The Influence of Difference Spatial Resolution of Satellite Images in Marxan Analysis for Marine Protected Area Design in Shallow Water Habitat of Kemujan Island, Karimun Jawa Islands

Marxan is one of the many methods of analysis used in determining the priority areas for the protection of both terrestrial and marine ecosystems of shallow waters. In the process, Marxan is very dependent on the data input on which to base its analysis. Worldview 2 imagery and Landsat 5 imagery was used as input in Marxan analysis. This image has a different spatial resolution and also gives different classification. Worldview 2 imagery that included imagery with high spatial resolution produces 4 shallow water habitat classifications. While, Landsat 5 images, which includes medium spatial resolution produces 3 classification. These data are then inserted into Marxan analysis to obtain the priority areas for conservation. From the results it can be concluded that high value in BLM which set for compact and clustered area showed insignificant best selected area from both satellite imagery. Contrast, lower value in BLM produce significant difference of best selected area and become more varied. It can be concluded that designing a new area for Marine Protected Area (MPA), the difference in image resolution will not have a considerable effect. Determine for small priority areas such as zoning, Worldview II image with high resolution will be more accurate
