GEOGRAPHIC INFORMATION SYSTEM-BASED MODELING AND ANALYSIS FOR SITE SELECTION OF GREEN MUSSEL, Perna viridis, MARICULTURE IN LADA BAY, PANDEGLANG, BANTEN PROVINCE
ABSTRACT: Green mussel is one
of important species cultured in Lada Bay, Pandeglang. To provide a necessary
guidance regarding green mussel mariculture development,finding suitable site
is an important step. This study was conducted to identify suitable site for
green mussel mariculture development using geographic information system(GIS)
based models. Seven important parameters were grouped into two submodels, namely
environmental (water temperature, salinity, suspended solid, dissolve oxygen,and
bathymetry) and infrastructural (distance to settlement and pond aquaculture).
Aconstraint data was used to exclude the area from suitability maps that cannot
beallowed to develop green mussel mariculture, including area of floating net
fishing activity and area near electricity station. Analyses of factors and
constraints indicated that about 31% of potential area with bottom depth less
than 25 m had the most suitable area. This area was shown to have an ideal
condition for green musselmariculture in this study region. This study shows
that GIS model is a powerful tool for site selection decision making. The tool
can be a valuable tool in solving problems in local, regional, and/or continent
areas.
