IRAJTMA Manuscript Structure

1. Title: Written in both languages (Indonesian and English) for articles in Indonesian,Meanwhile, English-language articles only need to be written in English and should not exceed 16 words.
2. Authors: The author’s full name and institution address must be clearly stated.
3. Abstract: For IRAJTMA, the abstract must be clear, concise, and accurately reflect the content of your article. If the article is in Indonesian, the abstract must be written in both Indonesian and English. If the article is in English, the abstract need only be written in English. The abstract must briefly address the research questions by covering the following: the subject of your research (background/problem), the objective, the methods used, the key findings (not the discussion), and your conclusion. Careful consideration should be given to the abstract, as it is a primary element of your work that readers will see. It must consist of a short paragraph of no more than 150–200 words. The abstract must not contain citations, abbreviations, figures, tables, or footnotes.[Calibri, 10pt, Justified, Normal].
4. Keywords: Consist of 3-5 words that can be used to search the article.
5. Introduction: Background, theoretical review, and research objectives must be implicitly stated in the introduction. Manuscripts must be prepared using the Microsoft Word template on A4 paper (margins: 2.5 cm left; 2 cm right, top, and bottom) in accordance with the template's guidelines. The maximum length is 10 pages for original research articles or 15 pages for review articles. The Introduction covers the background of the issue or problem, as well as the urgency and rationale for the activity (research or community service). Rather than merely a compilation of literature, the Introduction should present a logical thread demonstrating the need for new research; the structure for the IRAJTMA Introduction is as follows:
   Paragraph 1: Authors are required to state the main problem of interest that has been addressed by previous researchers (citing journal literature from the last 5 years). The problem must be presented objectively, based on scientific facts and supported by relevant references, rather than relying solely on the authors' perspectives or assumptions. Clearly articulate the problem, its importance, and the consequences of leaving it unresolved [Calibri, 12pt, Normal, Justified, first-line indent].
   Paragraph 2: Narrow the discussion from the general problem to the specific issue aligned with the research focus. Explain the key variables related to the problem and the reasons why this aspect requires investigation.
   Paragraph 3: Present the "state of the art" by summarizing and synthesizing the methods and key findings of previous research from the last 5 years. Focus the discussion on the most relevant studies that demonstrate the evolution of knowledge regarding the issue under study. Authors must describe previous research efforts and outcomes in addressing the outlined problem. Detail the methods and main results of prior studies, then identify limitations and unresolved issues (the research gap).
   Paragraph 4: Identify the limitations and shortcomings of previous research to establish the research gap. Offer an objective and balanced scientific critique regarding the strengths and weaknesses of earlier studies. Next, explain the idea, approach, or solution proposed to bridge the gap, thereby justifying the study's novelty as evidenced by the identified research gap and the contribution offered. Finally, outline the scientific rationale supporting the relevance and logic of the proposed approach and its potential to contribute to solving the problem.
   Paragraph 5: Explain the approach or solution proposed to address the research gap, highlighting the study's novelty. Demonstrate the distinctions and contributions of your research from a scientific perspective without explicitly claiming it to be the "first" or "pioneering" study of its kind.
   Paragraph 6: Clearly and specifically state the research objectives based on the identified research gap, then briefly explain the study's primary contribution to the advancement of knowledge, methods, technology, or their applications. Ensure that the objectives and contributions align with the research methods and results, and provide a lead-in to the methodology section.
   Only relevant references and hypothesis development (if applicable) should be included (cited) in this section. This introduction section is written without subheadings. [Font: Cambria, size 12, normal, 1.15 line spacing]. The complete article typically follows the standard IMRaD structure: Introduction, Methods, Results, and Discussion [Calibri, 12pt, Normal, Justified, first-line indent].
6. Methods: All significant methods, including key materials used in the research, must be explained here. The Methods section must not contain results or interpretations of results. It should only describe what was done, how it was done, and how the data were analyzed. The section should cover the timing and location of the research, the study design, key materials and equipment, the scope or subject of the study, measurement and data collection methods, research procedures, and data analysis and validation methods. Employ methods relevant to the research objectives. Ensure that all parameters, experimental conditions, sample sizes, treatments, replicates, instruments, and statistical analysis techniques that could influence the results are clearly stated. For experimental research, systematically describe the operating conditions and experimental stages. For modeling, simulation, or computational research, describe the models, assumptions, boundary conditions, parameters, software, and validation methods used. Photographs or images of the materials and equipment used must be clearly displayed, centered, and numbered. Note that the subsections within the Methods section should be presented in the same order as in the Results section, [Calibri, 12pt, Normal, Justify, first line].
   This section presents the theories and formulas used in the research. Every formula displayed must be numbered. Each equation must be centered within the column, with its number enclosed in parentheses and placed at the right-hand margin. Equations must be created using the Equation Editor in MS Word or Open Office.

   All information drawn from references must include the appropriate citation and bibliographic entry. Examples of citation formats include: for a journal reference—"Heat transfer phenomena in the heater can be calculated using Equation 1 (Thombare and Verma 2026)"; for a book reference—"The ideal gas constant for air, Ru, is 0.2870 kJ/kg.K (Çengel and Boles 2004)"; and for a website reference—"Indians spend the most time cooking—averaging over 13.2 hours per week—according to a survey by market researcher GfK (Mukherjee 2015)."
7. Results and Discussion: This section should explain the results, illustrations, interpretations, generalizations of the results, and their relation to previous research. Research results are presented in the form of tables, graphs (figures), and/or charts. The discussion section presents the processed data, interprets the findings logically, and links them to relevant reference sources (citations of previous research). This combined Results and Discussion section should be written as continuous text; the use of subheadings should be avoided whenever possible [Calibri, 12pt, Normal, Justified, first-line indent]. In the Results and Discussion section, authors must present research findings clearly—supported by data and facts—and then analyze and interpret them critically. It is insufficient for authors merely to describe the results; they must explain the significance of each finding, its relationship to relevant concepts or theories, and the scientific rationale underlying the results. Research findings must be critically compared with relevant, recent prior studies to demonstrate whether the current results reinforce, complement, or correct existing knowledge. The discussion must address the identified problem and research gap, while highlighting the scientific contribution of the findings. Avoid discussions that simply repeat data, describe tables or figures, or state that results are "consistent with" or "different from" previous studies without providing a scientific explanation. The primary focus of this section should be the acuity of analysis, depth of interpretation, and quality of synthesis, as well as the ability to substantiate or correct previous findings. The "Results" section presents what was found, whereas the "Discussion" explains the meaning of those findings, why they occurred, how they compare to previous research, and their contribution to the body of knowledge. Conclude the Results section with the most significant finding that serves as the basis for the subsequent discussion.
8. Conclusion: Summarizes the important findings of the research and must be based on facts. The conclusion is stated in alignment with the research objectives outlined in the "INTRODUCTION" section and based on the "RESULTS AND DISCUSSION," reflecting the facts and data derived from the research. Emphasize the study's contributions or key findings rather than merely reiterating results or making general statements. The conclusion is not a summary of the entire article but a concise, definitive answer to the research objectives based on substantiated findings. Additionally, potential applications of the research findings and opportunities for future studies may be included (based on the results and discussion) [Calibri, 12pt, Normal, Justified, first-line indent].
9. Acknowledgments, Author Contributions, Conflict of Interest Statement, Disclosure of AI Use: statements communicated to all parties proportionately.
10. References: Use the Chicago Manual of Style 17th edition (author-date) citation style, and it is recommended to use Mendeley as the reference manager.
11. Each chapter and subchapter should be numbered (e.g., Chapter 1, Subchapter 1.1).
12. Font size in tables 12 pt, Calibri, left-aligned.
13. Figure titles should be written and positioned below the figure, center-aligned.
