identifying leading aquaculture commodities in west java’s coastal industry: a multimethod regional analysis

The initial stage in agro-industrial development planning involves identifying high-potential raw materials. assessing commodity competitiveness requires a comprehensive analytical approach to ensure that decisions are both accurate and sustainable. the development potential of aquaculture-based agro-industries can strengthen linkages between upstream and downstream sectors, particularly between fishery production and processing industries. however, in four coastal regencies of west java province, aquaculture-based agro-industries have not yet been developed, despite aquaculture recording the highest export value at the provincial level. at present, the region remains dominated by manufacturing industries. this study aims to identify priority aquaculture commodities for coastal agro-industrial development. commodity competitiveness was assessed using five analytical methods: location quotient (lq), dynamic location quotient (dlq), sectoral contribution index (sci), growth ratio model (grm), and shift share analysis (ssa). a multi-method approach was employed to generate complementary results and enhance the validity of the superior commodity designation. the findings reveal that shrimp is categorized as a highly competitive commodity across all four regencies. these results serve as a strategic foundation for regional agro-industrial development policies and can be replicated in other coastal areas.
