Abstract

Halophila spinulosa (R. Br.) Aschers is a type of seagrass found in Indonesia with limited distribution. One of the areas where Halophila spinulosa is found in the Bangka Belitung Islands. Although found in the Bangka Belitung Islands, information on this type of seagrass is very limited. The objectives of the study were to identify morphological characters, identify types of seagrass associated with Halophila spinulosa and present a distribution map of Halophila spinulosa in the Bangka Belitung Islands. The research method for seagrass morphological characters is based on field data in the form of photographs, then compared with identification sources from books and research journals. The seagrass distribution map was determined based on a literature search from 2015 to 2022 and then a map was made using Arcmap 10.8 software. The results of the research on the morphological characters of Halophila spinulosa species can be seen from the shape of the roots, rhizomes, leaves, flowers and fruit. This type of root form is unbranched root (simple root) and each node on the rhizome has one root. Compound leaves are elliptical in shape. These leaves are paired, in opposite positions, located in one plane, arranged obliquely around the stem and have serrated leaf tips. The distribution of Halophila spinulosa seagrass in the Bangka Belitung Islands is spread in the areas of Central Bangka Regency, South Bangka Regency and Belitung Regency. Halophila spinulosa species are often found mixed (associated) with seagrass species Halodule uninervis and Oceana serrulata.

Abstract

Sampur Beach is one of the beaches in Central Bangka Regency with tin mining activities and a fishing area. Heavy metals in the human body can disrupt the work of enzymes and metabolism, causing cancer and mutations. This study aims to determine the status of heavy metal Pb and Cu contamination in the surface sediments of Sampur Beach. Heavy metal analysis uses the Atomic Absorption Spectrophotometry (AAS) method. The research results show that the condition of the sediment texture at Sampur Beach has a sandy to clayey sand substrate (83.09%-94.89%) and has a low Total Organic Matter (BOT) value (0.96-1.54%). The contamination factor values for metals Pb (0.00026 – 0.00036) and Cu (0.00285–0.00298) are low while the enrichment factors are high for metals Pb (95.69-220.44) and Cu (1090.89). –2084.60) which indicates the presence of anthropogenic input in addition to natural input. The geoaccumulation index for Sampur Beach is low for Pb (-12.502 to -12.038) and Cu (-9.042 to -8.975) and the PLI value for Pb and Cu metals (0.00087–0.00103) is not polluted to slightly polluted.

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

Abstrak Pantai Matras merupakan salah satu pantai yang ada di Kepulauan Bangka Belitung yang di jadikan sebagai tempat wisata. Peta batimetri merupakan data spasial yang berisi informasi kedalaman (informasi batimetri) suatu wilayah perairan. Penelitian ini bertujuan untuk mengetahui perubahan batimetri dalam rentang waktu tahun 2015, 2019 dan 2021. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan teknik pengambilan data purposive sampling meliputi data primer dan data sekunder. Hasil penelitian menunjukan bahwa pada tahun 2015-2019 total perubahan kedalaman yang terjadi pada garis cross section rata-rata sebesar 0,805 m dan total pendangkalan rata-rata sebesar 0,165 m. Pada tahun 2019-2020 total perubahan kedalaman yang terjadi rata-rata sebesar 7,145 m dan total pendangkalan rata-rata sebesar 0,492 m. Perubahan ini menyebabkan terbentuknya ceruk-ceruk disekitar breakwater (area A) dan disekitar arah laut (area B) yang disebabkan oleh penambangan timah.

Abstract

Matras Beach is one of the beaches in the Bangka Belitung Islands which is used as a tourist spot. A bathymetric map is a spatial data that contains depth information (bathymetry information) for a water area. This study aims to determine changes in bathymetry in the 2015, 2019 and 2021 timeframes. The method used in this study is a descriptive method with a purposive sampling data collection technique including primary data and secondary data. The results showed that in 2015-2019 the total change in depth that occurred at the cross section line was an average of 0.805 m and an average total shallowing of 0.165 m. In 2019-2020 the total depth change that occurred was an average of 7.145 m and an average total shallowing of 0.492 m. This change causes the formation of crevices around the breakwater (area A) and around the sea (area B) caused by tin mining.

Abstract

Gelasa Island has a coral reef ecosystem as a habitat for biota including coral reef fish, turtles, and others. The coral reef has been damaged due to anthropogenic activities. The purpose of the study was to determine the percentage of coral reef cover and the abundance of coral reef fish. The study was conducted in March 2024 in the waters of Gelasa Island. The method used was UPT (Underwater Photo Transect) for coral reefs and UVC (Underwater Visual Census) for coral reef fish, and the PAST 4.03 application to determine the diversity, uniformity, and dominance index. The results of the study showed that the percentage of coral reef cover in the waters of Gelasa Island was in the good category with an average of 52.42%. The abundance of coral reef fish was 49,114 ind/ha in the very rare category. The highest abundance of coral reef fish species was Neopomacentrus anabatoides, Pomacentrus alexanderae, and Caesio cunning. Based on the category, major fish have the highest abundance. The diversity value is in the moderate category, the uniformity value indicates an unstable community, and the dominance value is in the low category.

Abstract

Perairan pesisir Kota Pangkalpinang mengalami pendangkalan yang disebabkan oleh tingginya aktivitas antropogenik maupun peristiwa alamiah, sehingga dapat merubah pola dan karakteristik sedimen pesisir pantai baik secara fisik ataupun kualitas. Upaya penanggulangan masalah tersebut salah satunya dibangun breakwater atau pemecah gelombang. Tujuan dari penelitian ini untuk mengetahui karakteristik sedimen, nilai Total Suspended Solid (TSS), dan nilai laju sedimentasi di perairan pesisir Kota Pangkalpinang menggunakan sediment trap. Penelitian ini menggunakan metode purposive sampling yaitu menentukan lokasi pengambilan sampel berdasarkan pertimbangan. Penelitian dilakukan pada bulan februari 2023 dengan 8 titik stasiun. Menggunakan dua jenis data, yaitu data primer dan sekunder. Berdasarkan penelitian yang telah dilakukan, didapatkan hasil karakteristik sedimen yaitu lempung, lempung berpasir, pasir dan pasir berlempung dengan nilai TSS tertinggi berada di stasiun 1,3,7,dan 8 yang melewati baku mutu air laut berdasarkan PP RI No. 22 tahun 2021, sedangkan untuk nilai massa dan volume laju sedimentasi berkisar 0,23-2,33 gr/cm2/hari dan 0,60 – 1,91 mg/cm2/hari.
