Abstract

For 90% of world trade is carried by shipping industry. In Indonesia, highly concentrated goods movement are reported in Java and Sumatera which leads Tanjung Perak, Surabaya to become second largest ship terminal after Tanjung Priok, Jakarta. As the loading and unloading process is on call, any kinds of wastewater are continuously being discharged (sludge, oily sludge, blackwater and greywater). All wastewater if continuously discharged without any proper treatment is harmful to both human and aquatic environment. Especially in Indonesia and northern part of Java island where marine tourism is growing but in the other hand, also the home of largest ports. The purpose of this research is to design a fixed, compact discharge water treatment plant in one pilot international terminal, Terminal Petikemas Surabaya. The capacity of each discharge water receiver and treatment is determined according to ship’s arrival data. Based on the data analysis, the capacity of sludge receiver is 25 m3/day, oily bilge receiver for 200 m3/day, blackwater for 10 m3/day and greywater for 20 m3/day. Hereinafter, through the literature review of various kinds of wastewater treatment, a fixed and compact port-based discharge water treatment plant is designed by combining Membrane Bioreactor (MBR) for greywater, centrifugation for sludge, combination of ultrafiltration and reverse osmosis for oily bilge and Source Separation Sanitation (SSS) for blackwater where each effluent of the treatment can be used for one another. Furtheremore, an initial cost of the designed port-based discharge water treatment plant is conducted, resulting in total of IDR 22,487,086,876. The payback period (PBP) of the plant is 4 years.

Abstract

In the cylinder of conventional compression ignition engine, temperature distribution and stress variation set up in the entire piston due to the inherent nature of combustion. This project will investigate causes and effects of high gas pressure and temperature on marine two-stroke diesel engine piston. Investigation has shown that stress-related piston damages play a dominant role mainly due to mechanical and thermal stress or combination of both. The simulation parameters that will be considered in this report are piston material, combustion temperature and combustion pressure. In the present study, conventional marine two-stroke diesel engine piston will be modelled using Autodesk Inventor software. The working condition of the piston will be simulated based on the selected parameters using finite element analysis method to analyze the magnitude of mechanical stresses acting on the piston. The piston will be re-designed using a material superior to the conventional piston material and will be optimized by reducing the stresses acting on the piston. Two materials will be used in the analysis after which the results will be compared and the best will be proposed. The structure and stress analysis (mechanical, thermal and thermal-mechanical stress) of the design will be modelled using the software mentioned earlier.

Abstract

Along with technological development and the increase in human population, the electricity needs are increasing every year. However, 94% of power plant in Indonesia still using fossil fuels that are pollutant and non-renewable. In addition, NASA said that the earth's temperature had risen by 1°C since 1880 and the current carbon dioxide level was the highest in the last 650,000 years. Therefore, Indonesia need to improve, in fact Indonesia is one of the highest emission contributors in the world. Indonesia is not yet 100% electrified, there are still 2,519 villages without electricity. Gravitational Water Vortex Power Plant (GWVPP) which is a micro hydro-power plant may answer the problem, because it is an easy renewable energy to be made and utilized in the NIZ (not interconnected zones) region. This study will examine the changes in the number and shape of the blade, as well as the length of the chord, to know the effect on turbine power so that it can produce higher efficiency at GWVPP. Propeller turbine with a Gottingen 428 airfoil analyzed using Computational Fluid Dynamics (CFD) method. The results show that the number of blades and the length of the chord is inversely proportional to the efficiency of the turbine, and the shape of blade is more efficient when it’s twisted.

Abstract

The need for dredgers for the shallow water in the sea with a very high level of siltation on the coast of Indonesia is a factor worth considering. For example, coastal areas in Ujung Pangkah sub-district, Gresik district, East Java province. The choice of the area is due to the many institutions and corporations that are back and forth utilizing these waterways. But the main obstacle to making a Cutter Suction Dredger (CSD) is almost all the equipment needed is imported, for example, the main equipment is the cutter head. Therefore looking at the needs, economics and technology factors, this paper will discuss the cutter head design. Available data is a request from the owner, 40KW power cutter head; 1000mm cutter diameter; 30rpm rotation. The force distribution given 5950 N is in accordance with the dredging condition which is to have a strong material tension to be estimated to work at a relatively Soft density of <100 Mpa and Medium around 100Mpa - 170Mpa. The expected results of this design are to obtain a proportional design before the production process and to function at a minimum according to specifications. The usefulness of this design really hopes to be followed up to the production stage and can be applied.
