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
