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: Single-blind Table 1 shows the evaluation aspects in the review process at The 3rd ICoGEE 2021. Several essential things in scientific articles are reviewed through this evaluation aspect, such as novelty, originality, clarity of methods and analysis, and their significance in science and technology. If an evaluation aspect has less than good quality, the reviewer provides suggestions for improvement, and the author must improve it or provide feedback. The reviewer will also offer recommendations such as: (i) accept without revision (if all aspects of the evaluation have exceptional score), (ii) accept with minor revision (if there are less than two evaluation aspects whose quality is below good), (iii) accept with major revision (if there are about 2 - 4 evaluation aspects that are below good quality), and (iv) reject (if more than four evaluation aspects have below good quality or are considered not to meet the essential requirements of scientific articles). • Conference submission management system: For official The 3rd ICoGEE 2021 webpage, we used: http://icogee.org, while for paper management system, we used Easy Chair: https://easychair.org/conferences/?conf=icogee2021 • Number of submissions received: 197 • Number of submissions sent for review: 197 • Number of submissions accepted: 114 • Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100): 57,86% • Average number of reviews per paper: 2 • Total number of reviewers involved: 41 • Any additional info on review process: All papers had undergone plagiarism check (using Turnitin) and single-blind review by two reviewers • Contact person for queries: Name : Yuant Tiandho Affiliation : Department of Physics, Universitas Bangka Belitung Email : [email protected] / [email protected]
