IV. RESULT AND DISCUSSION
This chapter is discussed about generating MICES-Quan system for evaluating mining company performance. This chapter consists of three major
phases which are analysis of database design, analysis of system evaluation and the implementation in database, information system and web visualization.
4.1. ANALYSIS OF DATABASE DESIGN 4.1.1. Database Design
Database design describes about how data connect to other in term of the user, the needs, and the relationship. MICES-Quan database design explained
with process modeling, conceptual model, logical model, and physical model. The methodology of database design explain the structure approach that uses
procedures, techniques, tools and documentation aids to support and facilitate of design.
A design methodology consists of phases each containing a number of steps, which guide the designer in the techniques appropriate at each stage of the
project. A design methodology also helps the designer to plan, manage, control, and evaluate database development projects. It is a structured approach for
analyzing and modeling a set of requirements for a database in a standardized and organized manner Connolly and Begg, 2002.
a. Process Modeling
Process modeling explains about interconnecting between data input, processes and data stores which is visualizing with data Flow Diagram DFD.
DFD describes user identification and the needs in the system visualization with context diagram Figure 4.1. DFD also can be figured out in several
levels of connection and relationship Figure 4.2. Context Diagram figures out the user with their need to the system. There are three major users that will
include to MICES-Quan system which are energy and mineral resources DTMB, mining company, and public.
Figure 4.1 MICES-Quan Context Diagram ♣
Directorate of Mineral and Coal Engineering DTMB, Directorate General Geology and Mineral Resources, Department of Energy and
Mineral Resources, as government representative who can evaluate the performance of mining company.
♣ Mining Company as the actor of the system which can submit their
periodical report digitally through internet yet manual report submitted. ♣
Public which consists of academician, researcher, mining association, environment association, NGOs, and local community. They can be an
observer only to browse the information and also can be an evaluator depends on their capabilities.
