Pengaruh Penggunaan Minyak Sebagai Bahan Pelapis Terhadap Pertumbuhan Biofouling Pada Kayu Non-klas BKI Sebagai Upaya Pengawetan Konstruksi Kapal Kayu
ABSTRACT
Wood is a medium that can be easily affixed by destructive organisms. Destructive
organisms that can affect wood resistance are commonly called Biofouling, one of
the countermeasures commonly used by fishing communities in traditional
shipbuilding is to use oil (oil and diesel). The purpose of this study was to
determine the resistance of BKI non-class wood to biofouling attacks after being
treated with oil coating (oil and diesel) which refers to the SNI 01-7207-2006
standard. This research was conducted from September to December 2019, by
immersing non-BKI-class wood in Dumai waters. Based on the results obtained
during this study, it can be concluded that the immersion time affects the weight of
the test specimen, this is evidenced by the weight gain that occurs with each lift.
The highest density of barnacles was found in wood cuttings in the untreated test
specimens, starting from the fourth to the last lifting, the density of barnacles on
the wood was always constant, namely 160 ind/m2. BKI non-grade wood has a
low attack rate against biofouling, so it can be used in parts of the ship that are
vulnerable to biofouling and other impurities.
