, Semujur, Kalimambang, Kelayang, Kepayang, Ruk, and Sebongkok islands.

Abstract

This study aimed to analyze the community structure of reef fish in the small island waters of Central Bangka. The research was conducted in March 2022 in the waters of Bebuar Island, Ketugar Island, Ketawai Island, and Gusung Asam Central Bangka Regency, Bangka Belitung Islands Province. The coral reef survey method uses purposive sampling and the coral reef fish visual census with data analysis of abundance, diversity index, uniformity, and dominance. In-site water quality measurements included six parameters: temperature, salinity, current, brightness, depth, and pH. The results showed that coral reef cover from 44.60 - 87.00% with the medium to very good category. The abundance of reef fish from 1 to 3 individuals/m2 was dominated by 18 species of the Pomacentridae family. The reef fish diversity index ranged from 2.47 to 2.90, including the medium category. The uniformity index value ranged from 0.79 - 0.94, including the high category, indicating that the species found were evenly distributed across all stations. The dominance index value ranges from 0.07 to 0.15, including low, where no species dominates significantly and the fish are evenly distributed. Temperature, brightness, pH, and salinity are factors that support the growth of coral and reef fish. A water current speed of 0.05 – 0.20 m/s is quite helpful in cleaning coral reefs from mud and can supply oxygen. Water conditions were categorized as good and fulfilled the seawater quality standards.

Abstract

Seagrass is a higher-level plant that has symbiosis, vessels and reproduces generatively and lives submerged in water. Seagrass has many functions in waters, namely as a breeding ground, primary producer, water stabilizer, and as a sediment trap. The large number of mining activities in the Bangka Belitung Islands Province, especially in South Bangka district, can cause sediment to enter the seagrass ecosystem which will indirectly damage the seagrass ecosystem. Not only mining, many other human activities around the seagrass ecosystem also pose a threat to this ecosystem, such as ship propellers, reclamation activities and dock construction. The method used to determine station points ispurposive sampling, to assess the condition of seagrass using the quadratic transect method at 3 stations, namely Penutuk, Tanjung Sangkar and Tanjung Labu. The research results of the seagrass area on Lepar Island in 2020 was 1437.53 Ha, in 2021 it was 1428.14 Ha, in 2022 it was 1339.54, and in 2023 it was 1258.22. The changes in seagrass area that occurred were a reduction in area of 9.39 Ha from 2020-2021, in 2021-2022 it decreased by 88.6, in 2022-2023 it decreased by 81.22 Ha and the total change in seagrass area from 2020-2023 was reduced by 179.31 Ha. The condition of seagrass cover on Lepar Island is categorized as poor with a percentage of station 1 (Penutuk) 22.042%, station 2 (Tanjung Sangkar) 14.071%, and Station 3 (Tanjung Labu) 0.0868%.

Abstract

Penelitian ini bertujuan untuk menganalisis potensi keberlanjutan kawasan konservasi ikan endemik Tempalak Mirah (Betta burdigala) pasca penetapannya sebagai Kekayaan Intelektual Komunal (KIK) di Kabupaten Bangka Selatan. Evaluasi menggunakan pendekatan Rapfish pada lima dimensi yaitu, ekologi, sosial, ekonomi, kelembagaan, dan kebijakan. Hasilnya menunjukkan seluruh dimensi berada pada kategori cukup berkelanjutan dengan nilai 59,55–69,84. Hasil Monte Carlo memiliki selisih kecil (1,07–2,22) yang menunjukkan bahwa model stabil dan tidak sensitif terhadap kesalahan acak. Nilai R² tinggi (0,9735–0,9747) memperkuat reliabilitas pemetaan MDS dan stress rendah (0,116–0,118) mengonfirmasi kualitas konfigurasi MDS. Analisis leverage menunjukkan sejumlah atribut sensitif dan berpengaruh terhadap peningkatan status keberlanjutan kawasan konservasi Tempalak Mirah. Nilai rata-rata leverage menunjukkan seluruh aspek memerlukan prioritas pembenahan agar pengelolaan kasawan konservasi tetap adaptif pasca penetapan sebagai KIK. Secara keseluruhan, kawasan konservasi Tempalak Mirah memiliki potensi keberlanjutan yang cukup, namun masih memerlukan dukungan regulasi, kelembagaan, serta pengelolaan ekologi dan sosial yang lebih terintegrasi demi memastikan perlindungan plasma nutfah endemik Bangka Selatan.

Abstract

Seasonally closed estuaries are vulnerable coastal systems in which alternating phases of mouth closure and opening strongly influence hydrodynamics, sediment transport, and benthic habitats. The Kungkai Baru Estuary on the wave-dominated western coast of Sumatra, Indonesia, is a small tropical estuary that predictably closes during the west monsoon and re-opens during the east monsoon. Although previous studies have documented major morphodynamic changes and shifts in macrozoobenthic communities between these phases, the associated near-bed sediment dynamics remain insufficiently understood. This study examined spatial and seasonal patterns of bed sediment texture using surface sediment samples collected at 21 stations during closed-mouth and open-mouth conditions and analysed through grain-size distribution and Folk–Ward statistics. Bed sediments were overwhelmingly sandy (>96% sand), but mean grain-size, sorting, and skewness showed clear spatial and seasonal variation. During the closed-mouth season, moderately well-sorted fine to medium sands dominated the middle and upper estuary, indicating reduced marine energy and greater retention of finer material. During the open-mouth season, coarser and more poorly sorted sands occurred near the estuary entrance, reflecting stronger marine influence and more active sediment exchange. These findings align with previously reported longitudinal patterns in macrozoobenthos and provide a sediment-based framework for understanding benthic habitat heterogeneity in seasonally closed tropical estuaries.
