Guide for author

1. Manuscript Preparation

Highlights. This journal requires highlights as they improve the visibility of your article in search engines. Highlights are a brief list of bullet points that summarize the unique findings and innovative methods used in your research study. Highlights should be submitted in a separate editable file in the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 90 characters, including spaces, per bullet point).

Graphical Abstract. Create a graphical abstract that visually summarizes the main results or findings of your research. You may use a concluding figure from your paper or create a new design specifically for this purpose. The purpose of the graphical abstract is to present key information in a quick and easily understandable format for readers. The graphical abstract will appear in press, proofs, and published papers. You can insert it within the text before the abstract, and no separate submission is required. Preferred file types: JPG, PNG, TIFF. Image size: please provide an image with a maximum of 4 * 8 cm (h * w). The image should be readable using a regular screen resolution of 300 dpi.

Research Data and supplementary materials. Note that publication of your manuscript implies that you must make all materials, data, and protocols associated with the publication available to readers. Disclose at the submission stage any restrictions on the availability of materials or information. Read the information about Supplementary Materials and Data Deposit for additional guidelines.

2. Essential title page information

Title. Ensure that the title of your manuscript is brief, precise, and pertinent. It should indicate whether the study involves human or animal trial data, systematic review, meta-analysis, or replication study. If you mention gene or protein names, use abbreviated names instead of full names. Avoid using running title or head as they will be removed by the Editorial Office.

Author list and affiliations. Make sure to provide the first and last names of all authors, and ensure that they are spelled correctly. If you prefer, you may include your name in your native language script following the English transliteration. Below the authors' names, list their affiliation addresses, indicating which author is associated with which address using a lowercase superscript letter. For each affiliation, provide the complete postal address and include the country name. If available, include the email address for each author.

Corresponding author. The person responsible for handling correspondence during the review and publication process, as well as after publication, should be clearly identified. This includes addressing any future inquiries about the methodology and materials used. The corresponding author must provide an up-to-date email address and contact information to ensure effective communication.

3. Research Manuscript Sections

Abstract & Keywords. The abstract should summarize the objectives conclusions in no more than 200 words. It has to be a clear, concise summary describing scope and purpose, methods or procedures, significant new results, and conclusions. The abstract should be written as one paragraph. At the end of the abstract, keywords should be given in 3 to 5 words or phrases.

Introduction. Outline the aims of the project and give sufficient context, refraining from an extensive review of the literature or a synopsis of the findings.

Material and methods. The article will undergo peer review and the final decision of its acceptance will be made by the editor before it is published in the journal XX. The Editorial Office of the journal will then produce the final paper layout in PDF format, which will be provided to the authors for proofreading. The uncorrected proof in PDF form will be published in the "Article in Press" section. Once the authors have corrected the proofreading, the final version of the article will be prepared and published in the "In Progress Issue" of the respective volume and issue number. Manuscript document submitted to this journal (in one MS Word or PDF file) should be arranged as follow: (a) Bodytext of manuscript article (from Title to References, without tables and figures); (b) Figure Captions and Table Captions; (c) Figures (one figure per page); and (d) Tables (one table per page). Please include a Covering Letter in a separated document file containing your summary of scientific finding and uploaded in Supplementary Files.

Results. Results should be clear and concise.

Discussion. The authors are advised to analyze and contextualize the results of their study with reference to previous research and the working hypotheses. The implications of the findings should be discussed in a wide-ranging context, and any limitations of the study should be emphasized. The section may also include a discussion of potential directions for future research. This section can be merged with the Results section if desired.

Conclusions. This section is not mandatory but can be added to the manuscript if the discussion is unusually long or complex.

Acknowledgments. Acknowledge the contributions of individuals who have assisted in the research, particularly those who have provided financial support. This may include advisors, financial sponsors, and other supporters such as proofreaders, typists, and suppliers who have provided materials. Do not acknowledge one of the author’s names.

Conflict-of-Interest Statement. In the manuscript, authors should disclose any conflicts of interest that may exist. This includes situations where an author, their institution, or employer have financial or personal relationships that could potentially influence or bias the manuscript. All authors must report potential conflicts of interest, including specific financial interests relevant to their manuscript, on the cover letter and the final page of the manuscript. Authors will be required to complete and submit a Form for Disclosure of Potential Conflicts of Interest. If no conflicts of interest exist, a disclosure statement should be included in the manuscript stating "The authors declare that they have no conflict of interest."

Funding. Disclose all funding sources for the study. Clearly indicate any grants received to support your research and whether funds were provided to cover publication costs. Providing detailed descriptions of the grant or award program is not required. If funding comes from a block grant or other resource available to a research institution, simply provide the name of the institute or organization that provided the funding. You can write with the format below: 

“This research was financed by [XXX]” or “This research was financially supported by [XXX], [write the affiliation country XXX] under grant number [XXX]”

If no funding has been provided for the research, it is recommended to include the following sentence:

“This research did not receive any specific grant from funding agencies in the public and commercial sectors.” 

References. Every time you take data or cite statements from other libraries, the writer is obliged to write the source of the reference. All that is referred to in the text must be registered in the Bibliography section, and vice versa, everything written in the Bibliography must be referred to in the text (Wang et al., 2011). All references referred to in the article text must be registered in the Bibliography section. Bibliography must contain references that come from primary sources (scientific journals and a minimum of 80% of the total bibliography) published in the last 10 (ten) years. Each article contains at least 10 (ten) references. Writing Bibliography should use reference management applications such as Mendeley, End Note, Zotero, or others. However, the author must keep checking independently of the bibliography that is generated because often the reference management application has format errors. The writing format used in the Jurnal Presipitasi is in accordance with the Elsevier Harvard 2 Citation Style format. Writing a bibliography using a reference management application needs to be checked one by one so that all quality sentences.

Reference style

All citations in the text should refer to:

1.  Single author: the author's name (without initials, unless there is ambiguity) and the year of

publication;

2. Two authors: both authors' names and the year of publication;
3. Ten or more authors: first author's name followed by 'et al.' and the year of publication.

Citations may be made directly (or parenthetically). Groups of references can be listed either first

alphabetically, then chronologically, or vice versa.

Examples: 'as demonstrated (Allan, 2000a, 2000b, 1999; Allan and Jones, 1999)…. Or, as demonstrated (Jones, 1999; Allan, 2000)… Kramer et al. (2010) have recently shown …'

List: References should be arranged first alphabetically and then further sorted chronologically if

necessary. More than one reference from the same author(s) in the same year must be identified by

the letters 'a', 'b', 'c', etc., placed after the year of publication.
