Bentang alam pesisir di Gampong Kajhu telah mengalami transformasi lanskap berupa perubahan struktur ruang secara masif dan dinamika perubahan lahan pascabencana Tsunami 2004. Fenomena yang terjadi mengalami proses evolusi dan berdampak pada fungsi ekologi masyarakat lokal. Tingkat kehancuran ekstrem di Gampong Kajhu mencapai 85% korban jiwa dari total populasi, dan menyisakan 15% penduduk sebagai penyintas yang mengungsi ke wilayah Zona Evakuasi (BRR Aceh dan Nias, 2009). Tujuan penelitian untuk menganalisis implikasi transformasi perubahan Penggunaan dan Tutupan Lahan (PTL) terhadap Nilai Jasa Ekosistem (NJE) dan kondisi Sosio-Ekonomi tahun 2015-2025. Jenis penelitian menggunakan mixed methods dengan desain studi kasus integrasi potensi kearifan lokal dan modal sosial sebagai upaya mitigasi bencana. Data citra satelit beresolusi tinggi diperoleh dari Google Earth Pro menggunakan Landsat 8 dan Sentinel 2A melalui teknik Supervised Image Classification dan Sensitivity Analysis Spasial. Validasi data dilakukan melalui Stratified Random Sampling dengan hasil Overall Accuracy 95,2% dan Kappa Coefficient 0,951. Model Summary (R-Square) yaitu R2 = 0,711 dan R = 0,843. Metode Contingent Valuation Method (CVM) yang melibatkan 195 rumah tangga. Identifikasi kelas lahan mengungkapkan dinamika perubahan vegetasi dan mangrove seluas 66,12 hektar yang berdampak pada kerugian ekologis senilai Rp290 miliar per tahun, kerusakan biofisik menyebabkan eskalasi debit banjir sebesar +23,61 m³/s yang mengancam 33% area hunian penduduk. Rekomendasi penelitian yaitu implementasi kebijakan moratorium RTRW dan RDTR pada zona kritis, revitalisasi instrumen kearifan lokal dan pengelolaan dana Willingness to Pay (WTP) secara real-time melalui monitoring partisipasi untuk menjamin restorasi pesisir yang tangguh dan berkelanjutan tanpa mengabaikan kelestarian modal alam.

The coastal landscape of Kajhu Village has undergone a profound structural transformation following the catastrophic 2004 Indian Ocean Tsunami. This study examines the evolutionary trajectory of Land Use and Land Cover (LULC) changes between 2015 and 2025 and their multifaceted implications for Ecosystem Service Values (ESV) and socio-economic dynamics. Employing a transdisciplinary mixed-methods approach, this research integrates high-resolution satellite imagery (Landsat 8 and Sentinel-2A) with a case study design that embeds local wisdom and social capital into disaster mitigation frameworks. LULC dynamics were analyzed using Supervised Image Classification and Spatial Sensitivity Analysis, validated through Stratified Random Sampling, yielding an Overall Accuracy of 95.2% and a Kappa Coefficient of 0.951. Statistical modeling (R² = 0.711; R = 0.843) confirms a significant correlation between land conversion and ecological degradation. Findings reveal a critical loss of 66.12 hectares of vegetation and mangroves, resulting in an estimated ecological deficit of IDR 290 billion per annum. Biophysical damage has triggered a flood discharge escalation of +23.61 m³/s, threatening 33% of residential areas. Socio-economic assessment via the Contingent Valuation Method (CVM) involving 195 households highlights a pragmatic community stance toward environmental loss. This research recommends the implementation of a moratorium policy on Spatial Plans (RTRW) and Detailed Spatial Plans (RDTR) within critical zones, complemented by the revitalization of indigenous wisdom as a governance instrument. Furthermore, it proposes a real-time management system for Willingness to Pay (WTP) funds through participatory monitoring. This integrated approach aims to ensure resilient and sustainable coastal restoration while safeguarding the integrity of natural capital.
