Abstract

Desa Sebauk, Kecamatan Bengkalis, menghadapi abrasi dan kebutuhan penanaman kembali pada kawasan mangrove bekas tebang pilih. Kegiatan pengabdian ini bertujuan mendukung konservasi pesisir melalui Program SELARAS (Sebauk Lestari dan Asri) dengan memanfaatkan pemetaan perubahan garis pantai dan estimasi kawasan mangrove. Persiapan dimulai pada Juni 2026, sedangkan pelaksanaan program berlangsung pada Juli–Agustus 2026 dengan sasaran masyarakat dan pemerintah desa. Metode meliputi survei, pemetaan menggunakan ArcGIS, edukasi, pembibitan, penanaman, serta evaluasi deskriptif. Garis pantai didigitasi secara manual dari citra Landsat 8 tahun 2020 dan 2026, sedangkan estimasi kawasan mangrove menggunakan interpretasi citra Sentinel-2A tahun 2026. Hasil pemetaan memperlihatkan segmen abrasi dan akresi serta sebaran mangrove di wilayah pesisir. Kegiatan menghasilkan peta tematik, penanaman 1.300 bibit Rhizophora, dan dokumentasi program melalui website. Pelaksanaan melibatkan 10 mahasiswa bersama pemerintah desa, kelompok masyarakat peduli lingkungan, warga, dan mitra perusahaan. Lokasi penanaman mempertimbangkan riwayat penebangan dan kondisi lapangan, dengan peta sebagai informasi pendukung. Kontribusi program berupa penggabungan informasi spasial dan aksi rehabilitasi partisipatif. Kelompok pemelihara mangrove mendukung tindak lanjut perawatan, sedangkan keberhasilan hidup setelah penanaman masih memerlukan pengukuran berkala.
