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.

Abstract

Urban areas in Jakarta face significant pressure on clean water resources due to increasing population and anthropogenic activities. This research aims to conduct biomonitoring of the Situ Bambon Ciracas ecosystem, East Jakarta, by analyzing water quality and the community structure of macrozoobenthos, phytoplankton, and zooplankton as bioindicators. A descriptive quantitative method was used, involving measurements of water physical-chemical parameters (TDS, TSS, pH, BOD, COD, Total-P) and identification of aquatic biota. The results indicate that the water quality of Situ Bambon Ciracas is lightly to moderately polluted, dominated by organic compounds. BOD (5−34.67 mg/L) and COD (17.05−193.56 mg/L) values consistently exceeded the Class 3 water quality standards, and TDS showed an increasing trend. The biota community structure reflects these conditions: macrozoobenthos showed moderate diversity (H′=1.2, E=0.6). Phytoplankton (H′=3.12−3.2, E=0.74−0.76) and zooplankton (H′=2.11−2.16, E=0.76−1.95) showed high diversity and evenness, but were dominated by bioindicator species tolerant to organic pollution (e.g., Oscillatoria sp., Nitzschia sp., Colpoda sp., Closterium sp.). The positive correlation between the abundance of these bioindicator species and high BOD and COD confirms organic waste as the main driver of ecological change. In conclusion, the Situ Bambon Ciracas ecosystem is under significant anthropogenic pressure. The dominance of pollution-tolerant species, despite existing diversity, highlights the urgency of comprehensive management and restoration efforts to maintain the sustainability of this urban lake.
