Abstract

Mangrove ecosystems are a crucial component of coastal areas, serving both strategic ecological and economic functions; however, their existence is vulnerable to human activities and the dynamics of coastal environments. The Balikpapan Barat subdistrict is one of the areas in Balikpapan City that features various types of activities, including settlements, industrial activities, and port activities, which have the potential to impact the condition of the mangrove forests. This study aims to analyse changes in the area and density of mangrove forests in 2019 and 2025 using the Normalised Difference Vegetation Index (NDVI) method based on Sentinel-2A satellite imagery. The research method comprises three stages: image pre-processing, NDVI value calculation, and classification of mangrove density into three classes: low, medium, and high. The analysis results indicate a decline in the distribution area of mangroves in West Balikpapan District, primarily due to anthropogenic activities such as infrastructure development, settlement expansion, and coastal industrial activities. However, some areas still exhibit moderate to high vegetation density, indicating the presence of natural regeneration processes and the role of conservation areas in maintaining mangrove ecosystems. This study confirms that the use of remote sensing imagery and the NDVI method is effective in supporting spatial and sustainable mangrove monitoring, and can serve as a basis for planning the management and conservation of mangrove ecosystems in coastal areas.Keywords: mangrove, NDVI, Sentinel-2, Area, Density, West Balikpapan.

Abstract

Rukun tetangga (RT) 035 Kelurahan Karang Joang merupakan kawasan pemukiman yang memiliki potensi untuk berkembang karena berada di lokasi strategis. Fasilitas seperti peta lingkungan yang memuat informasi spasial berupa rumah warga, fasilitas umum, akses jalan, maupun potensi dan resiko lingkungan tidak terdokumentasi dengan baik. Ketiadaan data spasial tersebut dapat menghambat proses berkembangnya RT 035. Pemetaan partisipatif menjadi salah satu solusi dalam mewujudkan kawasan strategis. Pemetaan partisipatif tidak hanya menghasilkan produk peta, tetapi menjadi sarana edukasi, pemberdayaan, dan penguatan ikatan sosial warga dalam membangun kesadaran kolektif terhadap ruang hidup mereka. Pemetaan partisipatif dalam pengabdian ini memiliki 3 tahap. Tahap pertama sosialisasi program pemetaan partisipatif, tahap kedua pelatihan penambahan titik lokasi melalui Google Maps, tahap ketiga yaitu bimbingan teknis kepada warga yang memiliki kendala terkait penambahan titik lokasi. Berdasarkan hasil survei yang diperoleh dari data kuesioner, 92% peserta menyatakan pelatihan mudah dipahami, 88% peserta merasa pelatihan bermanfaat untuk kegiatan sehari-hari, 84% menyatakan siap membantu memperbarui data lokasi, dan 8% peserta masih merasa kesulitan akibat keterbatasan kemampuan perangkat. Berdasarkan hasil survei tersebut, masyarakat antusias dan merasa terbantu dengan adanya sosialisasi pemetaan partisipatif dan penambahan fasilitas peta lingkungan RT 035 Karang Joang.
