Stylized models of Faustmann formula to be applied in selective logging regime have also been studied extensively in multi-age and multi-species forest. In general, natural forest managers in Indonesia have not adopted the Faustmann formula in their management decisions. Sustainability aspect in natural forest management is applied based on silvicultural consideration, i.e. measuring residual stand that is able to be harvested in the next cutting cycle. This study aims to analyze the application of Faustmann formula in the current selective logging regime in Indonesia (i.e. TPTI), so that the natural forest managers may gain maximum profit and sustainable. This study is a qualitative research based on literature review. The results of this study show that under deterministic growth model (i.e. matrix transition model) and robust damage model (i.e. transition matrix with different damage proportions on each species and diameter class), the Faustmann formula can be applied for selective Logging regime in Indonesia.

A method that is widely applied to reduce heavy metal contamination is bioremediation. Selection of bacteria that have potential reduction of heavy metal contamination in soil is very important in bioremediation process. The first step to select the potential bacteria is identification of samples. The purpose of this study is to identify existings bacteria in pond after nickel mining area PT. Antam, East Halmahera. Methods used in this research are isolation and identification of bacteria by conventional methods includes morphological, physiologica , l and biochemical test. Identification using Bergey’s Manual Determinative. The results showed there are 6 genera types of bacteria there are Bacillus, Esherichia , Enterococcus, Pseudomonas , Staphylococcus , dan Klebsiella , with 18 species in water of nickel post mining.

Based on SWOT analysis which conducted by calculate score of external factors and internal factors, the suitable strategy was WO strategy which utilized opportunities to suppress the weaknesses at third quadrant.
