ABSTRACTThe presence of biofouling has an impact on the ship’s performance, which is reduced to require more fuel, in the end, it contributes significantly to cost increases. Biofilms provide a suitable substrate for the growth of microorganisms. Ship hull as a substrate for biofilms has many kinds of material. Steel, wood, laminated bamboo, and fiber are often used for ship hulls. Different material makes different characteristics of substrate for biofilms. The aim of this research is to determine the growth rate of biofouling in each shipbuilding material and to find out which vessel material is suitable for use in the Bali Strait. The experiment was located in Boom Marina, Banyuwangi. The materials used in this research are wood, laminated bamboo, and fiber. The daily growth rate (DGR) is calculated every week of observation. Wood had the most biofouling with a DGR of 2,646 g/day. Laminated bamboo had the least biofouling in this research after 2 months of immersion with a DGR of 0,086 g/day. Keywords: Biofouling, shipbuilding material, daily growth rate.

The Surabaya West Shipping Channel (APBS) is one of Indonesia's busiest sea transportation corridors.These waters serve as the entry and exit points for ships that dock or depart from Surabaya and Gresik ports.The proximity of the APBS to the river mouth causes sedimentation and siltation, which must be addressed.As support data for channel maintenance, information on the speed and direction of sea surface currents is essential.The purpose of this study is to provide a description of the dynamics of sea surface currents using hydrodynamic modeling simulations, as well as a comparison of their characteristics across seasons and locations. The main data, namely bathymetry and tides, were used to build the hydrodynamic model, which was validated using ADCP data measurements. Model simulation was conducted between March 2020 and February 2021.The simulation results explain the differences in patterns between transition season 1 and the east season, as well as transition season 2 and the west season. In the transition season 1 and the east season with the transition season 2 and the west season. The average speed of sea surface currents in the transition season 1 and the east season is 0.182 m/s to 0.427 m/s with the current direction from the south and southeast to the north and northwest. Whereas in the transition season 2 and the west season the average current speed reaches 0.183 m/s to 0.521 m/s in a direction from north and northwest to south and southeast . Model validation is sufficient, with an RMSE of 0.037 and a MAPE of 28.7%.
