  2. Author(s) full name
  3. Author(s) full address
  4. Correspondence author: E-mail
  6. Keywords
  12. ACKNOWLEDGEMENT (optional)

Author's Information. Author's full name (no abbreviations) including a full valid street address for each institution and an email address. When a manuscript is written by several authors from different institutions, then superscript numerals are used to refer the authors, and also the corresponding author should be identified.

ABSTRACT. Abstract to be a concise (max. 250 words) and complete report of the work that can stand alone without further explanation. It should include: the objectives/hypothesis of the study and justification for conducting the investigation, the material and methods used, the main results obtained and significant conclusions that can be drawn. The abstract should not include an extended discussion of your results, references, tabulated data and any abbreviations unless they are widely understood (e.g., DNA, pH, USA).

Keywords consisting of 3 to 5 words should be listed in order of importance. These may be composites (e.g. 'coastal management, 'population dynamics'), but they should not be phrases or sentences. Keywords are the most pertinent informative words pertaining to the research.

INTRODUCTION. Composed of the background of the research and mentioning previous studies that had been done. State question(s) or hypotheses that are needed to be answered through your work.

MATERIALS AND METHODS. Methodology creates the context for evaluating the data, presenting how samples and measurements, are collected, what controls are used, what variables are and are not considered, which assumptions are made; all these things play an important role in the interpretation of the results. If a well-known method was applied, there should be a reference to the paper in which it is described. When a well-known method is modified, there should be a clear mention of which part was modified.

RESULTS. State the obtained results based on the given methods. The same data may not be presented in both table and graph format. References are not normally given in the RESULTS section. Whenever possible, all data should be displayed as tables or graph.

DISCUSSION. Discuss the results/data by comparing the currently reported data with the previous results. Highlight the similarities, as well as the differences, and the uniqueness of the current finding. Explain why the result(s) are significant. End the discussion with a conclusion and an indication of possible future research. End the discussion by giving a conclusion and an indication of possible future research in that particular topic.

CONCLUSION. The conclusion of a research paper needs to summarize the content and purpose of the paper. It should briefly restate the topic as well as explaining why it is important; rephrase the thesis statement; and briefly, summarize the main points. If and when needed, the author can state to the readers that there is a need for further research on the paper's topic.

ACKNOWLEDGEMENT. Authors may thank people who have helped the work and acknowledge funding sources.

REFERENCES. Marine Research in Indonesia (MRI) has a reference template in popular reference management software products, such as Mendeley and EndNote. If you use a reference management software, please ensure that you remove all field codes before submitting the electronic manuscript.

Users of Mendeley Desktop can easily install the reference style for MRI by downloading styles via the following link:  You may open Mendeley Desktop, then choose view > citation style > more style.

If you are not referencing management software users, please follow the format of the sample references and citations as shown in this Guide. References should be in the APA-like style (please refer to the example of the exception). They should be listed at the end of the paper and arranged in alphabetical order (first author's surname).

Papers from books, conference reports, symposium proceedings, etc.: Give the title of the cited article, the editor(s) and title of the volume, the publisher and place of the publisher (not the location where the conference was held), and the pages of the article. The date of the citation must be the year of publication (not the year in which the conference was held).

Dissertations: Write the title in lower case, 'MS/Ph.D. thesis/dissertation' (no spaces or periods in 'MS' or 'Ph.D.'), and give the university and its location.
