Salah satu komoditas pertanian yang memberikan andil dalam penyerapan dan emisi CO2 adalah tanaman karet.Tulisan ini bertujuan untuk menghitung jumlah karbon yang diemisikan dan diserap (Carbon Footprint/CF) dalam proses budidaya tanaman karet mulai dari pembibitan, persiapan lahan, penanaman, dan pemeliharaan sampai tanaman diremajakan. Jumlah karbon yang diserap oleh tanaman karet diperoleh berdasarkan analisa C-organik sampel bibit tanaman karet baik yang masih berupa batang bawah, bibit polibeg dua payung dan tanaman karet klon GT1 pada saat diremajakan. Jumlah karbon yang diemisikan dihitung dari proses pembuatan bibit polibeg dua payung daun sampai tanaman diremajakan. Total emisi karbon yang dihasilkan mulai dari proses pembuatan bibit sampai peremajaan karet tua adalah 728,87 kg CO2-e/tanaman. Sebaliknya total serapan karbon oleh tanaman karet selama satu siklus adalah 2.278,17 kg CO2-e/tanaman untuk klon GT 1. Klon GT1 dalam satu siklus dapat menghasilkan 68,55 kg karet kering/tanaman, sehingga untuk memproduksi 1 kg karet kering telah diserap 33,23 kg CO2 dan diemisikan 10,63 kg CO2. Selain itu, untuk menghasilkan 1 kg produk karet remah, karet sit, atau lateks pekat, akan dihasilkan emisi karbon tambahan sebesar 0,313; 0,126; dan 0,151 kg CO2-eq/kg produk yang dihasilkan berturut-turut. Karena itu, apabila dihitung mulai dari proses pembibitan tanaman karet, telah diserap karbon sebanyak 33,23 kg CO2 dan diemisikan karbon sebanyak 10,94; 10,75; dan 10,78 kg CO2-e untuk setiap kg karet remah, karet sit, dan lateks pekat yang dihasilkan berturut-turut. Hal ini menunjukkan budidaya tanaman karet memberikan andil positif dalam penyerapan karbon dari atmosfer dan menekan pemanasan global.References
