The waste of milkfish scales and tiger shrimp shells is extracted into chitin through deproteination and demineralization processes. Chitin is synthesized into chitosan through deacetylation process. The yield of milkfish scales chitosan was 31,81%, while the yield of tiger shrimp chitosan was 67,16%. Corrosion rate testing using the weight loss method then calculates the inhibition efficiency of each inhibitor. Soaking the test specimens was carried out for 4 weeks with measurements of weight, pH value and salinity each week. The concentrations used were 0 ppm as negative control, 60 ppm, 500 ppm and 1000 ppm for chitosan inhibitor and 1000 ppm sodium nitrite as positive control. The optimum inhibition efficiency of milkfish scales chitosan is 48,9% at a concentration of 60 ppm with a soaking time of 3 weeks. The optimum inhibition efficiency of tiger shrimp shell chitosan is 57,7% at a concentration of 500 ppm with a soaking time of 1 week.

This research uses research design complete random design (RAL) with three repetitions. Local sea cucumber methanol extract (Phyllophorus sp.) contains bioactive compounds such as saponins, alkaloids, tannins, steroids and phenolics. Methanol Extract local sea cucumber (Phyllophorus sp.) affects the antifouling rate by reducing the Nerita sp. macrofouler paste rate with increasing concentration.

This means the concentration of the extract sea cucumber (Phyllophorus sp.) is deadly 50% of all biota test at a concentration of 185.18 mg/ml. Based on antifouling rate analysis and regaining rate it is known that the concentration of the most effective that can be used as an antifouling is a concentration of 75 mg/ml.
