performance, the external entities Sub Director of Forest Product Manufacture, Sub Director of Production, and Sub Director of Marketing and Industry Assessment were used the system and data that have been inputted as defined on the first and second process. Referring to the overall process, there are several outputs provided, i.e.: 1 Information of forestry industry activities; 2 Forestry industry performance; 3 Location of forestry industry and material supplier; 4 Map of material distribution. All those output were used to monitor and evaluate forestry industry by the external entities.

3. Conceptual Model

A conceptual model used to describes the data content on the system proposed. On conceptual model, the data was drawn into Entity – Relationship E – R diagram and use a symbol to illustrate the relationship between data. The E – R diagram consists of entities, relationships between entities, and attribute of entities. The E – R diagram is used to represent the meaning of data. Figure 4.7 illustrated the E – R diagram of the system proposed. Here, the entity identified as a table that has independent physical or conceptual existence i.e. forestry industry U_Perusahaan_Umum, forestry industry product U_Jenis Produk, and workers U_Tenaga_Kerja where the attributes describes the properties of entity i.e IPHHK_id, Nama_IPHHK, jenis_produk, etc. A relationship was drawn with a line connected between entities. The order of relationship defined as a set association between two or more participating entity types. The order was expressed as one to one relationship 1:1; one to many relationship 1:M; and many to many relationship M:M. For the relationship of entity “forestry industry” with “forestry industry product” the order can be categorized as 1 : M relationship. It means that “one industry can have many kinds of product”.

4. Logical Model

Logical modeling phase is related to the actual implementation of the conceptual data model in a commercial DBMS. Logical model defines as the basic organization of a database. Table 4.2 described the logical model of the system developed. The table list of all files in the database, the number of records in each file, and the names of each fields. Table 4.2. Logical data model of system developed No Category Entity Attributes U_Alamat_Prsh IPHHK_id, jl_pusat, desa_pusat, kec_pusat, kab_pusat, telp_pusat, prov_pusat, jl_wakil, desa_wakil, kec_wakil, kab_wakil, telp_wakil, prov_wakil U_izin_kapasitas IPHHK_id, kode_produk, jenis_produk, kelompok_industri, kapasitas_izin, satuan, kapasitasa_terpasang, satuan_pasang, rendemen, kebutuhan_bb, satuan_butuh, jenis_bb U_Perusahaan_Umum IPHHK_id, Nama_IPHHK, No_akta_berdiri, notaris_berdiri, npwp, investasi_rp, investasi_dollar, notaries_saham, tgl_saham_notaris, no_saham_notaris, komisaris_utama, direktur_utama, jenis_pnm_modal 1 Profile U_Jenis_Produk Kode, jenis_produk, kelompok_industri, nomor BB_jenisBB Kode, jenis_BB BB_kebutuhan IPHHK_id, jenis_produk, rendemen, kebutuhan_bb, jenis_bb, nomor BB_Pemasok_RKT Pemasok_id, tahun, rkt, stock BB_Pemenuhan IPHHK_id, tahun, bulan, Jenis_BB, Realisasi, pemasok_id, jenis_kayu, kategori_pemasok, kode_bulan, iphhk_prov BB_Penggunaan IPHHK_id, tahun, bulan, Jenis_BB, Jenis_produk_jenis_kayu, pengguna_bb, keterangan, kode_bulan, nomor, kategori_industri, kelompok_industri BB_Produksi IPHHK_id, tahun, bulan, kelompok_industri, jenis_produk, kategori_industri, Jenis_bb, realisasi_prod, persentase_prod, keterangan, iphhk_prov, kode_bulan, nomor, satuan BB_Prsh_Pemasok Pemasok_id, Nama_Prsh, kategori_prsh, kel_prsh, LH, LHP, LBE, EL, EB, EV 2 Materials BB_Rencana_Pemenuhan IPHHK_id, tahun, pemasok_id, Jenis_bb, jenis_kayu, jumlah_kategori_pemasok 3 Machine Mesin no_m, IPHHK_id, tahun, kategori, jenis_mesin, unit, merk, kapasitas, Negara_pembuat, tahun_buat, tahun_pasang, keterangan, tipe
