Forests have enormous services for the survival of living things, especially humans. One of the services of forests is to take carbon dioxide (CO2) from the air and replace it with oxygen (O2) needed by other creatures through photosynthesis. Forests are called the lungs of the world, if too much forest is damaged, there won't be enough oxygen to breathe. Climate change is a global phenomenon caused by human actions in the use of fossil fuel energy and land and forestry conversion activities. These activities produce greenhouse gases, especially carbon dioxide (CO2).
As a developing country, Indonesia needs to accelerate the development of industries or transportation with low emission levels through the use of clean and efficient technology and energy utilization. In addition, Indonesia needs to improve the ability of land and forests to absorb greenhouse gases considering that Indonesia is a country that has extensive forest land. Very little research has been done on estimating biomass and carbon content in Peat Swamps. Whereas the estimation of biomass in forests in tropical countries is basically needed because of the potential of large forest biomass in absorbing carbon.
This study aims to analyze the vegetation of plants in Block E on the KPHP Model Tasik Besar Serkap by measuring the volume of trees, calculating the amount of stored biomass, calculating the amount of carbon and stored economic value..
The results of the study have been carried out in 16 Record Units (RU) with a total RU area of 1 Ha (10,000 m2), there are 34 types of vegetation from seedlings, saplings and poles. Species found at seedling, sapling and pole levels recorded in local names are converted into trade names and botanical names. There are 5 types of trees that fall into the category of meranti / commercial group one, namely giam, jelutung, nyatoh, red meranti and white meranti species. For the two types of mixed jungle / commercial wood species there are 8 types of trees including the type of bintangur, guava, mahang, medang, banana, roasted, plump, wood, train and tepis. And the type of ebony tree is included in the category of First Class beautiful wood.
The Importance Value Index (INP) is one of the parameters that can give an idea of the role of the species concerned in the community or at the research location. Based on the analysis of vegetation, it was found that the highest INP was found in Kelat type 57.11%, followed by Suntai type at 35.16% and Meranti at 35.04%, while the lowest INP was found in the Mangosteen Forest type at 1.66%. Based on recapitulation of tree level data, it is known that the total volume of trees of all species is 438.46 m3 with an average volume of 60.75 m3 per species.

Potential of stand biomass at Block E Research Location is 1,354.38 tons / ha. Tree level biomass is influenced by the diameter factor. The diameter of a vegetation has a correlation with its biomass. Plant diameter is affected by photosynthesis results. The process of photosynthesis is the process of absorption of CO2 in the air by plants and converted into carbohydrates (in the form of carbon). Rahayu et.all, (2007) states that the calculation of tree biomass is calculated by the allometric equation. The allometric equation uses a diameter approach. The relationship between diameter and biomass produced is positively correlated.
The amount of stored carbon in the Block E Research Site is 621.84 tons / ha. The amount of stored carbon is obtained from biomass and uses the value of the conversion factor of biomass to carbon stock called the carbon fraction that corresponds to the type / type of forest. The highest amount of stored carbon is found in the Meranti type with a carbon stock of 68.02 tons / ha, Suntai 66.16 tons / ha and kelat 55.24 tons / ha while the lowest amount of stored carbon is found in the Forest Mangosteen type with carbon stock of 1.68 ton / ha.
The economic value of carbon in Block E in the KPHP Model Tasik Besar Serkap is estimated using shadow prices. The carbon price used to estimate the economic value of carbon is obtained by the benefit transfer method. The carbon price used as a reference is the price of carbon trading in Ulu Masen. The price of Ulu Masen carbon is US $ 4 per ton of CO2 emissions that can be prevented (Putro, 2008), assuming an exchange rate of one US $ is Rp.14,010 (Fourteen Thousand Ten Rupiah).
The total carbon content in Block E in the KPHP Model Tasik Besar Serkap is 8,705,760 tons or 621.84 tons / ha. With reference to the Ulu Masen carbon price, the economic value of carbon in Block E in the KPHP Model Tasik Besar Serkap area is US $ 34,823,040.00 or Rp.121,967,697,600.00, while the carbon value in Block E in the KPHP Model Tasik Besar Serkap per hectare is US $ 2,487.36 or Rp. 8,711,978,40. The economic value of carbon in Block E in the KPHP Model Tasik Besar Serkap per hectare area is higher than the economic value of the Gayo Lues forest carbon, which is Rp. 2,552,635.00. (Fauzi et al., 2011).
