Abstract

Pemanasan global yang terjadi di permukaan bumi merupakan akibat dari peningkatan suhu atmosfer bumi sebagai akibat intensitas dari penggunaan bahan bakar fosil, penebangan pohon dan perusakan pohon yang sudah tidak terkendali lagi. Penelitian ini bertujuan untuk mengetahui karakter pertumbuhan tanaman karet (Hevea brasiliensis) dan potensi timbunan carbon pada tegakan karet (Hevea brasiliensis.) HGU PT Bakrie Sumatera Plantation Tbk. Metode penelitian yang digunakan dalam penelitian ini adalah metode inventarisasi potensi kayu dengan mengukur diameter, tinggi bebas cabang dan volume kayu. Pengolahan data potensi Carbon dilakukan dengan menggunakan rumus allometric yang digunakan oleh Lubis A.R (2011), Chave et al (2005) dan Khairiah et al (2011). Hasil penelitian menunjukkan bahwa diameter batang pohon karet rata-rata berumur 5 tahun, 10 tahun, 15 tahun dan 20 tahun berturut-turut adalah 15 cm, 18 cm, 22 cm dan 30 cm. Tinggi pohon bebas cabang kayu karet rata-rata berumur 5 tahun, 10 tahun, 15 tahun dan 20 tahun berturut-turut adalah 2,43 m, 4,22 m, 7,08 dan 10,61m. Sedangkan volume kayu pohon karet rata-rata berumur 5 tahun, 10 tahun, 15 tahun dan 20 tahun berturut-turut adalah 9,0955 m3/ha, 21,1723 m3/ha, 57,4295 m3/ha dan 163,5759 m3/ha. Berdasarkan hasil penelitian ini maka dapat disimpulkan bahwa potensi Carbon kawasan HGU Bakrie Sumatera Plantation Aek Salabat Kabupaten Asahan menurut perhitungan rumus Lubis, AR adalah 2,0513 ton/ ha, menurut rumus Chave adalah 3,4290 ton/ ha, menurut perhitungan rumus Khairiah adalah 4,1150 ton/ ha serta potensi Carbon rata-rata dari ketiga rumus tersebut adalah 3,2118 ton/ ha.

RETRACTED: Pengaruh jumlah pohon, produktivitas dan upah pekerja penyadapan getah pinus terhadap penerimaan negara di Kabupaten SimalungunSihombing, B. H., & Purba, T. (2023). Pengaruh jumlah pohon, produktivitas dan upah pekerja penyadapan getah pinus terhadap penerimaan negara di Kabupaten Simalungun. Jppi (Jurnal Penelitian Pendidikan Indonesia), 9(4), 205-214.Based on the author's request to change the affiliation from Universitas Lancang Kuning to Universitas Simalungun, made on September 6, 2024, this is not permissible as the journal has already been published for one year, and the author is only now requesting the change.The norm is to list the institution where the work was conducted and to indicate the new corresponding address or email in a footnote (or if there is already a footnote, the new affiliation/contact should immediately follow). It appears that minimal work (if any) was conducted at the new institution, so the affiliation should reflect where the work was originally done. Politically, the new institution may want to claim the new publication, and the author might want to assist with this. However, since the work was completed at the prior institution on their salary, the resulting article should maintain that affiliation, with a note providing the author’s new address.
