The symposium provides a scientific platform for researchers and professionals to discuss ideas and current issues as well as to design the solutions in the areas of space science, ocean science, atmospheric science, , environmental science, material science, and other related disciplines.

1st Warmadewa International Conference on Science, Technology and Humanity will be an annual event hosted by Warmadewa Research Institution, Universitas Warmadewa. This year (2021), will be the first WICSTH will be held on 7 - 8 September 2021 at Auditorium Widya Sabha, Universitas Warmadewa Denpasar-Bali, Indonesia. In the direction of a new life order during pandemic COVID-19, Science, technology and humanity especially in ecotourism is a crucial topic to address, this is a momentum to bring together various critical views and thoughts from various fields of science related to strategies that can be done in developing and solving ecotourism resilience during pandemic COVID-19 in Science, technology and humanity study.The conference invites delegates from across Indonesian and is usually attended by more than 100 participants from university academics, researchers, practitioners, and professionals across a wide range of industries.

This book consists of selected papers from the 2022 4th International Conference on Environment Sciences and Renewable Energy, which was held as a fully virtual conference during May 27–29, 2022. The book overviews the latest progress in environmental and energy technologies with a specific focus on wind turbines and hydrogen production. In the field of environmental science, wastewater treatment, air pollution abatement, solid waste treatment, and general policy recommendations are discussed. Technology advances, especially in wastewater nutrients and micropollutant removal, are covered. In policy measures, cost allocations, optimum recycling strategies, and environmental footprint allocations of different environmental technologies are included. In the field of renewable energy, several hot topics, including solar cells, offshore floating wind turbines, and renewable energy resource potentials in different regions are considered.
