Abstract
Pelabuhan Penyeberangan Bolok merupakan pintu gerbang utama bagi kendaraan yang menuju maupun dari Kota Kupang. Pelabuhan Penyeberangan Bolok mempunyai tiga dermaga yaitu Dermaga 1, Dermaga 2, dan Dermaga Sementara. Sebagai salah satu bangunan yang berada di lingkungan laut (onshore structure), dermaga juga tidak lepas dari permasalahan adanya korosi. Tiang-tiang pancang terbuat dari baja sehingga rentan terkena korosi. Selama ini penanganan korosi di tiang pancang dermaga Pelabuhan Bolok menggunakan pelapisan (coating), namun metode ini kurang efektif karena masih ditemukan adanya korosi. Ada beberapa alternatif penanggulangan korosi yang penggunaannya disesuaikan dengan tempat serta jenis lingkungan yang korosif. Alternatif tersebut antara lain adalah memasang selimut beton atau dengan pemasangan proteksi katodik. Pada penelitian ini dilakukan analisis untuk mengetahui metode yang paling efektif dan ekonomis untuk penanggulangan korosi pada dermaga dengan melakukan perbandingan antara selimut beton dengan proteksi katodik anoda korban dan proteksi katodik arus paksa. Dari segi teknis, selimut beton hanya bisa untuk proteksi daerah splash zone sedangkan SACP dan ICCP bisa memproteksi daerah dibawah splash zone. Hasil analisa ekonomis menujukkan bahwa biaya yang dibutuhkan selama design life 20 tahun untuk selimut beton Rp. 2.642.851.634, SACP sebesar Rp.1.443.209.157,04, ICCP Rp.3.932.495.044. Sehingga alternatif penanganan yang tepat dan efisien adalah metode sacrificial anode cathodic protection.
======================================================================== Bolok Crossing Port is the main gateway for vehicles heading to and from the city of Kupang. Bolok Ferry Port has three piers, namely Pier 1, Pier 2, and Temporary Pier. As one of the buildings in the marine environment (onshore structure), the pier is also not free from the problem of corrosion. Stakes are made of steel so they are prone to corrosion. So far the corrosion handling at the Bolok Port pile uses coating, but this method is less effective because corrosion is still found. There are several alternatives to corrosion prevention that are adapted to places and types of corrosive environments. These alternatives include installing a concrete blanket or by installing cathodic protection. In this study an analysis was carried out to determine the most effective and economical method for corrosion prevention on the dock by comparing the concrete blanket with sacrificial cathodic protection anode and forced current cathodic protection. From a technical perspective, concrete blankets can only be used to protect the splash zone area while the SACP and ICCP can protect areas under the splash zone. The results of the economic analysis show that the costs required for the design life of 20 years for concrete jackets are Rp. 2.642.851.634 , SACP amounting to Rp.1.443.209.157,04, ICCP Rp.3.932.495.044. So that the right and efficient alternative treatment is the method of sacrificial anode cathodic protection.
