Studi Eksperimen Laju Pertumbuhan Biofouling Pada Pelat Baja Dan Aluminium Dengan Lapisan Pelindung Lilin Dan Minyak Di Pantai Boom Banyuwangi

Indonesia is a maritime country with a tropical climate and has various biofouling species. The existence of fouling in a marine structure has a large impact on losses if it is not addressed immediately. Antifouling is needed to overcome the presence of fouling. Various development efforts to inhibit, prevent and eliminate biofouling continue to be made. Generally, the method used by the public is by using commercial antifoulant protective paints with heavy metal main components such as TBT (tri-n-butyl tin). However, currently various studies have proven that TBT compounds are not only toxic to biofouling biota but also harmful to other marine organisms. Further research is needed to find antifouling alternatives that do not contain toxic compounds and are more environmentally friendly. This study was designed to determine the growth rate of marine growth in steel and aluminum plate materials at Boom Banyuwangi Beach by using a protective coating in the form of oil and wax. From the results of the research designed, it can be analyzed the efficiency of using protective layers of oil and wax with steel and aluminum materials on the growth rate of marine growth according to the conditions of the waters of Boom Banyuwangi Beach. The use of oil protectors on steel and aluminum test specimens resulted in more efficient results in inhibiting the growth rate of biofouling than the use of wax protectors
