The Philippine Engineering Journal (PEJ) serves as a national medium of exchange of technical information and dissemination of engineering knowledge through the publication of original technical papers such as original articles, review articles, or short communications in the field of engineering. Published semi-annually by the University of the Philippines National Engineering Center (UP NEC), it is being distributed at reasonable rates to schools, professional organizations, international entities, and practitioners. PEJ articles may be accessed on U.P. Diliman Journals Online (


The PEJ invites authors who wish to publish their works in the fields of chemical engineering, civil engineering, computer science, computer engineering, electrical engineering, electronics and communications engineering, geodetic engineering, energy engineering, environmental engineering, industrial engineering and operations research, materials engineering, mechanical engineering, metallurgical engineering, mining engineering, and other engineering fields. Should you be interested to submit a manuscript, please refer to the guidelines below.

  1. B.        Manuscript Content and Format


Manuscripts shall be submitted in editable electronic form written with page layout specified for A4 paper size.  Non-editable form of the same may be included in your submission for reference. The maximum number of pages depends on the type of manuscript.


The manuscript typically contains the following: Abstract, Keywords, Introduction, Methodology, Results and Discussion, Conclusion and Recommendation, Acknowledgment, and References. Since PEJ follows a double-blind peer review, the author should prepare a manuscript with no identifying author information and affiliation. However, a separate title page should be prepared with the author details (full name, affiliation, corresponding author's email) and abstract of not more than 300 words.


Abstract. An abstract not exceeding 300 words must accompany the original article, review article, and short communication.


Keywords. Provide keywords relevant to the paper or identifiable words related to the paper. This will facilitates online searches of your manuscript.


Introduction. This section provides a brief background and significance of the paper and discussion of related previous works (literature review/survey), the relevance of the topic being reported or problem addressed, the solution, and objectives. In the case of the review article, the main purpose of the review should be the focus of the introduction.


Methodology. This section may be devoted to the detailed description of the experimental process or investigation, including the apparatus, materials, equipment, and methods of analysis and characterization. This section may contain only the bare essentials in the case of short communications.


In the case of original articles and short communications, a section should be devoted to the detailed discussion of the results, their accuracy, and how they compare with the results of other workers, if available.


Conclusions and Recommendations. This section summarizes the conclusion, observations, or recommendations of the authors.


Acknowledgments. Placed in a separate heading before the references, brief statements about the funding support and/or personal assistance, if any, may be placed under this section. If there is any identifying author’s information in the acknowledgment section that may compromise the double-blind peer review, the author can send it as a supplemental file not for review or can be included in the cover letter. This acknowledgment section will be included later in the final proofing if the manuscript is accepted for publication.


References. References should list the name(s) of the author(s), year of publication, the title of reference materials, volume, and page numbers.


Nomenclature. A list of symbols and abbreviations, if applicable, can be provided in a section called Nomenclature for technical papers, review articles, and short communications.


An appendix may be added to discuss the derivations of equations, an algorithm of programs used, and the like if these derivations, algorithm, etc. do not fit in the text for the reason of space, style, etc. but must be included for completeness, clarity, and or additional supplementary information to the reader.


All technical papers submitted will be subjected to a double-blind peer review process.


Pages. All pages shall have the following dimensions:


Left margin                              1.0 inch

Right margin                            1.0 inch

Top margin                              1.0 inch

Bottom margin                         1.0 inch

Header (first page only)            0.5 inch

Footer                                      0.5 inch


The header, which shall contain the date of issue of the PEJ, should be left blank by the author.


Pagination should be automatic and should be right-aligned on the last line of the footer.


Paragraphs and Font. All lines of the main text should be double-spaced and one line of spacing must separate paragraphs. The text shall be written in MS Word using 12-point Times New Roman font. The abstract should be written single-spaced, italicized, and using 10-point Times New Roman font.


Headings. Main headings should be numbered using Roman numerals and written in boldface, e.g., I. Introduction, II. Methodology, and so on. Sub-headings should be numbered using Arabic numerals and written in Italics, i.e., 2.1 Characterization. The heading of the abstract should not be numbered. All headings should be left-aligned.


Captions. All drawings, photographs, graphs, and similar graphical material should be labeled and numbered consequently. A brief caption describing the content should appear. The label should be in boldface while the caption should be plain. Thus, an example would be:


Figure 1. Schematic diagram of the experimental apparatus


The label and caption should appear centered below the figure it describes and separated from the figure by only one line of space. Likewise, tables should be labeled and numbered consecutively. The label should appear centered above the table and should be written boldface.


Table 3. Comparison of conductivity data from literatures


Sub-labels should be numbered as Figure 3a, Table 2c, etc. A figure or a table label should be separated from succeeding or preceding text by a line of spacing.


Equations. All equations should be centered and numbered, the numbering being right-aligned. If possible, the authors should write equations using an equation editor.


ReferencesReferences should be numbered and listed in the order in which they are cited in the main text. Indicate references by number(s) in square brackets. Should the names of the authors be mentioned in the text, the reference number should also be indicated.


Example: “…as described [12,14]. Suarez and Cortez [15] used a different approach…”


The references section should follow the following formatting. Only published articles, data, or information should be included in the references. Personal communication should appear only in text with the names of the person/s who supplied the information and should not be listed in the References section.
