Abstract
Pengembangan cat antifouling yang ramah lingkungan menjadi solusi untuk mengatasi pertumbuhan biofouling. Beberapa zat alami yang diketahui memiliki efek sebagai antifuling adalah alkaloid, tanin, terpenoid dan steroid. Daun Terminalia catappa diketahui memiliki kandungan zat alami tersebut, sehingga dimungkinkan dapat menjadi alternatif bahan antifouling. Penelitian ini bertujuan untuk mengetahui apakah bahan alami daun T. catappa dapat digunakan sebagai bahan cat antifouling. Ekstrasi zat alami dari daun T.catappa dilakukan dengan cara maserasi. Hasil ekstraksi daun T. catappa dibagi menjadi lima macam konsentrasi kemudian ditambahkan kedalam cat finising sebagai bahan antifouling. Plat baja kemudian direndam selama 28 hari dengan kedalaman 30cm dari permukaan laut. Parameter yang diamati adalah biomassa biofouling dan luasan penempelan biofouling. Perbedaan biomassa dan luasan penempelan sebagai pengaruh dari konsentrasi ekstrak dianalisis menggunakan ANOVA (Analysis of Variance) One Way pada taraf kepercayaan 95% dan Tukey’s HSD Test untuk uji lanjutan. Hubungan antara biomasssa biofouling dan luasan penempelan biofouling dianalasis dengan uji regresi linear. Uji skrining fitokimia menunjukkan ekstrak daun T. catappa memiliki senyawa alkaloid, tannin, terpenoid, dan steroid. Hasil penelitian menunjukkan bahwa ekstrak daun T. catappa memberikan pengaruh yang signifikan (p<0,05) terhadap luasan penempelan dan biomassa biofouling. Luasan penempelan memiliki pengaruh signifikan terhadap biomassa biofouling (p<0,005)

The development of an environmentally friendly antifouling paints as solution to address the growth of biofouling. Some natural substances known to have effect as antifuling are alkaloids, tannins, terpenoids, and steroids. T. catappa leaves contain that substances, so it is possible to be an alternative antifouling materials. This study aims to determine whether natural materials from T. catappa leaves can be used as an antifouling paint. Extraction of natural substances from the leaves T.catappa done by maceration. The extract of the T. catappa leaves divided into five kinds of concentrations and then added to finishing paint as antifouling material. Test plate is then immersed for 28 days at a depth of 30 cm from the sea surface. Parameters measured were biofouling biomass and biofouling coverage attachment area. Differences in biomass and the extent of adhesion as the effect of the extract concentration analyzed using ANOVA (Analysis of Variance) One Way at a level of 95% and Tukey's HSD Test for further tests. The relation between biofouling biomass and biofouling coverage attachment area are tested with a linear regression. The phytochemical screening test showed that T. catappa leaf extract had alkaloid, tannin, terpenoid, and steroid compounds. The results showed that T. catappa leaf extract gave significant effect (p <0,005) to the biofouling coverage attachment area and biomass. The coverage attachment area have significant influence on biomass biofouling (p <0.005)
