Abstract

The Covid-19 outbreak that has spread throughout the world has resulted in a significant reduction in the number of users of the aircraft mode of transportation. The decline in the number of passengers was also experienced by PT. Lion Mentari Airlines or often known as Lion Air. This of course will have an impact on decreasing the company's revenue thereby reducing the Company's ability to pay for the rental costs of several of its aircraft. It is necessary to reschedule aircraft flights to increase aircraft optimization so that existing passenger services can be met with a smaller number of aircraft compared to before the Covid-19 pandemic. Flight scheduling at Lion Air is based on market demand, aircraft maintenance programs, aircraft availability per day and airport operating hours. This research will reschedule Lion Air flight paths on Boeing 737-800NG aircraft during the Covid-19 pandemic based on airport waiting time / ground time using the Hungarian method. The waiting time at Soekarno-Hatta airport before optimization was 5,895 minutes and there was a significant decrease in waiting time at Soekarno-Hatta airport after optimization, which was 18.78% or 1,107 minutes to 4,788 minutes, and by using the new schedule, Lion Air, which was originally operating 7 aircraft fleets for these flight routes can be optimized using only 6 aircraft fleets. Keywords: Operations Research, Assignment Problems, Hungarian Method, Boeing 737-800NG, Covid-19

Abstract

Plastic is one of the human needs in everyday life, as a place to wrap food and drinks, because plastic is practical, clean, and makes it easy for humans. Plastic is also an artificial inorganic material composed of chemicals that are quite harmful to the environment. To deal with plastic waste, a way is needed, to process the plastic waste into materials that are more useful and also have benefits for nature, one way is by recycling the plastic waste into fuel, namely fuel in the form of oil. By processing plastic waste into fuel oil, besides being able to reduce plastic waste, we can also save petroleum supplies in nature. In addition, the oil produced from this plastic also has a calorific value that is quite high on par with fossil fuels such as gasoline and diesel. The purpose of this research is to create a new tool size and create a new tool design from existing plastic waste processing equipment. The research method that the author uses is a field study method by analyzing existing waste processing equipment into liquid fuel and modifying the tool with Solidworks Software. In modifying the plastic waste processing equipment into liquid fuel, the first step is to modify the frame size which is more compact and not much free space and in modifying the design of the plastic waste processing equipment to become liquid fuel, the design is more attractive and elegant, while also prioritizing safety. Keyword: Oil, Design, Waste, Plastic, Solidworks
