The aim of the study was to know the population condition in savannah invaded by plant of Melaleuca sp and Eucalyptus sp specially disavan of mixture Ud-Udi. Useful research as reference data in nimble population walabi management in Wasur National Park. Method used of strip transect and plot the swampy forest animal. Perception conducted at three band that is band ecoton, savana band which abut the ecoton and band of mixture savana. This research is executed by during one month that is from april until may 2008. From result invetarisation obtained by that average of density the nimble walabi at Udi-Udi mixture savana is 0,67 tail per hectare. Highest density that is at band ecoton with the density 1,67 tail per hectare. From this result is known that by the nimble walabi prefer to be at the band ecoton compared to by band of mixture savannah which abut the forest of mixture and band of mixture savana. This density is compared to by smaller of density of savana ukra (pure savana not yet invasion). Structure old age the nimble walabi with the adult composition 17 tail (77,27%), 2 tail (9,09%) and child 3 tail ( 13,64%). Sex-ratio of reproduction at nimble walabi is sex-ratio at adult walabi, adult female and adult masculine comparison is 1 1. Totalizeing child individual is 3 adult female individual amount and tail is 9, is hence obtained by a harsh birth value of nimble walabi in Udi -Udi of mixture savana of equal to 33%. Nimble walabi mortality in Udi -Udi of mixture savana difficult to be known. From perception activity in field is not found by a dead individual. Pursuant to result analyse the test of chi square , obtained by pattern of nimble spreading spasial walabi in Udi -Udi savana is group in band ecoton by ID = 3,52 (more than 1 group d= 12,36; d > 1,96 group).

This study aimed to determine the capital position and company's performance in Indonesia during the 2008-2012 period and to determine the factors that affected the company's financial flexibility in Indonesian firms. The samples of this study were 45 largest capitalized company listed on the Jakarta Stock Exchange.This study used synthetic rating and the debt service coverage ratio to determine the company's capital position and performance, and used panel data to determine the factors that affected financial flexibility. The results showed that existence a decrease in the default rate, in 2008 the average default rate was 6.12%, in 2009 decreased to 3.99%, in 2010 down to 2.91%, and then in 2011 and 2012 slightly increased to 3.17% and 3.30 %. Based on the results of panel data the factors that affected the financial flexibility is Leverage Ratio, Free Cash Flow, and crisis.

Rapid forest exploitations can cause forest degradation, and eventually may cause the global climate change, because of that, the balance of the forest sustainability must be kept as well. The implementation of silviculture system called Selective Cutting and Strip Planting System is one of several forest harvesting method that consider the importance of forest sustainability. Practically, the system has never been tested to the last cycle. So, it is necessary to conduct some evaluation to the method to assure its sustainability. Estimation of soil quality is one of several ways to evaluate the effectiveness of silviculture implementation on a forest area, Since the soil is one of the major factor that influencing the growth of vegetations, then its quality can be used as an indication of conservation of forest productivity.
