Author Guidelines

Language in the manuscripts

JPT publishes articles in English, but manuscripts may initially be submitted in English or Indonesian. Authors submitting in Indonesian must provide an English version before final publication. For manuscripts demonstrating a high degree of scientific novelty, the editorial team may offer assistance with translation into English. Eligible authors will be notified by email. Authors remain responsible for the accuracy and scientific meaning of the final English text.

Format

Manuscripts must be submitted as editable Microsoft Word files (.doc or .docx) and prepared using the JPT manuscript template. PDF files or other formats are not accepted as the main manuscript file. Editable files are required for processing in production.

Type and Length

JPT accepts the following manuscript types. Page limits apply to manuscripts prepared using the JPT manuscript template and include abstracts, references, tables, and figures. 

1. Original Research Articles
Complete reports of original research contributing new knowledge to plant protection science or practice. Manuscripts should normally be 10–15 pages. The main text should include Introduction, Methods, Results, Discussion, and Conclusions. Results and Discussion should be presented separately.

2. Review Articles
Critical reviews of published research that evaluate current knowledge, identify research gaps, and suggest future directions relevant to plant protection. Manuscripts should normally be 10–20 pages. The main text should include Introduction, Methods, Results and Conclusions. The Methods section must explain how the literature was searched, selected, and synthesized. The Results section presents the findings of the literature synthesis, while the Discussion evaluates their significance, limitations, and implications. Authors should explain the scope of the review and how the literature was selected. Systematic reviews and meta-analyses must describe their search strategies, selection criteria, and analytical methods.

3. Short Communications
Concise reports of focused original research or significant findings relevant to plant protection. Manuscripts should normally be 5–9 pages, with no more than four tables and figures combined. The main text should include Introduction, Methods, Results and Discussion, and Conclusions. Results and Discussion should be presented separately. Short Communications undergo the same peer-review process and must meet the same scientific and ethical standards as Original Research Articles.

Additional Provisions
All manuscript types must include the required declarations. Supporting appendices of up to four additional pages may be included when necessary. Larger datasets or additional supporting materials should be submitted as separate supplementary files. Manuscripts outside these page ranges may be considered at the editor’s discretion when scientifically justified.

Title

A title of 20 (twenty) words maximum should be provided.

Author details and authorship

All contributing authors’ names should be added, including their correct email. The names are arranged in the correct order for publication. An email address signed and provided for the corresponding author. The full name of each author must be present in the exact format they should appear for publication. The affiliation of each author must be written entirely.

The criteria of authorship as follows; Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; drafting the work or revising it critically for important intellectual content; final approval of the version to be published; Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriate, investigated and resolved.

Authors should include their names, affiliations, and corresponding author’s contact information in the submitted manuscript. Authors are not required to submit a separate title page or an anonymized manuscript. Before sending the manuscript for external peer review, the JPT editorial team will prepare an anonymized version by removing author-identifying information from the manuscript and its file metadata.

Abstract

Authors must supply a structured abstract in their submission, including purpose, design/methods/approach, findings/results, and conclusion. A maximum of 250 words in total, excluding keywords. It has to be available in English and Indonesian languages. Please avoid the use of abbreviations and do not cite references in the abstract.

Keywords

Authors should provide up to five keywords or short phrases that represent the main topics of the manuscript. Keywords should be arranged alphabetically and separated by commas.

Manuscript organization

The body of the manuscript should be organized (at least) into the IMRaD structure as follows;

Introduction

It provides adequate background or context (problem and its significance) of the study. The subject should not be written extensively. It is expected that the rationale or purpose of the study (gap analysis), the objective in general and specific, and hypothesis (if any) should be expressed clearly. Present a clear "state of the art" of the subject, which discussed literature and theoretical concepts behind it. A concise general background may be included in the article.

Methods

It provides sufficient details to allow the work to be reproduced by an independent researcher. Methods must be shown clearly and in detail. If quoting directly from a previously published method, use quotation marks, and also cite the source. Any modifications to existing methods should also be described. Indicate the participants observed, including demographic data, number of respondents, the rationale of respondents selection, etc. Describe the experiment's design, such as the experiment procedures, surveys, interviews, observation characteristics, etc. Write the complete research procedure. Be sure that the article's explanations will allow other researchers to reproduce the work or do future work out of it.

Results

The author must write results in a logical sequence. Results with important findings should be present first. Results and discussion are written separately and presented sequentially, from the main to supporting data. Each showed result must be mentioned in the methodology. When presenting results in a table or figure, do not repeat all those contents in the text. Present only the summary of the text. Describe only new and important aspects of the study. Do not repeat all information from the results section or any section above—present limitation of the study. Write the issues that are new or unsolved for future research. This section consists of the information on what/how the presented data were produced, and no raw data should be present in the article. The produced data are presented in tables or figures with an explanation of what is the result/findings from work. The title of the image is written below the picture.

Discussion

The author needs to address connections between findings and basic concepts or hypotheses made earlier. Authors should also express whether any arguments were needed relating to other works from other researchers. Write implications made by the work related to theoretical or applications.

Conclusions

The conclusions should directly address the study objectives and summarize the main findings and their contribution to plant protection science or practice. All statements must be supported by the results. Do not introduce new data, repeat the abstract, or provide further discussion. Where appropriate, include practical implications or recommendations supported by the findings. Write this section as a concise paragraph without bullet points.

Acknowledgment

Acknowledge individuals or organizations that contributed to the work but do not meet all authorship criteria, and briefly describe their assistance. Authors must obtain permission from all individuals named in this section before submission. Financial support must be reported separately in the Funding Statement.

Declaration

Author contribution

Clearly state the roles of each author in conducting the research and writing the manuscript. Identify the corresponding author and describe specific contributions, for example: [Author Name] is the main contributor and corresponding author. [Other Author Names] are co-authors who contributed to [specific contributions]. All authors have read and approved the final manuscript.

Funding statement

Indicate whether the research received funding from any institution. If there is no specific funding provided, state: This research did not receive funding from public, commercial, or not-for-profit organizations. If author has specific funding, state: This research was funded by [Name of Funding Institution], grant number [Grant Number, if applicable], on behalf of [PIC name]

Competing interest

Authors must disclose any financial or nonfinancial interests that could reasonably be perceived to influence the research or its reporting. If no competing interests exist, state:
“The authors declare that they have no competing interests.”

If competing interests exist, identify the author(s) concerned and describe the relevant relationships or interests, including employment, consultancy, patents, commercial interests, or other relevant associations. Disclosure does not automatically disqualify a manuscript from consideration.

AI Use Declaration

Beginning with the December 2026 issue, all articles must include an AI Use Declaration, regardless of their submission date. Authors must accurately state whether and how AI-assisted tools were used, in accordance with JPT’s AI Usage Policy.

Figures and tables

All Figures (charts, diagrams, line drawings, web pages/screenshots, and photographic images) should be submitted directly in the manuscript's main body. All Figures should be of high quality, legible, and numbered consecutively with Arabic numerals. Graphics may be supplied in color to facilitate their appearance on the online database.

Tables should be typed and included in the main body of the article. The tables' position should be inserted in the text as close to the point of reference as possible. Ensure that any superscripts or asterisks are shown next to the relevant items and have corresponding explanations displayed as footnotes to the table, figure, or plate.

References

The reference style follows the APA citation format, with modifications to align with the journal's overall style.

Each literature that refers to and finds in the article (author, year) must be written in the references. Inciting an article written by two authors, the two family names must be mentioned, for example, Habazar and Yanti (2017) or (Habazar and Yanti, 2017). If an article written by three or more authors, only the first author's family name is mentioned, followed by et al. Writing et al. plus comma if followed directly by the year of publication. If the year is in parentheses, then et al. not followed by a comma. Writing words et al. not in italic style, for example, Lina et al. (2012) or (Lina et al., 2012).

Quotations that are indicated by the word "cit" or originating from an uncertain source (anonymous) must be avoided. The references for data that have not been published yet and personal communication are not displayed in the references. Still, they must be written directly in the text, for example: (Rifai, 2017; personal communication) or (Setyawan, 2017; unpublished data).

The reference is written alphabetically without numbering. In the references list, the first author's family name is placed in the front, while the next author's name is written with the abbreviated first name. The article's title is not in italic style and written in small letters unless there are certain writing conventions, such as place names. Journal names must be written in full, not in italic style, and must not be abbreviated. The references should be carefully checked for completeness, accuracy, and consistency.

All references are recommended to write down in reference tool manager i.e. Mendeley and arranged in alphabetical order should be supplied as follows:
