Abstract

Green technology as an integration of modern technology and environmental science is applied to conserve the sustainable fulfilment of human needs by preserving environment and natural resources. In the application of green technology, the development and utilisation of products, equipment, and systems are carried out by minimising the negative impacts of human activities to the surrounding. Among the main purposes of green technology application is to ensure the sustainability of human and the ecosystem. The sustainability is related to the current living compliance by considering the supply availability of future generations. In the future, green technology is considered to be the means of achieving the human living goals. People have started avoiding the employment of technology that raising negative impacts to the environment. An application model of alternative conventional technology to comply with green technology concept is waste recycle process. This process significantly minimise the side effect to the environment by reducing the pollutant generated by human activities.The 9th Engineering International Conference (EIC) was conducted on September 24th, 2020. Following the WHO’s advice for the public due to the Covid-19 pandemic and the Indonesian government regulation to avoid crowded or indoor settings, Faculty of Engineering Universitas Negeri Semarang (UNNES), as a conference organizer which is located in Sekaran Gunungpati Semarang- Indonesia, decided to set up this year annual conference virtually. In consequence of the uncertainty surrounding and resolving the current traveling difficulties, the 9th EIC was conducted on Zoom and broadcasted on YouTube as well.The conference was started with a plenary session by four keynote speakers from Hong Kong, Malaysia, New Zealand, and Indonesia. Each of them delivered the speech in 45 minutes and had Q&A session for 15 minutes. This session was guided by qualified and experienced moderator from Faculty of Engineering UNNES. The four keynote speakers were delivering the speech from their place by joining the Zoom meeting.After plenary session, the 97 presenters from Indonesia, Malaysia, Brunei Darussalam, and Taiwan were divided into five meeting rooms in Zoom based on the manuscript’s topics to have a parallel session presentation. Each room had a moderator who managed the presentation and Q&A session. The presenters asked to record and send a 10 minutes video presentation to be shown in the parallel session. Each presenter should be online in the room when the video played which followed by the Q&A session. The parallel session discussion run well and interactive, so it can improve participants’ understanding based on the material presented. It also aims to synchronize perception toward certain material.In general, the virtual conference was successfully conducted with the hard work from the committee, keynote speakers’ cooperation, and the presenters’ participation. All of the participants joined the conference from opening to closing without any significant problems. At the end of the agenda, the committee announced the best video presentation from each parallel room to appreciate a great effort in preparing the presentation. Finally, all of the keynote speakers, presenters, and participants got a certificate of participation as a proof of conference contribution.This proceeding covers manuscripts in the engineering areas. Research results, new ideas, information, and application related to the theory, design, development, implementation, testing or evaluation in the areas of green technology are presented. The concepts of green technologies, facilitate the goals of keeping the environment intact and improving it for civilization to survive.List of Advisory Board, Technical Committee, Scientific Committee are available in this pdf.
