Abstract

Peatlands are wetland ecosystems that originate from piles of rotting organic material on the surface of the soil. Peatlands have unique conditions that are not found in other land system units, these conditions include having a high biomass value and carbon storage capacity. Jambu Baru Village is one of the villages located on a peatland unit with ecosystem conditions that have not experienced major changes or conversion of function. Field measurements aim to test and validate the value of soil biomass and carbon content in peatlands. The greenness index model from Sentinel 2A satellite imagery is used as the main basis for determining sampling plots for biomass measurements in each class of greenness index for each land cover in the field. The research results showed that the greater the diameter and height of the plant, the higher the biomass content and carbon stock, high stands obtained a biomass value of 14.95 kg with a carbon stock of 20.36 kg; medium stands obtained a biomass value of 9.08 kg with a carbon stock of 7.33 kg and low stands obtained a biomass value of 0.89 kg with a carbon stock of 0.42 kg. In this research, results were also obtained which showed that the tree and pole sources had the highest biomass among the other sources, 24.04 kg with 27.68 kg of carbon. The results of calculating biomass and carbon stock values for the wetland ecosystem in Jambu Baru Village are presented in spatial modeling in the form of a map of estimated biomass and carbon stock values.

Abstract

Kurau sub-district in Tanah Laut Regency is known to have a fairly extensive mangrove forest with great potential. One of the potentials is the variety of mangrove vegetation that grows in the forest. vegetation that grows in it. Knowing the diversity of mangrove forest species in Kurau sub-district aims to provide a scientific basis for in Kurau sub-district aims to provide a scientific basis for protecting and monitoring the forest. and forest supervision. The method used in the research is the technique of collecting data with purposive sampling and then analyzing with calculation of importance value index and Shannon-Wiener diversity index. Research The research was conducted based on the level of forest density consisting of high, medium and sparse forest density. high, medium, and sparse. The results obtained there are 11 types of vegetation that grow in mangrove forests and are dominated by the type of mangrove (Rhizophora mangle) which grows from seedling to tree level. Then followed by Rambai (Sonneratia caseolaris) and Api-api (Avicennia lanata). The level of species diversity in this mangrove forest is categorized as high with an index value of 5.5. high category with an index value of 5.46 for high forest density, 4.22 for medium forest density. While for sparse forest density included in the medium diversity category with a value of 2.34.

Abstract

Indonesia possesses the world’s largest mangrove forest area, which plays a vital role in global carbon regulation and coastal ecosystem services. However, these ecosystems are under increasing threat from anthropogenic pressures such as aquaculture expansion (especially shrimp farming), agricultural land conversion, and urban infrastructure development. These activities not only reduce forest cover but also compromise the ecological functions of mangroves, particularly their role as significant carbon sinks and oxygen producers. Given that mangroves have the highest carbon storage capacity per hectare compared to other forest types, their conservation is imperative in mitigating climate change. This study aims to assess the ecological and economic functions of mangrove forests in Kurau Sub-district, Tanah Laut Regency, South Kalimantan. Specifically, it quantifies aboveground biomass, carbon stocks, oxygen output, and the economic value of CO₂ sequestration. Data were collected through stratified random sampling based on vegetation density classes obtained from NDVI imagery, categorized into sparse, moderate, and dense classes. Field measurements focused on vegetation components from saplings to mature trees. Biomass was calculated using species-specific allometric equations, carbon stock was estimated by applying standard conversion factors, and oxygen production was derived using stoichiometric ratios. Economic valuation was conducted using a market-based approach, referencing global carbon pricing standards. The findings reveal that dense vegetation areas provide the greatest ecological benefit, with biomass of 54.72 tons/ha, carbon stock of 25.72 tons/ha, and oxygen production of 68.66 tons/ha. These ecological values translate into an estimated economic benefit of IDR 1.57 billion per year, indicating potential for integrating mangrove conservation with community-based development programs.
