Publication Ethics and Publication Malpractice Statement

The Journal of Statistical Applications and Computational Statistics (Jurnal Aplikasi Statistik dan Komputasi Statistik/JASKS) is a non-profit international scientific association of distinguished scholars engaged in engineering and science devoted to promoting researches and technologies in engineering and science field through digital technology. JASKS are peer-reviewed international journals. This statement clarifies ethical behavior of all parties involved in the act of publishing an article in The Journal of Statistical Applications and Computational Statistics (Jurnal Aplikasi Statistik dan Komputasi Statistik/JASKS), including the authors, the editors, the peer-reviewers and the publisher.

Ethical Guideline for Journal Publication

The publication of an article in a peer-reviewed The Journal of Statistical Applications and Computational Statistics (Jurnal Aplikasi Statistik dan Komputasi Statistik/JASKS) 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 authors, the journal editors, the peer reviewers, the publisher and the society.

Pusat Penelitian dan Pengabdian kepada Masyarakat (PPPM) Politeknik Statistika STIS as publisher of this Journal 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, PPPM STIS and Editorial Board of JASKS will assist in communications with other journals and/or publishers where this is useful and necessary.

Publication decisions

The editors of the JASKS are 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.

Non-Discrimination

The editors and reviewers evaluate manuscripts for intellectual content without regard to race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy of the authors.

Confidentiality

Fair play

An editor at any time evaluate manuscripts for their intellectual content without regard to race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy of the authors.

Confidentiality

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.

Promptness

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.

Confidentiality

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.

Acknowledgement 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

Reporting standards

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 behaviour and are unacceptable.

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 behaviour and is unacceptable.

Acknowledgement 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, 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 other 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.

Withdrawal of Manuscripts

Authora are not allowed to withdraw submitted manuscripts, because the withdrawals are waste of valuable resources that editors and referees spent a great deal of time processing submitted manuscript, money and works invested by the publisher.

Checklist for preparing your paper for submission

1. Is your manuscript written in Journal of Statistical Applications and Computational Statistics (format)? At this stage, it is essential that you follow every detail of the Journal of Statistical Applications and Computational Statistics format. Please try to follow the format as closely as possible.

2. is your title adequate and is your abstract correctly written? The title of the paper should be informative and completely self-explanatory (no citation in the abstract), provide a clear statement of the problem, the proposed approach or solution, and point out major findings and conclusions.

3. Authors are suggested to present their articles in the structure of the section: Introduction - The Proposed Method/Algorithm/Procedure specifically designed (optional) - Research Method - Results and Discussion – Conclusion. Authors may present complex proofs of theorems or non-obvious proofs of correctness of algorithms after introduction section (obvious theorems & straightforward proofs of existing theorems are NOT needed).

4. Introduction section: explain the context of the study and state the precise objective. An Introduction should contain the following three parts:

• Background: Authors have to make clear what the context is. Ideally, authors should give an idea of the state-of-the-art of field the report is about.
• The Problem: If there was no problem, there would be no reason for writing a manuscript, and definitely no reason for reading it. So, please tell readers why they should proceed with reading. Experience shows that for this part a few lines are often sufficient.
• The Proposed Solution: Now and only now! - authors may outline the contribution of the manuscript. Here authors have to make sure readers point out what are the novel aspects of authors' work. Authors should place the paper in proper context by citing relevant papers. At least, 15 references (recently journal articles) are cited in this section to support your state of the art.

5. Method section: the presentation of the experimental methods should be clear and complete in every detail facilitating reproducibility by other scientists.

6. Results and discussion section: The presentation of results should be simple and straightforward in style. This section reports the most important findings, including results of statistical analyses as appropriate and comparisons to other research results. Results given in figures should not be repeated in tables. This is where the author(s) should explain in words what he/she/they discovered in the research. It should be clearly laid out and in a logical sequence. This section should be supported suitable references.

7. Conclusion section: Summarize sentences the primary outcomes of the study in a paragraph. Are the claims in this section supported by the results, do they seem reasonable? Have the authors indicated how the results relate to expectations and to earlier research? Does the article support or contradict previous theories? Does the conclusion explain how the research has moved the body of scientific knowledge forward?

8. Language. If an article is poorly written due to grammatical errors, while it may make it more difficult to understand the science.

9. Please be sure that the manuscript is up to date. It is expected that 40 to 80% of references are recent papers.

10. Is the manuscript clearly written? Is the article exciting? Does the content flow well from one section to another? Please try to keep your manuscript on the proper level. It should be easy to understand by well qualified professionals, but at the same time please avoid describing well known facts (use proper references instead). Often manuscripts receive negative reviews because reviewers are not able to understand the manuscript and this is authors' (not reviewers') fault. Notice, that if reviewers have difficulties, then other readers will face the same problem and there is no reason to publish the manuscript.

11. Do you have enough references? We will usually expect a minimum of 25 to 30 references primarily to journal papers, depending on the length of the paper. Citations of textbooks should be used very rarely and citations to web pages should be avoided. All cited papers should be referenced within the text of the manuscript.

12. Figures and Tables.
Relation of Tables or Figures and Text:
Because tables and figures supplement the text, all tables and figures should be referenced in the text. Avoid placing figures and tables before their first mention in the text. Authors also must explain what the reader should look for when using the table or figure. Focus only on the important point the reader should draw from them, and leave the details for the reader to examine on her own.

Figures:
a. All figures appearing in the article must be numbered in the order that they appear in the text.
b. Each figure must have a caption fully explaining the content.
c. Figure captions are presented as a paragraph starting with the figure number i.e. Figure 1, Figure 2, etc.
d. Figure captions appear below the figure.
e. Each figure must be fully cited if taken from another article
f. all figures must be referred to in the body of the article

Tables:
a. Material that is tabular in nature must appear in a numbered captioned table.
b. All tables appearing in the article must be numbered in the order that they appear in the text.
c. Each table must have a caption fully explaining the content with the table number i.e. Table 1, Table 2, etc.
d. Each column must have a clear and concise heading
e. Tables are to be presented with a single horizontal line under the table caption, the column headings, and at the end of the table.
f. All tables must be referred to in the body of the article
g. Each table must be fully cited if taken from another article

13. Each citation should be written in the order of appearance in the text in square brackets. For example, the first citation [1], the second citation [2], and the third and fourth citations [3], [4]. When citing multiple sources at once, the preferred method is to list each number separately, in its own brackets, using a comma or dash between numbers, as such: [1], [3], [5], or [4]-[8]. It is not necessary to mention an author's name, pages used, or date of publication in the in-text citation. Instead, refer to the source with a number in a square bracket, e.g. [9], that will then correspond to the full citation in your reference list. Examples of in-text citations:

• This theory was first put forward in 1970 [9].
• Zadeh [10] has argued that...
• Several recent studies [7], [9], [11]-[15] have suggested that...
• ... end of the line for my research [16].

14. Self-citations: to control for citation manipulation (COPE, 2019), this journal asks that authors keep self-citation to a minimum. We would strongly recommend no more than 5 (including jointly authored publications), or 20% self-citations, whichever number is lower. 

15. Please be aware that for the final submission of a regular paper you will be asked to tailor your paper so the last page is not half empty.

A high quality paper should has:
(1) a clear statement of the problem the paper is addressing;
(2) the proposed solution(s); and
(3) results achieved. It describes clearly what has been done before on the
problem, and what is NEW.

(3) About Figures & Tables in your manuscript:
- Because tables and figures supplement the text, all tables and figures should be REFERRED in the text. Authors MUST EXPLAIN what the reader should look for when using the table or figure. Focus only on the important points the reader should draw from them, and leave the details for the reader to examine on her own.
- Tables are to be presented with a single horizontal line under: the table caption, the column headings and at the end of the table. All tables are produced by creating tables in MS Word. Captured tables are NOT allowed.
- All figures MUST be presented in high quality images

(4) Please ensure the maximum page of your final paper is 8-pages for normal publication fee, but still allow up to 16 pages (required to pay an extra fee after 8 pages, USD50 per page).

Policy of Plagiarism Detection

Retraction and Correction policies

JASKS takes its responsibility to maintain the integrity and completeness of the scholarly record of our content for all end users very seriously. Changes to articles after they have been published online may only be made under the circumstances outlined below. JASKS places great importance on the authority of articles after they have been published and our policy is based on best practice in the academic publishing community. An Erratum is a statement by the authors of the original paper that briefly describes any correction(s) resulting from errors or omissions. Any effects on the conclusions of the paper should be noted. The corrected article is not removed from the online journal, but notice of erratum is given. The Erratum is made freely available to all readers and is linked to the corrected article. A Retraction is a notice that the paper should not be regarded as part of the scientific literature. Retractions are issued if there is clear evidence that the findings are unreliable, this can be as a result of misconduct or honest error; if the findings have previously been published elsewhere without proper referencing, permission, or justification; if the work is plagiarized; or if the work reports unethical research. To protect the integrity of the record, the retracted article is not removed from the online journal, but notice of retraction is given, is made freely available to all readers, and is linked to the retracted article. Retractions can be published by the authors when they have discovered substantial scientific errors; in other cases, the Editors or Publisher may conclude that retraction is appropriate. In all cases, the retraction indicates the reason for the action and who is responsible for the decision. If a retraction is made without the unanimous agreement of the authors, that is also noted. In rare and extreme cases involving legal infringement, the Publisher may redact or remove an article. Bibliographic information about the article will be retained to ensure the integrity of the scientific record. A Publisher’s Note notifies readers that an article has been corrected subsequent to publication. It is issued by the Publisher and is used in cases where typographical or production errors (which are the fault of the Publisher) affect the integrity of the article metadata (such as title, author list, or byline) or will significantly impact the readers' ability to comprehend the article. The original article is removed and replaced with a corrected version. Publisher’s Notes are freely available to all readers. Minor errors that do not affect the integrity of the metadata or a reader's ability to understand an article and that do not involve a scientific error or omission will be corrected at the discretion of the Publisher. In such a case, the original article is removed and replaced with a corrected version. The date the correction is made is noted on the corrected article. Authors should also be aware that an original article can only be removed and replaced with a corrected version less than one year after the original publication date. Corrections to an article that has a publication date that is older than one year will only be documented by a Publisher’s Note. The following guideline may also be helpful: COPE Guidelines for Retracting Articles
