It results from cooperation between the Government of the Republic of Indonesia and South Korea (Korea-Indonesia Forest Center-KIFC). The location of SEETF ecotourism is within the working area of Perum Perhutani KPH Bogor. This study aims to identify the potential of the existing business in the SEETF and make a feasibility study using financial analysis by employing a discounted cash flow based on the criteria of Net Present Value (NPV), Benefit-Cost Ratio (BCR), and Internal Rate of Return (IRR). Financial analysis shows that SEETF’s ecotourism investment is not feasible. The financial analysis of “forest healing” shows that SEETF’s financial performance could be better while applying an optimal ticket rate. It is also important to note that 76,7% of respondents will revisit SEETF for forest healing

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
