Utilization of Landsat Images for Identification and Analysis of Changes in the Mangrove Forest Area in East Aceh District

Abstract

Mangroves are one of the plants that live in coastal areas and have functions and benefits for the surrounding ecosystem. This study aims to examine the accuracy of Landsat 8 OLI's imagery in mapping spatial distribution, analyzing changes in the area, and factors that affect changes in the mangrove forest area in East Aceh District. This study consists of geometric corrections, radians, reflectance, atmosphere, and using the maximum likelihood classification. The results of this study include (1) the level of accuracy of Landsat imagery in mapping the distribution of mangroves in East Aceh Regency was 70.3%, (2) mangroves in East Aceh District experienced a reduction in area of 45099.58 Ha over 22 years, (3) changes are caused by high temperatures of mangrove waters and human activities in utilizing mangroves

Pole Level Mangrove Analysis as a Conservation Effort of the Coastal Mangrove Forest of Langsa City

“…There is a continuous development of coastal areas, especially as a tourist area in the Langsa City Mangrove Forest, it is feared that it will reduce the diversity and areas of mangroves. This occurred in Mangrove Forests in East Aceh District, where observations using OLI Landsat 8 imagery showed that the mangrove area in East Aceh has experienced a significant reduction in 10 years [11]. Coastal development could potentially reduce mangrove diversity in the future.…”
