Kemampuan Tanaman Meranti (Shorea Leprosula) Dalam Menyerap Emisi Karbon (Co2) Di Kawasan Hutan Iuphhk-Ha Pt Itciku Kalimantan Timur

Abstract

The objective of this study was to determine the ability of plantation of Shorea leprosula, which is one species of family Dipterocarpaceae in Borneo, in absorbing carbon dioxide (CO) from 2 the atmosphere. The results of this study are expected to be a reference data on CO emission 2 absorption on the implementation of the program Reducing Emission from Deforestation and Degradation Reduce (REDD) and REDD+ in Indonesia. The study was conducted in IUPHHK-HA PT. ITCIKU Kabupaten Penajam Paser Utara, East Kalimantan. The research was focused on Shorea leprosula stands of 1 to 6 years old with the stem diameter of 2.96 to 8.27 cm with an area of 0.25 ha sampling plot. The results of the study indicated that contribution to absorbing CO from the atmosphere 2 the plantation of Shorea leprosula in IUPHHK-HA PT. ITCIKU ranged from 0.54 to 10.17 tons/ha CO , with average annual CO absorption (average annual growth of C0 , MACO I) from the 2 2 2 2 atmosphere varied from 0.27 to 1.69 tonnes/ha/year. Tujuan penelitian ini adalah untuk mengetahui kemampuan tanaman Shorea leprosula yang merupakan salah satu jenis dari famili Dipterocarpaceae di hutan Kalimantan dalam menyerap emisi karbon (CO) dari atmosfir. Hasil penelitian ini diharapkan dapat menjadi acuan data dalam 2 penghitungan penyerapan emisi karbon dalam pelaksanaan program Reducing Emission from Deforestation and Degradation (REDD) maupun REDD+ di Indonesia. Penelitian ini dilaksanakan di areal IUPHHK-HA PT ITCIKU Kabupaten Penajam Paser Utara, Kalimantan Timur. Objek penelitian difokuskan pada tanaman Shorea leprosula umur 1-6 tahun dan berdiameter batang 2,96-8,27 cm dengan petak ukur sampling seluas 0,25 ha. Hasil penelitian menunjukkan bahwa kontribusi penyerapan CO dari atmosfir oleh 2 tanaman Shorea leprosula di areal IUPHHK-HA PT. ITCIKU berkisar 0,54-10,17 ton/ha CO ,

“…Berdasarkan penelitian (Hardjana & Fajri, 2011) menjelaskan bahwa kemampuan tanaman meranti yang berumur 1 -6 tahun dengan diameter antara 2,96 -8,27 cm dapat menyerap gas karbon dari atmosfer dengan kisaran 0,54 -10,17 ton/ha CO2. Hasil tersebut sejalan dengan potensi tanaman meranti dalam menyimpan cadangan karbon, dimana melalui tahapan fotosintesis, CO2 di udara diserap oleh tanaman dengan bantuan cahaya matahari kemudian diubah menjadi karbohidrat, yang selanjutnya didistribusikan ke seluruh organ tanaman yang ditimbun dalam bentuk biomassa (Rahayu, 2007).…”

A Decrease in Carbon Absorption Potential Due to Timber Harvesting in Natural Forest

“…Many factors affect the absorption of carbon dioxide, which is determined by the amount of magnesium that will give the leaves a dark green color. Hardjana and Fajri (2011) showed the contribution of CO2 absorption from the atmosphere by Shorea leprosula plants in the IUPHHK-HA area of PT. ITCIKU ranged from 0.54 -10.17 ton ha -1 CO2, with an annual average ability to absorb CO2 gas from the atmosphere of 0.27-1.69 ton ha -1 /year.…”

“…If the CO2 absorption volume is reduced, there will certainly be an additional accumulation of CO2 in the atmosphere. Hardjana and Fajri (2011) stated that tree releases carbon into the atmosphere when it is felled. Pukkala (2017) stated that felling had a negative effect on carbon balance for about three decades compared to a no-cutting alternative.…”
