The performance of a material structure can be affected due to corrosion damage. Corrosion is a decrease in metal quality caused by electrochemical reactions between metals and their surrounding environment. One of the causes of corrosion is microalgae or called biocorrosion. Corrosion can cause failure of the pipe structure which causes the pipe to not operate properly. The purpose of the research was to determine the corrosion rate of ASTM A53 steel material with full annealing heat treatment and without heat treatment. Second research aim was to determine the biocorrosion with added of microalgae and without the addition of microalgae. Heat treatment and non-heat treatment materials were testing using the immersion corrosion test method, which was soaked in artificial seawater with a salinity of 35‰. Based on the results, the highest biocorrosion rate on non-heat treated materials with the addition of Chrorella vulgaris reached 0.2780 mpy. While the biocorrosion rate after full annealing treatment was 0.1434 mpy and the size of uniform corrosion and pitting decreased. The percentages reduction of biocorrosion rete was 46.58%. This indicates that the addition of Chlorella vulgaris can accelerate the corrosion rate and full annealing can inhibit the biocorrosion rate.

Fouling is an adverse problem for ship. Fouling itself is some kind of marine biota like shells, mussels, or barnacles, which grow and live on the surface of ship’s hull or inside the ship’s piping system. Many methods have been applied to prevent fouling. Impressed Current Anti Fouling (ICAF) was developed and applied as an alternative in mitigation of fouling. The aim of the research was to determine the effects of electrical current, duration time, salinity on Anadara granosa death in simple ICAF system. The simple ICAF reactor was operated in electric current of 1.5 A, and duration time (1,3,5,7 dan 9 h), variations of salinity (33 ‰, 35‰ and 37‰) and the size of shell (1-2 cm and 2-3 cm). Steel of AH36 has a role as a cathode, meanwhile pure copper (Cu) was an anode. The death of Anadara granosa was conducted using direct observation. The direct observation was carried out by opening the shells one by one. The death of mollusc can be confirmed by looking the response from the mollusc. If the mollusc showed no response when it was pierced, it indicated that the mollusc was dead. Besides that, there was white slime inside the mollusc. Based on the results, the death of Anadara granosa with shell size of 2-3 cm showed the highest percentage of 90% at electrical current of 1.5 A, duration time of 9 h, and salinity of 37 ‰. Meanwhile the smallest percentage of Anadara granosa death reached 10% at electrical current of 1.5 A, duration time of 7 h, and salinity of 33 ‰ for shell size of 1-2 cm. In conclusion, duration time and salinity were higher so that the death of Anadara granosa was higher too. Besides that, the small size of Anadara granosa was more resistant.
