Abstract
Korosi merupakan sebuah proses pengerusakan yang akan dihadapi pada struktur jenis apapun
yang berbahan dasar logam, dimana apabila tidak dikendalikan dan diperhatikan secara serius
maka akan menyebabkan kerusakan yang fatal pada struktur logam, khususnya pada jaringan
perpipaan penyalur gas yang berbahan dasar baja. Korosi memang tidak dapat dicegah atau
dihentikan sama sekali, melainkan dapat dikendalikan atau setidaknya dihambat lajunya.
Adapun terdapat berbagai macam metode perlindungan struktur logam dari korosi, yaitu
diantaranya dengan menggunakan lapisan pelindung (Coating), lalu juga bisa dengan
menggunakan proteksi katodik yaitu dengan cara menjadikan struktur logam sebagai katoda
yang dilindungi. Terdapat dua jenis metode proteksi katodik yaitu metode Impressed Current
dan metode Sacrificial Anode. Pada tugas akhir yang saya kerjakan ini, saya membandingkan
kedua metode proteksi tersebut dari segi teknis maupun ekonomi, untuk mengetahui resiko
teknis dan besar biaya masing-masing metode proteksi katodik tersebut untuk mengetahui
metode mana yang paling tepat untuk digunakan pada pipa penyalur gas PT.PGN Batu Ampar-
Batam. Setelah melakukan analisa, didapatkan metode yang paling tepat yaitu Sacrifial Anode,
dikarenakan tidak memiliki resiko masalah kelistrikan arus pendek (korsleting listrik) serta
untuk total biaya yang dibutuhkan lebih murah dibandingkan dengan Impressed Current, yaitu
berselisih $11147. Setelah didapatkan bahwa metode yang paling tepat adalah Sacrificial
Anode, dilakukanlah perbandingan variasi dimensi dan material anodanya agar diketahui
dampaknya saat sistem proteksi katodik berjalan.
===================================================================================================
Corrosion is a process of destruction that will be encountered on any type of structure that is
made of metal, which if not controlled and be taken seriously, it will cause fatal damage to the
metal structure, particularly in the gas distributor pipeline-based steel. Corrosion indeed can
not be prevented or stopped altogether, but can be controlled or at least inhibited its speed. As
there are various methods of corrosion protection of metal structures, some of them by using a
protective layer (Coating), and also by using cathodic protection that is by making the metal
structure as a cathode that is protected. There are two types of cathodic protection method is a
method Impressed Current and Sacrificial Anode method. At the end of the task I was doing
this, I compared the two methods of protection is technically and economically, to determine
the technical risks and the costs of each of the cathodic protection method to determine which
method is most appropriate for use on a gas pipeline PT.PGN Batu Ampar-Batam. After
analysis, it was found that the most appropriate method Sacrificial Anode because it does not
have the risk of electrical short circuit problem and total cost required for cheaper compared
with Impressed Current, has a difference of $11147. After having found that the most
appropriate method is Sacrificial Anode, the comparison of variation of dimensions and
materials of anode must be perform in order to know the impact while the cathodic protection
system is currently running.
