Harvesting marine microalgae Tetraselmis sp. using cellulose acetate membrane.

This study presents the development and application of a cellulose acetate phase-inversion membrane for the efficient harvesting of Tetraselmis sp., a promising alternative for aquaculture feedstock. Once fabricated, the cellulose acetate membrane was characterized, and its performance was evaluated through the filtration of Tetraselmis sp.

The role of energy consumption and economic growth on the ecological environment in ASEAN countries.

Currently, environmental degradation has become a global issue that needs to address frequently and also needs the attention of recent studies and regulators. Therefore, the present research examines the impact of energy consumption such as fossil fuel energy use, electric power use, and energy import along with economic growth on the ecological environment of ASEAN countries. The current study has gathered secondary data from world development indicators (WDI) from 1989 to 2019.

The dynamics of circulating SARS-CoV-2 lineages in Bogor and surrounding areas reflect variant shifting during the first and second waves of COVID-19 in Indonesia.

Background: Indonesia is one of the Southeast Asian countries with high case numbers of COVID-19 with up to 4.2 million confirmed cases by 29 October 2021. Understanding the genome of SARS-CoV-2 is crucial for delivering public health intervention as certain variants may have different attributes that can potentially affect their transmissibility, as well as the performance of diagnostics, vaccines, and therapeutics.
