In this study, environmental and economic examinations of Liquefied Natural Gas(LNG) investments are conducted. A year-long noon report data is received from a container ship and LNG conversion is performed. Savings from both the fuel expenses and the amount of the emissions are calculated and presented. To eliminate the fuel consumption uncertainties in future operation periods of the stated ship, different scenarios that simulate various fuel consumption statuses are created and analyzed within the Monte Carlo Simulation method. Lastly, calculations are made with two different time prices, approx. one and half year apart. As a result of the analyses, LNG can provide high environmental benefits since it reduces 99% for SOx, 95% for PM10, 95% for PM2.5, 41% for CO2, and 82% for NOx, respectively. It is also determined that LNG investment is highly sensitive to fuel prices. In addition, the LNG usage can be beneficial for maritime companies in terms of marine policies such as paying carbon tax based on the expanding European Union Emission Trade System to maritime business. Still, it needs supportive carbon reduction method to comply with the maritime decarbonization strategy. This study has great importance in that the economic analysis way presented is able to adapt any alternative fuel system conversion for the maritime industry.

作者： Nurul Athirah Mohamad Abdul Ghafar Nur Farhanah Zulkipli Rabi’Atul A.Mat Yusoff Arni Munirah Markom Moh yasin Sulaiman Wadi Harun School of Electrical Engineering College of EngineeringUniversiti Teknologi MARAShah Alam 40450Malaysia Department of Physics Faculty of Science and TechnologyAirlangga UniversitySurabayaIndonesia Department of Physics Faculty of ScienceUniversiti Teknologi MalaysiaSkudaiMalaysia Photonics Engineering Laboratory Department of Electrical EngineeringFaculty of EngineeringUniversity of MalayaKuala LumpurMalaysia

A lutetium oxide(lu_(2)O_(3)) film was proposed and demonstrated for Q-switching operation at 1.55 μm region. It was obtained by solving lu_(2)O_(3) powder into isopropyl alcohol and mixing the solution into polyvinyl alcohol(PVA) solution to form a composite precursor solution via stirring, sonicating, and centrifuging processes. The thin film was formed through a drop and dry process and a small piece of this film was integrated into erbium-doped fiber laser(EDFL) cavity to modulate the cavity loss via Q-switching mechanism for pulse generation. The Q-switched laser operated at 1 565 nm with the repetition rate of 75.26 k Hz as the pump power was raised to the maximum value of 145.83 m W. The maximum pulse energy of 41.85 n J was recorded at 145.83 m W pump power. The mode-locked pulse operated at 968.5 k Hz with a pulse width of 510 ns was also realized in an extended EDFL cavity. The simple and cost-effective laser should have various applications including material processing, sensing and biomedical areas.
