Abstract
Macroalgae in the rocky intertidal zones of West Java's southern coast provide essential ecosystem services, including carbon storage and marine stability. Using GIS and remote sensing, this study assesses seasonal spatial distribution and carbon sequestration potential of macroalgae across Karapyak, Sindangkerta, and Sayangheulang beaches. Biomass and carbon stocks varied seasonally, with Sargassum and Gracilaria identified as primary contributors. Average carbon stocks ranged from 0.6 to 1.14 tons.ha⁻¹ significantly higher than typical Indonesian seagrass levels (0.21–0.23 tons.ha⁻¹). Peak biomass reached 1050 gm⁻² at Sayangheulang during the dry season, emphasizing macroalgae's ecological roles in productivity and habitat provision. However, environmental degradation threatens these zones, highlighting the need for conservation. The study reinforces the role of macroalgae in blue carbon storage and coastal ecosystem health.
