High-resolution ocean circulation models have increased our understanding of the movement and distribution of worldwide ocean currents, which were previously unknown and difficult to study. The metabolic expenditure data obtained through open-flow respirometric analysis was put into an energy budget context by comparing it to their available reserved energy in the body upon entering the swimming life phase. We modeled the dispersal range of green turtle hatchling from Chagar Hutang in various monsoon season using the particle-tracking program Ichthyop v3.2 and ocean surface current output from HYCOM (Hybrid Coordinate Ocean Model). The prediction distribution suggests that ocean current variability determines their movements into different dispersal areas. The simulated hatchlings are distributed north into the Gulf of Thailand during the Southwest monsoon, while during the Northeast monsoon, the simulated hatchlings travel south into the Java Sea. By quantifying hatchlings potential energy, they can swim a distance of 116 km and can last up to 7 days. Green turtle hatchlings from Chagar Hutang reached offshore water of Kelantan State and Terengganu waters near Tenggol Island on Day 7. These findings highlight areas of high priority for conservation, as habitat crucial for an endangered sea turtle species during a critical period of early development.

This research explores one of the most serious environmental threats to human health which is air pollution. The objective of this study is to examine the concentration of several air pollutants that has been affecting the atmosphere specifically in Southeast Asia after the emergence of the pandemic. Throughout this research, the air pollution concentration is monitored using several observation satellites such as NASA GIOVANNI, Ozone Monitoring Instrument (OMI), and MODIS-Aqua to see the difference in air quality before and after the lockdown was implemented in the selected specific area. The average mean for the studied year of each selected pollutant was also observed to see the pattern of the air quality after the pandemic. Thailand and other northern Southeast Asian nations bordering China were found to be the most affected by transboundary pollution, which was brought on by the climatological changes that all Southeast Asian countries experienced. In addition, most Southeast Asian nations are regarded as developing countries that rely significantly on power produced by fossil fuels and individual transportation. Consequently, it significantly worsens the air pollution in the area. This study is significant as it allows the government to regulate the air quality in a specific region and it is important to monitor the air pollution in the atmosphere as it has a substantial impact on human health as well as the environment. By conducting this study, it can be seen that there are major positive changes in air quality in Southeast Asia as it is the result of the lockdown and lack of human activities in each countr
