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.

Abstract

The rate of population growth which is relatively rapidly increasing in Indonesia, will require increased fuel. The depletion of the availability of fossil fuels causes the search for the other natural resources needed to become a renewable energy source. One of the significant changes today is microalgae. The application of the algal aquaculture system has been widely applied in the world. The media used in cultivation also varies, one of which is wastewater. The composition of biodiesel energy in Indonesia is increasing and is starting to become the people's choice. Indonesia, which is rich in natural resources, especially the high biodiversity of microalgae, causes microalgae's potential use to be very high. Many studies report the explosion of algal participation in many parts of Indonesia. Research concerning the cultivation of microalgae has been widely successful in Indonesia. The use of microalgae is already available in the field with domestic water treatment applications. The conversion of microalgae into biodiesel also successfully met the requirements of SNI 04-7182-2006.

Abstract

During the COVID-19 pandemic, the use of masks is an obligation for everyone to maintain the transmission of the virus to fellow humans. Public places such as stations are one of the locations that may produce single-use masks as personal protective equipment waste. This study aimed to plan the most appropriate type of infectious waste container for disposable masks. Storage with the addition of ultraviolet lamp technology is one way to increase virus removal efficiency compared with no further processing. In this study, it was estimated that the most appropriate container volume is with a capacity of 50 L per station. The collection must be done every 24 hours; the estimated cost for one container can reach IDR 1,988,900. This planning can reduce the amount of mask waste used for the environment and reduce the burden applied to these places at the end.

Abstract

The COVID-19 pandemic is a global outbreak that also changes the generation of medical waste in hospital. The increasing number of people infected with the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) virus indirectly requires the management of infectious waste from patients to be safe and not have the potential to spread. The purpose of this study was to analyze the medical waste management in a hospital located in Jakarta City, Indonesia. This study employed direct observation and used secondary data in the analysis. Meanwhile, to determine the effect of the population infected with SARS-Cov-2 on medical generation, One Way ANOVA analysis was used. Data from May, 2020 showed that medical waste generation increased from 25.6 kg/month to 192.3 kg/month. The ANOVA significance test showed a value of 0.013; this indicates that the number of the infected population significantly affects the generation of medical waste. Medical waste that found during a pandemic becomes more complex, including hazmat clothes, masks, gloves, medical headgear, used bandages, injection and infusion equipment, eating and drinking utensils for patients exposed to COVID-19, and used swab and rapid test equipment.

Abstract

Health facilities such as hospitals produce medical waste and non-medical waste. Improper management of medical waste can cause the spread of infectious nature, especially during the Covid-19 pandemic. Therefore, management at the source, such as minimization and containment, is important and must be evaluated. This study evaluates hospital medical waste management based on minimization and containment efforts. This research was conducted by direct observation and literature review. The findings on minimization efforts are following regulations such as reducing the use of materials containing hazardous and toxic materials if there is a choice, avoiding accumulation and expiration of the procurement of chemicals and pharmaceuticals, and separating non-medical and medical waste according to the waste category. The container also meets the standard where the container is equipped with a cover and is made of puncture-resistant material. The containers are also equipped with bags and symbols according to the characteristics of the waste with internal transportation at least once a day or when the container has been filled. Garbage officers prepare medical waste handover documents. Transportation from the production source to the temporary shelter (TPS) uses a yellow trolley with a biohazard symbol, tightly closed with a predetermined route, and cleaning and disinfection are carried out on the trolleys that are used every day.

Abstract

Small scale business / Usaha Skala Kecil (USK) X currently does not have a batik wastewater treatment unit. This condition causes the possibility of contamination to water bodies. USK X wastewater treatment applications' planning needs to be carried out sustainably, namely by reusing water. The process units needed in this planning are the sequencing batch reactor (SBR) and constructed wetlands. The effluent of textile wastewater with this system for parameters BOD, COD, TSS, sulfide, total oil & fat, and color were 0.13 mg/L; 106.5 mg/L; 2.4 mg/L; 0.036 mg/L; 0.07 mg/L; and 90.67 PtCo, respectively. The dimensions of the SBR unit required are 0.75 x 0.6 x 1 m. Modification of the SBR unit uses an ozone generator to produce ozone gas which functions as oxidation of organic pollutants and colors in batik waste. After processing in the SBR unit, it is carried out using a constructed wetland with 2.56 m2.

Abstract

Refuse derived fuel (RDF) is an environmentally friendly renewable fuel developed to reduce waste generation. RDF can consist of various kinds of waste such as paper and gardens. One of the critical parameters is the chemical element and calorific value. The purpose of this study was to determine the potential for waste reduction and the relationship of ultimate longevity in RDF to the calorific value. This study's paper and garden waste mixture were P0 (100% paper), P25 (75% paper and 25% garden), P50 (50% paper and 50% garden), P75 (25% paper and 75% garden), and P100 (100% garden). The calorific value of the mixture can reach 3.6-5.2 kWh/kg. Simultaneously the relationship of ultimate elements nitrogen (N), hydrogen (H), oxygen (O), and ash affects the heating value of RDF. Sampling the application in Depok City can reduce waste by 6.67%, with the potential for electrical energy from paper and garden wastes of 358,903.8 kWh and 48,681 kWh, respectively. This shows that this energy waste can supply 0.1% of the total daily electricity demand in Depok City.

Abstract

Central Java is one of the regions in Indonesia with a lot of water resources that must be appropriately managed. In addition, metal content in water bodies in Central Java must now be assessed to prevent health impacts that may be measurable. One of the methods to analyze the management of water bodies is the water quality index method. This study aimed to examine the water quality index due to metal contamination in water bodies in Central Java. Metal measurements were carried out using the AAS (Atomic Absorption Spectrophotometry) method. The value of the water quality index using the water quality index method for waters in Central Java in 2015-2018 was categorized to mild to moderately polluted, and only 2 locations were measured as heavily polluted. Two areas that are included in the heavily polluted category were the waters of Bulakan and Bojonegoro in 2016. To determine the cause of why the water quality index value being classified as moderately polluted and lightly polluted, we must look at the metal parameters that contribute the most to the index value. These parameters can be initial information on the pollutant source that causes pollution.
