Judul: Perencanaan Lanskap Pasca Tambang Batubara Sebagai Arboretum di Kawasan Tanah Putih Pulau Sebuku Kalimantan Selatan
Abstrak: Exploitation of coal through the open mining system cause negative impacts for environmental sustainability. Land reclamation efforts of post-mining area is the obligation of the mining company involved. It aims to restore the condition as previously. Landscape planning plays the role to optimize the next utilization. This study is conducted in an after coal mines which covers on 223 hectares land area at Tanah Putih, Mandin Village, Pulau Sebuku District, Kotabaru Regency, South Kalimantan. The objectives of this study are to identify the characteristics of post-coal mining and to compose a landscape planning of post-coal mining as an arboretum to implement land, water and biodiversity conservation. This study uses methods including preparation, inventory, analysis, synthesis, and planning. The basic concept of this plan is to develop the post coal mining area as an arboretum conserving land, water and biodiversity especially indigenous plants. The concept was developed into spatial, circulation, activity, facility, and also vegetation concept. Quantitative description and spatial analyze produce a landscape plan and distribution of area as the following: welcome area and service area 0.5%, cultivation area 11%, conservation area 29.7%, education of conservation area 0.8%, collection area 40%, and buffer area 18%.

Abstrak: Landscape exploration mining can cause landscape changes and degradation of landscape. Soil amelioration and reclamation efforts that are being made right now in ex-mining area, but those mainly land re-vegetation and reforestation. Landscape planning to be an Educational Tourism area become most potential thing to utilize the post-mining land in other way. This study was purposed to: 1) identify the physical, biophysical, socio-culture, and tourism aspects 2) analysis and synthesis the potential and constraints 3) propose a post-mine landscape planning as an mining educational tourism. The planning process by Gold (1980) was used with resources approach, which consists of preparation, inventory, analysis, synthesis, and landscape planning stages. Descriptive and spatial analysis were used to determine the suitability of the space. The results showed that welcome area found to be 0,2 Ha (0,3%), service area 1 Ha (1,5%), education tourism indoor area 0,3 Ha (0,4%), education tourism outdoor area 2,1 Ha (3,1%), education tourism support area 9,6 Ha (1%), recreation area 1,5 Ha (2,3%), and conservation area 60,7 Ha (91,4%)

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.
