Abstract

This study examines the effectiveness of mangroves in long distances to the beach in the Mangrove ecotourism area of ​​Pagatan Besar Village. This study aims to determine the effectiveness of mangroves against extreme waves based on wave transformation before and after passing through mangrove vegetation. Data collection methods used are field research, literature and secondary data. The study was conducted by modeling the CMS Wave – SMS structure which predicts changes in height and deflection of extreme waves during the highest tide (Highest Astronomic Tide / HAT) that interacts with mangrove vegetation as a natural beach. The results obtained show that at stations overgrown with mangroves, the waves tend to be still high when approaching the mainland. This is different from Stations 2 and 3 which are overgrown with mangroves. The waves tend to decrease before approaching land. In Profile 1 (not overgrown with mangroves) and Profile 3 (covered with thin mangroves) the wave height is 75 meters from the shoreline (in front of the mangroves) the wave height is 0.31 m and at the back of the mangrove is still 0.01 m on the beach and the back of the mangroves. As for profile 2 (wide mangrove beach) at a distance of 150 m from the shoreline, the wave height has decreased to 0.26 m at the back of the mangrove. The wave height continues to decrease to 0.00 m or has run out.

Abstract

Mangrove is a forest that grows on the coast, generally found in protected estuaries, river banks, and lagoons in subtropical and tropical regions. Mangroves describe ecosystems and plant families that can adapt to an environment influenced by tides. The condition of the mangroves in Bunati Village is quite apprehensive due to the conversion of mangrove land to other land uses such as oil palm plantations, industrial mining excavations, and others, seen from Google Earth images for 2013 and 2022, causing mangrove land cover in Bunati Village to decrease. Therefore it is necessary to analyze changes in land cover and the total area of mangrove damage for ten years from 2012 to 2022 in Bunati Village, Angsana District, Tanah Bumbu Regency, South Kalimantan Province. This study uses Sentinel 2 Satellite Image data for 2022, SPOT 7 for 2017, and SPOT 4 for 2012. The data analysis carried out is overlay. Changes in land cover in 2012 and 2022 in Bunati Village, namely mangrove land remaining to become mangroves covering an area of 73.48 hectares with a percentage of 39.88%, mangroves to non-mangrove 108.99 hectares with a percentage of 59.00%, mangroves to waters 2.05 hectares with a percentage of 1.12%, non-mangrove to mangrove 29.84 hectares with a percentage of 2.81%, non-mangrove to remain non-mangrove 1029.27 hectares with a percentage of 97.02%, non-mangrove to waters 1.79 hectares with a percentage 0.17%, waters turned into mangroves 6.67 hectares with a percentage of 47.14%, waters turned non-mangrove 5.43 hectares with a percentage of 38.35%, and waters turned into waters 2.21 hectares with a percentage of 14.51%. The total area of mangroves that have suffered damage or shrinkage is 74.74 hectares.
