Author Guidelines

  1. Policy and Submission of Manuscript

The Indonesian Journal of Engineering and Science (IJES), is a peer-reviewed journal covering all areas of science and technology, launched in 2020. It is published 3 Issues in a year by the Asosiasi Peneliti Sriwijaya.

Manuscripts should be written in English and be submitted either online at Submission.

Once received, all papers will be subject to peer review by experts in the field. Every manuscript is assessed in a double-blinded review in which the author’s identity is not revealed to the reviewers. We encourage authors to submit the names of five referees suitable to review the work to aid in the peer review process. We aim to review all papers within 4-8 weeks and if accepted the paper will appear in the next available issue of the journal.

  1. Manuscript Preparation

Authors are encouraged to download the IJES template at TEMPLATE when preparing their manuscript. In the case of traditional submissions, the manuscript should be double-spaced and in Times New Roman, 10 pt with a 3-cm margin around a standard A4 page.

Manuscripts should be arranged as follows:

  • Title page. The title page should include:
  1. A concise and informative title.
  2. Authors’ names.
  3. Names and addresses of the institution of the author.
  4. running title (an abbreviated form of the title) not longer than 40 letters and spaces.
  5. E-mail address of the corresponding author.
  • Abstract. The abstract must be no more than 250 words and should be concise and include only the most important aspects of the study. Four to six keywords should be given below the abstract.
  • Text. The text should be subdivided into IntroductionMaterials and MethodsResults and Discussion, and Conclusions. General points for authors to consider include:
  1. Please ensure that your manuscript has been spell-checked and grammar-checked before submission to remove trivial errors.
  2. Papers should be written in either American or British English but must be consistent throughout the paper-do not use both in the same paper.
  3. Abbreviations and acronyms should be used sparingly and consistently. When they first appear in the text, the complete term should be given, e.g. DMF = dimethylformamide.
  4. Use only symbol and normal text character sets when inserting Greek letters (a), German umlauts (ä), accents (é) etc.
  5. All scientific units must be preceded by a space, for example: ‘... for 2.5 h at 50 °C’ not ‘... for 2.5h at 50°C’.
  6. Use tab stops for indents not the space bar.
  7. Use the table function and not spreadsheets to create tables.
  8. Use the equation editor or an equivalent for equations. For authors using Word 2007 or later use the Microsoft equation editor rather than the default editor.
  • AcknowledgementsAcknowledgements of people, grants, funds etc should be included in a section just before the references. The names of funding agencies, scholarships etc should be written in full.
  • References. References in the text should be cited in the manuscript by Arabic numerals in square brackets and numbered sequentially in order of citation. They should, if applicable, be before punctuation (example: text [1,2].). If multiple citations are used they should appear as follows: [1-3]. Proper abbreviations for all journals must be used. For a complete listing of the standard abbreviations of a journal’s name please see:

Note that for books or journals in the Thai language the title of the book or journal and names of authors should be given in English while the year should be reported in the Christian calendar (2011 not 2554 BE). After the title of the book or journal the words in Thai should follow in parenthesis. [8] J Angkathavanich. Garcinia fruit and weight loss (in Thai). J. Food Pharm. 1998; 52, 16-9.

  • TablesTables should be typed on separate pages and numbered using Arabic numerals with a caption written in normal text. For example: ‘Table 3 Characterization data for complexes 1-3.’ The table must also be cited in the text. Footnotes to the table should be included where necessary as superscript lower case letters with the text in Times New Roman, 9 pt (example: aAt 298 K). References to previous work presented in the table should also be included in the footnotes.
  • Figures, schemes and illustrationsGraphics such as figures, schemes and illustrations should be placed on separate pages or in the text and numbered using Arabic numerals. As with tables the figure captions must be written in normal text and must be cited in the text. Other points to consider include:
  1. Figure captions should be written Fig. 1. Text.
  2. The graphics must be submitted as *.jpg or *.tif files.
  3. They must have a minimum resolution of 600 dpi for good reproduction.
  4. Images from other authors’ work must be properly referenced.
  5. Figures containing text must have the text embedded in the figure file.
  6. Use simple fonts such as Arial for text in the figure.
  7. Do not use faint lines and check that all fonts are legible at final size.
  8. Try to avoid color graphs, charts and lines as these are often not distinguishable when printed in black and white.
