Abstract

Korosi menjadi peristiwa yang tidak dapat dihindari oleh setiap material logam. Korosi dapat terjadi kapan saja dan dimana saja. Korosi tidak dapat dicegah akan tetapi laju korosinya dapat diperlambat. Pipa berbahan dasar besi atau baja menjadi salah satu terget dari korosi. Terlebih lagi jika pipa tersebut berada di bawah media tanah maupun air laut yang mengadung kadar salinitas yang tinggi. Hal tersebut dapat merusak struktur permukaan pipa, membuat permukaan pipa semakin menipis, pipa menjadi bocor, dan timbulah kerugian bagi perusahaan. Oleh karena itu, dibutuhkan tindakan untuk melindungi dan memperlambat laju korosi dari sebuah material logam. Terdapat 2 metode, diantaranya: Sacrificial Anode Cathodic Protection (SACP) dan Impressed Current Cathodic Protection (ICCP). Penelitian ini membahas mengenai desain sistem monitoring arus pada metode impressed current cathodic protection serta menganalisis dampak penggunaan dari segi ekonomi dan teknik. Desain sistem monitoring arus ini menggunakan warna lampu sebagai indikator. Warna lampu hijau menunjukkan bahwa arus proteksi yang megalir pada pipeline sudah sesuai dengan standar, sedangkan warna kuning sebaliknya. Setelah melakukan analisis dari segi ekonomi dan teknik, diketahui bahwa penggunaan metode impressed current cathodic protection menjadi pilihan yang tepat sebagai metode untuk mendistribusikan gas daripada sacrificial anode cathodic protection. Hal tersebut dikarenakan metode impressed current cathodic protection lebih ekonomis sebesar Rp 337.051.724, lebih efisien dalam melindungi pipeline dengan struktur yang luas, dan juga dapat dikontrol & dimonitoring secara realtime. ==================================================================================================================== Corrosion becomes an event that cannot be avoided by every metal material. Corrosion can occur anytime and anywhere. Corrosion cannot be prevented but the rate of corrosion can be slowed. Pipelines made from iron or steel become one of the targets of corrosion. Moreover, if the pipe is under the media of land and sea water that contains high salinity levels. This can damage the surface structure of the pipe, such as: make the surface of the pipe thinner, the pipe will leak, and there will be economic loss for the company. Therefore, action is needed to protect and slow down the corrosion rate of a metal material. There are 2 methods, which is: Sacrificial Anode Cathodic Protection (SACP) and Impressed Current Cathodic Protection (ICCP). This study discusses about design monitoring system of gas pipeline for impressed current cathodic protection and analyzes the impact of the use in terms of techno-economic. The design of monitoring system uses the color of the lamp as an indicator. The color of the green light indicates that the protection current flowing to the pipe is in accordance with the standard, while the yellow color is vice versa. After analyzing techno-economic, it is known that the use of the impressed current cathodic protection method is the right choice as a method for distributing gas rather than sacrificial anode cathodic protection. That is because the impressed current cathodic protection method can saving the fund until Rp. 337.051.724, is more efficient in protecting pipeline for large structures, and can also be controlled & monitored in real time.
