Model Spasial Perubahan Kerapatan Mangrove di Kawasan Ekosistem Mangrove Pantai Labu Kabupaten Deli Serdang

Abstract

Research on Spatial Model of Mangrove Density Change in the Pantai Labu Mangrove Ecosystem Area, Deli Serdang Regency using the spatial data model analysis method with remote sensing using Sentinel 2A satellite imagery. Data collection using purposive sampling method and field observations using Canopy Cover Free application analyzing vegetation density data using Line transect method. This research was conducted from October 2023 to February 2024. This research uses mangrove density vegetation analysis, statistical analysis, regression and data validation tests to form a spatial model of mangrove density changes in the Labu Beach Mangrove Ecosystem Area of Deli Serdang Regency in 2016 and 2023 using Sentinel 2A satellite imagery and to determine the density and type of mangroves in the Labu Beach Mangrove Ecosystem Area of Deli Serdang Regency. The results showed that the vegetation density (canopy cover) of the mangrove ecosystem area of Pantai Labu, Deli Serdang Regency in several areas decreased and increased due to various anthropogenic activities and natural activities with a comparison of 2016 and 2023. The percentage change in mangrove density in 2016 and 2023 in the low density class increased by 2,33%, medium density decreased by 9,49%, and high density increased by 7,13%. The findings of mangroves found at the research site consist of true mangroves and mangroves (not true). There are 14 types of true mangroves at the research site, including ; A. ebrateatus, A. ilicifolius, B. gymnorhiza, B. sexangular, C. tagal, R. stylosa, R. apiculata, A. alba, A. lanata, A. corniculatum, S. hydrophylacea, X. granatum, L. racemose, A. speciosum sedangkan jenis mangrove tidak sejati adalah H.tiliaceus. It is expected that the management and rehabilitation policy of mangrove ecosystems in Pantai Labu will prevent the occurrence of various unfavorable impacts in order to remember the importance of the role and physical function of mangrove ecosystems.
