Utilization of Unmanned Aerial Vehicle (UAV) for Tidal Flood Study Related to Land Subsidence in Muara Angke, North Jakarta

Abstract

The Jakarta coastal location is placed in North Jakarta and borders the Java Sea. However, coral reefs have suffered widespread degradation in current years because of the effect of human disturbances and herbal elements on biodiversity and surroundings functions. It is thought that human sports cause 90% of coral reef harm and 10% is due to weather change. This could have an effect on excessive tidal waves, which purpose tidal flooding in coastal regions like Muara Angke. Land subsidence contributes to the phenomenon of tidal flooding in Jakarta. This tidal flood inundates components of the coastal plains or locations decrease than the excessive tide sea level. The method for determining the pool of water that floods the Muara Angke area is by knowing the highest tide and the slope of the area. This can make it easier to predict inundated areas. The tool used to detect the slope of the area using UAV. The results of a drone-based Digital Elevation Model (DEM) are more accurate. A tidal flood in Muara Angke is predicted to result in 5,82 ha using an elevation model. Increased exposure to flooding is a result of land subsidence. This is due to the HHWL's elevation of 0.73 meters above MSL. However, the Muara Angke loss estimate came to 99,5 million Rupiah, covering a total area of 2.72 ha and 0.43 ha (road).
