type, which consist of characteristic of specific plant for re-vegetation activities. Activities stage consist structure demolition and structure disposal, earth moving
and re-vegetation whereas need supply data from input data. Then processing stage consists of financial accounting process to produce the amount of
Reclamation Bond.

3.3.3.2. User Need Analysis
One stage before constructing DSS tool for Reclamation Bond is analyzing user needs. Here, important aspect specifies users and their limitation in using the
system. In general, there are three main users included Government, Enterprise and Public. Those can distinguish based on their access authority, as follows;
Administrator
The administrator is the DEMR, Provincial or Regional Officers, who has full accessibility to handle the whole systems, include the database in term
of periodical monitoring reports of mining activity and giving mark of final evaluation regarding to their performance.
Applicant
The applicant here is Enterprise or Mining Company, who has access and responsibility for actual Reclamation Bond data input, which calculated by
company.
34
Guest
The Guest is public, mining association or mining community as observer.

Construction
The DSS comprises 2 two main parts namely Direct Cost and Indirect
Cost. The DSS construction is presented in the flowchart as shown in Figure 3.5.

The Mining Rehabilitation Bond System is designed to support decision making, in order to minimize DSS implementation, data base manipulation
through Visual Basic programming language. Beside direct cost analysis and indirect cost analysis, there is also manual analysis to perform additional data for
structure demolition calculation and earth moving activities. This process can be handled directly by mining company itself or DEMR as necessarily. The main
focus of this system design is to estimate the amount of escalation per year that have to meet mining company’s reclamation cost planning.

IV. RESULT AND DISCUSSION
This chapter will describe how reclamation model is simulated. The implementation of several formula of reclamation model, which is combined with
mined existing data and supported also with spatial data can be seen more confidence. This chapter discusses about selecting hardware, software, and
implementing the prototype as well as coding, user interface design, and testing. 4.1.
System Analysis 4.1.1.
Database Design
Database design explains interconnecting among data to user guidance performance. Database design of rehabilitation bond is figured out as flow of
process in conceptual, logical and physical model. Connolly and Begg 2002 explained that methodology design consists of
phases, where each phases containing a number of steps, which guide the designer in designing. It also helps the designer to plan, manage, control, and evaluate
database development projects and structured approach.
4.1.1.1. Process Modeling
Process modeling describes relation between user and system, which is
represented by data Flow Diagram DFD. DFD describes user identification and
the needs throughout context diagram Figure 4.1. Moreover DFD can be derived in several levels of connection and relationship Figure 4.2.
