Abstract

Mangrove forests are a community of tropical and subtropical beach vegetation, capable of growing and developing in tidalareas. This study aims to obtain information on the type and density of mangrove species by using remote sensing applicationsand to obtain mangrove distribution profile based on tidal. This research has been conducted in Bangkobangkoang IslandTupabbiring Sub-district of Pangkep Regency in September-October 2016. This research covers species inventory, mangrovedensity level using Landsat 8 image with Acquisition 6 June 2016 and mangrove distribution based on sea tides. The resultsshowed that mangrove vegetation density conditions in Bangkobangkoang island were generally in good condition. The typesof mangroves on the island of Bangkobangkoang are Rhizophora stylosa, Rhizophora apiculata, Rhizophora mucronata,Sonneratia alba, and Avicennia marina. The dominant mangrove species are Rhysophora stylosa and Rhizophora apiculata.Mangrove distributed at the highest tide with Rhyzophora stylosa type will be submerged while at lowest tide generally nomangrove is submerged except on the western island with the same type of Rhyzophora stylosaKey words: Mangrove, Landsat-8, Density, Ddistributions profile

Abstract

Surface chlorophyll-a (Chl-a) distribution have been analyzed with seasonal variation during southeast monsoon in southern part of Makassar Strait and Flores Sea. Satellite data of Landsat-8 is applied to this study to formulate the distribution of chlorophyll concentration during monsoonal wind period. The distribution of chlorophyll concentration was normally peaked condition in August during southeast monsoon. Satellite data showed that a slowdown in the rise of the distribution of chlorophyll in September with a lower concentration than normal is likely due to a weakening the strength of southeast trade winds during June – July – August 2016. Further analysis shows that the southern part of the Makassar strait is likely occurrence of upwelling characterized by increase in surface chlorophyll concentrations were identified as the potential area of fishing ground.
