Potensi Kehilangan Cadangan Karbon Akibat Perubahan Fungsi Kawasan Hutan di Kabupaten Mandailing Natal
POTENSI KEHILANGAN CADANGAN KARBON
AKIBAT PERUBAHAN FUNGSI KAWASAN HUTAN
DI KABUPATEN MANDAILING NATAL
ABSTRAK
Penelitian tentang potensi kehilangan cadangan karbon akibat perubahan fungsi
kawasan hutan telah dilakukan di Kabupaten Mandailing Natal. Penelitian
dilaksanakan pada Ijin Pemanfaatan Kayu (IPK) PT. Anugerah Langkat Makmur,
IPK atas nama Subari dan IPK PT. Dinamika Inti Sentosa dimulai dari Bulan
September 2013 sampai dengan Desember 2013. Hasil penelitian menunjukkan
bahwa kawasan hutan di Kabupaten Mandailing Natal berdasarkan perbandingan
antara Tata Guna Hutan Kesepakatan (TGHK) Tahun 1982 dan Keputusan
Menteri Kehutanan No.44/Menhut-II/2005 telah mengalami perubahan luas
fungsi kawasan hutan dimana terjadi penambahan luas terbesar pada Areal
Penggunaan Lain (APL) sebesar 152.503,85 ha serta pengurangan luas terbesar
pada hutan produksi sebesar 121.390,80 ha. Nilai cadangan karbon pohon berkisar
antara 110,16 – 195,56 ton/ha dan cadangan karbon kepala sawit pada umur 1
tahun sampai dengan 5 tahun berkisar antara 2,42 – 9,54 ton/ha. Potensi
kehilangan cadangan karbon terbesar akibat perubahan fungsi kawasan hutan di
Kabupaten Mandailing Natal berdasarkan pemberian Ijin Pemanfaatan Kayu dan
interpretasi peta berturut-turut sebesar 7.458.214,48 ton dan 6.489.729,00 ton.

POTENTIAL LOSS OF CARBON STOCKS DUE THE CHANGES IN
FOREST FUNCTIONS IN MANDAILING NATAL DISTRICT
ABSTRACT
A research on the potential loss of carbon stocks due the changes of forest area’s
function has been conducted in Mandailing Natal District. The research was
conducted at Timber Utilization Permit (TPU) PT. Anugerah Langkat Makmur,
TPU on behalf of Subari and TPU PT. Dinamika Inti Sentosa from September to
December 2013. The result of this research showed that the forest area in
Mandailing Natal District based on a comparison between the Forest Land Use
Agreement of 1982 and the Regulation of Minister of Forestry No.44/MenhutII/2005 has undergone extensive changes in the function of forests where the
addition of the largest area in the distinct forest zone in amount of 152,503.85 ha,
the largest area’s reduction on forest production in amount of 121,390.80 ha.
Tree carbon stock values ranged from 110.16 to 195.56 tons/ha of oil palm and
carbon stocks at the age of 1 year to 5 years ranged from 2,42 to 9,54 tons/ha.
The largest of potential loss on carbon stocks due the changes of forest area’s
function in Mandailing Natal District based on the approval of Timber Utilization
Permit and map interpretation, respectively in amount of 7,458,214.48 tons and
6,489,729.00 tons.
