Abstract

The mangrove ecosystem in Indonesia faces complex anthropogenic pressures threatening its sustainability. This study analyzes the land cover dynamics of mangroves in Labuhan Maringgai Subdistrict, East Lampung Regency, over the period 20142024 using Landsat 8 satellite imagery and the Support Vector Machine (SVM) method with accuracy exceeding 88%. The results reveal a significant conservation paradox: mangrove area increased by 415.35 hectares (53%) from 783.81 to 1,199.16 hectares, yet only 43.98% of the original mangrove cover remains intact. Natural regeneration predominates in former shrimp ponds and open lands, while the largest conversion occurred into shrimp ponds (11.02%) and mixed gardens (7.45%). Human activities demonstrate dual impacts: continued pressure from land conversion and exploitation, but a decline in shrimp pond activity due to coastal abrasion has stimulated natural recovery. A critical finding is the mortality of Avicennia sp. mangroves caused by permanent inundation, indicating that global pressures such as sea-level rise exacerbate local impacts. Despite quantitative increase, habitat fragmentation and ecosystem quality decline highlight long-term vulnerability. This study contributes to the understanding of coastal mangrove dynamics in Indonesia and recommends an integrative management approach combining conservation with sustainable economic development to build resilience in coastal ecosystems. Keywords: Mangrove; Land Cover Dynamics; Support Vector Machine; Landsat 8; Labuhan Maringgai.
