Abstract

The rate of change in forest area into plantations tend to be greatly improved from year to year. As a result of forest land will be increasingly threatened its existence as it is converted to plantations. For that to know how the ratio of the absorption of CO2 by growers compared with forests. The purpose of this research were to know the carbon content in each section rubber tree (Hevea brasiliensis Muell. Arg.) and to determine the potential of carbon reserves in the rubber tree (Hevea brasiliensis Muell. Arg.) age of 10 years in people plantation Serdang Bedagai. The method of estimaty carbon stocks  had done destructive ends. Selection of plant samples carried out with purposive sampling. The best equation for estimating biomass and carbon selected using allometric equations based on the value of the highest R-Sq and practicality aspect. The results showed that allometric models for biomass and carbon wasW=3.42 DBH1.153 and  C = 0.58 DBH 1,586 respectively. The potential of biomass and carbon in smallholder rubber plantations Tarean Village, District Silindak, Serdang Bedagai were 40.54 tons / ha and 20.58 tons C/ ha ,respectively. Keywords: rubber, Carbon stocks, biomass, allometric models

Abstract

Global warming is causing an increase in temperature of the earth's atmosphere, climate change, resulting in the dry season and rising temperatures. Efforts to control global warming is with the plant the absorption of carbon. One of which is rubber plant that has a high potential carbon reserve. The purpose of this research want to know the carbon content in each section rubber tree (Hevea brasiliensis Muell. Arg.) and determine the potential of carbon reserves in the rubber tree (Hevea brasiliensis Muell. Arg.) Age of 5 years in people plantation Serdang Bedagai. The method of estimaty carbon stocks done destructive and selection of plant samples carried out with purposive sampling. The carbon content in each section rubber trees (Hevea brasiliensis Muell. Arg.) 5 years of age is different is stem 50.37%, 40.58% branches and leaves 21.68%. The results showed that allometric models for biomass and carbon has W = 3.425 DBH1.153 and C = 0.582 DBH 1.586 , respectively. The potential of biomass and carbon in smallholder rubber plantations Tarean Village, District Silindak, Serdang Bedagai were 2.71 tons / ha and 1.18 tons C / ha, respectively. Keywords: Karet (Hevea brasiliensis Muell. Arg), carbon stocks, biomass measurement, allometric models.

Abstract

The purpose of this study were to determine the potential of carbon on under storey level and to determine the effect of slope on a large or small carbon stocks in understorey in education forest University of North Sumatera District Karo. The research was conducted in April 2015. Data was collected by using purposive sampling with random start. Plot size is 20m x 20m as 6 plots with 3 plots in area ramps and 3 plots in steep terrain. Data were collected by destructive methods. The results showed that 14 species are found under the ramps region and 12 species on the steep region. Potential carbon found in the ramps region that is equal to       93,08 kg/ha and the potential of the carbon contained in the steep region that is equal to 83,84 kg/ha. The carbon in the ramps region is larger than in the steep region. Keywords: carbon, understorey, ramps region, steep region, education forest University of North Sumatera
