LiDAR application of intertidal coastal zoning for aquaculture in Wolo Village, Kolaka, Southeast Sulawesi

Abstract

Coastal Zones or Regions have abundant natural resources, support polluted areas' welfare and are a source of regional income. Wolo Village coastal resources supporter a regional economy covering 3.44 square kilometers, as it is presented in the RTRW master plan and included in the regional-based maritime and fisheries and economic development concept (Minapolitan). The characteristics of the Wolo village coast support various types of aquaculture which are beneficial to its population. However, for sustainable growth, there is a need for aquaculture zoning of the intertidal areas. This zoning will provide the means to maintain the balance of coastal resources, ensures sustainability and it will support government developing programs. Intertidal coastal area zoning can be carried out by a zoning system that obtains space utilization in accordance with a criterion that supports the sustainable development of existing coastal resources and follows the RTRW master plan. To determine the physical condition of region spatially, DTM and DSM data obtained from Light Detection and Ranging (LiDAR) data can be used. The sustainable zoning boundaries for each cultivation would be found by using Geographic Information System. The results obtained using this method are that most of the coast in Wolo village included in Zoning III, which has potential for the development of coral reefs cultivation and Zoning I, which has the potential for the development of seaweed cultivate. From the obtained results, it can be concluded that the potential on the coastal of Wolo Village, as a producer of seaweed that can be further developed in accordance with sustainable zoning program and support the national Minapolitan Area.
