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

PLTGU (Gas and Steam Power Plant) is a combination of gas power plant and steam power plant. PLTGU requires a cooling water systems during its operational life. The required amount of cooling water will increased along to increased power capacity of power plant. This project contains jetty extension study due to the addition of power capacity on thermal water dispersion at PLTGU Grati, Pasuruan. The results show using Delft3D hydrodynamic model, The alternative model showing quite good performance decreased temperature of cooling water on average 0.7975 oC at inlet canal. But it only need 2.5 oC increase of seawater temperature to decrease 0.33% efficiency, so it might change nothing to thermal power plant efficiency compared to the model result. Considering to the increasing risk of sedimentation rate, this alternative might be poor layout but further research needed. Still the best choice is on existing jetty design.

Abstract

Friction Stir Welding (FSW) is a solid-state welding technique that can produce high-quality joints without defects that commonly occur in liquid welding. However, FSW has limitations in underwater applications due to the friction between the tool and the material that causes a decrease in heat efficiency and shear force. To overcome this problem, this study proposes an underwater welding (UW) system with the FSW method on 316L stainless steel exposed to seawater. This UW-FSW system uses a high-speed rotating tool surrounded by an inert gas shroud to prevent direct contact between the tool and seawater. The aim of this study is to evaluate the performance of this UW-FSW system in terms of mechanical properties, microstructure, and corrosion resistance of 316L stainless steel joints. The results of this study show that the UW-FSW system can produce joints with better tensile strength, hardness, and corrosion resistance than conventional FSW. This is due to the rapid cooling, reduction of oxidation, and formation of a thicker passive layer on the joint surface. This study provides a contribution to the development of environmentally friendly and efficient underwater welding technology.

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.

Abstract

Abstract: The Port Singapore Authority (PSA) have a big role in sea transportation in Indonesia, whoever average 50 big vessels per day are tendered at the wharf of Singapore port for loading and unloading thousands of containers, so if Singapore port is congested for several hours the impact will make the crowded of sailing schedule for many vessels. Last week suddenly without any announcement Singapore port reported a problem with their port facilities and so their system, therefore many vessels were anchorages for several days about 4-6 days at the outer of the port for waiting time to tender. This accident makes the sea transport system by feeder service Indonesia-Singapore and vice versa re-scheduled. The impact for export-import activities from and to Indonesia was trouble because many can't call on time even omitted.  For several years or starting in 1985 Indonesian Shipping lines depend on Singapore port as an international hub port that will through cargoes to the destination port. They chose Singapore port because there are complete port facilities and a container system, nobody knows that crisis so will bome at Singapore as the biggest port in South East Asia. So now suggested to all of Indonesian shipping and Government to make a new big port as functions like Singapore port as an International hub port.

Abstract

Abstract: FPSO (Floating Storage Production and Offloading) is a floating structure that can be used as a location for production, storage or offloading of offshore oil and gas. Therefore, FPSO plays an important role in the exploration of oil fields in the deep sea. When operating, the FPSO will be exposed to environmental loads that can cause it to operate flexibly. To reduce movement response and maintain the FPSO in position, a mooring system is needed. The aim of this research is to analyze the numerical results of this experiment to find RAO (Response Amplitude Operator) free movement (free floating) as well as motion trajectory (surge & sway), motion characteristics, mooring line stress based on variations in the number of ropes used when moored with the direction of loading (heading) from different directions with time domain 250 seconds for each identification. This comparison analysis uses software Boundary Element Method (BEM) with data on FPSO dimensions, type of rope and mooring system, as well as environmental loads that influence the movement of the FPSO structure. The results of the analysis obtained show that in essence the use of the number of mooring lines will greatly influence the movement characteristics, the trajectory/flow of the floating structure and the tension of the mooring ropes. Where, the fewer the number of ropes used, the greater the movement and tension of the resulting rope and vice versa. Usually due to the mass of mooring line which is influenced by the number of ropes not being the same or smaller than displacement FPSO and is also influenced by environmental forces or loads which have repeated patterns over a certain time so that the amount used mooring line must also consider all aspects of the environment in its planning.
