Judul: Pendugaan Potensi Karbon pada Tegakan Pinus (Pinus merkusii Jungh et de Vriese) Di KPH Sukabumi, PERHUTANI Unit III, Jawa Barat dan Banten
Abstrak: Penelitian ini bertujuan untuk mengetahui kadar karbon (C) pada berbagai bagian pohon dan menduga potensi karbon dalam tegakan Pinus (Pinus merkusii Jungh et de Vriese). Pemilihan pohon contoh pada setiap kelas diameter dilakukan secara purposif sampling. Pendugaan potensi karbon dilakukan pada bagian pohon yaitu akar, batang, cabang, ranting dan daun serta seluruh bagian pohon. Kemudian dilakukan pengujian bahan contoh di laboratorium untuk mengetahui kadar karbon pada setiap bagian pohon. Persentase karbon pada bagian-bagian pohon Pinus (Pinus merkusii Jungh et de Vriese ) yang paling tinggi terdapat pada batang sebesar 46,63% yang paling rendah terdapat pada daun sebesar 31,12%, secara keseluruhan rata-rata kadar karbon pohon pinus adalah 41,51%. Hasil uji nyata menunjukkan sebagian besar kadar karbon dalam biomassa masing-masing bagian pohon pinus (Pinus merkusii Jungh et de Vriese) berbeda nyata, kecuali pada uji bagian batang terhadap ranting. Model persamaan pendugaan massa karbon pohon yang terpilih adalah sebagai berikut akar adalah C = 0.002692 D2.80, batang adalah C = 0.011749 D2.84, cabang C = 0.001549 D2.81, ranting adalah C =0.001023 D2.79, daun adalah C = 0.000708 D2.80 , dan massa karbon pohon adalah C = 0.017783 D2.83. Potensi massa karbon pada tegakan pinus (Pinus merkusii Jungh et de Vriese) di KPH Sukabumi, Perhutani Unit III, Jawa Barat dan Banten adalah sebagai berikut pada kelas umur I sebesar 132.928,12 ton C, kelas umur II sebesar 126.365,26 ton C, kelas umur III sebesar 150.356,35 ton C, kelas umur IV sebesar 96.921,84 ton C, kelas umur V sebesar 177.212,05 ton C, dan kelas umur ≥VI sebesar 184.018,21 ton C.

Abstrak: Global warming is one of the major environmental issues that currently concern to the various parties. Because of global warming, increasing in average temperature of earth's sea and land caused by industrial activity and reduction of forest cover due to deforestation, especially lately. Based on these evolving issues and considering the importance of the role of forests in absorbing carbon from the air and store it in forest biomass, it is necessary a lot of research that could encourage the continued development of carbon in biomass. One important aspect of research is to know the potential of carbon stored in the stands of pine. The experiment was conducted in KPH Cianjur, Perum Perhutani Unit III West Java and Banten in April 2010 to May 2010. Materials used in this research were planting stands of pine in 1994 on square 27A RPH West Hanjawar BKPH South Sukanagara and planted stands of Pine year 1995 on square 48I RPH East Hanjawar BKPH North Sukanagara in KPH Cianjur, Perum Perhutani Unit III West Java and Banten. The tools used in this study include scales, digital scales, ovens, machete, newsprint, chalk, plastic bags, plastic rope, stationery, tally sheets, calculator, tape measure, camera, and software SAS. In the area of stands are made each 5 plots with a size of 20 m x 20 m to measure the trees and also made small plots measuring 2 m x 2 m by 4 pieces located at each corner for analysis and retrieval of vegetation and litter. Results obtained from these data are processed through the approach of biomass which is then converted to carbon savings in ton/ha. To know the factors that influence the use of carbon deposits by using ANOVA analysis and Duncan Multiple Range Test (DMRT). The results showed that the potential of carbon storage on plots planted in 1995 is 77,1580 ton/ha greater than the potential carbon storage on plots planted in 1994 which only amounted to 64,6372 ton/ha. The test results using ANOVA statistical analysis showed the value of R-Sq = 96,01% and significant level 5%, there is a difference between the carbon potential on one of the object variabel (tree, manure, below plant) which is found on the stands of pine planted in 1994 and stands pine planting in 1995, where the variable is a tree. There needs to be further research on the estimation of carbon stock potential using a different method of harvesting method with the same kind of pine stands.
