Covid-19 has a significant risk of spreading in urban areas because of the aglomeration of built-up areas and people. It frequently contains a mix of land uses and is accessible to urban amenities. Due to the area's extensive usage of mixed land uses, it is better able to provide internal urban services on its own. Greater use of area lockdown and social separation strategies could result from this situation. The most populous city in the province of Central Java, Surakarta, has a significant risk of contracting COVID-19. The purpose of this study is to evaluate the impact of density and levels of mixed land use on the Covid-19 distribution in Surakarta City.Population density is used to calculate density. The entropy index approach was used to measure the amount of mixed land use. It is a method for calculating the balance between each form of land use. The availability of current land use data being processed by the spatial analysis with the Arc GIS application provided help for the analysis. Additionally, it makes use of information on Covid-19 cases in relation to the general populace that is supplied by the Surakarta Municipality. The relationship between mixed land use and Covid-19 risk was analyzed using a linear regression approach. The study's findings indicated a minor influence between density and the spread of COVID-19. Meanwhile, the level of mixed land use does not influence the spread of the Covid-19 virus in Surakarta City.

The tourism sector is one of the sectors that has been negatively affected by the COVID-19 pandemic. Increased waste generation is a significant problem that tourist areas must face during the COVID-19 pandemic. Therefore, to reduce the impact, research was carried out on waste management before and during the pandemic in regional tourism areas, especially in the eastern part of Java and Bali. This study aims to analyze the changes and composition of waste and during the COVID-19 pandemic in tourist areas in the Eastern Tourism Areas of Java and Bali. Collecting, processing data, and statistical analysis carry out the research method. Based on the study results, the waste generation generated in eight eastern regencies of Java and Bali experienced a change between-5.67% to 1.82%. Plastic waste increased by 27.61% during the pandemic, while mask waste increased by 1.23% in one area. Waste management also changed from-0.011% to 1.821%. The analysis results using ANOVA showed that the COVID-19 pandemic significantly affected the amount of waste generated by the eight tourist areas, with the main contribution caused by an increase in mask waste. © 2023, Polskie Towarzystwo Inzynierii Ekologicznej (PTIE).

Waste in the archipelagic border area must be appropriately managed to maintain diplomatic relations. Indonesia's Riau Islands Province is an archipelagic region in Indonesia with limited solid waste infrastructure development. The capacity of the waste infrastructure depends on the rate of waste generation and is influenced by the socioeconomic conditions of the community. This study aims to study the model for estimating the rate of waste generation in the Riau Islands. This study uses data before and during the Covid-19 pandemic in 2019 and 2020. The estima-tion model uses a multiple linear regression model with independent variables such as gross regional domestic product, access sanitation, total population, and human development index. The fixed variable is the incidence of waste generation rate. During the pandemic Covid-19, the generation and composition of waste in the Riau Islands Archipelago did not experience significant changes, so the waste generation and composition characteristics are the same. However, the variable human development index (0.053) and the population (0.012) significantly increase the waste generation rate. The gross regional domestic product (0.017) negatively correlates, reducing the waste generation rate. The Riau Islands, which has an ocean area of 96%, is a source of life and significant to manage because the waste can be released into the ocean. Therefore, management from sources through policies considering the gross regional domestic product, total population, and human development index needs to be considered to reduce waste generation in the archipelago. © 2023, Polskie Towarzystwo Inzynierii Ekologicznej (PTIE).
