Abstract

Tiang pancang baja (steel piling) yang menopang Jetty-3 PT XYZ telah dilengkapi coating dan HDPE lining pada atmospheric zone, splash zone, dan tidal zone. Namun, hasil pemeriksaan visual mengindikasikan masih adanya korosi di beberapa titik, terutama pada permukaan pile yang terendam air laut. Temuan ini menandakan perlunya metode proteksi tambahan guna melindungi bagian pile yang belum terproteksi secara maksimal oleh kedua metode proteksi sebelumnya. Penelitian ini merancang sistem sacrificial anode cathodic protection (SACP) untuk 84 pile yang tersebar di jetty head platform, breasting dolphin, dan mooring dolphin. Perancangan menitikberatkan pada analisis yang ditinjau dari aspek teknis dan aspek ekonomis antara variasi anoda, meliputi material aluminium dan seng, serta tipe anoda, meliputi flush mounted, stand-off, dan bracelet. Variasi anoda yang akan digunakan dipilih melalui metode Weighted Product. Hasil analisis menunjukkan bahwa jumlah kebutuhan anoda dan estimasi biaya pemasangan anoda beragam tergantung spesifikasi dari variasi anoda, di mana dibutuhkan 84 anoda aluminium - flush mounted dengan biaya Rp1.314.000.000, 84 anoda aluminium - stand-off dengan biaya Rp1.330.000.000, 84 anoda aluminium - bracelet dengan biaya Rp1.343.000.000, 216 anoda seng - flush mounted dengan biaya Rp3.480.000.000, 192 anoda seng - stand-off dengan biaya Rp3.237.000.000, dan 216 anoda seng - bracelet dengan biaya Rp3.436.000.000. Berdasarkan metode Weighted Product, variasi anoda aluminium – flush mounted dipilih sebagai opsi terbaik untuk sistem sacrificial anode cathodic protection (SACP) pada pile Jetty-3 PT XYZ.

The steel piling supporting Jetty-3 of PT XYZ has been equipped with coating and HDPE lining in the atmospheric zone, splash zone, and tidal zone. However, visual inspection results indicate the presence of corrosion at several points, particularly on the pile surfaces submerged in seawater. This finding highlights the need for additional protection methods to safeguard the pile sections that are not adequately protected by the existing methods. This study designs a Sacrificial Anode Cathodic Protection (SACP) system for 84 piles distributed across the jetty head platform, breasting dolphin, and mooring dolphin. The design focuses on technical and economic analyses of anode variations, including aluminum and zinc materials, as well as anode types such as flush mounted, stand-off, and bracelet. The anode variations were selected using the Weighted Product method. The analysis results indicate that the required number of anodes and the estimated installation costs vary depending on the specifications of each anode variation, with 84 aluminum flush-mounted anodes costing Rp1.314.000.000, 84 aluminum stand-off anodes costing Rp1.330.000.000, 84 aluminum bracelet anodes costing Rp1.343.000.000, 216 zinc flush-mounted anodes costing Rp3.480.000.000, 192 zinc stand-off anodes costing Rp3.237.000.000, and 216 zinc bracelet anodes costing Rp3.436.000.000. Based on the Weighted Product method, the aluminum flush-mounted anode variation was selected as the best option for the Sacrificial Anode Cathodic Protection (SACP) system for the piles of Jetty-3 at PT XYZ.
