摘要

Indonesia has lost more than 1.2 million hectare of mangrove since 1980 when mangrove forest cover was still 4.2 million hectare (FAO 2007). The objective of this study was to projection of mangrove cover changes in 2023. The study area is located in Tanakeke Island, Takalar District, South Sulawesi. The methodology of this study consisted of three main steps: (1) image analysis: geometric correction of Landsat images, preliminary analysis, and classification; (2) ground truth; (3) Cellular Automata Markov model (CA-Markov). Data input used for Markov Chain on two land use maps derived from two different times. Based on the results of the projection by using different intervals, the data with highre accuracy were obtained during ten year intervals with in which 35 iterations were used. In making a projection for the next 10 years (20230, an interval of 10 years (2003 to 2013) with iterations 35 was used. The simulation model trend, mangrove cover changes is a major concern which continued to be broken from 2013 to 2023 as simulated in the total area of mangrove cover is predicted to be 662.28 ha in 2023 (decreased by 238.83 ha) by using grid 30 m.
