Abstract

Mangrove ecosystem rehabilitation based on a social-ecological systems (SES) approach is a holistic analysis that integrates ecological and social dimensions in coastal restoration and conservation efforts. The success of this rehabilitation is influenced by the complex interaction between environmental biophysical factors and governance dynamics, including government policies, public participation, and local wisdom practices. This study aims to map and analyze the dynamics of SES in a mangrove rehabilitation program. Data were collected using the rapid rural appraisal (RRA) method from June to August 2024. The study results were formulated into a conceptual model of the basic SES network for mangrove rehabilitation in Brebes Regency. The identified network model consists of 85 components (nodes) and 141 causal relationships (links). The research findings indicate that the managing resource actors (RAs) act as the central component (core of the network) that drives the sustainability of rehabilitation activities in the coastal areas of Brebes Regency. The synergy of roles between actors within this SES framework is crucial in increasing the effectiveness and sustainability of the program. It is expected to optimize ecological functions and provide socio-economic added value for coastal communities.

Abstract

Banten Bay is a busy water area with diverse activities, including capture fisheries, aquaculture, marine and land transportation, and industry, which are estimated to generate significant amounts of heavy metals that enter the water and accumulate in fish and shellfish. Some fishery commodities commonly found in Banten Bay included shellfish, such as blood cockles, green mussels, mud crabs, and blue swimming crabs. The study aims to monitor heavy metal contamination variations spatially and temporally of the shellfish in Banten Bay. Biota samples were taken for 6 months in Cengkok Coastal Waters (March–August 2019) and 3 months in Bojonegara Coastal Waters (August–October 2020). The heavy metal content was determined using an atomic absorption spectrophotometer (AAS). Pb and Cd concentrations in the flesh of the shellfish (blood cockles, green mussels, mud crabs, and blue swimming crabs) from the Cengkok and Bojonegara Coastal Waters ranged from 0.001 to 0.070 ppm and from <0.001 to 0.030 ppm, respectively. All measured heavy metal concentrations met the BPOM (2018) quality standards. Bioconcentration factors were generally <100, indicating low accumulation levels.  Blood cockles, green mussels, and mud crabs from Cengkok Coastal Waters were still safe for consumption in normal amounts, while the consumption of swimming crabs was strictly limited to 0.42 kg/week for adults and 0.11 kg/week for children. The same four species from the Bojonegara Coastal Waters were also considered safe for consumption in normal portions.
