Author Guidelines

General author guidelines

The Helium: Journal of Science and Applied Chemistry (He: JSAC) uses a web-based online manuscript submission and review system. The author must register in the registration section. Authors must submit their manuscripts via the online submission system on the He: JSAC page

https://journal.unpak.ac.id/index.php/he_jsac

The manuscript must be written and submitted in .doc or .docx format. Please consult our template user guide for help when using our Microsoft Word templates:

If authors have any problems with the online submission, please contact Editorial Office at the following email: he_jsac@unpak.ac.id

General Instructions

Any manuscript submitted to the He JSAC must follow the following instructions. The article that does not comply with the guidance will be returned to the author without further review. The manuscript has to be written in English. The manuscript is written with correct spelling, sentences, and paragraph arrangements corresponding to the grammar used. Helium: Journal of Science and Applied Chemistry uses IEEE style for the citation and references. (Please use Mendeley App)

Specific Instructions

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

Title. 

Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.

Author names and affiliations.

Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. You can add your name between parentheses in your own script behind the English transliteration. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lowercase 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.

Corresponding author. Please clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication, by underlining the name. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address of all authors is given and that contact details are kept up to date by the corresponding author.

Present/permanent address. If an author has moved since the work described in the article was done or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

Abstract.

The abstract should stand alone, which means no citation in the abstract. Consider it as the advertisement for 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 that reflect the precise meaning, Abstract should be precise and honest. Please follow word limitations (100-300 words).
Keywords. Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

Introduction.

Authors should state the objectives of the work at the end of the introduction section. Before the objective, the Authors should provide an adequate background and a 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.

Methods.

Methods should make readers able to reproduce the experiment. 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. Do not repeat the details of established methods. For the chemicals, please provide details of brand and purity (example: CaO (Merck, 99.5%)).

Results and Discussion.

Results should be clear and concise. The results should summarize (scientific) findings rather than provide 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 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)? Do you provide an 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?

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.

Acknowledgments.

Collate acknowledgments in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance, proofreading the article, etc.). If authors refer to themselves as recipients of assistance or funding, they should do so by their initials separated by points (e.g. I.J.SE.). Do not acknowledge Editors by name. Formatting of funding sources List funding sources in this standard way to facilitate compliance with the funder's requirements: Funding: This work was supported by the Directorate General of Higher Education of the Republic of Indonesia [grant number zzzz]; Diponegoro University [grant numbers xxxx, yyyy].

References.

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, however, may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. The citation of a reference as 'in press' implies that the item has been accepted for publication. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter, and the pagination must be present. The use of DOI is highly encouraged. Note that missing data will be highlighted at the proof stage for the author to correct. Example:

Reference style Text:

Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given. Example: '..... as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result ....' List: Number the references (numbers in square brackets) in the list in the order in which they appear in the text.
