1. Introduction (font arial 11 pt, bold)
JUSTINDO (Indonesian Journal of Systems and Information Technology) is a journal published by the Informatics Engineering Study Program, Universitas Muhammadiyah Jember. JUSTINDO publishes both empirical research articles and conceptual papers related to information systems and technology.
This document serves as a template for manuscript preparation in JUSTINDO. Manuscripts should be typed on standard A4-size paper (21 cm x 29.7 cm) in a single-column and single-spaced format. Use margins of 2.2–2–1.8–2 cm (left–top–right–bottom), Arial 11pt font, 1.0 line spacing, and no special indentation.
Manuscripts must be written in Indonesian, with a length of at least 8 pages and no more than 12 pages. Authors are required to follow these writing guidelines. The official template can be downloaded from: http://ejurnal.unmuhjember.ac.id/index.php/JUSTINDO/index
The Introduction section should include the background and problem analysis of the research topic being addressed.
In addition, authors may include a literature review of relevant previous studies, properly cited according to the prescribed reference format.

2. Research Method
This section discusses the methods used in the research. Authors are expected to provide a detailed explanation of the theories, algorithms, or approaches employed in the study. It is also recommended that authors include citations from reputable scientific journals or academic books. (Use of general internet sources is not recommended.)
2.1 Writing Specifications
The following are the writing specifications or formatting rules for articles submitted to the JUSTINDO Journal:
2.1.1 Title Writing
The title must be concise and reflect the content of the manuscript (maximum of 12 words). Avoid using subtitles or case studies in the title. Article titles should be written in both Indonesian and English, centered, and formatted using Arial 12pt, bold, Capitalize Each Word, and single spacing (1.0).
2.1.2 Author Identity
Include the author’s full name (without academic title), affiliation (study program, faculty, university), and email address. Author information must be placed below the title, center-aligned, in Arial 10pt, single-spaced, and italicized. The corresponding author must be identified with an asterisk (*) symbol.
2.1.3 Abstract Writing
The abstract (150–250 words) must be written in both Indonesian and English, followed by keywords (minimum 3 and maximum 5). Use Arial 10pt, single spacing. The English abstract should be italicized.
2.1.4 Main Article Content
The main article should use Arial 11pt, single spacing (1.0), and justified alignment. The article generally consists of the following main sections: Introduction, Research Method, Results and Discussion, and Conclusion. Headings must be written in uppercase letters, preceded by numbering, and formatted using the predefined heading styles in this template. These styles are designed to ensure consistent spacing and hierarchical numbering for headings and subheadings.

3. Results and Discussion
The Results and Discussion section describes the implementation process and testing procedures conducted in the study. This section should clearly demonstrate the author’s contribution to scientific advancement. Moreover, it must include the experiments and analyses carried out, presented in a clear and structured manner such as through block diagrams, flowcharts, or other relevant visual aids.
All tables and figures must be clear (not blurred or pixelated). The font size used in tables and figures must be easily readable by the naked eye. Examples of proper formatting are provided in Table 1 and Figure 1.
3.1 Table
Table numbers and titles must be centered. Tables are numbered using Arabic numerals in order of appearance. Table titles are written above the table in Title Case, except for conjunctions and prepositions. The font size for both the table title and its contents should be 8 pt.
The outer edges of the table should not exceed the page margins. There should be one blank line between the table and the text above or below it. Tables must follow the layout of Table 1, and vertical lines should not be used. Each table must be referenced in the text, beginning with a capital letter for example, Table 1.

3.2 Figures
Figure numbers and titles must be centered. Figures are numbered sequentially using Arabic numerals. Figure titles are written below the figure, using Title Case (except for conjunctions and prepositions), with a font size of 8 pt. Figures should not exceed the page margins.

There should be one blank line between the figure and the surrounding text. It is recommended to use grayscale or black-and-white images, unless color is necessary for clarity. If printed in grayscale, differences between data representations (e.g., lines or markers in a graph) must remain distinguishable. Each figure must be referred to in the text, beginning with a capital letter — for example, Figure 1.

3.3 Mathematical Equations
All formulas or equations must be created using Equation Editor or MathType (http://www.mathtype.com). Equations should start aligned to the left margin, consistent with the text above them. Each equation must be numbered sequentially in parentheses on the right margin and referenced in the text. All symbols used in equations must be defined, either before or after the equation. For example, Equation (1) shows how to determine the baud rate frequency in Mode 2 serial communication for an 8051 microcontroller:

3.4 Other Provisions
All manuscripts are reviewed under a double-blind peer-review process by experts (reviewers) appointed by the editorial board according to their fields of expertise. Authors will be given the opportunity to make revisions based on reviewers’ and editors’ recommendations. Acceptance or rejection of manuscripts will be communicated via email.
Proofreading and layout editing are conducted by the editorial team, with possible involvement of the author(s). A manuscript that has entered the proof stage may still be withdrawn by the editor if significant issues are discovered.
Any matters related to copyright permissions, software usage, or intellectual property rights (IPR) arising from the manuscript are the sole responsibility of the author(s), including any potential legal consequences.

4. Conclusion
The Conclusion section presents the final summary and findings derived from the research. Authors are encouraged to include supporting data that strengthen the conclusions drawn. This section should also reflect the strengths and limitations of the research, as well as offer recommendations for further studies or potential improvements in future research.

Acknowledgment (Optional)
The Acknowledgment section should only be included if necessary, for example: to recognize funding sources, to acknowledge data access or research assistance, or to express gratitude to individuals or institutions that contributed to the completion of the research or manuscript.

References
References should, as much as possible, consist of publications from the last 10 years. Priority should be given to research articles published in journals, conferences, or scientific magazines. Other references may include textbooks, research reports, theses, or dissertations, but should not exceed 20% of the total references.
The reference list must be formatted using a reference manager (e.g., Mendeley or Zotero) with the Harvard citation style, and must include the DOI or URL for online versions.
Additional formatting rules: All references listed must be cited in the text. References are arranged alphabetically without numbering. Multiple works by the same author are ordered chronologically by year. If multiple works were published in the same year, distinguish them with letters (e.g., 2011a, 2011b, 2011c).
