Author Guidelines

The manuscript management process is done online through the JKKI webpage. The submitted manuscript will first encounter the editorial screening to ensure the manuscript meets the review eligibility, the compliance of author guidelines, plagiarism check (Turnitin) <20. If the manuscript does not meet the initial requirements, the manuscript will be declined (stated as reject) and not be processed for review. If the author decides to resubmit, the author must make improvements and resubmit the improved manuscript as a new submission. 

The selection of manuscripts published in JKKI uses a double blind peer-review system. All manuscripts received will be discussed by a minimum of 2 experts in the relevant fields of science and editorial executive. The review process is carried out within a maximum of 2 months for the first round of review.

The reviewed manuscript can be categorized into 4:

1. Accepted without repairing (Accepted Submission), 
2. The manuscript requires author revision before acceptance (Required Revision), 
3. The author must make fundamental improvements and the manuscript will go through a review process again (Resubmit for Review), 
4. The manuscript cannot be accepted for publication (Decline Submission). 

A duration of 2 weeks is given to improve since the result is announced. The authors, who do not improve the manuscript within 2 weeks, are automatically considered to cancel the publication and also canceling all previous acceptance statements.

Manuscript withdrawal in the review process can be done without returning the review cost while the reviewed manuscript will be charged for withdrawal fee. Manuscript that has been accepted cannot be withdrawn.

Accepted manuscripts will go through a process of editing by the editors. The author then must approve the results of editing, through copying editing stages by the instructions given. Approval time is not more than two weeks. After the editing approval process, the manuscript undergoes a layout process before publication. The author also must approve laying out the results of pre-printing and publication within one week. Manuscript publication is made online before hardcopy editions.

Submission

The submitted manuscript should be addressed to the editor-in-chief of JKKI. Manuscripts must be submitted through online submission by registered users. All manuscripts should be accompanied by a cover letter from the author responsible for correspondence. To do submission Click here

Article types

1. ORIGINAL/RESEARCH ARTICLE

Original contributions are manuscripts containing substantial novel research. These articles can include randomized controlled trials, observational (cohort, case-control, or cross-sectional) studies, diagnostic accuracy studies, nonrandomized behavioral and public health intervention trials, experimental animal trials, or any other clinical or experimental studies.

Manuscript Preparation

The manuscript should be written in English. The manuscript should be formatted as follows: typed using Microsoft Word, printed on A4 paper size, single-spacing in a Cambria font, 12-point (except in the special section, discussed below); the upper, lower, left, and right margin is 2.5 cm and limited to approximately 16 pages in length including references, tables, and figures. The main body text consists of 3500-5000 words (excluding title, abstract, acknowledgment, references, tables and figures). Number pages consecutively in the bottom center of each page, beginning with the title page. Each manuscript component should begin on a new page in the following sequence:

The abstract should be concise and clear so it allows readers to understand the important news aspects without having to read the entire article. Below the abstract, provide a list of 3–10 keywords, that can assist for indexing purposes.

c. Introduction

This section should be written without subtitles, and contain background information such as prior work and the objective of the study. Describe the rationale of the study (need and significance). Summarise the previous relevant research and explain the author’s finding (pro and contra results). Describe the novelty of the study and the objective of the study.

d. Methods

• This section may be divided by subheadings
• Should be described in detail, including research design, population, study subjects, selection of subjects or study sample, sample size determination, data sources, data collection techniques/instruments, intervention, measurements, laboratory analysis, statistical analysis, ethical clearance as well as research place and period. Methods should be clear so the reader can replicate them. If the author used a new method, it must be written along with the references. The use of measuring instruments that require specific permission from certain institutions requires a document containing the license information or registration numbers.
• For qualitative study, the methods should include three domains of qualitative studies: (1) Research team and reflexivity, including personal characteristics and relationships with participants (2) Study design, including theoretical frame and participant selection, setting, and data collection (3) analysis and findings including data analysis and reporting.
• Units of Measurement: Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or liter) or their decimal multiples. Temperatures should be in degrees Celsius. Blood pressure should be in millimeters of mercury unless other units are specifically required by the journal.
• Statistical Methods: any software used in data analysis must be stated clearly. In manuscripts that report on randomized clinical trials, authors may provide a flow diagram in CONSORT format and all of the information required by the CONSORT checklist. The CONSORT statement, checklist, and flow diagram are available on the Consort website. For tables comparing treatment groups in a randomized trial (usually the first table in the trial report), significant differences between or among groups (i.e. p<0.005) should be identified. In general, p values should be reported to three decimal places (i.e. p<0.001).
• Ethics: Authors are required to describe in their manuscripts ethical approval from an appropriate committee (include also the number of ethical approvals) and how consent was obtained from participants when research involves human participants and animals. For articles concerning experimental research on humans, a statement should be included that shows informed consent of subjects was obtained following a detailed explanation of the procedures that they may undergo. 

e. Result

• This section may be divided by subheadings. It should provide a concise and precise description of the experimental results and their interpretation. Tables or figures should be numbered in the text sequentially, written in single-space, font Cambria size 10. Tables and figure insertion must be done efficiently without duplication. One result only needs to be presented in one presentation from either figure or table, but not both. The table title should be precise, clear, and located above the table. The title of the pictures should be short and clear and located below the image. Both titles should be placed aligned left and suitable for the image and table. Important points in the figure must be annotated and described in the caption or figure legend, which should be written in font Cambria size 10
• The maximum number of tables and pictures is six (6) in one (1) manuscript. Do not use internal horizontal or vertical lines, the border is only used in the column headings and the end of the table. Give each column a short or abbreviated heading. Authors should place explanatory matter in footnotes, not in the heading. Any symbols must be placed properly and described in the caption. Figures should be either professionally drawn and photographed or submitted as photographic quality digital prints. 
• For x-ray films, scans, and other diagnostic images, as well as pictures of pathology specimens or photomicrographs, send sharp, glossy, black-and-white, or color photographic prints. The ID of the patient should not be displayed.  
• Tables consecutively in the order of their first citation in the text and supply a brief title for each.
