The 4th International Conference on Biosciences (The 4th ICoBio) https://biologi.ipb.ac.id/web/en/page/icobio/ Introduction of the 4th ICoBio 2021 The International Conference on Biosciences (ICoBio) is a biennial international conference organized by the Department of Biology, Faculty of Mathematics and Natural Sciences, IPB University, Indonesia, since 2015. For this year, the 4th ICoBio 2021 was held in conjunction with the 17th National Congress of the Indonesian Biological Society (PBI), and it also collaborated with Universiti Putra Malaysia (UPM), Malaysia. The conference was held on 10-12th August 2021. This conference was designed to facilitate academicians, researchers, students, and practitioners related to the field of biosciences worldwide to gather and share information, ideas, knowledge, and research results as well as to strengthen research network and collaboration in a fruitful scientific environment. This year’s conference was held virtually due to COVID-19 pandemic and lockdown in several areas around the world that limited the travelling permit issue.It is beyond doubt that biosciences play a central role in every aspect of life. Bioscience and innovations are closely related with various inter and trans-disciplinary fields, leading to practical solutions which may contribute to Sustainable Development Goals (SDGs) strategic issues occurring in the disruptive era of industrial revolutions 4.0. Indeed, today we are facing serious issues including food and feed security, energy scarcity, healthcare issues, global warming, and others. Integration of biological fields with engineering, information technology, economy, and social sciences may serve as potential strategies to combat such challenging issues. Therefore, this kind of innovation and finding urgently needs to be informed to the science society this year.The 4th ICoBio 2021 was taking the theme “Bioscience Innovations for Sustainable Development Goals”. This conference was intended to gain insight into current trends in research and development related to biology, such as interdisciplinary approaches that are important for understanding biology and its applications. Research topics in this conference were divided into five main groups focusing on (1) Biodiversity, Conservation Biology and Climate Change; (2) Bioprospecting, Health Issues, and Industrial Biology; (3) Omics, Bioinformatics, and Computational Biology; (4) Techno-biology and Bioengineering; and (5) Smart and Sustainable Agro-maritime.The 4th ICoBio 2021 also served as a place for realizing existing collaboration between the Department of Biology, IPB University with its national and international partners, such as Universiti Putra Malaysia, Malaysia, and Kasetsart University, Thailand, Tottori University, Japan, and also strengthening collaboration with University of Missouri, Colombia, USA; and Iowa State University, USA. We also expect to build partnerships with China Agricultural University, China; Sher-e-Kashmir University of Agricultural Sciences & Technology, Chatha Jammu, India; Mariano Marcos State University, Philippines; and CNRS - Museum National d’Histoire Naturelle, Universite de Paris, France in the near future.The 4th ICoBio 2021 invited two prominekeynotes and six well known invited speakers related to the theme. The conference was attended by prominent speakers and participants from several countries, including Malaysia, Thailand, Philippines, India, China, Japan, the USA, France and Indonesia. In total, there were 217 registered participants consisting of 181 oral presenters and 36 participants only. The oral presenter has a 10 minutes presentation and a five minutes discussion with peers in the parallel classroom.LIST OF COMMITTEE ICOBIO 2021 are available in this pdf.
