Specific Instructions

The manuscripts must be composed of the following scientific article components (subtitles-in order), as follows:

1. Article Title: Identify the main issue of the article. Begin with the subject of the article. The title should be accurate, unambiguous, specific, and complete. Do not contain infrequently-used abbreviations.
2. Authors Name and Affiliations: Write Author(s) names without a title and professional positions such as Prof, Dr, Production Manager, etc. Do not abbreviate your last/family name. Always give your First and Last names. Write clear affiliation of all Authors. Affiliation includes a name of department/unit, (faculty), a name of university, address, country. Please indicate Corresponding Author (include email address) by adding an asterisk (*) in superscript behind the name.
3. Abstract and Keywords: An abstract should stand alone, means that no citation in the abstract. Consider it the advertisement of your article. The abstract should tell the prospective reader what you did and highlight the key findings. Avoid using technical jargon and uncommon abbreviations. You must be accurate, brief, clear and specific. Use words which reflect the precise meaning. The abstract should be precise and honest. Please follow word limitations (100‐150 words). Keywords are the labels of your manuscript and critical to correct indexing and searching. Therefore the keywords should represent the content and highlight of your article. Use only those abbreviations that are firmly established in the field. Each keyword is separated by a semicolon (;).
4. Introduction: In Introduction, Authors should state the objectives of the work at the end of introduction section. Before the objective, Authors should provide an adequate background, and very short literature survey in order to record the existing solutions/method, to show which is the best of previous research, to show the main limitation of the previous research, to show what do you hope to achieve (to solve the limitation), and to show the scientific merit or novelties of the paper. Avoid a detailed literature survey or a summary of the results. Do not describe literature survey as author by author, but should be presented as the group per method or topic reviewed which refers to some literature.

   Example of novelty statement or the gap analysis statement at the end of Introduction section (after state of the art of previous research survey): “........ (short summary of background)....... A few researchers focused on ....... There have been limited studies concerned on ........ Therefore, this research intends to ................. The objectives of this research are .........”.

5. Research Methods: The research method describes the stages of research/development undertaken to achieve the objectives/outputs of research.  Each stage is briefly described (eg each step in a paragraph). Also inform the materials/platforms used in the study, including the subjects/materials, the tools/software used, the design or experiment used, the sampling technique, the test plan (the variable to be measured and the data retrieval technique), analysis and statistical model used.
6. Results and Discussion: Results should be clear and concise. The results should summarize (scientific) findings rather than providing data in great detail. Please highlight differences between your results or findings and the previous publications by other researchers. The discussion should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

   In the discussion, it is the most important section of your article. Here you get the chance to sell your data. Make the discussion corresponding to the results, but do not reiterate the results. Often should begin with a brief summary of the main scientific findings (not experimental results).

   The following components should be covered in the discussion: How do your results relate to the original question or objectives outlined in the Introduction section (what/how)? Do you provide interpretation scientifically for each of your results or findings presented (why)? Are your results consistent with what other investigators have reported (what else)? Or are there any differences?

7. Conclusions: Conclusions should answer the objectives of the research. Tells how your work advances the field from the present state of knowledge. Without clear Conclusions, reviewers and readers will find it difficult to judge the work, and whether or not it merits publication in the journal. Do not repeat the Abstract, or just list experimental results. Provide a clear scientific justification for your work, and indicate possible applications and extensions. You should also suggest future experiments and/or point out those that are underway.
8. Acknowledgments (Optional): Recognize those who helped in the research, especially funding supporter of your research. Include individuals who have assisted you in your study: Advisors, Financial supporters, or may another supporter, i.e. Proofreaders, Typists, and Suppliers, who may have given materials. Do not acknowledge one of the authors' names.
9. References: All references referred to in the article text must be listed in the References section. The references shall references from 80% of primary sources (scientific journals, conference proceedings, research reference books).
