Peer review declaration

All papers published in this volume of IOP Conference Series: Earth and Environmental Science have been peer reviewed through processes administered by the Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing. • Type of peer review : A group of reviewers with good reputation of international publication were assigned to review the manuscripts of ICOSAE 2020 using Konfrenzi Automated Conference System. Prior to the review process, all the reviewers were briefed by Prof. Ade Gafar Abdullah on a virtual meeting regarding the reviewing process. As many as 10 reviewers were then eligible in which each was sent 7 – 10 papers through the submission system. They were given two weeks to finish their review process and given a certain amount of incentive once they finish their task. After the deadline, the reviewed manuscripts were sent to the participants (authors) using the system through their personal account. The authors were given two weeks to revise their manuscripts and send them back to the committee using their account. Papers whose revision was in accordance with the reviewers’ comments went into final editing process (paper template layout checking, proofreading, etc.) and those which need further revision went into the second round of review process. All the manuscripts and other required data were submitted to IOP after they passed final editing. • Conference submission management system : Konfrenzi Automated Conference System • Number of submissions received : 99 • Number of submissions sent for review : 98 • Number of submissions accepted : 81 • Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100) : 81/99 x 100 = 81.8% • Average number of reviews per paper : 3 • Total number of reviewers involved : 10 • Any additional info on review process : • Name and affiliation of the contact Ade Gafar Abdullah PT Rumah Publikasi Indonesia Jl.
