Abstract

Forests as a producer of environmental services have the potential to reduce carbon dioxide in the atmosphere through photosynthesis. Carbon dioxide exceeded the threshold in the atmosphere can cause the greenhouse effect resulting in global warming is increasing. The research was conducted to find estimation, biomass and carbon forest plants Teak on community forest is in absorbs carbon dioxide (CO 2 ) Developed extensively in Madiun district, and precisely in the village Kare of the sub-District Kare. This research was conducted using sample plots rectangular with an area of 1 ha. Determining the location of the plot is determined by stratified random sampling in areas that have been determined in advance. Results obtained: Estimation of potential stand up for the People's Teak volume on the identity of the community forest village Kare land area of 3154.7 m3. content of Biomass Teak Community forest Village Kare average of 266.80 kg per tree or 50% of average The average weight of the wet conditions. Size Teak Forests People 38.39 Ha as much as 631 stems, the total biomass potential stand Teak is 6462.67 tons. Or when the state average per hectare biomass of 168.35 tons/hectare.Potensi carbon content in biomass conversion method average of 131.31 kg/ tree carbon. With the realization of the plant 24.222 trees or an area of 38.39 hectares, the total potential carbon content is 3,180.71 tons of Carbon. When converted into units of volume per hectare ranges between 84 175 tons of carbon per hectare. The composition of the carbon content of each component of the tree is also different, which is the highest in the stem component, followed by branches, roots, and leaves. The amount of CO 2 sequestration potential Teak Community Forest influenced by the leaf's ability to absorb CO 2 in the photosynthesis process, when converted to the number of plants was 24.222. The tree is about 11 656 tons of CO 2 . Biomass and Carbon content relationship with (DBH) is a model of power with WT = 0.04562.25 for biomass and DBH, CT = 0.0472 DBH 2,233 for carbon.

Abstract

The purpose of this study is the potential Wood and plant biomass potential Jati Unggul Nusantara (JUN). and carbon content (C) stored in various organs of plants, and the potential of plantations to absorb CO2. The study was conducted on private forest in the village Dungus JUN plants. District. Kec. Dagangan . Kab. Madiun, through activities in the forest inventore age of five measurements of wet weight of leaves and twigs, stems, branches and leaves made with the technique of "destructive sampling". Carbon content measurements performed by the indirect method. Potential CO2 uptake was estimated by mass weight conversion. Estimates of potential standing stock ranged Estimated potential for community forest Teak Dungus in the village district. Kec. Dagangan Kab Madiun at age 5 year. The total volume of 53.173 m3 The content of plant biomass ranged JUN of 196.74 kg, reaching 52.90 % of the average weight of the wet conditions. Total biomass potential stand JUN is 121.1 tons. Or when in the state in unit area/Ha, the average biomass of 27.30 ton/Ha. Potential carbon content in biomass conversion method ranged average of 13.65 ton of CO2/Ha. total potential carbon content stand JUN is 46.61 tons of Carbon. When converted into units of v/ha are ranged from 12.45 to 13.65 tons of CO2/Ha. The composition of the carbon content of each component tree is also different, which is the highest in the stem component, followed by branches, roots, and leaves. The amount of CO2 sequestration potential in the conversion of the plant when the plant amount equivalent to 367.17 tons of CO2 overall JUN.

Abstract

Wood is still an important product in forest management activities, therefore the tree volume estimation, measurement of the dimensions of the tree must be done carefully in order to obtain an accurate estimate of the volume of trees that are approaching the estimated volume of the actual volume value. Quality allegations tree volume depends on several factors, including: the level of accuracy desired, tree characteristics, measurement methods, tools used, the current state of the tree dimensional measurement and volume equation used. Estimation of the volume of standing trees research is done in pine plantations (Pinus Jung et de Vriese), in plot 3 a RPH Salam, BKPH North Lawu, KPH Lawu DS, Class VIII KU Forest planting year 1971. Selection of forest class (KU) VIII in this study caused the average grade woods RPH Salam entry into VIII KU and KU logging targets became possible when the time has been unproductive in producing. sap. From the research, the calculation of total sample volume manually tree stand at 171.92 m3 or an average of 2,097 m3 / tree with a minimum volume of 0562 m3 and a maximum of 6.773 m3. Based on the criteria of R2, RSS and SE then elected volume prediction model is Model quadratic equation Y = -1.157 + 2.606 + 15.056 dbh dbh2 .. R2 = 0.996, RSS = 0.1078, SEE = 0107. In calculating the volume using quadratic models shows that the total volume of 82 samples obtained tree volume amounted to 171.87 m3 models or an average of 2,096 m3 / tree. The minimum volume of 0,550 m3 and a maximum of 6.473 m3. Based on t test. test found that t value of 0.053 while t table at 82-1 df = 81 5% (α = 0.05) of 1.615, t (<) is smaller than t table so there is no difference sigifikan / evident between calculations manual volume with the volume calculation using a quadratic models.Keywords: Tree volume, dbh, tree height, form factor, taper function, importance sampling, centroid sampling.
