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

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

Mangrove ecosystems are similar to other forest ecosystems in that they play a role in absorbing CO2 from the atmosphere. Mangrove ecosystems can store more carbon compared to most rainforests. This is because mangrove plants utilize CO2 for photosynthesis and store it in the form of biomass and sediments. The purpose of this research is to determine the potential of mangrove ecosystems in absorbing and storing carbon, particularly the content of below-ground carbon and Biomass from several locations on Lepar Island. The data collection method used systematic sampling, where the placement of sampling plots had regular distances from the sea to the land. Substrate samples were taken using a core sampler tool and analyzed using the Loss of Ignition (LOI) method to determine carbon content. The research results showed that the average soil density at all stations was 1.0 g/cm3. The average percentage of organic carbon at all stations was 0.09 C%. The average total carbon content at all stations was 105.73 tons/ha. Mangrove forests are capable of storing a large amount of carbon in both biomass and sediments.

Abstract

East Timur Village has pristine mangrove areas. It has much potential that can be developed, one of which is mangrove ecotourism which is directly managed by the people of East Kurau Village. Mangrove ecotourism still need to optimize its potential tourism destination object. The research aims to formulate a development strategy for Mangrove Ecotourism in East Kurau Village, Koba District, Central Bangka Regency. The research uses a qualitative approach with IFAS (Internal Factors Analysis Strategy) and EFAS (External Factors Analysis Strategy). The data is collected through in-depth interviews with related stakeholders, questionnaires distributed to tourists, and field observations. Moreover, the indicators used to measure the data include accessibility, infrastructure, and other supporting aspects. The ecotourism strategy is answered using the SWOT analysis method. The results from matrix calculations of IFAS and EFAS show that the value of the X-axis was 0.93 and of the Y-axis was 0.88. This indicates that the strategic position was at the quadrant I, with the strategic formulation of S-O (aggressive strategy). Some strategies have been formulated, including: Supporting mangrove conservation and creative economic business management; Establishing cooperation in providing supporting infrastructure; Optimizing cooperation in providing education on the benefits of mangroves; and Increasing the government’s commitment to mangrove development.

Abstract

The impact of reactions free radical compounds can cause various health problems such as inflammation, aging, and cancer. Therefore, to avoid damage caused by free radicals, the body needs an important substance, antioxidants. Natural antioxidants are more recommended than synthetic antioxidants because synthetic antioxidants must be in accordance with the prescribed dose because they can cause side effects that are harmful to the body. This study aimed to determine the antioxidant activity of the extract and fraction of the Pelawan (Tristaniopsis merguensis Grifft.) stem extract. Antioxidant testing was carried out using the DPPH method on extracts and fractions of Pelawan stem extract (T. merguensis Grifft.). In addition, qualitative phytochemical testing was also carried out on extracts of the stems of Pelawan (T. merguensis). The results of the three solvent fractions, n-hexane, ethyl acetate, and methanol, were positive for flavonoid and phenolic secondary metabolites. Meanwhile, the antioxidant activity in reducing DPPH radicals in the methanol extract fraction of pelawan stems had a very strong activity with an IC50 value of 36.33 g/mL, while the ethyl acetate and n-hexane extract fractions had a very weak antioxidant activity with an IC50 value of 387.43 μg/mL dan 759.88 μg/mL.

Abstract

The mangrove ecosystem is one of the most productive ecosystems on earth. This ecosystem provides a lot of functions for the living organism inhabiting here, such as fishes, mollusks, echinoderms, crustaceans, ect. The mangrove crab is one of the common crustaceans that can be found in the mangrove. This Purtunidae crab is very popular due to their role in the food chain as well as for the economic income that has a high value in the market. However, overexploitation may decrease the crab population. This study aimed to investigate the abundance and occurrence of the mangrove crabs from Munjang mangrove, Bangka Belitung Island from August 2020 to June 2021 using baited traps with the line transect method at four zones. A total of four species of mangrove crabs, Scylla olivacea, S. paramamosain, S. serrata and S. tranquebarica, were found in this location and dominated by S. serrata. Shannon diversity index (H’) was a in low category (<1), evenness index range (J) from 0.35 to 0.89, and there was dominant species in this study. The bed sediment iswas dominated by the muddy clay substratum except in zone 4 with sandy. Overall, this location is a suitable habitat for the Scylla spp. And better management is urgently needed before these crabs are exploited by humans.
