Author Guidelines

General Information

You are advised to read "About the journal", which includes other relevant information. All submitted manuscripts should contain original research not previously published and not under consideration for publication elsewhere. All authors have read and agreed to the manuscript content, and any experimental research reported in the manuscript has been performed with the approval of an appropriate ethics committee. Manuscripts may be rejected if the editorial office considers that the research has not been carried out within an ethical framework. Papers must be written in good English and manuscripts may be submitted for consideration as full articles, short reports, or reviews. Authors are urged to keep the length of regular papers to six printed pages or less. Short Reports can be no longer than four printed pages, including all spaces, references, figures, and tables. Manuscripts must be submitted by one of the authors of the manuscript, and should not be submitted by anyone on their behalf. The submitting author takes responsibility for the article during submission and peer review. The plagiarism must be under 25% to accept in this journal. Before that, you must check in Turnitin.

Article Publication Charge

JTLS charges authors from Indonesia an article publication fee of 3,000,000 IDR for each accepted article to cover the publication costs. Authors from countries other than Indonesia will be charged a fee of USD100 upon acceptance of their article for publication in this journal.

Preparing manuscript text

File formats

Format the manuscript similarly to a published paper, and file formats should be in  Microsoft Word or Rich Text Format (RTF). Users of other word processing packages should save or convert their files to RTF before uploading. The text should be single-spaced with 2.5 cm margins on the left and right sides in A4 size. Prepare figures at the publication-quality resolution, using only applications capable of generating high-resolution TIFF or JPG files. Please find the template in here.

Manuscripts for Research articles submitted to JTLS should be divided into the following sections:

Title page
The title should be concise and focused, providing a precise. clear. and succinct description of the research conducted, while avoiding the use of abbreviations. The authors' last names and initials should be provided, along with their department, institution, and city ( including postal code) and country. Additionally, please clearly indicate the corresponding author. Please provide a running title of not more than 60 characters and keywords from 3  and not more than 7.

The abstract of the manuscript should not exceed 350 words, abide strictly by this limitation of length. The abstract should comprehensively but succinctly describe the paper's contents to the reader, and abbreviations and reference citations should be avoided.


The background/introduction section should be written in a way that can be understood by researchers who may not have specialist knowledge in the field. It should provide a clear explanation, and if necessary, an illustration, of the research background and objectives. The section should conclude with a concise statement summarizing the key findings in the articles. This introduction should be typed in 400-800 words

This should be divided into subsections if several methods are described.

Results and Discussion
The Results and Discussion may be combined into a single section. They may also be broken into subsections with short, informative headings.

This should clearly state the main findings of the research and explain their importance and relevance. Summary illustrations may be included.

These should be included at the end of the text and not in the footnotes. Personal acknowledgments should precede those of institutions or agencies.

Abbreviations should follow SI symbols and those recommended by the IUPAC. Abbreviations should be defined in brackets after their first mention in the text. Standard units of measurement and chemical symbols of elements may be used without definition in the body of the paper.

The references should include only articles that are published or in the press. The references are each numbered and ordered sequentially as they appear in the text. Citations in the reference list should contain all named authors, regardless of how many there are.

Preparing illustrations and figures

Figures and images should be labeled sequentially, numbered, and cited in the text. Figures should be referred to specifically in the text of the paper but should be embedded within the text. The legends should be included from the main manuscript text file and being a part of the figure file (using Arabic numerals, the maximum figure title is 15 words, and the detailed legend is up to 300 words). The use of three-dimensional histograms is strongly discouraged when the addition of the third dimension gives no extra information. The following file formats can be accepted:
  - PDF (also especially suitable for diagrams)
  - PNG (preferred format for photos or images)
  - Microsoft Word (figures must be a single page)
  - PowerPoint (figures must be a single page)
  - TIFF
  - JPEG

Preparing tables

These should be numbered in sequence using Arabic numerals (i.e. Table 1, 2, 3 etc.). Tables should also have a title that summarizes the whole table, maximum 15 words. Table should be embedded into the text file but in portrait format (note that tables on a landscape page must be reformatted onto a portrait page or submitted as additional files).

Preparing additional files

Supplementary information is peer-reviewed material directly relevant to the conclusion of an article that cannot be included in the printed version owing to space or format constraints. Any additional files will be linked into the final published article in the form supplied by the author, but will not be displayed within the paper. They will be made available in exactly the same form as originally provided. 
If additional material is provided, please list the following information in a separate section of the manuscript text, at the end of the document text file:  separated the main manuscript file from the cover page, and please complete all metadata (description, author name, title, reference, and etc)

File name, please follow this format (First family name author_ The first 4 words of the title)
