Format:  The paper size is set to A4. The manuscript is prepared with 1.25 inch left, 1-inch right, 2-inch top and 1-inch bottom margins. The header and footer of 1.0 inch and 0.6 inch are used, respectively. Unless specified, single column text with 10-point Times New Roman font on 12-point line spacing is used. Use ordinary upper- and lower-case letters throughout, except where italics are required. Start headings from the left margin. If you wish, you may indicate the ranking of complicated section headings and subheadings with numerals (1, 1.1, 1.1.1,...). All pages must be numbered in the top right-hand corner.

All figures and tables must be placed close to the first mention or explanation in the manuscript. Authors must not place figures and tables only in separate files or remove them from the manuscript.

Title:  Use 11-point bold font on 12-point line spacing.  The title is centered.  The length of title is not limited but it should not exceed 2 lines.  A title should be concise and informative.

Author Names:  Use 10-point font on 11-point line spacing.  Author names are centered with one line space below the title. Begin with the first name of the author followed by the last name.  For more than one author, separate each name by a comma (,), and identify each author’s affiliation by superscript numbers at the end of the author’s last name. 

Author Affiliations:  Use 9-point font on 10-point line spacing.  Author affiliations are centered with one line space below the author names.  Include institutional and e-mail addresses for all authors.  Place superscript numbers at the beginning of each affiliation accordingly.

Abstract:  Use 10-point font on 11-point line spacing for heading and 9-point font on 11-point line spacing for abstract content. The Abstract must not exceed 300 words .  The purpose and setting of the research, the principal findings and major conclusions, and the paper's contribution should be briefly stated.  Please note that excessive statistical details should be avoided, and abbreviations/acronyms should be used only if it is essential or firmly established.

Keywords:  List up to 7 keywords and separate each keyword by a comma (,).  The keywords should accurately reflect the content of the article.  The keywords will be used for indexing and searching purposes.

Main Text: Use 10-point font on 12-point line spacing.  The main body of the submitted manuscript should contain the sections in the following order: introduction, methodology, results (if any), discussion (if any), conclusion, acknowledgements, and references.  Please note that some articles may not contain all the components above.  Tables or figures must be included in the text for the reviewing process. 

Tables: Use 9-point font on 10-point line spacing for all text in tables. The table caption is above the table. The table should always be cited in text in numbered consecutively. Footnotes to tables should be typed below the tables and should be referred to by superscript numbers. Tables should not duplicate results presented elsewhere in the manuscript (e.g., in graphs).  

Figures: ****(IMPORTANT)****

Authors must prepare all figures as high-resolution image files, at least 300 dpi in png or jpg, suitable for journal publication. Figures must not be created directly in MS Word using shapes, text boxes, arrows, or grouped objects, because these elements may shift during two-column formatting and may reduce the quality of the final published article.

All figures should be prepared using professional graphic or scientific software, such as Adobe photoshop, Canva, MATLAB, R, Python, or other appropriate applications. Flow charts, conceptual diagrams, graphical abstracts, and process diagrams must be exported as a single high-quality image file. 
For graphs, all elements must be clear and readable at the final publication size. Axis titles, axis values, legends, data labels, symbols, error bars, and statistical indicators must not be too small, blurred, crowded, or distorted.

Authors must not capture or screenshot figures from MS Word, PowerPoint, PDF, or screen displays, as this usually produces low-resolution images that are unsuitable for publication. Text, arrows, labels, symbols, and annotations must be embedded in the original figure file, not added later in MS Word using text boxes or floating objects.

For figures containing subfigures, such as Figure 1(a), Figure 1(b), and Figure 1(c), all subfigures must be combined into one complete figure within the original graphic application before submission. Subfigure labels, including (a), (b), (c), etc., must be placed inside the figure file itself. Authors must ensure that all text, axis labels, legends, symbols, and annotations remain clear and readable after resizing to the journal’s two-column format.

All Figures must be cited in text in consecutive numerical order.

Recommended figure requirements: 

  • Minimum resolution: 300 dpi at final publication size.
  • Preferred format for diagrams and flow charts: PNG.
  • All subfigures must be arranged as one complete figure file.
  • Do not draw figures directly in MS Word.
  • Do not add labels or text using MS Word text boxes.
  • Do not submit screenshots or low-resolution captured images.
  • Ensure that all text and labels are sharp and readable.

Format of References:  JCST uses the American Psychological Association (APA version 7) referencing style, which can be found at

Short details: Intext-citation pattern is (author’s last name, year).
A work by only authors, i.e., (Sukjaidee, 2020). 
A work by two authors, i.e., (Yuangnun, & Krukimsom, 2020). 
A work by three or more authors, i.e., (Yuangnun et al., 2023). 

When the author’s name is used as part of the sentence, use a narrative citation as follows:

For a work by one author:  Sukjaidee (2020) reported that ...
For a work by two authors: Yuangnun and Krukimsom (2020) found that ...
For a work by three or more authors: Yuangnun et al. (2023) demonstrated that ...

1) Authors must ensure that every in-text citation appears in the reference list and that every reference listed is cited in the manuscript.
2) References should be listed at the end of article, arranged alphabetically according to the last names of the authors and then chronologically.  A digital object identifier (DOI) should be added at the end of each reference if its DOI exists.
3) Citation of a reference as “in press” implies that the item has been accepted for publication.  Authors are responsible for the accuracy of the content of the references.

GRAPHICAL ABSTARCT 

Start from Volume 15 (2025): The accepted article will be requested for graphical abstract:

1. Size Dimensions

  • Typical Aspect Ratio: Landscape orientation with aspect ratio of 16:9. and 300 DPI (dot per inch)

  •  it’s generally suggested to use a size of approximately 1200 × 630 pixels for better visibility on web platforms.

 2. What is a Graphical Abstract?

A Graphical Abstract is a concise visual representation of the main findings or the essence of a research article. It is designed to provide a quick overview of the study’s purpose, methods, key results, and implications, often serving as a complement to the textual abstract. Graphical abstracts are increasingly common in scientific publications, especially in fields like chemistry, biology, medicine, and engineering.
