Abstract

As an effort to reduce greenhouse gas emissions, then amount of CO2 in the air must be controlled by increasing the amount of CO2 absorption by plants as much as possible and supress CO2 emissions into the air as low as possible.  This research was conducted in order to obtain information about the amount of carbon stored in Imperata cylindrica which grows in dry land areas. Sampling method is done by purposive in consideration with the distribution of this plant group.  Measurement of carbon stored includes the measurement of biomass, organic carbon measurement on I. cylindrica and measurements of carbon stored. The data obtained are analysed statistically and analysed with the parametric one way ANOVA. The results obtained that the carbon stored in I. cylindrica on dry land of Cempaka District consecutive 67.55 g.m-2, 116.25 g.m-2, and 96.63 g.m-2

Abstract

This study aims to determine the structure of phytoplankton communities in the pool are former coal mining Desa Kampung Baru Kecamatan Cempaka which include abundance, diversity, uniformity and dominance. Phytoplankton samples taken in two pools with a purposive sampling method with a three-point shooting at each pond. Sampling was performed three times. Phylum of phytoplankton were identified in both pools as much as 2 phylum (Chloropyta and Chrysopita) with 17 genera. Average abundance of phytoplankton in the first pool of 7174 ind / liter and 6873 ind / liter in the second pool. The average diversity index of phytoplankton in the first pool of 1.540 and 1.621 in the second pool. Average uniformity index of phytoplankton in the first pool of 0622 and 0.623 in the second pool. The average index of phytoplankton dominance in the first pool of 0271 and 0250 in the second pool. Analysis of community structure (abundance, diversity, uniformity and dominance) shows the condition of the two ponds in the state is quite stable and capable of supporting life inside the phytoplankton. Where the pool in the fertility rate is the level of contamination is, the conditions included in the category of individuals spread more evenly and there are no species that dominate other species in the extreme.
