Abstract

Jumlah cadangan karbon dapat diketahui berdasarkan nilai biomassa hutan yang ada didalamnya sehingga diperlukan informasi alokasi biomasa setiap bagian pohon agar membantu program pemantauan cadangan karbon hutan, diantaranya informasi biomassa atas permukaan. Biomassa atas permukaan memiliki kontribusi paling besar dari biomassa total, hal ini menunjukkan bahwa pertumbuhan usia suatu pohon memiliki pengaruh terhadap nilai biomassa yang dihasilkan. Perhitungan nilai biomassa yang akurat hanya dilakukan dengan metode destruktif atau non-destruktif sehingga membutuhkan waktu yang lama untuk menghitung nilai biomassa dalam cakupan yang luas sehingga penggunaan metode penginderaan jauh dan pemodelan merupakan langkah yang tepat. Penelitian ini bertujuan untuk memprediksi nilai biomassa atas permukaan (Above Ground Biomass atau AGB) pohon karet berdasarkan usia tegakan pohon menggunakan metode Multivariate Linear Regression (MLR). Berdasarkan hasil pengolahan bahwa usia memiliki hubungan dengan nilai biomassa atas permukaan ditunjukkan nilai R² = 0,694. Hasil pemodelan antara backscatter VH dan VV Sentinel-1A dengan biomassa lapangan didapatkan persamaan Y= 20,034*VH + 15,308*VV + 523,305 (R²=0,592). Hasil total prediksi nilai biomassa atas permukaan kebun karet Afdelling Setro sebesar 84.158,840 ton dengan luas 702 ha.
