Abstract

Karst environment become an alternative tourist destination as well as to boost local revenues. In karst environments in Grobogan District, Central Java Province, formed Urang Cave, with an interesting endokarst phenomenon. This study aims to do zoning district Urang Cave as tourist sites. The research method is using contour maps as a base map of Urang Cave karst environment geomorphological mapping. Geomorphological data processing is using ArcView GIS 3.3 program. Land use map refers to RBI, scale 1:25.000. Geomorphological analysis refers to the Ministry of Energy and Mineral Resources No. 1456.K/20/MEM/2000, and petrography. Each development zone is analyzed its geophysical environmental element, then set scoring and value summation. For comprehensive environmental element analysis, chemical analysis of rocks, and water-soil chemistry. In reference to Minister of Energy Mineral Resource decrees No. 1456/K/20/MEM/2000, Urang Cave zoning defined into 3 (three) zone, as follow: the Protected Zone, Cultivation Zone 1, and Cultivation Zone 2. Protected Zone, consists of Urang Cave tunnel/hallway with a unique spheleothem in it. This zone as a cave tracking site tourism, potential to produce karst water as a decent drinking water while maintaining hardness. Cultivation Zone 1 is spreading about 200 m in distance from outer appearance of spring around the cave hallway. In this zone mining of cave sediments may be done in the inactive form caves, without changing the state of the existing major exokarst morphology. Cultivation Zone 2, an outer zone, located farthest from the tunnel/hallway Urang Cave. Utilization of this zone as a limestone mining quarry, although only on a small scale.

Abstract

Aplikasi industri informatika saat ini telah berkembang sangat luas dalam segala sektor. Berbagai aplikasi telah dirancang yang sesuai dengan kebutuhan industri di segala bidang. Salah satu bidang industri yang banyak menggunakan teknologi informatika adalah industri pertambangan. Industri Pertambangan sangat membutuhkan teknologi informatika dalam kegiatan pengelolaan sumberdaya mineral dan merupakan aspek yang sangat penting dalam meningkatkan kinerja pertambangan saat ini. Aplikasi beberapa software sangat diperlukan dalam berbagai analisis, termasuk jenis aplikasi untuk menentukan distribusi ukuran butiran pada batuan. Aplikasi yang digunakan adalah split desktop software. Aplikasi software ini sangat akurat dan cepat dalam menganalisis distribusi masing-masing ukuran butiran batuan yang dapat mempermudah dan menghasilkan dalam visualisasi bentuk dan ukuran butiran tersebut serta distribusinya. Hasil analisis yang diperoleh akan dijadikan dasar untuk mengetahui karakteristik butiran dalam suatu batuan.  Tulisan ini akan membahas bagaimana cara mengaplikasikan split desktop software dan hasil analisis distribusi ukuran butiran pada batugamping berongga di cavity limestone layer daerah Sale, Kabupaten Rembang, Jawa Tengah. Kata Kunci : Split desktop, Ukuran Butir, Batugamping Berongga
