Abstract

Mangroves play an essential ecological roles, such as providing habitats for various organisms and contributing to reducing CO2 emissions from human activities. These emissions are one of the main causes of global warming and climate change. This study aims to analyze the litter production rate and carbon content of mangrove litter in Sungai Nibung Village, Kubu Raya Regency, West Kalimantan. Sampling of mangrove litter was conducted for 14 days using a 1x1 m2 litter trap with a mesh size of 0.2 cm. The litter traps have been placed in 9 stations. Litter samples were collected on the 7th and 14th days, including parts of mangroves (leaves, twigs, flowers, and fruits) that naturally fell. Result of the study showed the total litter production rate ranged from 4.95 to 30.07 tons/ha/year, and the findings reveal a clear hierarchy in litter production with the composition being leaves > twigs > propagules/fruits > flowers. Leaves litter production rate is notably high, followed by twigs which represent the second-largest portion, then fruits, and flowers. Meanwhile, the total carbon content varied across sampling station, accounting for 2.30–23.59 tons/ha/year. This research provides essential baseline data for Sungai Nibung Village and highlights the potential of mangroves as significant carbon sinks. The results can be utilized for ecosystem-based coastal management and mangrove restoration aligned with regional environmental policies.

Abstract

Myth is a story whose origin and author are unknown. The purpose of a Myth is to explain natural processes, the creation of the world, human races, traditional customs, political institutions, or religious rituals. In Pelangas Village, West Bangka, there is a tribe known as the Jerieng Tribe. This tribe has a tradition that is still practiced by its people, which the Sedekah Gunung tradition. This tradition is carried out every year to coincide with the 14th night full moon. Because the Sedekah Gunung ritual tradition is a traditional procession that cannot be separated from people's belief in myth, this research aims to analyze the representation of myth in the Sedekah Gunung ritual using semiotic theory by Charles Sanders Peirce. This research uses descriptive qualitative methods with data collection techniques in the form of a combination of interviews, observation, documentation. The results of this research found several ritual practices in Sedekah Gunung which symbolize the Jerieng Tribe's belief in the sacredness of the Sedekah Gunung ritual, belief in the myth of the symbiotic relationship between humans and nature through the practice of giving and receiving, as well as the respect and communication of the Jerieng Tribe towards nature through Sedekah Gunung.

Abstract

The Bangka Belitung Islands Province has a mangrove ecosystem covering an area of 273,692.81 hectares. These ecosystems play a crucial role in mitigating greenhouse gas emissions through the sequestration mechanism, which involves absorbing carbon from the atmosphere and storing it in the form of biomass. Human activities around these areas, such as the flow of tailings from artisanal mining (TI), have caused damage to these ecosystems, leading to a reduction in one of the primary carbon dioxides (CO2) absorbers. This study aims to support the sustainable management of mangrove conservation areas in efforts to reduce the impact of global warming. Sampling stations were determined using purposive sampling, with the collection of substrate carbon, biomass, and carbon samples, as well as water quality parameters at Takari Beach. The results showed that the water temperature was 28°C, salinity ranged from 25 to 27 ppt, and pH ranged from 5 to 8,5. Four mangrove species were found at two stations: Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba, and Lumnitzera littorea, totaling 185 trees. The mangrove biomass was measured at 27,10636 tons/ha, and the below-ground carbon stock was recorded at 12,74 tons/ha.

Abstract

The mangrove forest ecosystem in East Kurau Village is a 148-hectare area that has the potential to reserve carbon. This research aims to identify the composition of mangrove vegetation types and analyze the potential for carbon stocks reserved in tree stands and sediments in the mangrove forest area in East Kurau Village. The method used to identify the composition of the mangrove vegetation types is a 10m x 10m plot. The tree biomass measurements were implemented using the no-logging method using allometric equations. The measurement of the sediment analysis was using Walkley & Black method. The result of the mangrove types composition in the East Kurau Village mangrove forest ecosystem consisted of 6 genuine/true species: Sonneratia alba, Rhizophora apiculata, Xylocarpus granatum, Acrostichum aureum, Bruguiera gymnorrhiza, and Bruguiera hainesii. The estimated carbon reserves in East Kurau Village's mangroves are 3.207, 29 tons/ha. The mangrove tree biomass of 57.966,57 kg/m2 and 18,44 % on the percentage of carbon content in the sediments.

Abstract

The high activity of catching Shark Ray (Rhinidae) have a big impact on the population and affect the balance of the marine ecosystem. This is supported by the characteristics of stingrays that have a lower reproductive ability, slower growth and higher risk of death. Lack of database information, relating to the Shark Ray can reduce oversight or regulations governing the production of the total catch. So the condition is feared impact on the survival of Shark Ray, especially in Bangka Belitung. One of the important databases that must be done is the accurate identification of fish species Shark Ray as a reference in determining the conservation status. The purpose of this research is to identify the molecular basis Shark Ray and the conservation status of the Shark Ray landed on Bangka Island. Shark Ray samples obtained from a source of potential landing in Bangka Island, namely PPN Sungailiat (Bangka Regency), TPI Ketapang (Pangkalpinang City) and TPI Kurau (Central Bangka Regency). The research method consists of three stages: collection of samples, the molecular identification (mtDNA Cytochrome Oxidase Subunit 1 / COI gene), phylogenetic analysis and conservation status of Shark Ray. The results of the COI gene nucleotide character matching were performed by using the BLAST program integrated into GenBank pages and showed that the three samples of Shark Rays were identified as Rhina Ancylostoma species (Bowmouth guitarfish, Shark Ray) with a rate of similarity of 100%. Based on data from the IUCN Red List, the species Rhina Ancylostomain the category of Critically Endangered (CR) and based on the status of trade, at the 18th CoP meeting in Geneva, on August 2019, CITES has added Wedgefishes (Family Rhinidae) in Appendix II.
