Analysis of sustainability ecosystem mangrove management in Pangkah Wetan and Pangkah Kulon Villages Area, Ujungpangkah District, Gresik Regency, East Java Province
Mangroves provide several important functions such as gatherings, nurseries, living areas, and eating habitats. The best management plan designed for the conservation of mangrove wetlands must be considered as well as an ecological and social facility. The purpose of this study was to analyze the sustainability of mangrove ecosystem management from the ecological, economic, social, institutional and technological dimensions using the MDS (Multi Dimension Scaling) method through the RAP-MANGROVE (Rapid Assessment for Mangrove) approach in Pangkah Wetan and Pangkah Kulon Villages, Ujungpangkah District, Gresik Regency, East Java Province. The results of the study show that the sustainability index of the mangrove ecosystem in the Pangkah Wetan Village for ecological, institutional, and technological dimensions are less sustainable, while for economic and social dimensions are sufficiently sustainable; while in the Pangkah Kulon Village for ecological, social, institutional, and technology dimensions are sufficiently sustainable, while for economic dimension is sustainable. Based on the results of leverage analysis, it shows attributes that are very sensitive to the sustainability status of mangrove ecosystems, for the ecological dimension are fauna diversity in mangrove ecosystems, and coastline changes. The sensitive attributes in the economic dimension are a type of direct use mangrove ecosystems for community, and contributions mangrove ecosystem to increasing labor; while in social dimension are mangrove ecosystems damaged by community and community access to utilize mangrove ecosystems. The sensitive attributes in the institutional dimension are involvement of community institutions regarding mangrove ecosystem management and the existence of sanctions for violating regulations in the mangrove ecosystem; while in technological dimension are processing techniques for mangrove products, and the techniques for capturing biota in mangrove ecosystems. The results of the Monte Carlo analysis show that the overall dimensions in this study are adequate and valid (indicated by the difference between MDS and Monte Carlo <5%), while the Goodness of Fit analysis shows an S-stress value of <0.25 for each dimension, so the RAP-MANGROVE model in this analysis it is a good model and can be used to analyze the accuracy of the sustainability of mangrove ecosystem management.
