Abstract

This research aimed to analyze blue carbon potential and mangrove ecosystem management in promoting climate change mitigation in Indonesia. The collected data included mangrove area data obtained through the Indonesian National Ecosystem Monitoring System (SIMONTANA). This research calculated the carbon stock using the global average of mangrove carbon stock. The results showed that the total blue carbon stored in mangrove ecosystems reached 3,267.87 Megaton Carbon (MtC). Papua and Kalimantan regions contributed the most significant potential, with 1,707.22 MtC and 608.17 MtC, respectively. The absorption of carbon dioxide (CO2) reached 11,982.21 MtCO2e. The most significant CO2 gas emissions absorption was observed in the Papua region, amounting to 6,259.80 MtCO2e, followed by Sumatra with 2,118.59 MtCO2e. This high potential value correlated with mangrove ecosystem management policies, such as conservation, restoration, and blue carbon monetization. Mangrove management for climate change mitigation was carried out through national and international cooperation to achieve the 26% to 40% emission reduction target. The existing management model of mangrove ecosystems focused on improving ecological sustainability with less orientation on improving community welfare. Implementing blue carbon monetization at the district level by involving the community as the owners or managers of the mangrove ecosystems is crucial.

Abstract

Research on the diversity of gastropods in the intertidal area of ​​Tanjung Air Panas Beach, Tulehu Village, Central Maluku Regency was conducted in November 2024. Gastropod samples were collected in 60 quadrants on 5 belt transects. All individuals obtained were identified to the species level and the number of individuals was counted. The results of the study showed that gastropods in the intertidal area of ​​Tanjung Air Panas Beach, Tulehu Village consisted of 9 species belonging to 1 subclass i.e. Caenogastropoda, 3 orders, namely Caenogastropoda, Littorinimorpha and Neogastropoda, 7 families and 8 genera. Nassarius globosus had the highest occurrence frequency and was found in all transects and all quadrants (100%), followed by Conus ebraeus which was found in 6 quadrants (10%) and then Canarium microurceus which was found in 4 quadrants (6.67%). The highest density is owned by N. globosus with 2,633 ind./m2 (87.78%) then followed by C. ebraeus with 0.117 ind./m2 (3.89%) and C. microurceus with 0.100 ind./m2 (3.33%). The Shannon diversity index (H’), Simpson dominance index (D) and Shannon uniformity index (E) are 0.59, 0.77 and 0.27, respectively. Based on the three indices, it can be concluded that the gastropod community in the intertidal area of ​​Tanjung Air Panas Beach, Tulehu Village has low diversity and uniformity with high dominance.

Abstract

Mangrove ecosystems have an important role in mitigating climate change through carbon sequestration. This study aims to determine the blue carbon potential of mangroves on the coast of West Muna. The research was conducted by measuring mangroves density using the quadratic transect method (10 m x 10 m) and measuring stem diameter (DBH). The values ​​of carbon stock and carbon absorption were analyzed based on the biomass values ​​calculated using the allometric equation of each mangrove species. The results showed that the total biomass, stock, and carbon absorption of mangroves on the coastal areas of West Muna were 211.9 tones/ha, 99.21 tones C/ha and 363.77 tones CO2-eq/ha. The largest contributors to total biomass, stock, and carbon sequestration are R. stylosa and S. alba species. In contrast, the species with the lowest contributors are B. cylindrica and B. gymnorrhiza. Differences in the ability to store carbon in each species are influenced by the structure of the mangrove community, including density, stem diameter and root type. Mangroves of the Rhizophora species have good carbon absorption capabilities. Besides that, it can also adapt well to the environment, so it is very good to be managed and bred in climate change mitigation efforts.

Abstract

Molluscs, especially bivalves and gastropods, make an important contribution to the formation of food chains in seagrass ecosystems. In addition, bivalves and gastropods are often used as biological indicators of aquatic environmental quality in seagrass ecosystems. The close relationship between seagrass beds, bivalves and gastropods can be seen in the expanse of seagrass ecosystems found on Buntal Island which is located in Kotania Bay, West Seram Regency. The potential of bivalves and gastropods, such as the diversity and community structure found in Buntal Island waters, is very important to study because the information is limited. This study aims to determine the diversity of bivalves and gastropods in the seagrass ecosystem of Buntal Island and to determine the community structure of bivalves and gastropods which include; density and relative density, abundance and relative abundance, and frequency of presence and relative frequency of presence. The research method used is quantitative. The results of the analysis of the potential of molluscs showed that the diversity of the composition of mollusc taxa found in seagrass ecosystems on Buntal Island was divided into 2 classes, 25 families, 37 genera, 52 species with a total of 3291 individuals. The mollusc with the highest score in terms of density, abundance, and frequency of presence belonged to Nassarius globossus.
