Abstract

Indonesia is currently one of the countries in East Asia which produces around 50% of the world's coastal waste. Microplastics in Indonesian seawater range from 30 to 960 particles/liter. The purpose of this study was to determine the size, amount, type, and microplastic polymers present on Lambutoa Beach in Takalar Regency. This study uses quantitative methods to examine certain populations or samples. Quantitative research methods are used to examine populations or certain samples, data collection uses research measuring instruments, and data analysis is quantitative/statistical in nature, with the aim of testing and proving the hypotheses that have been made/defined. The stages carried out during the research process were sand sediment sampling, sand sediment sample processing, observation and identification of microplastic types, and testing using the FTIR tool. From the results of this study, it was found that there were 49 samples of microplastic waste with an average size of 1-5 mm. There are three types of microplastic contained in the sand sediments that have been tested, namely films, fragments, and foam. For the type of polymer that is most often found in testing sediment samples using the FTIR tool on microplastic samples, these are Other (Nylon) and PET (Polyethylene Terephthalate) polymers

Abstract

Abstract: Plates are a very important part of shipbuilding and offshore structures. The reinforced plate is used to withstand loads acting in the axial and bending directions. The structure of the deck or bottom plate exhibits buckling or yielding behavior. Thus, it is very important to analyze the ultimate bearing capacity of a plate structure subjected to compressive loads for safe ship structure design. The material configuration used is the most important aspect in the FPSO structure design criteria. Plates and stiffened plates experience local buckling due to the external load when the hull girder collapsed. The objective of the present study is to analyze the effect of flange and web thickness to the ultimate strength on the FPSO in terms of plate deformation located of the bottom and deck area under compression stages. In this study, the attached plate thickness is varied according to FPSO data and BKI Rule. The stiffened plates element located at the bottom and deck area are modelled by Tee-Bar and Angle-Bar element. The simply supported condition is applied to the model and the anon-liniear Finite Element Method is used for the analysis. The result obtained by NLFEM shows that under tension and compression, the stiffened plate of Tee-Bar model, the deformations are 1,75 mm and 1,8 mm respectively. While for Angle-Bar model the deformation are 12,4 mm and 13 mm under compressing respectively.
