Integrated Coastal Management Dynamic Models: A Case Study of Development Seaweed Cultivation in the Waters Luwu and Palopo Regency Bone Bay, South Sulawesi

Waters carrying capacity in seaweed of Eucheuma cottonii cultures should be a concernforoptimum seaweed culture. Carryingcapacity can determine by Ecological Footprint (EF) analysis, which in this research usefootprint production, and mas balance nitrate analysis. This research on Mei 2015 (1sttransitionalseason) and September 2015 (2ndtransitionalseason) in Luwu and Palopo, South Sulawesi. Map and land use analyzed with  geographic information systems (GIS).The results showed that theEcological Footprint production (EFP)in Luwu waters is 67,88 ton/capita/year, or equivalent to 235.823,93 tons/year.Based on the analysis of the availability of water for seaweed is 38.374,69 hectares, it can produce seaweed (biocapacity) for 922.928,96 tons/year and  the number of farmers that allows for use the waters is  13.595 capita. The Ecological Footprint  production (EFp) in Palopo waters is 3,08 ton/capita/year, or equivalent to 4.589,99 tons/year. Water availability analysis is 979,82 hectares are able to produce seaweed (biocapacity) for10.115,34 ton/year and the number of farmers that allows for use the waters is 3.276 capita. Based on the four scenario simulation management results of the development seaweed cultivation Eucheumacottonii in Luwu and PalopoRegency is based on the present waste input, pressing inputs of waste into the waters of 10%, 25% and 50% yield different waters biocapacity. The results comparison between biocapacity and Ecological Footprint, ecological status for  Luwu and Palopo waters are still in sustainable use.Based on those simulation results showed that in second scenario by pressing the waste input by 10% from the existing waste input, as well as assuming the availability of water utilizing the entire area of 38.374,69 hectares continuously (on the years scale of 2008-2030), it will produce the highest biocapacity waters in the amount of 8.257.274,94 tons/year. So with the management of seaweed in Palopo with second scenario, assuming the availability of water utilizing the entire area of 979,82 hectares will produce the highest waters biocapacity of 14.306,92 tons/year.
