User Interface Design Software and Hardware Requirements

5. Physical Design

Physical design represented the logical data model in the scheme of the software. Physical design described the data physically where every entity is set according to database software that used in system developed. The physical design of system developed shown on Appendix 1.

4.2.2. User Interface Design

User interface refers to the way a computer program presents and receives information from the users in response to user request. Designing user interface is a process application visualization and interaction between user and the system. For the purpose of developing forestry industry monitoring and evaluation system, the selected software was utilized to design the user – friendly interface. The user interface has been designed such a way, so that it brings easiness to the user in operating the system. The interaction between user and the system was facilitated with the easy selection button. User can use the buttons in order to display map and information requested. The analytical tools i.e. zoom in, zoom out, and pan was also provided in order to help the user in analyzing the location of forestry industry. The user interface of the developed system can be seen in Appendix 2.

4.2.3. DSS Design

The DSS was specifically built in order to assess the performance of forestry industry. To conquer the objective and the user needs, DSS method was selected based on regulation number P.172004 about Procedure in Assessing Sawmill, Chip wood, Veneer, and Plywood industries. There are 10 criteria presented on the regulation, consists of : 1 Industry license; 2 Material requirements; 3 Legality of materials; 4 Capacity setting and product allowance; 5 Efficiency in materials used; 6 Industry financial health; 7 Environment standard quality; 8 RPBBI document; 9 Periodical report availability; 10 Workers used. On establishing regulation, several indicators are available on each criterion where several parameters existing on each indicator. There are 21 indicators and 69 parameters used to assess forestry industry performance. In the process of performance assessment, Government has been grouped the indicators into three 3 category, consists of : 1 Precondition indicators, defined as the indicators that must be fulfilled by industry. When industry can not complete one of the indicators, the industry is directly defined on a worse category. There are seven 7 indicators identified as the precondition category, consists of : a. Propriety of industry license with the regulations; b. Propriety industry location with the location existed on the license; c. All industry materials supplied is secured with a legal document; d. Industry environment friendly operation; e. The availability of materials planning document RPBBI; f. The availability of Laporan Mutasi Kayu Bulat LMKB and Laporan Mutasi Kayu Olahan LMKO data report; g. The availability of forest product examiner. 2 Principal indicators, defined as the indicators that should be completed by the industry. When industry can not complete one of the indicators, the industry is not directly defined on a worse category. There are eleven 11 indicators included on this category, consists of : a. Material is supplied from legal supplier; b. Continuity in supplied materials; c. Reliability of wood administration; d. Industry capacity setting is not exceed the allowance capacity; e. Industry operation is proper with allowance capacity product; f. Efficiency in materials used; g. Industry achieves the recovery rate of production; h. Availability of environment impact assessment report; i. Availability of waste unit treatment; j. Propriety of material plans and realization; k. Availability of periodical activities report; 3 Contribute indicators, used to assess industry activities that contribute to the industry effort. There are three 3 indicators included on this category : a. Availability of business plan; b. Attaining of financial health; c. Availability of joint work commitment between industry and labors. In general, the schema on performance assessment procedure can be seen on Figure 4.8. Figure 4.8. Schema on performance assessment procedure Range of assessment performance value was set into several categories performance, consists of :

A. Very good, if the total weighted value is more than 80 and less and

equal 100 and fulfilling the criterion and indicator on precondition and principal indicators category;

B. Good, if the total weighted value is more than 60 and less and equal 80

and fulfilling the criterion and indicator available on precondition and principal indicators category;

C. Adequate, if the total weighted value is more than 40 and less and

equal 60 and fulfilling the criterion and indicator available on precondition indicators category;

D. Bad, if the total weighted value is more than 20 and less and equal 40

and fulfilling the criterion and indicator on precondition indicators category;

E. Worse, if the total weighted value less and equal 20 or not fulfilling

one of the criterion and indicator on precondition indicators category. The system has been developed an automatically assessment based on procedure described in Figure 4.8. The rules of performance assessment on developed DSS can be illustrated on Figure 4.9. Figure 4.9. Rules of performance assessment The rule of performance assessment was set based on criteria, indicators and parameters established on P.172004. The assessment begun when the potential users Sub Director of Forest Product Manufacture, Sub Director of Production, and Sub Director of Marketing and Industry Assessment use and input their assessment through the system. When industry assessed can not complete one of precondition indicators, then the system will automatically defines the industry performance on worst category. In the contrary, the system will directly calculating the weighted value on precondition, principal, and contribute indicators based on preferred parameters. The total weighted value then used to define the industry performance category refer to the classification range of value.

4.2.4. Software and Hardware Requirements

Identification of software and hardware required was done by analyzing the possibility software and hardware that suitable used for developing the system. In development process of the system, software required to construct the database system, to support the GIS application, and to develop the DSS and Information System. The database software is required for defining a database, stores the data, and supports a query language. The database software was used to support the management of data i.e. conserving space of data, retrieving data rapidly, sharing data with multiple users at the same time, and providing backup and recovery of data. Even today many database software able to construct the database. However, each database has unique strengths and weakness that should be considered to be selected. GIS is the essential system that can provides information about the feature referred to the geometrical orientation, shape, size and relative position from other features. On process development of the system, GIS was used to provide visual information related with forestry industry location. The GIS software required to process forestry industry data spatial i.e plotting the location of forestry industry and organizing non spatial data attributes related with the feature of spatial data. The process development of DSS and Information System used software to construct the programming language and operating the system. Here, the programming language is utilized to create functions for querying or retrieving data from a relational DBMS, to generate a connection function on DBMS, and used to design the user interface. In order to support the development process and to test the application work properly, the suitable hardware is required. Mainly, hardware selected is related with their capacity and capability specification for storing the data and to hold the program code RAM – Random Access Memory, capability in interpreting computer programs instructions and processes data Processor, and specification of the analog computer display standard VGA – Video Graphic Array. Those specifications were become a reference in selecting the suitable hardware.

4.3. Implementation Stage

4.3.1. Hardware and Software Selected

Based on hardware and software requirement analysis, the hardware and software selected use on development process of the system was described on Sub Chapter 3.4. Microsoft Access has been selected to be used for developing the database system. The capability of Microsoft Access in visualizing, manipulating tabular data, and querying relational data used as a basic consideration for selecting this software. Microsoft Access uses a database engine that can store data directly and also can mediate storage and retrieval of data using other engines i.e. Microsoft Visual Basic for Applications VBA code for creating advanced customizations. The maximum file size of Microsoft Access that achieves 2 gigabytes minus the space needed for system objects and 32,768 maximum numbers of objects in a database considered as a suitable selection to build forestry industry database. ESRI ArcView has been selected to process forestry industry spatial data. The selections were based on the ability of the end users in operating the software and software suitability for developing the system. Microsoft Visual Basic 6.0 and ESRI MapObjects were used to develop decision support system and application of information system. In development process of the system, Microsoft Visual Basic was utilized to create syntaxes for querying or retrieving data from a relational DBMS, connection to DBMS, and used to design the user interface. MapObjects is a set of mapping software components to add maps on the applications. This software used to viewing the location of forestry industry or others spatial data. On the implementation, this
