Publication Ethics Statement
Extrapolasi is a peer-reviewed national journal. This statement clarifies ethical behavior of all parties involved in the act of publishing an article in this journal, including the author, the chief editor, the Editorial Board, the peer-reviewer and the publisher (Program Studi Sarjana Teknik Sipil Fakultas Teknik Universitas 17 Agustus 1945 Surabaya). This statement is based on COPE’s Best Practice Guidelines for Journal Editors.
Ethical Guideline for Journal Publication
The publication of an article in a peer-reviewed Extrapolasi is an essential building block in the development of a coherent and respected network of knowledge. It is a direct reflection of the quality of the work of the authors and the institutions that support them. Peer-reviewed articles support and embody the scientific method. It is therefore important to agree upon standards of expected ethical behavior for all parties involved in the act of publishing: the author, the journal editor, the peer reviewer, the publisher, and the society.
Program Studi Sarjana Teknik Sipil Fakultas Teknik Universitas 17 Agustus 1945 Surabaya as the publisher of Extrapolasi takes its duties of guardianship over all stages of publishing extremely seriously and we recognize our ethical and other responsibilities. We are committed to ensuring that advertising, reprint or other commercial revenue has no impact or influence on editorial decisions. In addition, the Program Studi Sarjana Teknik Sipil Fakultas Teknik Universitas 17 Agustus 1945 Surabaya and Editorial Board will assist in communications with other journals and/or publishers where this is useful and necessary.
The editor of the Extrapolasi is responsible for deciding which of the articles submitted to the journal should be published. The validation of the work in question and its importance to researchers and readers must always drive such decisions. The editors may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism. The editors may confer with other editors or reviewers in making this decision.
An editor at any time evaluates manuscripts for their intellectual content without regard to race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy of the authors.
The editor and any editorial staff must not disclose any information about a submitted manuscript to anyone other than the corresponding author, reviewers, potential reviewers, other editorial advisers, and the publisher, as appropriate.
Disclosure and conflicts of interest
Unpublished materials disclosed in a submitted manuscript must not be used in an editor's own research without the express written consent of the author.
Duties of Reviewers
Contribution to Editorial Decisions
Peer review assists the editor in making editorial decisions and through the editorial communications with the author may also assist the author in improving the paper.
Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process.
Any manuscripts received for review must be treated as confidential documents. They must not be shown to or discussed with others except as authorized by the editor.
Standards of Objectivity
Reviews should be conducted objectively. Personal criticism of the author is inappropriate. Referees should express their views clearly with supporting arguments.
Acknowledgment of Sources
Reviewers should identify relevant published work that has not been cited by the authors. Any statement that an observation, derivation, or argument had been previously reported should be accompanied by the relevant citation. A reviewer should also call to the editor's attention any substantial similarity or overlap between the manuscript under consideration and any other published paper of which they have personal knowledge.
Disclosure and Conflict of Interest
Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
Duties of Authors
Authors of reports of original research should present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the paper. A paper should contain sufficient detail and references to permit others to replicate the work. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable.
Data Access and Retention
Authors are asked to provide the raw data in connection with a paper for editorial review, and should be prepared to provide public access to such data (consistent with the ALPSP-STM Statement on Data and Databases), if practicable, and should in any event be prepared to retain such data for a reasonable time after publication.
Originality and Plagiarism
The authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others that this has been appropriately cited or quoted.
Multiple, Redundant or Concurrent Publication
An author should not, in general, publish manuscripts describing essentially the same research in more than one journal or primary publication. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable.
Acknowledgment of Sources
Proper acknowledgment of the work of others must always be given. Authors should cite publications that have been influential in determining the nature of the reported work.
Authorship of the Paper
Authorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the reported study. All those who have made significant contributions should be listed as co-authors. Where there are others who have participated in certain substantive aspects of the research project, they should be acknowledged or listed as contributors. The corresponding author should ensure that all appropriate co-authors and no inappropriate co-authors are included on the paper and that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication.
Hazards and Human or Animal Subjects
If the work involves chemicals, humans, animals, procedures or equipment that have any unusual hazards inherent in their use, the author must clearly identify these in the manuscript.
Disclosure and Conflicts of Interest
All authors should disclose in their manuscript any financial or another substantive conflict of interest that might be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be disclosed.
Fundamental errors in published works
When an author discovers a significant error or inaccuracy in his/her own published work, it is the author’s obligation to promptly notify the journal editor or publisher and cooperate with the editor to retract or correct the paper.

Sources of Support
Extrapolasi's daily operational is mainly supported by the Civil Engineering Department, Universitas 17 Agustus 1945 Surabaya. Our office and equipment are provided by the department at level 1 of the department's building.
Extrapolasi also constantly supported by Universitas 17 Agustus 1945 Surabaya's management, especially Direktorat Sistem Informasi Universitas 17 Agustus 1945 Surabaya in maintaining our IT needs being an online journal.
Civil Engineering is one of engineering science branch that studies how to design, build, renovate not only buildings and infrastructure, but also includes the environment for the benefit of human life. Meanwhile, Civil Engineering Study Program at 17 August 1945 University of Surabaya is a study program that has 5 scientific fields. They are the field of structure, geotechnics, transportation, water affairs and management. To support these five scientific fields, there are other disciplines that have an important role. For example, mathematics, physics, statistics and probability.
Extrapolation is a scientific form of mathematics which is the process of estimating the value of a variable beyond its original observation interval based on the relationship with other variables. Extrapolation plays an important role in 5 scientific fields in the Civil Engineering Study Program. One of them is in the water affairs field, extrapolation estimates supporting data in estimating lost rain data. In the transportation field, extrapolation is used to calculate LHR data, population growth data, and trip attraction generation data. In the structural field, it is used to estimate compressive strength data and concrete research. Whereas in the geotechnical field, extrapolation is used to predict soil data which can be used in foundation planning later.
Based on the important role mentioned above, extrapolation is the reason for choosing the name of a journal in the Civil Engineering Study Program, where extrapolation itself can enter into all scientific fields in Civil Engineering.
