Abstract
Rip current is being the major cause of the deadly accidents in Parangtritis Beach. This occasion can be prevented by mapping and monitoring the spatial pattern of rip currents at the location which rip currents are located. Rip current location can be identified by remote sensing data or aerial observations, such as Kite Aerial Photography (KAP). This platform is low cost and can be performed in coastal area due to the massive winds there. KAP has been widely used as the platform for mapping, and some of them are implemented in coastal area. This study aims to find out the ability of Kite aerial photography to identify the rip current location in Parangtritis Beach. From several flight tests, the photo mosaic of Parangtritis Beach has been generated after the KAP has flown at the minimum 3 m/s of the wind speed. KAP can be the great potentials in coastal monitoring, especially for rip current monitoring because it is low-cost, low-energy and provides actual information.

Summary
The physical characteristics, consist of wind, current and wave, can cause hazard to people at the beach. Rip current is the strong water current that flows from beach towards the sea, usually through the surfing line, and it can be occurred on a beach which has breaker wave [1]. Rip current occurred when the peak line of wave is parallel with coastal line [2]. This current happens every day with various intensity, from small current until heavy current that can drag people out towards the sea [3]. Rip current flows rapidly away the coast with the root on the coast line, the neck on the breaker zone, and the head’s shape is like mushroom. Rip current can be occurred due to the bathymetry influences, it can be occurred at the plain beach [4]
