Pemanfaatan Unmanned Aerial Vehicle (UAV) untuk Identifikasi Penggunaan Lahan di Kampung Nelayan Sebrang Medan Belawan Kota Medan

Abstract

The existence of remote sensing technology using Unmanned Aerial Vehicles (UAV) can facilitate the identification of land use in coastal areas, one of which is Sebrang Fisherman Village located in Medan Belawan District, Medan City. Unmanned Aerial Vehicles (UAVs) are known to be efficient in mangrove mapping and monitoring due to their spectral and spatial characteristics that can be detected easily. This is in accordance with the location of Sebrang Fisherman Village, where most of the land use is mangrove forest. This research aims to identify the type of land use in Sebrang Fishermen Village using Unmanned Aerial Vehicle (UAV) and to find out the activities of the community in Sebrang Fishermen Village, Belawan Medan City. The method used in this research is the processing of aerial photographs that produce orthomosaic for land use identification through visual interpretation method or on screen digitization, to get the accuracy results of Ground Control Point (GCP) and Independent Control Point (ICP) obtained through Geometric accuracy test Root Mean Squar Error (RMSE), and descriptive field observations. The results showed that the processing of aerial photographs produced a spatial resolution (ground sampling distance/GSD) of 2.84 cm/pixel, the number of aerial photographs connected (aligned) was 800 photos, the Root Mean Squar Error (RMSE) value was 0.199 meters and the CE09 value (90% horizontal accuracy) obtained was 0.303 meters. There are 17 types of land use in Sebrang Fishermen Village, namely Mosque, Musholla, Elementary School (SD), Kindergarten (TK), Early Childhood Education (PAUD), Pondok Baca, Posyandu, Settlement, Badminton Field, Playing Field, Gymnastic Field, Mangrove Forest, Dock, Public Cemetery, Water Body, Cast / Cement Road, and Cages with a land area of 20 ha. Community activities in Sebrang Fishermen Village still depend on the mangrove forest ecosystem, such as catching shrimp and crabs, fishing, raising fish in cages, and becoming a tour guide.
