Author Guideline
Aims and Scope
The Indonesian Journal of Tropical Agriculture (IJTA) is a scientific publication for articles reporting research findings policy analyses, and opinion related to agriculture in broad sense, i.e., agronomy, soil science, entomology, plant pathology, agricultural social-economics, nutrition food science and technology, biotechnology, agricultural engineering, biometry, biology, agroclimatology, animal Science, veterinary medicine, animal husbandry, fishery and forestry, and related agricultural area. The Publisher of the Journal invites agricultural scientists to send their manuscript in the above field of studies. All manuscripts are subject to critical review by peer group (reviewers) in the subject area and approval by the Editorial Board.
Submission of Manuscripts
Manuscripts to be published in IJTA include research papers, short communications, and reviews. The authors guarantee that the articles have not been published elsewhere. The papers should be written in English using appropriate format and corrected by an English language expert. The editor will not accept manuscripts that are deficient in these respects. The editor is not obligated to return the rejected articles.
On Line Submission. Authors have to submit on line by accessing the following website: http://jurnal.ipb.ac.id/index.php/ijta/about/submissions and simply click the “Make a new submission” button and then follow the instruction to submit on line. We only accept manuscript submission by on line submission, because it will reduce the overall editorial and reviewing process, and finally accelerate the publication.

Editorial Office: Institute for Research and Community Services (LPPM), Andi Hakim Nasoetion Building, 5th Floor, Jl. Raya Darmaga, IPB Darmaga Campus, Bogor, West Java, Indonesia 16680, Telp/fax: 0251-8622093/8622323, email: ijta-lppm@apps.ipb.ac.id
Manuscript submission must be accompanied by a covering letter from the corresponding author. The letter should clearly state the name of corresponding author, complete mailing address, phone and fax number, and e-mail address. Corresponding author is responsible for the originality of the research and the content of the manuscript. Other authors (if any) must approve of the submitted manuscript. To expedite the review process, authors must recommend at least two reviewers who are not members of their institution(s) and have never been associated with them or their laboratory (ies); please provide their contact information where indicated on the submission form.
Format
General. All parts of the papers, including abstract, titles of the tables and figures, table's footnotes, figure legends, and references should be double-spaced on quarto-size (letter) paper with 2 cm margin, using Times New Roman font with 12 font size. Figures and tables must be placed at the end of the manuscript, each of them on separate sheets. Figures and papers from previous publications can be used as long as there is consent from its authors. All pages, including the pages with figures and tables at the end of the paper, must be numbered consecutively. Research paper may occupy up to 4500 words, some figures and tables; or 15 pages maximum.
Reviews, written as continuous articles without the subheadings such as Materials and Methods, Results, and Discussion should not exceed 3500 words or 12 pages maximum including figures and tables.
Short article which contains research material for unique interest but not sufficient to form regular research article will be published as a short communication. The manuscript should be prepared in a single section without sub-headings such as Materials and Methods, Results, and Discussion; not exceed 3500 words.
For regular research papers, the presentation of the manuscripts should be as follows.
Title. The title page should include the title, the author's name(s), each author's institution and address, and a footnote containing the address to which all correspondence should be sent, complete with telephone and fax numbers as well as e-mail address. Please provide the title of the work in Indonesian also (for Indonesian author). For international author, editors of IJTA will translate the text.
Abstract. It must not exceed 250 words. Abstract contains a brief summary of the text, covering the whole manuscript without being too elaborate on every section. Avoid any abbreviation, unless it is a common knowledge or has been previously stated. Key words consisting of three to five words are listed in order of importance and placed below the abstract.
Introduction. This section must give sufficient background in order that readers can understand and evaluate the results without having to read previous publications related to the topic. Use only references that really support the discussion. Introduction includes the background and the objective of the research. Uncommon name of organism (local name) must be followed by its scientific name at the first use.
Materials and Methods. This section should contain sufficient technical information to enable the experiments to be reproduced successfully. If a special condition is needed, for example in centrifugation, it should specify the name of the machine, rotor model, temperature, time, and centrifugal speed (in x g). For widely recognized materials and methods such as media and determination of protein concentration, it is sufficient to mention the reference only. If there are commonly-used modified techniques, the authors must explain the technique briefly. For example, it is better to write “Cells are separated employing ultrasonic treatment as reported by Wiranto (1988)” instead of only “Cells are separated employing treatment reported by Wiranto (1988)”. Explain thoroughly if the method is new, likewise for uncommon equipment, materials, and microbial strain. If there are many strains or mutants used, present them in a table that contains the identities (name, code, collection number, source, and characteristics (physiological and genetic) of the strains, mutants, bacteriophages, plasmids.
The authors agree that any plasmids, viruses, and living materials such as microbial strains and cell lines described in the article are available for academic purposes. Any members of the scientific community can ask for those materials at reasonable cost for noncommercial purposes. Please also write the measurement unit in International Standard Units and type g L-1 rather than g/L.
Results. This section only contains research results, please state the data clearly and precisely in a past tense. Do not state references, or discuss the result either. Do not repeat the details of experiment in this section, which were already mentioned in the materials and methods section. Do not use too many tables and graphs if it can be explained briefly in the main text. Means in tables and graphs should be given standard deviation. Limit the use of photograph; present only the ones that clearly represent the results. Figures and tables must be numbered consecutively. Every figure and table showed must be cited on the text. Authors that used Microsoft Excell Program need to give the raw data. Add measurement scale on photos if needed, arrows should be given to point certain objects.
Discussion. This section contains the interpretation of the results and discussion that is related to previously reported results. Restating the methods, results, and other information presented in the introduction must be avoided.
Acknowledgment(s). This section can be used to acknowledge financial support received in funding the research and to appreciate the institutions or persons for their assistance in the research or in the writing process of the manuscript.
References. IJTA strongly recommends to use primary references only and use refencences managemant software such as Mendeley, Zotero ect. References are arranged in alphabetical order using Harvard referencing style. Please use the standard abbreviation of a journal's name according to the ISSN List of Title WordAbbreviations and refer to: [CSE] Council of Science Editors. 2006. Scientific style and format: the CSE manual for authors, editors, and publishers. 7th Ed. Reston (VA): The Council.
