Tanzania Journal of Engineering and Technology was formerly known as Uhandisi Journal. The Uhandisi Journal was established in 1974 by the then Faculty of Engineering (FoE) of the University of Dar es Salaam. From 1974 to 2005, the Journal was published in print form only and came out twice a year. FoE became the College of Engineering and Technology (CoET) of the University of Dar es Salaam in 2006. Between 2005 to 2006, CoET decided to upgrade the Uhandisi Journal to serve the wider engineering and scientific community in a fast-changing technological world.

Initial efforts were made to digitize all Uhandisi Journal articles and store them in a digital archive. Then, Uhandisi Journal was changed to Tanzania Journal of Engineering and Technology (TJET).

TJET is the platform for communication and dissemination of scientific articles ranging from pure and applied sciences; to engineering and technological research between and among engineers, scientists, policy makers, allied professionals and the general public. It is published in both print and electronic by UDSM through CoET and issued thrice a year, in April, August and December. Occasionally, Special Issues are published in between to enable quick and timely dissemination of research findings, e.g., from peer reviewed and presented conference papers.

The journal can be accessed on Journal link and AJOL link.

All articles are open access to the public domain. Authors are not charged article processing charges (APC) or whatsoever. TJET aligns with open science and open research modus operandi to make all knowledge free.

Disclaimer and Copyright

In order for TJET to publish and disseminate its research articles, publishing rights from authors are required, which are determined by a publishing agreement or UDSM Journal Policy and Guidelines between the author and TJET. Author rights include retention of patent and trademark rights, retain the rights to use their research data freely without any restriction; cite their own material in new works without permission or payment; and share the article.

Author(s) can archive pre-print, post-print, and published version/PDF to any open access, institutional repository, social media, or personal website provided that Published source must be acknowledged with citation and link to publisher version.

Plagiarism is not acceptable with TJET. All submissions will be subjected to assessment for any possible plagiarism using Turnitin tool.

Authors must solicit permission to reuse any third-party material (photographs, data, illustrations, table, etc.) in their manuscript. Similarly, this applies to all works extracted from other copyrighted materials.

Review Process

Tanzania Journal of Engineering and Technology (TJET) uses a double-blind peer review system in which reviewer and author identities stay anonymous to the other party throughout the review process.

This Journal uses Open Journal Systems (OJS) 3.3.0-4 and follows the OJS editorial and publishing process, which allows the author(s) to track the review process.

The following elements detail the overall review process. 

  1. Submission of Manuscript

The corresponding author(s) may submit the manuscript online through the following link. However, before submission, the author(s) must ensure the manuscript conforms to Author guidelines and Instructions for authors.

  1. Editorial Office Assessment

The Journal Editor-in-Chief checks the manuscript's plagiarism using Turnitin and conformity against Author guidelines and Instructions for authors.

The Editor-in-Chief also checks the originality and contents of the manuscript to confirm their relevance for the journal.

At this stage, the Editor-in-Chief may accept or reject initially screened the manuscript during desk review.

  1. Assignment of Manuscript to Subject Editors

The Editor-in-Chief may assign the screened manuscript to the Subject Editor responsible for the peer review process.

  1. Invitation to Reviewers

The subject Editor sends invitations to at least three potential individuals competent in the field covered in the manuscript.

Potential reviewers may accept or decline the invitation against their own expertise, availability and conflicts of interest.

At least two independent reviewers must review one manuscript. Depending on the responses received, the Editor-in-Chief or Subject Editor may request additional reviewers to review the manuscript.

  1. Review is conducted

The reviewer assesses the manuscript and provides feedback within the set time. The reviewer’s response must comply with the peer reviewer guidance.

Afterwards, the reviewer should provide the recommendation to accept the manuscript as it is, accept it with minor corrections, accept it subject with major corrections, or reject it.

  1. Evaluation of the Reviews

The subject editor or Editor-in-Chief considers all the returned reviews before making an overall decision.

If the reviews differ widely, the editor may invite an additional reviewer to get another independent opinion before proving the overall decision.

  1. Communication of the Decision

The editor sends a decision e-mail to the author(s), including any relevant reviewer comments.

If accepted, the manuscript is sent to production. If the manuscript is sent back with major or minor revisions, the editor will include constructive comments from the reviewers to help the author(s) improve the manuscript.

Manuscripts that require major revisions will be sent back to the reviewers after contributors have made changes to the manuscript in accordance with reviewers' comments.

The subject editor may handle manuscripts that require only minor changes. The corresponding author(s) of the rejected manuscript will be informed accordingly.

Notes for Peers Review

Tanzania Journal of Engineering and Technology (TJET) is grateful to the reviewers who devote their expertise, energy, and time to review manuscripts submitted to this Journal.

The Journal uses a double-blind peer review system in which the reviewer's identity will always remain confidential to the author(s). Thus, the reviewer is requested to ensure that the review and any attachments do not indicate his/her identity as a reviewer.

To ease the review process, the following outlines are possibly useful to the reviewers:

  1. To ensure that our Journal publishes manuscripts of high quality, reviewers must provide the Editorial Board with critical constructive comments of the highest academic standards. The manuscript quality depends on the ‘dialogue’ between authors and reviewers, mediated through the editorial process, to obtain a manuscript with acceptable excellence. Thus, a reviewer must provide authors with detailed feedback and clear and specific suggestions for manuscript improvement.
  2. To ensure that author(s) receive decisions on the outcome of the review process, reviewers are kindly requested to complete reviews within the time frame provided. Reviewers who need extra time may request an extension through the Subject Editor or Editor-in-Chief via the online journal system. The Journal intends to inform the authors’ outcome as early as possible.
  3. The subject editors try to assign manuscripts in accordance with the reviewer's fields of expertise. If the reviewer can not evaluate the manuscipt based on competing interest or any other acceptable reasons, He/She is requested to inform the editorial board as soon as practicable.
  4. The review process aims to identify areas of improvement of the manuscript. Thus, the reviewer is expected to provide constructive suggestions for manuscript improvement. The reviewer can recognise and acknowledge strong points where appropriate while avoiding provocative comments and non-inclusive languages.
  5. The reviewer may write comments directly on the manuscript, but He/She is also expected to fill out the online form.
  6. The reviewer is kindly requested to review a revised manuscript of the author(s) to enhance coherence and expedite the reviewing process. However, He/She can opt to decline in exceptional cases
