This study aims to determine the potential volume of raw dried seaweed Kappaphycus alvarezii in Parigi Moutong District, Central Sulawesi Province, Indonesia. The determination based on the analysis of land suitability for seaweed farming, using: (1) Geographic Information Systems (GIS); and (2) Analysis of Waters Carrying Capacity. Satellite imagery used were Aquamodis 2013 and LANDSAT 8. Subsequent processing using the software of ENVI 4.5 and ArcView GIS 10.2. Thematic maps were produced then overlayed to get the land suitability of seaweed farming. The results then analyzed to produce the water’s carrying capacity of 106,989.53 hectares. If the area converted in the form of a long line raft measuring 50 x 50 m, amounted to 190,204 units, consisting of: (1) 19,020 units of nurseries, and (2) 171,183 units of cultivation raft. If the average production of 0.545 tons drymaterials/raft/crop, the potential volume of raw dried materials amounting to 93,194.14 tons/crop.
