Abstract

The forestry sector in Indonesia is one of the main sources of greenhouse gases (GHG), given the extensive forests owned Indonesia is one of the largest in the world, along with the high rate of deforestation, forest degradation and degraded land. Forests as one ecosystem dominated by trees vegetation, has the ability to absorb carbondioxide (CO2) from the air and carbon stock in the form of biomass. Indigenous forest Prohibition in the villages Rumbio, Pulau Sarak, Padang Mutung and Koto Tibun is one form of local wisdom that have been implemented long ago by societyof  indigenous forest prohibition Kenegerian Rumbio with the aim of maintaining the existence of the forest. This study aimed to quantify the potential emissions of carbondioxide (CO2) in the area of indigenous forests prohibition Kenegerian Rumbio. Potential emissions of CO2 in the soil surface at indigenous forests prohibition Kenegerian Rumbiois 1824.15 t/ha/yr. Overall potential emissionsof CO2in the soil surfaceat indigenous forests prohibition Kenegerian Rumbio is 966,799.5 t/y. Sparse vegetation density of CO2 emissions from the soil surface was higher (125.48 t/ha/yr) then moderate vegetation (84.50 t/ha/yr) and dense vegetation (61.10 t/ha/yr). Differences related CO2 emissions released by the micro-climate conditions such as air temperature and soil temperature, as well as the rate of CO2 emissions from the soil surface in each type of vegetation density.Keywords:  Emissions, Carbondioxside (CO2), Rumbio, Kampar

Abstract

Elephants are large mammals that live in Indonesia especially in Sumatra Island usually called Sumatran Elephants. Population of Sumatran Elephants continues to decrease because the habitat in natural forests is shrinking. One of causes about decline the population because land contriction. Damage and descent in area Sumatran Elephant habitat will have an impact on the availability of elephant feed. This reason can result in the transfer of roaming areas and shifting the elephant's habitat. This study aims to determine the characteristics of elephant habitat in the Tesso Nilo National Park and its surroundings. The study was used the method purposive sampling by determined the habitat characteristics of Sumatran elephants. Characteristics of elephant habitat in TNTN and surrounding areas are four types of vegetation, namely canopy closure in natural forests 31.25-68.59%, shrubs 0%, acacia stands 35.77-58.83%, oil palm plantations 50.98-64.76%. Availability of feed plants in in natural forests 22.22-62.96%, shrubs 8.11-94.44%, acacia stands 42.11-80.77%, oil palm plantations 0-90.79% and the availability of body scrub trees was only found in natural forests, that is 8 trees while other locations are not found. Characteristics of elephant habitatin natural forests, shrubs, acacia stands, oil palm plantations including lowland and has a flat topography. The distance from natural forest to scrub is 4-291 m, acacia stands 4.750-5.270 m, oil palm plantations2.580-2.900 m. The distance to water sources from natural forests is 3-218 m, bushes 4-198 m, acacia stands 348-525 m, oil palm plantations 535-811 m. Keywords:Elephant, location, characteristic, habitat
