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: For validating scientific and technical research of paper submitted to IOP, we already did single-blind review, that is reviewers know the identity of authors, but authors do not know the identity of reviewers. By keeping reviewers anonymous allows us to critique work without being influenced by authors. Authors cannot contact the reviewer since they do not know who they are.The review process carried out on the papers submitted to the Sustainable Island Development Initiatives - International Conference 2019 (SIDI-IC 2019) has been organized in a common manner as conducted by most conference organizers, as follows:1. Each paper has been peer reviewed by two reviewers.2. A paper is accepted for publication if the two corresponding reviewers give the confirmation of the acceptance.3. For the case where one reviewer gives the confirmation of accepted the paper, but the other reviewer does not give the confirmation of accepted the paper, then a third reviewer is assigned to review. The final decision is in accordance with the confirmation of the third reviewer whether the paper was accepted or rejected.4. The committee of the SIDI-IC 2019 has then documented the papers which were accepted and rejected for publications at IOP EES.5. The papers accepted for publication were then sent back to the corresponding authors for revisions in accordance with the comments and requirements of the corresponding peer reviewers.6. The papers that have been revised by the authors were then sent back to the committee to be processed for final editing by the assigned SIDI-IC 2019 paper editors.7. Finally, all the papers that have been completely checked and edited were compiled and submitted to IOP EES.• Conference submission management system: 1st SIDI International Conference 2019 used Microsoft Conference Management Toolkit (https://cmt3.research.microsoft.com/) as conference submission management system• Number of submissions received: 93.• Number of submissions sent for review: 93.• Number of submissions accepted: 71.• Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100): Acceptance rate = 71/93 x 100% = 76.3%• Average number of reviews per paper: Average number of reviews per paper are 2.• Total number of reviewers involved: Total number of reviewers involved are 24.• Any additional info on review process: -• Contact person for queries: Prof. Eko B Djatmiko – Institut Teknologi Sepuluh Nopember, Indonesia

Peer Review Declaration

All papers published in this volume of IOP Conference Series: Materials Science and Engineering 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 The peer reviewing process is a vital step to ensure the quality of published papers in the 4th ICES. The conference required all received scientific papers to go through the double-blind reviewing process (i.e., each paper was evaluated by 2 reviewers independently of each other). If any paper got discrepant review results from two reviewers, the paper must be sent to a third reviewer for evaluation. In reviewing process, authors and reviewers’ identities are hidden to each other. More than 200 experts and academic researchers in various engineering fields collaborated to review and evaluate the conference papers to make sure that all received papers meet necessary criteria for publication and acceptance.• Guidelines for Reviewers (Criteria for accepting and declining papers) 1. The Responsibility of the Peer Reviewer The peer reviewer is responsible for critically reading and evaluating a manuscript in their specialty field, and then providing respectful, constructive, and honest feedback to authors about their submission. It is appropriate for the Peer Reviewer to discuss the strengths and weaknesses of the article, ways to improve the strength and quality of the work, and evaluate the relevance and originality of the manuscript.2. Before Reviewing Please consider the following:• Does the article you are being asked to review match your expertise? • Do you have time to review the paper? • Are there any potential conflicts of interests? 3. The Review When reviewing the article, please keep the following in mind:Content Quality and Originality, Organization and Clarity, Title, , Introduction, Method, Results/Discussion, Conclusion, Tables, Figures, Images, Scope, Final Comments, Next Steps, Conference Management System, Conference Number of Submissions, Plagiarism Check System are available in the pdf• Contact person for queries Alaa M.

Research on Crisis Management of Conference and Exhibition Enterprises in Post-Epidemic Era

The crisis is ubiquitous, the situation of the world today is extremely complicated, and the epidemic that ravages the world brings more uncertain factors to the global economic development and social stability. The convention and exhibition industry has been hit hard, and many planned convention and exhibition activities have been canceled. Under this background, the stakeholders, social managers and scholars of the exhibition industry pay new attention to how to cope with the impact of the crisis, which has become the focus of attention. Based on this, through combing the literature, discussing the types of the convention and exhibition crisis and the present situation of the convention and exhibition enterprises, this paper discusses the problems in the crisis management of the convention and exhibition enterprises, and puts forward the corresponding strategies to promote the benign development of the convention and exhibition enterprises and provide a new research direction for the research of the topic.
