In vitro investigation on Pennisetum purpureum leaf extracts grown in Indonesia of phytochemical components, optical characteristics, and antioxidant-antibacterial activities.

Medicinal plants hold significant cultural significance and play a crucial role in the advancement of potentially safe drugs for the therapy of disease worldwide. Pennisetum purpureum or elephant grass has been used for traditional medications in Indonesia without understanding the phytochemicals of those plants. Herein, our report revolves around the qualitative and quantitative examination of phytochemical components, optical properties, antioxidants, and antibacterial assessments of solvent fractions derived from Pennisetum purpureum leaf.

Techno-economic analysis of natural gas distribution using a small-scale liquefied natural gas carrier.

The design of the gas distribution for small-demand power plants located on remote islands is logistically challenging. The use of small-scale liquefied natural gas (LNG) vessels can be an option for these logistic problems. This paper aims to conduct a techno-economic analysis of using small-scale LNG vessels for gas distribution to the power plants that are spread across different islands.

Indonesia medical students' knowledge, attitudes, and practices toward COVID-19.

Implementing health protocols and preventive measures are the only effective ways to suppress COVID-19 transmission before vaccines and antiviral drugs are developed. The implementation of health protocols and preventive measures are influenced by one's knowledge, attitudes, and practices (KAP) toward this pandemic. Medical students as candidates for healthcare workers and role models for the community should have a good KAP.

Evaluation of CO emissions and energy use with different container terminal layouts.

Sustainable development of container terminals is based on energy efficiency and reduction in CO emissions. This study estimated the energy consumption and CO emissions in container terminals according to their layouts. Energy consumption was calculated based on utility data as well as fuel and electricity consumptions for each container-handling equipment in the container terminal.

Study on the LNG distribution to mobile power plants utilizing small-scale LNG carriers.

In recent years, the use of small-scale liquefied natural gas (LNG) has grown alongside demand from industrial users of natural gas. Small-scale LNG is an alternative to the supply of natural gas to remote areas with a cost-effectiveness challenge. To address this challenge, five mobile power plants located in remote areas with limited depth of water level in western Indonesia are used here as a case study.
