Abstract
Ekosistem mangrove berperan penting dalam menjaga stabilitas lingkungan pesisir sebagai pelindung alami terhadap abrasi dan habitat berbagai spesies, termasuk di wilayah Pantai Indah Kapuk (PIK), Jakarta Utara. Namun, tekanan dari aktivitas reklamasi dan ekowisata menimbulkan potensi degradasi lingkungan yang perlu dianalisis secara ilmiah. Penelitian ini bertujuan untuk menganalisis perubahan luasan dan kerapatan mangrove di kawasan Pantai Indah Kapuk periode 2020 hingga 2024 menggunakan citra satelit Sentinel-2A yang diolah melalui Google Earth Engine. Penelitian ini menggunakan metode kuantitatif deskriptif dengan analisis kuantitatif penginderaan jauh untuk mengasilkan data angka yang menggambarkan fakta, karakteristik, dan perubahan objek penelitian secara sistematis. Indeks Vegetasi Normalisasi (NDVI) digunakan untuk mengukur tingkat kerapatan vegetasi, sedangkan klasifikasi tutupan lahan dilakukan menggunakan metode klasifikasi terbimbing (supervised classification) dengan algoritma Random Forest. Validasi akurasi dilakukan melalui confusion matrix dan uji lapangan (ground check). Hasil penelitian menunjukkan selama lima tahun terakhir, luasan mangrove di PIK meningkat dari 336 hektar tahun 2020 menjadi 338 hektar (2021), 354 hektar (2022), 366 hektar (2023), dan 372 hektar (2024) atau bertambah 36 hektar dengan nilai akurasi 93-95%. Nilai NDVI meningkat dari 0,289 (2020) menjadi 0,342 (2024) dengan kategori kerapatan sedang, namun menunjukkan tren positif menuju kerapatan tinggi. Peningkatan ini dipengaruhi program penanaman rutin, keberhasilan bibit hasil program padat karya, tumbuhnya mangrove secara alami di area reklamasi dan tanah timbul. Kesimpulannya, penggunaan citra Sentinel-2A dan Google Earth Engine terbukti efektif dalam memetakan mangrove di PIK. Temuan ini dapat menjadi dasar pengambilan kebijakan bagi pemerintah dan pihak terkait dalam pengelolaan pesisir berkelanjutan serta pelestarian keanekaragaman hayati mangrove di Pantai Indah Kapuk. Mangrove ecosystems play a crucial role in maintaining coastal environmental stability by acting as a natural barrier against abrasion and providing a habitat for diverse species, including in the Pantai Indah Kapuk (PIK) area of North Jakarta. However, pressures from reclamation and ecotourism activities pose a potential for environmental degradation that requires scientific analysis. This study aims to analyze changes in the extent and density of mangroves in the Pantai Indah Kapuk area from 2020 to 2024 using Sentinel-2A satellite imagery processed via Google Earth Engine. A descriptive quantitative method with remote sensing quantitative analysis was employed to generate numerical data that systematically describes the facts, characteristics, and changes of the research subject. The Normalized Difference Vegetation Index (NDVI) was used to measure vegetation density levels, while land cover classification was performed using a supervised classification method with the Random Forest algorithm. Accuracy validation was conducted through a confusion matrix and field surveys (ground checks). The results indicate that over the five-year period, the mangrove area in PIK increased from 336 hectares in 2020 to 338 hectare (2021), 354 hectare (2022), 366 hectare (2023), and 372 hectare (2024), representing a net gain of 36 hectares with an accuracy value of 93-95%. The NDVI value increased from 0.289 (2020) to 0.342 (2024), remaining in the medium-density category but demonstrating a positive trend towards high density. This improvement is attributed to regular planting programs, the success of seedlings from labor-intensive programs, and the natural growth of mangroves in reclamation and newly emerged land areas. In conclusion, the use of Sentinel-2A imagery and Google Earth Engine proved effective for mapping mangroves in PIK. These findings can serve as a basis for policymakers and relevant stakeholders in sustainable coastal management and the conservation of mangrove biodiversity in Pantai Indah Kapuk.
