Journal of Technology Renewal and Advanced Science (JTERAS) is a reference journal that aims to explore, develop and explain knowledge about engineering design and technology, so that practitioners and researchers are informed about current issues and best practices, and serves as a platform for the exchange of ideas, knowledge and expertise among technology researchers and practitioners. JTERAS is published by Gio Vani Publisher. Papers published in JETRAS are highly representative of the use of sustainable technologies in the design of products and services for tropical environments. Sustainable technologies have developed in various Asian countries that adhere to the principles of social, economic, and ecological sustainability and are grouped into the following themes: conventional and renewable energy, sustainable architecture, construction and the environment, advanced materials and manufacturing technologies, efficiency and improvement productivity. The application and development of technology for tropical environments that encourages innovation, increases economic benefits, stimulates business growth, and improves the quality of human life while still trying to maintain a balance between technology itself and the environment shows the character and uniqueness of JTERAS.
