Judul: Perencanaan Lanskap Pasca Tambang Nikel PT INCO sebagai Kawasan Ekowisata di Sorowako Kabupaten Luwu Timur Sulawesi Selatan
Abstrak: Kegiatan pertambangan selain berdampak positif menjadi sumber suplai energi, juga mempunyai dampak negatif diantaranya adalah terjadi perubahan lingkungan terutama degradasi lahan sehingga diperlukan perencanaan total sejak tahap awal sampai pasca tambang. Penelitian yang dilaksanakan di Bukit Butoh lahan pasca tambang nikel PT INCO Sorowako ini bertujuan merencanakan lanskap pasca tambang nikel sebagai kawasan ekowisata yang fungsional dan estetik melalui deskripsi dan analisis kondisi biofisik sumber daya kawasan pasca tambang serta deskripsi dan analisis kondisi sosial ekonomi masyarakat sekitar kawasan pertambangan. Penelitian ini menghasilkan perencanaan kawasan ekowisata dengan berbagai aktivitas, sarana, dan prasarana dengan memperhatikan daya dukung tapak, konservasi, pendidikan, budaya lokal, serta peningkatan kesejahteraan penduduk setempat.

Judul: Perencanaan Lanskap Bekas Tambang Batubara Sebagai Kawasan Wana Wisata di Desa Mandin Kecamatan Pulau Sebuku Kalimantan Selatan
Abstrak: Coal mining with open pit mining systems can change landscape form and soil layers, causing erosion, deprive of vegetation, and land degradation. On the other hand, mining activities have some positive impacts, such as increase national income, improve providing job, provision of energy and economic growth. Refering to such changes need to be made efforts of reclamation. This study located in a post mining areas in Sebuku Island, South Kalimantan Province.The method of this study based on planning process by Gold (1980), consist of preparation, site inventory, site analysis, synthesis, and landscape planning. Descriptive analysis conducted in all aspects, such as land use, topography, and hydrology. Analysis of carrying capacity according to Boulon in Nurisjah, Pramukanto, and Sukijat (2003), calculated based on the average standar of individual within m2/person. The area is suitable to be developed as ‘wana wisata’ based on educative, recreative and conservative by utilizing site-surrounding condition such as lake and post mining high wall which equipped with services facilities for visitors with the sense of natural landscape that are safe and convinient to support the sustainability of the reclamation. The result is a landscape planning that divided the site into 4 zones: welcome area with space covering an area of 1.57 ha, educational tourism zone 6.37 ha, recreation zone 2.32 ha, and conservation zone 170.74 ha. The activity developed on the site consist of indoor and outdoor educational tourism, recreation, and supporting tourism.

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.
