Judul: Dampak Ekonomi Pengelolaan High Conservation Value Areas (HCVA) di Perkebunan Kelapa Sawit (Studi Kasus PT. Inti Indosawit Subur Kebun Buatan, Provinsi Riau)
Abstrak: The global demand for palm oil was growing rapidly. Palm oil was consumed world wide and constituted the vegetable oil with the highest level of market penetration. Indonesia was the largest producer of palm oil in the world while Malaysia was the leading exporter of palm oil, accounting for 46% of global exports. The production of palm oil was associated with many sustainability issues, including deforestation, erosion of biodiversity and violation of social rights. The Roundtable on Sustainable Palm Oil (RSPO) as the concern these issues of European driven initiative of the World Wide Fund for Nature (WWF). The palm oil estate was rarely focused on the cost and benefit analysis in calculating the economic valuation and financial projection on High Concervation Value Area (HCVA) as the prerequirement of RSPO certification. This research was done to analyze the economic impact of HCVA management in palm oil estate. The research spent for three month in PT IIS (Riau). The method was used; The Total Economic Value (TEV) analysis, the cost benefit analysis, the financial and economic analysis, and the stakeholder analysis on managing HCVA. Based on this calculation, the amount of TEV showed Rp 1.321.847.970,00 per year for PT IIS Kebun Buatan. There were three scenarios used; with HCVA, (NPV: Rp 655.616.430.602,00), with HCVA+0.35% (NPV: Rp 664.005.845.480,00) and without HCVA (NPV : Rp 667.346.030.004,00). Premium price for 0.35% was not feasible for the palm oil Industry. The stakeholder analysis showed the palm oil industry, GAPKI and Sawit Watch as the key players for the HCVA management.

Judul: Model pengelolaan perkebunan inti rakyat kelapa sawit berkelanjutan (Studi Kasus di PT. Perkebunan Nusantara VII, Kabupaten Muara Enim, Sumatera Selatan)
Abstrak: A primary issue in the management of oil palm plantations own by both nucleus smallholder and independent farmers currently is still sectoral and not based on the consideration of multi-sectoral and multi-dimensional. This causes multiple losses such as the loss of income’s farmers, environmental deterioration, and social problem. The objective of this research is to design a management model for sustainable nucleus smallholder of oil palm which meet aspects of biophysical (planet), economic (profit), and social (people). This research was conducted at PT. Perkebunan Nusantara VII, Muara Enim District, South Sumatra Province, where located between 4°-6° south longitude and 104°-106° east latitude, in July 2011 to September 2012. The result of this analysis indicate that soil of land use of oil palm plantations contain C-org less than the forest soils, especially in the surface layer (0-20 cm). This indicates the occurrence of land degradation at the sites caused by erosion mostly at the surface layer of soil. Sustainability analysis of oil palm plantation showed that the economic dimension has the highest sustainability index of 88.97, followed by social index of 81.02, technological index of 69.17, ecological index of 68.21, and the the lowest is 30.71 for institutions index. Result of this analysis was also revealed that sustainability of plantation and motivation of employees are determined by the company support i.e. PT. Nusantara Plantation VII. Based on the multi-dimensional index of sustainable nucleus-plasma oil palm plantation was 67.67 meaning that is quite continuous. Model development shows that the implementation of soil conservation brings a consequences of increasing outcome every year. In the year 2010 was allocated IDR 1,801,271,159.73 and predicted to remain increase to IDR 4,384,575,338.50 in year 2040. If farmers follow the fertilization protocols used by nucleus smallholder, it will increase profits to IDR 7,446,289, - per hectare.

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.
