The main body includes the introduction, research methodology, results and discussion, and conclusion..

Submitted manuscripts must be prepared in Microsoft Word format (.doc or .docx) with a file size not exceeding 2 MB.

 Margins

The article must be prepared using Microsoft Word on A4 paper with the following margins: top 3 cm, left 3 cm, bottom 3 cm, and right 2.5 cm.

Header and Page Numbering

The article, including the title, introduction, and references, must have an even number of pages with a maximum of 10 pages. Add one blank page if the total number of pages is odd.

Odd page numbers are placed at the bottom right, while even page numbers are placed at the bottom left. Page numbers use Times New Roman, 10 pt, italic.

The header on odd pages includes the journal name, Jurnal Teori dan Aplikasi Fisika, on the left and the volume, issue, month, and year of publication on the right. Volume and issue are filled by the editor and may be written as “XX” during submission. The header uses Times New Roman, 10 pt, italic.

The header on even pages contains the author’s last name followed by the full article title separated by a colon. If there are multiple authors, the last name of the first author is written followed by “et al.” The text uses Times New Roman, 10 pt, centered.

 Text and Paragraphs

The main text is written in two columns (column width 7.5 cm, column spacing 0.5 cm) justified on both sides. The text uses Times New Roman, 12 pt, single spacing. Each paragraph begins with a 0.75 cm indentation and no extra spacing between paragraphs.

Titles, Sections, and Subsections

The article title must be concise and clearly describe the content. It is written in Times New Roman, 16 pt, bold, centered, using capital letters for each major word, with single spacing and 12 pt spacing after.

Section headings use Times New Roman, 12 pt, bold, centered, uppercase, single-spaced, with 12 pt spacing before and after.

Subsection titles use Times New Roman, 12 pt, bold, left-aligned, without numbering. Each major word begins with a capital letter. They use single spacing with 12 pt spacing before and after.

Numbered lists within subsections use Arabic numerals. The text uses Times New Roman, 12 pt, left-aligned, single spacing, with 12 pt spacing before.

Author Profile

The author profile consists of the author’s name, affiliation, and email address. The name appears after the article title in Times New Roman, 14 pt, centered, single-spaced, with 12 pt spacing after. If two authors are listed, their names are joined with “and”. If more than two, names are separated by commas except the last two, which are connected with “and”.

Middle and last names may be abbreviated with initials if too long. Full names are preferred. The corresponding author may be marked with “*” at the end of their last name.

If authors come from different institutions, each name is followed by a numbered footnote in parentheses indicating their affiliation. If all authors are from the same institution, no footnote is needed.

If multiple email addresses are provided, each email is indicated with a lettered footnote in parentheses. A single email does not require a footnote.

Affiliations appear below the author names in Times New Roman, 10 pt, centered, italic, single-spaced. Each affiliation is written in two lines: the first line contains the full institution name, and the second line contains the address (street name and number, city/regency/province, postal code, and full country name).

Email addresses are written below the affiliations using the same formatting with 24 pt spacing after. Multiple emails are separated by commas and given lettered footnotes.

After the profile, include submission and acceptance dates in the format: “Received (Day Month Year), Revised (Day Month Year).” The text uses Times New Roman, 12 pt, centered, single-spaced, with 24 pt spacing after.

Abstract

The abstract consists of a single paragraph written in English and Indonesian (English first). It contains a concise summary of the article, including research objectives, methods, results, and conclusions. It may not include table descriptions, figure descriptions, citations, or mathematical equations. The abstract uses Times New Roman, 10 pt, justified, single-spaced. The English abstract is italicized. The maximum length is 300 words.

Keywords represent the core concepts of the article and should not be taken directly from the title. They use Times New Roman, 10 pt, with a maximum of five keywords. There should be a 12 pt spacing between the abstract and keywords.

Introduction

The introduction explains the research problem and its objectives, along with the scope of the work and the scientific theories supporting it. It should also include the plan for solving the problem and a hypothesis.

The introduction must highlight the novelty of the research compared with related works and therefore requires supporting references.

Figures

Figures must be high-quality JPG files with a minimum resolution of 300 dpi. All details, including text within figures, must be clearly visible. Each figure requires a caption that briefly and clearly describes its content.

Figures must be placed at the top or bottom of a column, not in the middle. They should be centered, and large figures may span the full page width. Add 12 pt spacing between the figure and paragraph text.

Figure captions appear below the figure, single-spaced, with 12 pt spacing before and after. Captions use Times New Roman, 10 pt, and include a bold figure number followed by a period. Single-line captions are centered; multi-line captions are left-aligned, with the second line aligned to the text, not to the figure number.

Figure numbers in the text are written in bold. Figures may be mentioned before they appear. More detailed explanations of the figures must appear in the main text.

Tables

Tables must be placed at the top or bottom of a column. Text inside tables uses 11 pt font; if necessary, it may be reduced to 9 pt. Large tables may span the full page width. Add 12 pt spacing after each table. Only the top and bottom horizontal lines and the line separating column labels from table entries should be shown.

Table captions appear above the table, single-spaced, with 6 pt spacing after and 12 pt spacing before. Captions use Times New Roman, 10 pt, with a bold table number followed by a period. Single-line captions are centered; multi-line captions are left-aligned with the second line aligned to the text.

If a table continues into the next column, repeat the column labels without repeating the caption.

Table numbers in the text are written in bold. Tables may be referred to before appearing and must be explained in detail in the paragraph text.

 Equations

Equations must be typeset using MathType. Each equation must be numbered in parentheses, aligned to the right margin of the column. Use 12 pt spacing before and after each equation. Multiple consecutive equations are separated by 6 pt spacing.

Equation references in the text are written as “Equation X”, where X is the equation number. Equations may be mentioned before they appear.

Symbols and units used in equations must be explained in the text using standard units. Example: In Equation 2, F = net force (N), m = mass (kg), a = acceleration (m/s²).

Citations

References must follow the IEEE citation format. Citations in the text appear as numbers in square brackets, such as [1] or [1,2], corresponding to entries in the Reference List. Each article must include at least 15 references, with 80% from journals published within the last 10 years. Avoid using unverified internet sources. Examples of IEEE references are provided in the Reference List section.

Research Method

This section describes in detail the methods and procedures used to solve the research problem. Any experimental design, such as electronic circuits, mechanical systems, or supporting designs, must be presented thoroughly. The method must enable the study to be replicated with the same results.

Results and Discussion

This section presents research data, which may be displayed in tables or figures when appropriate. Each dataset must be clearly described and easy to understand.

The findings must be linked to the research objectives and supported by references, highlighting the novelty of the study compared with previous works. The discussion must relate the findings to the theoretical background and the hypothesis, integrating all components into a coherent scientific explanation.

Conclusion

The conclusion summarizes the essential findings clearly and concisely, answering the research problem and aligning with the research objectives.
