Fifteen hexagonal artificial reefs were placed on Tlangoh Beach, Bangkalan, Madura Island, in 2022. The reefs have been planned to reduce shoreline erosion that has been occurring in this location since 2020. Pertamina Hulu Energy – West Madura Offshore (PHE – WMO) will deploy more artificial reefs in their CSR (company social responsibility) program. The effect of the artificial reefs on reducing shoreline erosion was usually observed by the change of morphology and shoreline in the study area. The study of shoreline change has gained significant attention due to its substantial impact on coastal environments. Understanding the dynamics of shoreline alteration is crucial for managing and planning coastal development and preserving coastal ecosystems such as artificial reef deployment. Scientists and researchers have developed a generalized shoreline change model called GENESIS to aid in this understanding. This software provides a valuable tool for predicting and analysing coastal erosion and accretion patterns. This paper discusses the shoreline change model in Tlangoh Beach, Bangkalan Madura, after deploying artificial reefs using GENESIS software. The model shows that the length of the artificial reef layout influences the developed shoreline. The longer the reef placement, the more sediment accumulates in the study area
