Peran Ruang Terbuka Hijau pada wilayah perkotaan sangat penting untuk mengurangi kejenuhan masyarakat perkotaan. Selain fungsi ekologis, ruang terbuka hijau juga bagi melakukan interaksi sosial budaya, estetika dan ekonomi. Oleh karena itu pemerintah menetapkan dengan undang-undang bahwa setiap kota harus menyisihkan 30% dari luasnya (RTH) dalam rencana daerahnya. Mojokerto mengalami perubahan ...

One of the main concerns of an underground coal mining engineer is the safety and stability of the mine. One way that the safety and stability can be ensured is to know and understand the coal mine geology and how it reacts to the mining process. One technique that has shown a lot of success in the coal mining industry for geologic technical evaluation purposes is the coal mine roof rating (CMR...

Reclamation under the strict requirements of the federal Surface Mining Control and Reclamation Act of 1977 requires a high level of knowledge of plant growth r e q u i r e m e n t s in r e l a t i o n to geochemical factors on each mine site. A desirable reclamation goal would be to consider all feasible alternatives for creating productive soils and attractive landscapes. The raw materials fo...

This paper describes the effects of igneous intrusions on pore structure and adsorption capacity of the Permian coals in the Huaibei Coalfield, China. Twelve coal samples were obtained at different distances from a ~120 m extremely thick sill. Comparisons were made between unaltered and heat-affected coals using geochemical data, pore-fracture characteristics, and adsorption properties. Thermal...

Tests of space-time interaction detect clustering of events in space and time in excess of “any purely spatial or purely temporal clustering” (Kulldorff, 1998, pg. 58). These tests are widely employed in studies of crime (e.g. Knox, 2002; Grubesic and Mack, 2008) and disease (e.g. Petridou et al., 1996; Rogerson, 2001). By simultaneously considering both the spatial and temporal dimensions of t...
