Abstract
Analisa tentang ketahanan mesin pendingin FPSO dari korosi yang terjadi dikarenakan bakteri dan alga microfouling dengan metode Impressed Current Anti Fouling (ICAF). Ketahanan yang dibuktikan dengan melakukan penelitian di laboratorium dengan menggabungkan kedua mikroorganisme dalam satu reaktor yang nantinya akan dipasangkan sistem ICAF. Material yang digunakan sebagai representatif dari mesin pendingin FPSO adalah Baja HSLA A36 sebagai katoda dan Tembaga (Cu) sebagai Anoda yang digunakan. Bakteri dalam penelitian adalah Pseudomonas Flurescens dan Mikroalga adalah Chlorella Vulgaris. Variasi Kuat arus 0.3, 0.5, dan 1 A. Waktu Uji 3, 5, dan 10 menit, serta perbandingan jumlah Bakteri dan Alga di masukkan dalam penelitian 75%:25%, 50%:50%, 25%:75% untuk mengetahui seberapa akurat hasil dari eksperimen. Setelah pengujian, Bakteri dan Alga yang tersisa dalam reaktor dihitung didapatkan waktu yang paling efektif dalam membunuh mikroalga Chlorella Vulgaris adalah 10 menit dengan presentase mikroorganisme terbunuh 100 % pada konsentrasi perbandingan 50 % dan 25 % mikroalga. Dan waktu yang paling efektif dalam membunuh bakteri Pseudomonas Fluorescens adalah 10 menit dengan presentase mikroorganisme terbunuh 99,97 % pada konsentrasi perbandingan terkecil 25 % bakteri dalam 1 A. Sehingga dapat dikatakan bahwa jenis biofouling yang tidak dapat bertahan adalah mikroalga Chlorella vulgaris dengan persentase kematian jumlah sel sebesar 97,72%.

This final project will discuss about the resistance of the FPSO cooling engine from corrosion that occurs due to bacteria and algae microfouling with the Impressed Current Anti Fouling (ICAF) method. The durability is proven by conducting research in the laboratory by combining the two microorganisms in one reactor which will be installed by the ICAF system. The material used as a representative of the FPSO cooling machine is HSLA A36 Steel as the cathode and Copper (Cu) as the Anode used. The bacteria in the study were Pseudomonas Flurescens and Microalgae were Chlorella Vulgaris. Current strength variations of 0.3, 0.5, and 1 A. Test time 3, 5, and 10 minutes, as well as the ratio of the number of bacteria and algae included in the study 75%: 25%, 50%: 50%, 25%: 75% to find out how accurate the results of the experiment are. After testing, the remaining bacteria and algae in the reactor were calculated to obtain the most effective time in killing microalgae Chlorella Vulgaris is 10 minutes with the percentage of microorganisms killed 100% at a concentration ratio of 50% and 25% microalgae. And the most effective time in killing Pseudomonas Fluorescens bacteria is 10 minutes with the percentage of microorganisms killed 99.97% at the lowest concentration ratio of 25% of bacteria in 1 A. So it can be said that the type of biofouling that cannot survive is Chlorella vulgaris microalgae with the percentage of number of deaths cell 97.72%.
