Abstract

Oil palm has the ability to sequester carbon dioxide stored as carbon stock. This study aimed to estimate carbon stock  in some age classes, to determine the relationship between Normalized Difference Vegetation Index (NDVI) and carbon stock, and to estimate the distribution of oil palm carbon stock in Landscape Sembilang Dangku. Estimation of carbon stock  were carried out at the non productive age plant phase namely <2 years, 2-3 years, and the productive plant age  phase namely 4-10 years and> 10 years. The carbon stock estimation used allometric equations. Landsat 8 Operational Land Imager (OLI) /Thermal Infrared Sensor (TIRS)  was analyzed to determine NDVI.  Making a map of the classification of carbon stock distribution using Software QGIS Las Palmas 2.18.0. The results showed that the carbon stock in the age class <2 years was 9.50 ton C/ ha, the age class of 2-3 was 9.62 ton C/ha, the age of 4-10 was 28.23 ton C/ha and in the age class> 10 was 79.83 ton C/ha. The relation between NDVI with carbon stock had a strong correlation (r = 0.9972) with regression equation Y = 638.13x - 242.65.  Carbon stock distribution  was  based on percentage of area as follows: <15 ton C/ha covering an area of 26.52%, 15-25 ton C/ha covering an area of 5.29%, 26-70 ton C ha covering an area of 35.41%, and > 70 ton C/ha 32.78%. Keywords: age class, carbon stock, landscape, NDVI

Abstract

Land cover change in coastal areas is a critical environmental issue that affects the ecological, social, and economic dimensions of local communities. The study purpose was to analyse the dynamics of land cover change and to examine community perceptions of its ecological, social, and economic impacts in Muara Gembong Sub-district, Bekasi Regency, West Java. Materials and methods. This study applied a mixed-methods approach, integrating Sentinel-2A satellite imagery analysis (2015–2025) with a perception survey of 100 purposively sampled respondents. Statistical analysis involved descriptive statistics and linear regression, while spatial data were analyzed using land cover classification, accuracy assessment, and spatial overlay. Results. The results indicate a significant conversion of mangrove forests and fishponds into settlements and open land. The community perceived these changes as having negative impacts on the coastal ecosystem (biodiversity loss and coastal abrasion), as well as on social aspects (reduced access to natural resources) and economic aspects (declining income of fishermen and fish farmers). However, some respondents also recognized new economic opportunities arising from land-use conversion. The integration of spatial analysis and community perceptions revealed a strong correlation between the locations of land cover change and the levels of socio-ecological-economic vulnerability of the community. Conclusions. Land cover change in Muara Gembong (2015-2025) was mainly driven by coastal abrasion, climate change, and human activities such as population growth and infrastructure development. These changes coused ecological degradation, social conflicts, and reduced community income. Nevertheless, local communities emphasized that ecological sustainability is essential for coastal resilience and recognized new opportunities through mangrove-based ecotourism an product diversification.
