Biological invasions are a major threat to biodiversity worldwide. Here, we aim to assess the occurrence of two invasive Asteraceae, Austroeupatorium inulifolium and Ageratina riparia, and the extent of their distributional range along altitudinal gradients in Mt Pohen, Batukahu Nature Reserve, Bedugul, Bali. The cover abundance of Austroeupatorium inulifolium and Ageratina riparia were measured by establishing 92 plot samples in four different forest conditions encompassed elevational ranges from the lowest (forest borders) to the highest elevation of Mt Pohen. Results showed that the abundance of both Asteraceae invaders were strongly correlated with disturbed habitats located at lower elevation. The forest borders at these forest sites were characterized by dense thicket of Austroeupatorium inulifolium and high abundance of Ageratina riparia. Both Asteraceae invaders reach their maximum altitudinal range up to the highest peak of the Mt Pohen. Results highlight that high abundance of these Asteraceae invaders which forms dense cover may lead to major forces of change in plant communities and forest ecosystem.

Research of bioaccumulation of Pb and Cr in vertical biofiltration systems with bacterial inoculum derived from aquatic sediments South Denpasar aims to get the best sediment sources that can be used as an active suspension to process metals Pb and Cr dissolved. Sediment samples taken from some waters are ecosystems Mangrove Statue Ngurah Rai Tuban, Benoa Harbour and Estuary Dam Suwung. Each sediment samples were grown in a liquid medium to get the best active suspension, which was determined by an increase in biomass ( VSS ) and the speed of growth. Best active suspension is used as inoculum in the vertical biofilters to decreaseconcentration of Pb and Cr dissolved. Ability of vertical biofilter is determined by their effectiveness in lowering levels of Pb and Cr and capacity of the system used. The results showed that the vertical biofiltration system capable of lowering the concentration of Pb and Cr to each concentration became 0.1680 ppm and 0.1460 ppm within 6 hours of treatment with initial concentration of 2 ppm respectively. The results showed that the vertical biofiltration system capable of decreasing the concentration of Pb and Cr became 0.1680 ppm and 0.1460 ppm within 6 hours of treatment with initial concentration of 2 ppm respectively. This concentration has been below the qualitystandard (PerGub Bali No.8 Tahun 2007). The highest effectiveness of vertical biofilters system against Pb and Cr occurred while processing time of 24 hours with the respective value amounted to 99.49 % and 99.41 %. While the value of biofiltration capacity in lowering the concentration of Pb and Cr amounting 4,3188x10-3 mg/g and 4,5369x10-3 mg/g. In microbiological tests, one type of bacteria that play a role in the process of bioaccumulation of Pb and Cr is Bacillus sp in the amount of 20 CFU/g.

Land resource damage caused by the land conversion and land use without regard to principles of conservation of soil and water. The damage resulted in the erosion is very high. Changes in land use without regard to principles of conservation of soil and water is currently happening in Baturiti District. Given this research can determine the level of erosion, soil and water conservation planning, land capability classification and proposed land use in Baturiti District. Erosion prediction using USLE (Universal Soil Loss Equation) to estimate the rate of erosion and also to get an idea the determination of soil and water conservation measures appropriate to the region. Determination of the land capability classification method Arsyad (1989) is by classifying land capability to classify land capability class based on the value of the limiting factor of land that is adjusted with land capability classification criteria. Determining of the proposed land use using the scoring method by combining the slope factor of the field, the soil sensitivity of the against erosion and the intensity of daily rainfall. Soil sampling is done by taking a total of 19 soil samples from a unit of land. The prediction results on each unit of land erosion in the area showed the level of erosion is very light covering an area of 11,70 ha, mild erosion area of 5.221,56 ha, erosion was an area of 88,10 ha, severe erosion area of 616.20 ha and very severe erosion area of 2.195,39 ha. Soil and water conservation measures required on land units with erosion prediction value exceeds the value erosion that can be tolerated so that the value could be below the value erosion erosion can be tolerated. Capability classification of the land in the study area consists of land capability class II with an area of 1489,39 ha, class III area of 827,39 ha, class IV with an area of 830.15 ha, class VI area of 1.373,79 ha, class VII covering 1.453,92 ha, class VIII covering an area of 2.176,31 ha. Tutorial use of land for the forest department is directed to the protected forest area covering an area of 2.458,00 ha. Tutorial use of land outside the forest area to protected area 1079.81 ha (13,27%), a buffer zone covering an area of 1.662,31 ha, annual crop cultivation area covering an area of 844.86 ha and seasonal crops cultivation area covering an area of 2.087,97 ha.
