Abstract

Mangrove ecosystems play a crucial role in maintaining the balance of coastal ecosystems and mitigating climate change due to their ability to absorb and store carbon. This study aims to estimate carbon stocks across different mangrove density levels on Bangko-bangkoang Island, Pangkep Regency, South Sulawesi Province. The methods employed include Sentinel-2 imagery analysis using the Google Earth Engine platform to identify vegetation density based on the Normalized Difference Vegetation Index (NDVI) and estimate carbon stocks using an allometric model and field data. The Sentinel-2 image analysis revealed that the mangrove vegetation cover on Bangko-bangkoang Island spans 16.04 ha. NDVI results show that mangroves in the low-density class cover 8.97 ha (56%), the medium-density class covers 3.71 ha (23%), and the high-density class covers 3.34 ha (21%). Field surveys confirmed the presence of three mangrove species on the island: Rhizophora mucronata, Rhizophora stylosa, and Sonneratia alba. Regression analysis conducted to assess the relationship between NDVI values and carbon stocks revealed the best model as an exponential function with the equation y = 0.0043e(11.726x), yielding a coefficient of determination (R²) of 0.683. The average carbon stock for the low-density class is 22.35 tons C/ha, for medium density is 67.1 tons C/ha, and for high density is 111.85 tons C/ha. These findings emphasize the important role of mangroves in climate change mitigation and provide scientific evidence for mangrove conservation efforts, particularly in enhancing vegetation density to optimize carbon storage.

Abstract

The Battang forest area in Palopo City faces ecological sustainability challenges due to pressure from human activities and low conservation awareness. Therefore, an integrated management approach combining ecotourism strategies, conservation awareness, and social participation is required to support forest conservation and ecological stability. This study aims to analyze the integrated role of ecotourism strategies, conservation awareness, and social participation in supporting forest conservation and ecological stability in the Battang area. The study used a quantitative approach with a survey method of 280 respondents consisting of members of forest farmer groups, local tourism actors, traditional leaders, and communities around the forest area. Data were analyzed using Structural Equation Modeling (SEM) to examine the relationships among variables. The results showed that conservation awareness (p = 0.000) and social participation (p = 0.000) significantly influenced forest conservation, while ecotourism strategies did not significantly influence (p = 0.193). However, all three independent variables significantly influenced ecological stability, with social participation as the most dominant factor (p = 0.000). The R² values of 0.779 for forest conservation and 0.810 for ecological stability indicate strong model predictive power. The findings indicate that conservation awareness and community participation are key drivers of forest conservation and ecological stability. Furthermore, the effectiveness of ecotourism initiatives depends strongly on social support and the presence of conservation-oriented values that encourage sustainable and non-exploitative resource use.
