Abstract

Mangrove is the largest ecosystem in Berbak-Sembilang National Park (BSNP) South Sumatra. Mangrove has capability to absorb carbon dioxide through photosynthesis then store it in biomass, that known as Carbon sink. The purpose of this research was to estimate the ability of carbon fixation through the photosynthesis mechanism in the mangrove area of BSNP South Sumatra. This study was conducted in July-August 2017, at 12 observation stations. Data of carbon fixation through photosynthesis was estimated by using Leaf Area Index (LAI) method. The estimation of carbon fixation by photosynthesis was done for 17 dominan mangrove species in BNSP South Sumatera. The average amount of carbon absorbed by mangrove vegetation through photosynthesis mechanism in BNSP South Sumatera was 204.91 kg/ha/day. Avicennia marina and Rhizophora apiculata were the mangrove community that showed highest capability to absorb carbon through photosynthesis around 553.43 kg C/ha/day and 401.99 kg-C/ha/day, respectively. Individually, B. cylindrica had the highest capability of carbon fixation by photosynthesis mechanism (10.95 kg-C/ha/day). Our research recommended three mangrove species (A. marina, R. apiculata and B. cylindrica) for restoration species to increase carbon sink in BNSP South Sumatera based on their photosinthesis performances.

Abstract

The leaves of R. stylosa are a potential source of bioactive compounds for health and pharmacology. The composition of bioactive compounds in the leaves can be influenced by the ecological conditions and geographical location of this small island. This study aims to evaluate the toxicity and composition of bioactive compounds that are toxic in mangrove leaf extracts of R. stylosa from Maspari Island in coastal South Sumatra. A total of 1 kg of R. stylosa leaf samples were taken from Maspari Island then washed thoroughly to remove dirt, cut into small pieces, and dried in the sun using the indirect sunlight method covered with black cloth. The dried leaf samples were then pulverized into powder, and as much as 100 grams of fine powder was macerated with 96% ethanol solvent in a ratio of 1:10 (b/v). The maceration process was carried out for 1 x 24 hours, then the maceration solution was filtered and evaporated using a rotary evaporator at 60°C to become a concentrated extract. Toxicity tests were carried out using the Brine Shrimp Lethality Test (BSLT) method, while the identification of toxic bioactive compounds was carried out through phytochemical tests, total phenol tests, and GC-MS analysis. The test results showed that the LC50 value of R. stylosa leaf extract was 393 mg/mL (moderately toxic). The total phenol content was 442.82 (gGA/g), and the bioactive compounds identified included alkaloids, flavonoids, saponins, terpenoids, and acids such as Hexadecanoic acid, methyl ester, and trans-13-Octadecenoic acid, methyl ester.

Abstract

The distribution of total suspended solids (TSS) in coastal waters significantly affects water turbidity and light penetration, which affects aquatic ecosystems. The research aimed to compare the accuracy of algorithms using Sentinel-2A imagery to map the distribution of TSS in Ketapang Waters, South Lampung. Polynomial regression analysis and validation tests using R² and RMSE were performed to assess accuracy. The results showed that the Laili algorithm performed better, achieving an R² value of 0.9723 and a lower RMSE of 0.639, with TSS concentrations ranging from 17.26 to 22.90 mg/L. The derived third-order polynomial regression model y = -0.0228x³ + 1.3401x² - 25.16x + 170.08 effectively predicted TSS concentrations. Spatial distribution analysis showed higher TSS levels near the coastline, likely due to sediment input from human activities and natural hydrodynamic processes, which gradually decreased towards the offshore area. These findings demonstrate the potential of the Laili algorithm for remote sensing-based water quality monitoring in dynamic coastal environments. Future research should include seasonal variations and explore the integration of multiple algorithms to improve the accuracy of TSS estimation and better understand temporal fluctuations in coastal sediment dynamics.

Abstract

Maspari Island is the only small outermost island located in the southern part of Bangka Strait, included in the coastal area of Ogan Komering Ilir Regency, South Sumatra. The island harbors a mangrove ecosystem that is believed to play a significant role in climate change mitigation through carbon storage. This study aims to identify mangrove species and measure carbon stock estimates in upper-stand biomass, lower-stand/root biomass, and sediment. Identification of mangrove species using a vegetation analysis approach. Transect plots measuring 10 m × 10 m were parallel to the coastline at 6 observation station points. The diameter of vegetation at the tree and sapling levels was measured at a height of 1.3 m from the ground surface. Carbon stock estimates were calculated using allometric equations and sediment carbon analysis methods. The results identified seven mangrove species: Avicennia marina, Bruguiera sexangula, Ceriops tagal, Excoecaria agallocha, Rhizophora apiculata, Rhizophora stylosa, and Sonneratia alba. Estimated carbon stocks of mangrove stands at all stations reached 3,443.42 tC/ha, with an average of 573.90 tC/ha, while carbon stocks in roots amounted to 862.96 tC/ha, with an average of 143.83 tC/ha. The total estimated carbon stock of mangrove sediment at all stations was 240.71 tC/ha, with an average of 40.12 MgC/ha. Sonneratia alba provided the highest carbon absorption, reaching 3,059 tC/ha for the upper stand and 697.80 tC/ha for the lower stand. Considering the contribution of the carbon storage potential in Maspari Island, this study suggests extending the investigation of the mangrove carbon fixation in other small islands in Indonesia, especially for the S. alba species.   Keywords: carbon stock, mangrove, Maspari Island, sediment, carbon stock, Sonneratia alba
