ABSTRACT
Parangtritis Beach, Yogyakarta, Indonesia, is one of the most visited tourist destinations for domestic and international tourists. These tourists are required to carry out health protocols by wearing masks during the COVID-19 pandemic. The high number of visits is linear with the generation of waste in tourist areas. Marine debris is defined as any solid material that settles, dumps, or is dumped, dumped, or disposed of in the marine and coastal environment. Efficient management of marine debris is a coordinated strategic approach to dealing with problems and inefficient law enforcement to improve the preservation of the marine environment. This study aimed to analyze the composition, characteristics, and management of marine debris in the Parangtritis Beach area during the COVID-19 pandemic. The amount of waste generated during the pandemic was recorded at 0.9 kg/m2.day. Sampling is carried out using the line transect method. The composition of waste consists of PET, PE, other plastics, biodegradable organics, and masks, each of which is 17.86%, 32.54%, 6.85%, 37.61% and 5.14%. Due to the COVID-19 pandemic, mask waste has become waste that has a new category, namely infectious. The characteristics of marine debris other than organic biodegradable tend to have a high calorific value so that it is possible to be processed by thermal processes. Thermal gravimetric analysis (TGA) shows that Polyethylene Terephthalate (PET), (Polyethylene) PE, and mask waste can be decomposed at a temperature of 260-550°C. Organic waste has been managed by processing Black Soldier Fly (BSF), while plastic waste can be processed into handicraft products. In contrast, the remaining plastic waste and masks are processed by a thermal process to allow waste to energy. © 2022 Authors. All rights reserved.
ABSTRACT
The very high need for personal protective equipment (PPE) impacts the waste generated after using these tools. Therefore, to deal with mask waste during the COVID-19 pandemic, this study was carried out on the processing of mask waste using a thermal process and studied how the potential of this process was for the effectiveness of mask waste processing during the pandemic. This research was conducted on Honeymoon Beach by collecting data on mask waste generated during the pandemic, then measuring the waste proximate, ultimate, and calorific value and testing the thermal process using TGA and Piro GC-MS measurements. Most waste masks found on Honeymoon Beach are non-reusable masks, 94.74%, while reusable masks are 5.26%. The waste is then subjected to thermal processing and analysis using TGA and Piro GC-MS. Based on the data obtained, the thermal process can reduce the mass of non-reusable and reusable mask samples by 99.236% and 88.401%, respectively. The results of the Piro GC-MS analysis show that the lit mask waste will produce fragments of compounds that can be reused as fuel. The process is simple and easy and produces residues that can be reused to reduce environmental pollution due to waste generation during the COVID-19 pandemic.
ABSTRACT
The coronavirus disease 2019 (COVID-19) shifts the characteristics of municipal waste. This paper aims to provide an overview of trends, impacts, and management during the COVID-19 pandemic globally. The increase in the generation of plastic waste and infectious waste is a new challenge during the COVID-19 pandemic. It was found that the emergence of plastic waste due to the consumption of food delivery becomes an issue in several countries. Despite the increment of plastic waste generation, the mass layoffs contributed to the decrease in the total urban waste generation in general. In addition to plastic waste, a surge of infectious waste from health facilities and household waste originating from residents infected with the SARS-COV-2 virus was observed. This infectious wastewater potentially leads to environmental disturbances to the rivers and oceans. To tackle global environmental concerns, sustainable waste management is required especially in the development of biodegradable personal protective equipment. © 2022, Intelektual Pustaka Media Utama.

ABSTRACT
Ngudi Kamulyan is a domestic waste treatment facility which imply 3R (reduce, reuse, recycle) in Gajahmungkur District, Semarang City-Indonesia. This facility is already in status quo due to the lack of human resources and this Covid-19 pandemic. Therefore, this facility has chances to improve its services after the pandemic. The activation of this facility can reduce the number of mismanage waste and open burning incidents. Performance improvement planning is carried out based on the five aspects of waste management. This study was conducted using qualitative analysis and questionnaire survey to the neighbourhood leaders and facility officers. Community participation planning was done with activities focused on improving the 3R habit in the community. There is a need for continuous supervision from related parties, such as Gajahmungkur District Semarang City Government and the Environmental Agency of Semarang City. That supervision will be necessary to make the waste treatment facility and operational activities of 3R could run consistently.
