Abstract

Secara umum biofouling adalah penempelan dan pertumbuhan organisme pada permukaan benda atau material yang terbenam di laut. Biofouling yang berukuran mikroskopis disebut dengan microfouling, di mana microfouling ini berperan sebagai perintis bagi organisme penempel berikutnya yang umumnya berukuran lebih besar (macrofouling). Pengendalian biofouling selama ini menggunakan bahan kimia pada cat antifouling. Penggunaan tributyltin–polishing copolymer paints (TBT – SPC cat) cat yang mengandung TBT memiliki efek buruk pada organisme laut non target. Penelitian ini menggunakan debu tembakau, yang merupakan limbah yang dihasilkan selama proses perajangan daun tembakau. Tujuan penelitian ini adalah untuk mengetahui potensi ekstrak debu tembakau sebagai anti microfouling. Hasil penelitian menunjukkan ekstrak debu tembakau (Nicotiana tabacum) berpotensi sebagai anti microfouling. Konsentrasi ekstrak debu tembakau paling efektif untuk dapat diterapkan menjadi anti microfouling adalah konsentrasi 40% dan isolat 3 dan 4 merupakan jenis isolat bakteri yang paling efektif untuk dihambat pertumbuhannya menggunakan ekstrak debu tembakau ============================================================================================== Generally, biofouling is defined as organisms’ attachment and growth in the surface of material that was soaked in the ocean. Microscopic biofouling is called microfouling, where it plays the role as a pioneer before eventually bigger organisms will take its place (macrofouling). To date, biofouling is being controlled by using chemical ingredients in antifouling paint. The usage of tributyltin–polishing copolymer paints (TBT – SPC cat) in the paint is causing damages towards the nontarget organisms in the ocean. This research is conducted using tobacco dust, which was the by-product of tobacco chopping. The purpose of this research is to identify the potential of tobacco dust extract as antifouling material. The result of the conducted research, it is known that tobacco dust has potency as anti microfouling. Tobacco dust extract with concentration rate of 40% is the most effective concentration as antimicrofouling material and isolate type 3 and 4 are the most effective bacterial isolates to inhibited by tobacco dust extract
