5. Citation and Reference Writing Rules

5.1. EJMI Hybrid IEEE–APA 7th Edition Reference Style

Journal Marine Inside (EJMI) adopts a hybrid IEEE–APA 7th Edition referencing style, combining:

  1. IEEE-style numerical citations: Sources are cited using numbers in square brackets, assigned consecutively in the order in which the sources first appear in the manuscript.
  2. APA 7th Edition bibliographic formatting: The details of each reference entry follow APA 7th Edition conventions for author names, dates, source titles, journal information, publishers, and DOI/URL presentation.
  3. Numerically ordered reference list: The reference list is numbered and arranged in citation order, not alphabetically. This ordering and numbering are EJMI-specific modifications to standard APA 7th Edition.

Authors must apply all three components consistently. Neither the default IEEE style nor the default APA 7th Edition style may be used without modification, because neither exactly reproduces EJMI's hybrid format.

5.2. In-Text Citation Rules (IEEE Numerical System)

  • First citation: Number each source consecutively, starting from [1], according to its first appearance in the manuscript.
  • Repeated citation: Use the same reference number whenever the source is cited again; do not assign a new number.
  • Narrative citation: When author names form part of the sentence, place the citation number immediately after the name. Examples: Rajan and Kumar [1] reported ...; Prasad et al. [2] investigated ....
  • Parenthetical-style numerical citation: When author names are not stated, insert the citation number at the relevant point in the sentence. Example: Previous maritime engineering studies have examined this relationship [3].
  • Author-name convention: Use the author's surname for a single-author source; both surnames for a two-author source; and the first author's surname followed by et al. for three or more authors when names are mentioned in the text. The square-bracketed citation number is always required.
  • Multiple sources: Cite each relevant source by number, preferably in ascending numerical order, for example [1], [3], [5]. Do not substitute an APA author–date citation such as (Rajan & Kumar, 2009).
  • Figures and tables: Cite the original source when material is adapted, reproduced, or derived from a prior publication, including where applicable permission or license details.
  • Citation–reference correspondence: Every source cited in the manuscript must appear in the reference list, and every numbered reference must be cited in the manuscript.

5.3. Reference List Rules (APA 7th Edition Bibliographic Formatting)

  • Place the reference list under the heading References.
  • Number references consecutively as [1], [2], [3], and so on, following the order of first citation in the text.
  • Do not arrange the reference list alphabetically. A reference that first appears as [3] in the manuscript must occupy entry [3] in the reference list.
  • Format each entry following applicable APA 7th Edition conventions: surname and initials, year in parentheses, sentence case for article and book titles, appropriate italicization of source titles and volume numbers, issue numbers in parentheses, page ranges or article numbers, and publisher information.
  • Include the DOI, when available, as a resolvable URL in the form https://doi.org/xxxxx. For web content without a DOI, include a reliable source URL when required by APA 7th Edition.
  • For books, do not include the publisher's city or country, consistent with APA 7th Edition.
  • For ordinary static web pages, do not add an access date unless the content is designed to change over time and an applicable retrieval date is needed.
  • Use a 10 mm hanging indent for continuation lines of each bibliographic entry, keeping the bracketed reference number clearly aligned with the entry. Use no extra blank lines between references, consistent with the EJMI manuscript template.
  • Verify all names, dates, titles, journal information, page ranges, publishers, DOIs, and URLs. Authors must not include nonexistent, irrelevant, or uncited sources.

5.4. Reference Formats by Source Type

The following are format templates, not actual publications. Replace all bracketed placeholders with accurate bibliographic data. The examples of numbering illustrate first-citation order only.

A. Journal article

Format: [n] Author, A. A., & Author, B. B. (Year). Article title in sentence case. Journal Title, Volume(Issue), page–page. https://doi.org/xxxxx

Example template: [1] Surname, A. A., & Surname, B. B. (2024). Article title describing a maritime engineering study. Journal Title, 12(2), 101–115. https://doi.org/xxxxx

B. Book

Format: [n] Author, A. A. (Year). Book title in sentence case (Edition, if applicable). Publisher.

Example template: [2] Surname, C. C. (2023). Book title about marine engineering (2nd ed.). Publisher Name.

C. Thesis or dissertation

Format for repository item: [n] Author, A. A. (Year). Title of thesis or dissertation [Doctoral dissertation or Master's thesis, Institution Name]. Repository Name. URL

Example template: [3] Surname, D. D. (2022). Thesis title about maritime safety [Master's thesis, University Name]. Institutional Repository. URL

For an unpublished thesis or dissertation, use the applicable [Unpublished doctoral dissertation] or [Unpublished master's thesis] descriptor and name the institution, without inventing a repository URL.

D. Conference paper or proceedings contribution

Format: [n] Author, A. A. (Year). Paper title in sentence case. In E. E. Editor (Ed.), Proceedings title (pp. xx–xx). Publisher. https://doi.org/xxxxx

Example template: [4] Surname, E. E. (2023). Conference paper title. In F. F. Editor (Ed.), Proceedings of the Conference Name (pp. 10–20). Publisher Name. https://doi.org/xxxxx

For a published conference paper formatted as a journal article, use the journal-article format instead.

E. Website or online page

Format: [n] Author or Organization. (Year, Month Day). Title of webpage. Website Name. URL

Example template: [5] Organization Name. (2024, March 15). Title of a maritime guidance webpage. Website Name. https://example.org/page

If the author and website name are the same, omit the repeated website name. Use (n.d.) if no date is available. Include a retrieval date only where appropriate under APA 7th Edition.

F. Indonesian laws and regulations

Because Indonesian legislation has distinctive official naming conventions, EJMI uses an APA 7th Edition–informed legal reference format while preserving the complete legal identity of the instrument.

Format: [n] Issuing authority. (Year). Type and number of regulation concerning its official subject. Official gazette or official government source (where applicable). URL

Example template: [6] Government of the Republic of Indonesia. (Year). Government Regulation Number XX of Year YYYY concerning [official subject]. Official Government Source. URL

Do not invent regulation numbers, promulgation dates, gazette details, or legal titles. Verify them against the official legal database before citation.

G. Research dataset or technical report

Dataset format: [n] Author, A. A. (Year). Dataset title (Version, if any) [Data set]. Repository. https://doi.org/xxxxx

Technical report format: [n] Organization or Author. (Year). Report title (Report No. XX, if any). Publisher or Organization. URL

5.5. Using Mendeley or Other Reference Managers

Authors are encouraged to manage references with Mendeley, Zotero, EndNote, or comparable software. However, selecting the standard APA 7th Edition output style will ordinarily produce author–date citations and alphabetically ordered references, which does not meet EJMI's hybrid requirements.

Authors must instead use an approved customized citation style (for example, an appropriate customized CSL style), or verify and adjust the final manuscript so that:

  1. In-text citations appear as [1], [2], [3], etc., in order of first appearance.
  2. Repeated citations retain the same assigned number.
  3. The reference list is numbered in the same citation order.
  4. Individual reference entries follow APA 7th Edition bibliographic conventions.
  5. Citation numbering is rechecked after any insertion, deletion, or rearrangement of citations.
  6. All available DOI links are checked for accuracy and functionality.

Failure to comply with the EJMI hybrid IEEE–APA 7th Edition reference style may result in a request for technical revision before peer review or publication.

6. Image and Table Presentation

  • Images should be centered with the figure number and title placed below the image in Times New Roman, 12 pt bold. The spacing between the image and the caption is one line, and the spacing between the caption and the text below is also one line.
  • Tables should be centered with three horizontal lines and vertical lines as needed. The table title should be placed above the table, aligned to the left, and written in Times New Roman, 12 pt bold. There should be no spacing between the title and the table, but one line spacing between the table and the text below it.

7. Manuscript Submission

  • Manuscripts must be submitted online through the journal's website: https://ejournal.poltekpel-banten.ac.id/index.php/ejmi/.
  • Authors must register to obtain a username and password before submitting a manuscript.
  • Authors are allowed to submit a maximum of two articles per issue, with only one article as the main author.
