Author Guidelines
The editor receive submission of research articles and literature reviews in the fields of chemistry and natural science, for their publication in the Journal of Chimica et Natura Acta. Other types of the articles such those ideas or concepts are excluded for publication in the journal. The length of manuscript should be about 10 pages of A-4 papers at maximum, including tables, graphs, and figures. The rules for writing of the articles are as follow:
Review articles
For publishing in the journal, this type should be a critical and comprehensive analysis of actual topics, which are based on innovative new findings and recently published in literature sources. The writing of an articles starts with its Title and the Name(s) and address of Author(s), followed by an abstract (in English, provided with keywords), and “Abstrak” (in Indonesian Language), provided with “kata kunci”), Introduction, Discussion, and Conclusions, and finished with Acknowledgement and References.
Research Articles
Articles of this type should be reports on results of researches conducted by workers. Evaluation criteria applied to this type of articles are primarily their originality [i.e. they are not duplicates of anyone else’s work and that materials of the article have not been previously published either by the author(s) or the researcher(s)], their reliability of the contents, clarity of description, contribution to the advancement of science and usefulness for academic community, and their scientific quality in general. The writing of each of articles should follow the following format:
Title
The title of an article should be made in both Indonesian language and in English, each of which should be brief, descriptive, and informative, with a maximum of 25 words. The title should be written in capital letters (excepting Roman names which should be written in italic and only their first letters are written in capital letters), and must neither contain any abbreviation nor chemical symbol. The full name of author should be written, but only under the first title version of article, and without any of their titles of scientific degree. Following the name of author(s), the institution and its postal address of each of the authors should also be written in order to facilitate communication.

The abstract, which in the essence of the content of an article, should include a background, objective(s), methods, results, and conclusions of the research conducted. Each version of the abstracts should be provided with keywords, which are written immediately below the abstract.
Introduction
In essence, “Introduction” contains a justification to the importance of the research conducted, supported by relevant references.
Materials and Methods
This section describers materials used in the research conducted, including detailed specifications and the origin of the materials, to give information to those who interested in use of and repeating the same method(s) and enabling them to get similar and reproducible results. If the method used in the research conducted had been previously described by other researcher(s) in the literature, then relevant source(s) should be cited and referred.
Results and DiscussionResults and Discussion section present results of the research conducted; if tables and figures/graphs are presented, they should have good captions or legends. The caption of table and figures need to be clear and “self-explanatory” so readers will be able to understand even without reading the relevance text. No need for data presented in tables or given in the form of the figures/graphs, to be repeated in words, in the text. The presented data are then discussed and compared to published results of previous similar studies, if any. New findings or innovations obtained as well as the contribution of the results conducted to the advancement of science need to be described in order to give more weight of the discussion of the results obtained.
Conclusions
Conclusions section presents a resume of research result, which is drawn following the discussion of the results in the “Results and Discussion” section. Conclusion may take the form of narration or of points of statement.
Acknowledgement
This section contains a brief written expression of the author(s)’grateful to those who have given contribution to the research conducted, including fund donor(s) and reviewer(s) of draft of manuscript.
References
References section presents all references used in the preparation of the manuscript. They should be listed alphabetically according to the name of first author of the respective article. Each reference should be written completely. Considering the many ways to write a reference, herein this journal, the Harvard System is used as a standard, with the following examples to write a reference of: thesis, books, seminarsproceedings, journals and papersin a conferences, consecutively.

The following are the ways to write a referred literature in the text part of manuscript:
- For a literature written by one author, Deka (1987) or (Deka, 1987); for a literature written by two authors, Takashima & Speece (1998) or (Takashima & Speece, 1998) and for a literature written by more than two authors, Soedjanaatmadja etal., (1994) or (Soedjanaatmadja etal., 1994).
- For literatures written in languages other than Indonesian language, use etal., but for literatures written in Indonesian language, use its Indonesian synonym, dkk.
