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
software was combined with Microsoft Visual Basic and Microsoft Access using an ActiveX control OCX and a set of over twenty ActiveX Automation objects.
4.3.2. Database Implementation
In database implementation, each table on physical design has been translated into physical condition on information system and decision support
system environments as seen on Figure 4.10.
Figure 4.10. Physical condition of database on information system environment
4.3.3. Code Constructing
A. Information System
In general, the physical database as illustrated in Figure 4.11 created by coding it in a programming language written on Microsoft Visual Basic. The
syntax was coded and used to create a connection and functions for storing, retrieving and controlling data.
Simple Code
Set Cnn = New ADODB.Connection Cnn.CursorLocation = adUseClient
strCNString = Data Source= tanda Cnn.Provider = Microsoft Jet 4.0 OLE DB Provider
Cnn.ConnectionString = strCNString Cnn.PropertiesJet OLEDB:Database Password = mahoni
Cnn.Open Set ch = lstPrimer.ColumnHeaders.Add
ch.Text = No ch.Width = 500
Set ch = lstPrimer.ColumnHeaders.Add ch.Text = Type of Product
ch.Width = 2000 Set ch = lstPrimer.ColumnHeaders.Add
ch.Text = Allowance Capacity ch.Width = 1500
ch.Alignment = lvwColumnRight Set ch = lstPrimer.ColumnHeaders.Add
ch.Text = Unit ch.Width = 1000
ch.Alignment = lvwColumnCenter Set ch = lstPrimer.ColumnHeaders.Add
ch.Text = Rendemen ch.Width = 1500
ch.Alignment = lvwColumnRight Set rs = New ADODB.Recordset
rs.CursorLocation = adUseClient rs.CursorType = adOpenStatic
rs.LockType = adLockReadOnly Set rs1 = New ADODB.Recordset
rs1.CursorLocation = adUseClient rs1.CursorType = adOpenStatic
rs1.LockType = adLockReadOnly rs.Open SELECT FROM U_izin_kapasitas WHERE iphhk_id =
CurrentID _ AND kode_produk = kode_prod , Cnn
The result of the syntax above can be seen in Figure 4.11
Figure 4.11. Retrieving data using syntax on physical database By referring to Figure 4.3, main page of the system was created by coding
and designing in a programming language. This main page is equipped with map to indicate the location forestry industry and forestry industry supplier. Main page
allow user to explore the map just like using other map viewer software. User can do zoom in and zoom out to the map and also gathering information from the map
by using information tool as described in Figure 4.12.
Figure 4.12. Main page of the system
Main page also allow user to find out the information of forestry industry company profile, licenses, materials, production, machine, labors, financial,
environment, reporting, and performance by selecting to the intended industry and list information as described on Figure 4.13.

B. Decision Support System Tool Constructing
For constructing DSS tool in order to evaluate forestry industry performance, the capability of Microsoft Visual Basic 6.0 as programming
language has been explored. Figure 4.14 shows form of DSS tool for assessing forestry industry performance.
This application allows the sub directorates assessing the industry performance by selecting the criterion and indicators provided on the assessment
form. The indicators available on the form have been categorized as explained on
Sub Chapter 4.2.3 DSS Design. The result can be seen by selecting Performance on information list presented in main page of the system.

4.3.4. Testing A. Data Inputting Through the System
Testing was done by running the prototype into one personal computer and inputting data of forestry industry. In order to access into the system, the users
will be asking to enter their username and password on login page. Figure 4.15 shows the login page for the user.
By referring to Figure 4.6 DFD, the system has been design to limit the data accessed input and edit data of each sub directorate. This limitation was
based on scope of their data report handled. In order to distinguish access of the users, different username and password has been implemented on the system login.
Figure 4.15 Login page of the system Limitation of data access between sub directorate applied for data input
and data edit through the system. For the implementation, list of data input has been set to be active based on the user access. Figure 4.16 describes list of data
input that can be access by Forest Product Manufacture Sub Directorate. For the testing purpose, the prototype was installed and run on each sub
directorate. Connection between sub directorate and server has been set as local area network LAN. By referring to Figure 4.6 DFD and Figure 4.7 Entity –
relationship diagram of developed system, each table on the database was designed to be connected by IPHHK_id. This requirement was carried out on the
system of data input and data edit. It means that data input can be work if the industry id defined firstly. Forest Product Manufacture Sub Directorate has the
authority to define the industry id by inputting the industry profile data. After the industry id has been defined by the system, others sub directorate can input or edit
the data based on their data handled. The testing diagram of the system illustrated on Figure 4.17.
Figure 4.16. List of data input for Forest Product Manufacture Sub
Directorate
The testing was carried out by inputting forestry industry data of H.M. Jamil Sawmill. The process was begun by selecting input data on main page
interface and general information on the list of data input. There are several options that should be fulfilled as described on Figure 4.18.
Figure 4.17. Testing system diagram
Figure 4.18. Form used to input a new data
After the general data of forestry industry has been inputted through the system, location of industry then plotted into the villages map area by processing
it on ESRI ArcView. Plotting was based on the address of industry i.e. name of village, sub region, and region provided on company profile data. Figure 4.19
describes the process of plotting location of industry.
Figure 4.19. Plotting industry location To view data that has been inputted through the system, selecting the
criteria on main page of the system was used to load the data and location of the industry i.e selects the location of industry province, group of industry, and
industry name as described on Figure 4.20.
Figure 4.20. Selecting criteria to view data inputted on the system When all criterions have been selected, then the system will find and zoom in
automatically to the intended industry location as described on Figure 4.21.

B. Forestry Industry Performance by Using DSS Tool
Testing the DSS tool for assessing industry performance was done by running the prototype into one personal computer on Marketing and Industry’s
Assessment Sub Directorate. On structural, this directorate has an authority to assess the industry performance, however, the system was designed to involve
others sub directorates on Forest Production Management Directorate General in assessing the performance. Figure 4.22 describes the diagram testing of DSS tool.
Figure 4.22. DSS diagram testing Figure 4.22 describes the process of performance assessment by the end users.
The user was assessed based on indicators, criteria, and parameters provided on assessment form as described in Figure 4.23.
Figure 4.23. Performance assessment form on DSS The assessment process begun by selecting the industry name and year of
assessment provided on drop list of form. Optional button was provided to select parameters on each criteria and indicators available. The assessment test resulted
can be seen by selecting Performance on information list presented in main page of the system. The system will categorize the industry performance automatically
based to the cumulative weighted value upon selected parameters. Performance assessment resulted can be seen on Figure 4.24.
Figure 4.24. Performance assessment test resulted
4.3.5. System Capability
For supporting the decision making of the end users in monitoring and evaluating forestry industry, the system also provide some capabilities, consist of :
1. Detecting the properly of planning and realization material supplier. The system has been designed to detect the obedient of industry on the
establishing regulation; for having supplier that identical in material
planning and realization. Figure 4.25 shows an example case on PT. Tanjung Johor Wood Industry - Jambi
which planning their material
supplies from PT. Intrado Jaya Intiga. However, the realization of
material supply was not fulfilled by the same supplier. There were 102
suppliers that have been identified on industry material realization as described on Figure 4.26.
Figure 4.25. Supplier material planned by industry
Figure 4.26. Identification the supplier on material realization blue rectangle
2. Detecting the volume of material supply that exceeds the annual
allowable cutting RKT. The annual allowable cutting refers to the volume of wood trees that
permit to be cutting in a year. Mainly, the volume is refers to the amount of industry material supply. This system has been designed to
detect the production wood material that exceeds the allowable cutting. This system can calculate and detect the total volume of supplied
material and the supplier that exceeds the allowable cutting. Figure 4.27 describes how the system works in detecting the volume of material
supply that exceeds the annual allowable cutting RKT.
Figure 4.27 describes a list of supplier of PT. Barito Pacific Timber Tbk. Unit Banjarmasin
and the total volume of material supplied which identified exceeds their allowable cutting RKT. PT. Aya
Yayang Indonesia forest concession is one of supplier that has total capacity production of 32328.47 m
3
and supplying 33437.62 m
3
to PT. Barito Pacific Timber Tbk. Unit Banjarmasin.
Figure 4.27. Detecting the exceed material supplied green rectangle
3. Detecting the validity license of forest product examiner Forest product examiner was required in order to assure the legality of
forestry industry material used. To certify their assessment, each forest product examiner has been equipped with a license published by Balai
Sertifikasi Pengusahaan Hasil Hutan BSPHH. The license, however, has been limited in three 3 years usage and has to be renewed in order
to improve the ability of forest product examiner. The system has been designed to detect license validation time of forest product examiner.
Figure 4.28 shows how the system marks the examiner who has expire
license in PT. Basirih Industrial Coorporation South Kalimantan.
Figure 4.28. Identifying validity license of forest product examiner
4. Detecting production that exceed the product capacity allowance The established regulation arranges the amount of industry production
based on product capacity allowance. This obligation used to restrict and to make efficient the industry material used. In order to identify the
obedient of industry in production, the system has been designed to detect automatically production that exceeds the product capacity
allowance. Figure 4.29 describes how the system automatically detect
sawmill production belong to PT. Tanjung Johor Wood Industry
identified on red rectangle. The amount of production until December 2003 was achieved 26,123.717 m
3
where the product capacity allowance is 12,000 m
3
per year.
Figure 4.29. Detecting production that exceed the product capacity allowance
5. Mapping the material distribution In order to support decision making related with trend in wood material
distribution, the system has been designed to visualize it by adopting the capability of GIS. Map of material distribution was developed to
identify sources of material and supporting analysis to indicate the potential forest supply on each province as seen on Figure 4.30.
Figure 4.30 shows map of material source distribution of PT. Tanjung Johor Wood Industry, Jambi
in 2003. Based on visualization resulted,
it seen that industry has been supplied from supplier on Jambi province
inside and others provinces outside. The comparison of source material supplied inside and outside province was informed on a form
by clicking one of the analytic tools yellow rectangle.
Figure 4.30. Mapping the material sources distribution
In order to make efficient the requirements of industry material, ideally, source of material supply should be located inside the industry province.
However, not almost location can be founded on the related province Haeruman, 2000. This phenomenon was described on Figure 4.30.
Almost material sources of PT. Tanjung Johor Industry fulfilled from Jambi forested area 73.79; only a part 26.21 was supplied from
outside of Jambi province. This trend was useful for Government to analyze the potential supply on each province and how to generate the
recovery action of forest area.
