ABSTRAK Pada penelitian ini dilakukan analisa ekonomis pemakaian anoda dengan metode sacrificial anode cathodic protection pada pipa API 5L gr. X52. Penelitian ini dilakukan dengan tujuan untuk merekomendasikan pemakaian jenis material anoda yang paling ekonomis pada lima jenis tanah yang sering dilalui pipa bawah tanah. Material pipa yang digunakan yaitu API 5L Gr. X-52 Schedule 60 (ketebalan 14,27 mm). Untuk penerapan di pipe line yaitu pada pipa bawah tanah yang dilindungi dengan coating 3LPE. Disini akan dilakukan pemvariasian terhadap resistivitas lingkungan, pemilihan material anoda, NPS pipa dan panjang pipeline. Penelitian ini akan menganalisa sejauh mana pengaruh variasi resistivitas lingkungan dan pemilihan tipe anoda terhadap perhitungan kebutuhan ekonomis pada metode sacrificial anode cathodic protection. Hasil penelitian ini dapat disimpulkan bahwa semakin kecil resistivitas lingkungan maka akan semakin kecil pula investasi yang harus dikeluarkan untuk pencegahan korosi metode sacrificial anode cathodic protection. Pada resistivitas 2000 ohm.cm adalah resistivitas yang memerlukan biaya investasi paling sedikit dibandingkan yang lainnya. Sedangkan anoda Alumunium (Al) adalah anoda yang memerlukan biaya paling sedikit jika dibandingkan dengan anoda Magnesium (Mg) dan Zinc (Zn). Kata kunci : sacrificial anode cathodic protection, resistivitas, anoda, NPS pipa, panjang pipeline ABSTRACT In this research, economic analysis used a anode with method sacrificial anode cathodic protection on the pipe API 5L gr. X52. This research was conducted with the objective to recommend the use of the type of anode material most economical on five types of land frequented by underground pipes. The pipe material used is API 5L Gr. X-52 Schedule 60 (thickness of 14.27 mm). For the application in the pipe line is in an underground pipe that is protected by coating 3LPE. The exercise variation for resistivity of the environment, the selection of anode material, outside pipe diameter and length of the pipeline. This study will analyze the extent to which the effect of variations in resistivity of the environment and selection of the type anode to the calculation of economic needs on a method sacrificial anode cathodic protection. The results of this study can be concluded that the smaller the resistivity of the environment it will be the smaller the investment that must be spent for corrosion prevention methods sacrificial anode cathodic protection. In 2000 ohm.cm resistivity is the resistivity requiring the least investment cost compared to others. While the anode aluminum (Al) is an anode that costs the least when compared with the anode Magnesium (Mg) and Zinc (Zn). Keywords: sacrificial anode cathodic protection, resistivity, anode, NPS pipe, length of pipeline
