Population Interactions

One of the global environmental problems of our time is the reduction of biological diversity — the extinction of species or individual subspecies of animals. The aim of this work is to develop a generalized deterministic model with discrete time, designed to analyze the nature and mechanisms of the dynamics of the number of biological populations characterized by the presence of a complex age structure.

Asean Country

Microplastic research is currently an exciting trend along with global environmental problems. The purpose of this study is to review the development of microplastic research in ASEAN. The researc uses a systematic review method by searching for the keyword “microplastic” and the name of the ASEAN country on the Google Scholar website, Science Direct, and other research paper provider websites. Papers reviewed in 2018 to August 2021 period were then classified based on the components analyzed. The results showed that based on the research location category, the majority of microplastic research was carried out in Vietnam (12/50 articles). The category of research object focused on marine organisms more than terrestrial organisms, the category of microplastic concentration varied because the microplastic sampling method was not standardized, the category of microplastic form dominated by the form of fiber; commonly found in coastal areas. The socio-economic category is not much related to the circular economy. To conclude, microplastic research still has opportunities, especially from a socio-economic perspective.
