Pertumbuhan dan Serapan Karbon Tanaman Silvikultur Intensif Shorea parvifolia Pola Rumpang (Kasus di PT Sarpatim, Kalimantan Tengah)
Abstract
SILIN pola rumpang dianggap dapat mempercepat produktivitas hutan alam. SILIN dapat berperan dalam meningkatkan serapan karbon dan dapat dimasukkan ke dalam mekanisme perdagangan karbon di sektor kehutanan. Penelitian ini bertujuan menganalisis pertumbuhan dan kemampuan serapan karbon tanaman SILIN S. parvifolia pola rumpang. Sebanyak 30 plot contoh tanaman SILIN berbagai umur dan kemiringan lapangan diukur untuk mengetahui pertumbuhan dan kemampuan serapan
karbon. Pertumbuhan rata-rata riap diameter dan tinggi tanaman sampai umur 5 tahun masing-masing 1,66 cm/tahun dan 1,41 m/tahun. Persen hidup tanaman di kelas umur 4-5 tahun mencapai 89%. Kemiringan lapangan tidak memberikan pengaruh berbeda
terhadap pertumbuhan riap diameter dan tinggi tanaman SILIN. Cadangan karbon tanaman SILIN pola rumpang di kelas umur 4-5 tahun sebesar 5,98 ton C/ha dengan serapan karbon sebesar 4,78 ton CO2/ha/tahun. Terdapat hubungan serapan karbon (CO2??????????, ton CO2/ha) terhadap umur (A, tahun) yang dirumuskan dengan persamaan CO2 stocks = e^(6,829-17,181/A) (lack of fit = 0,128 dan s = 2,263). Cadangan karbon
tegakan alam areal SILIN pola rumpang sebesar 42,74 ton C/ha terdiri atas pohon hidup, pohon mati berdiri, pohon mati rebah, dan serasah. SILIN by gap pattern is considered to accelerate the productivity of natural forests. SILIN can play a role in increasing carbon sequestration and can be included
in the carbon trading mechanisms in the forestry sector. This research aims to analyze the growth and carbon sequestration of the SILIN S. parvifolia in the gap pattern. As many as 30 sample plots of SILIN plants at various ages and slopes were measured to determine growth and carbon sequestration capacity. The average increment in diameter and height of the plants up to 5 years of age is 1,66 cm/year and 1,41 m/year.
The survival rate of plants in the 4-5 years age class reached 89%. The slope doesn’t have a significant effect on the increment growth of diameter and height. The carbon stock of SILIN plants in the 4-5 years age class is 5.98 tons C/ha, with carbon sequestration of 4,78 tons CO2/ha/year. There is a relationship between carbon
sequestration (CO2 stock, tons CO2/ha) and age (A, years) expressed by the equation CO2
stocks = e^(6,829-17,181/A) (lack of fit = 0,128 and s = 2,263). The carbon stock of the SILIN gap pattern includes natural trees, standing dead trees, fallen dead trees, and
litter, resulting in an average total carbon stock of 42.74 tons C/ha.
