Abstract

This study aims to analyze the land suitability in the coastal area of Pulau Morotai Regency for whiteleg shrimp. The research was conducted in Raja Village. The observed parameters include infrastructure data such as distance to the market, distance to the highway, and distance to the hatchery. Water quality parameters are water temperature, salinity, dissolved oxygen (DO), water pH, total ammonia nitrogen (TAN), nitrite, nitrate, phosphate, and plankton abundance. Meanwhile, the observed soil quality parameter is soil pH. Land suitability analysis was conducted using geographic information systems and drones. The results show that the distances to the market, highway, and hatchery are >12 km, >5 km, and >12 km, respectively. Water temperature ranges from 15.40-27.10 ℃, salinity is 0 ppt, DO ranges from 1.00-2.20 mg L-1, water pH ranges from 6.00-7.00, TAN ranges from 0.001-0.043 mg L-1, nitrite ranges from 0.017-0.070 mg L-1, nitrate ranges from 0.005-0.045 mg L-1, phosphate ranges from 0.006-0.048 mg L-1, and plankton abundance is 2.3×109 cells L-1. Meanwhile, soil pH ranges from 4.00-7.00. The analysis indicates that the coastal area of Raja has 1000 Ha of marginally suitable land (S3) and 1000 Ha of unsuitable land (N) for brackishwater aquaculture development.
