Abstract

Currently the construction of reclamation in Jakarta Bay being carried out on several islands that have been approved by the Government of Indonesia and located nearby the Mangroves forests ecosystem which always inundated by seawater and are affected by tides.  The purpose of this study were analyzing the changes in the mangrove ecosystem area due to the changes in Total Suspended Solid (TSS) based sedimentation and the effect of hydro-oceanography factors on the TSS. This research was conducted using a literature study, processing the LANDSAT OLI images for the analysis of mangrove changes, TSS analysis, and analysis of the effect of hydro-oceanography on TSS within the years of 2013 to 2020. The results of this study indicate that the area of mangrove forest on the coast of North Jakarta is enlarging by 3-5 ha/year, especially in the reclamation island area due to the process of sedimentation which is influenced by hydrooceanography. High sedimentation can be shown from the high value of Total Suspended Solid (TSS) in the waters. The TSS values processed by the satellites images also showed a significant increase during these years between 2013 to 2020 except December 2018 experienced the lowest value. While the hydro-oceanographic factor has lesser effect on the TSS value compare to mangrove ecosystem in the study area.

Abstract

Mangrove ecosystems are important for maintaining ecological balance in coastal areas. To monitor changes in mangrove area and density, remote sensing technology with Landsat 8 and NDVI Index was used. The research focuses on the North Coast of East Java, from 2019-2024, on the coast of Surabaya, Sidoarjo, Pasuruan, Probolinggo, and Situbondo. The purpose of this study is to analyze changes in mangrove area and density. The survey method was conducted with Landsat 8 images and in situ data in 2024. There are 5 observation station points with the determination of station points using purposive sampling technique. Accuracy test using RMSE. The area of mangroves on the coast of Surabaya, Sidoarjo and Pasuruan from 2019 to 2024 ranged from 1611.88 ha-2270.41 ha. The highest cover area was in 2024 and the lowest in 2019. Mangroves with sparse NDVI category ranged from 46640.61 ha-53284.95 ha. Moderate NDVI ranged from 4313.25 ha-6984.72 ha and dense NDVI ranged from 493.29 ha-4711.5 ha. The area of mangroves on the coast of Probolinggo and Situbondo increased from 2019-2024, which amounted to 1487.05 ha-1885.79 ha. Mangroves with sparse NDVI category have an area between 51367.12 ha-54852.64 ha. Moderate NDVI ranged from 5564.87 ha-54852.64 ha and high NDVI ranged from 668.18 ha-1585.52 ha. The results show that there are changes in the area and density of mangroves on the north coast of East Java every year. These changes need to be monitored annually to address the decline in mangrove area and density quickly and appropriately.
