Abstract
Korosi merupakan kerusakan yang terjadi secara alamiah. Salah satu metode pencegahan korosi adalah proteksi katodik menggunakan anoda korban. Salah satu standar yang biasa digunakan dalam desain proteksi katodik adalah DnVGL-RPB401. Selain itu, pengujian DnVGL-RPB401 dapat digunakan untuk mengukur kapasitas arus anoda. Pada penelitian kali ini, variasi bentuk anoda yang digunakan adalah bentuk anoda silinder, Balok dan kerucut. Variasi media elektrolit adalah larutan NaCl murni, larutan garam dapur dan air laut kenjeran. Pada media larutan NaCl murni, masing-masing bentuk anoda memiliki efisiensi yaitu 86%, 83%, dan 78%. Bentuk anoda selinder memiliki efisiensi paling tinggi karena jarak antara anoda dengan katoda yang sama pada anoda silinder sehingga distribusi rapat arusnya merata. Kemudian pada bentuk anoda yang silinder, masing-masing media elektrolit memiliki efisiensi yaitu 114%,86% dan 83%. Larutan garam dapur memiliki efisiensi paling tinggi karena sedikitnya kandungan NaCl yang merupakan penyebab korosi dan adanya kalium Iodida yang merupakan penghambat korosi.

Corrosion is a damage which occurs naturally. One method of corrosion prevention is cathodic protection using the sacrificial anoda. one standard commonly used in cathodic protection design is DnVGL-RPB401. In addition, DnVGL-RPB401 testing can be used to measure anoda current capacity. In this research, the variation of shape of the anode was the shape of a cylinder anode, rectangular prism and cone. The variation of electrolyte is pure NaCl solution, Kitchen Salt solution and Kenjeran sea water. In the electrolyte pure NaCl solution, each anode form has an efficiency of 86%, 83%, and 78% respectively. the cylindrical anode shape has the highest efficiency because the same distance between anode and cathode at the cylindrical anode.so that the current distribution is evenly distributed. Then in the form of cylindrical anodes, each electrolyte medium has an efficiency of 114%, 86% and 83% respectively. The salt solution has the highest efficiency because of the low content of NaCl which is the cause of corrosion and the presence of potassium Iodide which is a corrosion inhibitor
