Introduction :

The official language of the journal is either Bahasa Indonesia or English
Types of paper :

• Research Articles: Original and unpublished work e.g. controlled trials, intervention studied, studies of screening and diagnostic test, cost effectiveness analyses, case-control series, and surveys or monitoring program. Generally, manuscripts should not exceed 8,000 words, the maximum word length being 10,000 can be accepted after consultation with Editor-in-Chief. The length of a paper should be commensurate with the scientific information being reported. In particular, the introductory material should be limited to a few paragraphs and results presented in figures should not be repeated in tables.

• Short Communication: A brief communication of urgent matter or the reporting of preliminary findings to be given expedited publication. Maximum 4000 worlds excluding references and abstract and up to 10 references.

• Reviews: Critical assessments of literature and data sources. Those wishing to prepare a review should first consult the Editors or Associate Editors concerning acceptability of topic and length.

Article structure

Title.
Concise and informative. Avoid abbreviations  and formulae where possible. No more than 20 words.

Author names and affiliations.
Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author. Please indicate the corresponding author who will handle correspondence at all stages of refereeing and publication, also post-publication. 

Abstract
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, methodology, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself. No more than 250 words.

Keywords
Immediately after the abstract, provide a maximum of 5 keywords, general and plural terms should be avoided.

Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Material and methods
Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.

Results and Discussion
Results should be clear and concise. Discussion should explore the significance of the research work while extensive citations and discussion of published literature should be avoided. A separate Results and Discussion is often appropriate.

Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Acknowledgements
Acknowledgements contains a list of individuals who provided help during the research (e.g., sampling taken, providing language help, writing assistance or proof reading the article, etc.).

References

Citation in text
Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text

Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

Reference style
References should be arranged first chronologically and then further sorted alphabetically if necessary.

Examples in the manuscript body :
'”…The application of marine bioremediation in Indonesian water is relatively new (Weber et al., 1994a; Weber et al., 1994b; Heipieper et al., 1995). Biomass estimations were calculated according to
Smith et al. (1986). White et al., (2014) have recently shown ....'”

Example in reference list : 

References should be arranged first alphabetically and then further sorted chronologically.  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.

Additional notes:
Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.(then 1.1., 1.2., ...), 2, etc. (the abstract is not included in section numbering).

Figure captions
Ensure that each illustration has a caption. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Tables
Number tables consecutively with Arabic numerals in accordance with their appearance in the text. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article. Tables should never be included within the text, because file(s) containing tables are attached separately in the electronic submission system.
