Abstract

Coral reefs are vital tropical ecosystems formed by marine biota that produce calcium carbonate, primarily corals, in collaboration with other seabed and water column organisms. However, they face increasing threats such as bleaching, pollution, sedimentation, and ocean acidification, which weaken their structure and resilience. Indonesia, as an archipelagic nation, is home to extensive coral reefs, including those around Gili Ketapang, a small island located approximately 10 kilometers off the northwest coast of Bali, within the boundaries of West Bali National Park. Monitoring these reefs is crucial for conservation, yet traditional field surveys are often costly, time-consuming, and limited in coverage. To address this, remote sensing offers a more efficient and cost-effective approach, enabling large-scale and long-term monitoring while covering remote areas that are difficult to assess through direct observation.One of the key techniques in remote sensing for coral reef mapping is the Lyzenga algorithm, which minimizes the effects of water depth variations in optical imagery. When combined with high-resolution satellite data, it improves reef detection and analysis, making remote sensing an invaluable tool for marine ecosystem studies. Landsat 8, equipped with the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS), provides 30-meter spatial resolution imagery suitable for large-scale reef assessments. Its multitemporal capabilities allow researchers to analyze changes in coral reef conditions over time, detecting stressors such as bleaching, sedimentation, and pollution. By integrating the Lyzenga algorithm with multitemporal Landsat 8 data, researchers can enhance reef monitoring accuracy, supporting policymakers in implementing effective conservation strategies to ensure long-term coral reef sustainability
