General Notes

Article Types

JKK accepts articles in the form of research articles, case studies, and literature reviews. However in one issue we limited the number of literature review articles.


JKK accepts articles in Indonesian and English. Please, make sure that the Indonesian language used is good and correct. Meanwhile, for articles in English, make sure the spelling and grammar are good and correct.


Manuscript Organization

The manuscript should be follow the JKK template.  Original research and case study manuscripts must contain the essential elements needed to convey the content in clearly defined sections: Title, Abstract, Introduction, Materials and Methods, Results, Discussion and/or Conclusions, Figures and Tables with Captions, and any Supplementary Material required. If the manuscript is a literature review, it must contain: Title, Abstract, Introduction, Material Problems, Discussion and/or Conclusions. The text should be in single-column format and the layout of the text should be as simple as possible.



Please provide a title that is concise and informative; ideally it should contain no more than 12 words. Titles are often used in information-retrieval systems so please keep in mind that your choice of title may impact how easily readers can discover your article.

Authors and Institutions

The author's name is completed with the name and address of the institution and correspondence email.


Please define all abbreviations at first use.


The abstract should state briefly the purpose of the research, the principal results and major conclusions. Abstracts are often presented and read as stand-alone text, so please keep this in mind when writing, and avoid the use of references and abbreviations.


Please provide adequate background information, while avoiding a detailed literature review, and state the objectives of your work in light of previous findings. Convey state of the art research on your topic and point out the novelty of your manuscript. Convey your theory in a concise manner, then end with your research / writing objective and hypothesis (if any).

Materials and Methods

Please provide sufficient detail to allow the work to be reproduced. Previously published methods should be shown in a reference; you only need to describe relevant modifications.


Results should be clear and concise.


A Discussion should explore the significance of the results of the work, not just repeat them. A combined Results and Discussion section is often appropriate.




The main conclusion(s) of the study may be presented in a short Conclusions section, as a stand-alone section or in form of a subsection of the Discussion or Results and Discussion section. Make sure that the conclusions do not contain repetitive results, because the conclusions should have implications for the findings or discussion on the manuscript.


Please collate all acknowledgements in a separate section at the end of the article, before the references.


The JKK reference and citation format refers to the Vancouver format (Vancouver style). All references mentioned in the References list are cited in the text, and vice versa. Use sub-title References for reference that are cited in the text; and use sub-title Bibliography if reference as source reading and aren’t cited in the text.

Figure Captions

Please provide figure captions at the end of your manuscript. A caption should be self-contained and consist of a brief title and a concise description of the illustration. All symbols and abbreviations used should be explained.


We recommend providing tables within your manuscript file where possible, ideally using a single table grid for each individual table, otherwise using tabs to separate columns. Please submit tables as editable text and not as images. You should number tables consecutively in accordance with their appearance in the text and place any table notes below the table body.

Editorial Procedures

Our editorial procedures take you step-by-step through the various paths a paper can take once it has been submitted.


Submission to JKK is online only using our editorial system. You will be guided through the process step by step, and you will be able to track the progress of your manuscript through the system. Submission guidelines to JKK can follow the submit tutorial on the journal page.


Errata and Corrigenda

We will publish a correction of your article if a significant error is discovered after publication. An Erratum will be published if we introduced the error; a Corrigendum if the author introduced the error.


Articles may be withdrawn, retracted, removed or replaced after publication if they contain substantial errors that cannot be corrected by publishing an Erratum or a Corrigendum, or if ethical violations come to light after publication.
