| dc.description.abstract | Monitoring the rehabilitation of mangroves is necessary to evaluate the success of the rehabilitation program. Unmanned Aerial Vehicle (UAV) technology can expedite the mapping of mangrove rehabilitation success because drone imaging results have high spatial accuracy and. The aim of this research is to assess the success of mangrove forest rehabilitation in Tanjung Rejo Village, Percut Sei Tuan Subdistrict, Deli Serdang District, North Sumatera, and to compare the effectiveness of UAV in identifying the success of mangrove rehabilitation. This research was conducted using the automatic seed calculation method with template matching using the eCognition software and assessing the accuracy level using the calculated data in ArcMap software. The results of aerial photography at a flying altitude of 50 meters yielded 3.313 photos with a drone flight time of 169 minutes. At a flying altitude of 80 meters yieldied 1.480 photos with a drone flight time of 75 minutes. The research results indicate that the highest accuracy value for automatic seed calculation is at a flying height of 50 meters. The success rate of rehabilitation is 1.83% at planting location I and 81,1% at planting location II. The effectiveness of UAV based on processing time is at a flying height of 80 meters. Based on the research findings, efforts are needed from the KTH Bakti Nyata to intensify the maintenance of mangrove seedlings to achieve the rehabilitation program's goals. | en_US |
