Belajar Membuat Jaringan Komputer(Part1)

Membuat jaringan?Apa itu jaringan?dan Bagaimana cara membuatnya? Disini saya akan mencoba untuk menjelaskan bagaimana cara membuat jaringan sederhana. Tapi sebelumnya mungkin saya akan menjelaskan sedikit tentang apa itu jaringan. Jaringan, mungkin qta sering mendengar kata itu tp tidak banyak yg mengerti apa yang dimaksud sebenarnya. ok begini saja qta ibaratkan seperti jaringan yang ada ditubuh qta, setiap perangkat yang ada saling terhubung dengan fungsi untuk saling bekerja sama walaupun setiap perangkatnya memiliki fungsi sendiri-sendiri. Sebuah sitem dikatakan jaringan komputer jika terdapat satu buah komputer yang melayani seluruh tugas-tugas komputasi suatu organisasi yang telahdiwakili oleh sekumpulan komputer berjumlah banyak dan terpisah-pisah akan tetapi dapat saling berhubungan dalam melaksanakan tugasnya. Sekarang qta sudah tw apa itu yg dimaksud dengan jaringan komputer,lalu bagaimana cara membuatnya,sebelum qta memulai langkah pembuatannya ada baiknya qta coba perhitungkan dulu berapa biaya yang akan qta keluarkan dalam pembuatannya. Misalnya saya akan membuat suatu jaringan dalam satu ruangan yang berukuran kurang lebih 20 x 20 meter dan denah ruangannya seperti gambar di bawah ini :
Gambar denah ruangan
Lalu dalam ruangan tersebut akan qta letakkan 30 buah komputer yang saling terhubung dalam satu ruangan tersebut. Ilustrasinya dapat dilihat pada gambar berikut ini:
Gambar ruangan dengan settingan LAN
untuk membuat jaringan qta harus tw berapa biaya yang akan dibutuhkan dalam pembuatannya.Dan kita akan mencoba menghitung kira-kira berapa biaya yang dibutuhkan pertitiknya. Sekarang kita akan menghitung berapa jumlah kabel yang diperlukan,untuk Jarak antar PC adalah 1,5m dan perhitungannya sbb:
  • Jarak switch0 dengan server adalah 2m
  • Jarak antar switch0 dan switch1 adalah 18m
  • Jarak switch0 ke PC-1 s/d PC-6 adalah 1,5+3+4,5+6+7,5+9+10,5=42
  • Jarak switch0 ke PC-21 s/d PC-29 adalah 3,5+5+6,5+8+9,5+11+12,5+14+15,5 = 85,5m
  • Jarak switch1 ke PC-7 s/d PC-10 adalah 6,5+5+3,5+2 = 17
  • Jarak switch1 ke PC-11 s/d PC-14 adalah 6,5+8+9,5+11 = 35m
  • Jarak switch1 ke PC-15 s/d PC-20 adalah 13+14,5+16+17,5+19 = 80

Jadi, total kabel yang dibutuhkan adalah 2+18+42+85,5+17+35+80 = 279,5m Dari perhitungan tersebut kita dapat melihat bahwa kabel yang terpakai adalah sepanjang 279,5m,Dan karena 1 roll kabel itu berisi 300m, untuk itu kita membutuhkan cukup 1 roll saja. Dan total rincian biaya keseluruhannya dapat kita perhitungkan sbb:

  • Kabel UTP : 1 roll * @700000 = Rp. 700.000
  • Konektor RJ 45 : 1box = Rp. 25.000
  • Switch 24 Port : 2 * @ 700000 = Rp.1400.000
  • Etherned Card : 30 * @30000 = Rp. 900.000
  • Tang Crimping : 2 * @ 75000 = Rp. 150.000
  • Kabel Tester : 1 buah = Rp. 50.000
  • Biaya Operasional : 1 hari * 4orang * @50.000 2 hari * 200.000 = Rp. 400.000

Dan jika perhitungan diatas itu qta jumlahkan maka totalnya adalah Rp. 3.675.00. Jadi biaya untuk mengerjakan satu titiknya adalah : Rp. 3.675.000 / 30 unit = Rp. 122.500/titik

Yup itu adlah perincincian biaya biaya yang qta butuhkan untuk per titiknya, so bagaimana langkah-langkah dalam membuatnya ? ok saya akan menjelaskannya satu per satu 'dilihat baik2 ya! Sebelumnya qta siapkan dulu alat dan bahan apa saja yang dibutuhkan untuk membuat jaringan.Berikut adalah alat dan bahan yang qta butuhkan:

1. Rj 45 konektor

2. kabel UTP

3. Switch ( 2 unit @ 16 port) 4. Tang crimping ( 2 buah) 5. Alat tester Setelah setelah alat dan bahan sudah terkumpul lengkap berarti kita telah siap untuk memulai membuat jaringan, berikut adalah langkah-langkahnya: 1. Kupas kedua ujung kulit luar kabel UTP menggunakan Tang crimping panjangnya kira-kira 1,5 cm seprti gambar berikut ini.
2. Pisahkan kabel-kabel tersebut untuk mempermudah dalam pengurutan kabel.
3. Urutkan warna-warna kabel tersebut.
Urutkan Kabel berdasarkan tipe:
Straight : C-PC-H-B-PB-PH-O-PO
Crossleft : C-PC-H-PB-B-PH-O-PO
Crossright: C-PC-O-PB-B-PO-H-PH
4. Potong ujung-ujung kabel untuk meluruskan kabel agar rata.
5. Masukan kabel yang sudah rata ujung-ujungnya kedalam konektor (RJ45).
6. Kemudian tes kabel tersebut pastikan semua titik menyala.
7. Pasang kabel UTP pada switch,untuk pemasangan kita hanya perlu menancapkan satu konektor rj 45 yang telah disambungkan pada kabel UTP tadi ke salah satu switch dan yang satunya lagi pada PC.
Setelah memotong dan memasukan kabel kita setting ip address pada LAN tersebut…. mo taw,gmn cara mensettingnya ??Tunggu postingan berikutnya... TO BE CONTINUE………………………..!
