Nabila Ardiana et al., International Journal of Advanced Trends in Computer Science and Engineering, 9(5), September - October 2020, 8364 - 8370 8364 ABSTRACT The use of public transportation such as train is the practical choice for the capital city people. The active gathering place for people causing waste, in this case, at the station. Various kinds of waste can be generated inside the station, such as wastewater, domestic-like waste, and hazardous waste. In the era of the COVID-19 pandemic, hazardous waste generation is the main focus not to infect humans. The purpose of this research is to examine the management of hazardous waste from the train station. This research uses secondary data from a hazardous waste inventory. The hazardous waste inventory results before the COVID-19 pandemic, hazardous waste generation is only 2.11 kg/day, and 2% are infectious characteristics. Considering that during the COVID-19 pandemic, domestic waste such as disposable masks, used gloves, tissue/cloth containing liquid/nasal and mouth droplets would fall into the category of being treated as infectious waste. Comparison with literature studies shows infectious waste generation at the train station can reach 1.93 - 12.5 L/day. Reservoirs of combustible hazardous solid waste can use used drums, combustible hazardous liquid waste can use HDPE plastic material, and hazardous toxic waste can use fiberglass. Infectious, hazardous waste was put into a container lined with yellow plastic bags with biohazard symbols and given disinfectants such as 0.5% chlorine, Lysol, and carbolic acid. Hazardous waste transportation can use a Stationary Container System (SCS), and officers must use personal protective equipment according to standards. Hazardous waste treatment can use an incinerator or autoclave. Key words : hazardous waste, solid waste, COVID-19, train station, mask, infectious 1. INTRODUCTION The train is one of the environment-friendly transportation services. The development of transport will be expected to continue to quite a high increase, so transportation would be a new problem if it does not consider the impact on the environment. It is making the developed country aware of the dangers and impacts of the use of transportations. As in the European Union, trains are an essential part of the goods and passengers’ transportation and consider its responsibility for environmental impacts and energy consumption involving the use, maintenance, and improvement of the transportation [1]. The number of vehicles is increasing every year, making the process of vehicle maintenance increasing. In line with the high demand for public transportation such as railways, it can increase the hazardous waste generation. One of the hazardous materials used is oil [2]. After used to lubricate the engine, oil then replaced periodically. This replacement is intended to lessen the damage of engine components that rub against each other in the engine because the oil that has been used contains refined metals from engine components. The number of vehicles is increasing, and cities and regions’ rapid development makes the hazardous waste generation increase. Besides the hazardous waste generation from vehicles, medical waste from transportation stations is also a new challenge. Early June 2020, WHO issued a recommendation for all people to use masks, healthy and sick people [3]. Even though big cities have implemented much work from home [4] [5] [6], there is still a large proportion of workers who have to work from the office. It causes the need for public transportation to remain a priority for most workers. So it is estimated that the generation of infectious waste from the station will still exist. This suggestion revisions the previous appeal that states that masks are only intended for sick people. This appeal was issued for the coronavirus’s current spread and can also be spread by people who have not been symptomatic and airborne. As a result, the use of masks and gloves will increase. The waste contained nasal, and mouth fluid/droplet has the potential to have infectious properties. For this reason, people are required to use cloth masks, which are recommended for only four hours. Therefore, there is a Challenges for Hazardous Waste Management Related to COVID-19 Pandemic at Train Station Nabila Ardiana 1 , I Wayan Koko Suryawan 2* , Betanti Ridhosari 3 1 Undergraduate Program of Environmental Engineering, Faculty of Infrastructure Planning, Universitas Pertamina, Jakarta, 12220, Indonesia 2* Department of Environmental Engineering, Faculty of Infrastructure Planning, Universitas Pertamina, Jakarta, 12220, Indonesia, i.suryawan@universitaspertamina.ac.id 3 Department of Environmental Engineering, Faculty of Infrastructure Planning, Universitas Pertamina, Jakarta, 12220, Indonesia ISSN 2278-3091 Volume 9, No.5, September - October 2020 International Journal of Advanced Trends in Computer Science and Engineering Available Online at http://www.warse.org/IJATCSE/static/pdf/file/ijatcse210952020.pdf https://doi.org/10.30534/ijatcse/2020/210952020
