Dinamika Karbon Hutan Alam Dipterokarpa Dataran Rendah Dalam Sistem Silvikultur TPTI Baru di Kalimantan Tengah

Yonky Indrajaya

Abstract


Laju degradasi hutan alam berkontribusi cukup besar terhadap tingginya emisi karbon yang terjadi di Indonesia. Perubahan sistem silvikultur TPTI dengan penurunan daur tebangan dan diameter yang dapat ditebang berpotensi untuk meningkatkan degradasi hutan alam. Penelitian ini bertujuan untuk menganalisis dinamika cadangan karbon yang terjadi pada hutan alam produksi apabila dilakukan kegiatan pembalakan dengan sistem silvikultur Tebang Pilih Tanam Indonesia (TPTI) 2009. Metode yang digunakan dalam penelitian ini adalah matriks transisi. Hasil yang diperoleh dalam penelitian ini adalah: (1) karbon tersimpan dalam biomassa hutan yang dikelola dengan sistem TPTI baru dengan daur 30 tahun lebih rendah dibandingkan karbon tersimpan dalam biomassa hutan yang dikelola dengan sistem TPTI lama dengan daur 36 tahun, dan (2) peningkatan intensitas tebangan menyebabkan perbedaan karbon tersimpan dalam biomassa yang semakin tinggi antara sistem TPTI lama dan baru.
