Pemodelan Emisi Udara Indikator Perubahan Iklim dari Sampah Laut di Kawasan Taman Nasional Laut: Pantai Sombu, Wakatobi
Keywords:
Emisi udara, metode NOOA, perubahan iklim, sampah laut, kawasan lindung lautAbstract
Sampah laut meningkat secara drastis yang sejalan dengan peningkatan populasi, kunjungan wisatawan, dan eksplorasi sumber daya pesisir dan laut. Wilayah taman nasional laut merupakan studi kasus yang sempurna untuk sampah laut karena memiliki ekosistem yang paling rentan. Pantai Sombu merupakan salah satu kawasan perlindungan laut di Taman Nasional Wakatobi (TNW). Metode pengambilan sampel yang digunakan adalah metode garis pantai NOAA dan pemodelan emisi udara menggunakan aplikasi IWM2. Hasil penelitian menunjukkan bahwa konsentrasi rata-rata sampah laut diperkirakan 0,67 unit dan 0,036 kg per m2 dengan komposisi didominasi oleh jenis plastik yaitu 57,71% berdasarkan jumlah dan 48,74% berdasarkan berat. Jumlah dan komposisi sampah laut diperkirakan menghasilkan emisi udara yang berimplikasi pada perubahan iklim sebanyak 52 kgCO2/tahun; 23 kgCH4/tahun; dan 541 kgGWP/tahun.
