Abstract

Buleleng is located in the northern part of the island of Bali which is acknowledged for its marine tourism, dolphin habitat and black sand. Drone utilization for mapping is effective and efficient for observing, investigating, and monitoring coastal areas with high resolution and accuracy. A total of 37 mapping flight missions with consumer grade drones were carried out in the period 6 - 9 October 2022 covered 13.67 km of the coastal area of Lovina, Buleleng and its surroundings. High accuracy positioning is also used to improve mapping accuracy up to 1.09 m. The aerial map covers approximately 952.77 ha with shallow water benthic coverage of 247.12 ha. This study obtained the benthic characteristics of coastal benthic habitat which can be observed to a depth of 5 m. The results of the classification of aerial photos by visual interpretation showed that various classes of objects are fulfilled by various communities such as coral reefs and seagrass. In addition, there are artificial coral reef plantations by Indonesia Coral Reef Garden (ICRG) activity and sea turtles that were found in drone-based mapping.
