Climate change and soil erosion are very associated with environmental defiance which affects the life sustainability of humans. However, the potency effects of both events in tropical regions are arduous to be estimated due to atmospheric conditions and unsustainable land use management. Therefore, several models can be used to predict the impacts of distinct climate scenarios on human and environmental relationships.

However, during the restriction period due to the COVID-19 outbreak, anthropogenic activities have been suspended, which clearly shows a good opportunity for a better environment. Therefore, we aimed to analyze the variation of AMD-associated water pollution in three main zones of the Chini Lake catchment area using Sentinel-2 data for the periods pre-movement control order (MCO), during MCO, and post-MCO from 2019 to 2021.

- Fuel contamination, primarily caused by microbial growth, poses a significant challenge during the handling and storage of biodiesel.
- The study analyzes microbial colonies in various fuel samples (diesel, biodiesel, and blends) stored in different environments over 90 days, revealing high contamination levels in all types.
- Findings indicate that blends such as B20 show increased bacterial diversity and growth, while neat biodiesel (B100) exhibits the highest contamination levels, with notable increases in acidity and water content over time.
Article Synopsis
- The study examines the spatial distribution and spread of COVID-19 during the first and second waves in South Sumatra, Indonesia, using GIS software for mapping.
- The research found that the highest infection rates were in densely populated areas like the Palembang district, while remote areas saw lower rates; the epidemic spread rapidly from August to December 2020.
- Key meteorological factors like air temperature, wind speed, and precipitation were significantly linked to higher spread rates in the second wave, providing insights for future control and prevention strategies.

View Article and Find Full Text PDFCOVID-19 pandemic is the global health crisis of our time. A recent study has found that the virus can remain viable in air for multiple hours, thus the spread of virus can be affected by wind conditions such as wind speed and direction. Therefore, this study aims to analyze the impact of wind conditions on COVID-19 pandemic in Jakarta, Indonesia.
