Abstract

The maritime industry is one of the natural resources management industries that uses steel as its fundamental component. Much research and development have been conducted to increase the quality and life span of the steel used. ASTM A36 low-carbon steel is one of the steel variants commonly used on offshore structures because of its advantages. This research was conducted to achieve the additional effect of nano-alumina of 0%, 1,5% and 3% in the epoxy coating on adhesive strength, abrasive resistance and corrosion rate prediction. At pull-off testing, the highest adhesion strength was obtained at a mixed variation of 0% with a value of 7,7022 MPa. At the abrasion resistance test, the highest abrasion resistance was obtained at a mixed variation of 3% with a value of 16.7 grams. The lowest value of the corrosion rate prediction test was obtained on the mixed variation of 1.5% with a value of 0.005410622 mph.

Abstract

The pier is one of the primary means of sea transportation that continues to be developed to support equity activities and advance the community's economy. Bali is one of the main tourist destinations in Indonesia. The construction of the Sanur Floating Pier will create good connectivity between regions in Bali, which can become an additional tourist destination so that tourists can vacation longer in Bali. The purpose of this study was to determine the strength of the floating jetty structure through an analysis of the loading received by the structure and the resistance of the piles so that they can carry out designs related to the installation of strong and safe floating dock piles. In the analysis process, the author uses the help of Plaxis V.8.6 software to model the soil and AutoCAD 2018 as a support system in making the floating dock pile installation layout. The analysis results show that the floating dock can accept the forces acting on the structure. The UE RPD 250 fender and the T-Head MT 20 type bollard are the right choices. The pile has a lateral force value (H) of 1907 kg with a deflection of 0.19 mm. The greater the number of piles installed on the floating pier, the stronger the structure is evidenced by the smaller pile settlement due to soil changes.
