| Summary: | Benthic habitats in coastal areas are composed of diverse organisms and substrates such as seaweed, seagrass, algae, hard corals, dead corals, rock, and rubble. Understanding their distribution is essential for effective marine spatial planning and conservation. This study aimed to assess benthic habitat distribution around Tunda Island using Sentinel-2A satellite imagery and evaluate the classification accuracy. Field data were collected from March 5 to 7, 2024, using the photo transect method to identify key benthic classes. Image classification was performed using a Random Forest classifier, and accuracy was evaluated through a confusion matrix. The analysis identified four main benthic habitat classes: rock, rubble, seagrass, and hard coral. Habitat distribution generally followed a pattern across all stations—rock and rubble nearshore, transitioning to seagrass and hard coral further offshore. The areal coverage for each class was estimated as rock (31.89 ha), hard coral (31.29 ha), rubble (21.34 ha), and seagrass (11.99 ha). The classification achieved an overall accuracy of 69.86%, indicating that Sentinel-2A imagery combined with Random Forest classification holds promise for mapping benthic habitats in coastal environments like Tunda Island. |
