Abstract

Indonesia is no longer known as an oil exporter country but Indonesia has a large deposit of natural gas. This situation will bring the conversion from using fuel oil to gas. It will also support IMO Regulation such as MARPOL 73/78 Annex VI Tier III which was stringent in the regulation to bring the world to achieve near zero emission level. One of the methods to comply with IMO tier III is using gas as a fuel. Therefore, the ship efficiency can be overcome by two aspects simultaneously, cheaper and cleaner gas as marine engine fuel. In this paper, LNG as fuel will be applied to 100 TEUs Container Carrier which is consider several technical aspects when the existing ship is modified so that natural gas can be used safely and well. Things to consider in this LNG re-design are; the volume of tank, bunkering station system, and the Gas Valve Unit (GVU). In addition, this design will also analyze the costs required to modify the vessel so that it can use dual fuel (MDO and LNG) as well as cost comparison when using single fuel (MDO).

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 dredging of the canal water intake at PLTGU Grati is an effort to maintain the depth of the reduced canal due to sedimentation. The dredging process itself uses a cutter suction dredger. To distribute mud or slurry (a mixture of water and sand) result of dredging to dumping area of PLTGU Grati using HDPE (high-density polyethylene), as pipe material, hence pipe does not wear due to corrosion but erosion. Basically, erosion is caused by impact of solid particle (sand) which is suspended inflow (multiphase) on a solid wall boundary. Wear caused by erosion itself is recognized as one of the problems in some industries that distribute slurry in their process. This research thesis analyzes and predicts the rate of erosion occurring in HDPE pipes that are transported slurry from the sedimentation dredging in PLTGU Grati using CFD (computational fluid dynamic) method. Variations of slurry concentration, impact angle, particle diameter and velocity of the slurry has been be performed to determine the effect on the rate of erosion. The results of this research thesis showed that the concentration of slurry, impact angel, diameter of particle and the concentration of the slurry were directly proportional to the rate of erosion on the HDPE pipe.

Abstract

Flettner rotor is a technology that utilizes the natural wind to help the oncoming vessel. The working principle of the flettner rotor corresponds to the theory of magnus effect, in which the force arises due to the difference in pressure between the two sides of the flettner rotor. In this research the simulated flettner rotor has a diameter of 3 meters with a height of 18 meters. Simulations were performed 16 times with variations performed on rotation of rotor (0, 100, 300, and 500 rpm) and wind speed (5, 10, 15, and 20 knots). Flettner rotor analysis is done by computational fluid dynamic method. CFD results state that the largest coefficient lift value is on the flettner rotor with rotation 500 rpm with wind speed 20 knots that is equal to 91,13. While in its use of 4000 DWT container vessel, flettner rotor is more work at the speed of vessel 10 knot with rotation speed of flettner rotor 500 rpm and wind speed 5 knot that is equal to 17,438% from force that must be expended to move ship.
