Potensi Simpanan Karbon Tanah di Areal Kawasan Hutan Dengan Tujuan Khusus (KHDTK) Haurbentes, Kabupaten Bogor, Jawa Barat

Abstract

Hutan memiliki peranan yang penting dalam menjaga keseimbangan iklim bumi. Keberadaan hutan beserta komponen di dalamnya mampu mengurangi kandungan CO2 di atmosfer. Penelitian ini bertujuan untuk menghitung potensi simpanan karbon tanah pada lahan hutan tanaman Kawasan Hutan dengan Tujuan Khusus (KHDTK) Haurbentes, Kabupaten Bogor, Jawa Barat dan menganalisis hubungan antara kerapatan tegakan serta karakteristik tanah terhadap simpanan karbon tanah. Penelitian dilakukan dengan membuat petak contoh berukuran 20 x 20 m. Analisis contoh tanah untuk mengetahui nilai bobot isi (soil bulk density) dan C-organik dilakukan di Laboratorium Pengaruh Hutan, Fakultas Kehutanan dan Lingkungan IPB. Hasil penelitian menunjukkan nilai bobot isi (soil bulk density) pada jalur penelitian berkisar 0,505 – 0,795 g/cm3. Analisis C-organik tanah pada jalur penelitian berkisar 0,067 - 0,200 %. Simpanan rata-rata karbon tanah pada jalur penelitian memperoleh nilai sebesar 200,217 ton/ha. Hasil uji korelasi menunjukkan bahwa semakin tinggi nilai C-organik dan kerapatan tegakan maka simpanan karbon tanah akan semakin tinggi dan semakin tinggi bobot isi tanah maka simpanan karbon organik tanahnya akan semakin rendah.

Forests have an important role in maintaining the balance of the earth's climate. The existence of forests and their components can reduce the CO2 content in the atmosphere. This study aims to calculate the potential for soil carbon storage in forest plantations in the Special Purpose Forest Area (KHDTK) Haurbentes, Bogor Regency, West Java and analyze the relationship between stand density and soil characteristics on soil carbon storage. The research was conducted by making sample plots measuring 20 x 20 m. Sample analysis to obtain soil bulk density and C-organic values was carried out at the Forest Influence Laboratory, Faculty of Forestry and Enviroment, IPB. The results showed that the soil bulk density at the research site ranged from 0,505 to 0,795 g/cm3. C-organic analysis of the soil at the study site ranged from 0,067 – 0,200 %. The average soil carbon storage at the study site was 200,217 tons/ha. The results of the correlation test showed that the higher the organic C value and stand density, the higher the soil carbon storage and the higher the soil density, the lower the soil carbon organic storage.
