Abstrakt: This present study has been designed to develop an Antifouling agent to minimize the attachment of fouling organisms on the submerged substratum. In order to analyze the leaf extracts of reputable species, such as Ipomoea pescaprae, (sand dune plants) and Sesuvium portulacastrum, Batis maritima (salt marsh), an attempt was undertaken. Methanolic extracts of three plants were screened for antifouling activity against six marine fouling bacteria (Proteus mirabilis, Proteus vulgaris, Pseudomonas sp., Vibrio sp., Staphylococcus aureus, Escherichia coli) using disc diffusion method where the methanolic extract of Ipomea pes caprae exhibited a maximum zone of inhibition (26mm) against Pseudomonas sp. Further, the minimum inhibitory concentration assay was performed to determine the lowest effective concentration to inhibit microbial growth. Hence, the result has suggested Ipomea pes-caprae has a maximum inhibitory percentage (51%) in a lower concentration (100µL) against E. coli. To detect the functional groups in three extracts, FTIR was carried out, where Amine, Secondary Alcohol, Alkane and Amine salt all are commonly present in these three samples. A field study has been designed to evaluate the antifouling efficiency of three samples, where the commercial paint was formulated using methanolic extracts from three different plants. Thus, resulted in Sample-1 (Ipomea pes-caprae) has good bioactivity towards fouling organisms and resulted in less percentage of fouling formation (Wood-10%, Aluminium-22% and Fiber sheet-26%) in this field study.
