Hardware and Software Required Data Requirement

3.2. Material and Tool

3.2.1. Hardware and Software Required

As an integrative system, DSS tool is constructed by several components. This tool can properly work on recommended hardware below, perhaps with lack of weakness and troubleshooting. a. Required Hardware. • Desktop PC with Windows XP Home Edition OS • Processor : Pentium III 450 MHz • Memory : 128 MB of RAM • Storage : 40 GB • Plotter HP Design-jet 500 PS Pantone Digital Color • Printer HP Desk-jet 3535 b. Software, to build the prototype of DSS tool by integrating some of the software, i.e.: • Microsoft Visual Basic 6.0 Used for coding and constructing the prototype of DSS tool as the product of spatial information system. • Microsoft Access Powerful ‘Microsoft’ database application software, which is part of Office Suite, used to store and retrieve reclamation data. • ESRI Arc View 3.2 This software used in spatial data preparation such administrative map, mining location map, road map, contour map, geological map, etc • Esri MapObject 2.1 This ESRI’s product combined with Microsoft Visual Basic 6.0 used for building map application.

3.2.2. Data Requirement

Data required in this study consist of spatial data of project area which gathered from National Survey and Mapping Agency BAKOSURTANAL and DEMR and non spatial data gathered from reclamation division of DEMR. a. Spatial Data • Project Area Contour maps on scale 1:10.000 • Project Area Geological maps on scale 1:10.000 30 • Mining Project Area layout map on scale 1:5.000 • Reclamation Planning Project Area map on scale 1:5.000 b. Non Spatial Data • Technical Data - Soil and rock types - Slope in percent and distances in kilometer between any mining facilities, usually used to determine material handling equipment movement - Building dimensions in cubic meter with material types brick, concrete, metal, iron pipe, belt conveyor, wood, wires, etc and physical structure characteristics, in order to determine mine facilities removal - Heavy equipment types dozer, ripper, excavator, grader, loader, scraper, dump truck, etc • Non Technical Data - Specification of vegetation - Price list of Heavy equipment rental - Cost of specific material and the removal - Price list of specific vegetation - Price list of fertilizer - Price list of fuel, oil and lubrication - Additional banking information billing rate, inflation rate, etc c. Missalaneous Data • Administrative; province and regional boundary map on scale 1:250.000 BAKOSUR- TANAL, 1999 • Road and river map on scale 1:250.000 BAKOSURTANAL, 1999 • Mining companies location and information Administratively, PT.NNT is located at Batu Hijau, West Sumbawa Regency of West Nusa Tenggara Province. It has almost 1,900 ha opening area that consists of 28 ha main pit and the rest for supporting area, where should has warranty to manage annually. Technically, this is a surface mining company that exploit copper and gold. The data used for this research was acquired from DEMR in form of hard copy of mining company program in proposing their Reclamation Bond. 31
